[0019] The usage process of the present invention is as follows: Add various raw materials of the spraying paint into the storage tank 2, and then control the operation of the second motor 25. The operation of the second motor 25 drives the rotation of the second rotating shaft 19. The rotation of the second rotating shaft 19 drives the rotation of the upper bevel gear 29. The rotation of the upper bevel gear 29 drives the rotation of the first bevel gear 28. The rotation of the first bevel gear 28 drives the rotation of the lower bevel gear 29. In this way, the third rotating shaft 20 and the second rotating shaft 19 can rotate simultaneously.

Furthermore, the second moving rod 38 and the second piston 37 move up and down. Then, under the action of the air pipe 39 and the connecting pipe 35, the up and down movement of the second piston 37 can make the air in the second box 36 and the two first boxes 31 flow back and forth. In this way, the two first pistons 32, the two first moving rods 33 and the pushing plate 30 can move up and down continuously. The up and down movement of the pushing plate 30 can reciprocally push the raw materials. Cooperating with the rotation of components such as the stirring rod 21 can ensure the uniform mixing of the paint raw materials; After the mixing is completed, place the workpiece on the placing block 4, then close the box door 15, then open the switching valve 14, and then control the operation of the pump body 11. Then, under the action of the third pipe 13 and the second pipe 12, the paint can enter the first pipe 5, and finally be sprayed on the workpiece through multiple atomizing nozzles 6, thus realizing spraying. While spraying, control the operation of the first motor 16. In this way, the first rotating shaft 17 and the placing block 4 can rotate, so that the workpiece rotates, and thus uniform spraying is realized. In addition, two camera bodies 8 are designed, and a display screen 10 electrically connected to the camera bodies 8 is also designed. In this way, when spraying, the display screen 10 can display the images captured by the camera bodies 8 in real time.
