The invention relates to a double-knife continuous cutting device for a honeycomb ceramic dry green body, which comprises a green body spring clamping plate, elastic clamps, a conveying track, a positioning slideway and an automatic dedusting device, wherein the spring clamping plate is fixed on the elastic clamps, and 10-32 elastic clamps are connected into the closed conveying track through dowel pins; the closed track can move under the drive action of a pentagonal rolling body and a speed-regulating motor, and the positioning slideway is positioned in the double-knife cutting position of the green body; the automatic dedusting device is arranged behind the cutting position, and the automatic dedusting device comprises a dedusting cover, an air inlet hole, an air blowing pipe, a dust suction port and an external deduster; and compressed air is connected with the air inlet hole and the air blowing pipe through a pipeline to blow off dust, and the dust suction port is further connected with the external deduster. The double-knife cutting device adopts a double-knife structure to enable two ends of the green body to be synchronously cut, and the precision is high; the automatic dedusting device comprises the dedusting cover, the dust suction port, the air inlet hole and the external deduster, thereby removing the dust generated in the cutting process and simultaneously completing dust suction and blowing off of the dust; and the control system is mainly used for controlling cutting and the transmission speed of the track, and the operation is simple and convenient.
