Bopp Adhesive Packing Tape Slitting Machine

Inspection and preparation before the cutting machine is turned on
4.1.1. Confirm that the main power supply voltage is 380V.
4.1.2. Turn on each power switch and check if the electricity and gas supply are normal.
4.1.3. Before starting the machine, you must confirm that the surface of each guide roller is smooth and free of burr dust, debris, etc. When cleaning the machine, use alcohol or water to soft cloth.
Wipe, can not be wiped with other solvents, remove the impurities around the equipment and production, to ensure normal production;
4.1.4. Obtain all kinds of accessories and tools such as slitting products and tapes in strict accordance with the production instruction sheet and the process card requirements.
4.1.4.1. Receive the composite film specified on the production instruction sheet, check whether the composite film tracking card is complete, and describe the previous quality problem is it clear.
4.1.4.2. Confirm the cut specifications, roll direction, batch number, material structure, winding diameter or meter number according to the production order. 4.1.5. Carefully check the equipment to confirm that each rewinding mechanism, EPC device, and tension control system are normal, and confirm static electricity.
Whether the elimination is normal or not;
4.1.6. The unwinding material is ready, and then the film is routed in the correct way;
4.1.7. Prepare the winding paper core according to the slitting specifications and place it in the corresponding position of the winding reel.

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.

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.
