Abstract

The invention relates to the field of disposable hygiene products, in particular to a forming process for large girdles of baby diapers. The forming process comprises the following steps: step one, paper diaper bodies are manufactured on line, a plurality of rubber bands are output and are compounded with a non-woven fabric material after undergoing sizing, and then the non-woven fabric is folded to cover the rubber bands; step two, spot breaking is performed on part of the rubber bands by using a spot breaking mechanism, and spot breaking parts are located in the middle and at the two ends of each rubber band; step three, dotted line cutting is conducted on the continuous large girdles through a dotted line cutter mechanism, wherein the width of the part which is not cut off ranges from 0.25mm-0.5mm, and it is guaranteed that the rubber bands are cut off; and step four, the continuous large girdles are transferred through a transposition transversing mechanism, snapping between every two adjacent large girdles is realized through accelerated operation of suction cups, then acceleration is conducted, and the large large girdles are compounded onto the paper diaper bodies after rotating by 90 degrees. The forming process solves the technical problem that an existing production equipment process cannot form the large girdles with the 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...
