The magnetic powder brake of slitter mainly provides balanced and stable torque. The torque is adjusted by tension controller to improve the efficiency and quality of slitter unwinding and the whole operation.
The tension control of slitting machine is basically manual tension control and automatic tension control. So you know how to adjust the tension of slitter correctly?
1. Full automatic tension control is to directly measure the actual tension value of the strip by the tension sensor, and then convert the tension data into a tension signal to feed back to the tension controller. By comparing this signal with the preset tension value of the controller, the control signal is calculated, so that the actual tension value is equal to the preset tension value, so as to achieve the purpose of stabilizing the tension.
2. Manual tension control means that in the process of winding or unwinding, when the winding diameter changes to a certain stage, the operator adjusts the manual power supply device, so as to achieve the purpose of tension control.
The tension setting of slitting machine directly affects the yield of the product. The tension is too large and the winding is too tight. The aluminum foil is prone to wrinkles. I. the tension is insufficient. The aluminum foil is prone to slip on the roll and seriously misplace the shaft, which makes it impossible to unload the roll. As a result, the unwinding of the roll during slitting produces a large swing, which affects the slitting quality. The slitter needs a good tension detection system.
