Abstract:
    The utility model is an extrusion machine for making pet food, provided with a machine frame fixedly installed with a cylinder body, a decelerator and a regulating motor; a mould head is installed on the one end of the cylinder body. It is characterized in that: the inner wall of the cylinder body is processed and equipped with many axial notches; a screw with various pitches is slide key connected with an output shaft of the decelerator in the cylinder. During the extrusion machine for making pet food of the utility model is working, the screw and the axial notches on the inner wall of the cylinder strongly knead the material and push it forward, to make the material high speed extruded from the mould head to form the pet food. Because the screw is the various pitches screw, the utility model can increase largely the compactness of the pet food extruded.
