Production line of absorbable core

Abstract

The invention relates to the technical field of production of absorbable sanitary supplies, and in particular, relates to a production line of an absorbable core, wherein the production line includesa conveying line, and a first roller, a flattening mechanism, a fluff pulp injection mechanism, a cutting mechanism and a blanking mechanism which are arranged on the conveying line in turn in the direction of process production, and also includes a narrow paper supply device arranged above the blanking mechanism; the narrow paper supply device is provided with a second roller and a folding mechanism; the folding mechanism is used for folding wide paper into narrow paper. The folding mechanism folds the wide paper into the narrow paper, so that an upper layer and a lower layer of the absorption core adopt the same material but have different thicknesses, and the versatility of the material is increased. The wide paper is folded into U shape and then fluff pulp is injected, and the injection position of the fluff pulp is ensured to be accurate, so that the fluff pulp corresponds to the position of the narrow paper.

Description

technical field [0001] The invention relates to the technical field of production of absorbent sanitary products, in particular to a production line of absorbent cores. Background technique [0002] Sanitary napkin is a kind of absorbent material, the main material is cotton, non-woven fabric, pulp or high molecular polymer composite paper formed by the composite of the above materials. Sanitary napkin is divided into three layers, which are surface Layer, absorbent core, bottom layer, absorbent core layer is generally designed by water-absorbent fibers and polymer absorbent resin particles according to a certain proportion and structural distribution, and it is usually formed by stacking fibers in a three-layer structure distribution, that is, the upper layer: water-absorbent fiber (or contain a small amount of polymer absorbent resin at the same time), the middle layer: water-absorbent fiber / polymer absorbent resin particles are evenly mixed, the bottom layer: water-absorb...
