[0002] In the field of metal processing and surface treatment, metal sheet lamination technology has developed rapidly in recent years due to its unique performance advantages and broad application prospects. This technology not only enhances the corrosion resistance and wear resistance of the material by compounding one or more layers of plastic film on the surface of the metal sheet, but also gives it richer colors and textures, thereby meeting the high requirements of the appearance and performance of the material in many industries such as construction, home appliances, and transportation. However, in the production process of metal sheet lamination rolls, tension control is a crucial link. The size and stability of the tension directly affect the quality of the lamination, the flatness of the product and the processing efficiency. If the tension is not properly controlled, it is easy to cause wrinkles, breaks, offsets and other problems in the lamination, which seriously reduces the qualified rate and market competitiveness of the product. The traditional metal sheet lamination tension control method mostly relies on the operator's experience and manual adjustment, and has problems such as low adjustment accuracy, slow response speed, and low degree of automation. Especially on high-speed and continuous production lines, these problems are more prominent and it is difficult to meet the high requirements of modern industrial production for product quality and efficiency.

One end of the bottom short rod is rotatably fixed to one side of the bracket fixing plate 4 through the rotating shaft, and one end of the top short rod is rotatably fixed to the inner wall of the groove arranged at the bottom of the lifting platform 2 through the rotating shaft. In this way, the lifting platform 2 can be raised and lowered, thereby adjusting the height of the coating roll 10.
