A film cutting device for heat shrinking machine for packaging

Abstract

The invention relates to the field of packaging technology, and discloses a heat shrinking machine film cutting device for packaging, which includes a packaging table and a cutting knife. The cutting knife is arranged above the packaging table, and a chute is opened inside the packaging table. The inside of the chute is slidably connected with a knife seat, and the bottom of the knife seat is fixedly connected with an upper permanent magnet block. The inside of the packaging table is provided with air passages located on the front and rear sides of the chute and communicated with the chute. A pressing mechanism is provided above the cutting knife, and the pressing mechanism is used to push the cutting knife downwards, and a rotatable upper push roller is provided below the packaging platform. The invention promotes the push rod to move outward through the centrifugal force of the rotation of the outer turntable, so that the kinetic energy of the push rod is converted into potential energy, and the energy is released instantaneously when the push rod touches the cutter, thereby increasing the cutting pressure of the push rod. It is beneficial to cut thicker films and films with insufficient tension, thereby reducing the energy consumption of the motor that drives the outer turntable to rotate.

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...
