Description

Technical Field

[0001] The utility model relates to the technical field of car cover processing, in particular to a coating machine for car covers. Background Art

[0002] A car cover is a polymer material that is attached to the surface of a car body to protect and change its color. Compared to full-car painting, car covers are simple to apply, have no effect on the vehicle's original paint, have minimal color difference, and are easy to remove. Therefore, they have become increasingly popular in recent years. The production of car covers involves multiple processing steps, including coating, and the coating process is currently carried out in supporting coating equipment.

[0003] Although the existing coating device of the car cover can perform coating operations on the film car cover, it has the following disadvantages: a small amount of fine chips or dust will adhere to the film car cover during the front-end processing process. During the coating process, the coating roller will adhere to the fine chips and bring the fine chips into the coating box. Too much fine chips in the coating box will affect the quality of the coating, and then affect the quality of the film car cover after coating.

[0004] In view of this, this application is hereby filed. Utility Model Content
