Abstract: In the production process of modern thin film equipment, tension control is a crucial aspect,
and its stability directly affects the quality and production efficiency of thin film products. With the continuous
improvement of process requirements for thin films and other products, traditional tension roller control
methods have become difficult to meet the needs of all control scenarios, while floating roller tension control
technology can effectively address the control requirements that traditional tension roller control cannot
achieve. This article focuses on introducing several structural designs of floating tension rollers and discusses how
to achieve precise control of floating tension through the combination of PLC control system and adaptive
