s2, starting the double-shaft high-speed dispersing device body (1), enabling two dispersing shafts (2) to rotate, simultaneously selectively starting one mixing axial dispersing mechanism (3), or simultaneously starting two mixing axial dispersing mechanisms (3), when the mixing axial dispersing mechanisms (3) are started, starting the telescopic cylinders (106) in two semi-dispersing mechanisms, enabling telescopic ends of the telescopic cylinders (106) to perform telescopic movement, driving the driving racks (105) to longitudinally slide and lift in the sliding sleeve (111) through the connecting rods (107), enabling meshing of the driving racks (105) and the adjusting gears (103) to drive the adjusting gears (103) to rotate by taking the circle center of the transverse shaft (102) as the circle center, enabling meshing of the adjusting gears (103) and the stabilizing racks (108) to drive the stabilizing racks (108) to longitudinally slide and lift in the other sliding sleeve (111), and enabling the adjusting gears (103) to drive the dispersing racks (105) to drive the semi-oscillating disc (101) to reciprocate between the driving racks (105) and the stabilizing racks (108);
s3, when initial telescopic states of the two telescopic cylinders (106) in the two half-dispersing mechanisms are consistent, the two half-dispersing plates (101) perform crossed swinging motion, and when initial telescopic states of the two telescopic cylinders (106) in the two half-dispersing mechanisms are opposite, the two half-dispersing plates (101) perform homodromous swinging motion.
