A coating machine usually includes a unwinding unit, multiple guide rollers, a coating head, a drying box (or a curing unit), and a winding unit. The material (substrate) continuously runs between these units, and the tension needs to be accurately set and maintained in different sections (such as after unwinding, before coating, during drying, and before winding) according to process requirements. Devices such as gravity rollers, swing arm tensioners, magnetic powder / hysteresis brakes / clutches are used. These devices have relatively simple structures and low costs, but their tension adjustment range is limited, they are difficult to quickly respond to sudden changes in material properties (such as thickness, elastic modulus, and friction coefficient) or large-scale changes in production speed, their tension control precision is not high, and they are prone to performance degradation due to mechanical wear, requiring frequent maintenance. In particular, when dealing with new materials such as ultra-thin, easily stretchable, or high-strength materials, the performance is poor.
