[0002] Kitchen paper is an indispensable item in daily life and is widely used in many occasions such as cleaning, absorbing oil, and wrapping food. It is characterized by strong water absorption, softness and not easy to break. Embossing technology can not only improve the aesthetics of kitchen paper, but also enhance the water absorption and softness of paper. By pressing different patterns on the paper surface, it not only makes the product more personalized, but also increases the surface area of ​​the paper through the tiny bumps and grooves of the pattern, thereby improving water absorption. In addition, embossing can also increase the layering and feel of the paper, improving the user experience.

[0003] Currently, most kitchen paper embossing equipment on the market uses fixed embossing rollers. This design requires manual adjustment of the height of the embossing roller. This operation is not only inefficient, but also has limited accuracy, resulting in unstable embossing quality. Especially when processing kitchen paper of different thicknesses or different materials, the fixed height embossing roller is difficult to adapt, affecting the final quality of the product. In addition, manual adjustment of the embossing roller height may cause production line shutdown, increasing production costs and time loss.

[0025] Specifically, Figure 1 and Figure 2 As shown, when the height of the embossing roller 5 is adjusted, a command is issued to the cylinder 12 through the external control system, and the cylinder 12 drives the piston rod to extend or retract. The shaft sleeve 8 is accurately controlled by the air intake to pull the bearing seat 6 up and down in the adjustment groove 7, thereby driving the entire embossing roller 5 to adjust the distance with the supporting roller 4, so as to adjust the height of the embossing roller 5. Different pressures are provided for kitchen paper of different thicknesses and sizes, which is more convenient for the entry and exit of paper and ensures the embossing quality.

[0026] Embodiment 2: One group of the outer parts of the bearing seat 6 is movably sleeved with a fixed seat 10, and a dial 9 is movably assembled at the fixed seat 10. A driving motor 11 is installed at the rear end of the dial 9. A lever 22 is fixedly sleeved at the center of the dial 9. A triangular plate 23 is fixedly sleeved at one end of the adjustment slot 7. A dial slot 21 is provided in the triangular plate 23. The lever 22 matches the size of the dial slot 21. The triangular plate 23 is a triangular component with three concave arcs. The concave arc surface of the triangular plate 23 matches the dial 9.

[0030] Working principle: The paper is transmitted from the first shaft frame 3 and transmitted to the space between the supporting roller 4 and the embossing roller 5 through an external driving force. When the height of the embossing roller 5 is adjusted, an instruction is issued to the cylinder 12 through an external control system. The cylinder 12 drives the piston rod to extend or retract. The shaft sleeve 8 is precisely controlled by the air intake to pull the bearing seat 6 up and down in the adjustment groove 7, thereby driving the entire embossing roller 5 to adjust the distance with the supporting roller 4, so as to adjust the height of the embossing roller 5 and provide different pressures for kitchen paper of different thicknesses and sizes. The embossing roller 5 abandons the traditional direct motor connection method and drives the dial 9 to rotate through the driving motor 11, driving the lever 22 at its center position to swing. When the lever 22 swings into the lever groove 21, the triangular plate 23 is driven to rotate one-third under the action of the circle, and the embossing roller 5 is rotated 60°.
