Description
Technical field
The utility model is specifically related to a kind of apertured nonwoven cloth hot wind molding machine.
Background technology
At present, apertured nonwoven cloth is due to the characteristic of soft pro-skin, so being widely used in physiological napkin or paper diaper
It waits in hygienic absorbent products, it is dry-ness to improve its, it will usually perforate or embossing are carried out on apertured nonwoven cloth, both accelerates body
The infiltration rate of liquid enables to body fluid to pass rapidly through surface layer and reaches absorbed layer, and when reducing use and the contact surface of human body
Product.
Existing molding machine is generally using one group of intermeshing porcupine roller or convex roller and recessed roller, CN200410028483.2
Record is known clearly a kind of boring device, and first, which squeezes module surface, has a multiple row pecker, second squeeze module have it is corresponding
Groove, the pin operationally heated opens fiber exclusion, and the fibers melt at perforating needle edge is shaped under the action of heat, makes
It obtains and membranization region is formed on the inner surface of perforate, so as to form perforate, and pass is kept using membranization region, this method lacks
Falling into is, the membranization region that fibers melt is formed although on the inner surface of perforate, when with skin contact, can still produce
Raw granular sensation influences the flexibility of non-woven fabrics.
In addition, for device in itself there is also certain defect, porcupine roller or convex roller are typically by way of engraving or turnning and milling
It is process, the porcupine roller of formation or convex roller are an entirety, in use if there is a safety pin or protrusion are damaged, then not
It can be repaired and replace, so as to form blind hole defect in production, it is necessary to which the porcupine roller or convex roller more renewed causes great wave
Take.If perforate or embossed pattern slightly change simultaneously, it is also necessary to re-work new porcupine roller or convex roller, old porcupine roller or
Convex roller cannot be utilized, production cost increase.

Description.
Embodiment 1
As shown in Fig. 1 to 5, a kind of apertured nonwoven cloth hot wind molding machine, including a hot-air oven 1 and a cylinder roller 2,
Intermediate ring-type arrow represents the rotation direction of cylinder roller 2, and external straight arrow represents the direction of hot wind in hot-air oven 1.
Cylinder roller 2, side wall to carry non-woven fabrics fiber net and with several mesh 21 and several Shaped inserts 22,
Above-mentioned 21 array of several mesh sets and the air penetrability of its side wall surface is made to reach 6500L/m2/ s, each Shaped insert 22 include
One has forming part 222 on the lower connecting portion 221 and one of bayonet arrangement, and Shaped insert 22 is arranged at circle by lower connecting portion 221
The side wall of net drum 2, upper forming part 222 include a bulge-structure 2220, and the shape of the bulge-structure 2220 is pyramid-shaped (rib
The crest line of cone and the angle of vertical direction are 10~20 degree), it is highly 3mm, the centre-to-centre spacing between adjacent two Shaped insert 22 is
5mm, the floor space of upper forming part 222 is 3mm2；
Cylinder roller 2, which rotates, to be set in hot-air oven 1, the hot wind from hot-air oven 1 being made to pass through above-mentioned several mesh
21 lead in cylinder roller 2 and 1 inner recirculation flow of hot-air oven so that be carried on cylinder roller 2 and be formed plug-in unit 22 into
The non-woven fabrics fiber net sizing of type.It is specific as follows：
Non-woven fabrics 3 is manufactured using the utility model, by 1.5dtex two-component PE/PET fibers by opening bag, fibre-opening unit
Be combed into web, subsequently into the utility model, due to the utility model 2 surface forming plug-in unit 22 of cylinder roller on into
The bulge-structure 2220 in type portion 222 can penetrate web so that fiber is centered around the week of the upper forming part 222 of Shaped insert 22
It encloses, while the mesh 21 on 2 surface of cylinder roller can be penetrated in the hot wind of hot-air oven 1 so that fiber sheath melts, between fiber
It is adhered to one another, networking is consolidated, so as to form the non-woven fabrics 3 with 31 structure of perforate.
The top of perforate 31 on non-woven fabrics 3 is located at the upper surface of non-woven fabrics 3, and the bottom of perforate 31 is located at non-woven fabrics 3
Lower surface is simultaneously concordant with lower surface, since the shape of the bulge-structure 2220 of the upper forming part 222 of Shaped insert 22 is pyramid-shaped,
So that the cross-sectional area at the top of perforate 31 is more than the cross-sectional area of bottom, infundibulate perforate 31 is formed, not only improves infiltration, again
Effectively prevent returning the generation oozed, and pyramid-shaped structure is conducive under easily being removed from Shaped insert 22 after fiber net forming
Come.Since the shaping of non-woven fabrics 3 and perforate are carried out at the same time, fiber is only distributed across around perforate 31 and is mutually bonded by fiber
Networking, therefore be not in that fiber is cut off the stiff broken end to be formed or melting forms the region of fiber compression or membranization region,
The flexibility of non-woven fabrics 3 will not be destroyed because of perforate, is reduced because of granular sensation caused by perforate.And in use
The presence of perforate 31 considerably increases the speed oozed under body fluid, effectively reduces the risk of side leakage and leakage.Shaped insert simultaneously
22 lower connecting portion 221 is to be arranged on by buckle structure on cylinder roller 2, be broken in the event of a small number of Shaped inserts 22,
Bending is when cannot repair or Shaped insert 22 is distributed when being slightly adjusted, as long as replacing or Shaped insert 22 that adjustment is a small number of
It achieves that, greatly reduces repair or the replacement cost of mold, also save repair or make the time of new molding die.
