Technical Field

[0001] This utility model belongs to the field of printing equipment technology, and specifically discloses a movable inking roller device for a rotary book printing press. Background Technology

[0002] In rotary book printing presses, the main function of the inking roller during the printing process is to evenly transfer ink to the image area of ​​the printing plate cylinder. In traditional designs, the axial position of the inking roller is strictly limited, preventing it from moving freely. Therefore, during the ink transfer process from the inking roller to the printing plate cylinder, factors such as roller pressure, cylinder impact, and the effect of temperature on ink flow can cause uneven ink transfer to the printing plate cylinder, potentially resulting in a "ghosting" effect on the printed product. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a movable inking roller device for a rotary book printing press.
