Description

Technical Field

[0001] This utility model relates to the field of disposable hygiene product production equipment, and in particular to an adult diaper compaction device. Background Technology

[0002] The cotton core is mainly composed of superabsorbent polymer (SAP) and wood pulp fibers, and its compaction effect directly determines the absorbency, comfort, and overall structural stability of the diaper. Traditional adult diaper compaction devices have several limitations in structure and function. Firstly, in the material delivery and mixing stage, traditional devices struggle to achieve precise and uniform delivery and mixing of SAP and wood pulp fibers, resulting in uneven material distribution within the cotton core and affecting the consistency of absorbency. Secondly, during the compaction process, the lack of an effective compaction mechanism and a reasonable transfer channel design leads to insufficient and uneven compaction of the cotton core, easily resulting in localized loosening or over-compaction, thus affecting the diaper's comfort and absorbency. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model provides an adult diaper compaction device that accurately and uniformly conveys and mixes materials and has a good compaction effect.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An adult diaper compaction device includes a superabsorbent polymer (SAP) suction assembly, a SAP feeding assembly, a wood pulp fiber suction assembly, a feeding bin, a forming die wheel assembly, a first transfer wheel, a cotton core pressing assembly, a second transfer wheel, and an adsorption conveying assembly. The SAP feeding assembly is located at the output end of the SAP suction assembly. The feeding bin has a first inlet, a second inlet, and an outlet. The output ends of the SAP feeding assembly and the wood pulp fiber suction assembly are respectively connected to the first and second inlets of the feeding bin. The forming die wheel assembly is located at the outlet of the feeding bin. The first transfer wheel is located at the output end of the forming die wheel assembly. The cotton core pressing assembly and the second transfer wheel are located at the output ends of the first transfer wheel. The pressing and conveying components are distributed around the second transfer wheel, forming a first transfer channel between the cotton core pressing and conveying components and the second transfer wheel. The cotton core pressing and conveying components include a support, a first drive mechanism, a pressure roller, several first guide rollers, a first tension roller mechanism, a first mesh belt, and a drive cylinder. The drive cylinder is mounted on the support, and the pressure roller is located at the output end of the drive cylinder and distributed around the second transfer wheel. The first drive mechanism is connected to the pressure roller and is used to drive the pressure roller to rotate. The first guide rollers and the first tension roller mechanism are distributed around the second transfer wheel. The first mesh belt is wound around the pressure roller, the first guide rollers, and the first tension roller mechanism, so that a portion of the first mesh belt covers a portion of the circumferential surface of the second transfer wheel. The adsorption and conveying component is located at the output end of the cotton core pressing and conveying components and the second transfer wheel.

[0006] Furthermore, the forming die wheel assembly includes a drive roller, a forming die wheel, a second tension roller mechanism, a plurality of second guide rollers, and a second mesh belt. The second tension roller mechanism and the second guide rollers are both located on the periphery of the forming die wheel. The second mesh belt is wound around the forming die wheel, the drive roller, the second tension roller mechanism, and the second guide rollers, and a portion of the second mesh belt covers a portion of the circumferential surface of the first transfer wheel, thereby forming a second transfer channel between the second mesh belt and the first transfer wheel.

[0007] Furthermore, the forming mold wheel assembly also includes a mold wheel cleaning mechanism, which is located between the forming mold wheel and the second mesh belt.

[0008] Furthermore, the discharge port of the feeding hopper is equipped with a uniform brush for smoothing the wood pulp fibers on the forming mold wheel assembly.

[0009] Furthermore, the adsorption conveying assembly includes an adsorption conveying box mechanism and a pulley conveying mechanism disposed on the upper side of the adsorption conveying box mechanism, and a third transfer channel is formed between the pulley conveying mechanism and the adsorption conveying box mechanism.

[0010] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: This adult diaper compaction device, through the setting of a superabsorbent polymer suction component, a feeding component, a wood pulp fiber suction component, and a feeding bin, achieves independent suction and precise feeding of superabsorbent polymer and wood pulp fiber, and effectively mixes the two materials in the feeding bin, providing a uniform raw material base for subsequent molding, which helps to improve the quality stability of the diaper core; the molding die wheel component, the first transfer wheel, the core pressing and conveying component, the second transfer wheel, and the adsorption conveying component are arranged sequentially to form a scientific and reasonable material transfer and compaction flow. In the process, the cotton core is gradually transferred and compacted between various components. In particular, the cotton core pressing component, through the cooperation of structures such as the support, drive cylinder, pressure roller, and first mesh belt, can precisely control the pressure of the pressure roller on the cotton core according to production needs, so that the cotton core is compacted evenly, improving the overall structural strength and absorbency of the diaper. At the same time, the first transfer channel formed between the cotton core pressing component and the second transfer wheel ensures that the cotton core maintains a stable shape during the transfer process and is continuously subjected to compaction, further improving the compaction quality of the cotton core and providing a strong guarantee for the production of high-quality adult diapers.

[0014] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0015] The embodiment of this utility model is as follows:

[0016] refer to Figure 1 , Figure 2 and Figure 3As shown, an adult diaper compaction device includes a superabsorbent polymer (SAP) suction assembly 1, a SAP feeding assembly 2, a wood pulp fiber suction assembly 3, a feeding bin 4, a forming die wheel assembly 5, a first transfer wheel 6, a core pressing and conveying assembly 7, a second transfer wheel 8, and an adsorption and conveying assembly 9. The SAP feeding assembly 2 is located at the output end of the SAP suction assembly 1. The feeding bin 4 has a first inlet 41, a second inlet 42, and an outlet 43. The output ends of the SAP feeding assembly 2 and the wood pulp fiber suction assembly 3 are respectively connected to the first inlet 41 and the second inlet 42 of the feeding bin 4. The forming die wheel assembly 5 is located at the outlet 43 of the feeding bin 4. The first transfer wheel 6 is located at the output end of the forming die wheel assembly 5. The core pressing and conveying assembly 7 and the second transfer wheel 8 are located at the output end of the first transfer wheel 6, and the core pressing and conveying assembly 7 is distributed... A first transfer channel 10 is formed between the cotton core pressing assembly 7 and the second transfer wheel 8 on the periphery of the second transfer wheel 8. The cotton core pressing assembly 7 includes a bracket 71, a first drive mechanism, a pressure roller 73, several first guide rollers 74, a first tension roller mechanism 75, a first mesh belt 76, and a drive cylinder 77. The drive cylinder 77 is mounted on the bracket 71. The pressure roller 73 is located at the output end of the drive cylinder 77 and distributed on the periphery of the second transfer wheel 8. The first drive mechanism is connected to the pressure roller 73 and is used to drive the pressure roller 73 to rotate. The first guide rollers 74 and the first tension roller mechanism 75 are distributed on the periphery of the second transfer wheel 8. The first mesh belt 76 is wound around the pressure roller 73, the first guide rollers 74, and the first tension roller mechanism 75, so that a portion of the first mesh belt 76 covers a portion of the circumferential surface of the second transfer wheel 8. The adsorption conveying assembly 9 is located at the output end of the cotton core pressing assembly 7 and the second transfer wheel 8.

[0017] This adult diaper compaction device, through the inclusion of a superabsorbent polymer (SAP) suction component 1, a SAP feeding component 2, a wood pulp fiber suction component 3, and a feeding bin 4, achieves independent suction and precise feeding of SAP and wood pulp fibers. The two materials are effectively mixed in the feeding bin, providing a uniform raw material base for subsequent molding and contributing to improved quality stability of the diaper core. The sequential arrangement of the forming die wheel component 5, the first transfer wheel 6, the core pressing and conveying component 7, the second transfer wheel 8, and the adsorption and conveying component 9 forms a scientifically sound material transfer and compaction process, with the core moving between these components. The cotton core is gradually transferred and compacted. In particular, the cotton core conveying assembly 7, through the cooperation of the support 71, drive cylinder 77, pressure roller 73, and first mesh belt 76, can precisely control the pressure of the pressure roller 73 on the cotton core according to production needs, so that the cotton core is compacted evenly, improving the overall structural strength and absorbency of the diaper. At the same time, the first transfer channel 10 formed between the cotton core conveying assembly 7 and the second transfer wheel 8 ensures that the cotton core maintains a stable shape during the transfer process and is continuously compacted during the transfer process, further improving the compaction quality of the cotton core and providing a strong guarantee for the production of high-quality adult diapers.

[0018] Specifically, the forming die wheel assembly 5 includes a drive roller 51, a forming die wheel 52, a second tension roller mechanism 53, several second guide rollers 54, and a second mesh belt 55. The second tension roller mechanism 53 and the second guide rollers 54 are both located on the periphery of the forming die wheel 52. The second mesh belt 55 is wound around the forming die wheel 52, the drive roller 51, the second tension roller mechanism 53, and the second guide rollers 54, and a portion of the second mesh belt 55 covers a portion of the circumferential surface of the first transfer wheel 6, thereby forming a second transfer channel 50 between the second mesh belt 55 and the first transfer wheel 6. The drive roller 51, the forming die wheel 52, the second tension roller mechanism 53, the second guide rollers 54, and the second mesh belt 55 in the forming die wheel assembly 5 cooperate with each other, so that a portion of the second mesh belt 55 covers a portion of the circumferential surface of the first transfer wheel 6, forming the second transfer channel 50. This design allows the material from the feeding hopper 4 to be initially formed on the forming die wheel 52 and then smoothly transferred to the first transfer wheel 6. This reduces deformation and damage during the transfer process, improving the accuracy and stability of the forming. The second mesh belt 55 not only transfers the material in the forming die wheel assembly 5 but also provides support and assists in the forming process. During the forming process around the forming die wheel, the second mesh belt 55 maintains the shape of the material, preventing it from becoming loose or deformed. This helps to form a uniform and stable cotton core preliminary forming body, laying a good foundation for the subsequent compaction process.

[0019] Furthermore, the forming die wheel assembly 5 also includes a die wheel cleaning mechanism 56, which is located between the forming die wheel 52 and the second mesh belt 55. This cleaning mechanism 56, situated between the forming die wheel 52 and the second mesh belt 55, effectively cleans away impurities, fibers, and other substances remaining on the surface of the forming die wheel 52. This effectively prevents uneven material forming and surface defects caused by unclean die wheel surfaces, ensuring the forming quality of each cotton core, improving product qualification rate, extending the service life of the forming die wheel, and reducing production costs.

[0020] Furthermore, the discharge port 43 of the feeding hopper 4 is equipped with a uniform brush 11 for smoothing the wood pulp fibers on the forming mold wheel assembly. The uniform brush 11 at the discharge port 43 of the feeding hopper 5 can smooth the wood pulp fibers on the forming mold wheel assembly 5. During the process of material being output from the feeding hopper 4 to the forming mold wheel 52, the uniform brush 11 can comb the wood pulp fibers, making their distribution more uniform and avoiding fiber accumulation or uneven distribution. This improves the uniformity of the material inside the cotton core, further enhancing the absorbency and comfort of the diaper.

[0021] In this embodiment, the adsorption conveying assembly 9 includes an adsorption conveying box mechanism 91 and a pulley conveying mechanism 92 disposed on the upper side of the adsorption conveying box mechanism 91. A third transfer channel 90 is formed between the pulley conveying mechanism 92 and the adsorption conveying box mechanism 91. The third transfer channel 90 formed between the two provides a stable conveying environment for the compacted cotton core. The adsorption conveying box mechanism 91 can fix the cotton core through adsorption, preventing it from shifting or deforming during the conveying process. At the same time, the pulley conveying mechanism 92 can smoothly convey the cotton core to the next process, ensuring the quality stability of the diaper cotton core before final molding, which helps to improve the continuity and stability of the entire production process and improve the overall quality of the product.
