A printing substrate is arranged in the gap. In actual use, the ink in the ink fountain 9 is applied to the surface of the printing roller 8, and the driving motor 36 drives the printing roller 8 to rotate, thereby synchronously driving the printing roller 12 and the rubber roller 14 to rotate. The ink adhered to the printing roller 8 during the rotation of the printing roller 12 is transferred to the surface of the rubber roller 14, and then the ink on the rubber roller 14 is printed on the surface of the printing substrate when the printing substrate passes between the rubber roller 14 and the supporting roller 15, thereby completing the printing.

[0029] It should be noted that, as shown in Figure 1 and Figure 4 , two guide rollers 11 are rotatably connected between the two mounting plates 10. In actual use, as shown in Figure 4 , the printing substrate passes between the supporting roller 15 and the rubber roller 14 under the guidance of the guide rollers 11, thereby completing the printing.
