[0027] A cigarette box missing strip detection device for cigarette packaging, comprising a detection and transmission mechanism 1 and a detection device body 2.

[0028] Specifically, the detection and conveying mechanism 1 includes a conveyor belt 11 and a transmission wheel 12 movably installed at both ends of the conveyor belt 11. Several groups of equally spaced partition seats 111 are fixedly installed on the outer surface of the conveyor belt 11. A smoke box slot 112 is provided between two adjacent groups of the several groups of equally spaced partition seats 111. The detection device body 2 includes a photon tube 21 fixedly installed at one end of the top surface of the detection and conveying mechanism 1 and a photon detector 22 fixedly installed inside the detection and conveying mechanism 1 near the bottom of the photon tube 21. A detector array 221 and a readout chip 222 are fixedly installed inside the photon detector 22 from top to bottom. The outside of the photon detector 22 is electrically connected to a photon counter 23. A smoke box centering mechanism 3 is provided at one end of the detection and conveying mechanism 1. The smoke box centering mechanism 3 includes guide frames 31 symmetrically distributed on both sides of the detection and conveying mechanism 1. The guide frame 31 is composed of a horizontal frame body 32 close to the detection and conveying mechanism 1 and an inclined frame body 33 fixedly connected to the horizontal frame body 32 at one end away from the detection and conveying mechanism 1. The inner walls of the frame 32 and the inclined frame 33 are movably mounted with a plurality of equally spaced displacement wheels 34. During the inspection operation, the cigarette boxes on the conveyor belt of the previous packaging step are continuously moved toward the inspection conveyor mechanism 1, and pass through the inclined frame 33 and the cross frame 32 in turn. The cigarette boxes are displaced and centered in combination with the displacement wheels 34 on the inner wall to ensure that the cigarette boxes are centered on the inspection conveyor mechanism 1, avoid exceeding the range of the detector array, and ensure the accuracy of the inspection data. Finally, the cigarette boxes that need to be packaged and inspected enter the top surface of the cigarette box slot 112 in turn, and successively pass through the top surface of the photon detector 22 under the action of the conveyor belt 11. At the same time, when passing through the top surface of the photon detector 22, the photons emitted by the photon tube 21 have the attenuation characteristic when penetrating an object. The intensity of the photons after penetrating the cigarette box is detected by the photon detector 22 to determine whether there are any missing cigarettes inside the cigarette box. At the same time, the photon counter 23 displays the inspection data intuitively, which facilitates and timely handles the problem of missing cigarette boxes, ensures the overall product quality, and is beneficial to the corporate image of the cigarette factory.

[0029] Preferably, the photon tube 21 includes a tube base 211 and a light-emitting body 212. The light-emitting body 212 is fixedly mounted on the bottom surface of the tube base 211, and the light-emitting body 212 is electrically connected to a fixed power supply and a production control system. A fixing base 2111 is fixedly mounted on both ends of the tube base 211. The fixing base 2111 is fixedly connected to the inner top surface of the fixed frame by fixing screws 2112. A mounting side frame 231 is fixedly mounted on both sides of the photon counter 23. The mounting side frame 231 has a mounting slot 232 extending therethrough. During installation, the fixing base 2111 at both ends of the tube base 211 can be fixedly connected to the inner top surface of the fixed frame by fixing screws 2112, and the mounting side frames 231 on both sides of the photon counter 23 are fixedly connected to the side surface of the transmission frame by screws, thereby achieving fixed installation of the light-emitting body 212 and the photon counter 23.

[0030] Preferably, the photon detector 22 is fixedly mounted between the two inner walls of the conveyor frame by a mounting structure 24. The mounting structure 24 includes a U-shaped frame 241 that is mounted on the bottom surface of the photon detector 22. Both end surfaces of the U-shaped frame 241 are provided with length-adjustable mounting seats 242. The mounting structure 24 can be used to fix the photon detector 22 between the two inner walls of the conveyor frame, and the photon detector 22 is located directly below the bottom of the photon tube 21, which can make photon detection more accurate.

[0031] Preferably, the length-adjustable mounting base 242 includes a fixed cylinder 2421 fixedly mounted on the end surface of the U-shaped frame 241, and the end of the fixed cylinder 2421 away from the U-shaped frame 241 is movably mounted with a movable seat 2423 through a telescopic rod 2422. A locking bolt 2424 is spirally mounted on the outer surface of the movable seat 2423. The telescopic rod 2422 and the movable seat 2423 are slidably connected. The end of the movable seat 2423 close to the inner wall of the conveyor frame is fixedly mounted with a rack mounting plate 24231, and the rack mounting plate 24231 and the inner wall of the conveyor frame are fixedly connected by mounting screws 24232. The U-shaped frame 241 is provided to enable the photon detector to The detector 22 is installed firmly. At the same time, the length-adjustable mounting base 242 can be adjusted according to the distance between the two inner walls of the conveyor rack and then installed. During the adjustment process, the movable seat 2423 is slid away from or close to the fixed cylinder 2421, so that the telescopic rod 2422 is extended and retracted accordingly. After the adjustment is completed, the locking bolt 2424 is rotated to position the movable seat 2423. At the same time, the rack mounting plate 24231 and the inner wall of the conveyor rack are fixedly connected by the mounting screws 24232. In this way, the adjustable installation is achieved, so that the photon detector 22 is suitable for packaging conveyor racks of different widths and sizes, and is highly practical.

[0032] In summary, the present invention can utilize the smoke box centering mechanism to enable the smoke box to be centered on the detection conveyor belt, thereby avoiding exceeding the range of the detector array and ensuring the accuracy of the detection data.
