[0024] The rotation of the bidirectional threaded rod 3 drives the movement of the bearing seat 5 threadedly connected to the outer side of the bidirectional threaded rod 3, and since the bearing seat 5 is rotatably connected to the two ends of the roller 4, the movement of the bearing seat 5 drives the lifting adjustment of the roller 4 to adapt to the passage of materials of different thicknesses.

[0025] During the rolling process, the material will vibrate when passing through the roller 4. In order to suppress this vibration, the base 1 will be buffered and damped by the elastic action of the adapter block 8 and the spring 9, thereby reducing the influence of the vibration on the device and the material.
