By adopting the technical scheme, the utility model has the beneficial effects that:

1. this scheme has realized the reduction to the air humidity of forming device body department through the setting of sealed cowling body, ventilation pipe body, air intake, air exit, draught fan, dehydrating unit, wherein, dehydrating unit can be a body, inside packing have the drier can, perhaps other current conventional dehumidification structure. In addition, be provided with dust collector on dehydrating unit's the front end or the rear end, dust collector's setting can cooperate dehumidification structure to realize the removal of dust to can effectively improve the production smoothness nature of forming device body department better.

2. According to the scheme, the upper material input mechanism, the first application mechanism, the composite non-woven fabric input mechanism, the second application mechanism and the lower non-woven fabric input mechanism are arranged around the adsorption mechanism through the adsorption mechanism and according to the assembly line, so that a more effective application process flow is formed, the stability of macromolecule broadcasting on the composite non-woven fabric is better, and the working efficiency and the stability of the high-polymer non-woven fabric are higher, particularly in a high-speed running state. After the first macromolecule is broadcast, the adsorption area adsorbs the first macromolecule on the upper layer non-woven fabric, after the composite non-woven fabric is covered, the second macromolecule is broadcast, and then negative pressure adsorption is carried out again, so that the second macromolecule is adsorbed in the composite non-woven fabric.

In order to achieve the best stability, the projection of the first inclined roller and the second inclined roller in the width direction is limited to have a radial overlapping part, the area of the radial overlapping part is not more than 10% of the maximum cross-sectional area of the first inclined roller and not less than 2% of the maximum cross-sectional area of the first inclined roller, unnecessary deformation of the composite non-woven fabric can be effectively prevented, the stretching in the width direction is achieved under the condition that the basic form of the composite non-woven fabric is unchanged, and the stretching stability is better. The projection of the first inclined roller and the second inclined roller in the conveying direction is provided with an axial overlapping part, the length of the axial overlapping part is not more than 30% of the axial length of the first inclined roller and not less than 10% of the axial length of the first inclined roller, and still the stretching stability is better.

5. The oscillating device is arranged, so that polymer particles can better enter into the upper fiber layer and the lower fiber layer of the composite non-woven fabric. In practice, a plurality of oscillation devices can be adopted, and the formed absorption core can be subjected to repeated overturning oscillation or multiple angle oscillation, so that better uniformity is realized. The oscillating device can be of various structures, and an upper oscillating plate and a lower oscillating plate are only one structure, and also can be of oscillating rollers or other conventional structures. Moreover, the oscillating device may be not only a mechanism of the upper oscillating plate and the lower oscillating plate, but also other structures in the prior art.

6. The arrangement of different adsorption forces is mainly based on that the thickness of the adsorption materials is inconsistent after the adsorption materials are laminated, and the required adsorption force is correspondingly adjusted according to the thickness. In addition, the positive pressure area can also be a negative pressure area, the positive pressure area can realize that polymer particles blow into the composite non-woven fabric, the negative pressure can realize stable conveying of the composite non-woven fabric, and the improvement of the polymer particles in the area entering the composite non-woven fabric can be performed after the polymer particles are output.
