Printing plates 8 and other related printing components are installed at the top and bottom of the base frame 2. When the cylinder 14 drives the lifting plate 6 to rise and fall, the lifting plate 6 causes the first guide cylinder 5 to slide along the outer wall of the first guide rod 3, allowing the lifting plate 6 to smoothly lift and lower the printing plates 8. This allows the two printing plates 8 to contact the upper and lower surfaces of the paper for printing, achieving double-sided printing. Afterwards, the paper is spring-loaded... Spring 23 has good elasticity. When the printing plate 8 is raised and lowered to contact the paper for printing, if the pressure applied by the printing plate 8 to the paper is high, the lower connecting plate 20 will drive the limiting cylinder 24 to slide on the outer wall of the T-shaped rod 22, so that the spring 23 is in a contracted state, which can buffer the pressure applied by the printing plate 8 to the paper, thereby reducing the damage caused by the printing plate 8 to the printing paper. Finally, the electric push rod 7 drives the linkage plate 15 to move horizontally, so that the linkage plate 15 drives the second guide rod 17 to slide inside the second guide cylinder 16, so that the linkage plate 15 drives the printing plate 8 to move smoothly through the lower connecting plate 20 and other related components. This can adjust the distance between the printing plate 8 and the lifting plate 6, so that the printing plate 8 can print on paper of different sizes in a centered manner, thereby completing the use of the printing machine.
