The tension controller is a high-precision instrument with digital, automatic control for web tension. It can be widely used in tension control of the printing, packaging, paper, textile and dyeing industries. Web tension controller adopts the CPU of 16-bit or 32-bit, with high speed, high precision, high reliability.
A typical tension control system is mainly composed of a tension controller, a tension reader, a tension sensor, a magnetic powder brake, and a clutch. Depending on the loop, it can be divided into types of open loop, closed loop or free ring. According to the monitoring method of different coils, it can be divided into types of ultrasonic, floating roller, tracking arm. The stability of tension control has directly affected the quality of the slitting products. If the tension is insufficient, it will generate drift in the raw materials moving and the finished paper wrinkle will appear after the rewinding. If the tension is large, the raw material is easily broken, so that the finished products will appear more broken ends after the rewinding.
The tension controller refers to the durable control of the tension performance when the feedstock is stored on the device. This control is required to be valid for any operating speed of the machine, including the deceleration, acceleration, and uniform speed of the machine. Even in emergency parking conditions, it should be guaranteed that the parties are not damaged.
The automatic tension controller is a control instrument that can directly set the tension value of the controlled machine, then directly output the signal of the tension sensor as a tension feedback value, after the proposed bias, outputting to the PID controller for disposal. Then input to the core executive agency to control and finally arrives the purpose of a small bias.
