Rotation speed self-adaptive roller mechanism

The utility model discloses a rotating speed self-adaptive roller mechanism which comprises a rack, an upper roller and a lower roller are rotationally connected to the rack, the upper roller is close to the lower roller, and a gap is reserved between the upper roller and the lower roller; a first driving mechanism is fixedly connected to the machine frame and drives the lower roller to rotate, a second driving mechanism is fixedly connected to the machine frame, a magnetic powder type clutch is arranged on one side of the second driving mechanism, the second driving mechanism drives the upper roller through the magnetic powder type clutch, and the magnetic powder type clutch is used for adjusting the rotating speed of the upper roller. And the rotating direction of the upper roller is opposite to that of the lower roller. According to the rotating speed self-adaptive roller mechanism, the second driving mechanism drives the upper roller through the magnetic powder type clutch, and the magnetic powder type cl
