How to solve the situation that the slitting machine produces noise during operation?

First check whether the installation position of the knife belt is correct, and check the levelness of the knife belt;

Then check whether the surface of the cutter wheel is too rough;

If there is no problem with the above, then you need to check to see if the knife belt is tightened. If not, you need to tighten the knife belt. The forward and reverse rotation of the knife belt should be based on the middle of the knife wheel;
