Reasons, countermeasures and effects of BOPP film slitting quality ---

Seven. Sharp edge
The curling occurs at the edge of the film winding, which causes the curling. The reason is that the edge of the thick film is curled up and the edge part is lifted up; the second is that the winding is too tight, and the tension can be shortened by slitting. Speed ??to improve the resulting edge curling phenomenon; third, the cutter is too blunt, and the stretching phenomenon occurs at the slit when slitting, causing the edge of the film roll to be turned outwards after winding to cause the curling edge, and the cutting should be replaced in time. The knife can avoid the occurrence of the curling problem; the fourth is that the tool is not installed correctly, such as the blade is close to the edge of the sipe and the blade is passivated. Cutting with a round knife can improve the curling of the film roll.
In the use of the unwinding process, there will be different degrees of side-floating in the unwinding process, and it is impossible to track the alignment with the electric eye, which directly affects the use effect. Therefore, it is necessary to change the product with the curled edge.

The basic knowledge of the slitting machine and its development process --

Basic knowledge and development of slitting machine

When it comes to the efficiency of the slitter, many people think that the efficiency of the slitter is only related to the speed of the slitter. Actually, I think that the efficiency of the slitter is related to the following factors: slitting speed, finished product. Rate, non-operation time, stability, etc. Although the cutting speed is an important indicator of the working efficiency of the slitting machine, if the yield is low, not only will the work efficiency of the whole machine be low, but also the cost will increase. Similarly, if the non-operation takes a long time, such as: adjusting the machine, setting the tool, changing the tool, refueling, connecting the joint, changing the volume, processing the problem, etc., it takes a long time to improve the speed of the slitter, and it makes no sense. It is. Not to mention the stability of the slitting machine, not only will it affect the working efficiency of the slitting machine, but also affect the quality of the product, and it will cause trouble and unnecessary waste to the next process. Therefore, the efficiency of the slitter is a comprehensive concept.

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.
