The convex block 25 extends into the inside of the movable frame 26. Above the movable frame 26, a lifting frame 27 is fixedly installed. At the top of the lifting frame 27, a sealing plate 28 is fixedly installed.

[0025] When the staff uses it, the staff first place the parts to be sprayed above the conveyor belt 4, and then start the first motor 6 to drive the rotation of the rotating roller 3. When the rotating roller 3 rotates, it will drive the conveyor belt 4 to rotate, thereby driving the parts to move below the clamping roller 11. The parts are clamped by the clamping roller 11. Then, start the spraying mechanism and the second motor 23. When the second motor 23 is started, it will drive the rotation of the disc 24. When the disc 24 rotates, it will drive the rotation of the convex block 25. When the convex block 25 rotates, since the left and right movement of the movable frame 26 is restricted, the rotation of the convex block 25 will drive the movable frame 26 to move up and down. When the movable frame 26 moves up and down, it will drive the lifting frame 27 to move up and down. When the lifting frame 27 moves up and down, it will drive the sealing plate 28 to move up and down, thereby continuously discharging the gas inside the pneumatic chamber 20 from the one-way nozzle 21, so as to push the powder to rise to a higher height. Through the cooperation between the first nozzle 16, the second nozzle 17, the third nozzle 18 and the one-way nozzle 21, the powder is sprayed above the parts.

[0026] By starting the motor 23 to drive the disc 24 to rotate, the sealing plate 28 is continuously raised and lowered through the cooperation between the movable frame 26 and the protrusion 25, so that the gas inside the air pressure chamber 20 continuously drives the powder to rise. Compared with the traditional device, the device continuously rises and falls the sealing plate 28, so that the powder sprayed from the one-way nozzle 21 is higher in height and can be evenly sprayed on the bottom of the parts, thereby improving the working efficiency of the device.

When the roller two 35 rotates, it will drive the cleaning wheel two 36 to rotate. When the cleaning wheels one 32 and the cleaning wheels two 36 rotate, the surface of the conveyor belt 4 will be cleaned.

[0029] By starting motor three 30 to drive the rotation of roller one 31 and roller two 35, the cleaning wheel one 32 and cleaning wheel two 36 are respectively driven to rotate.
