Description

Technical Field

[0001] The utility model relates to the technical field of thermoplastic packaging, in particular to a cutting material collecting and compressing device for a heat shrink packaging machine. Background Art

[0002] The heat shrink packaging machine is a device that uses shrink film to wrap items, which is used to reduce the size of the items and ensure the stability and appearance of the packaging. Its basic principle is to use electric heating to make the shrink film made of environmentally friendly materials such as PVC and PET shrink under high heat conditions. In this way, it not only helps to beautify the appearance of the product, but also ensures that the items maintain a good appearance and transportation stability for a long time. The machine has a variety of usage scenarios. It is suitable for the packaging of various items, as well as for product packaging in the pharmaceutical, food and beverage, chemical and other industries.

[0003] After sealing, the heat shrink packaging machine needs to cut off the excess clinker and collect the cut parts. Since the plastic film is thin, it can reduce the space occupied after folding. The traditional collection only requires squeezing the plastic film. When the squeezing force disappears, the plastic film returns to its original position and occupies more space again, resulting in the need to frequently remove the waste plastic film.
