Description

Technical Field

[0001] The utility model relates to the technical field of coating, in particular to a metal steel pipe paint spraying device. Background Art

[0002] The metal steel pipe painting device is a device used to spray paint on metal steel pipes. It is often used in industrial production to achieve anti-corrosion, aesthetic and decorative spray treatment on the surface of metal steel pipes. Through spraying, the entire metal steel pipe surface can be quickly and evenly coated, improving production efficiency and ensuring the quality and consistency of the coating.

[0003] During the painting operation, the existing paint spraying device has a non-stop control, which causes the same part of the metal pipe to be painted repeatedly, resulting in a waste of paint. The paint spraying device usually requires multiple controllers and drive devices to cooperate to control the painting process and the rotation of the metal pipe, resulting in high equipment costs. Therefore, we propose a metal steel pipe painting device to solve this problem. Utility Model Content
