Abstract

The invention discloses a molding device for an absorber of a hygienic product. The molding device comprises a molding drum and a semi-closed molding cabin, wherein the molding drum is rotatable along an axial direction; the molding cabin is arranged above the molding drum; a fine net is arranged on the surface of the molding drum; a wood pulp inlet and a macromolecular water-absorbing material applying port are arranged above the molding cabin; two separating plates which are arranged along the axial direction are arranged in the molding cabin and are utilized to separate the molding cabin into three independent cavities, namely, a first cavity and a third cavity respectively located on two sides, and a second cavity located in the middle; the three cavities are all connected with the wood pulp inlet; and the macromolecular water-absorbing material applying port is arranged on the upper part of the second cavity. The problem that macromolecular particles leak into the molding drum from the fine net is solved by the molding device for the absorber of the hygienic product; the surface layer is free from the macromolecular particles; and the comfort level during a use process is increased.

Description

Hygienic article absorber shaped device and the absorber for preparing with this shaped device

Technical field

The present invention relates to the health care product manufacturing field of equipment, particularly a kind of diaper production line, sanltary towel for women use production line, production lines such as mattress, pet pads, and the shaped device of absorber on the medical and hygiene article production line.

Background technology

Absorber is the core body part of disposable sanitary articles such as diaper, sanitary towel, mattress, pet pads, mainly plays the juice effect that stores that absorbs.The formation of absorber is (as shown in Figure 1) shown in following sectional view: be to be formed by elongated wood pulp cellulose and granular macromolecule water absorbent material uniform mixing.Absorber moulding process on production line (as shown in Figure 2) as shown in the figure: shaped device is to be combined by the assembly drum that can produce the negative pressure effect, semi-enclosed molding storehouse, isolates with 40 purpose fine-structure meshes between assembly drum and the molding storehouse.Wood pulp cellulose gets into from inlet and send molding storehouse and the macromolecule water absorbent material uniform mixing that is applied to this district, on fine-structure mesh, has been formed absorber by the negative-pressure adsorption of assembly drum at last.Because action of negative pressure, tiny polymeric particles can leak in the assembly drum from 40 purpose fine-structure meshes, causes waste, in addition, is attached to the polymeric particles of absorber surface, and its harder physical characteristic can influence the comfort sense when using.

Summary of the invention

In order to overcome above-mentioned defective, the invention provides a kind of hygienic article absorber shaped device, the absorber with this shaped device preparation is provided simultaneously.

The present invention realizes through following technical scheme:

A kind of hygienic article absorber shaped device; Comprise the assembly drum of axial rotation and be arranged at semi-enclosed molding storehouse of assembly drum top; Said assembly drum surface is a fine-structure mesh; Top, molding storehouse is provided with the wood pulp inlet and macromolecule water absorbent material applies mouth, has two dividing plates that axially are provided with that the molding storehouse is divided into three independently cavitys in the said molding storehouse, is respectively first cavity, the 3rd cavity that is positioned at both sides and is positioned at intermediary second cavity; Said three cavitys all are communicated with the wood pulp inlet, and said macromolecule water absorbent material applies mouth and is arranged at the second cavity top.

The further improvement project of the present invention is that the upper end of first cavity, second cavity and the 3rd cavity is communicated with the wood pulp inlet.

The further improvement project of the present invention is that the wood pulp inlet of second cavity enters the mouth greater than the wood pulp of first cavity, the 3rd cavity respectively.

The further improvement project of the present invention is that first cavity, the 3rd cavity are symmetricly set in the second cavity both sides.

With the hygienic article absorber of above-mentioned shaped device preparation, said hygienic article absorber is made up of surface layer and sandwich layer, and said surface layer is coated on the sandwich layer two sides.

The further improvement project of the present invention is, said surface layer is a wood pulp fiber layer, and said sandwich layer is wood pulp cellulose and granular macromolecule water absorbent material mixture.

The invention has the beneficial effects as follows:

The moulding storehouse is divided into three independently cavitys with dividing plate; Macromolecule water absorbent material applies at second cavity; All do not apply macromolecule water absorbent material in first cavity and the 3rd cavity,, formed the sandwich layer of wood pulp cellulose and the mixed uniformly absorber of granular macromolecule water absorbent material in the absorber at last by the rotation of assembly drum; Both side surface coats the not wood pulp cellulose superficial layer of pbz polymer absorbent material thinly; Solved polymeric particles and can from fine-structure mesh, leak into the problem in the assembly drum, the what is more important superficial layer is the pbz polymer particle not, has improved the comfort when using.

The specific embodiment

In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.

Fig. 3 has shown the embodiment of a kind of hygienic article absorber of the present invention shaped device: the present invention includes theassembly drum 1 of axial rotation and be arranged atsemi-enclosed molding storehouse 2 of assembly drum top, saidassembly drum 1 surface is a fine-structure mesh 3.

Still as shown in Figure 3; There are two dividing plates that axially are provided with that the molding storehouse is divided into three independently cavitys in the saidmolding storehouse 2; Be respectivelyfirst cavity 21, the3rd cavity 23 that is positioned at both sides and be positioned at intermediary second cavity, 22, thefirst cavitys 21, the3rd cavity 23 is symmetricly set in second cavity, 22 both sides.Said three cavitys all are communicated withwood pulp inlet 4, and said macromolecule water absorbent material appliesmouth 5 and is arranged at second cavity, 22 upper positions.The upper end offirst cavity 21,second cavity 22 and the3rd cavity 23 is communicated with wood pulp inlet 4.The wood pulp ofsecond cavity 22inlet 4 is respectively greater than thewood pulp inlet 4 offirst cavity 21, the3rd cavity 23.

With the hygienic article absorber of former preparation, said hygienic article absorber is made up ofsurface layer 6 and sandwich layer 7, and saidsurface layer 6 is coated on sandwich layer 7 two sides.

Saidsurface layer 6 is a wood pulp fiber layer, and said sandwich layer 7 is wood pulp cellulose and granular macromolecule water absorbent material mixture.

Shown in arrow among the figure; Rotation throughassembly drum 1; At first the wood pulp cellulose infirst cavity 21 is adsorbed to fine-structure mesh 3 surfaces (formation surface layer); Then get into second cavity, 22 absorption wood pulp cellulose and granular macromolecule water absorbent material mixture (formation sandwich layer), get into the3rd cavity 23 absorption wood pulp celluloses (formation surface layer) at last, the absorber of formation is as shown in Figure 4; The mixed uniformly absorber sandwich layer 7 of wood pulp cellulose and granular macromolecule water absorbent material, both side surface coat the not wood pulpcellulose surface layer 6 of pbz polymer absorbent material thinly.
