Novel double-rotating grinding knife for soymilk machine and working method thereof

The invention discloses a novel double-rotating grinding knife for a soymilk machine and a working method of the novel double-rotating grinding knife for the soymilk machine. The grinding speed, efficiency, energy conservation performance and product taste of a current soymilk machine all need to be improved. The top of a bracket of the novel double-rotating grinding knife for the soymilk machineis in thread connection with a cover cylinder; a secondary knife is supported outside the bracket through a thrust ball bearing; a transition gear is fixed at the bottom of the bracket and supported on a partition; a gear ring is in interference fit with the inner wall of the secondary knife; two sides of the transition gear are respectively meshed with a driving gear and the gear ring; a main knife shaft penetrates through the cover cylinder, the bracket, the driving gear, the partition and the secondary knife, and three or more main blades are fixed at the bottom end of the main knife shaft.An external motor drives
