Description

Technical Field

[0001] This application relates to the technical field of plastic packaging film cutting, and particularly relates to a packaging film cutting device. Background Art

[0002] Plastic films are common household items. Due to their good transparency, moisture resistance, excellent heat resistance and other advantages, plastic films are widely used in various industries. Currently, in the production process of beverage products, it is usually necessary to attach a layer of plastic packaging film on their surface. However, the size of the plastic film produced by a plastic film extruder is not the size required for product packaging. Therefore, a process needs to be set up to cut it. Existing cutting equipment usually uses aluminum knives to cut plastic films. And in order to enable the aluminum knives to cut plastic films more efficiently, heat conduction holes for placing heat conduction rods are usually opened inside the aluminum knives. The heated aluminum knives can cut plastic films better. However, during use, due to the material characteristics of the aluminum knives, directly heating and using them easily causes damage to the blades. When the blades are damaged and need to be replaced, the blades and the heating rods need to be replaced as a whole set, resulting in an increase in the use cost. Summary of the Utility Model
