Abstract

The present invention relates to the field of disposable sanitary products, in particular to a large ring waist forming process for baby diapers, which includes the following steps: the first step, the diaper body is manufactured online, and multiple elastic bands are output and compounded with non-woven fabric materials after sizing , and then fold the non-woven fabric on the elastic; the second step is to use the point-breaking mechanism to point-break part of the elastic, and the point-breaking position is located in the middle and both ends of each elastic; The mechanism cuts the continuous large ring waist with a dotted line, and the width of the uncut part is 0.25-0.5mm, and the elastic band is guaranteed to be cut; the fourth step is to transfer the continuous large ring waist by using the indexing and transversal mechanism, and Utilize the accelerated operation of the suction cup to break the two adjacent ring waists, and then accelerate, and after the big ring waist rotates 90 degrees, it is combined with the diaper body. It solves the technical problem that the existing production equipment and technology cannot form a large ring waist with a length of 330mm.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to a large ring waist forming process for baby diapers. Background technique [0002] Baby diapers have a design structure with a large ring waist. You can refer to a large ring waist breathable diaper and its manufacturing method disclosed in Chinese patent application number: CN201910967101.9. The large ring waist breathable diapers include a bottom film layer, a cotton core and a non-woven fabric surface layer. The bottom film layer includes a PE film and non-woven fabric layers arranged on opposite sides of the PE film. Each of the The edges of the non-woven fabric layer overlap with the edges of the PE film to form an overlapping area, and the side of the non-woven fabric layer away from the overlapping area extends outward to form a breathable area, and the cotton core is arranged on the PE film. On the film, the non-woven surface layer is covered on the bottom fil...
