[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate mounting, inking, embossing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate, which is then mounted on a printing press. Then, ink is applied to the places on the printing plate where the text and image are, either manually or by a printing press, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass, and ceramics), thereby replicating a printed product identical to the printing plate.

[0003] The rubber roller is one of the indispensable equipment in the printing process. It can transfer ink from the ink cartridge or ink fountain to the printing plate evenly to ensure that the printed products have clear lines and bright colors. For different printing situations and after a certain period of use, the printing rubber roller needs to be replaced. However, the rubber roller is generally installed in a rotating manner inside the printing machine, which is time-consuming and labor-intensive to disassemble and assemble, increasing the labor intensity of replacement and reducing the convenience of replacing the rubber roller.
