[0002] In the book printing process, the guide roller is a key component for paper transport, and its operating accuracy directly affects the printing quality.

[0003] Traditional book printing guide rollers are prone to paper misalignment during prolonged use or high-speed operation, leading to problems such as misaligned printed patterns and inaccurate registration. This seriously affects the yield and aesthetics of the books and has a certain adverse impact on the book printing process. In order to overcome the shortcomings of existing technologies, we propose an anti-misalignment book printing guide roller. Utility Model Content

Rotation interfaces are provided at both ends of the connecting rods 18 between the upper ends of the third sliders 22 and the side wall of the connector 17, respectively. 18 can rotate between the third slider 22 and the side wall of the connector 17. When the connector 17 is driven up and down by the second electric actuator 16, the connecting rod 18 will drive the third slider 22 to slide in the middle of the sliding groove 19. The lower end of each of the two sets of third sliders 22 is provided with a set of movable rods 20, and the lower end of each of the two sets of movable rods 20 is provided with a set of correction plates 21. The movable rods 20 are used to connect the correction plates 21 to the third slider 22, and the correction plates 21 are used to correct the paper.

[0022] like Figures 1-4As shown, a set of first sliders 12 are respectively installed between the two ends of the two sets of lifting guide rails 3 and the inner wall of a set of column guide rails 2.

The first electric push rod 6 pushes the two sets of lifting guide rails 3 downward through the connecting frame 4, so that the moving rod 7 and the lower printing roller 15 move downward and come into contact with the paper. The second electric push rod 16 extends and retracts, causing the connecting head 17 to move up and down. The connecting head 17 then drives the two sets of third sliders 22 to slide in the middle of the two sets of sliding grooves 19 through the connecting rods 18 on both sides. The third slider 22 then drives the two sets of correction plates 21 to move through the moving rod 20. The correction plates 21 adapt to the width of the paper and come into contact with the two sides of the paper. The motor 11 starts and drives the lead screw 9 to rotate. The moving rod 7 then moves between the outer wall of the lead screw 9 and the two sets of lifting guide rails 3, so that the printing roller 15 rolls on the paper. At the same time, the correction plates 21 move with the printing roller 15 to prevent the paper from being misaligned during the printing process.
