The auxiliary packing machine is provided with an on-board transverse conveying belt which is connected with an outlet of the down-slide channel and a lifting mechanism, wherein a cigarette pulling mechanism is arranged above the lifting mechanism; a pulling block is jointed with the rear side of the lifted cigarette packet; a joint cycle of the pulling block and the lifted cigarette packet is synchronous with a reciprocating cycle of the cigarette packet lifting mechanism. A conveying mode of vertically lying and longitudinally arraying of the cigarette packets is changed into a conveying mode of transversely lying so as to avoid the hitting of both ends of the cigarette packet during conveying. After entering the auxiliary machine, the cigarette packets are conveyed by the on-board transverse conveying belt, thus, the cigarette packets transversely enter a cigarette pressing mechanism of the auxiliary machine so as to avoid the hitting of one end of the cigarette packet with a positioning plate. The invention can thoroughly avoid the defects of 'empty ends' and interconnection of the cigarettes.
