Maintenance and maintenance of the slitter:
Before use, the main parts of the automatic slitting machine should be inspected and filled with lubricating oil. When inspecting the disassembly and assembly automatic slitting machine, it is strictly forbidden to use unsuitable tools and unscientific operation methods; every two weeks to the machine Make a comprehensive cleaning and inspection; if the automatic slitting machine is stopped for a long time, all the bright surfaces must be wiped clean, coated with anti-rust oil, and covered with a plastic sleeve to cover the whole machine. If the automatic slitting machine is deactivated for more than 3 months, the anti-rust oil should be covered with moisture-proof paper; after the work is completed, carefully clean the equipment, and wipe the exposed friction surface and add lubricant.
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.
