Daily maintenance and maintenance of the slitter:
First, the electrical parts should be cleaned and inspected regularly to remove hidden dangers in time.
Second, the use of slitting machines is done by slitting machines and cross-cutting machines. Therefore, high-quality slitting cutters and cross-cutting cutters are used.
Third, the daily maintenance of the slitting machine should be in place. The standard is that smooth, clean, clear (no dust, no debris) is in place to ensure that the sliding part of the equipment is in good condition.
Fourth, it is the maintenance work, and the regular and irregular inspections of the rotating parts should be stopped (especially the real-time monitoring of the wearing parts should be stopped). Regular adjustments are made, regular changes are made, commutators are carefully recorded, and the purpose of extending the service life of the equipment is achieved.
Fifth, improve the technical quality and degree of the personnel who operate the slitting machine. The control of the local operation must be done by a special person, and no one can operate it without any permission.
Slitting machine operating procedures -
Third, through the film：
14. Press the “MACHINE” button, the siren will sound and the signal light will flash yellow. Confirm that the personnel are in the safe area, press "machine on" again, the button light is always on, the machine starts and accelerates to the input set speed.
15. If necessary, perform parent roll adjustment, brake tension adjustment, and flattening roller position check at low speed.
Causes, countermeasures and effects on the quality of BOPP film slitting quality ---
(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.
