Description

Technical Field

[0001] The utility model relates to the technical field of automatic packaging, in particular to a winding and strapping integrated machine applicable to PP straps and PET straps. Background Art

[0002] At present, with the continuous development of the logistics industry, goods usually need to be packed with strapping tape before transportation. With the promotion of automatic packaging technology, balers with automatic packaging function are widely used. Balers, also known as strapping machines, strapping machines or tying machines, use strapping tape to strap products or packages, and then tighten and combine the two ends through hot-melt bonding with a heating iron. The function of the baler is to reinforce the packaged items so that the items will not fall apart during transportation and storage due to loose strapping. At the same time, the items should be tied neatly and beautifully. The downward pressure baler is the most commonly used packaging equipment.

[0003] The existing downward pressure piercing arrow baler has great limitations in actual use, which leads to a narrow scope of application and poor practicality. It cannot be used for PET belts and PP belts at the same time, and it is large in size and occupies a large space. In addition, different balers may be needed for different goods. For example, solid goods and liquid goods have different rotation speeds when packaging. The existing film pulling mechanism has a constant film pulling speed and cannot meet the packaging needs of different goods. Utility Model Content
