Tape Roll Rewinder Machinery

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.)

six. Burr

Another reason for the burrs is the quality of the parent roll.
First, when the mother roll product is wrinkled, the burr phenomenon is likely to occur when the film is cut to the sipe roll and the film is not effectively flattened;
Second, when the film is thick or thin for a long time, the film is prone to burr phenomenon when the film is not attached to the sipe, especially in the triangular position of the thickness. In addition, since the thinner the film, the lower the stiffness, and the higher the chance of burrs.

nine. Scratch

     In addition, sometimes scratches due to slitting are difficult to detect by the naked eye, but scratches (scratches) will attenuate the corona value of the product. According to experience, the corona value is reduced by about half in the normal cutting process. Dyne, when the corona values ??differ by more than one dyne before and after cutting, the reasons for the cutting process, such as the speed ratio of the driving roller, the quality of the sand skin, the condition of the sipe roll, etc., should be checked to eliminate the influence. .
     It is worth mentioning that there is a kind of abrasion that is caused by the slitting process, but it is mainly caused by the cutting factor. It is mainly that the mother roll is too loose, and the product of the loose part is horizontally or vertically tilted during the slitting process. While scratching the film surface, it is found that the phenomenon is to install the upper splint on the mother roll for positioning, and secondly, the cutting speed should be properly controlled, and the influence of the quality of the mother roll on the cutting quality can be improved as much as possible.
