Secondary basecoat paint, its advantage is that the coating quality of priming paint is improved, spraying effect of the finishing coat on priming paint is also further mentioned
Height totally improves the painting quality of car trim；
Again, the present invention improves the suction mist structure in painting process, because inhaling mist structure is in painting process than heavier
The structure wanted will certainly generate the more coating cloud not being utilized in robot painting process, if these coating clouds are too late
When be collected processing if can not only pollute influence to the environment of paint spray booth, but also be unfavorable for coating cloud and collect faster
Processing application, will cause the waste of material, although the existing suction mist having using cascade structure, structure is designed to be tied from spray painting
Farther out, while cascade is single-sided structure to structure, can only absorb the coating cloud close to the cascade side, not thorough enough to the absorption of coating cloud,
Therefore, the present invention devises umbrella shape mist arrester 7, and umbrella shape mist arrester 7 can not only realize that enclosed thoroughly inhales mist purpose, but also
The automation that mist area size can be carried out inhaling for products of different specifications is adjusted, reasonable in design, operates convenient, adjusting side
Just.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
