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,
Methods include:
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;

Domestic cutting machine development status and outlets ---

three. Domestic slitting machine development direction
The development direction of domestic slitting machines should be considered from three aspects:

2. Automation control part: At present, the automation level of the slitting machine produced in China is still at the middle and lower level. Although the domestic control of the original device has been widely used and the price is lower, the domestic slitter manufacturers are far away in use. It lags behind the level of developed countries, especially in the control system, and the lack of organic combination with the structure of the slitting machine and the material to be cut. At this level, most of the domestic slitting machines still stay on the thick lines. The rigor and rationality of the cutting machine control system has not been fully understood. I personally think that the domestic slitting machine manufacturers should start from the above several directions, and find out the method that meets the cutting and cutting principle of the slitting machine and can maximize the use of the functions provided by the hardware.
