PURPOSE:To enable high or low kneading effect to be selected by one machine and to feed directly raw material to a kneading part, if necessary, by housing the planetary shaft for kneading in a receiving chamber. CONSTITUTION:The receiving chamber 27 like a cylindrical shaft whose inner wall is lapped by one part over a screw shaft 3 is formed capably of opening and closing by an upper movable block 33 and a lower fixed block 20. In said chamber 27, the kneading planetary shaft 22 which is graved like the shape of a gear engaging the kneading gear of the screw shaft and the flat surface shaft 28 which closed the receiving chamber and has the formed flat surface allowing the rotation of the screw shaft at the side of the screw shaft, are received capably of selecting freely. Accordingly, the high grade kneading by using two planetary shafts 22 for kneading, the medium grade kneading by using a planetary shaft for kneading and a flat surface shaft and non kneading by using two flat surface shafts, may be achieved. |
