Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, and more particularly to an automatic feeding device for a printing machine. Background Art

[0002] A printing press is a machine that prints text and images. Modern printing presses generally consist of mechanisms such as plate mounting, inking, embossing, and paper feeding (including folding). Its working principle is as follows: the text and image to be printed are first made into a printing plate and mounted on the printing press. Ink is then applied to the areas of the plate where the text and image are located, either manually or by the printing press. The ink is then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics), thereby reproducing a printed product identical to the printing plate. When the printing press is in use, an automatic feeder is required to transport the paper into the press.

[0003] Existing automatic feeding devices are usually only used to transport paper. However, during the transportation process, if dust particles are attached to the surface of the paper, when the paper enters the printing press for printing, the ink will not adhere evenly during the printing process, causing defects such as white spots or blank areas in the printed area of ​​the paper, thereby affecting the printing quality. In view of this, we propose an automatic feeding device for a printing press. Utility Model Content
