Special-shaped cigarette packet detection device for rotary transmission channel of cigarette packer

The utility model relates to the field of cigarette packaging machinery, in particular to a special-shaped cigarette packet detection device for a rotary transmission channel of a cigarette packaging machine, which is characterized in that a limiting pressing plate on the rotary transmission channel of equipment is modified, an inlet of the limiting pressing plate of a packaging channel is improved, and a detection plate positioned by a spring and a limiting nut is added. When the special-shaped tobacco bales pass through the rotary transmission channel, the detection plate is jacked up by the special-shaped tobacco bales, and the detector is triggered to send out a shutdown signal to enable the equipment to be shut down. According to the special-shaped cigarette packet detection device, the detection of the special-shaped cigarette packets is added while the cigarette packet transmission space is limited, shutdown can be realized after the special-shaped cigarette packets are detected, the situation that the
