Description
Technical Field
[0001] The utility model relates to the technical field of printing, in particular to a paper feeding device of a full-automatic printing machine. Background Art
[0002] A printing press is a machine for printing text and images. A modern printing press is generally composed of mechanisms such as plate mounting, inking, embossing, and paper feeding (including folding). Its principle is to first make a printing plate with the text or image to be printed, mount it on the printing press, then apply ink to the place where the text and image are on the printing plate manually or by the printing press, and then directly or indirectly transfer it to paper or other substrates (such as textiles, metal plates). A Chinese patent announcement number CN 220563846U discloses a paper feeding mechanism for a printing press, which relates to the technical field of printing equipment and includes a bottom plate, an inclined plate is installed in the middle of the top of the bottom plate, two supporting columns are installed on both sides of one end of the top of the bottom plate, a placing plate is installed on the top of the four supporting columns, a paper feeding device is arranged at the bottom of the placing plate, fixed columns are installed on both sides of the top of the inclined plate, lifting grooves are opened on both sides of the opposite surfaces of the two fixed columns, and pressure lifting sensors are arranged at the bottom of the inner cavities of the two lifting grooves.
