Manufacturing system and method for absorbing articles

Abstract

The invention discloses a manufacturing system and method for absorbing articles. The system is provided with a first carrying unit, a second carrying unit, a first connecting workstation, a second water-absorbent particle adding device, a third carrying unit, a second connecting workstation and a first water-absorbent particle adding device. The problem that the traditional system difficultly meets requirements of on-line manufacturing of composite cores is solved. The method comprises the following processes of primary spreading, secondary spreading, edge folding, compacting, air discharging, dotting and compounding and the like. On-line manufacturing of composite cores is realized. The manufacturing system for absorbing articles has the advantages of low manufacturing cost and good absorbing effect. The gap in the field of on-line forming of composite cores is filled, and the technical support is provided for on-line production of the composite cores. The manufacturing system is simple in structure, accurate in control and high in production efficiency.

Description

technical field [0001] The invention relates to the field of manufacturing disposable sanitary products, in particular to a manufacturing system and a manufacturing method for absorbent cores in sanitary products such as paper diapers, pull-up pants, and sanitary napkins. Background technique [0002] The absorbent core is the most important part of disposable absorbent products. The performance of disposable absorbent products is mainly determined by the absorbent core, such as water absorption, retention, diffusivity, reverse osmosis and so on. In the prior art, the absorbent core is generally designed by fluff pulp or wood pulp fibers and superabsorbent resin particles according to a certain ratio and structural distribution. At present, the common absorbent core bulk fiber molding methods mainly include the following two types: (1) ) Upper layer: fluff pulp or wood pulp fibers or a small amount of superabsorbent resin particles at the same time, middle layer: fluff pulp ...

AI Technical Summary

Problems solved by technology

[0005] However, the above-mentioned patent does not disclose the specific structure of the water-absorbing particle application device

[0006] In particular, the current production of composite cores in the industry generally adopts offline manufacturing methods, that is, the manufacturing, winding, and storage of composite cores are completed through independent special equipment. It is inevitable that the bodies will squeeze each other, resulting in a decrease in the cohesive force between the layers, thus affecting the absorption effect.

Moreover, the offline manufacturing of composite cores still has the problem of high manufacturing costs, which restrict the processing speed of the production line
