A stuffed food forming method, comprising a first step: feeding and cutting a wrapper, wherein a forming mold (1001) on a turntable is located below a wrapper feeding and cutting station (20), and after a dumpling wrapper is cut into a wrapper of a designated shape, the same falls onto the forming mold below, and a cut residual wrapper enters an opening (106) on the turntable and is conveyed downwards, achieving the recycling of residual wrappers; a second step: stuffing injection, wherein the turntable drives the forming mold that has received the wrapper to rotate to a stuffing filling station (30), stuffing being injected into the wrapper. The stuffed food forming method implements the recycling of residual wrappers on the basis of an existing structure by means of providing an opening structure, which is used for recycling cut residual wrappers, on the turntable assembly, thus fully using the space below the turntable assembly, while the residual wrappers may be directly stored or reused after processing by means of providing a recycling bin or a residual wrapper processing mechanism below the opening structure. In addition, the foregoing structure does not increase the area occupied by the whole device, solving the problem wherein the whole device cannot be further reduced in size due to residual wrapper processing requiring extra space.
A: A pull-tab rivet forming method comprises the following three steps: step 1, performing a pressing operation on a material belt (9) to form a crown-shaped spherical portion (10); step 2, continuing to perform a pressing operation on the spherical portion to form a hemispherical portion (11); and step 3, performing a reverse drawing operation on the hemispherical portion to form a cylindrical rivet (12). Also provided is a pull-tab rivet forming mold comprising an upper mold half (1) and a lower mold half (2). Three working positions spaced at equal intervals are arranged at the forming mold. The first working position is a spherical portion pressing working position. The second working position is a hemispherical portion pressing working position. The third working position is a rivet reverse drawing working position. The above forming method and mold divide a rivet forming process into three steps. A crown-shaped spherical portion and a hemispherical portion are sequentially formed in two steps, and then the hemispherical portion is reversely drawn to form a rivet, thereby ensuring a certain height of the drawn rivet, providing a formed rivet of high quality, and preventing occurrence of cracks and paint peel on a rivet surface.
B: A semi-finished food product angle adjustment method, fixing a fixing apparatus at a first work station (M1) position to a first corner of a wrapper (901), and driving the fixing apparatus by means of a motion driving assembly to move to a second work station (M2), thereby dragging the wrapper (901); in the process of dragging the wrapper (901), driving the fixing apparatus to rotate by means of a rotation driving assembly; also disclosed is a semi-finished food product angle adjustment mechanism used to implement the described angle adjustment method. The present semi-finished food product angle adjustment method and angle adjustment mechanism can adjust a rotation angle of a semi-finished food product, enabling a first corner of a wrapper to be rotated to an indicated angle, thereby facilitating subsequent processing steps; accuracy of wrapper rotation angle adjustment is high, and angle adjustment mechanism operation is stable, which can, as much as possible, prevent wrapper breakage, and prevent a filling of the wrapper from being thrown out.
C: Disclosed is a disc rotary brick press, comprising a rotary disc and a plurality of molds disposed on the rotary disc; the brick press further comprises a controller, a rotary driving mechanism that drives the rotary disc, a material spreading mechanism that spreads out a raw material, a pre-pressing mechanism that performs pre-pressing on the raw material, a main pressing mechanism that performs main pressing on the raw material, a demolding mechanism that demolds a molded brick, a main shaft mechanism that is located at the center of the rotary disc, and a main carrying frame that carries the material spreading mechanism, the pre-pressing mechanism, the main pressing mechanism, and the demolding mechanism. After using the described structure, and in comparison to the prior art, the present invention uses a rotary driving mechanism to drive a rotary disc to carry out intermittent circumferential rotation and drives a mold on the rotary disc to sequentially pass through a raw material feeding device, a material spreading mechanism, a pre-pressing mechanism, a main pressing mechanism and a demolding mechanism, so as to complete the pressing and molding of a raw material, thus achieving the mechanical automatic production of a brick, and greatly improving the production efficiency and production.
D: A multiple work position silicone piece multicolor molding machine, comprising a machine frame (10), a turntable (20), a first driving device, multiple second driving devices (30), multiple discharging nozzles (40), and a control device (50). Multiple work positions (21) are provided at intervals on the turntable (20). The first driving device drives the turntable (20) to rotate. The multiple discharging nozzles (40) are provided as vertically movable on the machine frame (10). The multiple discharging nozzles (40) are in a circumferential arrangement and arranged directly above the turntable (20). The multiple second driving devices (30) respectively drive the corresponding discharging nozzles (40) to move up and down. With the multiple color-forming discharging nozzles (40) provided on same machine frame (10), the turntable (20) provided below the discharging nozzles (40), the multiple work positions (21) provided on the turntable (20), and silicone strip molds placed on the work positions (21), when a silicone strip finishes with one color below the first discharging nozzle (40), the turntable (20) rotates to below another discharging nozzle (40), the silicone strip finishes the application of a second color and as such finishes the application of various colors, compared with the past in which one machine could only finish the application of one color, the molding machine can finish the application of various colors, thus increasing production efficiency and saving on footprint.
