       BACKGROUND OF THE INVENTION 
       [0002]    1. Technical Field 
         [0003]    The present invention relates to the manufacture of cleaning sheets (such as sheet products for laundry washing, hand washing, cookware and tableware cleaning, showering, bathing, disinfecting, and pesticide removal from fruits and vegetables). More particularly, the present invention relates to an intelligent manufacturing system for making cleaning sheets. 
         [0004]    2. Description of Related Art 
         [0005]    Cleaning sheet products, such as laundry detergent sheets, are gaining popularity among consumers because they are compact, portable, easy to store, and easy to use with precise amount control. 
         [0006]    However, there is only one kind of cleaning sheet product, i.e., laundry detergent sheets, currently available in the domestic market. Furthermore, the existing laundry detergent sheet products often fall short in terms of their cleaning power. Such issue is not only related to the composition or formula of the detergent sheets, but also to the manufacturing process. 
         [0007]    To address such issue, the present inventor has invented an intelligent manufacturing system for making cleaning sheets. The manufacturing system has improved productivity, and the manufactured sheets has greater cleaning power. 
       SUMMARY OF THE INVENTION 
       [0008]    The present invention provides an intelligent manufacturing system for making cleaning sheets. The system is designed to significantly improve the cleaning power of the cleaning sheets over the prior art. The solution for solving the technical problem of the prior art includes the following. 
         [0009]    The intelligent manufacturing system for making cleaning sheets is characterized in that it comprises a drying apparatus and a continuous track provided with a non-stick coating. 
         [0010]    Wherein, the drying apparatus includes at least two stages and a lifting roller is arranged between the two stages of the drying apparatus. 
         [0011]    The drying apparatus includes an intelligent microwave heating system equipped with a vapor-extraction mechanism, or includes an oven, or includes a fan heater, or includes a fin-type heater, or includes a tube-type heater. 
         [0012]    Preferably, the intelligent microwave heating system of the present invention includes a plurality of modularized microwave heating devices that are configured to be combined freely to form the two stages of the drying apparatus. Each said stage formed by the microwave heating devices has two ends thereof provided with microwave hoods. The lifting roller is disposed between two adjacent said microwave hoods. 
         [0013]    Each said microwave heating device includes a material sensor. The material sensor is in communicatory connection with an intelligent controller that controls the overall operation of the system. The intelligent controller is installed on a track frame that supports the continuous track, or is separated from the track frame, or is installed on the drying apparatus. The intelligent controller is in the form of a handheld intelligent terminal, such as a handset, or is in the form of a personal computer (PC). 
         [0014]    The continuous track passes through the drying apparatus, or travels below the drying apparatus, or travels above the drying apparatus, or travels along one side of the drying apparatus. Preferably, the continuous track passes through the two-stage, modularized microwave heating device. 
         [0015]    The non-stick coating is preferably made of Teflon so as to effectively prevent the material of the cleaning sheet from sticking on the continuous track. The non-stick coating and the continuous track are integrated as a unity, or the non-stick coating is applied to the exterior surface of the continuous track, or the non-stick coating is applied to a medium that is fixed to the exterior surface of the continuous track. Preferably, the medium is heat-resistant non-woven cloth. 
         [0016]    The continuous track has one end thereof provided with a material-feeding apparatus for feeding a material for making the cleaning sheet onto the continuous track. The material-feeding apparatus is freely separated from the track frame or is fixedly installed on the track frame. 
         [0017]    A thickness adjustor is provided above the continuous track for adjusting the thickness of the raw material for making the cleaning sheet on the continuous track. The thickness adjustor is fixedly installed on the track frame, or is suspended over the continuous track, or is in the form of a handheld device. 
         [0018]    A rolling-up apparatus is also provided at one side of the continuous track or above the continuous track for rolling the cleaning sheet that has been dried. The rolling-up apparatus is freely separated from the track frame, or is fixedly installed on the track frame, so as to roll the dried cleaning sheet into rolls for easy storage and transportation. 
         [0019]    There is further an enzyme-adding apparatus that is provided at one side of the continuous track or above the continuous track for adding active ingredients to the cleaning sheet blank that has been dried. The enzyme-adding apparatus is installed on the track frame, or is suspended over the continuous track, or is arranged at one side of the track frame and is freely separated from it. 
         [0020]    There is further an embossing apparatus that is provided at one side of the continuous track or above the continuous track for embossing the cleaning sheet blank with patterns. The embossing apparatus is installed on the track frame, or is suspended over the continuous track, or is arranged at one side of the track frame and freely separated from it. 
         [0021]    There is further a cutting apparatus that is provided at one side of the continuous track or above the continuous track for cutting the cleaning sheet that has been dried into smaller pieces with predetermined shapes. The cutting apparatus is installed on the track frame, or is suspended over the continuous track, or is freely separated from the track frame, so as to cut the large cleaning sheet or roll into small pieces with various desired shapes for convenient packaging. 
         [0022]    There is further a collecting apparatus that is provided at one end or one side of the continuous track for collecting the pieces of cleaning sheets that have been cut by the cutting apparatus. The collecting apparatus is freely separated from the track frame, or is fixedly installed at one end of the track frame. 
         [0023]    The present invention provides the following beneficial effects. The continuous track is at its exterior surface coated with non-stick coating or covered by a medium having non-stick coating, so that the manufactured cleaning sheet can have active cleaning ingredients therein protected, and can be easily taken off from the continuous track after being dried. 
         [0024]    In addition, the lifting roller between the two stages of the drying apparatus prevents adhesion between successive layers of the rolled cleaning sheets. Also, the enzyme-adding apparatus that sprays active enzyme onto the dried cleaning sheet effectively retains the activity of the enzyme.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0042]    The following specific embodiments are to further illustrate the technical design, features, objects and effects of the present invention. 
         [0043]    The first embodiment of the present invention is illustrated below with reference to  FIGS. 1-10 . 
         [0044]    The intelligent manufacturing system includes a cleaning sheet production line  1  (referring to  FIG. 1 ). The cleaning sheet production line  1  includes a continuous track  2 , a track frame  21  that supports the continuous track  2 , a material-feeding apparatus  3  that adds a source material for the cleaning sheet (which can be a liquid, such as a high concentration liquid detergent) onto the continuous track  2 , a thickness adjustor  4  that adjusts the thickness of the material of the cleaning sheet on the continuous track  2 , a two-stage drying apparatus  5  that vaporizes moisture from the material of the cleaning sheet on the continuous track  2 , a lifting roller  6  that is arranged between the two stages of the drying apparatus  5 , a rolling-up apparatus  7  that rolls the dried cleaning sheet into rolls, and an intelligent controller  8  that controls the overall operation. 
         [0045]    Therein, the continuous track  2  is provided with non-stick coating  22  (as shown in  FIG. 2 ). The non-stick coating  22  is preferably made of Teflon for effectively preventing the material for making the cleaning sheet from sticking on the continuous track  2 . The non-stick coating  22  can be integrated into the continuous track  2 . Alternatively, the non-stick coating  22  is applied to the exterior surface of the continuous track  2 . Alternatively, the non-stick coating  22  is applied to a medium  23  that is fixed to the exterior surface of the continuous track  2 . The medium  23  is preferably a heat-resistant non-woven cloth. The continuous track  2  is driven by a motor M 1  that is installed on the track frame  21 . The start, rotation rate and stop of the motor M 1  are all intelligently controlled by the intelligent controller  8 . 
         [0046]    The material-feeding apparatus  3  is freely separated from the track frame  21 , or is fixedly installed on the track frame  21 . The material-feeding apparatus  3  (as shown in  FIGS. 3A and 3B ) includes a hopper brace  31  and a feeding hopper  32  that is installed on the hopper brace  31 . A dip adjustor  33  may be provided at the bottom of the feeding hopper  32  for adjust the inclining angle of the feeding hopper  32 . To make the source material spread evenly and move with an even front on the surface of the continuous track  2 , one or more equalizer bars  34  may be provided on the feeding hopper  32 . 
         [0047]    The thickness adjustor  4  is fixedly installed on the track frame  21 .

         [0048]    The drying apparatus  5  includes an intelligent microwave heating system  51  equipped with a vapor-extraction mechanism  501  (as shown in  FIG. 4 ), or includes intelligent oven  52  (as shown in  FIG. 5 ), or includes a fan heater  53  (as shown in  FIG. 6 ), or includes a fin-type heater  54  (as shown in  FIG. 7 ), or includes a tube-type heater  55  (as shown in  FIG. 8 ). 
         [0049]    Where the drying apparatus  5  is the intelligent microwave heating system  51 , or the intelligent oven  52 , or the tube-type heater  55 , the continuous track  2  passes through drying apparatus  5 . Where the drying apparatus  5  is the fin-type heater  54 , the continuous track  2  is arranged below, above or through the drying apparatus  5 . Where the drying apparatus  5  is the fan heater  53 , the continuous track  2  is arranged along either or both sides of the drying apparatus  5 . 
         [0050]    In the present embodiment, the drying apparatus  5  is preferably the intelligent microwave heating system  51  (as shown in  FIG. 4 ). The intelligent microwave heating system  51  includes a plurality of modularized microwave heating devices  511  that that are configured to be combined freely to form the two stages, namely an upstream stage and a downstream stage. The microwave heating device  511  further has a sensor  512  for sensing the presence of material on the continuous track  2 . The sensor  512  is in communicatory connection with the intelligent controller  8 , for accurately controlling the on and off status of each of the microwave heating devices  511 , so as to save energy while effectively protecting the continuous track  2  from prematurely receiving high heat, thereby prolonging the service life of the continuous track  2 . Additionally, each of the stages formed by the microwave heating devices  511  has two ends thereof provided with microwave hoods  513 . The lifting roller  6  is arranged between the two adjacent microwave hoods  513 . 
         [0051]    The lifting roller  6  (as shown in  FIG. 9 ) is mounted on a roller brace  61 . The roller brace  61  is installed on the track frame  21 , or is placed on the ground and is freely separated from the track frame  21 . A motor M 2  for driving the lifting roller  6  to rotate is also installed on the roller brace  61 . The start, rotation rate and stop of the motor M 2  are all intelligently controlled by the intelligent controller  8 , or are controlled manually. 
         [0052]    The rolling-up apparatus  7  (as the enlarged view C shown in  FIG. 10 ) includes a roller support  71 , and a rolling-up roller  72  that is installed on the roller support  71 . A motor M 3  installed on the roller support  71  drives the rolling-up roller  72  to rotate and its operation is accurately controlled by the intelligent controller  8 . 
         [0053]    The intelligent controller  8  is freely separated from the track frame  21 , or is installed on the track frame  21 , or is installed on the drying apparatus  5 . Alternatively, the intelligent controller  8  is a handheld intelligent terminal such as a handset, or the intelligent controller  8  is a PC such as a computer. 
         [0054]    The operations and work flow of the intelligent manufacturing system for making cleaning sheet according to the first embodiment is described below. 
         [0055]    The values of output power for the motors M 1 , M 2  and M 3  in the intelligent controller  8  are first set such that the three motors will rotate at the same speed, thereby preventing differential rotation that would cause the dried cleaning sheet to break and unable to form rolls. The temperature for the drying apparatus  5  is also set. 
         [0056]    The material-feeding apparatus  3  is then moved to one end of the continuous track  2  and the feeding hopper  32  is positioned to contact the continuous track  2 . The source material of the cleaning sheet is poured into the feeding hopper  32 , and the continuous track  2  is started. 
         [0057]    For the upstream stage of the intelligent microwave heating system  51  which includes a plurality of microwave heating devices  511 , when the sensor  512  in the first microwave heating device  511  detects that the material for making the cleaning sheet on the continuous track  2  is about to enter the first microwave heating device  511 , the intelligent controller  8  activates the first microwave heating device  511  to provide heat for drying. When the sensor  512  in the second microwave heating device  511  detects the material on the continuous track  2  is about to enter the second microwave heating device  511 , the intelligent controller  8  activates the second microwave heating device  511  to provide heat for drying, and so on. 
         [0058]    When the sensor  512  in the last microwave heating device  511  of the upstream stage of the intelligent microwave heating system  51  detects that the cleaning sheet on the continuous track  2  is about to exit the last microwave heating device  511 , the intelligent controller  8  immediately starts the motor M 2 . The lifting roller  6 , driven by the motor M 2 , lifts the dried cleaning sheet that exits the upstream stage of the intelligent microwave heating system  51 , so that the surface of the cleaning sheet contacting the continuous track  2  can be dried rapidly by the ambient heat or by a fan. Afterwards, the cleaning sheet is carried by the continuous track  2  to enter the downstream stage of the intelligent microwave heating system  51  to be dried again. 
         [0059]    For the downstream stage of the intelligent microwave heating system  51  which includes at least one microwave heating device  511 , when the sensor  512  in the microwave heating device  511  detects that the cleaning sheet on the continuous track  2  is about to enter therein, the intelligent controller  8  immediately turns on the microwave heating device  511  in the downstream stage of the intelligent microwave heating system  51  to provide heat for drying. 
         [0060]    When the sensor  512  in the microwave heating device  511  of the downstream stage of the intelligent microwave heating system  51  detects that the cleaning sheet on the continuous track  2  is about to exit therefrom, the intelligent controller  8  immediately starts the motor M 3 , so that the rolling-up roller  72 , driven by the motor M 3 , rolls the dried cleaning sheet on the rolling-up roller  72 . When the cleaning sheet on the rolling-up roller  72  reaches a predetermined amount, the intelligent controller  8  suspends the continuous track  2 , the drying apparatus  5 , the lifting roller  6 , and the rolling-up roller  72 . After a replacement vacant rolling-up roller  72  is loaded, the manufacturing operations are resumed. 
         [0061]    The second embodiment of the present invention is illustrated below with reference to  FIGS. 11-16 . 
         [0062]    The system includes a cleaning sheet production line  1  (referring to  FIG. 11 ). The cleaning sheet production line  1  includes a continuous track  2 , a track frame  21  that supports the continuous track  2 , a material-feeding apparatus  3  that adds a source material of the cleaning sheet (which can be a liquid, such as highly concentration liquid detergent) onto the continuous track  2 , a thickness adjustor  4  that adjusts the thickness of the material of the cleaning sheet on the continuous track  2 , a two-stage drying apparatus  5  that vaporizes moisture from the material of the cleaning sheet on the continuous track  2 , a lifting roller  6  that is arranged between the two stages of the drying apparatus  5 , an enzyme-adding apparatus  9  that adds active ingredients to the dried cleaning sheet, an embossing apparatus  10  that embosses the cleaning sheet with patterns, a cutting apparatus  11  that cuts the dried cleaning sheet into predetermined shapes, a collecting apparatus  12  that collects the pieces of the cleaning sheet cut by the cutting apparatus  11 , and an intelligent controller  8  that controls the overall operation.

Alternatively, the non-stick coating  22  is applied to the exterior surface of the continuous track  2 , or the non-stick coating  22  is applied to a medium  23  that is fixed to the exterior surface of the continuous track  2 . The medium  23  is preferably a heat-resistant non-woven cloth. The continuous track  2  is driven by a motor M 1  that is installed on the track frame  21 . The start, rotation rate and stop of the motor M 1  are all controlled by the intelligent controller  8 . 
         [0064]    The material-feeding apparatus  3  is freely separated from the track frame  21 , or is fixedly installed on the track frame  21 .

The feeding member  302  has its outlet as wide as that of the continuous track  2 , or narrower than the continuous track  2 , so as to prevent the liquid source material for making the cleaning sheet being wasted by overflow. The feeding member  302  has therein more than one transverse equalizer bars  3021  for equalizing the cleaning sheet&#39;s liquid material. The transverse equalizer bars  3021  are arranged on one inner surface of the feeding member  302 , or arranged symmetrically on both inner surfaces of the feeding member  302 , or arranged in a staggered fashion on both inner surfaces of the feeding member  302 , so as to make the liquid material of the cleaning sheet flow out the outlet at a uniform speed while filling up the outlet and thereby distribute over the continuous track  2  evenly. 
         [0065]    The thickness adjustor  4  is fixedly installed on the track frame  21 .

The embossing apparatus  10  includes a moving arm  101  that is flexibly extendable and rotatable, a replaceable mold  102  that is installed on one end of the moving arm  101 , and a motor M 4  that drives the moving arm  101 . The motor M 4  is in communicatory connection with the intelligent controller  8  by a data cable or wirelessly, and is controlled by the intelligent controller  8 . The motor M 4  has its controller preloaded with a control program, or receives a control program wirelessly from a remote input device, or receives a control program through a USB interface, so that the moving arm  101  can perform various motions under control and thereby emboss the dried cleaning sheet with various patterns. 
         [0072]    The cutting apparatus  11  (as shown in  FIG. 15 ) is installed on the track frame  21 , or is suspended over the continuous track  2 , or is freely separated from the track frame  21 , so as to cut the formed whole piece of cleaning sheet or sheet roll into smaller pieces of any desired shapes for convenient packaging. The cutting apparatus  11  includes a tool arm  111  that is extendable and rotatable, a cutting knife  112  that is replaceably installed at one end of the tool arm  111 , and a motor M 5  that drives the tool arm  111  to work. The motor M 5  is in communicatory connection with the controller  8  by a data cable or wirelessly, and is controlled by the intelligent controller  8 . Similarly, the motor M 5  has its controller preloaded with a control program, or receives a control program wirelessly from a remote input device, or receives an control program through a USB interface, so that the tool arm  111  can perform various motions under control and thereby cut the tool arm  111  into pieces of various shapes. 
         [0073]    The collecting apparatus  12  (as shown in  FIG. 16 ) is freely separated from the track frame  21 , or is fixedly installed on one end of the track frame  21 . The collecting apparatus  12  includes a shovel  121  that picks up the cleaning sheet, a drop hopper  122  that put the cut pieces of the cleaning sheet into packaging bags, and a counter  123  that counts the number of the pieces being packed. Therein, the shovel  121  may be controlled manually. Alternatively, the shovel  121  is in communicatory connection with the controller  8  by means of a data cable or wirelessly, and is controlled by the intelligent controller  8 . 
         [0074]    The intelligent controller  8  is freely separated from the track frame  21 , or is installed on the track frame  21 , or is installed on the drying apparatus  5 . Alternatively, the intelligent controller  8  is a handheld intelligent terminal such as a handset, or the intelligent controller  8  is a PC unit such as a computer. 
         [0075]    The operations and work flow of the intelligent manufacturing system for making cleaning sheet according to the second embodiment is described below. 
         [0076]    The values of output power for the motors M 1  and M 2  are first set in the intelligent controller  8  such that the two motors will rotate at the same speed, thereby preventing differential rotation that would cause the dried cleaning sheet to break. Also set is the temperature for the drying apparatus  5 . 
         [0077]    Then the material-feeding apparatus  3  is moved to one end of the continuous track  2  and the feeding hopper  32  is posed to contact the continuous track  2 . The material of the cleaning sheet is poured into the feeding hopper  32 , and the continuous track  2  is started. 
         [0078]    For the upstream stage of the intelligent microwave heating system  51  that includes a plurality of microwave heating devices  511 , when the sensor  512  in the first microwave heating device  511  detects that the material for making the cleaning sheet on the continuous track  2  is about to enter the first microwave heating device  511 , the intelligent controller  8  activates the first microwave heating device  511  to provide heat for drying. When the sensor  512  in the second microwave heating device  511  detects the material on the continuous track  2  is about to enter the second microwave heating device  511 , the intelligent controller  8  activates the second microwave heating device  511  to provide heat for drying, and so on. 
         [0079]    When the sensor  512  in the last microwave heating device  511  of the upstream stage of the intelligent microwave heating system  51  detects that the cleaning sheet on the continuous track  2  is about to exit the last microwave heating device  511 , the intelligent controller  8  starts the motor M 2 . The lifting roller  6 , driven by the motor M 2 , lifts the dried cleaning sheet that passes through the upstream stage of the intelligent microwave heating system  51 , so that the surface of the cleaning sheet contacting the continuous track  2  can be dried rapidly by the ambient heat or by a fan. Afterwards, the cleaning sheet is carried by the continuous track  2  to enter the downstream stage of the intelligent microwave heating system  51  to be dried again. 
         [0080]    For the downstream stage of the intelligent microwave heating system  51  which includes at least one microwave heating device  511 , when the sensor  512  in the microwave heating device  511  detects that the cleaning sheet on the continuous track  2  is about to enter therein, the intelligent controller  8  activates the microwave heating device  511  in the downstream stage of the intelligent microwave heating system  51  to provide heat for drying. 
         [0081]    When the cleaning sheet on the continuous track  2  leaves the microwave heating device  511  in the downstream stage of the intelligent microwave heating system  51 , the intelligent controller  8  immediately opens the solenoid valve  94  in the enzyme-adding apparatus  9 , and makes the sprayer  93  spray the active ingredients stored in the pressure vessel  91 , such as enzyme, evenly over the cleaning sheet. 
         [0082]    The continuous track  2  carries the enzyme-applied cleaning sheet forward, and the intelligent controller  8  controls the motor M 4  in the embossing apparatus  10  to drive the mold  102  to emboss the dried cleaning sheet with various patterns. 
         [0083]    The continuous track  2  carries the embossed cleaning sheet forward, and the intelligent controller  8  controls the motor M 5  in the cutting apparatus  11  to drive the cutting knife  112  to cut the cleaning sheet into smaller pieces of various shapes. 
         [0084]    The continuous track  2  carries the cut pieces of the cleaning sheet forward, and at the same time the shovel  121  of the collecting apparatus  12  collect the cut pieces and put them into the drop hopper  122  for subsequent packaging into boxed or bags. 
         [0085]    The second embodiment includes the following improvements. The cleaning sheet production line  1  (referring to  FIG. 11 ) includes two modules, the first module including the continuous track  2 , the track frame  21  that supports the continuous track  2 , the material-feeding apparatus  3  that feeds the source material for making the cleaning sheet onto the continuous track  2 , the thickness adjustor  4  that adjusts the thickness of the material on the continuous track  2 , a two-stage drying apparatus  5  that vaporizes moisture from the cleaning sheet&#39;s material on the continuous track  2 , the lifting roller  6  that is arranged between the two stages of the drying apparatus  5 , the enzyme-adding apparatus  9  that adds active ingredients to dried cleaning sheet, and the intelligent controller  8  that controls overall operation. 
         [0086]    The second module is composed of the embossing apparatus  10  that embosses the cleaning sheet with patterns, the cutting apparatus  11  that cut the dried cleaning sheet into pieces of various shapes, and the collecting apparatus  12  that receives the pieces of the cleaning sheet cut by the cutting apparatus  11 . 
         [0087]    The two modules can be freely separated by an arbitrary distance therebetween. The working principle and operation of the two modules are similar to those described for the second embodiment, and how they can be connected is apparent to people shilled in the art.
