Description

Technical Field

[0001] This utility model relates to the field of rice noodle production technology, and in particular to a grinding device for rice noodle production. Background Technology

[0002] Rice noodles are a specialty snack in southern China. People in Jiangxi usually just call them "fen". Rice noodles are made from rice and are processed through soaking, steaming, and pressing to make strips or strands. They are not, as the name suggests, a powdery material made from rice.

[0003] In the production of rice noodles, soaked rice needs to be ground into a paste. In the existing technology, most rice noodle grinding devices generally crush and filter the rice before grinding. Since the ground paste usually passes through the filter screen by its own gravity and is continuously filtered, incompletely crushed rice accumulates on the filter screen, causing the filter screen to become clogged and the paste output efficiency to be low, which is not practical enough. Therefore, it is necessary to redesign a rice noodle grinding device to address the above problems. Utility Model Content

A first motor connected to the rotating shaft of one of the crushing rollers is fixedly installed on the outer wall of the feed hopper. The outer walls of the two crushing roller rotating shafts are connected by a rotating mechanism. Connecting plates are fixedly installed on both sides of the inner wall of the grinding box.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5A grinding device for rice noodle production includes a grinding box 1. A feed hopper 2 is fixedly installed on the upper surface of the grinding box 1 through an installation opening. Two crushing rollers 3 are fixedly installed inside the feed hopper 2. A first motor 4 connected to the rotating shaft of one of the crushing rollers 3 is fixedly installed on the outer wall of the feed hopper 2. The outer walls of the rotating shafts of the two crushing rollers 3 are connected by a rotating mechanism. The rotating mechanism includes gears 5 fixedly installed on the outer walls of the rotating shafts of the two crushing rollers 3. The two gears 5 mesh with each other. Connecting plates 6 are fixedly installed on both sides of the inner wall of the grinding box 1. Filter plates 8 are fixedly installed on the upper surfaces of the two connecting plates 6 through an elastic mechanism. A damping spring telescopic rod 7 is fixedly installed on the upper surface of the connecting plates 6 by the elastic mechanism. The damping spring telescopic rod 7 is a telescopic device that combines damping technology and spring structure. It is mainly used to reduce vibration and impact and provide a smooth telescopic effect. When the spring vibrates, it consumes energy due to friction and external resistance, thereby reducing the vibration amplitude and mitigating the impact on the system and the environment.

[0023] The telescopic end of the damping spring telescopic rod 7 is fixedly connected to the bottom wall of the filter plate 8. An extrusion block 9 is fixedly installed on the bottom wall of the filter plate 8. An extrusion groove is opened on the bottom wall of the extrusion block 9. An extrusion shaft 10 is rotatably installed inside the grinding box 1. A second motor 11 connected to the extrusion shaft 10 is fixedly installed on the outer wall of the grinding box 1. A cam 12 is fixedly installed on the outer wall of the extrusion shaft 10. A support plate 13 is fixedly installed on the outer wall of the grinding box 1. A push plate 15 is fixedly installed on the inner wall of the support plate 13 through a telescopic mechanism. The telescopic mechanism includes an electric push rod 14 fixedly installed on the inner wall of the support plate 13. The telescopic end of the electric push rod 14 is fixedly connected to the outer wall of the push plate 15. Push openings are opened on both sides of the outer wall of the grinding box 1. A guide plate 16 that cooperates with one of the push openings is fixedly installed on the outer wall of the grinding box 1. A transmission rod 17 is rotatably installed inside the grinding box 1. The extrusion shaft 10 is connected to the outer wall of the transmission rod 17 through a transmission mechanism.

[0024] The transmission mechanism includes pulleys 18 fixedly installed on the outer wall of the extrusion shaft 10 and the transmission rod 17. The two pulleys 18 are connected by a belt for transmission. A rotating shaft is rotatably installed on the inner wall of the grinding box 1 through a partition 20. The rotating shaft is connected to the outer wall of the transmission rod 17 through a meshing mechanism. The meshing mechanism includes bevel gears 19 fixedly installed on the outer wall of the transmission rod 17 and the transmission shaft. The two bevel gears 19 mesh with each other. A grinding block 21 is fixedly installed at the end of the rotating shaft. A feeding box 22 is fixedly installed on the inner wall of the grinding box 1. A grinding plate 23 that cooperates with the grinding block 21 is fixedly installed on the inner wall of the grinding box 1. A discharge pipe 24 communicating with the outside is opened on the inner wall of the grinding box 1.

[0025] In use, the soaked rice is fed into the feed hopper 2. Then, the first motor 4 drives one of the crushing rollers 3 to rotate. This crushing roller 3, through two meshing gears 5, drives the other crushing roller 3 to rotate. The two crushing rollers 3 rotate in opposite directions to crush the rice. After crushing, the rice falls onto the filter plate 8. Simultaneously, the second motor 11 drives the extrusion shaft 10 to rotate. The extrusion shaft 10 then drives the cam 12 to rotate and contact the inner wall of the extrusion groove. This causes the extrusion block 9 to be subjected to force, moving the filter plate 8 and pulling the damping spring. When the cam 12 is not in contact with the inner wall of the extrusion groove, the filter plate 8 can move and reset under the elastic action of the damping spring telescopic rod 7. When the cam 12 rotates continuously and intermittently contacts the inner wall of the extrusion groove, the filter plate 8 can be shaken up and down under the extension and retraction action of the damping spring telescopic rod 7. This allows the rice on the surface of the filter plate 8 to fall off, avoiding excessive rice residue on its surface that could cause blockage. The rice that is not shaken off can be pushed off the filter plate 8 by the extension and retraction action of the electric push rod 14, which drives the push plate 15, and then collected by the guide plate 16.

[0026] The shaken rice falls into the feeding box 22, through which the crushed rice is fed into the grinding assembly. Then, under the rotation of the extrusion shaft 10, the two pulleys 18 connected by the belt drive the transmission rod 17 to rotate. When the transmission rod 17 rotates, it drives one of the bevel gears 19 to rotate. When one bevel gear 19 rotates, it drives the other bevel gear 19 to rotate. At this time, the rotation of the two meshing bevel gears 19 drives the grinding block 21 to rotate. When the grinding block 21 rotates, it rubs against the grinding plate 23, thereby grinding the rice between them. After the rice is ground, it can be discharged through the discharge pipe 24.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
