The invention discloses a device capable of improving the sundry removing efficiency of a tobacco sundry removing machine. The device is mainly composed of a vibrating conveyer, a star roller conveyor and a tobacco sundry removing machine sequentially. The star roller conveyor comprises wheel rollers which are arranged at intervals and a conveying bottom band arranged under the wheel roller, wherein the first wheel roller in the wheel rollers is a round roller, and the rest are star rollers. A horizontal tobacco block removing belt conveyor is arranged at the discharge end of the last wheel roller of the star roller conveyor. The conveying bottom band of the star roller conveyor comprises the discharge end connected with a vibrating tank of the vibrating conveyor and the feed end connected with the tobacco sundry removing machine. The width of a conveying section and the width of the vibrating conveyor are larger than or equal to the effective width of the tobacco sundry removing machine, and the width of the discharge section is smaller than or equal to the effective width of the tobacco sundry removing machine. The device effectively improves the sundry removing efficiency and the sundry removing capability of the sundry removing machine.
