When performing the spraying operation, place the workpiece horizontally on the conveyor belt 7. The conveyor belt 7 drives the workpiece from right to left into the spraying chamber 1. First, compressed air is injected into the air spray head three 23 through the compressed air pipe 22 inside the support frame 10 on the left side of the interior and sprayed onto the surface of the workpiece to remove the dust on the surface. The dust is adsorbed by the static electricity rod 24 and then blown into the cross-flow fan 8, and then blown out through the dust outlet hole 9 by the cross-flow fan 8. After passing through the paint sprayed by the first main spray head 20 and the second secondary spray head 21, driven by the conveyor belt 7, the compressed air blown out by the air spray head three 23 in the support frame 10 on the left side accelerates the solidification of the paint.
