Thermal shrinkage film cutting device for packing boxes

Abstract

The invention discloses a thermal shrinkage film cutting device for packing boxes. The device comprises a table body, an upper cutting knife, an anti-sticking structure, a lower cutting knife, an ejection structure, a fixed structure, a fixed groove, a rotating structure, support columns, grooves, a handle, a film sticking groove and a slide chute. The thermal shrinkage film cutting device for packing boxes has the beneficial effects as follows: when a fixed block drives an ejection block to rotate, the ejection blocks extrudes a fixed rod, the fixed rod is enabled to rotate in the table body,a compression spring shrinks to produce elastic force, the fixed rod pushes an ejection rod upwards during rotating, the ejection rod slides out of the lower cutting knife, the upper cutting knife and the lower cutting knife are contacted better, cutting of a thermal shrinkage film is facilitated, the fixed rod is propped against the bottom end of a slide rod during continuous rotating, the sliderod is pushed upwards, the ejection rod enters the upper cutting knife from a fixed hole, a lever is pushed to rotate in the upper cutting knife, a press rod is pushed to slide out of the upper cutting knife, the press rod is enabled to push a thermal shrinkage film which is cut between the upper cutting knife and the lower cutting knife, and the cut thermal shrinkage film is enabled to turn downwards.

Description

technical field [0001] The invention relates to a cutting device, in particular to a heat shrinkable film cutting device for a packaging box, and belongs to the technical field of heat shrinkable film cutting. Background technique [0002] Heat shrinkable film is used in the sales and transportation of various products. Its main function is to stabilize, cover and protect products. The shrinkable film must have high puncture resistance, good shrinkage and certain shrinkage stress. During the shrinking process, The film cannot produce holes. Since the shrink film is often suitable for outdoor use, UV anti-ultraviolet agents need to be added. Heat shrinkable film cutting is a device that cuts the heat shrinkable film after it is pasted on the surface of the packaging box and separates it from the unpasted heat shrinkable film. [0003] However, in the cutting process of the traditional heat shrinkable film, when the heat shrinkable film is attached to the surface of the packag...

AI Technical Summary

Problems solved by technology

[0003] However, in the cutting process of the traditional heat shrinkable film, when the heat shrinkable film is attached to the surface of the packaging box for cutting, the heat shrinkable film is easy to stick to the cutting blade, so that the heat shrinkable film attached to the packaging box is detached from the packaging box, resulting in the need to re- Paste heat shrinkable film on the packaging box, which affects work efficiency and is not conducive to the film sticking of the packaging box
