[0004] The device mainly has a fixing part for fixing the workpiece on the conveyor chain, which moves within the limit part of the conveyor chain limiting frame. The limit part limits the left and right swing of the fixing part, and cooperates with the rotating device arranged on the machine body. The rotating device drives the fixing part to rotate, and the workpiece dipped in paint is hung on the fixing part, so that the workpiece is rotated, and the excess paint is thrown out by centrifugal force. Because the centrifugal force generated by the rotation is uniform, it can ensure that the force on the workpiece is uniform, so the paint on the surface of the workpiece after painting is uniform and the painting effect is beautiful. However, the device does not have a structure to prevent the paint from splashing. When the paint is thrown out, the paint is subjected to the impact force and its excess tail material will be splashed. The splashed paint will not only pollute the surrounding environment but also cause waste of paint.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original external coating machine structure. Utility Model Content
