Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, and more specifically, to a powder spraying room. Background Art

[0002] Powder spraying of automotive parts is a common surface coating process used to give automotive parts ideal appearance and performance characteristics. Electrostatic powder spraying equipment is used to evenly spray powder coating on the surface of parts. Powder coating is usually a powdery substance composed of pigments, resins and additives. Different colors and materials can be selected as needed.

[0003] In the existing technology, the existing powder spraying room cannot efficiently filter the air supplied when supplying air, resulting in dust directly entering the powder spraying room, affecting the quality of coating, and cannot be cleaned conveniently through the filtering device, which reduces the practicality of the air inlet pipe. In the process of powder spraying on the workpiece, when the powder adheres to a certain thickness, under the repulsive effect of the same polarity charge, the workpiece surface no longer absorbs the powder, and the excess powder floats in the air in the powder spraying room. When the powder spraying room is opened, some dust easily flows into the air outside the powder spraying room, causing pollution to the surrounding environment. Utility Model Content
