Cylinders 2 12 are installed on both sides of the support base 1. A sleeve 13 is sleeved on the rotating roller 4 11. The output end of cylinder 2 12 is connected to the sleeve 13. Specifically, starting cylinder 2 12 can drive the sleeve 13 to move. Since the sleeve 13 is sleeved on the rotating roller 4 11 and is connected to the rotating roller 4 11, it is a rotating roller 4 10. The 11 movable connection allows the sleeve 13 to move and drive the rotating roller 4 11 to move, facilitating the adjustment of the distance between the rotating roller 3 10 and the rotating roller 4 11; the inner bottom of the support base 1 is equipped with a drive motor 2 14, the output end of the drive motor 2 14 is movably connected to the rotating roller 1 2, the leveling roller 3, the rotating roller 3 10 and the rotating roller 4 11 respectively.
