Production assembly line of paper diapers

Abstract

The invention relates to an assembly line for producing paper diapers. The production assembly line of the paper diapers comprises a rack, a core body forming mechanism, a stereoscopic guard forming system, a rear elastic waistline forming system and a front waist patch forming system, wherein the core body forming mechanism, the stereoscopic guard forming system, the rear elastic waistline forming system and the front waist patch forming system are arranged on the rack. The core body forming mechanism comprises a first conveying device, a second conveying device, a bottom film retractor, an SAP recovery device and a hang-upside air scoop. The stereoscopic guard forming system comprises a rear retaining wall non-woven fabric forming mechanism, a leakage-proof side wing forming mechanism and an air draft feeding device. The front waist patch forming system comprises a front waist patch retractor, a fourth glue gun, an air draft feeder, a third cutter device and an eccentric pressing wheel which are sequentially arranged. The production assembly line of the paper diapers has the advantages that the production cost of the paper diapers is reduced, and the production efficiency and the yield of the paper diapers are high.

Description

technical field [0001] The invention relates to an assembly line for producing diapers. Background technique [0002] At present, all the production of diapers adopts automatic assembly line operation, and the composite fixing of surface layer, bottom film, absorbent core, rear elastic waist, three-dimensional protection, front waist sticker and magic buckle is realized on the automatic assembly line. The function of the rear elastic waist is to improve the comfort of the diaper and prevent urine from leaking from the rear side. Most of the existing back elastic waists are made of integral rectangular strip-like elastic sheets. During production, the strip-shaped elastic sheet is first cut to size by a cutter device, stretched and glued between the impermeable outer layer and the water-permeable inner layer. The front waist sticker is fixed on the non-water-permeable outer layer, and the diaper is worn on the human body by bonding the magic buckle and the front waist stick...

Problems solved by technology

The distance between the conveyor belts between the two processes is about 5cm. The bottom film used in the bottom film coating process enters the conveyor belt from the gap of the conveyor belt. When the core body after cutting is conveyed between the conveyor belts, the core body The SAP, that is, the polymer water-absorbent resin, will fall from the cut on the conveyor belt, or the SAP will fall from the transmission gap between the conveyor belts, resulting in waste of SAP. On the other hand, due to the glue spray on the bottom film , SAP adheres to the bottom film after falling, and it is easy to cause SAP to pierce the bottom film after being compacted by the pressure roller
