When the fruit is at the pitting station, the vertically fixed pitting cylinder drives the pitting knife to move downward, and the pitting knife contacts the fruit pit and continues to move downward until the pit is pushed out of the positioning hole to realize the pitting operation. At this time, only the shell and the pulp are left in the flexible positioning hole; then, the peeling cylinder drives the peeling knife to move upwards, and the peeling knife is held up after contacting the fruit shell. Therefore, when the fruit shell is blocked after being in contact with the baffle plate, the stroke of the peeling cylinder is designed to be fixed at 50 mm, and the stroke of the peeling knife will not exceed the shell-meat separation baffle plate, thereby ensuring that the fruit shell will not exceed the shell-meat separation baffle plate. Due to its flexibility, the pulp is extruded from the flower-shaped hole under the extrusion of the peeling knife to realize the separation operation of the shell and the pulp. Finally, the lantern-shaped pulp that has been de-cored and peeled is taken to the collection box by the pulp collection mechanism.

Further, in order to push the pulp in a directional manner and prevent the pulp from falling from other places of the baffle, ribs are provided on both sides of the baffle, and the baffle and the rib together constitute a channel for pushing by the push rod.
