In industry, the stability of tension control is directly related to the quality of the product. If the tension is insufficient, the raw materials will drift during operation, affecting the quality of the finished product. If the tension is too high, the raw material will be easily broken, which will increase the scrap rate. The tension controller consists of a magnetic powder brake, a clutch, and a tension detector, and plays an important role in the tension control system.

As a relatively high-precision tension output device, three basic control methods are used when controlling tension. The first basic tension control method is the manual control method. During control, the torque is manually adjusted according to the unwinding and rewinding conditions to obtain the required tension. The advantage of this kind of manually controlled equipment is that it can save energy during operation, and it can also perform more flexible operations under low-speed conditions, such as performing emergency control when the machine is stopped, or remotely operating the adjustment knob during operation. . However, manual tension control has many limitations when it comes to unwinding, rewinding control or intermediate shaft control where the speed is relatively fast and the roll diameter changes greatly.

The second control method is semi-automatic control method. This kind of equipment requires the use of ultrasonic principles when operating. When actually controlling the tension, the tension controller adopts a semi-closed loop method to control, and can ideally adjust the output torque, and can also prevent special situations such as loosening and breakage. This semi-automatic tension control method has a wide range of applications in the mechanical field due to its low cost. Next there is a fully automatic control method. This control method is relatively high-tech. Under this tension control mode, sensors are installed inside the machine. These sensors are operating at any time, capturing various operating parameters at any time, and then directly analyzing the parameters through a microcomputer. Accurate control, in high-speed operation mode, this fully automatic control method is very popular.

Senming Industrial's fully automatic multi-functional tension controller and intelligent tension controller have advanced multi-level PID parameter adaptive programs to achieve fast response and precise control. It is suitable for various tension control schemes, equipped with advanced communication functions, rich external joint control ports, simple operation and powerful control functions.
