Red jujube pitting machine is an automatic equipment which can pit abundant red jujube quickly. A type of red jujube pitting machine was designed in this study, this type of pitting machine could realize such functions: loading material, location, transportation, pitting, slicing and falling the material, and finally produced edible red jujube sheet. This study had designed the transmission system of the red jujube, and had analyzed the kinematics of the Geneva mechanism in the Pro/E, and improved the motion performance of the Geneva mechanism.
