Description

Technical Field

[0001] The utility model relates to the technical field of metal parts surface treatment equipment, in particular to a coating spraying and drying equipment. Background Art

[0002] Dacromet is an anti-corrosion process applied to metals. After Dacromet coating is applied to the metal surface, it is baked at high temperature by a drying mechanism to form a thin protective layer to prevent the metal from rusting. The drying mechanism usually uses a conveyor belt to heat and dry the workpiece to be processed at a fixed speed. The conveyor belt is a metal mesh belt, and the uncured paint on the workpiece will drip onto the metal mesh belt during the conveying process. After being heated by the drying mechanism, paint spots will form on the metal mesh belt, which need to be cleaned in time.

[0003] At present, the metal mesh belt is generally cleaned manually with a wire brush after the machine is shut down. This is not only time-consuming and laborious, but also difficult to control the strength of manual processing. Sometimes the strength is light and sometimes heavy. If the strength is too light, the paint stains cannot be completely removed, which prolongs the cleaning time. If the strength is too heavy, the metal mesh belt will be worn and the service life of the metal mesh belt will be reduced. In addition, the shutdown will also delay the operation, causing production delays and energy consumption losses. Therefore, a paint spraying and drying equipment is proposed to solve the above problems. Utility Model Content
