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.

3. Lack of insight into the characteristics of different materials at the time of slitting, distinguishing between control systems and structures
Everyone knows that the physical properties of different materials are inconsistent. Some materials are smooth and firm. Some materials are very soft and soft, and the physical properties of the same material with different thicknesses are not the same. Among the slitting machines, the structure is also different, and there is a lack of changes in the control system due to its structural changes. The difference is rarely studied. In particular, the change in the difference in the control curve is even less known, and its mature control system software is still very few in China. Although some people have tried the application of a slitter control software, the chances of success are very low. Most of them are characterized by “headaches and pains.” Although our company has experienced 7-8 years of hard work, Some experience has been gained and the control system is becoming more mature, but there is still a certain gap compared with the materials covered by well-known foreign brands.

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.
