[0004] Although this can improve the extrusion efficiency and uniform extrusion, but: this die does not uniformly guide and divide the rice flour raw materials, cannot guarantee that the basic amount is uniform and equal, lateral extrusion can cause knotting and interference between rice flour, cannot guarantee the independent extrusion of rice flour, although the installation is simple, but the rice flour raw materials are not transitioned and divided, cannot guarantee that the extrusion amount of rice flour raw materials is stable and the same, is prone to extrusion interruption, in addition, cannot extrude different specifications of rice flour, cannot realize flexible disassembly and assembly, needs to replace new dies, and improves the processing cost. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides a flat extrusion die for rice flour to solve the problems raised in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flat extrusion die for rice noodles, comprising a main cavity, a side sealing plate welded to one side of the main cavity, a feeding hole provided at the top of the main cavity, a feeding adapter welded to the feeding hole, a sealing groove provided at the bottom of the main cavity, an extrusion template interference fit within the sealing groove, a row of feeding holes provided on the extrusion template, a sealing mechanism provided below the extrusion template, the sealing mechanism being movably connected to the main cavity, a row of extrusion holes provided on the extrusion template, a flow guiding component provided inside the main cavity, the flow guiding component being located above the extrusion template, the flow guiding component uniformly guiding the rice noodle raw material, and a flow splitting component provided above the flow guiding component to distribute the rice noodle raw material. The rice noodle raw materials are evenly distributed. The diversion assembly includes, from top to bottom, a uniform distribution guide plate, an upper diversion plate, a lower diversion plate, a first diversion plate, and a second diversion plate.

The second diversion plates are welded into the main cavity. The two ends of the upper diversion plate are located at the center of the second diversion plate. A first diversion plate is also arranged on one side of the second diversion plate and is welded to the side wall of the main cavity. The gap between the first diversion plate and the second diversion plate is the same as the gap between the second diversion plate and the lower diversion plate.

[0007] As an optional embodiment of the present invention, the sealing mechanism includes a sealing plate, one end of which is welded with a cylindrical hinge and connected to one side of the main cavity. The sealing plate is provided with a guide port for the forming and feeding of rice noodles. One side of the sealing plate is provided with a folded edge, which is threadedly fixed to one side of the main cavity by a high-strength bolt.

[0008] As an optional embodiment of the present invention, the extrusion hole is a countersunk hole with a large diameter of 4 mm and a small diameter of 2 mm.

[0012] This invention provides a flat extrusion die for rice noodles, which has the following advantages:

[0013] The rice noodle raw material is evenly distributed to both sides by a uniform guide plate. After flowing to the upper distribution plate, it is evenly distributed to the second distribution plate, and then evenly distributed to both sides by the second distribution plate. The material is evenly fed through the gaps in the first distribution plate and the gaps at both ends of the lower distribution plate, thus ensuring equal extrusion volume. Then, it is evenly extruded through the guide holes on the upper and lower guide plates, and finally, it is quickly extruded and shaped through the extrusion template, ensuring that the extrusion volume is uniform. A quick-disassembly sealing plate is set up so that when rice noodles of different shapes or diameters need to be formed, the sealing plate can be quickly disassembled, the extrusion template can be removed, and a new extrusion template can be replaced. No whole-house manufacturing is required, which greatly reduces costs and makes disassembly and assembly convenient. Attached Figure Description

[0022] Please see Figures 1 to 4 This invention provides a technical solution: a flat extrusion die for rice noodles, comprising a main cavity 1, a side sealing plate 3 welded to one side of the main cavity 1, a feeding hole at the top of the main cavity 1, a feeding adapter 2 welded to the feeding hole to ensure overall sealing, a sealing groove at the bottom of the main cavity 1, an extrusion template 5 interference fit within the sealing groove, a row of feeding holes on the extrusion template 5, and a sealing mechanism below the extrusion template, which is movably connected to the main cavity 1 to facilitate replacement of extrusion templates 5 of different specifications. The sealing mechanism includes a sealing plate 4, a cylindrical hinge 6 welded to one end of the sealing plate 4, which is connected to one side of the main cavity 1 via the cylindrical hinge 6 to seal the pressure plate. The plate 4 is equipped with a guide port 401 for the forming and feeding of rice noodles. The sealing pressure plate 4 has a folded edge on one side, which is fixed to the side of the main cavity 1 by high-strength bolts for more flexible use. The extrusion template 5 is equipped with a row of extrusion holes 501. The extrusion holes 501 are countersunk holes with a large diameter of 4mm and a small diameter of 2mm, so that the extrusion diameter is uniform. In addition, the extrusion holes 501 on the extrusion template 5 can be changed in size and shape according to actual needs to achieve rice noodles of different sizes and shapes. The main cavity 1 is equipped with a flow guiding component located above the extrusion template 5. The flow guiding component can guide the rice noodle raw materials evenly.

[0023] The flow guiding assembly includes a lower flow guiding plate 7, which is welded inside the main cavity 1. The lower flow guiding plate 7 is provided with multiple flow guiding holes 701, which are arranged in an array and are oblong. An upper flow guiding plate 8 is provided above the lower flow guiding plate 7, and the upper flow guiding plate 8 is provided with the same flow guiding holes 701 as the lower flow guiding plate 7. The gap width between the flow guiding holes 701 is 0.7mm, so as to evenly discharge the rice noodle raw materials. A flow dividing assembly is also provided above the flow guiding assembly to evenly distribute the rice noodle raw materials.

[0024] The diversion assembly, from top to bottom, includes a uniform diversion guide plate 13, an upper diversion plate 12, a lower diversion plate 11, a first diversion plate 9, and a second diversion plate 10. The uniform diversion guide plate 13 has an obtuse triangular cross-section with an obtuse angle of 150 degrees, thus ensuring that the rice noodle raw material is evenly distributed to both sides. The upper diversion plate 12 is located directly below the uniform diversion guide plate 13, and its length is twice that of the uniform diversion guide plate 13, ensuring that the distance from the point where the rice noodle raw material falls to both ends of the upper diversion plate 12 is equal, resulting in uniform diversion. A lower flow divider 11 is provided directly below the plate 12, and symmetrical second flow dividers 10 are provided on both sides of the lower flow divider 11. The second flow dividers 10 are welded inside the main cavity 1. The two ends of the upper flow divider 12 are located at the center of the second flow dividers 10. A first flow divider 9 is also provided on one side of the second flow divider 10. The first flow divider 9 is welded to the side wall of the main cavity 1. The gap between the first flow divider 9 and the second flow divider 10 is the same as the gap between the second flow divider 10 and the lower flow divider 11, so as to ensure the uniform balance of the extrusion volume.

[0025] The specific usage and function of this embodiment: After fermentation and mixing, the rice flour raw materials enter the screw extruder. The screw extruder forces the rice flour raw materials into the main cavity 1. After entering the main cavity 1, the rice flour raw materials are first evenly distributed to both sides by the equalizing guide plate 13, flow to the upper distribution plate 12, and then evenly distributed to the second distribution plate 10. The second distribution plate 10 evenly distributes the raw materials to both sides. The raw materials are evenly fed through the gaps of the first distribution plate 9 and the gaps at both ends of the lower distribution plate 11, thereby ensuring that the extrusion amount is equal. Then, the raw materials are evenly extruded through the guide holes 701 on the upper guide plate 8 and the lower guide plate 7. Finally, the raw materials are quickly extruded and shaped through the extrusion template 5, ensuring that the extrusion amount is uniform and equal. When it is necessary to form rice flour of different shapes or different diameters, the sealing pressure plate 4 can be quickly disassembled, the extrusion template 5 can be removed, and a new extrusion template 5 can be replaced. No overall manufacturing is required, which greatly reduces costs and makes disassembly and assembly convenient.
