Tape slitter setting control：
1. Set the slitting menu according to the type, thickness, length, width, etc. of the film arranged in the slitting plan.
2. Lift the corresponding BOPP film file from the PDF.
3. Set the winding length and width of the film of the corresponding specification.
4. Select the corresponding winding station, adjust the pressure roller arm and pressure roller, and install the paper core of the corresponding specifications.

Third, through the film：
13. After all the paper cores on both sides are glued, press “Crop 1 Clamp” and “Reel 2 Clamp” at the same time, and then press “Rewind side 1 open” and “winding side 2 open” at the same time. The position is automatically swung until the winding paper core is pressed against the upper roller, the winding main body is started, and the film is slowly wound until it is tight.

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;
