Ltd., which was published as WO 2019/095583 on May 23, 2019 and based on China patent application 201711142295.6 filed Nov. 17, 2017, the disclosure of which is incorporated herein by reference. 
    
    
     TECHNICAL FIELD 
     The invention relates to the field of artificial stone texture processing, in particular to an interlayer mixing device for artificial stone plate texture processing. 
     BACKGROUND 
     Artificial quartz stone countertops are one way to liven up a kitchen or bath and provide a high-end durable material. Artificial quartz stone has more than 90% natural quartz and about 10% color material, resin and other additives that adjust adhesion, curing, etc. Artificial quartz stone slab also called a plate is processed by negative pressure vacuum, high frequency vibration molding, heating and curing production methods. 
     To make artificial quartz stone countertops less artificial looking, it is desired to have nonuniform texture such as in natural stone slabs. In the existing artificial quartz stone technology, in order to create a texture trend effect similar to natural stone, it is necessary to put a texture mold frame in the fabric process. After the fabric is finished, the texture mold frame is removed, and the material produced shows a texture line. The disadvantages of this technology are: (1) a texture mold frame can only make a texture line effect, and to change the texture line, the texture mold frame must be retooled; (2) filling the texture line with colorant requires manual operation, and lacks production automation; and (3) the texture effect lacks a gradient of multiple color materials, which is very different from real natural stone texture.

The length direction of the pressing roller is perpendicular to the conveying direction of the slab. Both ends are rotatably disposed on the rotating base, and the rotating base is disposed on the frame through a wheel body, so that when the pressing assembly slides along the conveying direction of the slab material, the pressing roller squeezes and rolls over the end face of the slab.

     As shown in  FIG. 1 , an interlayer mixing device for artificial stone slab texture processing includes a pressing assembly  5 , a coloring component  4 , a stirring component  2 , a moving assembly  1  and a control system. The plates are sequentially conveyed by conveyor belt to transport material to the working area of the pressing material assembly  5 , the color application component  4 , and the stirring assembly  2 . The pressing material assembly  5 , the coloring component  4 , the moving assembly  1 , and the stirring assembly  2  are connected to the control system. 
     The control system adjusts the pressing assembly  5  so that the pressing roller  51  applies a squeezing force to the stone material. The coloring component  4  applies color material to at least one surface of the layer to which the pressing force has been applied. Layer color material or according to the design path of the final product texture, applies at least one layer of color material at the corresponding position on the surface of the slab material. 
     The control system adjusts the moving assembly  1  and the stirring assembly  2  so that the moving assembly  1  drives the stirring assembly  2  above the slab after the squeezing force is applied, and according to the setting of the final product texture. As the stirring assembly  2  moves along its route, the stirring assembly  2  stirs at all programmed positions or partial corresponding positions on the surface of the slab, so that stirring occurs between the color material layer applied on top and the raw material mixture layer underneath. 
     The pressing assembly  5  and the stirring component  2  can be mounted together at the same station, or can be mounted separately as two independent stations connected by a belt. Driven by the belt, the stirring component  2  can be moved to the working area of the pressing assembly  5 . The pressing assembly  5  applies a certain squeezing force to the slab or plate, and then, the color component  4  applies at least one layer of color to the surface of the slab or plate. According to cosmetic design, the color component  4  path of the final product texture, applies at least one layer of color material uniformly or unevenly on the corresponding position of the working surface. After application of the coloring material is completed, the moving assembly  1  drives the stirring assembly  2  to move along the extending path of the final product texture. At the same time, the stirring assembly  2  performs the stirring at the corresponding position according to the preprogrammed texture and design to facilitate stirring between the coloring material on an upper material layer and the raw material mixture on a lower material layer. The depth of the stirring may involve the thickness of the entire slab. The position of the agitated position after stirring and the position of the unstirred position will produce a color difference. Inside the mixture, after the texture processing and subsequent curing, pressing, thickness setting and other processes are completed, a transparent texture effect is left on the surface of the slab. 
     Before mixing, a certain squeezing force is applied to the slab material through the pressing assembly  5 , so that the mixing occurs between the raw material mixture and the color material of the more compact plate material, and the material at the mixing position becomes loose again, and the material in the adjacent unstirred position is compacted due to the previous pressing, and there is a large barrier that allows the colorant to penetrate, so that the colorant is well maintained at the position where it is stirred, macroscopically making the final product textured. The boundary is clearer and more complete, and the consistency of the upper and lower textures and the texture permeability are good. The texture effects of the surface and the bottom layer are very clear, which truly achieves the natural crack effect. 
     For the specific implementation of the pressing assembly and the stirring component, there are the following two general embodiments. 
     Example 1 
     As shown in  FIG. 1  and  FIG. 2 , the pressing assembly  5  and the stirring assembly  2  are independently set at two stations, and the coloring component  4  also called the color application assembly enters the design area after squeezing force is applied. Before the working area of the stirring assembly  2  is defined, color material is applied to the surface of the slab. 
     The pressing assembly  5  and the stirring component  2  are set on two independent stations that are relatively spaced apart from each other. The slab can be handled so that it is movable such supported on a slab conveyor belt so that the slab passes the working area of the two components pass over the working area to complete their respective functions. Alternatively, the two components can be mounted at a single station or separately. The mounting locations reduce the time that the slab stays in one station, and reduces the waiting time for the next slab to start processing, thereby compacting the product process time and improving production efficiency. In addition, in a relatively independent station, one may operate variations of the process, although a flexible combination arrangement is required, where multiple pressing assemblies  5  and/or stirring components  2  can also be added in the middle according to process requirements, so as to achieve a richer texture effect. 
     In this embodiment, one of the corresponding setting methods of the color application component (that is, the first implementation of the application coloring component) is performed by a common dusting method, as shown in  FIGS. 4 and 5 . The conveying path of the conveyor belt, includes thereon a cloth hopper  41 , a discharge roller  42  and a screen  43 . The discharge roller  42  is provided at the outlet of the cloth hopper  41  to drive the color material to fall onto the surface of the slab material of the conveyor belt, so that the screen  43  is disposed below the discharge roller  42 , and the control system drives the discharge roller  42  to rotate. 
     The application color material assembly  4  is fixed on the frame  3 , and the slab is continuously driven by the conveyor belt. When the slab material moves to the application color material assembly  4 , the control system drives the discharge roller  42  and the fabric to rotate. The color material in the hopper  41  is carried out by the discharge roller  42  to provide a natural fall to the surface of the slab material to apply the color material. The natural falling of powdered material provides a sprinkling effect. 
     The color application member  4  can apply at least one layer of color on the entire surface of the slab. The screen  43  provided below the discharge roller  42  filters the color material in the final step to ensure that there are no large lumps of color material sprayed onto the slab material to ensure the cloth effect. 
     Another corresponding arrangement method of applying coloring material components is shown in a second embodiment of applying coloring material components, which adopts a matrix dusting method, as shown in  FIG. 6  and  FIG. 7 , which are arranged in the conveyance. On the conveying path of the belt, there is a color spray head  442  and a storage barrel  44 . The inside of the storage barrel  44  is divided into spray head rows  441  arranged in relatively independent interval sections along the width direction of the conveyor belt, and the color spray head  442  is disposed at the bottom of the interval sections of the spray head rows  441 , and the control system adjusts the opening and closing of the on-off control valve of the toner nozzle  442 . The interval sections of the spray head rows  441  form an array of spray heads. 
     The dosing color component  4  is fixed on the frame  3 , and the slab is continuously driven by the conveyor belt. When the slab moves to the color component  4  for color application, the control system drives the switch control valve of the color spray head  442  to open. The color material in the storage tank  44  naturally falls to the surface of the slab material through the color material spray head  442  to apply the color material. 
     The interval section  441  of the storage barrel  44  of the applied color material assembly  4  can be placed with different colors or different types of colorants. A plurality of colorant spray heads  442  are respectively arranged in the plurality of interval sections of the spray head rows  441  and are arranged along the lateral direction of the belt conveyor. This arrangement can ensure that the color material is covered in the width direction of the slab material, and each fixed nozzle is arranged below the storage barrel  44  to ensure that the material in the storage barrel  44  can be sprayed out. 
     As shown in  FIGS. 1 and 2 , in this embodiment, the pressing assembly  5  includes a cloth belt  53  for flattening and retaining the flour like powdered stone quartz. The powdered stone quartz has the consistency of flour dough. The pressing assembly  5  has a rolling belt  54  for dropping the stone powder and a conveyor belt  55  for feeding the rolling belt  54 . The cloth belt  53  and rolling belt  54  can share a common drive motor so that they are commonly powered and controlled synchronously with the conveyor belt  55 . The rolling belt  54  is provided under the cloth belt  53 , and they can be overlapped with each other. 
     The conveyor belt  55  can be linearly reciprocated above the cloth platform, and during its movement, the rolling belt  54  can push and squeeze the powdered stone quartz onto the cloth platform. After enough material is stored on the cloth belt  53 , the conveyor belt  55  moves the cloth belt  53  and the rolling belt  54  forward over the cloth platform. The cloth belt  53  is transported forward, and the rubbery material on it falls onto the rolling belt  54 , and the roller belt  54  is transported forward, so that the rubbery material obtained on it falls into the mold on the cloth platform. 
     A height difference between the roller belt  54  and the cloth platform can be adjusted so that the roller belt  54  pushes and squeezes the powdered stone quartz during the distribution process, so that the powdered stone quartz continuously squeezes toward and against the side wall of the mold. The gap between the powdered stone quartz mass is eliminated and the mortar like material around the mold is extruded. The two previously separate processes of fabric and blank forming in the prior art are now completed in a single step together to improve work efficiency and avoid multiple blank transfer process iterations, thereby improving the quality of slab blank forming. 
     Example 2 
     As shown in  FIG. 3 , in this embodiment, the coloring component  4  for color application and the stirring component  2  may be set at the same station. In this embodiment, the process of applying color material and stirring are completed at the same station, and the compaction assembly can also be set at the same station, or can be set relatively independently at another station, reducing the slab material in transfer steps between different processes, thus saving time. Although the slabs move along the assembly line conveyor belt, the 
     One of the corresponding setting methods of the application coloring material component of the present embodiment (that is, the third embodiment of the application coloring material component) is carried out by using the XYZ axis moving dusting method, which is provided on the moving component  1 , and is moved by the moving assembly  1  together with the agitating assembly  2 . The distributing coloring component  4  includes a coloring material spraying head and a coloring material bucket  47 , and the coloring material spraying head communicates with the coloring material through a conveying pipe by which the barrel  47  is in communication. 
     Another corresponding setting method of the application coloring material component of this embodiment (i.e., the fourth implementation type of the application coloring material component) is also carried out by using the XYZ axis moving dusting method, as shown in  FIGS. 8 and 9 . The pressing material assembly  5 , the application coloring material assembly  4  and the agitating assembly  2  are arranged on the frame  3 , and the coloring component  4  comprises a coloring material spraying head, a coloring material pump and a color storage material barrel  47 , and the coloring material spraying head is arranged. In the moving assembly  1 , the color storage barrel  47  is independently provided on one side of the frame  3 , and the color is provided on the conveying pipe between the color storage barrel  47  and the color spray head material pump. 
     The storage barrel  47  does not move with the moving sprinkler, which can reduce the weight of the moving frame  45  and its motion inertia, and improve the positioning accuracy when the mobile sprinkler starts and stops, or when it turns. 
     In this embodiment, the interlayer mixing device is provided on the frame  3 , and the frame  3  is provided with a platform to receive the slab material. As shown in  FIG. 3 , the pressing assembly  5  is slidably arranged on the frame  3  along the conveying direction of the slab, and includes a pressing roller  51  and a rotating base  52 . The length direction is perpendicular to the conveying direction of the slab material, and both ends thereof are rotatably disposed on the rotating base  52 . The rotating base  52  is disposed on the frame  3  through the wheel body, so that the pressing assembly  5  can move along the frame  3 . When the slab material is transported in a sliding direction, the nip roller  51  squeezes and rolls from the end surface of the slab material. 
     The pressure roller  51  is arranged above the conveyor belt parallel to the conveyor belt. During the process of the conveyor belt entering the working area of the stirring assembly  2  with the conveyor belt, the pressing force is applied by the pressure roller under the pressure roller  51 . The height of the press roller in the vertical direction can be adjusted to meet the processing of different thicknesses of slabs. 
     Furthermore, as shown in  FIG. 3 , the moving component  1  is an XYZ three-axis driving device, which can drive the stirring component  2  to make a straight line in the three directions of the X axis, the Y axis, and the Z axis relative to the frame  3  in reciprocating motion. The XYZ three-axis drive device is electrically connected to the control system. The stirring assembly  2  includes a stirring blade  21  and a driving device  22 . The driving device  22  can drive the stirring blade  21  to rotate in a vertical plane. 
     In this embodiment, the moving assembly  1  is a driving device with degrees of freedom in the three directions of the X axis, the Y axis, and the Z axis. Any conventional structure that can carry the stirring assembly  2  in a linear reciprocating motion in the above three directions should suffice. Within the scope of protection of the present invention, such conventional structures include various forms of structures composed of one or more combinations of conventional equipment such as motors, cylinders, gear racks, slide rail sliders, cams, sprockets, screw rods, etc. A specific embodiment of the moving assembly  1  is, as shown in  FIG. 10 , including a carriage  11 , an X-direction drive member, a Y-direction drive member, a Z-direction drive member and a spindle mounting plate  12 . An X-direction drive member, a Y-direction drive and a Z-direction drive are electrically connected to the control system. The X-direction drive drives the carriage  11  to reciprocate linearly in the X direction relative to the frame  3 , and the stirring assembly  2  is set through the spindle mounting plate  12 . In the traveling frame  11 , the Y-direction driving member drives the spindle mounting plate  12  to reciprocate linearly in the Y direction relative to the frame  3 . The stirring assembly  2  is provided on the spindle mounting plate  12  through the Z-direction driving element up and driven by the Z-direction drive to make a linear reciprocating movement in the Z-axis direction. 
     Further, the X-direction drive member and the Y-direction drive member are both structures including a drive reducer  13 , a drive gear  14  and a drive rack  15 . The drive rack  15  in the X-direction drive member is provided on the frame  3  and extended along the X-axis direction. The drive reducer  13  and the drive gear  14  are mounted on the carriage  11 . The drive reducer  13  drives the drive gear  14  to rotate and reciprocates along the drive rack  15  in a straight line. The driving rack  15  is provided on the traveling frame  11  and extends along the Y-axis direction, and the driving reducer  13  and the driving gear  14  are mounted on the spindle mounting plate  12 . The driving reducer  13  drives the driving gear  14  to rotate and along the driving rack  15  to make a linear reciprocating motion. 
     The Z-direction drive is a Z-direction drive reducer  16 , a screw assembly  17  and a Z-direction mounting plate  18 . The stirring assembly  2  is provided on the Z-direction mounting plate  18 . The Z-direction mounting plate  18  is fixedly connected to the nut of the screw assembly. The screw of the rod assembly  17  is rotatably provided on the spindle mounting plate  12 , and extends along the direction of the Z axis, and rotates under the drive of the Z-direction drive reducer  16 . The screw assembly  17  is used to achieve moving position fine adjustment and precise positioning. Further, a fast moving mechanism  19  is provided above the spindle mounting plate  12 , and the fast moving mechanism  19  can drive the stirring assembly  2  to move up and down in the vertical direction quickly, that is, when the stirring spindle  222  is not in operation, the stirring assembly  2  is carried for quickly rising and resetting. When working, the stirring assembly  2  can be quickly lowered to a position close to the processing surface, and then the spindle mounting plate  12  can be lowered through the Z-direction driving member, so that the stirring blade  21  falls accurately to the processing position, and the processing efficiency and precision are improved. The fast-moving mechanism  19  here may be one or more of mechanical structures such as cylinders, cylinders, gears, cams, sprockets and so on. 
     Preferably, the driving gear  14  and the driving rack  15  here are helical gear racks, and the tooth overlap of the helical gear rack is large, which reduces the force of each tooth, making the driving gear  14  and the driving rack  15  more durable and transmission more stable with low noise. In order to further improve the stability of the movement in all directions, between the walking frame  11  and the frame  3 , before the walking frame  11  and the spindle mounting plate  12 , the linear guide slider assembly  191  is provided at the position where the two are in contact with each other. The linear guide rail has low frictional resistance to movement, wear and tear for a long time, and good accuracy. 
     The agitating component  2  applies at least one layer of color material on the surface, or works on the plate material applying at least one layer of color material at a corresponding position on the surface of the plate material according to the design path of the final product texture. The slab is placed horizontally, and the driving device  22  drives the stirring blade  21  to rotate in a vertical plane. When passing through the slab, the raw material mixture of the color material and the slab are stirred with a tangential force. The depth of the stirring may involve the entire slab thickness. There is a color difference between the agitated position and the non-agitated position after agitation, which after agitation causes the color material to penetrate into the raw material mixture of the slab. After the texture processing and subsequent curing, pressing, and thickness setting are completed, the plate surface of the material leaves a transparent texture effect. 
     The material mixture of the color material and the slab material is stirred with a tangential force. Compared with the stirring of the color material and the material mixture by the rotation force perpendicular to the plate material, this technical solution can obtain a finer stirring path. The stirring path obtained by tangential force stirring is the thickness of the tool itself, and if the rotation force obtained by using the rotation force perpendicular to the slab is twice the width of the tool, no matter how the width of the tool is adjusted. There is a process of obtaining a fine texture. Above, the solution of the present invention has outstanding advantages, and from the perspective of actual use, it is impossible for the stirring blade  21  to be made too thin in order to obtain a fine texture. Here, too thin means that the strength of the blade itself is reduced, and stirring has a certain adhesion. When the raw material mixture is mixed, problems such as breakage are extremely easy to occur. 
     As shown in  FIGS. 11, 12 and 13 , the drive device  22  includes a spindle drive motor  221 , a stirring spindle  222 , a spindle reducer  223 , a hollow rotary table  224  and a C-axis motor  225 . The spindle drive motor  221  drives the stirring spindle  222  rotation. The stirring spindle  222  passes through the hollow rotary table  224  and drives the output shaft of the spindle reducer  223  to rotate. The output shaft of the spindle reducer  223  is arranged horizontally and horizontally, and it drives the stirring blade  21  to rotate in a vertical plane. The C-axis motor  225  is disposed on one side of the stirring spindle  222 , and its output shaft can drive the spindle reducer  223  to rotate relative to the stirring spindle  222 . From a top view, this would allow drawing of curves and arcs because the Z axis is the vertical axis for determining a height, and thus the C axis is the rotational axis about the Z axis. 
     The stirring blade  21  follows the spindle reducer  223  and rotates relative to the stirring spindle  222 . The stirring blade  21  is driven by a spindle drive motor  221 , a stirring spindle  222  and a spindle reducer  223 . The stirring blade  21  could be mounted on a chuck for easy replacement. The output shaft of the spindle reducer  223  is arranged horizontally and horizontally, driving the stirring blade  21  to rotate horizontally, and the horizontal rotating stirring blade  21  to the plate. During the texture mixing process, the horizontal rotating stirring blade  21  can lift the agitated material upward, and then lift it back to the position of the mixing texture. At the same time, it also acts as a filler to ensure that the agitated texture position will not cause the density of the board to be reduced or small hole defects due to lack of material. The moving trajectory of the stirring blade  21  is determined according to the set texture path. When moving to the corner of the path, the C-axis motor  225  drives the hollow rotary table  224  to rotate through an angle. The angle of rotation is determined by the turning angle of the preset path. The rotation of the rotary table  224  drives the stirring blade  21  to follow rotation, ensuring that the cutting direction of the stirring blade  21  can preferably be always kept in the tangent direction with the moving track when turning, so that the path angle of the path cut by the stirring transition is smooth, if such a smooth design is desired. 
     As shown in  FIGS. 14 and 15 , the stirring blade  21  includes a blade bar  211  and a blade body  212 . The blade bar  211  and a plurality of blade bodies  212  are combined into a fully detachable petal structure. The blade bar  211  is located at the center of the petal structure, and the other end extends outward in a direction perpendicular to the end surface of the blade body  212 . The end of the blade body  212  extends from the center of the petal structure and extends outwardly. By replacing the blade body  212  and blade bar  211  of different specifications, a blade with a petal structure of various diameters can be assembled to meet the stirring needs of various texture effects. The blade body  212  is planar and all the end surfaces of the blade body  212  are in the same plane. The middle portion of the blade body  212  is detachably attached to one end of the cutter bar  211  by connectors such as bolts. The free end of the cutter body  212  is bent toward the side away from the cutter bar  211  to form a bent portion  2110 . 
     The blade body  212  is flat and in the shape of a plane. The end surfaces of all the blade bodies  212  are in the same plane. A fine texture range can be cut when stirring and cutting the slab. In addition, the blade body  212  can also be made into an end bend (that is the free end of the blade body  212  is provided with a bent portion  2110 ), so that a larger texture range can be stirred. 
     As shown in  FIG. 16 , the blade body  212  is in a flat shape, all the end surfaces of the blade body  212  are parallel to the extending direction of the blade bar  211 , and one end of the blade body  212  is detachably inserted into the blade at the outer side wall of the rod blade bar  211 . The blade body  212  is a rectangular slab or a wedge-shaped slab or a slab whose outer contour is composed of a spiral curve. 
     As shown in  FIG. 11 , a scraper blade  231  is provided on the rear side of the stirring blade  21 , and the back scraper  23  is provided at the front end of the spindle reducer  223 , and its plate surface is perpendicular to the stirring plane of rotation of the blade  21 . During the lifting and falling process of the stirring blade  21 , some materials will be scattered outside the setting range of the texture stripes. By setting the material return scraper  23  on the rear side of the stirring blade  21 , the material will be scattered. In the setting range of the outer material backfilling into the texture stripes, the height between the material return scraper  23  and the end surface of the material can be an adjustable structure. By adjusting the height of the material return scraper  23 , the amount of material backfilling is controlled to improve efficiency. 
     The return scraper  23  is an angular structure composed of a scraper blade  231  and a fixed plate  232 . The fixed plate  232  is disposed on the spindle speed reducer  223  so that the scraper blade  231  is located on the stirring blade  21  rear side. The structure is simple, easy to install and use. 
     The height position of the return scraper  23  on the spindle speed reducer  223  is adjustable. The method for adjusting the height in this embodiment may be to provide a plurality of buckling positions in the height direction, and the return scraper  23  may be fixed to different buckling positions to achieve height adjustment, or may be through a rack and pinion. The adjustment methods involved in automatic accessories such as motors or cylinders, such as slider rails, that is, height adjustment structures commonly used by those skilled in the art should fall within the protection scope of the present invention.
