The grinding and feeding mechanism is located at the top of the coating box 1 and is used to provide powder for the coating work and to crush and convey the agglomerated powder. The processing box 416 is located on the top of the coating box 1. Inside the processing box 416 and at the bottom, there is a guide platform 404. There are two guide platforms 404 symmetrically arranged relative to the processing box 416, which are used to guide the grinding coating powder and the powder shaken off into the coating box 1. The scraper 403 is located inside the processing box 416 and at the top. There are two scrapers 403 symmetrically arranged relative to the processing box 416. The bottom of the scraper 403 points to the outside of the grinding feeding mechanism and is used to scrape off the powder attached to the surface of the grinding mechanism after grinding and make it fall onto the guide table 404.

[0016] The grinding assembly includes a connecting frame 401, a motor 402, a rotating shaft 405, and a spur gear 406. A feed box 417 is located on the top of the processing box 416, and a cover is provided on the top of the feed box 417. The cover can be rotated to open or close the top of the feed box 417. The feed box 417 is used to store coating powder.

At one end, a spur gear 406 is located at one end of a rotating shaft 405 near a motor 402. A second spur gear 407 meshes with the side of the first spur gear 406. A grinding roller 409 is located on the outer side of the rotating shaft 405. The motor 402 drives the rotating shaft 405 to rotate, which in turn drives the first spur gear 406 to rotate. The first spur gear 406 drives the second spur gear 407 to rotate in the opposite direction. Therefore, the first spur gear 406 and the second spur gear 407 drive the grinding roller 409 to rotate in opposite directions, thereby grinding the solid material.

[0017] The striking assembly includes a toggle element 408, a rotating plate 410, a spring 411, and a connecting shaft 412.

The rotating shaft 405 drives the actuating member 408 to rotate clockwise. When the end of the actuating member 408 contacts the rotating plate 410, it drives the rotating plate 410 to rotate upward. At this time, the spring 411 is stretched, and the actuating member 408 continues to rotate and disengages from the rotating plate 410. The rotating plate 410 rebounds quickly under the action of the spring 411, thereby driving the striking block 414 to strike the grinding roller 409 through the striking plate 413.

[0020] In summary, when using this utility model, the three-jaw chuck 303 is opened to clamp one end of the motor rotor inside, and the two ends abut against the side of the support plate 304 to fix the position of the rotor. The top cover is opened, and then the coating powder is poured into the feed box 417. The powder enters the processing box 416 through the feed box 417 and falls between the two grinding rollers 409. The motor 402 is started, which drives the shaft 405 to rotate. The shaft 405 drives the gear 406 to rotate, and the gear 406 drives the gear 407 to rotate in the opposite direction. Therefore, the gears 406 and 407 drive the grinding rollers 409 to rotate in opposite directions, thus grinding the solid... The material is being ground, and at the same time, the rotating shaft 405 drives the actuating element 408 to rotate clockwise. When the end of the actuating element 408 contacts the rotating plate 410, it drives the rotating plate 410 to rotate upward. At this time, the spring 411 is stretched, and the actuating element 408 continues to rotate and disengages from the rotating plate 410. The rotating plate 410 rebounds quickly under the action of the spring 411, thereby driving the striking block 414 to strike the grinding roller 409 through the striking plate 413. This not only knocks the powder off the grinding roller 409, but also breaks up the powder that is stuck together. The ground powder slides into the spray gun 419 through the guide table 404. The spray gun 419 moves back and forth under the drive of the power plate 418, thereby coating the rotating rotor back and forth.
