Description

Technical Field

[0001] This invention relates to offset printing machinery, and more particularly to a skew adjustment mechanism for a printing plate cylinder and a printing plate cylinder assembly thereof. Background Technology

[0002] Before starting printing, the offset printing press first creates a PS (photocopy plate) of the printed content. Then, the PS plate is securely mounted on the printing cylinder, ensuring there are no gaps between it and the cylinder's outer surface. The plate clamping device on the printing cylinder is specifically designed for clamping the PS plate, and it has functions for clamping, tightening, and adjusting the PS plate. After the PS plate is clamped by the plate clamping device, it needs to be tightened, and then the registration accuracy between color groups is adjusted.

[0003] During the printing process, the printed pattern should be aligned with the theoretical position on the paper. However, due to various factors such as parts and assembly in different printing units of the printing press, the actual position of the pattern on the printed material may deviate from the theoretical requirement. This means that lateral deviations in the printed material require axial adjustments, and skew deviations require skew adjustments. In multi-color printing, the positions of the patterns printed in each printing unit on the printed material must be consistent. This necessitates that the printing cylinder possess corresponding adjustment functions, allowing the axis of the printing cylinder to move laterally left and right and / or tilt to adjust the lateral position and skew of the printing plate.

[0004] The State Intellectual Property Office of the People's Republic of China has published a utility model patent entitled "An Electric Adjustment Device for Printing Plate Cylinder Tilting," with authorization announcement number CN216804832U and authorization announcement date of June 24, 2022. Specifically, it discloses an electric adjustment device for printing plate cylinder tilting, installed on the operating side wall of a printing press and including an eccentric sleeve and an adjustment mechanism connected to the eccentric sleeve. The eccentric sleeve is fitted onto the shaft at one end of the operating side of the printing plate cylinder and is disposed within a through hole in the operating side wall of the printing press. The adjustment mechanism includes a fixed block, a servo motor, a lead screw, and a slider. The fixed block is installed on the outer end face of the eccentric sleeve. The servo motor is installed on the outer side face of the operating side wall of the printing press via a motor mounting bracket. The lead screw is connected to the shaft of the servo motor. The slider is threadedly connected to the lead screw and is connected to the outer end face of the fixed block via a pin. Because the slider is connected to the lead screw by a thread, the slider can only move a distance of one screw pitch after the lead screw is rotated one revolution. The adjustment speed is extremely slow and cannot meet the requirements of rapid adjustment, resulting in a great waste of paper.

[0005] The State Intellectual Property Office of the People's Republic of China has published a utility model patent entitled "Quick Clamping Device for PS Plates on Printing Plate Cylinders," with authorization announcement number CN201597243U and authorization announcement date of October 6, 2010. Specifically, it discloses a quick clamping device for PS plates on printing plate cylinders, including a gripper-side plate clamp and a trailing-side plate clamp, a gripper-side plate clamping base, a trailing-side plate clamping platform, a trailing-side pad, a tensioning shaft, a gripper-side locking shaft, and a trailing-side lock. The printing plate cylinder has a plate shaft, with the gripper side plate clamping reference platform located on the bottom surface of the axial groove and movably connected to the gripper side plate clamp; the trailing side plate clamping platform is located at the inner end of the trailing side plate clamp and movably connected to the trailing side plate clamp; the PS plate covers the outer surface of the printing plate cylinder, with its gripper edge inserted between the inner end face of the gripper side plate clamp and the outer end face of the gripper side plate clamping reference platform, and its tail edge inserted between the inner end face of the trailing side plate clamp and the outer end face of the trailing side plate clamping platform. Because the quick-clamping device for the PS plate on this printing plate cylinder can only be used for manual installation and removal of the PS plate, it is impossible to further improve the efficiency of PS plate installation and removal, the installation accuracy of the PS plate, or the labor intensity of employees.

[0006] The State Intellectual Property Office of the People's Republic of China has published a utility model patent entitled "An Axial Adjustment Mechanism for a Printing Roller," with authorization announcement number CN217226972U and authorization announcement date of August 19, 2022. The patent discloses the following technical solution: a mounting frame and a transmission shaft. An adjusting rod is mounted on the mounting frame. A movable plate is rotatably connected to one end of the front of the adjusting rod. Moving racks are fixedly connected to both sides of the back of the movable plate. Arc-shaped sleeves are fitted onto the moving racks, and gears are provided on the sides of the moving racks. A rotating shaft is mounted on the gears, and an adjusting component is provided at the bottom end of the rotating shaft. A connecting component is movably connected to one end of the transmission shaft, and the connecting component is movably connected to the adjusting component. Because the change in the rotation angle of the adjusting rod and the change in the axial displacement of the transmission shaft cannot form a linear relationship, it is not easy to accurately adjust the axial position of the printing roller. Summary of the Invention
