The present invention provides a system for on-line detecting the package airtightness of cigarette packet, which comprises a first conveyor belt; a plurality of detection box bases arranged on the first conveyor belt at preset intervals, wherein the cigarette packets are sequentially conveyed onto each detection box base; a second conveyor belt arranged above the first conveyor belt, and the central plane of the second conveyor belt being in coincide with the central plane of the first conveyor belt; a plurality of detection box covers arranged on the second conveyor belt at preset intervals, wherein each detection box cover is provided with a slit on one side face, and the detection box cover positioned on the lower end face of the second conveyor belt is cooperated with the detection box base directly below the second conveyor belt during the detection; and a detection probe aligned with the slit during the detection so as to detect the package airtightness of the cigarette packet positioned within the detection box cover through the slit. The detection system can detect the package airtightness of the cigarette packet on line packet by packet at high throughout, thereby realizing on-line quality control.

The present disclosure has provided an automatic multichannel apparatus for assessing hot coal fallout propensity of burning cigarettes and an assessing method thereof. The apparatus comprises a multichannel rotary plate unit, an automatic supplying unit for cigarette samples, an automatic ignition and burning line detection unit for cigarette samples, a cigarette holding and force applying unit, an automatic hot coal fallout detection and removal unit, a smoke collecting unit during suction, a suction unit, a gas exhaust unit arranged in a main frame, and an electric circuit and air path control unit for controlling actions and processes of the above units. The apparatus operates based on certain steps and performs automatic ignition and burning line detection on cigarette samples inserted into a rotary plate in sequence. A controllable external force is applied to the cigarettes during burning and suction, and hot coal fallout propensity of this kind of cigarette is detected by hot coal fallout occurrence of multiple cigarettes. The apparatus according to the present disclosure can improve test repeatability and working efficiency.
