[0039] When in use, the feed port of the diverting filling mechanism 2 is connected to the discharge port of the screw extruder, and the screw extruder delivers the raw material to the diverting filling mechanism 2, and then the diverting filling mechanism 2 divides the received raw material into several portions, and supplies the divided raw material to the forming mechanism 3, and each 3D forming mold 32 of the forming mechanism 3 receives a portion of the raw material, and the 3D forming mold 32 forms the raw material into a product of the required shape, and the opening and closing device drives the 3D forming mold 32 to open the mold and release the product to the conveying mechanism 4 for external output. Compared with the prior art, the present application can continuously produce food, improve production efficiency, and reduce costs.

[0040] like Figure 3-Figure 6 As shown together, along the moving direction of the raw material, the flow-dividing filling mechanism 2 includes a feed pipe 21, a distribution pipe 22 and a plurality of distributors 23 arranged in sequence, the feed pipe 21 is connected to the distribution pipe 22, the number of distributors 23 is equal to the number of 3D forming molds 32 and corresponds one to one, the distributor 23 is provided with a distributor feed port 235 and a distributor discharge port 236, the distributor feed port 235 is connected to the distribution pipe 33, and the distributor discharge port 236 is connected to the feed port of the 3D forming mold 32. Among them, the feed pipe 21 is a three-way Y-shaped pipe, one port is connected to the screw extruder, and the other two ports are connected to the distribution pipe 22, and the raw materials from the screw extruder are evenly distributed in the distribution pipe 22.

[0041] The distributor 23 includes a housing 231 fixed on the frame 1, a stator 232 fixed in the housing 231, and a rotor 233 located in the stator 232 and adapted to the stator 232. The rotor 233 is provided with two cross-arranged blades 234, and the blades 234 can slide on the rotor 233. The two blades 234 are respectively provided with avoidance gaps to avoid movement interference. The distributor feed port 235 and the distributor discharge port 236 are respectively provided on the housing 231 and communicate with the inner cavity of the stator 232.

[0042] When the distributor 23 supplies raw materials to the 3D molding die, the raw materials from the screw extruder push the rotor 233 to move in the stator 232, the rotor 233 is tangent to the stator 232, the ends of the two blades 234 are always in contact with the inner surface of the rotor 233, the rotor 233, the blades 234 and the stator 232 form a closed distribution cavity, along the movement direction of the rotor 233, at the distributor feed port 235, the volume of the distribution cavity gradually increases, the raw materials are continuously filled into the distribution cavity, at the distributor discharge port 236, the volume of the distribution cavity gradually decreases, and the raw materials in the distribution cavity are squeezed into the 3D molding die 32. The distributor discharge port 236 is connected to a discharge connector 230, and the discharge connector 230 is connected to the feed port of the 3D molding die 32 through a pipeline.

[0043] Furthermore, the position and movement of each rotor 233 are synchronized, and the position and movement of the corresponding blade 234 on each rotor 233 are synchronized, so that each distributor 23 can move synchronously. Accordingly, each 3D molding mold 32 can obtain raw materials at the same time, and each 3D molding mold 32 can release the product to the conveying mechanism 4 at the same time, thereby ensuring production consistency and improving production efficiency.

[0044] Each rotor 233 is connected by four rotor connecting rods 237, which penetrate all rotors 233 and connect all rotors 233 together, forcing each rotor 233 to have the same position and movement. Each stator 232 is connected by two stator connecting rods 238, which penetrate all stators 232, forcing each stator 232 to have the same position.

[0045] A positioning column 239 is provided between each stator 232 and the housing 231 for accurately positioning each stator 232 in the housing 231 .

[0046] like Figure 7-Figure 9 As shown together, the opening and closing device includes a motor 39, a lifting device, a card plate 33 and a guide device. The motor 39 drives the lifting device to rise and fall. The card plate 33 is installed at the lifting end of the lifting device. The card plate 33 is connected to the 3D molding mold 32, and the two ends of the card plate 33 are respectively connected to a guide device.

[0047] The lifting device is preferably a gear rack mechanism, which includes a gear 34 and a rack 35 meshing with the gear 34. The rack 35 is fixed on a guide rail 36. The guide rail 36 is fixedly connected to the clamping plate 33. Rotatable guide rollers 37 are respectively provided on both sides of the guide rail 36. The guide rollers 37 are used to constrain the guide rail 36.

[0048] The 3D molding mold 32 adopts an existing mature design. When the distributor 23 fills the raw material into the 3D molding mold 32 and compacts and shapes it in the 3D molding mold 32, the 3D molding mold 32 has a card slot connected to the card plate 33. When the card plate 33 moves upward, the 3D molding mold 32 opens to release the molded product onto the mesh bag conveyor.

[0049] A water nozzle 38 is provided at the product release portion of the 3D molding mold 32. When the product is released, the water nozzle 38 sprays water toward the product portion to assist in demoulding the product.

[0050] like Fig.10As shown, the conveying mechanism 4 includes a mesh belt conveyor, which includes a conveyor support 41 fixed on the frame 1 and a mesh belt arranged on the conveyor support. The conveyor support 41 is provided with a water tray 42, two front pressure plate assemblies 43 and two rear pressure plate assemblies 44. The two front pressure plate assemblies 43 are arranged on both sides of the mesh belt, and the rear pressure plate assemblies 44 are arranged on both sides of the mesh belt. The front pressure plate assemblies 43 and the rear pressure plate assemblies 44 are pressed on the mesh belt respectively. When the formed product is released onto the mesh belt, the mesh belt drives the product to move forward. Since the mesh belt is pressed downward by the front pressure plate assemblies 43 and the rear pressure plate assemblies 44, the mesh belt and the product are immersed in the water of the water tray 42 at the position between the front pressure plate assemblies 43 and the rear pressure plate assemblies 44. The water bath for the product can help the product to be formed and wash away the residual material on the product. The water nozzle 38 is located above the water tray 42, and the water sprayed by the water nozzle 38 falls into the water tray 42.

[0051] The water nozzle 38 is connected to the water outlet of the water pump 5. A filter box 45 is provided on one side of the water tray 42. The water outlet of the filter box 45 is connected to the water inlet of the water pump 5. The water in the water tray 42 flows back to the filter box 45, is filtered in the filter box 45, and then is transported to the water nozzle 38 by the water pump 5 to realize the recycling of water.
