Reasons, countermeasures and effects of BOPP film slitting quality ---
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.
Slitting machine operation guide ---
8.1 The cutting personnel shall record the production status in the “production record of the cutting machine” and other related records, insert the product into the “product tracking card”, and fill in the corresponding content in time according to the column and frequency requirements set in the record. The disk customers fill in the theoretical weight of each product for the weight of the product label of the Xiamen Cigarette Factory (see the attached table for the theoretical weight of each product), and the content is complete, clear, true and accurate.
8.2 Records should not be filled in with a pencil. The record holder should sign the quality record and indicate the time the record was filled.
8.3 The records listed in the record (except the remarks column) should be filled in. If the corresponding content is not found or there is no item, it can be recorded by slashing. The operator should write the full name and must not only write the last name.
8.4 Record changes caused by mistakes, etc. shall not exceed three pages per page. The records shall be clearly identifiable after the change. For all kinds of quality records that are validated and validated by the product and system, the change shall be stamped with a proofreading or marked change. people.
Domestic cutting machine development status and outlets ---
three. Domestic slitting machine development direction
The development direction of domestic slitting machines should be considered from three aspects:
1. Frame structure: Whether it is a slitting or a second or third slitting, domestic slitting machine manufacturers should invest their energy and study on the frame structure, and actually design a more reasonable slitting machine to get rid of the cutting machine manufacturers. At present, the plagiarism of the slitting machine produced, the research and design of a personalized slitting machine, making the different materials in the structure more detailed, in the next round of international market competition, to provide a favorable weapon for film-making enterprises, At the same time, I also find out the blue ocean for my own company.
