A kind of film production method

Abstract

The invention belongs to the technical field of film production, in particular to a film production method. The method adopts a linear cutting device; and the linear cutting device comprises a frame,a raw material roller, a first transmission roller, a second transmission roller, an interface piece and a winding roller, and further comprises a fixing unit and a cutting unit. Through arrangement of a control unit, corresponding templates are replaced according to different incision shapes; the templates control the incision shapes of films; the templates are low in cost and easily manufactured; the film cutting is finished on one equipment to improve the film cutting efficiency; meanwhile, the films are cut through rotation of a cutting line; on the one hand, the film cutting cost is reduced, and meanwhile, the influence on the cutting speed of linear cutting by the thickness change of the films is not generated, so that the film cutting efficiency is improved; and on the other hand, the loss of the cutting line is low, and the machining precision is high, so that the film cutting effect is improved.

Description

technical field [0001] The invention belongs to the technical field of film production, in particular to a film production method. Background technique [0002] A film is a thin, flexible, transparent sheet made of plastic, adhesive, rubber, or other material. The direct use of film produced is easy to cause waste of resources. Therefore, cutting of the film is required. [0003] 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-band insulating materials, mica tape, film, etc.; the cutting principle of the traditional film slitting machine is two cutting rollers Laminating extrusion, slitting is carried out through the cutter on the roller, but som...

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
