Gum Tape Slitter And Rewinder

Gum Tape Slitter And Rewinder

Tape slitting machine feeding, filming and filming
1. Loading: According to the requirements of the cutting plan, according to the driving operation rules, according to the actual situation, hoist the corresponding mother roll on the aging frame, place it on the unwinding unwinding frame according to the inner and outer selection direction of the corona surface, and use the control button Clamp the steel core, leave the steel core support arm and drive.
2. Film penetration: When there is no film on the slitter, the film must be penetrated. Using the slitting machine through the membrane device and the function keys, one end of the original membrane is attached to the membrane chain eyelet, and the membrane button is activated to distribute the membrane along the slitting process to be evenly distributed on each roller.
3. Film: When there is a film on the slitter, when changing the joint, use the vacuum filming table to start the filming station to the working position, manually flatten the film on the first pulling roller of the slitting machine and start the upper vacuum pumping film. Soak the film flat on the filming table, attach the double-sided tape and cut off the excess film under the tape, flatten the film on the unwinding frame and start the lower vacuum pump to make the film flat and absorb the paper. Layer and flatten the adhesive film, the joints should be neat and wrinkle-free, then turn off the upper and lower vacuum pumps to open the filming station to the inoperative position.

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.

Eight. Indentation
There are two reasons for the cause of film roll indentation. One is caused by the winding wheel of the film forming process, and the other is caused by the cutting factor. The reasons for the cutting are:
1 Due to the poor adjustment of the angle of the puller wheel, the pressure and tension of the puller wheel are concentrated on one point of the film, and the friction of the contact point causes damage to the film surface to form an indentation.
2 The winding roller is damaged, such as scratches, etc., the degree of film roll indentation is large when the scratch is longitudinal; 3 The winding roller is contaminated, causing the surface of the pressure roller to be uneven, such as adhesive tape, impurities, etc. It will also cause the film roll to be indented and the press roll must be cleaned.
Slight indentation does not affect the use of the product, but it affects the appearance of the product, causing the customer to doubt the quality of the product; the obvious indentation not only affects the appearance of the product, but also attenuates the corona value of the film, affecting the film. Processing performance.
