[0002] Powder coatings are solid powder synthetic resin coatings composed of solid resins, pigments, fillers, and additives. Their processing steps are usually three steps. The first step is to premix all the coarse-grained raw materials with relevant additives. The second step is to melt the premixed raw materials through an extruder, homogenize the components in the coating during this process, and press them into sheets. The third step is to cut the formed sheets into pieces, grind the pieces with a powder mill, screen the ground powder, and package it to form a product.

[0003] After retrieval, a Chinese patent with the application number 201920116093.2 discloses a powder coating mill. By respectively passing the upper connection hole and the lower connection hole through the side walls of the upper connection seat and the lower connection seat, after the upper shell and the grinding body are covered, the threaded rod hinged at the position of the lower connection hole rotates to the upper end and passes through the upper connection hole, and then the pressing disc rotates and presses down, and the upper shell and the grinding body can be pressed and sealed; similarly, when it needs to be opened, the pressing disc is screwed out, and then the threaded rod is flipped down to open the upper shell, which can facilitate the opening or closing of the powder mill.

[0004] Regarding the above technology, the inventor believes that when the device is grinding powder, the powder coating will adhere to the inner wall of the powder mill shell, resulting in uneven grinding of the powder coating.

[0012] Preferably, a connecting seat is arranged at the top end of the cover plate, and a discharge port is arranged on the side wall.

[0013] The technical effects and advantages of the present utility model:

[0014] Compared with the prior art, the present utility model seals the outer shell of the grinder through the cover plate, and uses the sealing ring arranged on the surface of the cover plate to increase the sealing performance of the outer shell of the grinder. Then, the driving device drives the grinding disc to work to grind the coating raw materials. At the same time, the driving device drives the outer ring to rotate, thereby driving the scraping blade to rotate, and the scraping blade scrapes the coating raw materials on the inner wall of the outer shell of the grinder, so that the grinding disc can grind, making the powder coating more uniform.
