What are the control methods of the tension controller?
Release Time：
23 Jun,2025
Manual control involves continuously adjusting the torque of the clutch or brake during material feeding, discharging, or processing to achieve the desired tension. This requires the user to constantly check the tension of the controlled material and adjust the output torque. When using pneumatic brakes or clutches, a precision pressure regulator can be directly used as the manual controller, saving equipment costs. However, this is only suitable for low-speed composite machines, extruders, textile machinery, and other applications with low tension control requirements.
1. Manual Control: Continuously adjusting the torque of the clutch or brake during material feeding, unwinding, or processing to achieve the desired tension. This requires the user to constantly check the tension of the controlled material and adjust the output torque. When using pneumatic brakes or clutches, a precision pressure regulating valve can be directly selected for the manual controller, saving equipment costs. However, this is only suitable for low-speed composite machines, extruders, textile machinery, and other applications with low tension control requirements.
2. Semi-automatic Mode: Utilizing proximity switches and other sensors to automatically detect the number of rotations and adjust the winding tension. For example, the AB7880A semi-automatic tension controller from Aibo Zhikong Company is essentially a semi-closed-loop tension control system. It can automatically measure the winding, control torque output, and has functions such as buffer start, slack prevention, and inertia compensation. This solution has a relatively low implementation cost and is widely used in mid-range machinery.
3. Fully Automatic Mode: Generally, there are two detection methods. One is to determine the tension of the material through a tension sensor, and then the controller automatically adjusts the clutch or brake to control the winding tension. This method is a closed-loop tension control. In principle, this scheme can reflect the changes in tension in real-time, thus achieving the highest control accuracy. Therefore, high-end precision rolling mills, high-speed slitting machines, and other metallurgical applications use fully automatic tension control systems.
