A kind of fluff pulp production equipment of coniferous wood extract for inner pad core layer of sanitary napkin

Abstract

The invention discloses a fluff pulp production equipment of coniferous wood extract used in the inner pad core layer of sanitary napkins, the structure of which comprises: a barrier frame, a coniferous pulp purification tank, a gear frame plate, a conveyor belt tank shell, and a feeding chute , base slot, and motor. The present invention realizes the cooperation of the barrier rack and the coniferous pulp purification tank, so that the green juice of chlorophyll with cellulose and hemicellulose is precipitated to the narrow channel funnel tank, and then rotated by the piston rod. The hemicellulose with poor toughness attached to the central axis is partially stored and removed by the frame sieve and centrifuged, and the partial leaf juice with brown color is mixed with the chlorophyll before, and the upper and lower sides of the lignin residue are also formed through the liquid separation filter plate separation funnel The solid-liquid layering operation ensures that the liquid-separating filter disc is quickly bonded and the lignin is completely removed. Finally, the terminal is filled with water to compress the fluff pulp to increase the cellulose consistency and toughness = against the barrier frame to ensure the agitation and molding of the fluff pulp. The dry-processed inner slip is inserted into the pad core of the sanitary napkin and packaged to ensure that the cellulose ratio is uniform and the water absorption is strong.

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
