Description

Technical Field

[0001] This application relates to the technical field of metal products, and particularly to a spraying device for metal decorative parts. Background Art

[0002] Metal decorative parts refer to decorations processed from metal raw materials into various shapes, patterns, and textures through processes such as casting, forging, welding, and cutting. Such decorative parts not only have an aesthetic appearance but also possess advantages such as durability and easy cleaning due to the characteristics of the metal material. With the improvement of people's living standards and the change of aesthetic concepts, the market demand for metal decorative parts is increasing continuously.

[0003] To meet different market demands, metal decorative parts need to be sprayed during processing. The traditional spraying of metal decorative parts is to clamp the metal decorative parts and then spray. For spraying different surfaces of the metal decorative parts, it is necessary to re-fix them after contact limiting, which is rather troublesome to operate. Moreover, due to the gravitational effect after spraying, the paint will flow downward, resulting in uneven spraying and affecting the quality of the finished product. Therefore, to solve the above problems, this application provides a spraying device for metal decorative parts.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content
