Thermal shrinkage machine film cutting device for packaging

Abstract

The invention relates to the technical field of packaging, and discloses a thermal shrinkage machine film cutting device for packaging. The device comprises a packaging table and a cutter, wherein thecutter is arranged above the packaging table, a sliding groove is formed in the packaging table, a cutter holder is slidably connected in the sliding groove, an upper permanent magnet block is fixedly connected to the bottom of the cutter holder, air channels located on the front side and the rear side of the sliding groove and communicated with the sliding groove are formed in the packaging table, a downward pressing mechanism is arranged above the cutter, the downward pressing mechanism is used for pushing the cutter downwards, and a rotatable upward-pushing rotating roller is arranged below the packaging table. According to the device, a push rod is promoted to move outwards through centrifugal force of rotation of an outer rotary disc, so that kinetic energy of the push rod is converted into potential energy, energy is released instantly when the push rod makes contact with the cutter, the purpose of increasing the cutting pressure of the push rod is achieved, and cutting of thickfilms and films with insufficient tension is facilitated; and therefore, the energy consumption of a motor for driving the outer rotary disc to rotate can be reduced.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a film cutting device of a heat shrinking machine for packaging. Background technique [0002] Shrinking machine, also known as shrinking machine and heat shrinking packaging machine, is one of the more advanced packaging methods in the current market. Wrap the product or package with shrink film, heat the shrink film to wrap the product or package tightly, fully display the appearance of the item, improve the product's exhibition and sales, and increase the beauty and value. During packaging, the film is wound on the film frame, and a part of the film is wrapped on the product after the product passes through the film frame. The heat shrinking machine is equipped with a sealing knife mechanism, which is used to cut and seal the heat shrinkable film wrapped around the product. The existing sealing knife adopts a cam mechanism to press down the blade to cut off the heat-shrinka...
