The invention discloses a cigarette receiving channel for single cigarette detecting and eliminating equipment of a packaging machine, belonging to the technical field of cigarette packaging machines. The cigarette receiving channel comprises a cigarette transmission channel, a lower roller wheel, a blocking mechanism and end part baffle plates, wherein the lower roller wheel is arranged in the cigarette transmission channel one end of a conveying belt of the cigarette transmission channel is arranged close to a cigarette inlet end the tail end of the conveying belt is provided with a lowerroller wheel connected with a second servo motor the highest point of the lower roller wheel and the upper surface of the conveying belt are positioned on the same plane the blocking mechanism is arranged between two side plates of the cigarette transmission channel and the end part baffle plates are arranged on two side plates of the cigarette transmission channel. During working, the inlet of the cigarette transmission channel is connected with the die box eliminating position of the packaging machine, and the blocking mechanism and the lower roller wheel co-act after an eliminated cigarette passes through the cigarette transmission channel, so that a cigarette which is possibly hung between the cigarette transmission channel and a cigarette falling port is conveyed to a cigarette falling port position. Due to the adoption of the cigarette receiving channel, eliminated cigarettes can be collected orderly, and the phenomena of cigarette blockage and disarrangement caused by continuous elimination are avoided.
