Small Adhesive Tape Slitting And Rewinding 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.

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.

eleven. Width deviation is too large
     The width of the film roll is limited by the gap of the sipe roll. The actual slit width will deviate from the width required for the order, but the deviation should be controlled within the tolerance range of ±2mm required by the national standard. The so-called width deviation Large, that is, the actual width of the film roll exceeds the requirements of internal control standards or customer standards.
     Not all products have a tolerance of ±2mm, and some customers can only take deviations from the film width, such as the Pd film of Kunshan Zhangpu, the LL film of Shanghai Zhicheng, the PL film of Beijing Amcor, etc. It is required to adjust the film width.
