When the PET protective film needs to be evenly coated, the PET film is pulled to the bottom of the coating component, and the cylinder is started. The output end of the cylinder drives the extension rod to extend the fixedly connected coating box, and the PET material is extended to the coating roller below, which can drive the coating roller to rotate. Under the support of the support shaft, the coating roller is driven to rotate inside the hole groove set below the coating box. In the gap of rotation, the paint inside the coating box is adhered to the coating roller, and then rotated out through the gap to coat the PET protective film attached below, so that it can be evenly coated, improve the use of the PET film, and improve practicality.

[0024] Specifically, in the process of placing the PET protective film, the core components include a moving plate 2 4 and a moving plate 3 6. The function of these two moving plates is to carry the PET protective film. The moving plate 3 6 can be moved by an electric slide rail 7, and the moving plate 2 4 is driven by the moving plate 3 through a slide rod 10, and the moving plate 3 is driven by an electric slide rail 2 9.
