The guide rail 2 is fixedly arranged at the bottom of the conveyor 1. The conveyor 1 is located between the two groups of first limit plates 24. The package box is driven to move to the bottom of the printing press through the conveyor 1. When the package box moves between the two groups of first limit plates 24, the first motor 23 drives the two groups of first internal threaded sliders 21 to move inward synchronously through the first bidirectional lead screw 22, and then drives the two groups of first limit plates 24 to approach the front and rear sides of the package box. When the roller 25 is in contact with the front and rear sides of the package box, the first motor 23 stops working, thereby completing the centering of the front and rear of the package box. The second alignment component includes a second bidirectional lead screw 41. The two A slide groove is provided at the top of the first limit plate 24 on the front side of the group of first limit plates 24, and the second bidirectional screw rod 41 is rotatably set in the slide groove. Two groups of second internally threaded sliders 4 are evenly screwed on the outer wall of the second bidirectional screw rod 41, and a second limit plate 42 is fixedly set on the top of the second internally threaded slider 4. A second motor 43 is fixedly set on the right side of the first limit plate 24 on the front side of the two groups of first limit plates 24, and the left side of the output end of the second motor 43 passes through the right side of the first limit plate 24 on the front side of the two groups of first limit plates 24 and is connected to the second bidirectional screw rod 41.

[0022] Working principle: the packaging box is driven to move to the bottom of the printing press through the conveyor 1. When the packaging box moves between the two groups of first limit plates 24, the first motor 23 drives the two groups of first internal thread sliders 21 to move inward synchronously through the first bidirectional screw rod 22, thereby driving the two groups of first limit plates 24 close to the front and rear sides of the packaging box. When the roller 25 is in contact with the front and rear sides of the packaging box, the first motor 23 stops working to complete the centering of the front and rear of the packaging box. At the same time, when the first limit plate 24 moves, it drives the two groups of second limit plates 42 to move above the conveyor 1, and the two groups of second limit plates 42 are respectively placed on the left and right sides of the packaging box. The second motor 43 drives the two groups of second internal thread sliders 4 to move synchronously through the second bidirectional screw rod 41, thereby driving the two groups of second limit plates 42 to move synchronously with the left and right sides of the packaging box. The right two sides are in contact, and the left and right sides of the packaging box are squeezed by two groups of second limiting plates 42 to center the left and right sides of the packaging box. The roller 25 can assist the packaging box to move stably left and right on the two groups of first limiting plates 24, so as to assist in completing the centering of the left and right sides of the packaging box. When the two groups of first limiting plates 24 move, the sleeve 31 and the positioning rod 33 at the bottom thereof will be driven to move synchronously. At this time, the first support sleeve 32 and the second support sleeve 34 can assist the sleeve 31 and the positioning rod 33 to move stably, thereby playing the effect of assisting the two groups of first limiting plates 24 to move stably. When the sleeve 31 and the positioning rod 33 move inward synchronously, the positioning rod 33 will be inserted into the sleeve 31, thereby improving the working stability of the entire stabilizing assembly, thereby ensuring the reliability of the device.
