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

Eight. Indentation
There are two reasons for the cause of film roll indentation. One is caused by the winding wheel of the film forming process, and the other is caused by the cutting factor. The reasons for the cutting are:
1 Due to the poor adjustment of the angle of the puller wheel, the pressure and tension of the puller wheel are concentrated on one point of the film, and the friction of the contact point causes damage to the film surface to form an indentation.
2 The winding roller is damaged, such as scratches, etc., the degree of film roll indentation is large when the scratch is longitudinal; 3 The winding roller is contaminated, causing the surface of the pressure roller to be uneven, such as adhesive tape, impurities, etc. It will also cause the film roll to be indented and the press roll must be cleaned.
Slight indentation does not affect the use of the product, but it affects the appearance of the product, causing the customer to doubt the quality of the product; the obvious indentation not only affects the appearance of the product, but also attenuates the corona value of the film, affecting the film. Processing performance.

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:

3. Manufacturing: This is a common problem faced by China's manufacturing industry. Everyone knows that any mechanical equipment, besides being reasonable in design, requires precision in manufacturing, and Chinese manufacturing is lacking in this respect. The manufacturing process is also a weak link. In addition to some general-purpose machine tools, there are some special equipments for manufacturing slitting machines, such as dynamic balancing machines, water cutting machines, etc., due to the manufacturing precision requirements of the slitting machine. High, therefore, some equipment needs to use CNC machine tools to process parts, especially the need to popularize the machining center, so that the processing precision of the equipment that produces the slitting machine can be fundamentally guaranteed.
