Abstract
Description
Technical Field

[0002] Heat shrink machine, also known as shrink machine or heat shrink packaging machine, is one of the more advanced packaging equipment on the market. It uses shrink film to wrap the outside of the product or package. After heating, the shrink film is wrapped tightly around the product or package, fully displaying the appearance of the item, improving the product's sales, and increasing its beauty and value. It is widely used in packaging products such as books and playing cards.
[0003] At present, the following problems usually occur when using heat shrink machines for product packaging in the market: during the heat shrink process, multiple products will be tilted when stacked, such as playing card packaging. After the heat shrink is completed, this part of the product will cause the packaging quality to decline and the probability of defective products to increase. Similarly, for small packages such as playing cards, after the heat shrink is completed, due to the small heated surface area and uneven shrinkage, protruding sharp corners will appear on the corners. In order to solve the above problems, it is usually necessary to add manual procedures after the heat shrink is completed to complete the entire packaging step, which greatly reduces production efficiency and makes it difficult to guarantee the pass rate.
