A multi-staged screw structure of an extruding machine with additional diffluence and conflux functions. It comprises a lower screw assembly, an outer screw assembly and an inner screw assembly, which are located in the lower mixing chamber (24) and the connecting upper mixing chamber (23). Said lower screw assembly comprises identically structured first main screw (41a) and second main screw (41b), which mesh mutually and contra-rotate in the lower mixing chamber (24). Said outer screw assembly comprising identically structured first auxiliary screw (42a) and second auxiliary screw (42b) and, set in between, the inner screw assembly are arranged in the upper mixing chamber (23). Said inner screw assembly comprises identically structured first compensatory screw (43a) and second compensatory screw (43b), both are located between screws of outer screw assembly and in the upper mixing chamber (23). Said multi-staged screw structure of extruding machine is capable of enhancing the diffluence and conflux of mixture so as to realize a better mixing. |
