[0002] Absorbent cores, as one of the essential raw materials for hygiene products, play an indispensable role. In daily life and healthcare, absorbent cores are widely used in various hygiene products, providing strong support for people's healthy lives.
[0003] Absorbent cores are favored by users for their excellent absorbency and durability. During manufacturing, special processes and high-quality raw materials are used to give them extremely strong absorbency, quickly absorbing and locking in moisture to effectively keep sanitary products dry and clean. Whether it's sanitary napkins, diapers, or feminine hygiene products, they all rely on this highly efficient absorbent core.
[0004] In sanitary napkins, the absorbent core is particularly widely used. It quickly absorbs and locks in menstrual fluids, keeping the napkin dry and comfortable, effectively preventing side leakage and seepage, and providing women with a better user experience. Furthermore, the absorbent core also has antibacterial and deodorizing properties, helping to maintain personal hygiene and health.
[0005] In the medical field, absorbent cores also play a vital role. In products such as diapers, they effectively absorb and retain urine and other liquids, reducing the embarrassment and discomfort caused by soaked clothing and sheets. Furthermore, the use of absorbent cores can effectively prevent complications such as eczema, providing strong support for patient recovery.
[0006] With the continuous advancement of technology and people's increasing demands for quality of life, the manufacturing technology of absorbent cores is also constantly developing and innovating.
[0007] Chinese patent CN118697557A discloses a novel absorbent core and its preparation method. From top to bottom, it comprises a hot-air nonwoven fabric and a C-shaped composite layer, bonded together by an adhesive. The C-shaped composite layer is formed by folding and bonding the top and bottom layers together—a permeable layer, an absorbent layer, and a support layer—with both sides facing upwards. The C-shaped composite layer has a groove in the middle. The permeable layer, absorbent layer, and support layer are bonded together by an adhesive. The permeable layer is made of toilet paper or plant fiber. The absorbent layer consists of a fluffy nonwoven fabric and a superabsorbent polymer uniformly permeated within the fluffy nonwoven fabric. The support layer is made of spunbond nonwoven fabric. The C-shaped composite layer allows liquid to diffuse outwards and be absorbed by the sides, achieving excellent anti-slip properties and reducing the diffusion rate to some extent, thus preventing leakage.
[0008] However, current technology lacks equipment capable of rapidly manufacturing foldable C-shaped composite absorbent cores to improve production efficiency and enhance the quality of hygiene products. Utility Model Content
[0009] The technical problem to be solved by this utility model is to provide a folding device for absorbent cores, which can quickly manufacture C-shaped composite layer absorbent cores that need to be folded, effectively improving production efficiency and enhancing the quality of hygiene products.

[0026] To make the objectives, technical solutions and advantages of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings.
[0027] like Figures 1 to 3 As shown, an absorbent core folding device includes a workbench 1, on which a first conveying device 2 and a folding device 3 are installed. The first conveying device 2 includes a first paper feeding roller, and the folding device 3 includes an adjusting roller 31, a folding guide 32, a folding groove 33, and a folding stop 34. The first paper feeding roller is located to the left of the adjusting roller 31, and the width of the first paper feeding roller is greater than the width of the adjusting roller 31. The folding groove 33 is located to the right of the adjusting roller 31, and the folding stop 34 is fixedly installed on the top of the folding groove 33. A fixing plate 35 is fixedly installed above the folding stop 34, and the folding guide 32 is fixedly installed on the fixing plate 35. The folding guide 32 gradually converges from the adjusting roller 31 towards the folding part 63, and its end near the adjusting roller 31 is an open end. The size of the opening end of the adjusting roller 31 matches that of the folding guide 32. The folding of the absorbent core is achieved through the cooperation of the adjusting roller 31 and the folding guide 32. The folding groove 33 and the folding stop 34 work together to shape the folded absorbent core, ensuring the folding efficiency and quality of the absorbent core. The folding device 3 quickly folds the absorbent core into a C-shaped composite layer, thereby effectively improving the production efficiency of the C-shaped composite layer absorbent core 6. The C-shaped composite layer can achieve a good anti-slip effect and also reduce the diffusion speed to a certain extent, making it less prone to leakage. By quickly manufacturing the C-shaped composite layer absorbent core 6 that needs to be folded, the high-quality production of sanitary napkins and diapers can be accelerated.
[0028] The workbench 1 is also equipped with a support frame 36, and the folding groove 33 is installed on the support frame 36.
[0029] There are two first paper feeding rollers, which rotate at the same linear speed and are spaced apart.
[0030] The workbench 1 is also equipped with a second conveying device 4 and a composite device 5. The composite device 5 includes a composite roller 51 and a compaction roller 52. The composite roller 51 is located to the right of the folding device 3 and has flanges at both ends. The compaction roller 52 is located to the right of the composite roller 51 and consists of two rotating rollers that are matched vertically. The composite device 5 can quickly combine the folded C-shaped composite layer with the surface layer 61 to form a complete C-shaped composite layer absorbent core 6, effectively improving the production speed of the C-shaped composite layer absorbent core 6.
[0031] The second conveying device 4 includes a second paper feed roller 41.
[0032] The second conveying device 4 also includes a first tension roller 42, which is located between the second paper feed roller 41 and the composite roller 51. The first tension roller 42 can ensure that the surface layer is more firmly attached and less prone to displacement.
[0033] Reference Figure 1-3 It also includes a glue spraying device 7, which is located to the side of the first tensioning roller 42 and the composite roller 51. The nozzle of the glue spraying device 7 is the same width as the surface layer to be laminated placed on the first tensioning roller 42. The glue sprayed onto the surface layer by the glue spraying device 7 makes the surface layer and the C-type composite layer more firmly bonded.
[0034] The second conveying device 4 further includes a second tension roller 43, which is located between the first tension roller 42 and the composite roller 51. The glue spraying device 7 is located to the side of the first tension roller 42 and the second tension roller 43. The second tension roller 43 can ensure the flatness of the composite surface layer when the composite roller 51 is used for lamination.
[0035] like Figure 4 As shown, the C-type composite layer absorbent core 6 produced by this utility model includes a C-type composite layer and a surface layer 61 from bottom to top. The C-type composite layer includes a bottom layer 62, folded portions 63 located on both sides of the top of the bottom layer 62, and grooves 64 located between the folded portions 63.
[0036] The method of using a water-absorbing core folding device is as follows:
[0037] like Figure 1 As shown, firstly, when the composite layer material to be folded is used for the first time, it is manually assembled from beginning to end into the first conveying device 2 and the folding device 3. The composite layer material passes through the top of the first conveying device 2 to the bottom of the adjusting roller 31, then is inserted into the opening end of the folding guide 32, and then passes through the folding groove 33. At this point, the device can achieve automatic folding without manual traction. The adjusting roller 31 and the folding guide 32 cause the two sides of the material to be folded to curl up, and the curled edges are gathered by the folding guide 32 to form the folding part 63 of the composite layer material, and then enter the folding groove 33 to complete the shaping, forming a folded C-shaped composite layer. The folded part is then conveyed forward to the composite roller 51 to be laminated with the surface layer 61 conveyed by the second conveying device 4. The surface layer 61 conveyed by the second conveying device 4 is first conveyed to the first tensioning roller 42 for tensioning. Then, the glue spraying device 7 sprays glue onto the surface of the surface layer 61 opposite to the C-shaped composite layer. After that, the surface layer 61 is tensioned by the second tensioning roller 43 and enters the composite roller 51 together with the C-shaped composite layer. The composite roller 51 makes the C-shaped composite layer (62, 63, 64) and the surface layer 61 composite. Then, it is compacted by the compaction roller 52 to complete the composite of the folded material and the surface layer 61. After cutting, the C-shaped composite layer water-absorbing core 6 is obtained.
[0038] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
