The design of material winding system based on tension control

The quality of tension control directly affects the quality of winding products. The quality of tension control directly affects the quality of winding products. At present, most winding systems adopt indirect tension control with dancing roller to meet the requirements in structure, cost and accuracy. Aiming at this goal, this article designs a direct control system based on Siemens 314 PLC and S120 frequency converter by analyzing the winding process and mathematical modeling of tension control. This system adopts a direct closed-loop tension control scheme and converts the tension problem into the control of motor speed. This tension control system has a very friendly man-machine dialogue interface, convenient operation and high reliability, which significantly improves the control accuracy of material winding tension and can be widely used in the actual production of material winding industry.
