Most companies use this specification for production, but it will cause problems such as uneven tension, which will cause large wrinkles on the diaper when worn on the body, and the comfort is insufficient. Utility Model Content

[0003] Therefore, the utility model provides an elastic rubber band viscose composite device for an absorbent article, which solves the problem that the elastic structure of the existing absorbent article is not comfortable enough.

[0004] In order to achieve the above object, the utility model is realized by the following technical solutions:

[0005] A device for bonding elastic bands and viscose of absorbent articles comprises a frame, on which a non-woven fabric conveying line and an elastic member conveying line are respectively provided by a plurality of guide rollers, on which a glue groove and a glue roller group for gluing, a composite pressing roller and a composite steel roller for bonding the elastic band and the non-woven fabric layer after gluing, and a cold air drying box for ensuring the bonding effect are sequentially provided along the conveying direction thereof, wherein a driving wheel for driving the non-woven fabric conveying line is mounted in the cold air drying box, and a side of the non-woven fabric conveying line that is not glued is wound around the driving wheel so that a side bonded with the elastic band is cold-dried and then outputted outward.

[0006] Preferably, the composite steel roller comprises a roller shaft, an inner roller and an outer roller fixed on the roller shaft in a sleeve structure, and a cooling water channel is arranged between the inner roller and the outer roller.

[0007] Preferably, the cooling water channels are distributed in a spiral shape.

[0008] Preferably, the cooling water channel is composed of a plurality of branch channels extending along the axial direction of the roller shaft, and the width of the branch channels gradually decreases from the input end to the output end.

[0009] Preferably, the composite pressing roller is a silicone roller.

[0010] By adopting the above technical solution, the beneficial effects of the utility model are:

[0011] The utility model is different from the traditional elastic waist structure, and a layer of waterproof cloth layer for clamping is saved in the product structure. During production, glue is applied to the surface of one side of the load-bearing non-woven fabric layer through a glue groove and a glue roller group, and then the rubber band is bonded to the side surface through a composite pressing roller and a composite steel roller and compacted, and then dried, cooled and fixed by a cold air drying box at the rear end. The non-woven fabric layer to which the rubber band is bonded is driven by a driving wheel arranged inside the cold air drying box, and is continuously transported backward after being wound around the driving wheel for one circle, thereby ensuring that the non-woven fabric layer to which the rubber band is attached has a sufficient cold air drying time and the bonding structure has stronger stability.

DETAILED DESCRIPTION

[0018] The following will describe the implementation methods of the present invention in detail in conjunction with specific embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0019] Embodiment 1

[0020] refer to Figure 2 , Figure 3, a viscose bonding device for elastic elastic band 200 of absorbent article, comprising a frame, on which a non-woven fabric conveying line a and an elastic member conveying line b are respectively provided by a plurality of guide rollers, and on the non-woven fabric conveying line a, a glue groove 11 for gluing and a glue roller group 1, a composite pressing roller 2 and a composite steel roller 3 for bonding the elastic band 200 with the non-woven fabric layer 100 after gluing, and a cold air drying box 4 for ensuring the bonding effect, wherein the composite pressing roller 2 is a silica gel roller, which has low hygroscopicity and does not adhere to the material, ensuring that the bonding structure of the elastic band 200 and the non-woven fabric layer 100 is not affected, so that the equipment can be continuously operated for a long time and the cleaning frequency is reduced;

[0021] The cold air drying box 4 is provided with a driving wheel 5 for driving the non-woven fabric conveyor line a. The non-woven fabric conveyor line a is wound around the driving wheel 5 on its un-glued side so that the side bonded with the elastic band 200 is cold-dried and then outputted. Figure 2 As shown, the model of the elastic band 200 is selected to have a diameter of 10D-200D, and the center spacing between the elastic bands 200 is 0.2-4 mm, that is, a fine-denier multiple elastic band 200 layout structure is adopted; in view of the difference from the traditional elastic waist structure, a layer of waterproof cloth layer 400 for clamping is saved in the product structure, and during production, the non-woven fabric layer 100 for carrying is glued on one side surface through the glue groove 11 and the glue roller group 1, and then the elastic band 200 is bonded to the side surface through the composite pressing roller 2 and the composite steel roller 3 and compacted, and then dried, cooled and fixed by the cold air drying box 4 at the rear end, and the non-woven fabric layer 100 after the elastic band 200 is bonded is driven by the driving wheel 5 arranged inside the cold air drying box 4, and is continuously transported backward after being wound around the driving wheel 5 for one circle, thereby ensuring that the non-woven fabric layer 100 after the elastic band 200 is attached has sufficient cold air drying time and the bonding structure is more stable. In terms of the product, the elastic structure formed by the fine denier 200 rubber band has a more uniform distribution of tension, which saves more materials than similar products, reduces production costs, and improves the fit and comfort of diapers.

[0022] Embodiment 2

[0023] refer to Figure 4 Compared with the first embodiment, the composite steel roller 3 includes a roller shaft 31, an inner roller 32 and an outer roller 33 fixed on the roller shaft 31 in a sleeve structure, and a cooling water channel 34 is arranged between the inner roller 32 and the outer roller 33. The composite steel roller 3 with the cooling water channel 34 is designed to cool the viscose when the elastic band 200 contacts the non-woven fabric layer 100, thereby avoiding the position shift between the elastic band 200 and the non-woven fabric layer 100 due to the fact that most of the viscose is not cooled and fixed during the subsequent transportation process, thereby ensuring the product yield; in terms of structure, the cooling water channel 34 is distributed in a spiral shape, and such a structure makes the cooling effect of the composite steel roller 3 more uniform.

[0024] Also refer to Figure 5 The cooling water channel 34 is composed of a plurality of branch channels extending along the axial direction of the roller shaft 31, and the width of the branch channel gradually decreases from the input end to the output end. This is another cooling structure that can be adopted, and the cooling effect that can be achieved is faster, the cooling water flows faster, and the cooling capacity is stronger.

[0025] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
