Description

Technical Field

[0001] The utility model relates to a spraying device, in particular to a plastic powder spraying device with uniform spraying, belonging to the technical field of plastic powder spraying. Background Art

[0002] Plastic powder is the material for the plastic spraying process. Simply put, plastic powder is heated at high temperature and then sprayed onto the surface of the material by the air given by compressed air. Plastic powder and paint are two different processes. The plastic spraying has good effects, low cost, correct colors, and good aesthetics. Paint is expensive and has general effects. Only polyester paint or fluorocarbon paint can have better effects. Windows and doors are generally used in environments with relatively low corrosion, and the sealing of plastic is sufficient. Paint is used in environments with relatively high corrosion. Finally, the coating of the plastic sprayed product is difficult to repair after being damaged, while paint is relatively easy to repair.

[0003] Chinese Patent Publication (CN202223385164.X) discloses an all-round electrostatic spraying device, which is provided with three hooks for hanging workpieces, and a reciprocating rotation mechanism is provided to drive the turntable to rotate reciprocally, reducing the number of times of adjusting the position of the workpiece during the electrostatic spraying process, so that the spray gun installed on the inner wall of one side of the box can spray the workpiece all-round. However, when this application is used, there is a lack of measures to straighten the workpiece, and the workpiece is prone to shaking during rotation, resulting in poor local spraying effect, affecting the spraying uniformity, and the plastic powder spraying range is large, resulting in some scattered plastic powder not being effectively adhered to the workpiece, causing paint waste.

[0004] To solve the above technical problems, a plastic powder spraying device with uniform spraying is proposed. Summary of the Utility Model
