The lacquer dipping box 2 supports the feed box 3 and two connecting air pipes 31, and the feed box 3 supports two fans 32. The two fans 32 guide and drive the airflow. When the material loading net plate 13 drives the coil inside the feed box 3, the airflow driven by the two fans 32 blows the coil on the material loading net plate 13, so that the dust impurities and water vapor particles attached to the coil can be blown away. Cleaning, the paint dipping box 2 contains air through the ventilation inner groove 21. After the internal heating equipment of the paint dipping box 2 heats the paint, the heat is transferred into the ventilation inner groove 21 to heat the air.
