Problems solved by technology

The surface layer of the traditional composite core uses dust-free paper. The dust-free paper has good water absorption and good water retention performance, but it is not good in diversion and diffusion performance and comfort. Therefore, in the selection of the surface material of the composite core also needs to be improved

Embodiment 2

[0087] Example two, as Figure 12 to Figure 13 As shown, the slotting and raising device further includes a heating rod N9 arranged in the inner cavity of the driving shaft N3. In this embodiment, the diameter of the heating rod N9 is compared with that of the heating rod N9 in the first embodiment. Slightly thinner, a mounting hole for mounting the heating rod N9 is also arranged on the inner cavity wall of the drive shaft N3. The heating rod N9 can heat the airflow in the airflow channel.

[0088] The installation and layout of the heating rod N9 can be appropriately selected according to actual needs, and is not limited to the two layouts described above. In the actual application process, one of the above two layout methods of the heating rod N9 can be selected.

[0089] The slotting and raising device further includes a gas introduction block N5 installed at the end of the ventilation roller N7, and the gas introduction block N5 is communicated with the air duct N6.

Abstract

The invention discloses an ultra-thin composite core product. The composite core includes hot air non-woven fabrics, fluffy hot air non-woven fabrics, polymer water-absorbing materials and coated non-woven fabrics arranged in sequence from top to bottom. A production system for producing ultra-thin composite core products, including a plurality of pinching driving rollers, polymer feeding devices, composite drum devices and coating devices; the pinching driving rollers are arranged on the upstream side or downstream side of the composite drum device; hot air The non-woven fabric and the fluffy hot-air non-woven fabric are gradually conveyed to the compound drum device after being pinched by the first pressure roller; the discharge port of the polymer feeding device is set at the product compound position on the compound drum device; the coating The non-woven fabric is gradually conveyed into the compound drum device; the product after being compounded by the compound drum device is then wrapped by the coating device to form a composite core. Compared with the prior art, the invention has the advantages of good diversion and diffusion performance, good absorption performance, fast infiltration speed, small amount of reverse osmosis and the like.

Description

technical field [0001] The invention belongs to the technical field of sanitary product manufacturing, and in particular relates to an ultra-thin composite core product and a manufacturing system thereof. Background technique [0002] As a new type of absorbent core for disposable sanitary products, the composite core is usually composed of clean paper, non-woven fabric and polymer water-absorbing material. The order from top to bottom is clean paper-polymer water-absorbing material-no Woven / fluffy hot air non-woven fabric-polymer water-absorbing material-dust-free paper, made by bonding each layer of material with hot melt adhesive. The polymer water-absorbing material is usually a polymer water-absorbing resin (SAP), which can absorb hundreds or even thousands of times of its own weight in liquid, and has a strong water-retaining capacity. Therefore, a certain amount of polymer water-absorbing material will be applied to the core to ensure the water absorption of the sa...
