Tape slitting machine principle：
1. The paper slitting machine shall carry out the fixed length slitting processing of the whole roll or the whole raw material, such as plastic packaging materials, packaging carton, steel plate, film, leather, wood chip, etc., and the fixed length slitting control shall be used.
2. The slitting length can be set continuously. If there is an error in the actual slitting length, it is easy to calibrate by setting parameters.
3. The slitting control of the paper slitter is divided into static and dynamic slitting: it stops accurately when the set length arrives, then static slitting processing, restarts after slitting; when the set length arrives, it does not stop. The slitting signal is dynamically slitted during the material movement process.
Slitting machine operating procedures -
Third, through the film：
9. Press “Device Jog” again, and the film on both sides will be flattened until the slitting film appears on the winding side 2, and the film is cut with a knife.
10. Manually pull the slit film on the winding side 1 and the winding side 2, bond the film to the corresponding paper core, and tighten the film and stick the flat film to the paper core (note the side 1 and side 2 films). Wearing different methods).
11. Manually adjust the leading edge probe into position.
12. Set the winding length and winding diameter on the operation screen (see the preset length and diameter method for details)
Causes, countermeasures and effects on the quality of BOPP film slitting quality ---
two. Wrinkle (wrinkle, vertical wrinkle, cross wrinkle, line wrinkle)
Through many years, the BOPP industry has carried out a series of intensive and meticulous work on solving the problem of wrinkling. From the two aspects of process parameter screening and equipment adjustment and transformation, we have found a set of effective solutions and received very good results. effect,
1 The wrinkles near the core of the paper can not be stretched, which is largely related to the contact roller pressure of the slitter. It has been proved that when the contact roller pressure is increased, the wrinkles increase, and when the pressure is reduced, the wrinkles are reduced, and the air inside the film roll is reduced. The amount is increased, so that the gap between the membranes is increased to reduce friction, which is beneficial to reduce wrinkles;
2 When the winding pressure is small, the wrinkle is less, but the small pressure will cause the film roll to run off. Therefore, it is very important to set the pressure curve reasonably. When starting, set a small pressure, when it is easy to wrinkle. After a length of time has passed, the pressure should be increased rapidly to avoid the occurrence of deviation;
3 In the improvement of wrinkle, the control of winding tension should be considered. If only the winding pressure is considered, the initial pressure setting value will be very small. In case of special circumstances, the deceleration will cause deviation due to small pressure. Defects, so the tension curve setting is also very important, and the winding pressure and tension must be matched properly.
4 The pressure at the core of the paper cannot be reduced indefinitely. If it is too small, the inside of the film roll will be too loose, and the end face will appear star-shaped, causing the film to wrinkle. Therefore, it should be adjusted to the film roll when setting the pressure curve. The end face has neither a star shape and minimizes wrinkles;
