Description

Technical Field

[0001] This invention relates to the field of food production equipment technology, and more specifically, to a 3D extrusion molding machine. Background Technology

[0002] Currently, the production of foods such as hamburger patties, chicken nuggets, mango mousse, and skinless sausages mostly relies on molds. The raw materials are first filled into the mold, then the mold is closed and compacted, and finally, the food is demolded to produce the desired shape. This molding method requires frequent filling, closing, and opening of the mold. Each mold can only produce a small amount of food at a time, and production is intermittent, resulting in low efficiency and high costs. Continuous production would significantly improve efficiency and reduce costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a 3D extrusion molding machine that can continuously produce food.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0005] A 3D extrusion molding machine includes: a frame, wherein the frame is provided with a diversion and filling mechanism, a molding mechanism and a conveying mechanism;

[0006] The diversion and filling mechanism is used to divide the received raw materials into several equal portions and supply the divided raw materials to the molding mechanism.

[0007] The molding mechanism has multiple 3D molding molds, each of which receives a portion of the equally divided raw material and molds the raw material into the desired product.

[0008] The conveying mechanism is used to output the product formed by the forming mechanism;

[0009] The molding mechanism includes a molding support, a 3D molding die disposed on the molding support, and an opening and closing device for driving all the 3D molding dies to open and close.

[0010] Preferably, along the direction of material movement, the diversion filling mechanism includes a feed pipe, a distribution pipe, and multiple distributors arranged sequentially. The feed pipe is connected to the distribution pipe, and the number of distributors is equal to and corresponds one-to-one with the number of 3D molding dies. Each distributor has a distributor inlet and a distributor outlet. The distributor inlet is connected to the distribution pipe, and the distributor outlet is connected to the feed inlet of the 3D molding die.

[0011] Preferably, the distributor includes a fixed housing, a stator fixed inside the housing, and a rotor located in the stator and adapted to the stator. The rotor is provided with two cross-shaped blades. The distributor inlet and the distributor outlet are respectively located on the housing and communicate with the inner cavity of the stator.

[0012] When the distributor supplies raw materials to the 3D molding die, the rotor is tangent to the stator, and the ends of the two blades are always in contact with the inner surface of the rotor. The rotor, the blades, and the stator surround the distribution cavity. Along the direction of movement of the rotor, the volume of the distribution cavity gradually increases at the feed inlet of the distributor and gradually decreases at the discharge outlet of the distributor.

[0013] Preferably, the position and movement of each rotor are synchronized, and the position and movement of the corresponding blades on each rotor are synchronized.

[0014] Preferably, each of the rotors is connected by a rotor link that extends through all of the rotors.

[0015] Preferably, each of the stators is connected by a stator link that passes through all the stators.

[0016] Preferably, the opening and closing device includes a motor, a lifting device, a clamping plate, and a guide device. The motor drives the lifting device to move up and down. The clamping plate is installed on the lifting end of the lifting device. The clamping plate is connected to the 3D molding mold. Both ends of the clamping plate are respectively connected to a guide device.

[0017] Preferably, each of the 3D molding dies is provided with a water spray nozzle at the product release point.

[0018] Preferably, the conveying mechanism includes a mesh belt conveyor, which includes a conveyor support and a mesh belt disposed on the conveyor support.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0034] like Figure 1 and Figure 2 As shown in the figure, a 3D extrusion molding machine has a frame 1, and the frame 1 is provided with a diversion filling mechanism 2, a molding mechanism 3 and a conveying mechanism 4;

[0035] The diversion and filling mechanism 2 is used to divide the received raw materials into several portions and supply the divided raw materials to the forming mechanism 3.

[0036] The molding mechanism 3 has multiple 3D molding molds 32. Each 3D molding mold 32 receives a portion of the evenly distributed raw material and molds the raw material into the desired product.

[0037] The conveying mechanism 4 is used to output the products formed by the forming mechanism 3;

[0038] The molding mechanism 3 includes a molding support 31 fixed on the frame 1, a 3D molding mold 32 disposed on the molding support 31, and an opening and closing device for driving all 3D molding molds 32 to open and close.

[0039] In use, the feed inlet of the diversion filling mechanism 2 is connected to the discharge outlet of the screw extruder. The screw extruder delivers raw materials to the diversion filling mechanism 2, which then divides the received raw materials into several portions and supplies the divided raw materials to the forming mechanism 3. Each 3D forming mold 32 of the forming mechanism 3 receives one portion of raw material and shapes the raw material into the desired product shape. The opening and closing device drives the 3D forming mold 32 to open and release the product onto the conveying mechanism 4 for external output. Compared with the prior art, this application can continuously produce food, improve production efficiency, and reduce costs.

[0040] like Figures 3-6 As shown, along the direction of material movement, the diversion and filling mechanism 2 includes a feed pipe 21, a distribution pipe 22, and multiple distributors 23 arranged sequentially. The feed pipe 21 is connected to the distribution pipe 22. The number of distributors 23 is equal to and corresponds one-to-one with the number of 3D molding dies 32. Each distributor 23 has a distributor inlet 235 and a distributor outlet 236. The distributor inlet 235 is connected to the distribution pipe 33, and the distributor outlet 236 is connected to the inlet of the 3D molding die 32. The feed pipe 21 is a three-way Y-shaped pipe, with one end connected to the screw extruder and the other two ends connected to the distribution pipe 22. The raw material from the screw extruder is evenly distributed in the distribution pipe 22.

[0041] The distributor 23 includes a housing 231 fixed on the frame 1, a stator 232 fixed inside the housing 231, and a rotor 233 located in and adapted to the stator 232. The rotor 233 is provided with two cross-shaped blades 234, which can slide on the rotor 233. The two blades 234 are respectively provided with clearance notches to avoid motion interference. The distributor inlet 235 and the distributor outlet 236 are respectively located on the housing 231 and communicate with the inner cavity of the stator 232.

[0042] When the feeder 23 supplies raw materials to the 3D molding die, the raw materials from the screw extruder push the rotor 233 to move within the stator 232. The rotor 233 is tangential to the stator 232, and the ends of the two blades 234 are always in contact with the inner surface of the rotor 233. The rotor 233, blades 234, and stator 232 form a closed distribution chamber. Along the direction of movement of the rotor 233, the volume of the distribution chamber gradually increases at the feed inlet 235 of the feeder, and raw materials continuously fill the distribution chamber. At the discharge outlet 236 of the feeder, the volume of the distribution chamber gradually decreases, extruding the raw materials in the distribution chamber into the 3D molding die 32. The discharge outlet 236 of the feeder is connected to a discharge connector 230, which is connected to the feed inlet of the 3D molding die 32 via a pipe.

[0043] Furthermore, the position and movement of each rotor 233 are synchronized, and the position and movement of the corresponding blades 234 on each rotor 233 are synchronized. This allows each feeder 23 to operate synchronously, and correspondingly, each 3D molding die 32 can obtain raw materials at the same time. Each 3D molding die 32 can release products onto the conveying mechanism 4 at the same time, ensuring production consistency and improving production efficiency.

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

[0045] A positioning post 239 is provided between each stator 232 and the housing 231 to accurately position each stator 232 in the housing 231.

[0046] like Figures 7-9 As shown, the opening and closing device includes a motor 39, a lifting device, a clamping plate 33, and a guide device. The motor 39 drives the lifting device to lift and lower. The clamping plate 33 is installed on the lifting end of the lifting device. The clamping plate 33 is connected to the 3D molding mold 32. Both ends of the clamping plate 33 are connected to a guide device.

[0047] The lifting device is preferably a gear and rack mechanism, which includes a gear 34 and a rack 35 meshing with the gear 34. The rack 35 is fixed on the guide rail 36. The guide rail 36 is fixedly connected to the clamping plate 33. Guide rollers 37 are rotatably mounted 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 feeder 23 fills the raw material into the 3D molding mold 32 and compacts it in the 3D molding mold 32, the 3D molding mold 32 has a slot connected to the card plate 33. When the card plate 33 moves upward, the 3D molding mold 32 opens and releases the molded product onto the mesh bag conveyor.

[0049] The 3D molding mold 32 is equipped with a water spray nozzle 38 at the product release point. When the product is released, the water spray nozzle 38 sprays water toward the product area to assist in product demolding.

[0050] like Figure 10As shown, the conveying mechanism 4 includes a mesh belt conveyor, which comprises a conveyor support 41 fixed to the frame 1 and a mesh belt mounted on the conveyor support. The conveyor support 41 is equipped 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 positioned opposite each other on both sides of the mesh belt, and the rear pressure plate assemblies 44 are positioned opposite each other on both sides of the mesh belt. The front pressure plate assemblies 43 and the rear pressure plate assemblies 44 press against the mesh belt. When the formed product is released onto the mesh belt, the mesh belt drives the product forward. Due to the downward pressure of the front pressure plate assemblies 43 and the rear pressure plate assemblies 44, both the mesh belt and the product are immersed in the water in the water tray 42 at the position between the front pressure plate assemblies 43 and the rear pressure plate assemblies 44. This water bath helps the product to form and washes away any excess material on the product. A water spray nozzle 38 is located above the water tray 42, and the water sprayed from the water spray nozzle 38 falls into the water tray 42.

[0051] The spray nozzle 38 is connected to the outlet of the water pump 5. A filter box 45 is provided on one side of the water tray 42. The outlet of the filter box 45 is connected to the 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 pumped by the water pump 5 to the spray nozzle 38 to realize the recycling of water.

The scope of protection of the present invention is determined by the claims. Any equivalent modifications based on the technical teachings of the present invention are also within the scope of protection of the present invention.
