Description

Technical Field

[0002] Metal composite panels refer to panels with another type of metal covered on a layer of metal. They can save resources and reduce costs without reducing the use effect, anti-corrosion performance and mechanical strength. In the production process of metal composite panels, the metal composite panels need to be sprayed. In order to improve the drying efficiency after spraying, a metal composite panel spraying device with a drying effect is required. When the metal composite panel spraying device with a drying effect sprays the paint on the surface of the metal composite panel, high-pressure gas is used to blow out the paint, so that the paint is sprayed on the metal surface to form a protective layer. Because there is dust in the air, it falls on the surface of the metal composite panel, which will cause the paint surface of the metal surface to form granular protrusions, which not only affects the appearance, but also causes rust and paint detachment after a period of use.
