In this embodiment, the paper roll after production needs to be segmented and packaged. At this time, the personnel perform segmentation according to the diameter of the paper roll. Adjust the distance between the connecting belt 13 and the guide rod 3 to make the distance smaller than the diameter of the paper roll, and then rotate the threaded column 7 in the threaded hole, so that the bottom end of the threaded column 7 rests on the adjusting rod 6, so that the guide rod 3 is fixed, and the guide rod 3 can be firmly fixed through the multiple adjusting holes, so that the paper roll in the previous process can fall into the guide rod 3 and the connecting belt 13, and the first adjusting shaft 9 can be rotated by the driving mechanism, and the first adjusting shaft 9 can be stably rotated and moved through the first bearing seat 8, and the connecting belt 13 can be driven to rotate by the first adjusting shaft 9 through the connecting wheel 12, and the connecting wheel 1 on the second adjusting shaft 11 can be driven by the connecting belt 13. 2 follows the rotation, and the second bearing seat 10 can make the second adjustment shaft 11 rotate at a stable angle. The paper roll can move on the connecting belt 13 and the guide rod 3 through the rotating connecting belt 13, and then fall from one end of the guide rod 3, which is convenient for personnel to carry out the post-segment packaging operation. By providing two symmetrically arranged paper tail dropping mechanisms, the two paper rolls can be guided at the same time, which is convenient for the post-segment packaging operation. According to the length difference between the normal paper roll and the paper tail, when passing through the conveying inlet with adjustable width, the paper tail automatically falls into the corner material box in the gap between the next process, and the normal paper roll can pass normally because its length reaches 3 times of the paper tail, and enters the next packaging process.

[0024] In the present embodiment, the driving mechanism includes a driving shaft and a driving motor 14. The driving shaft is installed at the bottom end of the first adjusting shaft 9 and passes through the first supporting frame 4. The driving motor 14 is installed on the mounting platform 1.

The first bevel gear 15 is meshed and connected with the second bevel gear 16, so that the first bevel gear 15 can drive the second bevel gear 16 to rotate. The second bevel gear 16 drives the driving shaft to rotate, and the driving shaft drives the first adjusting shaft 9 to rotate.

[0025] In this embodiment, the paper tail dropping mechanism further comprises a drop groove 17, which is provided on the mounting platform 1. The drop groove 17 provided on the mounting platform 1 can facilitate the discharge of paper rolls whose size is smaller than the distance between the connecting belt 13 and the guide rod 3.

[0026] In this solution, the driving motor 14 is a synchronous motor, which has high-precision rotation.
