The invention relates to the technical field of printing plates, and particularly discloses a screen-free printing plate of a battery piece. The screen-free printing plate comprises a workbench and aprinting plate main body, vertical stand columns are symmetrically and fixedly arranged at the left end and the right end of the upper surface of the workbench, the top ends of the stand columns are connected through a horizontal ejector rod, the lower surface of the middle position of the ejector rod is fixedly provided with a first motor, an output shaft of the first motor is coaxially connectedwith a driving wheel, an installation groove is formed in each stand column, screw rods are rotatably arranged in the installation grooves, driven discs are coaxially connected to the top ends of thescrew rods, the printing plate main body is fixedly arranged on the lower surface of the middle position of a cross rod, the two ends of the cross rod are nested on the screw rods, a rotating base isrotatably arranged on the upper surface of the workbench, the edge of the rotating base is provided with teeth, the side edge of the rotating base is fixedly provided with a second motor inside the workbench, and an output shaft of a second motor is coaxially connected with a driving gear. The screen-free printing plate has the advantages of being simple in structure, stable in lifting, smooth inadjustment, high in printing quality and convenient to implement and popularize.
