Flexible wheel clamping material automatic centering mechanism

The utility model discloses an automatic centering mechanism for materials clamped by flexible wheels, which comprises a first driving mechanism and two rows of first flexible rollers which are arranged up and down and are correspondingly matched with each other, and a first positioning groove matched with lotus seeds is formed between two adjacent first flexible rollers in each row of first flexible rollers. The first driving mechanism can drive the first positioning groove in the upper portion to be matched with the first positioning groove in the lower portion so as to automatically take and clamp materials. A lotus seed is positioned and clamped by adopting the four first flexible rollers, the lotus seeds with different sizes can be automatically centered by extruding the corresponding first flexible rollers, the lotus plumule of the lotus seed is always consistent with the clamping center of the four first flexible rollers, the precision is high, the efficiency is high, the lotus seed is not easy to dama
