Plastic Tape Slitting Rewinding Machine

Plastic Tape Slitting Rewinding Machine

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.

three. Irregular end faces
The end face irregularity refers to the unevenness of the end face which occurs when the film width is constant. The end face is generally in two forms: one is that the end faces are irregularly jagged, and the other is a regular wave-shaped irregularity.
1. Causes and countermeasures for uneven end faces:
1 The cutting parameters are not well adjusted. For example, if the cutting speed and the sheet/pressure are poorly matched, the sheet/pressure curve should be set according to the slitting speed;
2 abnormal vibration of the cutting device, overhaul;
3 divided and unwinding rolls are unbalanced and adjusted;
4 The parameters of the winding arms at both ends are inconsistent, and the force distribution of the winding process affects the flatness of the end face, usually the wavy end faces are not aligned and overhauled;
5 The influence of film properties, such as smoothness, etc., Ts, Pm and other models are more prominent, and the cutting parameters should be set according to different film characteristics;
6 film thickness is uneven;
7 Wrinkling during the slitting process will also cause unevenness of the end face and adjust the flattening film;
8 If the film is too static, improve the electrostatic properties of the film or check if the static eliminator of the slitter is invalid.

eleven. Width deviation is too large
     The width of the film roll is limited by the gap of the sipe roll. The actual slit width will deviate from the width required for the order, but the deviation should be controlled within the tolerance range of ±2mm required by the national standard. The so-called width deviation Large, that is, the actual width of the film roll exceeds the requirements of internal control standards or customer standards.
     Not all products have a tolerance of ±2mm, and some customers can only take deviations from the film width, such as the Pd film of Kunshan Zhangpu, the LL film of Shanghai Zhicheng, the PL film of Beijing Amcor, etc. It is required to adjust the film width.
