[0022] Example

[0023] like Figure 1-Figure 3 As shown, this embodiment provides a deviation correction device for a paper bag printing machine, comprising a left deviation correction unit and a right deviation correction unit which are symmetrically arranged on both sides of a conveyor belt mechanism;

[0024] The left deviation-correcting unit comprises a side fixing plate, and a rotating roller unit and a guide fixing unit which are sequentially arranged on the side fixing plate;

[0025] The rotating roller unit includes a fixed square frame 13, in which a plurality of rotating rollers 8 (four as shown in the figure) are arranged at intervals in the longitudinal direction, and the upper roller shaft and the lower roller shaft of each rotating roller 8 are respectively rotatably connected with the upper frame edge and the lower frame edge of the fixed square frame 13, and the upper roller shaft is connected with a driven sprocket 12 after passing through the upper frame edge, and a driving motor 16 is arranged on one side of the fixed square frame 13, and the output shaft of the driving motor 16 is provided with a driving sprocket 15, and the driving sprocket 15 is connected with the driven sprocket 12 through a chain 9, so as to drive the rotating roller 8 to rotate, and all the rotating rollers can be driven to rotate by one driving motor;

[0026] The guiding solid unit includes a bent plate 5 and a transverse plate 20 which are arranged at intervals up and down to form a paper bag channel. The bent plate 5 includes an oblique part and a transverse part connected in sequence, and the transverse plate 20 is arranged parallel to the transverse part.

[0027] It should be noted that when in use, the rotating roller of the left correction unit rotates counterclockwise, and the rotating roller of the right correction unit rotates clockwise. The paper bag enters from the end away from the printing machine body and gradually approaches the printing machine body. When the inclined part of the paper bag contacts the rotating roller on the right, it rotates clockwise, which will push the paper bag apart and move it to the other side. Similarly, when the inclined part of the paper bag contacts the rotating roller on the left, it rotates counterclockwise, which will push the paper bag apart and move it to the other side, thereby achieving the correction effect. In addition, a guide solidification unit is provided, and the side of the paper bag channel facing the direction of the paper bag is open, so that the paper bag can enter smoothly. After entering, it will pass through the transverse part and the transverse plate part, and the height will be fixed by the paper bag channel, so that the quality is better when printing.

[0028] It should be noted that the structure of the right correcting unit is symmetrical to that of the left correcting unit, and therefore, its structure will not be described in detail, and reference will be made to the description of the structure of the left correcting unit.

[0029] Preferably, a fixing structure of a fixing frame 13 is provided. This structure enables the rotating roller to adjust its position in the left-right direction, so as to adapt to paper bags of different sizes. Specifically, the fixing frame 13 is connected to a U-shaped connecting frame 14, and the two sides of the U-shaped connecting frame 14 are respectively connected to the two side sides of the fixing frame 13, and the middle side of the U-shaped connecting frame 14 is respectively slidably and threadedly connected to the side fixing plate 4 through a parallel guide rod 7 and a screw rod 10, and the fixing frame 13 can be driven to move by rotating the screw rod 10, thereby realizing the position adjustment of the rotating roller in the left-right direction.

[0030] Wherein, a locking nut 11 is respectively threadedly connected on both sides of the screw rod 10 and the side fixing plate 4 , and the screw rod is fixed by the locking nut 11 .

[0031] Preferably, two rows of annular first negative pressure suction holes 2 are arranged at intervals on the conveyor belt 1 of the conveyor belt mechanism, and each row of first negative pressure suction holes 2 includes a plurality of holes arranged at intervals along the circumferential direction; a negative pressure suction block 18 is arranged below the side of the conveyor belt 1 close to the printer body 2, and the negative pressure suction block 18 is a cavity structure, and two long strip negative pressure suction holes 17 connected to the cavity structure are arranged on its upper wall, and the positions of the two long strip negative pressure suction holes 17 correspond to the positions of the two rows of first negative pressure suction holes 2, and are arranged on the lower side of the two rows of first negative pressure suction holes 2, and the negative pressure suction block 18 is connected to the negative pressure device 19 through a pipeline. The negative pressure device 19 generates air suction, thereby generating negative pressure in the cavity structure, and then the long strip negative pressure suction holes and the first negative pressure suction holes generate suction, which can absorb the paper bag, so that its position will not change easily during printing, and the printing quality can be improved.

[0032] The negative pressure device is an air pump or other device capable of generating negative pressure.

[0033] In addition, the conveyor belt mechanism in the present application adopts the structure in the prior art, including a conveyor belt and an active roller and a driven roller connected by the conveyor belt. The active roller is connected to the motor transmission and rotates under the drive of the motor, thereby driving the conveyor belt to rotate.

[0034] It should be noted that the structures not described in detail in the present application are all based on known technologies.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate and explain the present invention, and are not intended to limit the present invention to the scope of the described embodiments. In addition, those skilled in the art can understand that the present invention is not limited to the above embodiments, and more variations and modifications can be made according to the teachings of the present invention, and these variations and modifications all fall within the scope of protection claimed by the present invention.
