Description

Technical Field

[0001] The utility model relates to the technical field of plastic spraying equipment, in particular to a metal surface uniform plastic spraying equipment. Background Art

[0002] The metal surface processing technology includes spraying plastic on the metal surface, which creates a protective film on the metal surface. Compared with ordinary paint surface treatment, the color of spraying plastic is more vivid and more popular with users.

[0003] At present, the working principle of plastic spraying equipment is to spray plastic coating powder onto the surface of the workpiece through a nozzle. The powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating. The powdery coating on the surface of the metal component will then be leveled and solidified after high-temperature baking. The plastic particles will melt into a dense final protective coating with different effects, which will firmly adhere to the surface of the workpiece.

[0004] However, the existing metal surface uniform spraying equipment still has shortcomings:

[0005] It is difficult to adjust the positioning height and angle when positioning the metal workpiece. After positioning metal workpieces of different sizes, the distance between the metal workpiece and the spray head is different. If the metal workpiece is larger, the distance will be smaller. However, the smaller distance will affect the spraying effect. However, if the positioning height cannot be adjusted, it is difficult to automatically adjust the distance, which will affect the spraying effect. If the positioning angle cannot be adjusted, it will be difficult for the spray head to fully spray all angles of the positioned metal workpiece, which will affect the uniformity of the spraying.

[0006] Therefore, we have made improvements to this problem and proposed a device for uniformly spraying plastic on metal surfaces. Utility Model Content
