The present invention provides a device for detecting the lack of packs in a strip box. A pulse generating mechanism and a switch detecting mechanism are both arranged on a strip box conveying mechanism. The pulse generating mechanism generates continuous pulses and sends them to the strip box. The switch detecting mechanism scans the internal cigarette packs of the strip box during the movement of the strip box. The signal is input into a controller. The controller performs an AND operation on the rising edge signal of each pulse and the cigarette pack detection signal. If the cigarette pack detection signal has a low level within the pulse signal interval, it is displayed as a lack of packs, and the missing cigarette strips are rejected at the rejection station. The device is used to detect the cigarette packs below the strip box, and the pulse generating mechanism and the switch detecting mechanism are used to detect the cigarette packs in the lower layer of the strip box passing through the packaging machine. A strip box is divided into several detection pulses. If the signal is at a low level within the pulse signal interval, it is displayed as a lack of packs. If the pulse signal interval is high level, there is no lack of packs, thereby eliminating the problem of missed detection due to lack of cigarette packs in the lower layer, cigarette packs crossing positions, or cigarette packs lying sideways.
