A line cutting device for polyethylene plastic film

Abstract

The invention belongs to the technical field of film production, and particularly relates to a polyethylene plastic film wire cutting device. The polyethylene plastic film wire cutting device comprises a rack, a raw material roller, a first transmission roller, a second transmission roller, division pieces and a winding roller, and further comprises a fixed unit and a cutting unit. Through the arrangement of a control unit, a mold plate can be replaced with a corresponding one according to different cut opening shapes, the cut opening shape of a film is controlled through the mold plate, the mold plate is low in price and easy to manufacture, film cutting is completed on the same equipment, and therefore the film cutting efficiency is improved; meanwhile, a film is cut during rotating of acutting wire, on one hand, the film cutting cost is reduced, meanwhile, the situation that the cutting speed is influenced by wire cutting along with film thickness changing is avoided, and thereforethe film cutting efficiency is improved; and on the other hand, consumption of the cutting wire is low, the machining precision is high, and therefore the film cutting effect is improved.

Description

Technical field [0001] The invention belongs to the technical field of film production, and specifically is a polyethylene plastic film wire cutting device. Background technique [0002] Slitting machine is a kind of mechanical equipment that cuts wide-width film, mica tape or paper into multiple narrow-width materials. It is often used in papermaking machinery, wire and cable mica tape and printing and packaging machinery. The slitting machine is mainly used for: mica tape, paper, insulating material and film slitting, especially suitable for slitting narrow tape (insulating material, mica tape, film, etc.); the cutting principle of traditional film slitting machine is two The cutting roller is squeezed and cut by the cutter on the roller, but sometimes it is necessary to cut out cutting edges of different shapes, such as: straight, wavy, zigzag; and the existing slitting machine cannot change the cutting For the shape of the edge, part of the slitting machine needs to replace ...

AI Technical Summary

Problems solved by technology

However, the control of the cutting edge shape of the film in this technical solution is inconvenient, which affects the cutting efficiency of the film. At the same time, laser cutting makes the gap between the films too small, and the films are easy to mix, thus affecting the separate storage efficiency of the later films; limit
