Bopp Sealing Tape Slitting Rewinding Machine

Bopp Sealing Tape Slitting Rewinding Machine

Preparation of slitter cutter
1. Razor slitting
1.1. The razor slitting requires the film to travel in the correct direction to the winding section.
1.2. Adjust the photoelectric tracking to bring the film to the proper position.
1.3. Tension the film and attach the blade to the razor holder.
1.4. According to the specifications required by the instruction sheet, the sliding razor holder is cut into the razor groove under the film, and the blade edge and the edge of the sipe are required to be in contact with each other.
1.5 After adjusting the depth of the cutter, lock the razor frame screws.
2. Round knife cutting
2.1. Check whether the upper and lower knives are sharp and have no gaps, and vice versa;
2.2. Determine the number of knives (N+1) according to the number of product series (N);
2.3. Install the lower knife to adjust the width of the lower knife according to the actual width of the product;
2.4 Install the upper knife correctly. The flat side of the upper knife is aligned with the side of the lower cutting edge. The upper knife is aligned with the gap between the lower knife and the septum. Press the screws on both sides to make the upper knife enter the gap depth to about 2mm. The upper knife is attached to the lower knife and fastened. Finally, the screw on the left side of the upper knife holder is adjusted so that the whole knife holder moves 1-2 mm to the right side and is fastened.

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.

It should be noted that although the quality index of the film has a tolerance upper and lower limit, such as 10m wrinkle, film width ± 2mm, end face irregularity ≤ 1 mm, etc., tolerance is the limit of product quality acceptance, but Does not mean that our products can be continuous or close to the upper and lower limits of the tolerance during the slitting process. When we find that the product is at or near the upper and lower limits of the quality tolerance, the production operation or equipment must have an abnormal situation, we must Take immediate measures to correct, eliminate the influencing factors, and ensure the continuous stability and improvement of product quality.
