Abstract

The invention discloses a film breaking device. The device comprises an air shaft, a film cutting assembly, a film pressing mechanism, a film covering rolling-up mechanism and a film covering liftingmechanism; the film covering lifting mechanism comprises a transition guide roller used for changing winding guide of a thin film, the film covering rolling-up mechanism is used for pressing the thinfilm on the air shaft to form a fixed film line before film cutting, meanwhile, the film pressing mechanism can press the thin film on the film cutting assembly to form the other fixed film line, a film cutting tool is used for cutting the thin film between the two fixed film lines, the thin film is more easily cut off, and the cut opening is more flat; the film covering rolling-up mechanism is used for evenly and completely covering the cut thin film on the air shaft, a winding shaft can conveniently carry out winding action, and the finished product quality is improved.

Description

technical field [0001] The invention relates to the field of film winding machine components, in particular to a film cutting device. Background technique [0002] PET film is a kind of packaging film with relatively comprehensive performance. Its strength and toughness are the best among all thermoplastics. The tensile strength and impact strength are much higher than ordinary films. It also has excellent heat resistance and cold resistance, so it is Widely used in printing, packaging, chemical industry and other fields. During the film rewinding process, the existing plastic film is relatively thin and has poor plasticity. After cutting, it will be attached to the film on the new reel due to gravity. However, the thickness of PET film is also thicker than ordinary films, and it has strong ductility. After the PET film is cut, it cannot be coated on the winding shaft for the next winding action, and the existing film cutting device cannot cut the PET film accurately and sm...
