The second sensing assembly of the embodiment can be used for removing other defects, such as frame paper or label paper, besides removing the tobacco bale containing the lining paper splicing joint, the second sensor can monitor whether the frame paper or label paper has defects at the same time, if so, the third removing device can directly remove the tobacco bale containing the frame paper or label paper defects after the second sensor monitors the defect marks, and the second sensor can be selected from a camera image recognition sensor, a color sensor, an infrared sensor or an ultrasonic sensor and the like selected in the prior art; or when the frame paper roll needs to be replaced, the second sensor can control the reset switch to turn off the power supply, and after the manual replacement, the third removing device removes the cigarette packet containing the frame paper defect.

The third removing device in the utility model is a device for removing tobacco packages commonly used by a person skilled in the art, and can be selected from removing devices in the prior art, for example, defective tobacco packages are blown into a collecting hopper from a track through blowing, for example, a reciprocating push-pull rod is arranged, when the defective tobacco packages reach a designated position, the push-pull rod pushes the tobacco packages into the collecting hopper from the track, for example, a mechanical claw or a sucker is arranged, when the defective tobacco packages reach the designated position, the mechanical claw or the sucker sends the tobacco packages from the track to the hopper, and the like, and the person skilled in the art can select a proper third removing device according to production requirements.

Although the present utility model has been described in detail by way of preferred embodiments with reference to the accompanying drawings, the present utility model is not limited thereto. Various equivalent modifications and substitutions may be made in the embodiments of the present utility model by those skilled in the art without departing from the spirit and scope of the present utility model, and it is intended that all such modifications and substitutions be within the scope of the present utility model/be within the scope of the present utility model as defined by the appended claims.
