Bopp Tape Slitter Rewinder

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 ---

eleven. Width deviation is too larg

Each user orders the film according to the shrinkage rate of the processed object and the film to accurately calculate the film width, try to get the lowest value to reduce the production cost. Therefore, the slit film width is too small, it is very easy to cause users. The processing width is not enough, and the film width is too large, which causes waste on the user's materials. In both cases, the user's complaint or even compensation may be caused. In actual operation, although the film width has a certain tolerance, the film width should be adjusted as much as possible on the standard width of the production construction sheet.
     Excessive deviation of film width is generally caused by human factors. Therefore, in the process of slitting, we need to detect the film width in the first time after conversion, transfer of specifications, transfer, equipment cleaning, equipment maintenance, adjustment of the tool holder, and replacement of the blade. The problem of preventing excessive deviation of the film width occurs.

twelve. Interface quality problem (poor interface quality, interface identifier does not match)

3. Interface length and interface rate requirements
Since the interface products will inevitably generate certain scraps before and after the interface, and the quality of the interface products cannot reach 100% of the quality level of the interfaceless products, increasing the loss of use, therefore, the film manufacturers and users are The number of interfaces of the volume product and the interface ratio of each batch of products are specified, so that the interface products are controlled within a certain range.
