Description

Technical Field

[0001] This utility model relates to the field of diaper production equipment technology, and more specifically to an embossing device applied to diaper processing. Background Technology

[0002] The surface of diapers often features embossing designs, which are created by using special processing techniques to form a series of tiny raised and recessed patterns on the diaper's surface material. The comfort and quality of diapers are often closely related to the embossing process on their surface. Different brands of diapers use different embossing designs for their surface layers, but all aim to enhance the surface layer's performance. Embossing improves the diaper's absorption speed; the grooves in the embossing accelerate urine penetration, promoting rapid absorption to the next layer and preventing urine from remaining on the surface for extended periods, thus reducing discomfort for the baby and increasing absorbency. However, existing diaper embossing equipment often encounters the following problems: firstly, the diaper surface layer is not sufficiently taut when entering the embossing assembly, easily causing wrinkles that affect the embossing process; secondly, the embossing assembly is located at the top of the frame, making it difficult to view and maintain, and prolonged operation can lead to overheating and malfunctions, impacting production. To address these issues, we propose an embossing device for diaper processing. By adding a straightening device, the surface layer is taut before embossing, facilitating the subsequent embossing process. Simultaneously, the embossing assembly is separated to one side of the frame for easier viewing and maintenance, further improving the practicality of the embossing equipment.

[0003] To improve the absorbency of diapers by embossing the surface layer, Chinese patent application (publication number CN221339568U) discloses an embossing machine for baby diaper production. This invention includes a worktable and an embossing roller. A conveyor belt is installed on the inner wall of the worktable. During disassembly, rotating the limiting component moves it away from the embossing roller, releasing the two trapezoidal blocks from restricting the second cross pin block. Then, pulling the operating block causes the second cross pin block to slide away from the embossing roller, releasing the pressure... The embossing roller has a snap-fit ​​function. Then, the other end of the embossing roller can be pulled out. During installation, one end of the embossing roller is snapped into the first cross pin block. Then, the operating block is pulled to drive the second cross pin block to move. When it is aligned with the cross slot at the other end of the embossing roller, the operating block is released, and then the compression component is reset under its elasticity, which in turn drives the second cross pin block to move. Then, the two trapezoidal snap blocks are pressed into the sliding hole, and the limiting component is rotated to limit the two trapezoidal snap blocks. This utility model can quickly and effectively emboss diapers.

[0004] The solution still has some shortcomings in application. Because the diaper surface must be kept taut before entering the embossing assembly, otherwise the surface may not be taut and wrinkles may occur, resulting in uneven embossing and poor effect. At the same time, the embossing assembly is often located on the top of the frame, which is inconvenient for maintenance and viewing of instrument values, which is not conducive to production. Therefore, the structure of the embossing equipment needs to be improved to enable it to achieve fast, stable, neat and good embossing, while also facilitating daily operation and maintenance by workers, effectively improving the practicality of the embossing equipment.

[0019] like Figures 1 to 3 As shown, an embossing device for diaper processing includes a surface layer frame 1, a straightening frame 2, an embossing frame 3, and a receiving frame 4. The surface layer frame 1, the straightening frame 2, the embossing frame 3, and the receiving frame 4 are arranged sequentially from front to back. The surface layer frame 1 is equipped with a roller 11, on which a roll of surface layer 12 is mounted. The straightening frame 2 is equipped with a cylinder 21 at its top, with the driving end of the cylinder 21 pointing downwards and the end equipped with a retractable pressure plate 5. A fixing plate 6 is located below the retractable pressure plate 5. The top of the embossing frame 3 is equipped with several ultrasonic embossing components 31. An instrument box 7 is located on one side of the embossing frame 3, and several instruments 8 are correspondingly mounted on the instrument box 7.

[0025] [Example]

[0026] First, the surface layer 12 is wound onto the roller 11 on the surface layer frame 1 and conveyed to the straightening frame 2 by the drive motor 13 of the surface layer frame 1. The surface layer 12 passes through the straightening frame 2, and the telescopic pressure plate 5 is pressed downward by the cylinder 21. The surface layer 12 is pressed between the fixed plate 6 and the lower plate 52 for straightening. The fixed plate 6 and the lower plate 52 are heated by the heater 10, which can better heat the surface layer 12 and make the surface layer 12 straighter. Then, after being heated and straightened, the surface layer 12 enters the ultrasonic embossing assembly 31 of the embossing frame 3, and is then subjected to ultrasonic embossing. The ultrasonic embossing component 31 is connected to the instrument 8 in the instrument box 7. The embossing value can be viewed from the instrument 8 and can also be adjusted through the upper operation panel 71. It is also convenient to maintain in case of failure. Finally, the embossed surface layer 12 enters the receiving rack 4 and is received by the drive motor 13 of the receiving rack 4. During embossing, cold air enters from the cold air inlet 73 at the top of the instrument box 7 to keep the control panel 71 and the instrument 8 at a constant temperature, avoid overheating and failure due to long-term operation, and ensure continuous and efficient operation.

[0027] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:
