Description

Technical Field

[0001] This utility model relates to the field of household paper production technology, and in particular to a single-sided embossing composite device for household paper production. Background Technology

[0002] As daily necessities, the functionality (such as absorbency and softness) and appearance (such as embossing texture) of household paper directly impact the consumer experience. Single-sided embossing technology, by creating a three-dimensional pattern on one side of the paper surface, not only enhances the product's visual appeal but also strengthens specific properties through structural design—for example, a fluffy embossed layer can improve the absorbency of hand towels, while shallow embossed patterns give napkins a more premium feel. With the upgrading of consumption, the market has placed higher demands on the precision of embossing processes, production efficiency, and ease of equipment maintenance.

[0003] In existing single-sided embossing equipment, the matching use of embossing rollers and back pressure rollers is the core to achieving pattern formation. However, in traditional devices, paper fiber debris easily accumulates in the grooves of the embossing rollers during the embossing process, leading to blurred or even blocked subsequent embossing. This requires frequent machine shutdowns for manual cleaning, severely restricting continuous production efficiency. Furthermore, the embossing rollers need to be replaced periodically after long-term use, but traditional installation structures rely on bolt fixing and precise alignment, making replacement procedures cumbersome. To address these issues, we propose a single-sided embossing composite device for tissue paper production. Utility Model Content

[0004] The present invention mainly addresses the technical problems existing in the prior art, and provides a single-sided embossing composite device for the production of household paper, which solves the problems of frequent cleaning of single-sided embossing rollers and inconvenience in replacing embossing rollers during use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a single-sided embossing and laminating device for the production of household paper, comprising a processing table, two symmetrically arranged first fixed plates fixedly installed at one end of the upper surface of the processing table, two sets of conveying rollers arranged between the two first fixed plates, and two symmetrically arranged third fixed plates fixedly installed at the other end. Back pressure rollers are rotatably installed on the upper ends of the two third fixed plates. Second fixed plates are fixedly installed on both outer walls of the processing table outside the third fixed plates. Detachable embossing rollers are movably installed on the upper ends of the two second fixed plates. A cleaning component for cleaning the surface of the embossing rollers is also provided between the upper halves of the second fixed plates. The cleaning component includes a threaded rod with both ends rotatably connected to the two second fixed plates. A movable seat is threadedly connected to the threaded rod. A cleaning rod is movably installed on the movable seat. A limiting rod passes through the lower end of the movable seat.

[0026] like Figure 1-6 As shown, a single-sided embossing and laminating device for producing household paper includes a processing table 1. Two symmetrically arranged first fixing plates 2 are fixedly installed on one end of the upper surface of the processing table 1. Two sets of conveying rollers 4 are arranged between the two first fixing plates 2. Two symmetrically arranged third fixing plates 7 are fixedly installed on the other end. Back pressure rollers 6 are rotatably installed on the upper ends of the two third fixing plates 7. Second fixing plates 3 are fixedly installed on both sides of the outer wall of the processing table 1, located outside the third fixing plates 7. A detachable embossing roller 5 is movably installed on the upper end of the two second fixing plates 3. A cleaning component for cleaning the surface of the embossing roller 5 is also provided between the upper halves of the second fixing plates 3. The cleaning component includes a threaded rod 14 with both ends rotatably connected to the two second fixing plates 3. A movable seat 16 is threadedly connected to the threaded rod 14. A cleaning rod 17 is movably installed on the movable seat 16. A limiting rod 15 passes through the lower end of the movable seat 16. The two ends of the limiting rod 15 are fixedly connected to the inner walls of the upper halves of the two second fixing plates 3 respectively.

[0027] The tissue paper to be embossed is conveyed by two conveyor rollers 4. The end of the tissue paper roll passes between the embossing roller 5 and the back pressure roller 6 and is embossed by the embossing roller 5. The embossing roller 5 is a steel pressure roller and the back pressure roller 6 is an elastic pressure roller. The embossing roller 5 can emboss on one side of the tissue paper roll. When the embossing roller 5 is in use, the paper scraps attached to the outer wall of the embossing roller 5 can be cleaned by the cleaning component. The threaded rod 14 is threadedly connected to the movable seat 16. The lower end of the movable seat 16 is slidably connected to the limiting rod 15. When the threaded rod 14 rotates, the movable seat 16 can move along the threaded rod 14 and the limiting rod 15 under the action of the threaded transmission. The upper end of the movable seat 16 is movably connected to the cleaning rod 17. The bottom surface of the end of the cleaning rod 17 is provided with a cleaning soft brush. The cleaning rod 17 moves back and forth on the outer wall of the embossing roller 5 to clean the paper scraps attached to the outer wall of the embossing roller 5 and prevent the paper scraps from clogging the pattern on the embossing roller 5.

[0028] like Figure 2 As shown, the upper half of the two second fixing plates 3 are provided with mounting grooves 8 corresponding to the two ends of the embossing roller 5. The mounting block 10 is slidably installed inside the mounting groove 8, and the end of the embossing roller 5 is movably connected to the mounting block 10. When the mounting block 10 slides upward and separates from the inside of the mounting groove 8, it is convenient for the user to disassemble and replace the embossing roller 5.

[0029] like Figure 3 As shown, a connecting groove 19 is provided through the mounting block 10. A clamping block 20 is rotatably installed inside the connecting groove 19. Bearings 21 are rotatably installed at both ends of the embossing roller 5, and the bearings 21 are clamped inside the connecting groove 19. Bearings 21 are provided at both ends of the embossing roller 5. The inner ring of the bearing 21 is fixedly connected to the outer wall of the end of the embossing roller 5. When the bearing 21 is installed inside the connecting groove 19, the clamping block 20 inside the connecting groove 19 is rotated to a vertical position. At this time, the clamping block 20 can squeeze the outer wall of the bearing 21. When the mounting block 10 moves back to the inside of the mounting groove 8, the inner wall of the mounting groove 8 can continuously squeeze the part of the outwardly protruding clamping block 20 to ensure the clamping effect of the clamping block 20 on the bearing 21.

[0030] like Figure 2 As shown, lifting blocks 11 are fixedly installed on the upper surfaces of the two second fixed plates 3. A first electric telescopic rod 12 is fixedly installed on the lifting block 11. The output end of the first electric telescopic rod 12 is fixedly connected to the upper surface of the mounting block 10. The mounting block 10 can be automatically moved out of the mounting groove 8 by the two first electric telescopic rods 12, which makes it easier for the user to separate the two ends of the embossing roller 5 from the mounting block 10.

[0031] like Figure 2As shown, the cleaning assembly also includes two fourth fixing plates 18 fixedly mounted on the upper surface of the movable seat 16. The cleaning rod 17 is located between the two fourth fixing plates 18, and the outer wall of the cleaning rod 17 is rotatably connected to the two fourth fixing plates 18. A second electric telescopic rod 22 is fixedly mounted on the outer wall of the movable seat 16 away from the embossing roller 5. The upper end of the second electric telescopic rod 22 is slidably connected to the end of the cleaning rod 17 away from the embossing roller 5. A groove 23 is opened at the end of the cleaning rod 17 connected to the second electric telescopic rod 22. A round rod is fixedly connected to the upper end of the second electric telescopic rod 22, and the round rod is slidably arranged inside the groove 23. When the telescopic end of the second electric telescopic rod 22 drives the end of the cleaning rod 17 to move towards the embossing roller 5, the cleaning rod 17 is rotatably connected to the cleaning rod 17. When the cleaning rod 17 is in operation, it rotates around the connection point with the fourth fixed plate 18, causing the end of the cleaning rod 17 above the embossing roller 5 to tilt upwards. This allows the embossing roller 5 to be moved upwards between the two mounting blocks 10, making it easier to replace the embossing roller 5 after it wears out. After the embossing roller 5 is replaced, the output end of the second electric telescopic rod 22 moves upwards again, allowing the end of the cleaning rod 17 with the cleaning brush to rotate back to a horizontal position. When not in use, the cleaning rod 17 is located at both ends of the embossing roller 5 and does not contact the outer wall of the embossing roller 5. When in use, it can clean the paper scraps attached to the outer wall of the embossing roller 5 during the sliding process.

[0032] like Figure 4 As shown, a first servo motor 13 is fixedly installed on the outer wall of one of the second fixing plates 3 at a position corresponding to the threaded rod 14, and the output end of the first servo motor 13 is fixedly connected to the end of the threaded rod 14; the threaded rod 14 is driven to rotate by the first servo motor 13, and then the movable seat 16 is driven to move by the thread transmission between the threaded rod 14 and the movable seat 16.

[0033] like Figure 2 As shown, a reset spring 9 is fixedly connected inside the mounting groove 8 below the mounting block 10. The upper end of the reset spring 9 is fixedly connected to the bottom surface of the mounting block 10. The reset spring 9 can be connected between the mounting block 10 and the inner wall of the mounting groove 8 to prevent the mounting block 10 from completely detaching from the inside of the mounting groove 8.

[0034] The working principle of this utility model is as follows: During use, the tissue paper to be embossed is conveyed by two conveying rollers 4. The end of the tissue paper roll passes between the embossing roller 5 and the back pressure roller 6, where the embossing roller 5 is a steel pressure roller and the back pressure roller 6 is an elastic pressure roller. The embossing roller 5 can emboss one side of the tissue paper roll. During use, the cleaning component can clean the paper scraps attached to the outer wall of the embossing roller 5. The first servo motor 13 drives the threaded rod 14 to rotate. The threaded rod 14 is threadedly connected to the movable seat 16. The lower end of the movable seat 16 is slidably connected to the limiting rod 15. The movable seat 16 can move along the threaded rod 14 and the limiting rod 15. The upper end of the movable seat 16 is movably connected to the cleaning rod 17. The bottom surface of the end of the cleaning rod 17 is provided with a cleaning soft brush. By moving the cleaning rod 17 back and forth on the outer wall of the embossing roller 5, the paper scraps attached to the outer wall of the embossing roller 5 can be cleaned, preventing the paper scraps from clogging the pattern on the embossing roller 5. When the pattern on the surface of the embossing roller 5 becomes worn and unclear due to long-term use, the mounting block 10 can be removed upward from the inside of the mounting groove 8 by the two first electric telescopic rods 12. After both mounting blocks 10 are removed from the inside of the mounting groove 8, the two ends are connected to the mounting plate. The embossing roller 5 connected to mounting block 10 can be removed after disassembly. One of the mounting blocks 10 has a second servo motor 24 on its outer wall that drives the embossing roller 5 to rotate. A rectangular groove is formed between the output end of the second servo motor 24 and the end of the embossing roller 5. A rectangular block is fixedly mounted on the output end of the second servo motor 24, and the rectangular block is snapped into the inside of the rectangular groove. The connection between the rectangular groove and the rectangular block can be detached by sliding. Therefore, after the end of the embossing roller 5 is separated from the output end of the second servo motor 24, the embossing roller 5 can be disassembled and replaced. The replaced embossing roller 5 is then snapped into the mounting block 10 at both ends. Inside the docking groove 19 opened on the top, the embossing roller 5 is then pushed horizontally so that the rectangular block fixedly installed at the output end of the second servo motor 24 can be re-clamped into the rectangular groove opened at the end of the embossing roller 5. Then, by rotating the clamping block 20, the clamping block 20 is squeezed tightly against the outer wall of the bearing 21. During the process of the mounting block 10 moving back into the mounting groove 8, the inner wall of the mounting groove 8 squeezes the clamping block 20, which can fully squeeze the outer wall of the bearing 21 under the action of the clamping block 20. When the mounting block 10 moves down to the initial position, the embossing roller 5 after replacement can be put back into use to ensure the embossing effect of the embossing roller 5 on the paper roll.
