Description

technical field [0001] The invention relates to the field of drying, in particular to a three-stage automobile spraying drying device. Background technique [0002] The car body needs to be sprayed with paint, which not only has a good anti-rust and anti-deformation effect, but also is more beautiful. In the prior art, a baking process is usually used. The baking process is to apply three times of primer and four times of top coat on the base material. , paint each time, and then send it to a dust-free constant temperature baking room for drying. Due to the need for multiple times of drying, the requirements for the drying speed are relatively high. In the drying chamber in the prior art, the drying speed is relatively slow, and the paint smell of the entire drying chamber is relatively high due to the fact that the car body has just been sprayed with paint. Heavy, seriously pollute the environment, and the existing drying room is difficult to effectively remove the paint s...
