Description

Technical Field

[0001] This utility model relates to the field of disposable hygiene product production equipment, and in particular to a folding device for the large ear flaps of an adult diaper. Background Technology

[0002] In the production of diapers, the folding of the large ear flaps is one of the key processes. Traditional large ear flap folding devices have a relatively simple structure and single function, resulting in many problems during production. For example, during the unwinding and feeding of the ear flap nonwoven fabric and magic hooks, the tension is difficult to control precisely, which can easily lead to material stretching, deformation, or loosening, affecting the accuracy of subsequent processing. During the folding process, the lack of effective pressure points and adjustment mechanisms results in uneven and irregular ear flap folds, failing to meet the production requirements of high-quality diapers. Moreover, in the slitting and transfer stages, problems such as ear flap misalignment and inaccurate slitting can easily occur, leading to low production efficiency and a high product defect rate.
