Preparation system of water absorbing core bodies

Abstract

The invention relates to a preparation system of water absorbing core bodies. A material delivery component of the preparation system can convey fluffy cotton to the starting end of a driving component in the driving direction, and a plurality of outlets of a material supply component for conveying the mixture of fluff pulp and hot melting fiber to the driving component are all positioned in the middle part of the driving component in the driving direction; a material charging port and a material discharging port which are used for conveying polymer water absorbing resin to the driving component are arranged in interval in the driving direction of the driving component, and the material charging port is positioned between two of the outlets; a vacuum adsorption device can adsorb the mixture of fluff pulp and hot melting fiber on the driving component, and a hot air penetration device can conduct hot air penetration treatment on stacking pieces; an ultrasonic cutting device of a slitting mechanism can conduct ultrasonic cutting on the stacking pieces after the hot air penetration treatment. The water absorbing core bodies prepared by the preparation system are not easy to layer after the water absorbing resin absorbs water, and have a good water absorbing effect; meanwhile, the production efficiency can be effectively improved, and manpower can be saved.

Description

technical field [0001] The invention relates to the production field of hygiene products, in particular to a preparation system for a water-absorbing core. Background technique [0002] Usually, diapers, sanitary napkins, etc. need to have better water absorption performance, so they generally have water absorption cores. At present, there are two main production methods for water-absorbent cores. One method is to use fluff paddles and polymer water-absorbent resin (SAP, SUPER ABSORBENT POLYMER,) to mix online. Although the cost is low, the product diffuses quickly and has multiple absorption effects. Good, but after the water-absorbent resin swells after absorbing water, the connection between the fluff pulp is poor, and it is easy to break and swell, which not only affects the comfort of use, but also affects the effective use time. In order to avoid swell, the manufacturer reduces the water-absorbent resin. However, it reduces the absorption and usage time of the product...

At present, there are two main production methods for water-absorbent cores. One method is to use fluff paddles and polymer water-absorbent resin (SAP, SUPER ABSORBENT POLYMER,) to mix online. Although the cost is low, the product diffuses quickly and has multiple absorption effects. Good, but after the water-absorbent resin swells after absorbing water, the connection between the fluff pulp is poor, and it is easy to break and swell, which not only affects the comfort of use, but also affects the effective use time. In order to avoid swell, the manufacturer reduces the water-absorbent resin. dosage, but it reduces the absorption and usage time of the product

Another way is to use fluffy non-woven fabric to fix SAP, and use hot-melt composite expanded paper (or dust-free paper, non-woven fabric, etc.) on the upper and lower sides respectively, and obtain the product after winding and cutting. The absorbent core obtained by this method Although the connectivity of the body has been improved, the connectivity is still not enough. After the polymer absorbs water and swells, the stratification is obvious. The single-point multiple water absorption is poor, and the linear expansion is slow, which is easy to cause side leakage and rear leakage.

[0003] At present, for the production of multi-layer absorbent cores, each layer is usually formed by multiple molding, and then the layers are stacked, which requires multiple productions, which not only consumes manpower, but also leads to low production efficiency.
