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 1

[0065] Such as Figure 6 As shown, the production system for producing the ultra-thin composite core product in this embodiment includes a plurality of pinch driving rollers, a polymer feeding device H, a composite drum device L and a coating device M. The manufacturing system of the present invention has high manufacturing precision, good product molding, and high degree of automation in the online generation process.

[0066] The pinch drive roller is arranged on the upstream or downstream side of the composite drum device L; the pinch drive roll includes a first pinch drive roll C1, a second pinch drive roll C2, a third pinch drive roll C3, the fourth pinch driving roller C4 and the fifth pinching driving roller C5, the first pinching driving roller C1, the second pinching driving roller C2, the third pinching driving roller C3, the fourth pinching driving roller The top rolls of C4 and the fifth pinch drive roll C5 are all pinch rolls, and the bottom rolls are all drive r...

Embodiment 2

[0087] Embodiment two, such as Figure 12 to Figure 13 As shown, the grooved raising device also includes a heating rod N9 arranged in the inner cavity of the drive shaft N3, the diameter of the heating rod N9 in this embodiment is compared with that of the heating rod N9 in Embodiment 1 Slightly thinner, an installation hole for installing the heating rod N9 is arranged on the wall surface of the inner cavity of the drive shaft N3. The heating rod N9 can heat the airflow in the airflow channel.

[0088] The installation and arrangement of the heating rods N9 can be properly selected according to actual needs, and are not limited to the above two arrangements. In the actual application process, one of the above two arrangements of heating rods N9 can be selected.

[0089] The slotting and fluffing 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 ultrathin composite core product, and a composite core comprises a hot-blast nonwoven, a fluffy hot-blast nonwoven, a polymer absorbent material and a cladding nonwoven which are successively laid from top to bottom. A production system for producing the ultrathin composite core product comprises a plurality of clamping driving rolls, a polymer feeding device, a composite drum device and a cladding device; the clamping driving rolls are disposed at the upstream side or downstream side of the composite drum device; the hot-blast nonwoven and the fluffy hot-blast nonwoven are gradually conveyed to the composite drum device after being clamped by a first pressing roll; a discharge port of the polymer feeding device is disposed at a product composite position on the composite drum device; the cladding nonwoven is gradually conveyed to the composite drum device; and a composite core is formed after a product composited by the composite drum device is claded by the cladding device. Compared with the prior art, the ultrathin composite core product has the advantages of good diversion diffusion performance, excellent absorption property, fast permeability speed and small reverse osmosis amount.

Description

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