Through the heating effect of the heating wire, the aluminum plate and the film are directly heated and pressed, and the heating effect is obvious. At the same time, the axis core of the heating laminating roller and the conveying direction of the aluminum plate are set at an acute angle, and the aluminum plate and the film can be effectively bonded during the pressing process. The air bubbles between them can be effectively eliminated to improve the quality of the aluminum plate coating; in addition, the utility model has a simple structure and is easy to use, and the coating process is automated, which reduces the consumption of manpower and working hours and improves production efficiency. After heating and cooling, the film quality is high, and the film is not easy to deform after long-term storage.
