Analysis of the causes of the film roll of the slitting machine that is too loose and too tight

1. Influence of slitting machine parameters:

Unwinding tension, rewinding starting tension, pressure and curve setting factors, etc.;

2. Influence of film characteristics:

Under the influence of film thickness, haze, roughness, shrinkage and other factors, the slitting parameters must be set according to the film with different characteristics;

3. Influence of winding speed:

When the winding speed is slower, the more time the slitting process has to expel the air in the film roll, the tighter the film roll will be winded;

4. Influence of product specifications:

winding length, rolling, etc.;

5. Influence on the performance of slitting equipment:

adjustability, stability, operability, etc.;

6. Influence of operating factors:

Professional level, operation skills, sense of responsibility, etc., are generally manifested in the quality of work such as inserting the wrong steam pipe, poor adjustment of the position of the winding chuck, and unbalanced winding pressure roller;

7. Influence of environmental factors:

temperature, humidity, etc., shall not open the door of the clean room arbitrarily;

8. Influencing factors of the assessment system:

Considering the assessment of the slitting index in the workshop, the operator often adopts the coping method of winding rather tight than loosening, which is one of the factors causing the film roll to be too tight.
