[0001] The utility model relates to the technical field of punching devices, in particular to a punching device for a printing machine. Background Art

[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. Then, the ink is 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. The invention and development of the printing press has played an important role in the spread of human civilization and culture.

[0003] A printing punch is a mechanical device that is mainly used in industries such as punching, binding, and printing. It includes the main body of the device, electronic control components, and other additional components. The performance of different brands and models of equipment is also different, but they can all punch holes of different sizes on paper to meet different needs.
