A belt 11 is wound between the conveying mechanism 2 and the first transmission wheel 7. The conveying mechanism 2 transmits the rotation to the first transmission wheel 7 through the belt 11. The rotation of the first transmission wheel 7 drives the adjacent conveying mechanism 2 to rotate. Finally, all the conveying mechanisms 2 rotate, thereby driving the round rod material 3 placed on the conveying mechanism 2 to be transported axially. The utility model is also equipped with a tensioning mechanism 6, through which the tension of the belt 11 can be adjusted to adjust the transmission efficiency of the belt 11.

The first transmission shaft 22 is rotatably connected to the two first mounting plates 21. The transmission wheel 23 is fixed on the first transmission shaft 22 and is located between the two first mounting plates 21. The first transmission shaft 22 needs to be arranged horizontally, so that the transmission wheel 23 is also horizontal after being arranged on the first transmission shaft 22. The round bar material 3 can be arranged on the transmission wheel 23 to ensure stability. The second transmission wheel 24 is fixed at one end of the first transmission shaft 22, and the second transmission wheel 24 is connected to the adjacent first transmission wheel 7 through the belt 11. The output end of the driving motor 8 is connected to any first transmission shaft 22 to drive the first transmission shaft 22 to rotate. The rotation of the first transmission shaft 22 drives the second transmission wheel 24 to rotate, and the first transmission wheel 7 is driven to rotate through the belt 11. The rotation of the first transmission wheel 7 drives the adjacent second transmission wheel 24, and then drives the adjacent first transmission shaft 22 to rotate. Finally, all the transmission mechanisms 2 can rotate.
