Slitting Rewinding Machine For Skotch Tape

Slitting Rewinding Machine For Skotch Tape

Tape slitter setting control:
1. Set the slitting menu according to the type, thickness, length, width, etc. of the film arranged in the slitting plan.
2. Lift the corresponding BOPP film file from the PDF.
3. Set the winding length and width of the film of the corresponding specification.
4. Select the corresponding winding station, adjust the pressure roller arm and pressure roller, and install the paper core of the corresponding specifications.

Causes, countermeasures and effects on the quality of BOPP film slitting quality ---

(3) Causes of loose/overtightening of the film roll
1. The influence of the cutting parameters (winding sheet / pressure curve setting factors, etc.);
2. Effect of film properties (stiffness, thickness, single/double corona surface, smoothness, static electricity, etc.)
Ringing, the slitting parameters must be set according to the film with different characteristics);
3. The effect of the winding speed (when the winding speed is slower, the more time the slitting process is to discharge the air in the film roll, the tighter the film winding is);
4. Product specifications (width, length, collocation, etc.);
5. The influence of the performance of the slitting equipment (adjustability, stability, operability, etc.);
6. The influence of operational factors (professional level, operational skills, job responsibility, etc., generally expressed in the insertion
7. The quality of the work is wrong, such as poor air-suction, rewinding card head position, poor adjustment, and unwinding roller pressure; The influence of environmental factors (temperature, humidity, etc.);
8. Influencing factors of the appraisal system (Operator considers the appraisal of the secondary processing and rewinding indicators in the workshop, and often adopts the coping method of winding up and not loosening, which is one of the factors that cause the film roll to be over-tightened);

(iv) Effect of film roll tightness on product quality

2. The volume is too loose:
1 Shift: Due to the looseness of the winding, the film roll is easy to move in series and shifts. If the degree is serious, it cannot be used.
2 Core-pulling: Due to the looseness of the winding, the film roll has serious end face misalignment near the paper tube during the loading or unloading or use process, commonly known as “core pulling”, which affects the appearance and use effect of the product.
3 The film wrinkles produced by the loosening of the rolls and the pit lines (stars) formed by the tightness of the inner pines affect the appearance quality and the use effect of the products to some extent.
4 Face wrinkles: Due to the looseness of the winding, the point support force of the end face of the film roll during the movement is reduced, and the fish scale-like end face wrinkles are easily generated.
5 Eccentricity: If the winding is too loose, the film roll will be eccentric (elliptical), and the unwinding tension will be uneven during the unwinding process, which will affect the use effect, especially the printing overprinting effect.
