[0023] The working principle is as follows: the utility model can control the extrusion roller to process different materials according to the needs of production materials, and the operation is convenient. Before use, the parameters are set according to the material requirements through the control panel 3, and then the hydraulic pusher 5 is controlled to start working, and the moving plate 6 is pushed to move along the inner wall of the sliding groove 7, thereby driving one of the rotating shafts 8 and the shaping roller 9 to move with the moving plate 6.
