Detailed Description

The utility model is further described below with reference to the accompanying drawings:

a quick infiltration sanitary towel as shown in fig. 1 to 3, including wire side 1, imbibition core 2 and basement membrane 3, contain the mesh 11 that accelerates the infiltration of liquid on the wire side 1, imbibition core 2 is located between wire side 1 and basement membrane 3, is equipped with the infiltration clearance 4 that runs through imbibition core 2 and can accelerate the liquid infiltration speed on imbibition core 2.

Mesh 1 contains mesh 11, menses or urine can pass through mesh 11 and ooze 2 departments of imbibition core faster, be equipped with the infiltration clearance 4 that runs through imbibition core 2 on the imbibition core 2, the bottom surface of imbibition core 2 can reach to liquid, in-process oozes under liquid, the internal face in infiltration clearance 4, the bottom surface of imbibition core 2 and the surperficial three of imbibition core 2 absorb liquid together, accelerated liquid so by the absorptive speed of imbibition core 2, the emergence that reduces the liquid side leakage lets the sanitary towel internal surface drier and more comfortable simultaneously, increase user's comfort level.

The water seepage gaps 4 are arranged in a staggered way, and every two water seepage gaps 4 are separated by a certain distance end to end, so that the absorption area of the liquid absorption core body 2 to liquid can be enlarged, the infiltration speed of the liquid is accelerated, and the liquid is prevented from leaking from the side edge of the sanitary towel.

The longitudinal section of infiltration clearance 4 is rectangular shape, and rectangular shape is compared with the round hole and has bigger absorption area to liquid, can accelerate the speed that liquid oozes down, improves user's comfort, and simultaneously when using sanitary towel, the infiltration clearance 4 of rectangular shape enables imbibition core 2 and takes place deformation more easily, makes sanitary towel can more laminate the human body, reduces the sensation that the user felt the hard thing, increases the comfort level of using.

Be equipped with between wire side 1 and the imbibition core body 2 and be used for accelerating liquid toward the diversion layer 5 that diffuses all around and accelerate liquid infiltration, diversion layer 5 uses long fiber composite to make, and when liquid reachd diversion layer 5 back, utilizes the capillary action of long fiber, liquid can be along the fibre rapidly to diffusing all around to continue the deeper layer of infiltration sanitary towel, accelerate the infiltration speed of liquid.

The carrier film 3 is made of a breathable and liquid-impermeable material, such as PE, which ensures sufficient breathability and heat dissipation of the sanitary napkin during use, so that bacteria are not encouraged by the damp and stuffiness, thereby preventing inflammation of the lower body of the wearer, and the carrier film 3 is liquid-impermeable, thereby preventing liquid from leaking from the carrier film 3 and soiling the wearer.

The cutter for processing the absorbent core in the quick-penetration sanitary towel as shown in fig. 4 to 7 comprises an upper cutter roll 6 and a lower cutter pad roll 7, wherein the upper cutter roll 6 is provided with a first cutter edge 61, the first cutter edge 61 is used for cutting a water penetration gap 4 penetrating through the absorbent core 2 on the absorbent core 2, and the water penetration gap 4 is used for accelerating the absorption speed of the absorbent core 2 to liquid.

The first blade 61 can cut the water permeable gap 4 penetrating the absorbent core 2 on the absorbent core 2, so that the sanitary napkin can accelerate the absorption of liquid, and prevent the side leakage from dirtying the clothes of a user when the liquid amount is large.

The first cutting edges 61 are strip-shaped, the edge direction of the first cutting edges 61 and the moving direction of the upper cutter roll 6 form an acute angle, the first cutting edges 61 are arranged in a staggered mode, and every two first cutting edges 61 are spaced at a certain distance from the head to the tail.

The blade direction of the first blade 61 and the moving direction of the liquid absorption core body 2 form an acute angle, so that the first blade 61 can cut out the water seepage gap 4 on the liquid absorption core body 2 more easily, meanwhile, the first blade 61 can also play a certain protection role, the service life of the first blade 61 is longer, the first blades 61 are arranged in a staggered mode, every two first blades 61 are separated from one another by a certain distance, so that the water seepage gaps 4 cut out on the liquid absorption core body 2 are also arranged in a staggered mode, every two water seepage gaps 4 are separated from one another by a certain distance, so that the absorption area of the liquid absorption core body 2 on liquid can be increased, and the infiltration speed of the liquid is accelerated.

Go up still to be equipped with second cutting edge 62 on knife roll 6, second cutting edge 62 is used for cutting imbibition core body 2, and second cutting edge 62 can cut off imbibition core body 2, cuts into the imbibition core body 2 of a piece and conveniently places and use in the sanitary towel, is equipped with induced draft hole 71 on the lower shim roll 7, induced draft hole 71 is used for the imbibition core body 2 to let imbibition core body 2 along with lower shim roll 7's rotation and backward movement.

Before the liquid absorption core body 2 is not cut, a long strip of liquid absorption core body 2 raw material is arranged, the air suction holes 71 absorb the liquid absorption core body 2 raw material and move backwards along with the rotation of the lower knife pad roller, and then the liquid absorption core body 2 is cut into water seepage gaps 4 by the first knife edge 61 and the second knife edge 62 on the upper knife roller 6, so that the assembly line production of cutting the water seepage gaps 4 out of the liquid absorption core body 2 is realized.

The first blade 61 and the air suction hole 71 are arranged in a staggered manner, when the first blade 61 cuts the liquid absorption core body 2, a gap exists between the first blade 61 and the air suction hole 71, and the first blade 61 cannot cut the air suction hole 71.

When the periphery of the air suction hole 71 is damaged, the suction force of the air suction hole 71 on the liquid absorption core body 2 is reduced, so that the normal production is influenced, and when the first blade 61 cuts the liquid absorption core body 2, a gap is formed between the first blade 61 and the air suction hole 71, so that the first blade 61 can be prevented from cutting the periphery of the air suction hole 71, and the service life of the cutter is longer.
