s2: the driving motor (22) is started, the driving motor (22) drives the driving shaft (211) to rotate, the driving shaft (211) drives the driving rod (2111) to rotate, the driving rod (2111) drives the driving block (23) to slide in the driving groove (213), the driving block (23) drives the connecting shaft (215) to move, and the connecting shaft (215) drives the screen printing plate (12) to move to one side close to the storage rack (11); when the screen printing plate (12) moves, the stabilizing block (242) is pulled to slide in the stabilizing groove (241);

s20: in the moving process of the connecting shaft (215), one end of a rotation gear (216) is driven, the rotation gear (216) is matched with a rotation inner gear (2131) to drive the connecting shaft (215) to rotate, and the connecting shaft (215) drives the screen printing plate (12) to rotate, so that the possibility of overturning the screen printing plate (12) is reduced;

s3: after the silk screen printing plate (12) is close to the storage rack (11), the driving motor (22) stops working, the silk screen printing plate (12) stops moving, the feeding motor (31) is started, the feeding motor (31) simultaneously drives the feeding wheel (32) and the driving material conveying roller (33) to rotate, the feeding wheel (32) conveys the paper boards to be printed into the feeding gap (341) from the storage rack (11), and the driving material conveying roller (33) conveys the paper boards to be printed onto the silk screen printing plate (12);

s30: when a paper board to be printed is placed in the storage rack (11), the paper board to be printed falls on the ejector plate (41), after a gap is formed between the feeding wheel (32) and the paper board to be printed, the ejector motor (43) is started to drive the ejector lead screw (42) to rotate, and the ejector lead screw (42) drives the ejector plate (41) to move upwards to push the paper board to be printed upwards;

s4: after the paper board to be printed falls on the screen printing plate (12), the positioning thin plate (51) limits the position of the paper board to be printed on the screen printing plate (12), the positioning motor (533) drives the positioning push plate (53) to move, and after the positioning push plate (53) is abutted against the paper board to be printed, the paper board to be printed is pushed to abut against the limiting thin plate (52), so that the paper board to be printed is positioned;

s40: the method comprises the steps that a driving motor (22) is started while a paperboard to be printed is positioned, the step S2 is repeated, a screen printing plate (12) is driven to move towards one side close to a screen printing machine (1), and meanwhile, an adjacent screen printing plate (12) is driven to move towards one side close to a storage rack (11);

s5: when the screen printing plate (12) is close to the screen printing machine (1), the driving motor (22) is stopped, the screen printing machine (1) prints the paper board to be printed, and meanwhile, the step S3 is repeated, and the paper board to be printed is transmitted to the adjacent screen printing plate (12);

s6: after the printing of the paper board to be printed is finished, taking down the paper board;

s7: and repeating the steps S4-S6 to automatically finish feeding.
