[0026] Further, as Figure 2-4 shown, a rotating shaft 41 is rotatably connected to the inside of the discharge pipe 23; the rotating shaft 41 and the grinding shaft are connected by a synchronous belt; a scraping rod 42 is fixedly connected to the rotating shaft 41; the scraping rod 42 is attached to the inner side wall of the filter mesh cover 24; during use, the grinding shaft drives the rotating shaft 41 to rotate through synchronous belt deceleration, and the rotation of the rotating shaft 41 will drive the scraping rod 42 to rotate inside the filter mesh cover 24 to dredge the situation where a small amount of large particle solids block the filter mesh cover 24, thereby reducing the situation where the filter mesh cover 24 is blocked and facilitating filtration.

[0030] Working principle: During use, solid coating raw materials are poured from the material guiding groove 17 and then enter between the two crushing rollers 16 for crushing. The crushing rollers 16 are driven to rotate by a reduction motor 15.

The ground coating will be aggregated in the collecting hopper 21 and then discharged from the discharge pipe 23. The bottom of the discharge pipe 23 is provided with a fixed seat 22 for cooperating with the limit block to fix the filter net. The filter net is used for filtering to reduce the situation of large particles in the coating. The staff can remove the fixed seat 22 to remove the filter mesh cover 24 and then replace the filter mesh cover 24 with different mesh numbers according to needs. The grinding shaft drives the rotating shaft 41 to rotate through synchronous belt reduction. The rotation of the rotating shaft 41 will drive the scraping rod 42 to rotate inside the filter mesh cover 24 to dredge the situation where a small amount of large particle solids block the filter mesh cover 24, thus reducing the situation where the filter mesh cover 24 is blocked and facilitating filtration. The arc-shaped scraping rod 42 will move the large particle solid coating raw materials upward along the inner wall of the filter mesh cover 24 to push the solid coating raw materials out of the filter mesh cover 24. Then the accumulated solid coating raw materials fall into the interior of the collecting box 52 from the discharge chute, reducing the situation where the solid coating raw materials accumulate in the filter mesh cover 24. The material guiding cover 6 is used to guide the crushed solid coating raw materials to fall into the gap between the grinding seat 18 and the grinding wheel 19, facilitating grinding. The support rod is used to support and fix the material guiding cover 6.
