Description

Technical Field

[0001] The utility model relates to the technical field of plate processing equipment, in particular to an automatic plate painting device. Background Art

[0002] Plates are flat rectangular building material plates made of standard sizes, used in the construction industry to make components of walls, ceilings or floors. They also refer to metal plates made by forging, rolling or casting. For the sake of beauty, plates often need to be sprayed with paint. Spray paint is a kind of artificial paint made of nitrocellulose, resin, pigment and solvent, etc. It is usually sprayed evenly on the surface of objects with a spray gun. It is resistant to water and oil and dries quickly, but the substance is toxic and has a certain impact on the body. Different brands of spray paint have different toxicity due to different content of ingredients. Special attention should be paid to safety when using it to avoid inhalation and skin contact. The following problems exist in the existing technology:
