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

nine. Scratch

     In addition, sometimes scratches due to slitting are difficult to detect by the naked eye, but scratches (scratches) will attenuate the corona value of the product. According to experience, the corona value is reduced by about half in the normal cutting process. Dyne, when the corona values ??differ by more than one dyne before and after cutting, the reasons for the cutting process, such as the speed ratio of the driving roller, the quality of the sand skin, the condition of the sipe roll, etc., should be checked to eliminate the influence. .
     It is worth mentioning that there is a kind of abrasion that is caused by the slitting process, but it is mainly caused by the cutting factor. It is mainly that the mother roll is too loose, and the product of the loose part is horizontally or vertically tilted during the slitting process. While scratching the film surface, it is found that the phenomenon is to install the upper splint on the mother roll for positioning, and secondly, the cutting speed should be properly controlled, and the influence of the quality of the mother roll on the cutting quality can be improved as much as possible.

4. Lack of independent innovation, boldly out of their own characteristics
At present, most of the domestic slitter manufacturers are counterfeit foreign products. Most of them are in the German, Japanese, and Taiwanese styles. Their structures are quite different. What's more, they are copied and copied. Not to mention serious violations of the intellectual property rights of others, there is no driving force for China's slitter manufacturing industry, which will bring China a very unfavorable factor in the next round of international market competition. Everyone knows that plagiarizing others will achieve short-term performance in the market, but in the long run, in addition to inhibiting the development of enterprises, it also has a negative impact on related industries, and also limits the film-making enterprises. Towards international competition. I personally believe that in addition to drawing on foreign advanced technology and experience, we must also focus on self-innovation, give full play to the wisdom of Chinese people, and create first-class cutting equipment at the lowest cost, so that filmmakers can make the next round. In the international competitive environment, it brings a greater competitive advantage.

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.
