Nowadays, many paper slitting machines will encounter such a problem during use. That is, there is insufficient tension in the paper slitting opportunity. How should we solve this situation?
         When the voltage of the upper and lower tension controllers that control the magnetic powder clutch of the paper slitter is adjusted to a high level, the winding tension is still insufficient and the winding film is loose. At this time, we can easily grasp the winding shaft by hand and stop it Turn. This shows that the output torque of the magnetic powder clutch of the high-speed cutting machine is insufficient. The reason is that the magnetic powder in it is reduced or failed due to the long time. Then you can continue to work normally.

        After reading the above, I believe everyone already knows the solution to the lack of tension in the paper slitter.
