Fully Automatic Self Adhesive Bopp Jumbo Rolls Slitting Machine Manufacture

Slitting machine operating procedures -

Third, through the film:
1. The cutter exits to the stop position. (The split knife switch is in the off position)
2. Press the “Pinch with chain” button and the hook and loop on the chain will run to the feeding position.
3. Press “Release Brake” until the indicator light is on, and the unwinder brake is released.
4. Pull one end of the film manually, pull the film along the running route to the film-piercing mechanism, and fix the film to the shackle of the chain.

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

(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.

Reasons, countermeasures and effects of BOPP film slitting quality ---

Fives. Multilateral

2. The causes and countermeasures of multilateralism:
(1) The mother roll is seriously deviated, wrinkled or uneven in thickness. When the film runs to the sipe roll, it does not stick to the roller and appears multilateral. It is necessary to improve the quality of film production.
(2) Due to the looseness of the parent roll, the floating roller in the slitting process fails to compensate for the slack in the mother roll in time to cause multilateral occurrence. At this time, it is necessary to accelerate to cope with the problem.
(2) The film roll is not effectively adjusted for the bending roll or the high and low roll or the pull wheel, and the flatness of the film during the slitting process must be improved by effective adjustment;
(3) The blade material does not meet the requirements for use, and the texture is too soft or the friction is deformed by heat. Replace the qualified blade;
(4) Poor cutting control, such as too fast slitting speed, slitting speed and poor sheet/pressure setting. Reasonable adjustment.
(5) The process of slitting due to the loss of sand skin can also cause wrinkles and a multilateral phenomenon.
(6) If the unwinding tension is too small, it will also cause multilateral phenomena.
