[0065] Brief description of the use process: When in use, the paint powder enters the material pipe 13 through the hopper 12 and is discharged into the top of the inspection and discharge plate 42. The drive motor 51 starts to drive the rotating rod 52, flip the dredging plate 54 and the pressure plate 1 53, and drives the pressure plate 2 63 to rotate under the action of the guide groove 16 and the guide block 17. When the pressure plate 2 63 rotates, the electric push rod 61 is connected to the annular slide groove 64 through the slider 62. Therefore, the electric push rod 61 does not change its position when the pressure plate 2 63 rotates;

[0066] When the pressure plate 2 63 and the pressure plate 1 53 rotate, they will push the inspection plate 42 alternately. No matter whether the pressure plate 2 63 or the pressure plate 1 53 pushes the inspection plate 42, the inspection plate 42 will drive the two connecting posts 4301 to rotate. The connecting post 4301 will drive the pressure block 4302 to squeeze and compress one of the two first springs 4304 in the fixing ring 4303 under the guidance of the guide groove 4305. When the pressure plate 2 63 separates the pressure plate 1 53 and the inspection plate 42, the squeezed and compressed first spring 4304 will push the pressure block 4302 to drive the connecting post 4301 to rotate and reset, thereby resetting the inspection plate 42. By alternately flipping the two sides of the inspection plate 42, the coating powder can be screened. Large particles of powder will remain on the top of the inspection plate 42, while qualified powder will be discharged downward through the inspection plate 42 and discharged by the guide plate connecting piece 73 to the connecting plate 71;

[0067] If you need to screen different sizes of paint powder, you can replace the connecting piece 73 with a filter plate to screen the paint powder to different sizes. The paint powder of two sizes can be guided out through the guide plate 72 and the connecting plate 71.

[0068] After the material is screened, the remaining large particles of powder are in contact with the second pressing plate 63 and the inspection and discharge plate 42. The electric push rod 61 is activated to push the second pressing plate 63 toward the material pipe 13. Under the pushing action of the second pressing plate 63, the inspection and discharge plate 42 will be greatly flipped until one side of the inspection and discharge plate 42 is separated from the inner shell 2 to form a discharge port. At this time, the large particles of powder can be discharged into the interior of the receiving bin 81 through the discharge port. After that, the electric push rod 61 drives the second pressing plate 63 to return to its original position and the second round of screening is carried out.

[0069] After the material enters the receiving bin 81, workers can adjust the size of the powder grind in advance as needed; by rotating the handle 1164, the rotating rod 1163, the second bevel gear 1162, the first bevel gear 1161 and the screw 111 are driven to rotate, and the screw 111 drives the threaded block 112 to drive the connecting plate 113, the connecting tube 101 and the connecting rod 1 8501 to move up and down, thereby driving the grinding plate 83 to move up and down through the connecting rod 1 8501. By changing the distance between the grinding plate 83 and the grinding seat 82, the grinding size of the grinding plate 83 and the grinding seat 82 can be changed;

[0070] When the second round of screening begins, the rotating rod 52 is driven to rotate by the driving motor 51, and the rotating rod 52 also drives the second bevel gear 8504 to rotate, the second bevel gear 8504 drives the first bevel gear 8503 to rotate, the first bevel gear 8503 drives the connecting rod two 8502 to rotate, the connecting rod two 8502 drives the connecting pipe 101 to rotate under the action of the slide block 102 and the slide groove 103, the connecting pipe 101 drives the connecting rod one 8501 to rotate, and the connecting rod one 8501 drives the grinding disc 83 to rotate, so that the device can be used for screening, and the large-particle coating received by the receiving bin 81 can be ground, and the ground coating can be directly discharged through the discharge pipe 86.
