Description

Technical Field

[0001] This utility model relates to the field of hygiene product manufacturing and processing equipment technology, and more specifically, it relates to a release paper cutting mechanism for nursing pads. Background Technology

[0002] In the production of disposable hygiene products, nursing pads come in various specifications, with lengths of 450mm, 600mm, 750mm, 800mm, 900mm, 1000mm, 1200mm, and 1500mm to meet the needs of different users. Nursing pads have multiple release liner sheets, which cover the adhesive backing. To use, the release liner is peeled off, exposing the adhesive and securing the pad. The number and length of release liner sheets vary for each specification. Currently, the cutting and pressing of the release liner into the pad requires manual assistance, resulting in low automation, low production efficiency, and frequent dimensional errors. Therefore, we propose a new release liner cutting mechanism for hygiene products. Utility Model Content
