3D cotton core manufacturing process

Abstract

The invention relates to a 3D cotton core manufacturing process, a driving mechanism drives mold cavities of a mold wheel to rotate, a plurality of mold cavities are formed in the mold wheel, and when the mold cavities sequentially rotate to a first adsorption cavity, a second adsorption cavity and a third adsorption cavity of the mold wheel, a high polymer material falls into the mold cavities of the mold wheel through a high polymer discharging mechanism; a first cotton core layer, a second cotton core layer and a third cotton core layer which are sequentially arranged up and down are formed in the mold cavities, and a cotton core is formed. The invention relates to the field of disposable sanitary articles, the height and the density of the cotton core are gradually reduced from top to bottom, the absorptivity of the cotton core is improved, materials are saved, the first cotton core layer, the second cotton core layer and the third cotton core layer which are different in width can be formed, a line shape matched with a human body curve is manufactured, a human body wears the disposable sanitary product comfortably, and the technical problems that the densities of all parts of the cotton core are the same, the cotton core absorption rate is low, the cotton core production cost is high, and the cotton core is uncomfortable to wear are solved.

Description

technical field

[0001] The invention relates to the field of disposable sanitary products, in particular to a 3D cotton core manufacturing process. Background technique

[0002] Disposable hygienic products use cotton cores to absorb liquids. The formation of cotton cores usually uses polymer cutting devices and forming die wheels to form cotton cores. The density of each part of the cotton core is consistent. When the cotton core absorbs liquid, usually a large amount of liquid First gather in the middle of the cotton wick, and then spread to the surroundings. The middle of the cotton wick absorbs a large amount of liquid, while the two sides of the cotton wick absorb a small amount of liquid. Some cotton wicks have the same thickness in each part, and often the two sides of the cotton wick absorb more liquid. Less, the absorption rate on both sides of the cotton core is low, which not only increases the weight of the cotton core, but also increases the cost of production. ...
