Description

Technical Field

[0001] This utility model relates to the field of protective device technology, specifically a protective device for a printing press. Background Technology

[0002] A printing press is a machine that processes and finishes cut paper by printing. During the printing process, protective devices need to be installed on the side of the printing press to prevent ink, ink oil or pigment from splashing out.

[0003] To facilitate the installation and removal of protective plates for printing presses, existing technologies have made numerous improvements to protective devices for printing presses. For example, patent publication number CN221022862U discloses a protective device for printing presses, including a printing press body. Side plates are symmetrically welded to the upper surface of the printing press body. A support frame is rotatably mounted on the upper surface of the side plates via a rotating shaft. Grooves are symmetrically formed on both sides of the support frame. A fixing tube is fixedly connected to the middle of one end of the inner wall of the groove. A movable rod is movably installed in the middle of the middle of one end of the fixing tube. A limit block is welded to the middle of one end of the movable rod. A spring is sleeved on one side of the outer surface of the movable rod. A protective plate is installed in the middle of one end of the support frame. A limiting component is also provided on the outer surface of the protective plate. This application uses the limiting block to limit and fix the protective plate, thereby achieving the effect of convenient installation and removal of the protective plate, improving the overall stability of the protective plate during installation, solving the problem of possible tilting of the protective plate during installation, and improving the overall efficiency of the protective plate.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:
