Description

Technical Field

[0001] This utility model relates to the technical field of hygiene product manufacturing equipment, specifically a processing device for the core of disposable hygiene products, capable of high-speed positioning and quantitative application onto the core. This machine can produce 4-layer / 5-layer cores. The machine's speed can reach over 300 meters per minute. Background Technology

[0002] Common disposable hygiene products include diapers, which have a core layer that absorbs moisture. The stability of the core layer's quality determines the product's effectiveness.

[0003] Traditional processing equipment, when applying polymers to the bottom non-woven fabric (dust-free paper) during processing, generally achieves high-speed positioning and quantitative uniformity, but cannot perform intermittent control of the main unit line. This results in hygiene products with mediocre cost control, and the polymer application process is also inefficient (the speed cannot exceed 200 meters / minute), which significantly limits its future development. Utility Model Content

[0004] This invention provides a processing device for the core of disposable hygiene products, which overcomes the shortcomings described in the background art.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A processing device for the core of a disposable hygiene product includes an adsorption mold wheel, a first conveying mechanism for conveying a bottom nonwoven fabric (dust-free paper), a first adhesive spraying mechanism for spraying adhesive onto the nonwoven fabric (dust-free paper), a first feeding mechanism for conveying a first layer of polymer onto the bottom nonwoven fabric (dust-free paper), a second conveying mechanism for conveying fluffy cotton, a second adhesive spraying mechanism for spraying adhesive onto the fluffy cotton, a second feeding mechanism for coating a second layer of polymer onto the surface of the fluffy cotton, a dust-free paper feeding mechanism for conveying the dust-free paper, a dust-free paper adhesive spraying mechanism, and a composite pressure roller. Specifically, the second composite pressure roller has an adsorption chamber on its adsorption mold wheel. The grid on the mold wheel can be customized. A first adhesive spraying mechanism sprays adhesive onto the bottom non-woven fabric (dust-free paper) to form an adhesive layer of polymer. The adsorption chamber efficiently adsorbs the polymer and feeds it onto the adhesive layer. Fluffy cotton is then sprayed with adhesive by the second adhesive spraying mechanism and superimposed on the aforementioned polymer-formed core structure. A second feeding mechanism superimposes another layer of polymer onto the fluffy cotton. A dust-free paper adhesive spraying mechanism sprays adhesive onto the dust-free paper, and the second composite pressure roller composites the dust-free paper with the aforementioned core product. When the bottom layer is non-woven fabric, the first adhesive spraying mechanism sprays adhesive onto the bottom non-woven fabric; when the bottom layer is dust-free paper, the first adhesive spraying mechanism sprays adhesive onto the bottom dust-free paper. The bottom layer of the core in disposable hygiene products is commonly made of non-woven fabric or dust-free paper. Of course, other alternatives can also be selected as the bottom layer. The key is to spray adhesive onto the bottom layer through a first adhesive spraying mechanism. The adhesive spraying action is not affected by the material of the bottom layer. The processing equipment in this utility model completes the processing of the core in disposable hygiene products through the cooperation of multiple mechanisms.

[0007] This invention employs a negative pressure adsorption method to efficiently transfer polymers, allowing them to effectively penetrate the fluffy cotton core and improve absorbency. By modifying the adsorption mesh design of the mold wheel, different forms of intermittent control can be achieved, and the amount of polymer applied at different locations can be freely set, thus realizing a customized core structure. It also allows for synchronized control with the diaper's main unit, significantly reducing diaper costs; high-speed operation is also possible, maintaining synchronous online operation with the main unit.

[0008] A preferred technical solution: The front end of the second feeding mechanism is also equipped with a first composite pressure roller to roll the product.

[0009] The front end refers to the core of disposable hygiene products being rolled by the first composite pressure roller before being processed by the second feeding mechanism.

[0010] A preferred technical solution: A composite transmission mechanism for composite and conveying is also provided at the rear end of the first composite pressure roller.

[0011] The core of the disposable hygiene product, which is composite-molded here, consists of a bottom non-woven fabric, a first layer of polymer on the bottom non-woven fabric and fluffy cotton, a second layer of polymer on the fluffy cotton, and a dust-free paper. It is then rolled and conveyed again by a composite conveyor mechanism, which can use a common conveyor belt. The rear end refers to the process where the core of the disposable hygiene product is first processed by a second composite pressure roller, and then by the composite conveyor mechanism.

[0012] A preferred technical solution: The rear end of the composite transmission mechanism is also equipped with an edge-sealing glue spraying mechanism and an edge-sealing mechanism. The edge-sealing glue spraying mechanism sprays glue onto the edges, and the edge-sealing mechanism performs edge-sealing treatment on the product.

[0013] A preferred technical solution: The back end of the edge-binding mechanism is also equipped with a finished product transmission mechanism.

[0014] A preferred technical solution: The first feeding mechanism and the second feeding mechanism include a storage bin, a roller, and a feeding bin. The storage bin is equipped with a rotatable roller. The bottom of the storage bin is an open opening that is connected to the feeding bin.

[0015] The first feeding mechanism has the same structure as the second feeding mechanism. It stores polymers in a storage bin and uses a motor to drive the rollers to rotate, so that the polymers are slowly transferred to the open opening at the bottom of the storage bin. Finally, they enter the feeding bin and cooperate with the adsorption chamber on the adsorption mold wheel to adsorb and feed the polymers.

[0016] A preferred technical solution: The feeding hopper has a feed inlet through the side wall, the feeding hopper is connected to the storage hopper through the feed inlet, and the bottom of the feeding hopper is connected to the adsorption mold wheel.

[0017] A preferred technical solution: A pressure relief port is installed through the top of the feeding hopper to avoid excessive negative pressure inside the feeding hopper, so that the polymer can fall evenly and stably onto the corresponding position of the bottom nonwoven fabric.

[0018] A preferred technical solution involves setting up multiple adsorption chambers, which are divided and coordinated into different areas. The grid design on the mold wheel, combined with the multiple adsorption chambers, allows for control of the airflow in each chamber. Different suction forces enable intermittent control of the polymer feed rate.

[0019] A preferred technical solution: three adsorption chambers are provided, namely: a first adsorption chamber, a second adsorption chamber, and a third adsorption chamber. The first adsorption chamber cooperates with the first feeding mechanism, the second adsorption chamber cooperates with the second conveying mechanism, and the third adsorption chamber cooperates with the second feeding mechanism.

[0020] By adopting the above technical solution, the beneficial effects of this utility model are:

[0021] 1. The various structures in this utility model work together to efficiently produce and output the core products for disposable hygiene products. The processing speed is fast, reaching a high speed of over 300 meters per minute. It can achieve quantitative and phase discontinuous control, and the product quality is stable.

[0022] 2. This utility model adopts a grid design in the adsorption mold wheel and different adsorption chambers in conjunction with the first and second feeding mechanisms. It uses negative pressure to efficiently transfer polymers, so that the polymers can fall into the corresponding positions at high speed, uniformly, quantitatively, and intermittently and stably, ensuring the stability of product structure and quality.

The adhesive mechanism J3, the second composite pressure roller Y2, and the adsorption mold wheel 1 are equipped with an adsorption chamber X1. The first adhesive spraying mechanism J1 sprays adhesive onto the bottom non-woven fabric (dust-free paper) to form an adhesive layer of polymer. The adsorption chamber X1 efficiently adsorbs the polymer and feeds it onto the adhesive layer. Fluffy cotton is sprayed with adhesive by the second adhesive spraying mechanism J2 and superimposed on the aforementioned polymer-formed core structure. The second feeding mechanism G2 superimposes another layer of polymer onto the fluffy cotton. The dust-free paper adhesive spraying mechanism J3 sprays adhesive onto the dust-free paper, and the second composite pressure roller Y2 composites the dust-free paper with the aforementioned core product. When the fluffy cotton is conveyed by the second conveying mechanism L2, a fluffy cotton conveying mechanism C1 can be installed at its rear end to assist in stabilizing the fluffy cotton feeding.

[0031] Furthermore, the front end of the second feeding mechanism G2 is also equipped with a first composite pressure roller Y1 to roll the product.

[0032] The front end refers to the core of disposable hygiene products being rolled by the first composite pressure roller Y1 before being processed by the second feeding mechanism G2.

[0033] Furthermore, a composite transmission mechanism C2 for composite and conveying is also provided at the rear end of the first composite pressure roller Y1.

[0034] The core of the disposable hygiene product, which is composite-molded here, consists of a bottom non-woven fabric, a first layer of polymer on the bottom non-woven fabric and fluffy cotton, a second layer of polymer on the fluffy cotton, and a dust-free paper. It is then rolled and conveyed again by the composite conveyor mechanism C2, which can use a common conveyor belt. The rear end refers to the process where the core of the disposable hygiene product is first processed by the second composite pressure roller Y2, and then by the composite conveyor mechanism C2.

[0035] Furthermore, the rear end of the composite transmission mechanism C2 is also equipped with an edge-sealing glue spraying mechanism J4 and an edge-sealing mechanism B1. The edge-sealing glue spraying mechanism J4 sprays glue on the edge, and the edge-sealing mechanism B1 performs edge-sealing treatment on the product.

[0036] Furthermore, the finishing material conveying mechanism C3 is also installed at the rear end of the edge-binding mechanism B1.

[0037] Furthermore, the first feeding mechanism G1 and the second feeding mechanism G2 include a storage bin 4, a roller 3, and a feeding bin 2. The storage bin 4 is equipped with a rotatable roller 3, and the bottom of the storage bin 4 is an open opening that is connected to the feeding bin 2.

[0038] The first feeding mechanism G1 and the second feeding mechanism G2 have the same structure. They store polymers through the storage bin 4 and use a motor to drive the roller 3 to rotate, so that the polymers are slowly transferred to the open opening at the bottom of the storage bin 4. Finally, they enter the feeding bin 2 and cooperate with the adsorption chamber X1 on the adsorption mold wheel 1 to adsorb and feed the polymers.

[0039] Furthermore, the feeding bin 2 has a feed inlet 22 through its side wall, and the feeding bin 2 is connected to the storage bin 4 through the feed inlet 22. The bottom of the feeding bin 2 is connected to the adsorption mold wheel 1.

[0040] Furthermore, a pressure relief port 21 is provided through the top of the feeding hopper 2 to prevent excessive negative pressure inside the feeding hopper 2, so that the polymer can fall evenly and stably onto the corresponding position of the bottom nonwoven fabric.

[0041] Furthermore, multiple adsorption chambers X1 are provided, and they are divided and coordinated in different areas.

[0042] Furthermore, the adsorption chamber X1 is provided with three chambers: a first adsorption chamber A, a second adsorption chamber B, and a third adsorption chamber C. The first adsorption chamber A is coordinated with the first feeding mechanism G1, the second adsorption chamber B is coordinated with the second conveying mechanism L2, and the third adsorption chamber C is coordinated with the second feeding mechanism G2.

[0043] The bottom layer of nonwoven fabric (dust-free paper) is fed in, and adhesive is sprayed onto the surface of the nonwoven fabric through the first adhesive spraying mechanism J1. After passing through the adsorption chamber X1 of the adsorption mold wheel 1, a negative pressure is generated on the surface of the nonwoven fabric (dust-free paper), which adsorbs the polymer in the feeding bin 2 (first feeding mechanism G1) and feeds it onto the nonwoven fabric (dust-free paper) with adhesive. Then, the second conveying mechanism L2 cooperates with the second adhesive spraying mechanism J2 to spray adhesive onto the fluffy cotton output by the second conveying mechanism L2. The fluffy cotton after adhesive spraying is sprinkled on the aforementioned polymer surface and is compounded by the first composite pressure roller Y1 at the front end of the second feeding mechanism G2. Afterwards, another feeding bin 2 in the second feeding mechanism G2 continues to feed polymer, and adhesive is sprayed onto the dust-free paper through the dust-free paper feeding mechanism L3 and the dust-free paper adhesive spraying mechanism J3. The polymer in the second feeding mechanism G2 is compounded with the dust-free paper after adhesive spraying, and finally the edge is bound by the edge binding mechanism B1.

[0044] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
