Its function is to accurately separate the top sheet of paper from the paper pile and transport it to the next station. There is a mechanism in the paper feeder called a paper aligning mechanism, which plays the role of aligning the top sheet of paper in the paper pile. In the past, the paper aligning clappers were mostly composed of multiple sheet metal parts and optical axes, which required a lot of time to adjust each sheet metal part to the same plane during the installation process, making the entire assembly process inefficient. The sheet metal parts are easily deformed during use. If the mechanism is damaged, it needs to be disassembled as a whole, which is troublesome to replace. Summary of the invention

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0017] As Figures 1-3 shown, a paper aligning and flapping plate mechanism of a paper feeder includes a paper feeder frame 16. A rotating shaft 13 and a round shaft 18 are provided in the middle on both sides of the paper feeder frame 16. The connecting shaft one 3, the connecting shaft two 4, and the connecting shaft three 5 are connected and fixed to the baffle plate 2 through the standard part GB70.1-2000 hexagon socket head cap screws. Standard parts GB12613.1-2002 drawn cup plain bearings are installed between the connecting shaft one 3, the connecting shaft two 4, the connecting shaft three 5 and the fixed seat 1, enabling the connecting shaft one 3, the connecting shaft two 4, the connecting shaft three 5 and the baffle plate 2 to rotate. Through the above connections, Figure 2The shown components are turned into an integral platen mechanism 17; the platen mechanism 17 is fixedly connected to the paper feeding machine frame 16 by hexagon socket head cap screws of standard part GB70.1-2000; the platen mechanism 17 is fixedly connected to the locking block 6 by hexagon socket head cap screws of standard part GB70.1-2000, the first small shaft 8 is locked and fixed to the locking block 6 by hexagon socket grub screws of standard part GB77-2000, and standard parts GB12613.1-2002 drawn shaft sleeves are installed between the connecting plate 7 and the first small shaft 8 and the hexagonal shaft 9 so that the connecting plate 7 can rotate. The hexagonal shaft 9 is threadedly connected to the swing rod 10, and the locking retaining ring 11 is used to fix the position of the swing rod 10. A standard part GB276-94 deep groove ball bearing is installed between the swing rod 10 and the round shaft 18 so that the swing rod 10 can rotate leftward. The cam 12 is locked and fixed to the rotating shaft 13 by hexagon socket grub screws of standard part GB77-2000. A standard part GB1096-1979 ordinary flat key is installed between the rotating shaft 13 and the sprocket 14. The GB276-94 deep groove ball bearing 20 is fixed to the swing rod 10 through the connecting small shaft 19. One end of the tension spring 15 is connected to the swing rod 10 by hexagon socket head cap screws of standard part GB70.1-2000, and the other end is connected to the paper feeding machine 16. The tension of the tension spring 15 makes the GB276-94 deep groove ball bearing 20 installed on the swing rod 10 tangent to the bearing 12 through the hexagon socket head cap screws at both ends. Through the above connections, when the sprocket 14 is driven, the rotating shaft 13 is driven by the standard part GB1096-1979 ordinary flat key, thereby driving the cam 13 locked and fixed by the hexagon socket grub screws of standard part GB77-2000. During the rotation process of the cam 12, with the change of the cam curve, under the action of the tension of the tension spring 15, the GB276-94 deep groove ball bearing 20 tangent to the cam 13 moves along the cam curve of the cam 13, thereby driving the movement of the swing rod 10, and further driving the platen mechanism 17 through the connecting plate 7, the first small shaft 8, the hexagonal shaft 9, and the locking block 6, so as to realize the function of aligning the uppermost paper of the paper stack.
