By setting up the pusher plate 33, the reciprocating motor 35, the transmission shaft 32 and the positioning plate 42, it is convenient to apply lateral force to the paper so that the paper is aligned in the lateral direction.

[0025] The paper feeding mechanism 2 includes two vertical plates 21 arranged opposite to each other. A first paper feeding roller 22 and a second paper feeding roller 23 are arranged between the two vertical plates 21. The first paper feeding roller 22 is arranged below the second paper feeding roller 23, and a servo motor 24 for driving the first paper feeding roller 22 to rotate is provided on the vertical plate 21.

[0026] The paper pushing mechanism 3 includes two longitudinally opposite transverse plates 31 on the platform plate 1. A transmission shaft 32 is rotatably connected between the two transverse plates 31. A paper pushing plate 33 is fixed on the transmission shaft 32. A limit block 34 is provided on the platform plate 1. A limit groove adapted to the limit block 34 is provided on the paper pushing plate 33.

By setting the screw 47, the movable block 46 and the bearing, it is convenient to adjust the limiting distance according to the size of the paper.

[0028] The positioning plate 42 is provided with a lifting groove 6, and a first cylinder 7 is provided inside the lifting groove 6. An installation block 8 is fixed to the output end of the first cylinder 7, and the installation block 8 is fixed to the lower pressure plate 49.

[0032] Working principle: The printed paper passes sequentially through the gap between the first feed roller 22 and the second feed roller 23 and falls onto the support plate 41. After one or more sheets of paper are placed, the servo motor 24 is turned on, driving the transmission shaft 32 to rotate, causing the pusher plate 33 to rotate. The pusher plate 33 is stopped by the limit block 34 and rotated to a vertical position. The positioning plate 42 is used to fine-tune and limit the lateral position of the paper. Then, the second cylinder 11 is turned on, driving the moving plate 44 to move. The fixed plate 43 is used to fine-tune and limit the longitudinal position of the paper. When the pressure between the moving plate 44 and the paper suddenly increases, the pressure sensor is sensed and sends an electrical signal to the control panel. The control panel sends an electrical signal to the second cylinder 11, causing the second cylinder 11 to stop. Then, the first cylinder 7 is turned on, causing the lower pressure plate 49 to descend to the paper surface and smooth the top layer of paper. The paper positioning is completed. Thus, this printing paper device has the effect of quickly positioning and aligning paper in multiple directions.
