Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0023] Embodiment one

[0024] In this embodiment, the two-color embossing printing machine includes a machine body 1 and a machine frame 2. The machine body 1 is provided with two symmetrical paper feeding channels, the right side is provided with the machine frame 2, and the paper discharging guide frame 3 is installed on the machine frame 2. The whole machine structure is arranged left and right, and symmetrically distributed up and down, which ensures the coordinated operation of each processing module and improves the uniformity and stability of the printing and embossing effect.

[0025] According to the design proportion of the machine body 1, the machine body 1 is divided into upper and lower two paper feeding channels from top to bottom. Each paper feeding channel is provided with the following components:

[0026] Embossing flat roller 4: plays a key role in the paper feeding channel, used to uniformly feed the paper into the subsequent stations;

[0027] Embossing pattern roller 5: arranged on one side of the bottom of the embossing flat roller 4, and a pressure oil cylinder is arranged at the bottom of the embossing pattern roller 5. By adjusting the pressure oil cylinder 6, the appropriate channel spacing between the embossing pattern roller 5 and the embossing flat roller 4 is formed to adapt to paper of different thickness and material. After the paper passes through the embossing flat roller 4 and the embossing pattern roller 5, the paper changes from multiple layers to one, and the corresponding pattern is transferred according to the shape of the pattern roller;

[0028] Two sets of printing mechanisms: respectively arranged on both sides of the embossing flat roller, which are the first color printing mechanism 7 and the second color printing mechanism 8. A hydraulic front pushing device is arranged on the side of each of the first color printing mechanism 7 and the second color printing mechanism 8, which pushes the embossing flat roller 4. The color printing mechanism is installed on the slide rail 10, and the channel spacing between the color printing mechanism and the embossing flat roller 4 is adjusted in real time by the hydraulic front pushing device 11. In addition, the slide rail 10 is also provided with a pin locking device 12 to ensure the stable positioning of the color printing mechanism during processing after adjustment.

[0029] A plurality of guide wheels are arranged on the paper feeding channel, which are respectively located at the paper feeding end, near the embossing flat roller 4, and between the color printing mechanism and the paper outlet guide frame 3. The arrangement of these guide wheels is used to adjust the paper feeding direction, ensure the paper to be flat and accurately positioned when passing through each station, and prevent the printing quality problem caused by paper deviation.

[0030] Paper conveying and processing flow:

[0031] Paper feeding stage, at the paper feeding end, a paper feeding guide wheel 13 is arranged, which is used to correctly feed the original paper into the area between the embossing flat roller and the first color printing mechanism 7. This design ensures that the paper is always in the best positioning state, thereby realizing high-speed and continuous printing processing.

[0032] First color printing stage, first enter the processing area of the first color printing mechanism 7, which is provided with a hydraulic front pushing device. By adjusting the mechanism, the channel between the color printing mechanism and the embossing flat roller is always accurately matched, ensuring the clear and consistent color printing effect.

[0033] Embossing stage, the paper enters under the action of the embossing flat roller 4, and the paper gradually enters the working channel between the embossing pattern roller 5 at the bottom of the flat roller and the flat roller driven by the flat roller. During this process, the pressure oil cylinder adjusts the gap between the embossing pattern roller 5 and the flat roller according to the characteristics of the paper, ensuring that the embossing effect is uniform and the depth is appropriate.

[0034] The second color printing stage, after the embossing stage, the paper is guided along the channel to the second color printing mechanism 8, and the paper guide wheel 14 is arranged above the second color printing mechanism 8, which further adjusts the paper and reliably sends the finished paper out of the machine table. Finally, it is guided out of the frame by the paper guide frame 3.

[0035] Hydraulic front push adjustment mechanism: The color printing mechanism is installed on the slide rail 10, and the working distance between the color printing mechanism and the embossing flat roller is adjusted in real time through the hydraulic front push device, so that the color printing depth and precision can be flexibly adjusted. The stability of the hydraulic device ensures that the color printing mechanism can quickly respond and always maintain the best working state during high-speed printing.

[0036] Pin locking device: In order to prevent the color printing mechanism from changing position due to vibration or external disturbance during equipment operation, the slide rail 10 is provided with a pin locking device. Once the color printing mechanism reaches the ideal state through adjustment, it can be fixed through the device, thereby maintaining long-term stable printing quality.

[0037] In this embodiment, the symmetrical layout of the two groups of paper feeding channels, the guide wheels, and the coordinated cooperation between the embossing and color printing mechanisms not only realize accurate control of the paper, but also ensure the consistency of the printing and embossing quality through hydraulic adjustment and locking devices. Modular design allows each functional component to be independently maintained and replaced, and also provides a hardware foundation for the future introduction of automatic detection and intelligent control systems, thereby improving the production efficiency and product quality of the equipment as a whole.
