The precision and response speed of servo tensioner are analyzed

The yarns are output on different diameter surfaces of the cone, and the servo tensioner can produce throughput of different lengths. If the output process is axial continuous change, then the output yarn length is also linear continuous change. The servo tensioner change in jacquard knitting is inevitable and can be used. A component is used to drive the change of yarn position on the feeding cone feeding wheel with the change of yarn tension, so that the output of yarn changes with the change of yarn tension, and then achieve the dynamic balance effect of yarn tension and yarn output.

Servo tensioner rolling usually consists of the middle mill of the on-line bar mill, the tandem frame of the hot strip roughing mill and the first three of the finishing mill. Compared with the looper support, the micro-tension control can improve the control precision and responsiveness of the inter-stand tension, meet the needs of the mill variety and specification, and reduce the maintenance workload and production cost. The controller adjusts the brake or clutch according to the detection signal, thus keeping the tension of the coil constant. The servo tensioner, also known as the coil check out tension controller or the open wave tension controller, adjusts the tension of the coil by detecting the change of the coil diameter.
