In particular, in order to avoid the displacement of the packing box 29 caused by the different distances traveled by the two second pistons 7, a gear 27 and a rack 28 are provided, the gear 27 being rotated when the two second pistons 7 are moved relative to each other. When the gear 27 rotates, the two racks 28 move synchronously, so that the two second pistons 7 move synchronously, and therefore the two guide rails 10 move the same distance.

The method for scanning the code of the packing box 29 by adopting the code scanning device comprises the following steps:

s1, placing the packing box 29 on a conveying mechanism, and conveying the packing box 29 to the lower part of a code scanning box 1 through the conveying mechanism;

s2, driving the two guide rails 10 to approach each other through the first driving mechanism, so that a plurality of fixing mechanisms arranged below the guide rails 10 fix two opposite side walls of the packaging box 29;

s3, the two guide rails 10 are driven to ascend through the first driving mechanism, so that the packing box 29 is driven to ascend through the clamping plate 14 and the fixing mechanism, and along with the upward movement of the packing box 29, the first code scanner 17 scans the side wall of the packing box 29 firstly and then scans the bottom wall of the packing box 29;

s4, the clamping plate 14 is driven to move relative to the packing box 29 through the second driving mechanism, so that the area shielded by the clamping plate 14 leaks out, then the two guide rails 10 are driven to descend through the first driving mechanism, so that the packing box 29 is driven to descend through the clamping plate 14 and the fixing mechanism, and the packing box 29 is scanned again through the first code scanner 17 in the downward movement process of the packing box 29.

The working principle is as follows: placing the packing box 29 on the conveyer belt 23, starting the second motor 22, the output end of the second motor 22 driving the conveyer belt 21 to rotate, the conveyer belt 23 being driven to rotate when the conveyer belt 21 rotates, thereby conveying the packing box 29 placed on the conveyer belt 23, the packing box 29 being limited by the two guide plates 25 when moving, so that the packing box 29 moves to the middle part of the conveyer belt 23 for subsequent fixation, when the packing box 29 moves to the lower part of the code scanning box 1, the second output end 302 of the multistage hydraulic cylinder 3 contracts first, pushing the first piston 5 to move upwards, when the first piston 5 moves upwards, sucking the gas in the second cylinder 6 into the first cylinder 4, making the two second pistons 7 driving the two piston rods 8 to move towards each other, thereby driving the clamping plates 14 to move through the lifting rod 9 and the guide rail 10, so as to reduce the distance between the clamping plates 14 which are arranged oppositely, until the clamping plate 14 is pressed against the packing box 29, so that the packing box 29 is fixed by the fixing mechanisms of the plurality of clamping plates 14, then the first output end 301 of the multistage hydraulic cylinder 3 is contracted, so that the lifting rod 9 is driven to move upwards by the moving component, and further, the packing box 29 is driven to move upwards by the guide rail 10 and the clamping plate 14, when the packing box 29 moves upwards, the top wall of the packing box 29 is scanned by the second code scanner 18, the side wall of the packing box 29, which is not in contact with the fixing mechanism, is scanned by the third code scanner 19, the side wall of the packing box 29, which is in contact with the fixing mechanism, is scanned by the first code scanner 17, when the packing box 29 moves to the uppermost position, the bottom wall of the packing box 29 is scanned by the first code scanner 17, and due to the shielding of the clamping plate 14, the bar code may be blocked by the clamping plate 14, so that when the packing box 29 moves to the uppermost position, the clamping plate 14 is driven to move relative to the packing box 29 by the second driving mechanism, the lead screw 13 is driven to rotate by the rotation of the output end of the first motor 12 during driving, the slide seat 11 is driven to move when the lead screw 13 rotates, the clamping plate 14 is driven to move when the slide seat 11 moves, the threads on the two sides of the outer wall of the lead screw 13 are reversely arranged, so that the two slide seats 11 are relatively close to or far away from each other when the lead screw 13 rotates, the two clamping plates 14 are driven to relatively close to or far away from each other, the area shielded by the clamping plate 14 leaks out, the packing box 29 is scanned again by the first code scanner 17 in the downward movement process of the packing box 29, the bar code is prevented from being shielded by the clamping plate 14 and cannot be scanned, the first output end 301 of the multi-stage hydraulic cylinder 3 firstly extends out, the lifting rod 9 is driven to move downwards by the moving assembly, the clamping plate 14 is further driven to move downwards by the guide rail 10 and moves to the limit position, the second output end 302 of the multistage hydraulic cylinder 3 extends out to push the first piston 5 to move downwards, when the first piston 5 moves downwards, the gas in the first cylinder 4 is squeezed into the second cylinder 6, so that the two second pistons 7 drive the two piston rods 8 to move back to back, the lifting rod 9 and the guide rail 10 drive the clamping plates 14 to move, the distance between the oppositely arranged clamping plates 14 is increased, the packing box 29 is put down, and six faces of the packing box 29 are scanned.
