Description

Technical Field

[0001] The utility model relates to the technical field of packaging, and particularly refers to a portable heat shrink film packaging machine. Background Art

[0002] A heat shrink film packaging machine, also known as a heat shrink packaging machine (also called a shrink packaging machine, heat shrink machine, shrink machine or film wrapping machine, etc.), mainly functions to wrap a product with a heat shrink film and then heat it so that the film shrinks to tightly wrap the product. Heat shrink machines are widely used in the single, collective or combined packaging of products such as food, beverages, medicine, daily chemicals, hardware, wood products, cultural supplies, printed products, plastic products, glass products, electronic components, etc.

[0003] Existing heat shrink film packaging machines include a lifting device for a hot cutting knife. The lifting device is drivingly connected to lifting connecting rods on both sides. The upper ends of the connecting rods are connected to a "mouth"-shaped hot cutting knife holder. The hot cutting knife holder is additionally connected to a cutting cylinder to complete the cutting of the heat shrink film for packaging. However, lifting connecting rods and their supporting back plates are provided on both sides of the packaging machine, greatly increasing the weight of the packaging machine and adding a lot of costs to the production, transportation and use of the packaging machine, which needs to be improved.
