[0032] A slide groove 101 is provided on the top wall of the leveling device body 1, and a mounting groove 102 is provided on the side wall of the leveling device body 1. The transmission mechanism 2 is installed on the leveling device body 1, and the transmission mechanism 2 includes a transmission roller 21 rotatably connected to the inner wall of the leveling device body 1, a conveyor belt 22 arranged on the transmission roller 21, and a transmission motor 23 fixed to the side wall of the leveling device body 1, and the output shaft of the transmission motor 23 passes through the leveling device body 1 and is fixed to the transmission roller 21.

[0033] The leveling assembly 3 is mounted on the leveling device body 1, and the leveling assembly 3 includes a cylinder 31, a mounting plate 32, and a paper pressing roller 33. The cylinder 31 is fixed on the upper surface of the leveling device body 1, and the piston rod of the cylinder 31 penetrates the leveling device body 1 and is slidably connected. The mounting plate 32 is a plate-like structure with a U-shaped cross section, and the mounting plate 32 is fixed to the end of the piston rod of the cylinder 31. The paper pressing roller 33 is a round roller-like structure, and the paper pressing roller 33 is rotatably connected to the mounting plate 32.

[0034] The first guide block 4 is fixed on the inner wall of the leveling device, and the lower surface of the first guide block 4 is slidably connected to the conveyor belt 22. The slider 5 is a rectangular parallelepiped structure, and the slider 5 is arranged in the slide groove 101 and is slidably connected to the slide groove 101. The connecting rod 6 is a vertically arranged round rod structure, and the connecting rod 6 is fixed to the lower surface of the slider 5. The second guide block 7 is fixed to the lower end of the connecting rod 6, and the lower surface of the second guide block 7 is rollingly connected to the conveyor belt 22.

[0035] The driving assembly 8 is mounted on the leveling device body 1 and is used to drive the slider 5 to move. The driving assembly 8 includes a driving motor 81 and a threaded rod 82. The driving motor 81 is fixed on the inner wall of the mounting groove 102, and the output shaft of the driving motor 81 passes through the inner wall of the mounting groove 102 and extends to the slide groove 101. The threaded rod 82 is a horizontally arranged rod-shaped structure, and the end of the threaded rod 82 is fixed to the end of the output shaft of the driving motor 81. The threaded rod 82 passes through the slider 5 and is threadedly connected. The end of the threaded rod 82 away from the driving motor 81 is rotatably connected to the inner wall of the slide groove 101, and the axis of the threaded rod 82 coincides with the axis of the output shaft of the driving motor 81.

[0036] When it is necessary to press the edge of the paper, the staff places the paper on the conveyor belt 22 and on the side wall of the first guide block 4, and then drives the threaded rod 82 to move through the driving motor 81. Since the threaded rod 82 is threadedly connected to the slider 5, and the slider 5 is slidingly connected to the slide groove 101, the slider 5 moves axially along the threaded rod 82 in the slide groove 101, so that the connecting rod 6 and the second guide block 7 move toward the first guide block 4, so that the second guide block 7 cooperates with the first guide block 4 and presses the edge of the paper, and then the paper pressing roller 33 is pressed to flatten the paper by adjusting the cylinder 31, which reduces the probability of paper moving on the transmission mechanism 2 and facilitates the pressing of papers of different widths.

[0037] In order to reduce the probability of paper displacement on the conveyor belt 22, a rubber belt 9 is fixedly sleeved on the outer wall of the conveyor belt 22. The rubber belt 9 is made of rubber material and its surface has a large friction coefficient, which increases the friction between the conveyor belt 22 and the paper, thereby reducing the probability of paper displacement on the conveyor belt 22.

[0038] In order to reduce the friction between the first guide block 4, the second guide block 7 and the rubber belt 9, a plurality of balls 10 rollingly connected to the rubber belt 9 are embedded in the lower surface of the first guide block 4 and the lower surface of the second guide block 7.

The controller 11 is electrically connected to the cylinder 31, the transmission motor 23 and the drive motor 81. The setting of the controller 11 allows the staff to control the leveling component 3, the drive component 8 and the transmission mechanism 2 through the controller 11, thereby facilitating the staff to operate the leveling device to level the paper.

[0041] In order to facilitate the maintenance of the drive motor 81, a flared groove 103 is opened at the intersection between the inner wall of the installation groove 102 and the leveling device body 1, and the side wall of the leveling device body 1 is hinged with a trapezoidal baffle 12 that cooperates with the flared groove 103. The trapezoidal baffle 12 protects the installation groove 102, reduces the probability of damage to the drive motor 81, and facilitates the maintenance of the drive motor 81.

[0042] In order to facilitate timely adjustment of the leveling device, a transparent window 13 is provided on the side wall of the leveling device body 1. The transparent window 13 allows the staff to observe the flatness of the paper in the leveling device body 1 through the transparent window 13, thereby facilitating timely adjustment of the leveling device.

[0043] The use principle of a paper printing smoothing device of a printing machine in the present embodiment is as follows: when it is necessary to press the edge of the paper, the staff places the paper on the conveyor belt 22 and on the side wall of the first guide block 4, and then drives the threaded rod 82 to move through the driving motor 81. Since the threaded rod 82 is threadedly connected to the slider 5, and the slider 5 is slidably connected to the slide groove 101, the slider 5 moves axially along the threaded rod 82 in the slide groove 101, so that the connecting rod 6 and the second guide block 7 move toward the first guide block 4, so that the second guide block 7 cooperates with the first guide block 4 and presses the edge of the paper, and then the paper pressing roller 33 presses the paper for smoothing by adjusting the cylinder 31, which reduces the probability of paper moving on the transmission mechanism 2 and facilitates pressing of papers of different widths.

[0044] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
