[0002] In production and life, printed product lamination makes the product more beautiful and has a longer shelf life. People have become inseparable from printed product lamination. Fully automatic laminating machines are common in many fields. At the same time, in order to laminate quickly and with high quality, the film roll needs to be properly heated as required to melt the pre-coated adhesive. With the development of society, pre-coated adhesive film, as one of the processes, has become more and more important for improving work efficiency and protecting the working environment. The use of an electric heating roller system is more environmentally friendly and safe, and the temperature control is more precise, and the speed and quality of lamination are also improved accordingly.

[0003] Since the pre-coated film roll has strict requirements on temperature control accuracy, the temperature, temperature control accuracy, and heating speed directly affect the quality and speed of the film-coated products. The original oil heating method is not easy to control the temperature, the heating is slow, and there is a risk of oil leakage, causing pollution and affecting the quality of the film; the electromagnetic heating method heats up quickly and has accurate temperature control, but the structure is complex and the cost is too high. Therefore, the selection and implementation of the heating method and temperature control method will be the bottleneck of the quality and speed of the film. Utility Model Content
