Description

Technical Field

[0001] The utility model belongs to the technical field of heat shrink film packaging machines, in particular to a corner cutting mechanism of a heat shrink film packaging machine. Background Art

[0002] The heat shrink film packaging machine uses shrink film to wrap the outside of the product or package. After heating, the shrink film shrinks and wraps the product or package tightly, fully showing the appearance of the item, improving the product's sales, and increasing its beauty and value. The items packaged by the heat shrink machine can be sealed, moisture-proof, and pollution-proof, and protect the goods from external impacts. It has a certain cushioning effect, especially when packaging fragile items, it can prevent the utensil from flying when it is broken.

[0003] In the existing technology, heat shrink film packaging machines have two modes: semi-automatic and fully automatic. The cost of fully automatic equipment is high. When laminating small batches of packaging boxes, many manufacturers still use semi-automatic equipment for packaging lamination. In the semi-automatic technology, a corner cutting device is used to cut the corners of the shrink film of the packaging box during the laminating process. During the cutting process, the packaging box needs to be manually operated and the end face of the packaging box is turned over, so that the cutter device can cut the corners of different end faces. This process requires the operator to invest a large amount of work, and manual operation and flipping are prone to inaccurate alignment, which affects the cutting angle and ultimately leads to poor lamination effect.
