In view of the current of dry lotus core punching, a vertical multi-station lotus core puncher has been designed and developed. This paper introduces the whole structure and the working of the puncher, and maltese mechanism, positioning and clamping mechanism and space cam mechanism are explained in detail. The results of prototype test indicated that the once punching rate of no less than 92%, the thorough punching rate of no less than 85% and the broken rate of kernels of less than 5%.
