Description

Technical Field

[0001] The utility model relates to the technical field of express bag processing, in particular to a winding mechanism for express bag production. Background Art

[0002] Courier bag winding usually refers to the process of winding continuously produced plastic film or non-woven fabric and other materials into rolls through specific mechanical equipment (such as a winder) during the courier bag production process.

[0003] In the existing technology, express bag rewinding usually involves installing an air inflation shaft on the rewinder, which can quickly inflate and fix the express bag, and then quickly unload the express bag after deflation, thereby improving production efficiency and applying tension to the express bag to prevent the express bag from deflecting during the rewinding process.

[0004] However, if the express bag roll needs to be installed on the air shaft, the tension generated by the air shaft due to inflation will not directly act on the express belt, and thus the tension applied by the air shaft cannot act on the express bag. Therefore, the express bag may be skewed when it is rolled up, which will not only lead to a decline in the appearance quality of the express bag and inconvenience in use, but in severe cases it will accelerate mechanical wear and even cause safety hazards.
