Novel high-speed and high-efficiency screw mixing head structure

The utility model provides a novel high-speed high-efficiency screw mixing head structure which comprises a mixing head body, the mixing head body is detachably connected with a screw base body, a plurality of gear type barriers and runner type barriers are uniformly distributed on the mixing head body, and the gear type barriers and the runner type barriers are alternately distributed; the gear type barrier is in a gear shape, a plurality of gear teeth are evenly distributed on the gear type barrier, and a wheel groove between every two adjacent gear teeth is used for allowing materials to flow. The runner type barrier is annular, a plurality of inner runner holes and outer runner holes which are distributed at intervals are uniformly distributed in the runner type barrier, the axes of the outer runner holes are radial, and the outer runner holes are scattered outwards from the axis of the mixing head body; and the axis of the inner runner hole is contracted and converges towards the axis of the mixing head
