Description
TECHNICAL FIELD
[0001] The present application relates to the field of sanitary product equipment, in particular to a wing sanitary napkin cotton core forming device. BACKGROUND
[0002] The wing sanitary napkin is a paper sanitary product used by women during menstruation, and is one of adult care products. The cotton core is an important main component of the wing sanitary napkin, so the forming of the cotton core determines the comfort of the wing sanitary napkin, that is, the experience of the product.
[0003] In the past structure, the high molecular water-absorbing material is fully mixed with the cotton core. Since the high molecular material is distributed everywhere in the cotton core, when the high molecular material absorbs water, it will form a barrier particle on the surface layer. The barrier particle not only affects the experience during use, but also the particle may pierce the bottom film, causing the product to break, so that the sanitary napkin cannot achieve the effect of fully locking water. Therefore, a wing sanitary napkin cotton core production forming device adjusts the position of the high molecular water-absorbing material in the cotton core during production, so that it is gathered in the middle of the cotton core, thereby avoiding the problems of the current wing sanitary napkin.
