[0001] This utility model relates to the field of grinding, and more specifically, it relates to a small bean product grinding device. Background Technology

[0002] Soy products are very popular foods, and there are many kinds of soy products. Many soy product production processes require grinding soybeans, which requires the use of soy product grinding equipment. Most existing soy product grinding equipment lacks automatic screening and re-grinding structures, which results in uneven particle size in the ground soy powder or soy paste. Workers need to manually or with the help of other screening devices to filter and screen the particles in the soy powder or soy paste, and then pour the coarser particles back into the grinding equipment for re-grinding, which is quite troublesome.

[0003] Based on the above, the purpose of this utility model is to provide a small-scale soybean product grinding device to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a small-scale soybean product grinding device. This invention involves setting up a circulating sleeve around the grinder, on which a filter plate and multiple push plates are installed to push the raw materials along its inner cavity. The powder particles after grinding by the grinder enter the circulating sleeve. The finer powder particles are discharged through the filter plate, while the coarser powder particles are pushed by the push plates to the discharge trough at the top of the circulating sleeve. The powder particles will pass through the discharge trough and the conveying channel and return to the feed pipe, and then be ground again.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a small soybean product grinding device, including a frame, a grinder fixedly connected to the frame, a feed pipe, a grinding disc, and a discharge pipe provided on the grinder, the grinding disc including an upper grinding disc and a lower grinding disc, the upper grinding disc being fixedly connected to the grinder, the lower grinding disc being rotatably connected to the grinder, a first driving mechanism for driving the lower grinding disc to rotate provided on the frame, a circulating sleeve fixedly connected to the frame, the discharge pipe communicating with the circulating sleeve, the circulating sleeve being annular, a discharge port and a discharge outlet respectively provided on the upper and lower sides of the circulating sleeve, a conveying channel provided between the discharge port and the feed pipe, a filter plate provided at the discharge outlet, the filter plate being arc-shaped, mounting rings slidably connected to both sides of the inner wall of the circulating sleeve, a plurality of push plates fixedly connected between the mounting rings on both sides, and a second driving mechanism for driving the plurality of push plates to move along the trajectory of the circulating sleeve provided on the frame.

[0006] By adopting the above technical solution, when grinding soybean products is required, the lower grinding disc is driven to rotate by the first drive mechanism, and the soybean raw material is poured into the feed pipe. The raw material will slide into the space between the upper and lower grinding discs through the feed pipe. The rotating lower grinding disc will work with the upper grinding disc to grind the raw material. The ground powder particles enter the circulation sleeve through the discharge pipe.

[0010] The present invention is further configured such that both the mounting block and the positioning groove are polygonal structures.

[0011] The present invention is further configured such that the push plate is provided with a plurality of filter holes.

[0012] In summary, this utility model has the following beneficial effects: This invention features a circulating sleeve surrounding the grinder. The circulating sleeve is equipped with a filter plate and multiple push plates that move the raw material along its inner cavity. The powder particles after grinding enter the circulating sleeve. The finer powder particles are discharged through the filter plate, while the coarser powder particles are pushed by the push plates to the discharge trough at the top of the circulating sleeve.

[0019] A small soybean product grinding device, such as Figures 1 to 4 As shown, the machine includes a frame 1, on which a grinder 2 is fixedly connected. The grinder 2 is equipped with a feed pipe 3, a grinding disc, and a discharge pipe 4. The grinding disc is installed inside the grinder cavity and includes an upper grinding disc 5 and a lower grinding disc 6. The upper and lower grinding discs can be grinding wheels used for grinding beans. Grinding discs are a mature existing technology, and their specific structure and grinding principle will not be elaborated here. The upper grinding disc 5 is detachably connected to the grinder 2 by bolts, and the lower grinding disc 6 is rotatably connected to the grinder 2. A drive mechanism for rotating the lower grinding disc 6 is provided on the frame 1. A circulation sleeve 7 is fixedly connected to the frame 1, and the discharge pipe 4 is connected to the circulation sleeve 7. The circulation sleeve 7 is annular, and openings are provided on its upper and lower sides. There is a discharge port 8 and a discharge port 9. The discharge port 8 and the feed pipe 3 are fixedly connected by a conveying channel 10 to allow them to communicate with each other. A filter plate 11 is installed at the discharge port 9. The filter plate can be detachably connected to the circulating sleeve by means of bolts, nuts and other tools. The filter plate 11 is arc-shaped and the arc matches the arc of the outer wall of the annular sleeve. The inner wall of the circulating sleeve 7 is slidably connected to both sides of the inner wall by mounting rings 12. Several push plates 13 are fixedly connected between the two mounting rings 12. The frame 1 is equipped with a drive mechanism 2 that drives the multiple push plates 13 to move along the trajectory of the circulating sleeve 7. The circulating sleeve and the grinder can both be designed as separate structures and can be detachably connected by means of bolts and other tools, which facilitates the installation and maintenance of accessories such as grinding discs and push plates.

[0020] Furthermore, the drive mechanism includes a motor 14 fixedly connected to the frame 1, a drive shaft 15 rotatably connected to the frame 1, a belt pulley transmission assembly 16 between the output shaft of the motor 14 and the drive shaft 15, the belt pulley transmission assembly includes two pulleys fixedly connected to the output shaft of the motor and the drive shaft respectively, a transmission belt is sleeved between the two pulleys, and the lower grinding disc 6 is fixedly connected to the drive shaft 15.

[0021] Furthermore, the second drive mechanism includes a drive gear 17 fixedly connected to the drive shaft 15, a rotating shaft 18 rotatably connected to the frame 1, a driven gear 19 meshing with the drive gear 17 fixedly connected to one end of the rotating shaft 18, a cooperating gear 20 fixedly connected to the other end of the rotating shaft 18, and an internal gear ring 21 fixedly connected to one side of the mounting ring 12 extending outside the circulation sleeve 7. The cooperating gear 20 meshes with the internal gear ring 21.

[0022] Furthermore, a mounting block 22 is fixedly connected to the drive shaft 15. The mounting block 22 is provided with a lead screw 23 fixedly connected to one end. The other end of the lead screw 23 extends into the feed pipe 3. The lower grinding disc 6 is provided with a positioning groove for the mounting block 22 to be inserted and a clearance groove for the lead screw 23 to pass through. A push screw 24 is sleeved on the lead screw 23. The lead screw passes through the center of the push screw. Several fastening nuts are threaded on the lead screw. The push screw and the lower grinding disc are clamped by the mounting block and the fastening nuts. The thread tightness of the fastening nuts can be improved by using wedge-shaped washers. A push groove 25 is provided on the upper grinding disc 5 for the push screw 24 and the bean raw material to pass through.

[0023] Furthermore, both the mounting block 22 and the positioning slot are polygonal structures.

[0024] Furthermore, the push plate 13 has several filter holes.

[0025] Working principle: When grinding soybean products is required, the motor 14 is started. The output shaft of the motor 14 drives the drive shaft 15 to rotate through the belt pulley transmission assembly 16. The drive shaft 15 drives the lower grinding disc 6 to rotate through the mounting block 22 and the positioning groove. The drive shaft 15 also drives the push screw to rotate through the lead screw 23 and the fastening nut. Then, the soybean raw materials are poured into the feed pipe 3. As the raw materials move along the trajectory of the feed pipe 3, the push screw will drive the raw materials to move along its spiral trajectory through the push groove 25 and into the space between the upper grinding disc 5 and the lower grinding disc 6. The rotating lower grinding disc 6 will cooperate with the upper grinding disc 5 to grind the raw materials. The ground powder particles enter the circulation sleeve through the discharge pipe 4.

[0026] During the appeal process, the drive shaft 15 will also drive the driven gear 19 to rotate via the drive gear 17. The driven gear 19 will drive the cooperating gear 20 to rotate via the rotating shaft 18. The cooperating gear 20 will then drive the mounting ring 12 to rotate via the internal gear ring 21. The mounting ring will then drive multiple push plates 13 to circulate along the inner cavity trajectory of the circulating sleeve 7. During this process, the finer powder in the circulating sleeve will pass through the filter plate 11 and be discharged. A container can be placed under the filter plate for collection, or a sealed collection box can be welded. The collection box is fixedly connected to the discharge pipe and valve. The powder raw material is collected through the collection box. When it needs to be removed, the valve is opened to allow the powder to be discharged through the discharge pipe. The coarser particles that cannot pass through the filter plate will move along the inner cavity trajectory of the circulating sleeve under the push of the push plate 13 until the raw material particles move to the discharge trough at the top of the circulating sleeve. The raw material particles will then pass through the discharge trough and the conveying channel 10 back to the feed pipe 3, and then be ground again. With this setting, the grinding device can automatically complete the screening and re-grinding, making the ground particles more uniform, thereby improving the quality of the ground product.

[0027] During the appeal process, since the diameter of the cooperating gear 20 is much smaller than the diameter of the internal gear ring 21, the moving speed of the push plate 13 is low. As the push plate 13 pushes the powder material to move slowly, the powder material can have a certain amount of time to dissipate heat, thus avoiding excessively high temperatures accumulating in the powder particles during the re-grinding process, which would affect the quality.

[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
