Description

Technical Field

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

[0002] Embossing of paper towels refers to the process of processing paper through specific techniques to create uneven patterns and designs on its surface. The purpose is to make the paper towel surface more aesthetically pleasing, increase product appeal, meet consumer aesthetic needs, change the feel of the paper towel, increase friction, and enhance the user experience. It can also improve the absorbency and oil-removing capacity of the paper towel. Applicable products include kitchen paper towels, facial tissues, and toilet paper. Embossing is a common paper towel processing technique that not only improves the product's appearance and functionality but also enhances the user experience. However, embossing paper towels requires specialized embossing equipment for large-scale processing.

[0003] A tissue embossing device is a mechanical device used to apply patterns and textures to the surface of tissues during the tissue production process. Its main components include an embossing roller made of rigid material with intricate patterns and textures engraved on its surface, a transmission mechanism that drives the roller's rotation, and an infeed / outfeed structure that smoothly feeds unembossed tissues into the device and ejects embossed tissues from it. Existing tissue embossing devices often switch between different embossing patterns by replacing the entire embossing roller or by using a modular design to replace specific pattern modules. However, individually disassembling and replacing pattern modules during production is time-consuming and labor-intensive, leading to reduced production efficiency and increased production costs. Furthermore, during the embossing process, the device cannot quickly adjust the pressure required for different tissue materials, making it prone to tearing due to excessive pressure, resulting in reduced product quality and increased production losses. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a paper towel embossing device, which aims to improve the problem that the existing technology of disassembling the embossing roller separately to replace the pattern module is time-consuming and laborious, resulting in reduced production efficiency and increased production costs.

A guide rod is slidably connected to the inner wall of the limit block. A pulling rod is fixedly connected to the top of the limit block.

A rotating shaft is rotatably connected to the inward side of the rotating rod. A rotating disk is rotatably connected to the bottom end of the rotating shaft. A rotating column is fixedly connected to the bottom end of the rotating disk. A worm gear is fixedly connected to the outer wall of the rotating column. A micro motor is fixedly connected to the top of the base near the edge. A worm is fixedly connected to the output end of the micro motor. The outer wall of the worm meshes with the outer wall of the worm gear.

[0008] As a further description of the above technical solution:

[0009] Multiple fixing blocks are fixedly connected to the bottom of the inner wall of the base, and a pressing rod is rotatably connected to the inner side of each fixing block.

[0010] The limiting block is rotatably connected to a second rotating shaft on its inward side. The outer wall of the second rotating shaft is provided with a sliding sleeve, and the inner wall of the sliding sleeve is slidably connected to the outer wall of the second rotating shaft.

[0011] As a further description of the above technical solution:

[0012] A controller is fixedly connected to the front side of the base, and the controller is electrically connected to the second asynchronous motor, the first asynchronous motor, and the micro motor respectively.

[0013] As a further description of the above technical solution:

[0014] A fixing rod is fixedly connected to the top of the inner wall of the base, and a scraper is fixedly connected to the outer wall of the fixing rod.

[0015] As a further description of the above technical solution:

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, by starting an asynchronous motor, the sun gear is driven to rotate, which in turn drives the planetary gear to rotate within the gear ring. This allows the embossing shaft to be rotated and adjusted to the desired option. At the same time, the fixing post can be inserted into the guide groove, and the clamping plate is attached to the edge of the actuating post. Then, the asynchronous motor is started to drive the actuating post to rotate, so that the embossing shaft can rotate together. This achieves the purpose of quickly switching between different embossing patterns, speeding up production efficiency and reducing production costs.

[0021] 2. In this utility model, by starting the guide groove, the worm gear is driven to rotate, which in turn drives the rotating disk to rotate. This causes the rotating shaft to pull the rotating rod, which in turn drives the pulling rod to slide along the guide groove. This, in turn, pulls the limiting block so that it can slide to the sides or the middle within the slide groove, thereby achieving the purpose of quickly adjusting the pulling of the paper towel, improving product quality, and reducing production losses.

[0041] Working principle: When different printing patterns need to be adjusted, firstly, the asynchronous motor 6 is started to drive the sun gear 12 to rotate, which in turn drives the planetary gear 11 to rotate on its own axis and revolve around the ring gear 7, thereby adjusting the position of different embossing shafts 10. At the same time, the asynchronous motor 13 is started to drive the actuating column 14 to rotate and adjust, so that while the previous embossing shaft 10 drives the fixed column 9 away from the guide groove 16, the next embossing shaft 10 can drive the fixed column 9 to be inserted into the guide groove 16, and the clamping plate 8 can be attached to the outer wall of the actuating column 14. Then, the asynchronous motor 13 is started to drive the actuating column 14 to rotate, which can drive the clamping plate 8 to drive the embossing shaft 10 to rotate, thus embossing the paper towel.

[0042] When embossing tissues of different sizes and lengths, the micro motor 209 is activated to drive the worm gear 213 to rotate, which in turn drives the rotating column 210 to rotate through the worm wheel 212, so that the rotating disk 211 can rotate together. This pulls the micro motors 209 on both sides, which can pull the rotating rod 207 to rotate, and then pull the pulling rod 205 to slide along the guide groove 202. Through the connecting rod 206, it drives multiple limiting blocks 204 to slide together, adjusting the distance between the rotating shaft 219 and the rotating shaft 219. At the same time, the guide rod 203 can provide secondary guidance for the sliding of the limiting blocks 204.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
