In the industrial control industry, in some of the ribbon and linear products, often need to control the tension to achieve production requirements, tension controller is to control the tension of a meter. The tension controller and so-called manual control function, generally refers to human can given a certain amount of tension controller output to the actuator (often current motor); general tension force controller with coil diameter calculation, generally used in coiling equipment, have the unrolling and rolling of another; taper adjustment function, can be directly set by the controller for the process of coiling taper.
A typical tension control system is mainly composed of a tension controller, tension reader, tension detector, magnetic powder brake and clutch structure. According to the ring can be divided into open loop, closed loop or free loop tension control system, according to the monitoring of different coil can be divided into ultrasonic type, floating roller type, tracking arm type, etc..
The stability of tension control is directly related to the quality of the product. If the tension is insufficient raw drift in operation, will appear after slitting and rewinding of finished paper wrinkling; if the tension is too large, raw materials and easy to be broken, the slitting and rewinding after finished paper were increased.
