Tension Control Instrument

In many paper mills, color printing plants, weaving and dyeing factories, wire and cable factories, metal foil processing plants, etc., the tension control instrument is used to process some paper, cloth, wire, metal foil, film, etc. Instruments for tension control of materials and products when receiving and discharging.

A complete tension control system with basic components including controller, clutch and brake. The tension controller can be divided into manual control and automatic control. The manual controller, that is, the steady current power supply, manually adjusts the excitation current of the clutch or brake according to the change of the receiving material or the discharge coil diameter, thereby obtaining consistent tension and automatic tension control. The tension detector is used to directly measure the tension of the coil, and then the tension data is processed to automatically adjust the excitation current of the clutch or brake to control the tension of the coil.

Unwinding: The tension of unwinding is controlled by the braking torque of the magnetic powder brake in the unwinding device. As the winding diameter of the winding is continuously reduced, the braking torque must be continuously reduced. The tension detector is used in the figure. The tension of the winding is detected, and the torque of the magnetic powder brake is automatically controlled by the tension controller to make the tension constant. Winding: The winding speed is normal faster than the material's linear speed, so the magnetic powder clutch works in the slip state, and the tension is controlled by the torque of the magnetic powder clutch. In order to keep the tension constant, it must be increased or decreased according to the size of the winding diameter. The torque of the magnetic powder clutch.
