Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, and more specifically to a clip-type water-ink 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 loading, inking, embossing, and paper feeding (including folding). Its principle is to first make the text or image to be printed into a printing plate, which is then manually installed on the printing plate roller of the printing press and then installed on the printing press. When the machine is running, the ink transfer mechanism transfers the color to the printing plate, and then directly or indirectly transfers it to paper or other substrates (such as textiles, metal plates).

[0003] Most of the existing water-based ink printing machines are multi-color printing machines, with each color occupying a color group. In actual use, the paper is fed through the paper feeding unit and then printed through the printing unit. After printing, the machine must be shut down and leave the production area to make preparations for the next round. After preparation, it needs to be moved back to the production area for printing. During this process, it takes a certain amount of time to wait, which is troublesome and affects work efficiency to a certain extent, making it inconvenient to use. Therefore, there is an urgent need to improve the technology of the structure of water-based ink printing machines to improve this equipment. Utility Model Content
