This equipment is widely used in a variety of applications, especially in the fields of traffic signs, road markings, vehicle signs and safety signs. Its main function is to ensure a strong bond between the reflective film and the substrate to provide a lasting reflective effect and durability.

[0003] After searching, the existing patent (Announcement No.: CN213876219U) discloses a reflective film laminating device for a light guide plate for a backlight source, including an integral structure of a laminating frame, wherein the integral structure of the laminating frame includes a laminating U-shaped frame, a laminating handle is arranged at the center of one side of the laminating U-shaped frame, and a reflective film pressing roller is arranged on the inner side of the laminating U-shaped frame, and a pressing roller cotton cloth cover is wrapped on the outer side of the reflective film pressing roller, a reflective film scraper is arranged on the back side of the laminating U-shaped frame, and one side of the laminating U-shaped frame is provided with a laminating handle, and a reflective film pressing roller is arranged on the inner side of the laminating U-shaped frame.
