The rotating shaft of the driving motor 21 is used to drive the driving shaft 6 to rotate, and the driving shaft 6 drives the active roller 7 to rotate. The driving gear 8 follows the rotation of the driving shaft 6 and meshes with any driven gear, and then drives the driven shaft 3 and the driven roller 4 to rotate through the driven gear 10. A driving gear 8 is arranged on the driving shaft 6 outside the middle support frame 5, a sleeve 9 is slidably arranged on the driven shaft 3 above the driving gear 8, a driven gear set 10 is fixedly mounted on the sleeve 9, and the driven gear set 10 reciprocates along the driven shaft 3 with the sleeve 9; the driven gear set 10 includes a plurality of driven gears coaxially arranged in descending order of nominal diameter, the driving gear 8 is meshed with any driven gear in the driven gear set 10, and the replacement assembly is installed at the position of the driven gear set 10, and is used to adjust the position of the driven gear set 10 meshed with the driving gear 8;
