[0002] Modern printing presses are generally composed of mechanisms such as plate loading, inking, pressing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate, which is then installed on the printing press. Then, ink is applied to the places where the text and image are on the printing plate by hand or by the printing press, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass and ceramics), thereby replicating the same printed product as the printing plate;

[0003] When paper and other products are conveyed to a digital printing machine, the corners of the paper may be warped. After the warped paper is conveyed to the digital printing machine, the digital printing machine may be jammed, affecting printing efficiency.

[0004] In view of this, a digital printing press anti-jamming device is proposed. Utility Model Content
