Abstract
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 realizi…
