[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1

[0022] See also Figure 1-Figure 4 The illustrated embodiment shows a paper pressing mechanism of a paper discharge section of a paper feeder, comprising a crossbeam 1, the ends of which are connected to a bracket 2 via a connecting assembly 3. A paper pressing assembly 4 is provided at the bottom of the crossbeam 1. The paper pressing assembly 4 includes a motor 1 41, the output end of the motor 1 41 is connected to a bidirectional threaded rod 42, the ends of the bidirectional threaded rod 42 are spirally connected to a moving block 43, the bottom of the moving block 43 is rotatably connected to a connecting rod 44, and the connecting rod 44 is rotatably connected to a suspension 46 via a connecting arm 45.

[0023] The two ends of the bottom of the suspension 46 are rotatably connected to the paper pressing wheels 47;

[0024] A connecting frame 48 is fixedly provided at the bottom of the beam 1, and the bidirectional threaded rod 42 is rotatably provided on the connecting frame 48, and the top of the moving block 43 is in contact with the bottom of the beam 1;

[0025] A moving slot 23 is formed on the top of the bracket 2, and a mounting plate 21 is connected to the bottom of the bracket 2, and mounting bolts 22 are installed on the mounting plate 21;

[0026] The connecting assembly 3 includes a second motor 31, the output end of the second motor 31 is connected to a worm 32, the worm 32 is meshed with a worm wheel 331, and the worm wheel 331 is fixedly arranged in the middle of a rotating shaft 33, and the rotating shaft 33 is rotatably arranged in the crossbeam 1;

[0027] Both ends of the rotating shaft 33 are connected to a screw rod 34 , and the screw rods 34 at both ends of the rotating shaft 33 have opposite spiral directions. The screw rod 34 is spirally connected to the bracket 2 , and one end of the screw rod 34 is slidably set in the movable groove 23 ;

[0028] Sliding rods 35 are fixedly provided at both ends of the crossbeam 1 , and the sliding rods 35 are slidably provided in another movable groove 23 at the top of the bracket 2 .

[0029] In this solution, the mechanism is installed on the paper feeder via the bracket 2, and the distance between the two brackets 2 is adjusted via the connecting assembly 3, so that the bracket 2 can be installed on paper feeders of different models. During adjustment, the motor 2 31 is used to control the rotation of the worm 32. Through the engagement of the worm 32 with the worm wheel 331, the rotation of the worm 32 controls the rotation of the worm wheel 331, which in turn drives the rotation of the rotating shaft 33. During the rotation of the rotating shaft 33, the screw rods 34 at both ends of the rotating shaft 33 rotate accordingly. The screw rods 34 are spirally connected to the brackets 2, so that when the screw rods 34 rotate, the brackets 2 at both ends of the beam 1 move toward each other, making the mechanism applicable to paper feeders of different models.

[0030] When the bracket 2 moves, the spiral rod 34 and one end of the slide rod 35 move in the moving groove 23. At the same time, the slide rod 35 can guide the movement of the bracket 2 to ensure that the bracket 2 moves along a predetermined straight line direction and prevent deviation, distortion or rotation during the movement, thereby ensuring the accuracy and stability of the movement. When the bracket 2 is in contact with the surface of the paper feeder, the bracket 2 is fixed to the paper feeder using the mounting bolts 22, thereby completing the installation of the mechanism.

[0031] When pressing paper, the motor 41 is used to control the two-way threaded rod 42 to rotate. During the rotation of the two-way threaded rod 42, the moving blocks 43 spirally connected at both ends of the two-way threaded rod 42 can be controlled to move. Since the top of the moving block 43 fits with the bottom of the beam 1, the moving block 43 can fit with the beam 1 and move toward each other, thereby making the distance between the two moving blocks 43 closer. During the movement of the moving block 43, the angle between the two connecting rods 44 becomes smaller, so that the connecting rod 44 can rotate around the moving block 43 and gradually tend to a vertical state. In this process, since the connecting rod 4 4 is rotatably connected to the connecting arm 45, and the connecting arm 45 is fixed to the top of the suspension 46. Therefore, when one end of the connecting rod 44 rotates around the connecting arm 45, it pushes the suspension 46 to move downward, so that the paper pressing wheel 47 connected to the suspension 46 is in contact with the paper, thereby achieving the purpose of adjusting the height of the suspension 46 in response to paper of different thicknesses. At the same time, the motor 1 41 is used to control the rotation of the bidirectional threaded rod 42. When the motor 1 41 stops driving, the bidirectional threaded rod 42 can be locked to prevent the bidirectional threaded rod 42 from rotating due to external interference, thereby preventing the suspension 46 from deviating from its position due to external interference.
