Absorbent core production equipment for CNC adult diaper production line

Abstract

The invention belongs to technical field of production of hygienic products. Production equipment of absorbent cores in a numerical control production line of adult paper diapers comprises an absorption mold wheel, a molding material bin and a mold unloading and conveying device, wherein a plurality of press fitting rolls are arranged on the outside of the absorption mold wheel; a high molecular water-absorbent resin feeding and mixing device is arranged on the molding material bin and comprises a high molecular water-absorbent resin feed pipe and a homogenizing and mixing pipe; and the high molecular water-absorbent resin feed pipe comprises a feed pipe body, a positive pressure inlet, a mixing outlet and a high molecular water-absorbent resin negative pressure feed inlet. The overall structural design of the production equipment realizes full mixing and shaping of high molecular water-absorbent resin with wood pulp, realizes a multilayer structure of a wood pulp layer, a mixed layer of wood pulp and high molecular water-absorbent resin and a wood pulp layer, presents gradient compactness, can effectively embody the effect of an absorbent core, and makes full use of the absorption characteristics of the raw materials and the multilayer structure.

Description

technical field [0001] The invention belongs to the technical field of hygiene product production, and in particular relates to absorbent core production equipment for a numerically controlled adult diaper production line. Background technique [0002] Hygienic products such as diapers mainly include the bottom layer, absorbent core and the surface layer in contact with the skin, and the absorbent core is the key core technology of diapers. The quality requirements for diapers are mainly reflected in the absorbent core's good absorption, dryness and non-rewetting, and side leakage prevention. And other aspects, in order to measure the quality of absorption performance of sanitary products such as diapers. [0003] The existing absorbent core molding method is mostly to use wood pulp and polymer water-absorbent resin to blend, and then absorb it on the absorbent core molding die for molding. However, the traditional molding method is to set tongue-shaped parts in the molding ...

AI Technical Summary

Problems solved by technology

In the above existing molding methods, due to the poor fluidity of the polymer water-absorbing resin and wood pulp in the molding silo, the mixing is insufficient. Loss through the molding die, resulting in a large waste of polymer water-absorbent resin particles

[0004] At the same time, the quality of the absorption performance of the absorbent core also depends on the rationality of its layer structure. The existing absorbent core is prone to uneven phenomena such as agglomeration and looseness during the molding process, resulting in poor absorption performance and liquid leakage. Phenomenon
