During the spraying process, the battery pack 12 drives the clamping clamp 3 to rotate the workpiece through the rotating sleeve, so that the workpiece can be sprayed evenly. The front end of the spraying box 2 is symmetrically provided with two sets of box doors 10. The two sets of box doors 10 are connected to the spraying box 2 by a movable sleeve at one end away from each other. The two sets of box doors 10 are movably connected to the spraying box 2 through the movable sleeve. By combining the two sets of box doors 10, the operator can rotate the box doors 10 through the movable sleeve during spraying, thereby closing the spraying chamber 201 and preventing the exhaust gas from spraying from splashing to the outside.
[0023] Please see Figures 2-3 In this embodiment, the upper two side walls of the support frame 14 are provided with positioning slots 15 for fixing the paint can 901. Each of the two sets of positioning slots 15 has a pipe outlet 16 at its center. A receiving groove 17 for accommodating the paint can 901 is provided between the two sets of positioning slots 15. A secondary through hole 18 is provided on one side of the bottom of the support frame 14. A primary through hole 13 corresponding to the secondary through hole is provided on the top of the spray booth 201. By combining the support frame 14 with the positioning slots 15, the paint can 901 can be fixed in the receiving groove 17 via the positioning slots 15 during installation, avoiding… The paint-free can 901 can be rolled freely. The rear side wall of the waste paint collection bin 501 has a three-stage through hole 19. The front end of the waste paint collection bin 5 has an insertion port 7. Inside the insertion port 7 is a filter plate drawer 8. The bottom of the filter plate drawer 8 has multiple sets of drainage holes 6.

[0029] Through the above steps, this application combines the spraying box 2, the waste paint collection box 5, and the spraying mechanism 9. During spraying, the paint flows out of the paint tank 901 through the paint delivery pipe 903, passes through the outlet 16, the secondary through hole 18, and the primary through hole 13, and finally reaches the spray head 904 at the top of the spraying chamber 201 for spraying. During the spraying process, the battery pack 12 drives the clamping clamp 3 to rotate the workpiece through the rotating sleeve, so that the workpiece can be sprayed evenly. Excess paint on the workpiece and some paint mist that fails to adhere to the workpiece will naturally sink or be guided by the airflow to the collection hopper 4, and enter the waste paint collection chamber 501 from the collection hopper 4. The filter plate drawer 8 is inserted into the waste paint collection chamber 501 through the insertion port 7 to filter out impurities and particles in the waste paint, ensuring the quality of the collected waste paint.
