Description

Technical Field

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

[0002] Plastic bags are bags made of plastic as the main raw material. They are items in people's daily lives and are often used to hold other items. They are widely used because of their low cost, extremely light weight, large capacity, and easy storage. In the process of plastic bag production, the plastic bags need to be rolled up for easy storage.

[0003] When the existing plastic bag winding device is in use, its height position is usually fixed. When the plastic bag is gradually thickened while being wound on the winding roller, the outer plastic bag may rub against the bottom of the winding device, causing wear on the plastic bag. The amount of plastic bags that can be wound on the winding roller at one time is limited, affecting the winding efficiency. In addition, when the sizes of some plastic bags are inconsistent, deviations may occur when they are wound on the winding roller, resulting in uneven wound plastic bags. In order to address the deficiencies of the prior art, we propose a winding device for plastic bag production. Utility Model Content
