Elastic waist forming machine for ring-waist diapers

Abstract

The invention discloses an elastic waistline shaping machine for a waist-surrounding paper diaper. The elastic waistline shaping machine comprises a machine frame, a rubber band output device, a non-woven cloth output device, a rubber band gluing mechanism, a non-woven cloth gluing mechanism, a half folding mechanism, a cutting-off knife rest, a steering knife rest and a non-woven glue spraying mechanism, wherein the rubber band output device is arranged on the front side face of the machine frame; the rubber band gluing mechanism implements gluing on the surface of each rubber band; the non-woven gluing mechanism implements gluing on the surface of the output non-woven cloth; the half folding mechanism folds the output non-woven cloth in half; the cutting-off knife rest is installed on the front side face of the machine frame, and implements breakpoint cutting-off on a part of the rubber bands; the steering knife rest is located on the right side of the cutting knife rest; the non-woven glue spraying mechanism is located between the cutting-off knife rest and the steering knife rest, and sprays glue onto the surface of the folded non-woven cloth. Compared with the prior art, the elastic waistline shaping machine for the waist-surrounding paper diaper provided by the invention has the advantages that, the shaped elastic waistline is of a cut point structure corresponding to the rubber band of a part which coincides with an absorption core body, so that the part, corresponding to the absorption core body, of the elastic waistline has no elastic effect; therefore after the elastic waistline is combined with a paper diaper body, the wrinkling of the absorption core body is not caused.

Description

Technical field [0001] The invention relates to the field of paper diaper production machinery, in particular to a forming machine for forming the elastic waist circumference of the diaper with ring waist. Background technique [0002] There are many varieties of traditional diapers, but most of the diapers have poor elasticity, insufficient fit when worn by babies, and easy leakage of excrement. A kind of diapers with adjustable tightness has appeared on the market, such as figure 1 As shown, the specific structure includes a diaper body and an elastic waist set at the rear end of the diaper body. The diaper body includes a non-woven fabric surface layer, a breathable bottom film completely overlapped and compounded with the non-woven fabric surface layer, and a non-woven fabric surface layer. The absorbent core between the woven fabric surface layer and the breathable bottom film, the front end of the absorbent core and the front end of the non-woven fabric surface layer have a...

Problems solved by technology

However, because the front end of the elastic waist is overlapped with the rear end of the absorbent core, the rear end of the absorbent core at the overlapping position of the elastic waist will be wrinkled due to the contraction characteristics of the elastic waist, and the wrinkle The wrinkled part is in contact with the baby's buttocks, which makes it more uncomfortable for the baby to wear
