Description
Technical Field
[0001] This utility model relates to the field of adult diaper technology, and in particular to a folding device for finished adult diapers. Background Technology
[0002] In the production process of adult diapers, the finishing folding device plays a crucial role. It is responsible not only for folding the diaper in half on both sides, but also for ensuring that the folded diaper maintains its shape and durability during the pressing and crease-forming process. However, existing finishing folding devices for adult diapers have revealed some significant problems in practical applications, especially the inability to adjust the pressing force, which has become a major bottleneck affecting product quality and production efficiency.
[0003] Adult diapers are made from a variety of materials, including but not limited to non-woven fabrics, soft cotton outer layers, absorbent cores, and breathable bottom films. These materials have different physical properties; some are softer, while others are more durable. Naturally, the required compression force varies depending on the material. However, existing edge-folding mechanisms often only provide a fixed compression force, meaning that the mechanism applies the same force regardless of the diaper material. This design can easily cause the diaper edges to deform or even tear when handling softer materials; while when handling more durable materials, insufficient compression may result in uneven diaper edges, affecting both aesthetics and wearing comfort.
[0004] A fixed clamping force can also lead to quality problems during the production process. During prolonged continuous operation, mechanical parts inevitably wear down, and the original clamping force may change, affecting the shaping of the diapers. Furthermore, different batches of diaper materials may have slight differences, such as thickness and density, requiring the folding device to adjust the clamping force in a timely manner to accommodate these variations. However, due to the lack of adjustment capabilities, existing devices cannot make these adjustments, resulting in batches of products with inconsistent quality on the production line, posing a significant challenge to subsequent quality control.
[0005] From the user's perspective, adult diapers not only need to have good absorbency and breathability, but also a comfortable wearing experience. If the folding device tightens too much, it will not only leave deep indentations on the diaper, but may also make the edges too stiff, affecting the wearer's comfort. Conversely, insufficient tightening may cause the diaper edges to loosen, affecting the integrity of its overall structure and thus the product's effectiveness. Therefore, for manufacturers who pursue high-quality products, existing folding devices are clearly insufficient to meet their requirements for meticulous product detail.
[0006] Therefore, how to provide a folding device for finished adult diapers is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
