Common faults and troubleshooting methods of slitting machine

How to maintain the slitting machine?In the daily production process, there are some problems with the slitting machine, so what are the main problems? What will be the impact? Let's take a look.

1. Wrinkles at the bottom

This problem only occurs at the beginning of the winding length and is mainly manifested by wrinkles and deep streaks, which are caused by a variety of factors.

2. The length is not enough, the width is too large

This quality problem is caused by the wrong number of winds or insufficient cut film length, as well as incorrect positioning of the equipment.

3. Longitudinal stripes

Its main manifestation is the formation of annular ribbed stripes on the surface of the film roller. In the slitting and winding process of the slitting machine, a large number of air clamps and cumulative thickness tolerance differences are the main reasons for the occurrence of longitudinal fringes, and it is difficult to eliminate once the more serious streaks appear.

4. Cramps

This quality problem is caused by the accumulation of thickness tolerances and the formation of significant protrusions on the surface of the roll rolls.

5. Distort the edges

This quality problem occurs at the edge of the winding, which is caused by the build-up of thick film edges due to the winding.

6. Split-level

It refers to the phenomenon that the end face of the film roller is not partially filmed, which is mainly caused by the sliding of the film or the change of film width during the winding process.
