Description

Technical Field

[0001] The utility model belongs to the technical field of shrink film production equipment, in particular to a shrink film continuous winding device. Background Art

[0002] Shrink film, a film material with remarkable shrinking properties, plays a vital role in the modern packaging industry. Made from polymer plastic, this film shrinks tightly onto the object it covers through heat, providing excellent packaging for goods. However, a critical step in the shrink film production process is effectively winding the finished film onto a winding drum for subsequent storage, transportation, and use.

[0003] In existing technologies, shrink film winding primarily relies on the winding mechanism within the rewinding device. However, conventional shrink film rewinding devices are often equipped with only one rewinding mechanism. Once the rewinding drum within this rewinding mechanism completes its winding task, the machine must be shut down for drum replacement. This process is not only time-consuming and significantly impacts production efficiency, but also increases production costs and labor input. In modern industrial production, which strives for efficient and continuous production, long periods of downtime are undoubtedly unacceptable. This is particularly true in the packaging industry, where production efficiency and cost control requirements are particularly stringent.

[0004] Therefore, it is very necessary to invent a continuous shrink film winding device. Utility Model Content
