Bopp Stationery Tape Jumbo Rolls Slitting 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.)

three. Irregular end faces
The end face irregularity refers to the unevenness of the end face which occurs when the film width is constant. The end face is generally in two forms: one is that the end faces are irregularly jagged, and the other is a regular wave-shaped irregularity.
1. Causes and countermeasures for uneven end faces:
1 The cutting parameters are not well adjusted. For example, if the cutting speed and the sheet/pressure are poorly matched, the sheet/pressure curve should be set according to the slitting speed;
2 abnormal vibration of the cutting device, overhaul;
3 divided and unwinding rolls are unbalanced and adjusted;
4 The parameters of the winding arms at both ends are inconsistent, and the force distribution of the winding process affects the flatness of the end face, usually the wavy end faces are not aligned and overhauled;
5 The influence of film properties, such as smoothness, etc., Ts, Pm and other models are more prominent, and the cutting parameters should be set according to different film characteristics;
6 film thickness is uneven;
7 Wrinkling during the slitting process will also cause unevenness of the end face and adjust the flattening film;
8 If the film is too static, improve the electrostatic properties of the film or check if the static eliminator of the slitter is invalid.

nine. Scratch
      Whether the slitting and scratching can be compared and determined by the film surface before and after the slitting, there are various reasons for the scratching of the membrane surface, and the analysis should be based on the appearance of the scratch, such as short-line scratching. The difference of the speed ratio of each drive roller exceeds the process setting requirement, and it needs to be carefully tested and adjusted. If the film surface scratch occurs continuously, the film on the slitter should be inspected for whether it touches the fixed object or cuts each. Whether the roller adheres to dirt such as fine sand grains scratches the film surface.
Scratch is the appearance quality problem of the film, which directly affects the quality appearance of the deep-processed product. Therefore, it is not allowed to exist in the film quality control standard. The slitting process finds that the scratching problem must be carefully checked and quickly eliminated. Since the scratch on the film surface is an irreversible appearance quality problem, it is not allowed to operate the disease when the film surface is scratched, so as to avoid the continuous occurrence of the problem.
