Fluff pulp production equipment of needle leaved wood extract used for inner pad core layer of sanitary towel

Abstract

The invention discloses fluff pulp production equipment of needle leaved wood extract used for an inner pad core layer of a sanitary towel. The equipment structurally comprises a partition rack, a needle leave purification pulp tank, a gear frame plate, a conveyor belt tank shell, a feeding chute, a base tank and a motor. The partition rack is matched with the needle leave purification pulp tank cooperates so that green juice of which chlorophyll carries cellulose and hemicellulose is separated and conveyed to a narrow-channel funnel groove; then, the hemicellulose with poor toughness is attached to the central shaft to be locally stored and removed through screening and centrifuging by a piston rod rotating stand; the brown local leaf juice flows out and is mixed in chlorophyll; upper-lower solid-liquid layering operation of lignin residues is performed through a separating funnel of a separating filter element disc to ensure that the separating filter element disc rapidly adheres tolignin to completely remove the lignin; and finally, water is injected into the terminal to enable fluff pulp to be subjected to compression with the cellulose consistency and toughness being improvedto abut against the partition rack, it is guaranteed that the fluff pulp is stirred, formed, dried and then internally plugged into a sanitary towel pad core in a sliding mode to be packaged, and itis guaranteed that cellulose is even in proportion and high in water absorption.

Description

technical field [0001] The invention relates to a fluff pulp production equipment of coniferous wood extract used for inner pad core layers of sanitary napkins, and belongs to the field of cooking and separating fibers of sanitary napkins. Background technique [0002] Sanitary napkins are commonly used monthly care products for girls, and the core pad of sanitary napkins is the main component of sanitary napkins for water absorption and pad protection, ensuring the comfort of women's use and the adequacy of water absorption. The requirements are relatively strict, and the disadvantages to be optimized in the current technology are: [0003] The leaves of coniferous wood are dense and narrow, and it is very difficult to extract cellulose, hemicellulose and lignin, which are raw materials of plant fibers. As a result, residues will remain when fluff pulp mixed with lignin has to be completely removed during pulping, and hemicellulose Partial retention is sluggish, which will...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a fluff pulp production equipment for the inner cushion core layer of the sanitary napkin using coniferous wood extracts, so as to solve the problems of dense and narrow leaves of coniferous woods and the problem of plant fiber raw materials cellulose, semi The extraction of cellulose and lignin is very difficult, resulting in residue retention when the lignin mixed with fluff pulp has to be completely removed during pulping, while the hemicellulose part remains sluggish, which will lead to insufficient removal of lignin and hemicellulose. Affecting the ratio of pure cellulose, causing the free carboxyl groups of cellulose to be affected by lignin and hemicellulose to reduce the toughness, causing shrinkage of fluff pulp after mixed processing with organic solvent and resin, and narrow fiber gaps. The water absorption rate is reduced, resulting in low efficiency of the core pad in the sanitary napkin, resulting in serious problems caused by insufficient water absorption and side leakage when using sanitary napkins
