Description

Fly cutter assembly and film cutting device comprising same

Technical Field

The utility model relates to a film processing field, especially a fly cutter subassembly and contain film cutting device of this subassembly.

Background

The traditional film cutting method generally has two modes, one mode is to use a chopper to perform segmented cutting on the film, and the other mode is to use a fly cutter to perform segmented cutting on the film, the cutting mode is generally determined by the width of the film, and the fly cutter is generally used for cutting the film with larger width.

However, since the flying cutter is generally disposed at a fixed angle to the film conveyance direction, the film conveyance speed needs to be adjusted to suit different film materials. The oblique angle formed on the cut film is the angle formed by the cut film under the movement of the fly cutter in the transverse direction and the movement of the film in the longitudinal conveying direction, the oblique angle is covered in a winding shaft for winding, the wrinkling phenomenon of the bottom film is caused by a larger oblique angle, and the wrinkling phenomenon of the bottom film can cause that part of the film or even longer film needs to be scrapped. Meanwhile, the blade is installed at a fixed angle, so that the cutting angle is fixed, the high-speed conveying of the film only leads to a larger bevel angle, the production cost is greatly improved by considering whether more waste films are generated under the condition of meeting the highest conveying speed of the film material and adopting the conveying speed, and the conveying speed of the film is actively reduced to avoid the larger bevel angle generated under the cutting processing of the film made of certain materials, so that the production efficiency is reduced.
