Description

Technical Field

[0001] This utility model relates to the field of tissue paper production technology, and in particular to an embossing device for tissue paper production. Background Technology

[0002] As a daily necessity, the market demand for facial tissues continues to grow with the upgrading of consumption, and consumers are placing higher demands on the aesthetics, comfort, and functionality of the products. Embossing is a key step in improving the quality of facial tissues. By creating three-dimensional patterns on the surface of the paper, it can enhance the tactile feel, absorbency, and visual effect, while also meeting the needs of brand differentiation.

[0003] Traditional embossing rollers are integrated into a fixed frame. Replacing them requires disassembling multiple sets of connecting parts (such as bolts and couplings), involving complex operations such as mechanical alignment and dynamic balancing. This is difficult for non-professionals to complete, and frequent disassembly and assembly accelerates equipment wear. Utility Model Content

Both ends of the lower rotating rod penetrate the vertical plate and are rotatably connected to its bearings. A hydraulic cylinder is embedded and fixedly connected to the bottom inner wall of the cross hole, and the output end of the hydraulic cylinder is fixedly connected to the bottom of the cross plate.

The rotation of the patterned roller 18 and the raised patterned roller 19 is achieved by having cross holes 12 on the surface of the vertical plate 11 near the top. A cross plate 13 is embedded inside each cross hole 12. Both ends of the upper rotating rod 17 pass through the cross plate 13 and are rotatably connected to its bearings.

[0029] The overall effect of embodiment 2 is as follows: Support legs 2 are fixedly connected to the bottom of the top plate 1 near its four corners. The bottom of each support leg 2 is trapezoidal, allowing it to support the bottom of the top plate 1. U-shaped plates 4 are fixedly connected to the top of the top plate 1 near both ends. Two limiting rollers 5 are embedded inside the U-shaped plates 4 and rotatably connected by bearings, allowing them to limit the paper position. Four mounting holes 9 are provided at both ends of the square rotating plate 8. Mounting plates 10 are fixedly connected to the bottom of the fixing plate 6, and round holes are provided on the surface of each mounting plate 10, allowing them to be installed and fixed. The tops of the U-shaped plates 4 and the vertical plates 11 are rounded to prevent sharp corners from injuring people.

[0030] Working principle: The rotating column 7 can be manually driven to push the vertical plate 11 to rotate. The rotation of the rotating column 7 can cause the square rotating plate 8 to rotate 90° around the rotating column 7. Different patterns are preset on the four sides of the embossing roller group to be worked. The square rotating plate 8 is positioned by passing bolts through the mounting holes 9 and mounting plates 10. At this time, the hydraulic cylinder 15 drives the cross plate 13 to descend along the vertical rod 14, so that the raised pattern roller 19 of the upper rotating rod 17 fits against the concave pattern roller 18 of the lower rotating rod 17. At this time, the cross plate 13 will squeeze the pressure sensor 16. The pressure sensor 16 collects pressure data in real time and feeds it back to the controller to dynamically adjust the tension of the hydraulic cylinder 15 to stabilize the embossing depth. Two sets of drive motors 20 are connected to the upper and lower rotating rods 17 respectively. The main motor speed is used as the reference of the slave motor through encoder signal interlock. Combined with PID speed regulation algorithm, it is ensured that the speed of the two rollers is consistent in real time. Even if the load fluctuates, it can quickly compensate. For example, when paper is piled up on one side, the slave motor automatically increases the frequency to catch up.

[0031] The wiring diagrams of the hydraulic cylinder 15, pressure sensor 16, concave pattern roller 18, convex pattern roller 19, and drive motor 20 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring arrangements of the hydraulic cylinder 15, pressure sensor 16, concave pattern roller 18, convex pattern roller 19, and drive motor 20 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
