[0020] The following is combined with Figure 1-4 This application is described in further detail.

[0021] The present application embodiment discloses a printing paper deviation correction device. Figure 1-4A printing paper deflection correction device comprises a base frame 1 and a plurality of supporting legs 2 fixedly connected to the outer side wall of the base frame 1, a shaft seat 17 is fixedly connected to the outer side wall of the top middle section of the base frame 1, a rotating shaft 3 is rotatably connected to the inner wall of the shaft seat 17, a movable frame 4 is fixedly connected to the top of the rotating shaft 3, a deflection correction roller 5 is rotatably connected to the inner wall of the movable frame 4, and a driving mechanism for driving the deflection correction roller 5 to correct the deflection is installed on the outer wall of the base frame 1;

[0022] The driving mechanism includes an electric push rod 8 rotatably connected to the outer wall of the top of the base frame 1 through a fixed seat 7, the output end of the electric push rod 8 is fixedly connected to a connecting block 9, the outer wall of the rotating shaft 3 is fixedly connected to a driving plate 6, and one end of the driving plate 6 away from the rotating shaft 3 is hinged to the connecting block 9;

[0023] A correction sensor 15 is fixedly installed on the outer wall directly in front of the base frame 1 through a mounting rod 14, and a control unit 16 is fixedly installed on the outer wall of one of the supporting legs 2 located behind the base frame 1. The correction sensor 15 is electrically connected to the control unit 16, and the control unit 16 is electrically connected to the electric push rod 8.

[0024] The top outer wall of the bottom frame 1 behind the deviation-correcting roller 5 is fixedly connected to two fixing plates 10 , and the outer walls of the two fixing plates 10 are rotatably connected to the first tensioning roller 11 .

[0025] Two support frames 12 are fixedly connected to the outer side wall directly in front of the base frame 1. The ends of the two support frames 12 away from the base frame 1 are rotatably connected to the second tensioning roller 13. The paper is laid on the outer walls of the first tensioning roller 11, the deviation correction roller 5 and the second tensioning roller 13 in sequence.

[0026] The correction sensor 15 adopts a high-precision photoelectric sensor, which has the advantages of fast response and high-precision measurement, and is used to accurately identify the edge of the paper and obtain position information.

[0027] The control unit 16 controller adopts a high-performance microprocessor, which can quickly process large amounts of data and achieve precise control.

[0028] The implementation principle of a printing paper correction device in the embodiment of the present application is as follows: in actual application, the paper is led out from an external winding roller (not shown in the figure), and the paper is laid on the first tensioning roller 11, the correction roller 5 and the second tensioning roller 13 in sequence, such as Figure 1 As shown, the end of the paper leading out is installed on the printing press, and then the printing work can be carried out, and the printing press is started, and the printing press prints the paper and drives the paper to move;

[0029] During the movement of the paper, the second tensioning roller 13, the deflection correction roller 5 and the support frame 12 are driven to rotate. The second tensioning roller 13 and the support frame 12 can tension the paper so that the paper and the deflection correction roller 5 are always in contact. The device starts to correct the deflection of the paper. When the paper moves, its edge is always in the deflection correction sensor 15. The deflection correction sensor 15 can detect the deviation of the paper in real time. When the paper deviates from the deflection correction sensor 15, the data will be transmitted to the control unit 16. The control unit 16 calculates the deflection correction amount according to the received data, and controls the extension and contraction amount of the electric push rod 8 in the driving mechanism. The output end of the electric push rod 8 is extended and contracted to drive the connecting block 9 to move. Since the connecting block 9 is hinged with the driving plate 6, the connecting block 9 pushes or pulls the driving plate 6 to rotate. The driving plate 6 drives the rotating shaft 3 to rotate on the inner wall of the shaft seat 17. At this time, the rotating shaft 3 drives the movable frame 4 to adjust a certain angle horizontally, so that the deflection correction roller 5 adjusts the horizontal angle to correct the paper.

[0030] like Figure 1 As shown, when the correcting roller 5 rotates horizontally clockwise through the movable frame 4, the paper will move to the left for correction. When the correcting roller 5 rotates horizontally counterclockwise through the movable frame 4, the paper will move to the right for correction, thereby achieving rapid and accurate correction of the printed paper. This device not only improves printing efficiency, but also ensures printing quality.
