Description

A slitting machine for multi-layer tape processing

technical field

The utility model relates to the technical field of slitting machines, in particular to a slitting machine for processing multi-layer adhesive tapes.

Background technique

The tape slitting machine is a machine that can cut the semi-finished tape with a large width into several narrow tapes. The semi-finished tape with a large width is pulled out by the rotation of the roller shaft. The tape slitting machine is fixed with a knife holder shaft. A number of knives are arranged on the frame shaft, and the knives are fixed or slid on the knife holder, and the distance between two adjacent knives determines the width of the cut tape.

In the existing tape slitting machine, the distance between the cutter and the cutting roller is fixed when the tape is slit. If the pressure between the cutter and the cutting roller is too large, the cutter is easy to wear, and if the distance between the two is too small, the cutter is easy to wear. The cutting effect is poor, so it is difficult to adjust, and the cutting effect cannot be guaranteed. In addition, most of the existing tool rests are manually operated when pressing the rollers, which is inconvenient to use. Therefore, there is a need for a slitting machine for multi-layer tape processing that is easy to use and has a good cutting effect.
