Description

Technical Field

[0001] The present application relates to the technical field of composite film production, and in particular to a composite film production cutting mechanism. Background Art

[0002] Composite film refers to a multi-layered film formed by combining various plastics with paper, metal or other materials through lamination, extrusion cladding, co-extrusion and other process technologies to form a base material. Composite film is generally composed of base material, lamination adhesive, barrier material, heat sealing material, printing and protective layer coating, etc. Composite film needs to be processed by cutting device before production.

[0003] At present, most cutting mechanisms use cutting blades to cut composite films, and the cutting blades are always exposed to the outside. When the cutting mechanism is not needed or the composite film needs to be pulled under the cutting blade, the staff is more likely to accidentally touch the cutting blade, thereby causing unnecessary injuries and reducing the practicality of the cutting mechanism.
