[0002] Spraying is a coating method in which, through a spray gun or a disc atomizer, with the aid of pressure or centrifugal force, it is dispersed into uniform and fine droplets and applied to the surface of the object to be coated. It can be divided into air spraying, airless spraying, electrostatic spraying and various derivative methods of the above basic spraying forms, such as large-flow low-pressure atomization spraying, thermal spraying, automatic spraying, multi-group spraying, etc. When metal structural parts are produced, it is necessary to spray anti-corrosion agents on their surfaces, and thus anti-corrosion spraying devices are required.

[0003] For example, the patent document CN216826894U discloses an anti-corrosion spraying device for the metal surface of mechanical parts, including a workbench.
