A 3D cotton core production process

Abstract

The invention relates to a 3D cotton core manufacturing process. A driving mechanism drives a mold cavity of a mold wheel to rotate, and a plurality of mold cavities are arranged on the mold wheel. When the mold cavity rotates to the first adsorption cavity, the second adsorption cavity and the In the third adsorption cavity, the polymer blanking mechanism drops the polymer material into the cavity of the die wheel, forming the first cotton core layer, the second cotton core layer and the third cotton core arranged up and down in sequence in the cavity. layer to form a cotton core. The invention relates to the field of disposable sanitary products. The height and density of the cotton core are gradually reduced from top to bottom, the absorption rate of the cotton core is improved, the material is saved, and a first cotton core layer and a second cotton core with different widths can be formed. layer and the third cotton core layer, making a line shape that matches the curve of the human body, making the human body comfortable to wear, solving the problem that the density of each part of the cotton core is the same, the absorption rate of the cotton core is low, the production cost of the cotton core is high, and the cotton core is uncomfortable to wear. technical issues.

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 sanitary products use cotton wick to absorb liquid. The formation of cotton wick is usually formed by polymer blanking device and molding die wheel. The density of each part of the cotton wick is the same. When the cotton wick absorbs liquid, usually a large amount of liquid is used. It first gathers in the middle of the cotton core, and then spreads around. The middle of the cotton core absorbs a large amount of liquid, while the two sides of the cotton core absorb a small amount of liquid. Some cotton cores have the same thickness in each part, and often the two sides of the cotton core absorb more liquid. 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 production cost. In the current sanitary te...
