The work of High Speed Paper Roll Slitting Machine is mainly to play the effect of slitting. It is also very accurate for paper slitting and textile slitting. We know that equipment may be scratched during work. For this Phenomenon, we also need to find the reason. Let’s talk about the cause of the scratches during the work of the cutting machine.
1. Scratches caused by unreasonable settings.
The main situations include: during the operation, the loose steel coils will be re-tightened when unwinding on the machine, resulting in scratches. When the back tension applied by the rewinder is greater than the coiling tension of the base material, or the pressure of the stop roller is insufficient, or the brake applied by the rewinder is insufficient, it will cause the steel coil to slack and cause scratches. Once the back tension is too large, the steel plate will suddenly tighten when it is pulled and loosened, and scratches will also occur. Therefore, measures should be taken to reduce the braking force of the rewinder when the work is over.
2. The slitting machine is scratched due to improper setting.
After shutdown, it is easy to loose the coil during the restart process. The shearing slack of the outer ring, the lateral displacement of the coil during the unwinding process, etc., may cause scratches. In addition, coiling scratches will appear when straight-pull shears and loose steel coil ferrules are rewinded.
