Simple Adhesive Tape Slitting Rewindng Machine

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.

(iv) Effect of film roll tightness on product quality

(5) Coping methods
1. Reasonable principle: Applicable is reasonable, which means that the cutting operator and the quality inspector are too loose according to the winding/
Too tightly influence the degree of influence on different products, adjust the cutting process reasonably, and reasonably grasp the tightness of the film roll to meet the requirements of the use of film products.
2. Ningsong Motight principle: objective when cutting equipment status, product specifications, film performance characteristics, etc.
When the influence of the condition causes the winding tightness to be in an inappropriate degree, the principle of tightness is generally used, because the problem of over-tightening often makes the film unusable, except for the special requirements.
3. The principle of primary and secondary: it means that in the process of slitting production, small groups should be followed to the interests of large collectives.
The principle of benefiting the interests of the company, avoiding the pursuit of high output and high distribution for the purpose of reducing the quality of cutting, all should be based on product quality, maintaining the German crown film brand as the responsibility, effectively completing various production and quality indicators Effectively serve the enterprise and users, and strive to be the best supplier of film.
4. System Management Principles: Refers to the use of systematic, scientific management methods, practical, theoretical, and empirical
The accumulated cutting control method is compiled, and according to the optimal combination of different types of products, width, winding length, season and other external variables and slitting tension, pressure and other internal variables, the document control management is performed to form an operation guidance document. Minimize the influence of subjective factors, reduce the impact caused by insufficient individual ability or excessive dependence on experience, and continuously supplement, optimize and improve the operation guidance documents to meet the needs of system management.
