The invention discloses a pressure adjusting device for a paper conveying part of a printing machine by utilizing negative pressure, which comprises a bottom frame, a conveying table is arranged on one side of the outer wall of the top of the bottom frame, cross rods are fixedly connected to the outer walls of the two sides of the bottom frame, connecting sleeves are arranged on the outer walls of one sides of the cross rods, and connecting shafts are connected to the inner walls of the connecting sleeves through bearings; the two ends of the connecting shaft are fixedly connected with a linkage fluted disc and a pressure rotating disc correspondingly, a fixed shaft is arranged on the outer wall of one side of the pressure rotating disc, the outer wall of the fixed shaft is sleeved with a movable rod, a connecting rod is arranged at the bottom end of the movable rod, a fixed rod is installed on the outer wall of the bottom of the transverse rod, and an extrusion mechanism is installed at one end of the fixed rod; and the extrusion mechanism is located below the pressure rotating disc, and linkage fit is formed between the connecting rod and the extrusion mechanism. The pressure adjusting device of the printing machine paper conveying part utilizing the negative pressure has the effects that paper conveying is stable, paper clamping is avoided, and static electricity is effectively prevented.
Description
technical field [0001] The invention relates to the technical field of negative pressure printing presses, in particular to a pressure regulating device for a paper feeding part of a printing press using negative pressure. Background technique [0002] The printer is a machine that prints text and images. Modern printing machines are generally composed of plates, inking, embossing, paper feeding (including folding) and other mechanisms. Its working principle is: first make the text and images to be printed into a printing plate, install it on the printing machine, and then manually or by the printing machine apply the ink to the place where the text and images are on the printing plate, and then directly or indirectly transfer the ink. Printing onto paper or other substrates such as textiles, sheet metal, plastic, leather, wood, glass and ceramics to reproduce the same print as the printing plate. The invention and development of the printing press played an important role...
