The invention relates to a wood block shaping device, in particular to a wood block shaping device for a rolling pin. The wood block shaping device for the rolling pin can realize integration of automatic feeding, automatic shaping and automatic receiving. The wood block shaping device for the rolling pin comprises a bottom plate, a motor, a rotating mechanism and a transmission mechanism, whereina motor base is arranged in the middle of the bottom plate; the motor is mounted at the top of the motor base; one side, close to the motor base, of the bottom plate is provided with the rotating mechanism used for shaping a rolling pin wood block, and the rotating mechanism is connected with an output shaft of the motor; and the transmission mechanism used for conveying long-strip-shaped wood blocks is arranged in the middle of the bottom plate, and the transmission mechanism is connected with the end, away from the rotating mechanism, of the output shaft of the motor. According to the device, a first rotating shaft rotates to drive a large gear to rotate, so that a small gear is driven to rotate, then a shaping opening rotates, and the effect of shaping the wood block moving into the small gear is achieved.
