Abstract
Description
Technical Field
[0001] This utility model relates to the field of diaper production equipment technology, and more specifically to a cotton core pressing device. Background Technology
[0002] The core technology of disposable diapers is the core. Disposable diapers are single-use products made of non-woven fabric, toilet paper, fluff pulp, superabsorbent polymer (SAP), PE film, and elastic bands. After the core is made, it needs to be pressed to make it thinner for subsequent processes. Most existing pressing devices use two vacuum turntables for pressing. In actual use, the following problems have been found: First, different diaper models require different pressing thicknesses, which is not easy to adjust with existing pressing devices. Second, pressing can easily result in pressing that is too tight or too loose, leading to a low yield of cores. These have become problems that manufacturers urgently need to solve. To address these issues, we have proposed a cotton core pressing device. The device uses a slide rail on the turntable to adjust the pressing thickness as needed, and elastic blocks on the turntable provide tension during pressing, improving the yield.
[0003] To effectively press the absorbent core, Chinese patent application CN213666179U discloses a pressing device for a polymer absorbent core in diapers. This invention includes a platform with a frame fixedly mounted on its top. A gear is rotatably mounted on one side of the top of the frame, with a rack meshing with the gear's outer side. The rack is slidably mounted on the top of the frame, and a connecting rod is fixedly mounted on the outer side of the rack. The bottom end of the connecting rod extends into the frame and is rotatably mounted with a pressing roller. A worm gear is rotatably mounted on one side of the top of the frame, and a partially worm gear is rotatably mounted on the same side, meshing with the worm gear. The rear side of the worm gear is fixedly mounted on the front side of the gear. A rotating rod is rotatably mounted inside the frame, with a fan blade fixedly mounted at one end. Both the other end of the rotating rod and the end of the partially worm gear are fixedly mounted with pulleys, and the two pulleys are connected by the same belt. This invention, through the use of pulleys, allows the drying of the absorbent material and the pressing of the absorbent core to proceed synchronously, thereby improving work efficiency.
[0004] The solution still has some shortcomings in application. Since the core is made continuously, it needs to be pressed quickly, otherwise it will easily affect production efficiency. At the same time, the pressing thickness needs to be flexibly adjusted according to different product characteristics, otherwise the yield will be low. Therefore, the structure of the pressing equipment needs to be improved to enable it to press quickly, with good pressing effect and high yield, effectively improving the practical performance of the pressing equipment.

Next, a crossbar is located in the middle of the second vacuum turntable, which can slide left and right along a transverse slide rail to adjust the distance between the pressing ring and the pressing groove. This allows for adjustment of the pressing thickness of the core to meet different production requirements. Finally, a fan-shaped block is built into the second vacuum turntable, and a spring is installed between the fan-shaped block and the circular disc to provide tension to the pressing ring, preventing over-pressing and resulting in a low yield. This invention features a novel structure, fast pressing speed, good effect, strong practicality, and is suitable for widespread application. Attached Figure Description

[0019] like Figures 1 to 3 As shown, a cotton core pressing device includes a frame 1, a first vacuum turntable 2, and a second vacuum turntable 3. Both the first vacuum turntable 2 and the second vacuum turntable 3 are fixed on the frame 1. A core cavity 4 is provided above the first vacuum turntable 2, and a rotating roller 5 is placed inside the core cavity 4. The side of the first vacuum turntable 2 has an "I"-shaped structure, and a pressing groove 6 is provided in the middle of the "I"-shaped structure. A transverse slide rail 7 is provided on the right side of the first vacuum turntable 2. A slide rod 31 is provided in the middle of the second vacuum turntable 3, and the slide rod 31 is embedded in the transverse slide rail 7. A circular disk 8 is provided in the middle of the second vacuum turntable 3, and a spring 9 is provided on the outside of the circular disk 8. Four fan-shaped blocks 10 are installed at the end of the spring 9. A pressing ring 11 is sleeved on the outside of the fan-shaped blocks 10, and the pressing ring 11 is correspondingly arranged with the pressing groove 6.
[0020] Furthermore, a number of perforations 12 are arranged on one side of the first vacuum turntable 2, and a dust cover 13 is fitted on the outside of the frame 1, with an air intake 14 on the top of the dust cover 13.
[0021] Furthermore, a fabric feeding device 15 is installed at the bottom of the frame 1, and a fabric 16 is provided at the outlet of the fabric feeding device 15. The fabric 16 is flush with the bottom of the second vacuum turntable 3.
[0022] Furthermore, the rotating roller 5 is equipped with a core 17, which is arranged in an inverted "S" shape around the first vacuum turntable 2 and the second vacuum turntable 3 and is in contact with the fabric 16.
[0023] Furthermore, an adjustable roller 18 is provided on one side of the core 17 cavity, and the adjustable roller 18 is correspondingly arranged with the first vacuum turntable 2.
[0024] Furthermore, a limiting nut 19 is provided at the end of the slide bar 31, and the second vacuum turntable 3 can be fixed on the transverse slide rail 7 by means of the limiting nut 19.
[0025] [Example]
[0026] First, the core 17 is rolled up and placed on the roller 5 inside the core cavity 4, extending from the outlet on one side of the core cavity 4 to the first vacuum turntable 2. The core 17 is wound in an inverted "S" shape on the first vacuum turntable 2 and the second vacuum turntable 3, with its bottom in contact with the fabric 16 of the fabric device 15. Next, according to the thickness to be pressed, the second vacuum turntable 3 is adjusted left and right along the transverse slide rail 7. This adjustment adjusts the distance between the pressing ring 11 and the pressing groove 6, thereby adjusting the pressing thickness. Finally, the second vacuum turntable 3 rotates, causing the core 17 to rotate. The core 17 is rapidly pressed between the pressing groove 6 and the pressing ring 11. Since the pressing ring 11 has a fan-shaped block 10 inside, and a spring 9 is provided between the fan-shaped block 10 and the circular disc 8, the pressing ring 11 has a certain tension, preventing the core 17 from being over-pressed and resulting in a low yield. At the same time, the cotton lint generated during the pressing process is collected by the dust cover 13 and sucked out from the suction port 14 to avoid contamination.
