When the ejector rod of the air cylinder 11 extends downwards to move the pinch roller shaft fixing sliding block 12 downwards for a distance, the pinch roller shafts 13 fixed on the pinch roller shaft fixing sliding block 12 drive a plurality of upper synchronous conveying pinch rollers 14 to press on the synchronous conveying rollers 18, so that the printed paper 17 can be clamped; if the visual sensor 10 detects that the positioning position of the printing paper 17 set in the control system is offset by a distance from the paper feeding direction vertically, the first servo motor 29 can be controlled by a computer to drive the sliding table of the driving sliding rail pair 30 and drive the sliding table of the driven sliding rail pair 23, so that the sliding bottom plate 32 of the paper feeding positioning mechanism fixed on the sliding table translates by a distance along the direction vertical to the paper feeding direction, and the sliding bottom plate 32 of the paper feeding positioning mechanism drives the sliding bottom plate 21 of the paper feeding positioning mechanism, the upper synchronous conveying pinch roller 14 and the lower synchronous conveying roller 18 to clamp the printing paper 17 through the rotating bottom plate rotating shaft 26, and moves together with the sliding bottom plate 32 of the paper feeding positioning mechanism by a distance along the direction vertical to the paper feeding direction, so as to adjust the printing paper 17 to the set positioning position; if the visual sensor 10 for positioning the printing paper detects that the positioning position of the printing paper 17 set in the control system deviates from the paper feeding direction by an angle, the computer controls the second servo motor 28 to drive the worm of the worm gear pair 27 to drive the worm wheel to rotate by an angle, and the rotating base plate rotating shaft 26 rotates the paper feeding positioning mechanism to rotate the base plate 21, the upper synchronous conveying pinch roller 14 and the lower synchronous conveying roller 18 to clamp the printing paper 17, and rotates by an angle relative to the paper feeding direction, so that the printing paper 17 is adjusted to the set positioning position; meanwhile, the pressing wheel shaft fixing sliding block 12 drives the front gauge 15 to move downwards, so that the positioning surface of the front gauge 15 is lower than the paper conveying plane, and therefore, the printing paper 17 can pass through; after the positioning is completed, the driving mechanism drives the upper synchronous conveying pinch roller 14 and the lower synchronous conveying roller 18 to relatively roll at the same linear speed, the printing paper is fed between the die cutting roller 5 and the bottom roller 33, when the printing paper 17 passes between the die cutting roller 5 and the bottom roller 33, the die cutting roller 5 and the bottom roller 33 relatively roll, and the precise embossing and indentation die cutting processing of the printing paper 17 is completed through the installed embossing knife 3, the embossing bottom die 2, the embossing upper die 6, the embossing bottom die 31, the die cutting knife 7 and the transverse die cutting knife 8. The printed paper 17 after embossing, creasing and die cutting is transported to the collection unit by the collection belt drive roller 34 and the collection belt 35, and is collected and stacked.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather to enable any modification, equivalent replacement, improvement or the like to be made within the spirit and principles of the utility model.
