Slitting machine instruction manual -
Second, the use of procedures;
5. After filling the nozzle, turn on the key switch power, the green light is on, pay attention to the following operations:
A. Always press the knife green button first to make the blade rotate first, and check if the rotation is smooth and there is no harsh sound.
B. Press the Drum green button again to make the drum rotate, and confirm that the small shaft in the upper right corner of the drum starts to rotate, and then start working.
C. If there is a fault and need to stop, always confirm: first press the Drum red stop button, stop for 1-2 seconds and then press the Knfe red button to stop the blade, so as to avoid the stick stick between the drum and the blade.
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;
Reasons, countermeasures and effects of BOPP film slitting quality ---
Most of the reason for the burrs is that the cutting knife is too blunt, and replacing the cutter can solve the problem. Different types of films have different degrees of wear and tear on the cutters. The thicker the thickness, the greater the wear on the cutters, and the wear of the cutters due to the titanium dioxide and other materials. It is fast, so it is necessary to adjust the blade cutting position or replace the blade according to different cutting objects in time to avoid the appearance of raw products. Due to the high cost of cutting the raw edge product (retrocuting processing cost and edge material loss), it is much higher than the value of the scrapping blade. Therefore, preventive measures should be taken, and the replacement cycle of the blade should be budgeted. Adjust or replace the blade before the problem occurs. Blades reduce losses.
