Description

Technical Field

[0001] This utility model relates to the field of plastic bag winding technology, and more specifically, to a plastic bag flattening and winding device. Background Technology

[0002] Plastic bag winding refers to the process of mechanically or manually winding plastic film or plastic bags into a roll for easy storage, transportation and use. The wound plastic bags are usually cylindrical, making them easy to handle by automatic packaging machines or manual handling.

[0003] In the existing technology, during the winding process, due to the long production line of plastic bags, partial overlap is likely to occur. Once partial overlap occurs during the winding process, it can easily lead to unevenness after winding and gaps between the winding layers. Utility Model Content
