Description

Technical Field

[0001] The patent of this invention relates to the technical field of sanitary napkin processing, specifically, to die-cutting equipment for non-woven fabric layers and perforated film layers used in sanitary pad processing. Background Art

[0002] Sanitary napkins are absorbent materials. Their main materials are cotton, non-woven fabrics, pulp or polymers and polymer composite paper formed by composites of the above materials. The side design is mainly used to prevent side leakage. Because it will be at a certain angle to the sanitary napkin body when used, it is more likely to rub against the groin. Therefore, sanitary napkins with sides made of soft materials are more popular among women.

[0003] Sanitary napkins are divided into three layers, namely the surface layer, the absorbent core, and the bottom layer. The adhesive backing of sanitary napkins is made of waterproof material, which can retain menstrual blood in the sanitary napkin and absorb the menstrual blood flowing out of the vagina during menstruation. However, the surface layer of traditional sanitary napkins is composed of a non-woven fabric layer and a perforated film layer. Since the outer edges of the two are not combined, it is easy to cause side leakage during use due to untimely penetration of the perforated film layer.

[0004] The invention with patent number CN215435083U discloses a non-woven fabric layer and perforated film layer die-cutting and sealing device for sanitary napkin processing. The circular convex seat is distributed on the outer surface of the interlaced glue dispensing roller to form a sanitary napkin shape; an interlaced glue dispensing needle is interlaced in the middle of the circular convex seat, and a limit ring is arranged in the middle of the interlaced glue dispensing needle. The upper end of the limit ring cooperates with the reset spring to flexibly clamp the interlaced glue dispensing needle in the reserved groove; the upper end of the interlaced glue dispensing needle is provided with a sealing seat, and the sealing seat is movably embedded in the inner wall of the glue storage tank in the middle of the interlaced glue dispensing roller; the outer side of the upper end of the interlaced glue dispensing needle is provided with an introduction groove, and the outer side of the interlaced glue dispensing needle needle head is provided with an outlet hole. It adds a puncture glue dispensing roller before the traditional sanitary napkin die-cutting, so that the non-woven fabric layer on the surface of the sanitary napkin and the edge of the perforated film layer are pressed together during the die-cutting process to prevent the sanitary napkin from leaking sideways during the downward penetration process.

[0005] The above-mentioned die-cutting and sealing equipment for non-woven fabric layer and perforated film layer for processing sanitary napkins is not suitable for processing sanitary napkins of different lengths and heights, and the glue spraying time of the woven fabric layer and the perforated film layer is short, resulting in insufficient adhesion.
