[0023] The inner wall of the shell 1 is provided with a mounting groove 2, and a driving mechanism is provided in the mounting groove 2. The driving mechanism includes a servo motor 3 fixedly mounted on the top of the mounting groove 2, and a threaded rod 4 is fixedly connected to the end of the output shaft of the servo motor 3. The side wall of the threaded rod 4 is threadedly connected to a threaded block 5. The threaded block 5 is slidably connected to the mounting groove 2. Through the setting of the driving mechanism, the threaded rod 4 can be driven by the servo motor 3 to rotate, thereby driving the threaded block 5 to slide up and down in the mounting groove 2, so as to adjust the gap between the polyester adhesive layer 8 and the extrusion plate 9, so as to carry out rice milling processing of different specifications;

[0024] A rice milling mechanism is provided on the side wall of the driving mechanism, and a mounting frame 11 is fixedly installed on the inner side wall of the shell 1. The rice milling mechanism includes a driving roller body 6 fixedly installed on the side wall of the threaded block 5, and a shock-absorbing layer 7 is fixedly installed on the outer wall of the driving roller body 6. A polyester adhesive layer 8 is fixedly installed on the outer wall of the shock-absorbing layer 7. Through the setting of the rice milling mechanism, the polyester adhesive layer 8 can be driven to rotate by the drive of the driving roller body 6, and the rice milling process is carried out in conjunction with the extrusion of the extrusion plate 9.

[0025] The functional principle of this utility model can be explained through the following operation modes:

[0026] In the present invention, when the staff uses the present invention, the staff drives the servo motor 3 to operate and drive the threaded rod 4 to rotate. The rotation of the threaded rod 4 will drive the threaded block 5 slidably connected to the mounting groove 2 to slide up and down in the mounting groove 2, thereby driving the polyester adhesive layer 8 to slide up and down, thereby adjusting the gap between the polyester adhesive layer 8 and the extrusion plate 9. Then the staff drives the driving roller 6 to rotate, and the rotation of the polyester adhesive layer 8 and the extrusion of the extrusion plate 9 can be used to perform rice milling of different specifications. The practical effect is wide. After a long period of rice milling, many impurities and debris will remain on the surface of the polyester adhesive layer 8. , the staff can reversely drive the servo motor 3 to move the polyester adhesive layer 8 upward through the above operation. The polyester adhesive layer 8 squeezes the cleaning cloth 15 and the slider 10, so that the slider 10 slides into the slide groove 13. At this time, the slider 10 is subjected to the elastic force of multiple first springs 14, so that the cleaning cloth 15 and the surface of the polyester adhesive layer 8 are better fitted. Subsequently, the staff drives the driving roller body 6 to rotate, and the high-speed rotation of the driving roller body 6 can drive the surface of the polyester adhesive layer 8 and the cleaning cloth 15 to rub and clean. The debris wiped off will fall into the installation frame 11 at the bottom of the cleaning cloth 15 due to gravity, which is convenient for the staff to recycle and reuse.
