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.

1. Not rigorous in the manufacturing process
Tolerance control in the mechanical manufacturing process is not precise enough, and the surface is rough, especially in the matching electroplating industry, which is shoddy. There is a defect in the dynamic balance of the roller for cutting the Chinese-made equipment at one time. The lag of the related industry, the rubber coated by the roller has far less wear resistance and anti-aging than the foreign products. The bearings used seem to use well-known foreign brands, but the counterfeit and shoddy floods the domestic bearing market. Even when the real goods are purchased, the precision is far lower than the precision used by foreign slitting machines.
In the entire production process of a slitting machine, there is no guarantee of production process. At present, most of the slitting machines produced in China are completed by a number of outsourcing units, and the quality of their production is even more difficult to guarantee. In addition, the metal materials used and the heat treatment process are not rigorous enough, resulting in many problems in the use of a slitting machine. It has seriously affected the share of a slitting machine in the domestic market. The secondary and tertiary slitting machines have fewer problems than the one slitting machine, because the parts of the secondary and tertiary slitting machines are completed by the slitting machine manufacturer, and the dynamic balancing machine used is in a narrow range. It can accurately control the unbalanced grams, and the industrial difficulty coefficient of manufacturing is reduced. Its selling price is far lower than that of foreign products. Therefore, the proportion of domestically produced slitting machines in the domestic slitting machine market getting bigger.

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.
