[0029] Two drive motors 9 are fixedly installed on the front side of the frame 2, wherein the output end of one of the drive motors 9 is fixedly connected to one end of one of the drive rollers 5, and the output end of the other drive motor 9 is fixedly connected to one end of the rotating shaft 6. By using the detection camera 4, the drive roller 5, the rotating shaft 6, the conveyor belt 7, the flip plate 8, the drive motor 9 and the guide column 11 in coordination with each other, when inspecting the front and back sides of the cigarette package, only one detection camera 4 is needed to take photos of the front and back sides of the cigarette package, without setting up multiple detection cameras 4, thereby reducing the overall cost of the device.

[0030] The guide assembly includes two fixed plates 10 fixedly connected to the top of the frame 2, one of the fixed plates 10 is provided with a control panel 12 and a controller 13, and the bottoms of the two fixed plates 10 are rotatably connected to a plurality of guide columns 11. When the cigarette packs are transported by the conveyor belt 7, the two sides of the cigarette packs abut against the plurality of guide columns 11. Through the setting of the guide columns 11, the friction force on both sides of the cigarette packs when being transported can be reduced. The tops of the two fixed plates 10 are fixedly connected with a U-shaped frame 14, and the detection camera 4 is fixedly installed at the bottom of the inner wall of the U-shaped frame 14.

[0031] The rejection component includes a connecting plate 16 fixedly connected to the back of the conveying mechanism 3, and an electric telescopic rod 17 is fixedly installed on one side of the connecting plate 16. The telescopic end of the electric telescopic rod 17 is fixedly connected to a push plate 18. The control panel 12 drives the electric telescopic rod 17 to extend its telescopic end, thereby driving the push plate 18 to move, and the defective cigarette packs are directly pushed to one side of the conveying mechanism 3, so that the defective cigarette packs can be pushed into the collection frame 15 for collection and unified processing.

[0032] Working principle: During operation, the cigarette packs to be inspected are placed on the two conveyor belts 7, and the driving motors 9 for driving the two conveyor belts 7 to rotate are started through the control panel 12. Under the action of the two driving rollers 5, the two conveyor belts 7 drive the cigarette packs to be inspected to move, and the cigarette packs are moved to the bottom of the detection camera 4. The detection camera 4 takes a photo of the front of the cigarette pack to detect whether there are defects on the front of the cigarette pack. After taking a photo to detect the front of the cigarette pack, the signal is transmitted to the controller 13, and the controller 13 analyzes the signal and transmits the signal to the control panel 12 at the same time. The control panel 12 starts another driving motor 9 to drive the rotating shaft 6 and the flip plate 8 to rotate. At this time, the cigarette packs are transported to the flip plate 8 under the action of the two conveyor belts 7, and the rotating flip plate 8 flips the cigarette packs under the cooperation of the conveyor belts 7. After the cigarette packs are flipped, the detection camera 4 takes a photo of the back of the cigarette pack again to detect whether there are defects on the back of the cigarette pack, and transmits the signal to the controller 13 again;

[0033] When both the front and back sides of the cigarette package are inspected and both sides are intact, they are conveyed to the conveying mechanism 3 under the action of the guide plate 19 and directly conveyed to the next process. If both the front and back sides of the cigarette package are inspected and one side or both sides are defective, when the cigarette package is moved to the conveying mechanism 3 and transported by the conveying mechanism 3, under the action of the controller 13, the electric telescopic rod 17 is driven through the control panel 12 to extend the telescopic end, thereby driving the push plate 18 to move, and the defective cigarette package is directly pushed to one side of the conveying mechanism 3, so that the defective cigarette package falls into the collection frame 15.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
