Bopp Tape Paper Core Cutting Machine

Bopp Tape Paper Core Cutting Machine

Tape slitting machine technical parameters
One: Introduction to tape slitting machine
The slitting machine mainly divides the large-rolled master roll into products of different widths and can check the quality of the product. Its main features are as follows:
1. Unwinding photoelectric correction, high precision; divided into two files: manual and automatic
2, there can be two ways of winding: surface winding and center winding;
3. The unwinding tension adopts automatic tension;
4, round knife cutting, reliable quality, easy to adjust;
5, using the surface center winding, the winding quality is even and stable;

6, the fixed length automatically stops, the length automatically counts the meter;

7, has a trimming device, the edge material is discharged by the fan;
8. Particularly suitable for slitting of narrow strips (insulating materials, mica tapes, films, etc.)

Reasons, countermeasures and effects of BOPP film slitting quality ---

 

six. Burr
Most of the reason for the burrs is that the cutting knife is too blunt, and replacing the cutter can solve the problem. Different types of films have different degrees of wear and tear on the cutters. The thicker the thickness, the greater the wear on the cutters, and the wear of the cutters due to the titanium dioxide and other materials. It is fast, so it is necessary to adjust the blade cutting position or replace the blade according to different cutting objects in time to avoid the appearance of raw products. Due to the high cost of cutting the raw edge product (retrocuting processing cost and edge material loss), it is much higher than the value of the scrapping blade. Therefore, preventive measures should be taken, and the replacement cycle of the blade should be budgeted. Adjust or replace the blade before the problem occurs. Blades reduce losses.

ten. Color circle
The color circle is caused by a certain degree of contamination inside or outside the film, which causes the quality of the color circle on the end face of the film roll after slitting and winding. Membrane surface pollution sources come from two aspects. One is the film-forming process. The color circles generated in the front part of the film, such as raw materials, feeding systems, extrusion systems, and die flow channels, generally cause pollution to the inside of the film (core layer). Some color-circle products can clearly observe a large amount of fish-eye impurities in the film. The color circles generated in the film-forming stage and the slitting process mainly cause pollution to the outside (surface) of the film, but whether it is internal or external pollution, It is impossible to remove the impurities from the contaminated film and restore the original appearance. The product with serious color circle has low transparency, the film color is different from the normal product, and it can not be used at all. It can only be reduced to other external treatments, while the products with slight color circles are It has little effect on the transparency of the product and does not affect the use effect of the single film. However, due to the inconspicuous appearance of the color circle product, the “selling phase” is poor, which has a great influence on the image of the German brand. It is not suitable for direct delivery. Secondary processing. If the color circle is caused by external dust pollution factors, the dust will be adsorbed on the surface of the film, resulting in poor quality of heat sealing and poor laser compression.
