Bopp Printed Tape Slitting Rewinding Machine

Bopp Printed Tape Slitting Rewinding 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.

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.

six. Burr
Most of the reason for the burrs is that the cutting knife is too blunt, and replacing the cutter can solve the problem. Different types of films have different degrees of wear and tear on the cutters. The thicker the thickness, the greater the wear on the cutters, and the wear of the cutters due to the titanium dioxide and other materials. It is fast, so it is necessary to adjust the blade cutting position or replace the blade according to different cutting objects in time to avoid the appearance of raw products. Due to the high cost of cutting the raw edge product (retrocuting processing cost and edge material loss), it is much higher than the value of the scrapping blade. Therefore, preventive measures should be taken, and the replacement cycle of the blade should be budgeted. Adjust or replace the blade before the problem occurs. Blades reduce losses.
