[0024] The grinding mechanism includes a first synchronous roller 3, a second synchronous roller 4, and a third synchronous roller 5 which are distributed in a triangular shape, wherein the first synchronous roller 3 and the third synchronous roller 5 are located at the bottom, and the second synchronous roller 4 is located above the first synchronous roller 3 and the third synchronous roller 5, and a grinding belt 6 is wound around the first synchronous roller 3, the second synchronous roller 4, and the third synchronous roller 5.

[0025] Among them, the first synchronous roller 3 is connected to the output end of a rotating motor 31, and the rotating motor 31 is connected to the base through a motor mounting seat 32. The second synchronous roller 4 and the third synchronous roller 5 are rotatably installed on the base through a vertical stand 41 and a support 51 respectively. The lower part of the vertical stand 41 is also rotatably provided with a tensioning roller 7. Under the action of the first synchronous roller 3 and the tensioning roller 7, a certain distance is maintained between the grinding belt 6 and the conveyor belt 21. The first synchronous roller 3 is driven to rotate by the rotating motor 31, and the synchronous rotation of the second synchronous roller 4, the third synchronous roller 5, and the tensioning roller 6 is realized through the transmission effect of the grinding belt 7, thereby realizing the cyclic reciprocating rotation of the grinding belt 7.
