Technical Field

[0001] The utility model belongs to the technical field of printing machines, in particular to a packaging box printing machine which is convenient for replacing printing patterns. Background Art

[0002] A printing press is a machine used to print text and images. It plays a vital role in the dissemination of human civilization and culture. It is generally composed of mechanisms such as plate setting, inking, pressing, and paper feeding (including folding). These mechanisms work together to transfer the text and images on the printing plate to paper or other substrates.

[0003] Existing printing machines usually use a single printing plate for transfer when in use. When different patterns need to be transferred, different printing plates need to be replaced, and the replacement efficiency is low. Therefore, a packaging box printing machine that is convenient for replacing printed patterns is proposed. Utility Model Content
