Elastic waistline shaping machine for waist-surrounding paper diaper

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 diaper production machinery, in particular to a molding machine for compound molding the elastic waist of ring-waist diapers. Background technique [0002] There are many varieties of traditional diapers, but most diapers have poor elasticity, are not suitable for babies when worn, and excrement is easy to leak. There is a kind of adjustable tightness diapers on the market, such as figure 1 As shown, its specific structure includes a diaper body and an elastic waist arranged at the rear end of the diaper body. The absorbent core between the woven surface layer and the air-permeable bottom film has a first distance between the front end of the absorbent core and the front end of the non-woven surface, and the rear end of the absorbent core and the non-woven surface There is a second distance between the rear ends of the elastic waist, the elastic waist is within the second distance, and the front end of the elasti...

AI Technical Summary

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
