Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice cake processing technology, and in particular to a rice cake grinding device. Background Technology
[0002] The traditional way to make rice cake is to grind soaked rice into rice flour, then add water and stir it into rice paste, then grind the rice paste a second time to form rice embryos, and finally steam the rice embryos into rice cakes.
[0003] A search revealed a prior art rice cake grinding device (publication number: CN103947931B), which includes a device housing. A first roller is transversely inserted inside the device housing. A second roller is obliquely below the first roller. A third roller is obliquely below the second roller. The third roller and the first roller are on the same side of the second roller. The three rollers are driven by a driving device, which is different from the two rollers in a traditional grinding machine.
[0004] In existing technologies, multiple rollers are used to repeatedly grind rice to form rice paste. However, the rice feeding speed affects the grinding effect of the rollers. Existing technologies lack control over the amount of rice fed between the rollers. In actual production, if the amount of rice fed is too much, the rice will not be squeezed by the two rollers. If the amount of rice fed is too little, the rice will not be fully crushed and the efficiency will be low. Therefore, there is room for optimization in the feeding of the rollers.
[0005] Therefore, we propose a rice cake grinding device. Utility Model Content
[0006] The present invention mainly addresses the technical problem of insufficient feed quantity control mentioned above, and provides a rice cake grinding device.
[0007] To achieve the above objectives, this utility model adopts the following technical solution: a rice cake grinding device, comprising:
[0008] The machine body has a cavity in which a first grinding roller, a second grinding roller, and a third grinding roller are rotatably arranged and mutually drive each other. The first grinding roller and the third grinding roller rotate in the opposite direction to the second grinding roller.
[0009] A material guiding structure is installed inside the machine body cavity to convey material to the second grinding roller. The material guiding structure includes a first guide plate and a second guide plate. The first guide plate and the second guide plate are fixedly connected and jointly form a V-shaped material trough facing the second grinding roller.
[0010] An adjustment component is provided on the second guide plate for adjusting the feeding speed. The adjustment component includes a gate and a feed inlet. The feed inlet is provided through the second guide plate. The gate is slidably disposed on one side of the second guide plate. The gate can partially block the feed inlet to adjust the feeding amount.
[0011] In a preferred embodiment of this utility model, the first guide plate and the second guide plate are rectangular plates of equal length, forming a V-shaped folded plate, and the ends of the first guide plate and the second guide plate are fixedly connected to the inner wall of the machine body.
[0012] In a preferred embodiment of this utility model, a bracket is fixedly installed on one side of the first guide plate, and a spray pipe is fixedly installed on the bracket.
[0013] In a preferred embodiment of this utility model, the adjusting component further includes thrust holes. A plurality of linearly distributed thrust holes are provided on one side of the second guide plate. Bolts are threaded into the thrust holes and penetrate the gate plate.
[0014] In a preferred embodiment of the present invention, the adjustment assembly further includes adjustment channels and protrusions. Two adjustment channels are also provided on one side of the second guide plate, and two protrusions are fixedly installed on one side of the gate plate, with the protrusions slidably disposed in the corresponding adjustment channels.

The rice can be milled twice by the first roller 11, the second roller 12 and the third roller 13 to form rice paste. This is a known prior art and will not be described in detail here.
[0029] like Figure 2 and Figure 3 As shown, a material guiding structure is installed inside the cavity of the machine body 10 to convey material to the second grinding roller 12. The material guiding structure includes a first guide plate 14 and a second guide plate 15, which are fixedly connected and together form a V-shaped material trough facing the second grinding roller 12. The first guide plate 14 and the second guide plate 15 are rectangular plates of equal length, forming a V-shaped fold. The ends of the first guide plate 14 and the second guide plate 15 are fixedly connected to the inner wall of the machine body 10. The material guiding structure also includes... An extension plate 16 is fixedly connected to a second guide plate 15. The end of the extension plate 16 abuts against the circumferential surface of the first roller 11, and the end of the second guide plate 15 abuts against the circumferential surface of the second roller 12. The material guiding structure also includes a scraper 18, which is fixedly connected to the inner wall of the machine body 10. The scraper 18 abuts against the circumferential surface of the third roller 13 and extends obliquely to the tangent position of the second roller 12 and the third roller 13. A bracket 17 is fixedly installed on one side of the first guide plate 14, and a spray pipe is fixedly installed on the bracket 17.
[0030] In this design, a V-shaped funnel is formed by the first guide plate 14 and the second guide plate 15 to feed rice and water into the tangent of the first milling roller 11 and the second milling roller 12. The second guide plate 15 can scrape and clean the rotating second milling roller 12, the extension plate 16 can scrape and clean the first milling roller 11, and the scraper 18 is used to scrape, clean, and guide the third milling roller 13. The extension plate 16 is an arc-shaped plate. The irregular plate formed by the first guide plate 14, the second guide plate 15, and the extension plate 16 can respectively contact the first milling roller 11 and the second milling roller 12. The overall structure is stable. While ensuring the guiding effect, it is not easy to be fatigued and broken. It has a higher integration and is convenient for disassembly and maintenance. The spray pipe is connected to a water source to add water to the rice.
[0031] like Figure 3 , Figure 4 and Figure 5 As shown, the adjustment component is set on the second guide plate 15 to adjust the feeding speed. The adjustment component includes a gate plate 20 and a feed inlet 21. The feed inlet 21 is opened through the second guide plate 15. The gate plate 20 is slidably set on one side of the second guide plate 15. The gate plate 20 can partially block the feed inlet 21 to adjust the feeding amount.

Bolts are threaded to the thrust holes 22 and the bolts pass through the gate plate 20. The adjustment component also includes adjustment channels 23 and protrusions 24. Two adjustment channels 23 are also opened on one side of the second guide plate 15. Two protrusions 24 are fixedly installed on one side of the gate plate 20. The protrusions 24 are slidably set in the corresponding adjustment channels 23.
[0032] Considering that the feed rate needs to be adjusted, by pushing the gate 20 to move, the protrusion 24 slides in the adjustment channel 23, and the bolt is rotated. The bolt is fastened to the corresponding thrust hole 22 to fix the position of the gate 20. The gate 20 partially blocks the feed port 21 to adjust the opening of the feed port 21, thereby controlling the feed rate. It has flexible adjustability and the adjustment method is simple, quick and easy to operate.
[0033] The working principle of this utility model is as follows: A V-shaped funnel is formed by the first guide plate 14 and the second guide plate 15 to feed rice and water into the tangent of the first milling roller 11 and the second milling roller 12.

The gate plate 20 partially blocks the feed inlet 21 to adjust the opening of the feed inlet 21 and realize the control of the feed amount.
[0034] The output shaft of the drive motor is fixedly connected to the first grinding roller 11. The first grinding roller 11 drives the second grinding roller 12 to rotate, and the second grinding roller 12 drives the third grinding roller 13 to rotate. The first grinding roller 11 is located diagonally above the second grinding roller 12, and the third grinding roller 13 is located diagonally below the second grinding roller 12.
