Abstract
Description
Technical Field
[0001] The utility model relates to product packaging equipment, in particular to a heat shrink packaging machine. Background Art
[0002] Many products need to be wrapped and protected by heat shrinking after manufacturing and quality inspection. The principle is to put the heat shrink film on the outside of the product, and then use hot air to blow the heat shrink film. When the heat shrink film shrinks, the product can be tightly wrapped, which can not only play a protective role, but also prevent moisture and dirt. The existing packaging method is generally to blow hot air on the heat shrink film with a handheld hot air gun. This operation method is not only inefficient, but also easily causes holes in the heat shrink film due to local overheating, which cannot meet the process requirements. Utility Model Content
