The invention discloses a six-axis synchronous stirring and uniformly-mixing device for three-dimensional axial liquid flow generation, and relates to a stirrer. The six-axis synchronous stirring anduniformly-mixing device comprises a top power transmission system control device, a workbench lifting mechanism, a base part, a supporting system and a spiral blade stirring head device; a speed adjusting motor(1) is inverted above the center of a top device shell (16), is linked with a driving gear (2) through a key, and then is connected with synchronous gears (5) above the same transmission shaft through an intermediate gear (3) and a driven gear (4);a toothed transmission belt is connected with the other synchronous gears (5) having the same geometrical parameters and uniformly distributedon the same circumference, and the synchronizing gears are arranged above the top shell (16) of a top transmission system to form a circumferentially uniformly distributed six-axis synchronous transmission system in the same horizontal plane. The six-axis synchronous stirring and uniformly-mixing device adopts a cylindrical coordinate system, so that the stirring device is compact in overall layout structure; through adoption of the speed adjusting motor and a stepless speed adjusting control system, for different mixed solutions, stepless speed adjustment is achieved, so that the best stirring and uniformly-mixing effect is achieved.
