Description

Technical Field

[0001] The utility model relates to the technical field of PE film production equipment, in particular to a wear-resistant PE film trimming mechanism. Background Art

[0002] Film is a thin and soft transparent sheet. In actual production, the film can be made into different colors for use. It is mainly made of plastic, adhesive, rubber or other materials. In real life, it is widely used. However, the current PE film trimming device usually places the film on a cutting table for cutting. Since the film is a very light transparent sheet, it will flutter with the blowing of the air. If this happens during actual cutting, it will affect the cutting accuracy and reduce the beauty of the film cutting edge, which is not conducive to practical use. In addition, the existing PE film trimming device usually performs a single pressing down cutting on the film with a fixed edge. Although this can improve the efficiency of the unit cutting area of ​​the film to a certain extent, it will cause entanglement to the rest of the film, so that the thickness of some parts of the film is inconsistent, which in turn affects the subsequent use quality of the film.

[0003] A PE film trimming device with publication number CN213197705U includes a trimming machine, a fixed support and a fixed guide rail.

The lower end of the cutting frame is evenly distributed with cutting blades, and the cutting blades are rollingly connected to the cutting frame through screws. The lower end of the trimming machine is fixedly connected to a connecting frame. The PE film trimming device can avoid the film from fluttering with the blowing of the air during actual cutting through structural improvements, and can ensure that the film can be cut in a completely stationary state, thereby ensuring cutting accuracy and not affecting the aesthetics of the cutting edge. It is highly practical and suitable for promotion and use.
