[0003] An existing multi-layer napkin embossing device mainly consists of a support frame, a conveying mechanism, and an embossing mechanism. The support frame provides support and fixation, while the conveying mechanism includes a motor, a conveyor belt, and multiple sets of rollers. The motor drives the conveyor belt to move smoothly and can transport the napkin base paper.

[0004] Traditional embossing devices typically use fixed embossing rollers. Changing patterns or cleaning the roller surface requires disassembling the bearings and transmission structure, which is time-consuming and requires specialized tools, resulting in low production changeover efficiency. Furthermore, untimely cleaning of the rollers can lead to pattern blockage, causing quality problems such as missing or blurred patterns, resulting in a high scrap rate. In addition, the spacing of traditional napkin embossing devices is mostly fixed, which cannot adapt to the pressing needs of different sizes of napkins. When adjusting the spacing, it often relies on manual operation, and uneven force can easily cause the rollers to tilt. Therefore, a multi-layer napkin embossing device is proposed to solve the above problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5This utility model provides an embodiment of a multi-layer napkin embossing device, including a workbench 1. The workbench 1 facilitates the operation of the equipment. Two baffles 1 6 and 26 are fixedly connected to the top of the workbench 1. A placement roller 7 and a take-up roller 8 are installed between the two baffles 1 6 and 26. The placement roller 7 and the take-up roller 8 are fixed by the baffles 1 6 and 26. The placement roller 7 is used to place napkins, and the take-up roller 8 is used to collect the embossed napkins. An adjustment component is installed on the top of the workbench 1. Two embossing rollers 9 are installed inside the adjustment component. The distance between the embossing rollers 9 is adjusted by the adjustment component. First, the napkins can be placed on the placement roller 7, and then the napkins can be transferred to the take-up roller 8 through the embossing rollers 9. At this time, the external drive source is started, and the drive source drives the take-up roller 8. Then the take-up roller 8 can collect the embossed napkins.

[0035] The adjustment assembly includes a motor 24, which is fixedly connected to the bottom of the worktable 1. A gear 22 is fixedly connected to the output end of the motor 24. A slide plate 18 is mounted on the top of the worktable 1. Two stops 10 are slidably connected to the outer side of the slide plate 18, providing a movement path for the stops 10. Two embossing rollers 9 are installed between the two stops 10, which fix the embossing rollers 9 in place. A rack 17 and a rack 2 19 are fixedly connected to the bottom of the two stops 10, respectively. The gear 22 meshes with the rack 17 and rack 2 19. A notch 21 is provided at the bottom of each of the two stops 10. A groove 20 is provided on the outer side of the slide plate 18. The groove 20 serves as a sliding guide structure and is provided on the slide plate 18 to guide the stop block 10 to slide along a fixed trajectory, ensuring that the two stop blocks 10 move synchronously and smoothly, preventing the embossing roller 9 from deviating, and ensuring the embossing quality. The stop block 10 is slidably connected to the outer side of the groove 20. By starting the motor 24, the motor 24 drives the gear 22. At this time, the gear 22 will control the rack 17 and rack 29 to move in opposite directions. When the rack 17 and rack 29 move in opposite directions, the rack 17 and rack 29 can pass through the notch 21, thereby controlling the distance between the two stop blocks 10 to be closer.

[0036] Reference Figure 2A housing 14 is fixedly connected to the outer side of the stop 10. The housing 14 protects the internal components and prevents them from shifting during operation. A rod 11 is slidably connected inside the housing 14. Slots 16 are provided inside both embossing rollers 9. The rod 11 interlocks with the slots 16, making the connection between the embossing rollers 9 and the stop 10 more secure. A spring 13 is fitted around the outer periphery of the rod 11. The spring 13 allows the rod 11 to return to its original position during operation. A retaining ring 25 is fixedly connected to the outer periphery of the insert rod 11. The retaining ring 25 is used to prevent the insert rod 11 from detaching from the outer casing 14 during operation. A retaining ring 15 is fixedly connected to the outer periphery of the insert rod 11. The retaining ring 15 abuts against the embossing roller 9. The retaining ring 15 is used to prevent the embossing roller 9 from sticking to the stop block 10, thereby avoiding the embossing roller 9 from getting stuck during operation. A pull ring 12 is installed at the end of the insert rod 11. The pull ring 12 is used to control the insert rod 11. By pulling the pull ring 12, the pull ring 12 drives the insert rod 11, causing the insert rod 11 to disengage from the slot 16, thereby making it easier and faster to remove the embossing roller 9.

[0037] Reference Figure 1 and Figure 4 The second baffle 26 is rotatably connected to the fence 4 via the hinge 3. The fence 4 can be opened via the hinge 3 to facilitate maintenance of the internal embossing roller 9 and to facilitate the removal of the embossing roller 9. The outside of the fence 4 is fixedly connected to the handle 5, which controls the opening and closing of the fence 4. The hinge 3 is used to connect the second baffle 26 and the fence 4. The bottom of the workbench 1 is fixedly connected to the protective shell 23, and the motor 24 is located inside the protective shell 23. The protective shell 23 is used to protect the internal motor 24. The bottom of the workbench 1 is fixedly connected to the support leg 2, which is used to support the workbench 1 and provide a stable working environment for the workbench 1.

[0038] Working principle: First, place the napkin to be printed on the placement roller 7, then transfer the napkin to the embossing rollers 9, and finally take the pressed napkin away with the take-up roller 8. When you want to change the pattern on the embossing roller 9 or clean the embossing roller 9, pull the pull ring 12. The pull ring 12 will drive the insertion rod 11 to move, so that the insertion rod 11 disengages from the slot 16 on the embossing roller 9. At this time, the embossing roller 9 can be removed to change its shape or clean it at any time. When you need to assemble the embossing roller 9, first insert one end of the embossing roller 9 into the stop block 10, and then align the slot 16 of the other end of the embossing roller 9 with the insertion rod 11. Then release the pull ring 12. The insertion rod 11 will be pushed back into the slot 16 by the elastic force of the spring 13, thereby fixing the embossing roller 9 and the stop block 10.

[0039] When you want to adjust the spacing of the embossing rollers 9 to press napkins of different sizes, first remove the embossing rollers 9, then start the motor 24. The motor 24 will drive the gear 22 to rotate. The rotation of the gear 22 will control the rack 17 and rack 29 to move in opposite directions. The rack 17 and rack 29 will drive the two stops 10 to slide outside the groove 20 on the slide plate 18, thereby adjusting the distance between the two stops 10. Then, install the embossing rollers 9 of the corresponding size between the two stops 10. This not only solves the problem of pressing napkins of different sizes, but also avoids misalignment of the embossing pattern and uneven edges caused by roller offset. It ensures that the pattern of each part of the napkin is aligned and consistent, meets the appearance standards, and reduces defective products.
