Embodiment Construction

[0043] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0044] refer to Figure 1 to Figure 10 , the present embodiment provides a method for forming an ultra-thin absorbent core, comprising the following steps:

[0045] (1) Manufacture of the upper absorbent core layer 1: the first unloading device 41 cuts the polymer material onto the first polymer carrier to form the upper absorbent core layer 1, and the upper absorbent core layer 1 passes through the first pressing roller mechanism 5 On the upper surface of the upper absorbent core layer 1, five wave-shaped first flow guide grooves 11 are formed, and five wave-shaped second flow guide grooves 12 are formed on the bottom of the upper absorbent core layer 1. The first flow guide grooves 11 and the second flow guide grooves Diversion grooves 12 are arranged alternately, refer to Figure 8 , Figure 8 The five wavy solid lines are the first diversion...

Abstract

The invention relates to a method for forming an ultra-thin absorbent core. The formed absorbent core includes an upper absorbent core layer, a middle absorbent core layer and a lower absorbent core layer stacked in sequence. The middle absorbent core layer is wavy, and the middle absorbent core layer is wavy. The top and bottom ends of the upper absorbent core layer are fixed on the upper absorbent core layer and the lower absorbent core layer by point-breaking spray glue; the middle absorbent core layer is provided with a plurality of small holes, and the two sides of the lower absorbent core layer are folded on the top of the upper absorbent core layer for fixing. Form the folded portion. The invention relates to the field of disposable sanitary products. When liquid enters the absorbent core, the upper absorbent core layer and the lower absorbent core layer can move with each other to form a buffer space, so that the middle absorbent core layer forms a wave shape during production, which improves the production efficiency. The ability to buffer and absorb liquid inside the absorbent core prevents liquid from leaking out, and solves the technical problems that the absorbent core has poor diversion effect, poor absorption capacity, and easily causes liquid to flow out.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to a method for forming an ultra-thin absorbent core. Background technique [0002] When the absorbent core of disposable sanitary products absorbs liquid, the middle part often absorbs more liquid, the two sides of the absorbent core absorb less liquid, the area utilization rate of the absorbent core is small, the absorption core has poor drainage effect, and the absorption capacity is poor. Enhance the absorption capacity of the middle part of the absorbent core. Generally, the absorbent core is produced thicker. However, when a large amount of liquid enters the disposable sanitary product instantly, the absorbent core is difficult to absorb a large amount of liquid in a short time, which may cause the liquid to flow out, and the thicker Absorbent cores not only have high production costs, but also take up a large space after packaging, and the packaging and transportat...
