In addition, there are special occasions and people under 60 years old, and adult diapers are needed.

In the process of purchasing adult diapers, water absorption, leakage resistance, comfort and fit are always main factors of consideration for consumers to purchase. In the use process of the adult diaper, some occasions need to walk back and forth, and the joint of the diaper and the groin at the time rubs repeatedly, so that certain skin discomfort is caused. In the use process of the adult diaper, some occasions need to be seated. Particularly, after urine is soaked, when the diaper is seated on the seat, the diaper soaked by the urine has poor air permeability, and can keep sitting posture on the seat for a long time, so that the diaper is easy to cause red rash of buttocks.

The leakage-proof property is focused on the existing adult diaper, for example: the adult diaper disclosed in CN201510439312.7 has the advantages that the crotch is not easy to leak liquid, and the side leakage prevention and the rear leakage prevention effects are good; the adult diaper disclosed in CN201510435987.4 is a magic buckle, is convenient to use, has good lateral seepage prevention effect and good backward seepage prevention effect. And neglecting the damage to the skin in the exercise process, the paper diaper is not suitable for the needs of medical staff walking for a long time. There are also diapers that solve the problem of eczema by frequent replacement, for example, the auxiliary pad included in the adult diaper in cn202110855547.X can be replaced after use, and the included diaper body can be selectively continued for use. But obviously, the paper diaper is not suitable for medical care, and in the scene, the medical care is generally in a bacterial environment and faces a large number of patients to be treated, and the replacement of the paper diaper can cause pollution and scrapping of protective clothing.

For this reason, an adult diaper and a production apparatus thereof are proposed to solve the problems of inguinal friction during frequent walking of a user and erythema during sitting for a long time.

In the present embodiment, as shown in fig. 11 to 21, in comparison with the third embodiment, the diaper body 10 is further provided with a ventilation unit 30; as shown in fig. 11, in a schematic plan view structure of the diaper after the attachment, a ventilation unit 30 is provided in a bottom region in the figure, and when a user sits on the diaper, the ventilation unit 30 expands to leave a partial gap in the super absorbent resin layer 13.

As shown in fig. 13 to 19, the ventilation unit 30 includes a top chassis 31, a bottom chassis 32, and an expansion assembly; the expansion assembly includes an adjuster 33, a first link 34a, a second link 34b, a guide post 35a, and a spring 35b; the bottom of the top seat 31 is fixedly connected with a guide column 35a, the top end of the guide column 35a is fixedly sleeved with an adjuster 33, the adjuster 33 is hinged with one end of a first connecting rod 34a, the other end of the first connecting rod 34a is hinged with one end of a second connecting rod 34b, and the other end of the second connecting rod 34b is fixedly connected with an expansion plate 39; the sleeve 37 is sleeved on the outer surfaces of the top seat 31 and the base 32, a channel for the second connecting rod 34b to slide through is formed in the base 32, an expansion hole 38 is formed in the surface of the sleeve 37, and the second connecting rod 34b is fixedly connected with the expansion plate 39 through the expansion hole 38; the number of first links 34a is four, and the first links 34a are distributed along the central circumferential array of the sleeve 37; the number of expansion plates 39 is 4 and is distributed along the central circumferential array of sleeves 37. A vertical cylindrical groove is formed in the central axis direction of the base 32, a spring 35b is arranged in the cylindrical groove, and a guide column 35a is arranged on the spring 35 b.

The upper and lower edges of the diaper body 10 are provided with material preparation areas 52; the superabsorbent resin loading in the preparation zone 52 is 30% of the normal loading.

As shown in fig. 14, a guide post 35a is fixedly connected to the center point of the lower part of the top seat 31, the bottom of the guide post 35a is engaged with the upper part of a spring 35b, and the spring 35b is a conical spring 35b. A cylindrical groove is formed in the base 32, and a conical spring 35b is placed in the groove. The top edge of the recess is provided with a receiving groove for receiving the regulator 33. With the downward movement of the top seat 31, the regulator 33 is driven to move downward, so that the first connecting rod 34a can be driven to move, and since one end of the first connecting rod 34b is hinged, the other end of the second connecting rod 34b is fixedly connected with the expansion plate 39. The expansion plates 39 are four in total, are respectively arranged at ninety degrees and are wrapped on the outer side of the sleeve 37. The sleeve 37 is provided with an expansion hole 38.
