A film cutting device for a transparent film packaging machine and its use method

Abstract

The invention discloses a film cutting device for a transparent film packaging machine and a method for using the same. It is disassembled and vertically installed on the film cylinder frame of the transparent film packaging machine. The horizontal positioning assembly is movably installed on the bottom plate. The vertical shaft assembly is fixed on the horizontal positioning assembly, and the vertical shaft assembly is connected to the There is an anti-cut fixing component, and a slitting film component is connected below the anti-cutting fixing component. The slitting film component can slide vertically on the vertical shaft component. The plane is vertical, and the top of the slitting film assembly away from the vertical shaft assembly is provided with a slitting knife, and the edge of the slitting knife is close to the film roll. The invention utilizes the gravity of the slitting film module itself and the rotation of the film roll to realize automatic slitting, and the waste film after slitting is automatically rolled up and neatly left on the film roll.

Description

Technical field [0001] The present invention relates to the field of transparent membrane packaging machine, and more particularly to a transparent film packaging machine separation membrane device and its use. Background technique [0002] Transparent film packaging machine is widely used in medical, food, health products, tea, cosmetics, gifts, stationery supplies, audio-visual products, etc., all-in-one or multi-piece automatic outer packaging, etc. Dust, landscaping, etc. [0003] During the envelope of the transparent film packaging machine, it is necessary to slit excess film according to the size of the case to be packaged. The existing transparent film packaging machine is divided into the following defects: 1, the device itself requires additional power, the structure is complex, the volume is too large, improves the cost of machine, the operation is very troublesome; 2, it is difficult to cut the film in the film Accuracy, easy to generate errors, affect the use effect;...

AI Technical Summary

Problems solved by technology

The existing film cutting device of transparent film packaging machine has the following defects: 1. The device itself needs additional power, the structure is complicated, the volume is too large, the cost of the machine is increased, and the operation is very troublesome; 2. It is difficult to control the cutting of the film belt during the film cutting process. Accuracy is prone to errors and affects the use effect; 3. The waste film after cutting cannot be rolled and needs to be collected manually, or a waste film collection device should be installed separately, otherwise it will pollute the working environment, which will increase the workload and machine cost.
