[0015] Refer to Figures 1 - 4, an anti-offset self-correcting offset printing machine for paper packaging boxes, including a main frame body 1, a reaction module 2 is arranged on the inner wall of the main frame body 1, and a lower pressing roller 5 is movably connected to the main frame body 1. A driving motor 3 is fixedly connected to the outer wall of one side of the main frame body 1, and the output end of the driving motor 3 is fixedly connected to one end of the lower pressing roller 5. The reaction module 2 includes a floating frame 204. Two symmetrically arranged mounting seats 205 are fixedly connected to the top of the floating frame 204. Circular holes are opened on both mounting seats 205. The same movable roller 206 is rotatably connected in the two circular holes through bearings. The reaction module 2 further includes a fixed frame 201. The fixed frame 201 is connected to the inner wall of the main frame body 1 by bolts. Two limiting rods 202 are fixedly connected to the top of the fixed frame 201. The floating frame 204 slides on the outer walls of the two limiting rods 202, and springs 203 are wound around the outer parts of the two limiting rods 202. One end of each of the two springs 203 is fixedly connected to the top of the fixed frame 201, and the other end is fixedly connected to the floating frame 204. Two mounting grooves are opened on the movable roller 206. Arc-shaped rods 211 are fixedly connected in the two mounting grooves. Sliding members 207 are slidably connected to the outer parts of the two arc-shaped rods 211, and springs 212 are wound around the outer parts of the two arc-shaped rods 211. One end of each of the two springs 212 is fixedly connected to the movable roller 206, and the other end is fixedly connected to the corresponding sliding member 207. The outer walls of the two sliding members 207 are fixedly connected to the same movable cylinder member 208. Two symmetrically arranged mounting frames 209 are fixedly connected to the top of the floating frame 204. Movable holes are opened on both mounting frames 209. Movable sliding rods 210 are rotatably connected in the two movable holes through bearings, and the ends of the two movable sliding rods 210 far away from the mounting frames 209 are movably connected to the corresponding mounting seats 205. Mounting holes are opened on both mounting frames 209, and electric telescopic rods 213 are fixedly connected in the two mounting holes. The driving ends of the two electric telescopic rods 213 are fixedly connected to sliding frames 214. The two sliding frames 214 slide on the outer walls of the corresponding movable sliding rods 210. Two symmetrically arranged flexible movable wheels 215 are movably connected to the two sliding frames 214. An upper pressing roller 4 is movably connected to the main frame body 1, and gears 7 are fixedly connected to the outer parts of the upper pressing roller 4 and the lower pressing roller 5.

[0016] Working principle: Thread the paper tape through between the upper pressure roller 4 and the lower pressure roller 5. At this time, the paper tape slides outside the movable cylinder part 208. Start the driving motor 3 to rotate the lower pressure roller 5. Through the meshing of the first gear 7 and the second gear 8, the ink distribution roller 6 rotates to evenly apply the ink in the ink storage box 9 onto the lower pressure roller 5. The upper pressure roller 4 and the lower pressure roller 5 rotate towards each other to transport and print the paper tape simultaneously. When the paper tape generates abnormal tension during the transportation process on the reaction module 2, the movable roller 206 will drive the floating frame 204 to slide on the limiting rod 202 against the elastic action of the first spring 203, and buffer adjustment is carried out through the elastic action of the first spring 203. At the same time, under the traction of excessive friction, the movable cylinder part 208 drives the sliding part 207 to slide outside the arc-shaped rod 211 against the elastic action of the second spring 212, and a certain degree of offset is carried out through the elastic action of the second spring 212 to avoid inconvenient transportation and breakage caused by abnormal paper tape tension. When the paper tape slides outside the movable cylinder part 208 and the movable slide rod 210, due to factors such as the self-weight of the paper tape, the paper tape is adjusted towards the middle position through the guiding action of the angle between the movable slide rod 210 and the horizontal direction. Synchronously and reciprocally start the electric telescopic rods 213 on both sides. The electric telescopic rods 213 reciprocally push the sliding frame 214 to slide outside the movable slide rod 210. The flexible movable wheels 215 on both sides contact the edge of the paper tape to keep the paper tape in the middle position all the time.
