Embodiment Construction

[0037] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0038] refer to Figure 1 to Figure 7 , the present embodiment provides a perforated adsorption process for a soft foam core of a liquid sanitary napkin, comprising the following steps:

[0039] (1) Manufacture of the absorbent core 10:

[0040] The driving device 7 drives the delivery of the polymer carrier material, and the unloading device 2 feeds the polymer material onto the polymer carrier material to form the absorbent core 10;

[0041] (2) Compression of the absorbent core 10:

[0042] The formed absorbent core 10 is clamped and conveyed between the first pressing roller and the second pressing roller of the pressing device 3, and the absorbent core 10 is pressed into a flat state;

[0043] (3) Perforation of the absorbent core 10:

[0044]The absorbent core 10 is clamped and transported between the first rotating roller 41 and the second...

Abstract

The invention relates to a perforating and adsorbing process for a soft foam core body of a liquid sanitary napkin, and a production device for the soft foam core body comprises a rack, and a blanking device, a pressing device, a perforating device, an adjusting device, a driving device and a cutting roller device which are sequentially arranged on the rack, the perforating device comprises a first rotating roller and a second rotating roller which are rotatably and correspondingly arranged on the rack, an adsorption cavity is formed in middle of the first rotating roller, one end of the first rotating roller is connected with a rotating connector, the rotating connector is connected with an adsorption device, at least one perforating area is arranged on the first rotating roller, and a plurality of cutters are arranged on the perforating area. The invention relates to the field of disposable hygienic products, the adsorption device adsorbs excess materials into the adsorption cavity and then discharges the excess materials out of the adsorption cavity, perforating efficiency is improved, quality of an absorption core body is improved, and technical problems that when an absorption core body is perforated, excess materials affect the production environment, equipment is prone to being damaged, and perforating quality of the absorption core body is affected are solved.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to a process for perforating and absorbing soft foam cores of liquid sanitary napkins. Background technique [0002] Existing absorbent cores of sanitary napkins are mainly composed of wood pulp, non-woven fabrics, toilet paper, and macromolecules. There are traditional problems such as easy deformation, limited absorption, high square gram weight, high density, softness and poor touch with the human body. Some absorbent cores are provided with a plurality of pressing holes, which not only enhance the softness of the absorbent core, but also enhance the liquid absorption rate of the absorbent core. The equipment for pressing holes usually uses two pressing rollers. However, after punching, the remaining material is separated from the absorbent core, and the remaining material remains on the equipment or the absorbent core, which not only affects the production environmen...
