[0002] Modern printing presses generally consist of mechanisms for plate mounting, inking, printing, and paper feeding. Their working principle is as follows: first, the text and images to be printed are made into a printing plate, which is then mounted on the printing press. Ink is then applied manually or by the printing press to the areas on the printing plate containing the text and images, and the ink is directly or indirectly transferred to paper or other substrates, thus reproducing a printed product identical to the printing plate. The invention and development of printing presses have played a vital role in the dissemination of human civilization and culture. Screen printing machines are a type of printing press.

[0003] Existing screen printing machines typically use a feeding method where the operator holds the thin cardboard and places it on a conveyor belt at the bottom of the machine. The conveyor belt then transports the cardboard to the printing head for screen printing, which is difficult to reduce labor costs. Therefore, this paper studies and improves the existing structure and its shortcomings to provide a feeding device for a thin cardboard printing machine, aiming to achieve greater practical value.
