When the in-position sensor arranged next to the lifting fork detects it, the cylinder of the bundling paper tightening device arranged above the bundling support frame will extend toward the bundling paper, and the tensioning suction cup head arranged at the end of the cylinder rod will suck the bundling paper The left side moves so that the strapping paper is in a tensioned state. In this state, the strapping paper cutting device installed just above the lifting fork will drive the mobile platform and the mobile cutting knife installed thereon to descend under the drive of the "D"-shaped driving mechanism to cut the strapping paper, so that the strapping paper is cut off. The strapping paper recovery mechanism installed under the support frame can use the rotating cylinder to drive the arm and the suction nozzle installed at the end to rotate to the gap between the forks of the two forks to suck away the strapping paper. Since the gap between the forks of the two forks is larger than the width of the strapping paper, the strapping paper will not be pressed on the two forks.By arranging a first shaft component and a second shaft component in a mirror-image "D"-shaped drive mechanism, and connecting them through a connecting rod and a sector tooth, a mirror-image "D"-shaped surging trajectory of the lifting fork is synthesized, wherein the first shaft and the second shaft are parallel to each other, and the motor connected to the first shaft through the transmission mechanism can be used to drive the first shaft to rotate. By arranging a coaxial track drum on the edge of the shaft, and arranging an "Ω"-shaped groove track connected end to end on the outer periphery of the track drum, the slider can be driven to move left and right along the axial direction of the second shaft by the connecting rod and the sliding pin during the rotation of the first shaft, and the lifting fork can move left and right to achieve the movement to the same horizontal plane of the conveyor belt of the whole bundle of small box packaging paper and the horizontal exit action from the positioning track. By arranging a lifting gear on the second shaft through a spline shaft, and making the axial rack mesh with the lifting gear, the lifting gear can achieve the purpose of axial sliding and rotating at the same time when the second shaft rotates, and can drive the lifting rod with the axial rack to move up and down during rotation, thereby realizing the lifting and lowering of the lifting fork. By arranging The fan-shaped teeth have a movable pin at the rear end thereof, and the movable pin is caused to move within the deformable ring track of the track disk at the end of the rotating shaft one. During the rotation of the rotating shaft one, the fan-shaped teeth can realize intermittent rotation of the rotating shaft two. The combined movement of the rotating shaft one and the rotating shaft two ultimately realizes mirror-image "D"-shaped trajectory movement, thereby realizing vertical lowering of the load of the upgrading fork, returning when unloaded, horizontally exiting the positioning track after lowering, and returning to the starting position after raising. The lifting fork is repeatedly raised and lowered, and the unbundled cigarette box packaging paper can be continuously sent to the positioning track. The single cigarette box packaging paper suction device can then quickly suck the single cigarette box packaging paper from the positioning track, place it on the single cigarette box packaging paper transmission belt below, and send it to the cigarette box folding production line. By utilizing the present invention, the system can automatically transport bundled cigarette box packaging paper and automatically remove the bundling paper, thereby realizing system automation, reducing the labor intensity of workers, reducing cigarette box packaging paper setting errors, reducing alarm shutdowns, and ensuring smooth production.

Since the gap between the forks of the two forks structure is larger than the width of the strapping paper 72, the strapping paper 72 will not be pressed on the two forks.By arranging the rotating shaft assembly 30 and the rotating shaft assembly 40 in the mirror image "D" shaped drive mechanism and connecting them through the connecting rod 35 and the sector teeth 42, the mirror image "D" shaped surging trajectory of the lifting fork 20 is synthesized. Among them, the rotating shaft 1 30a and the rotating shaft 2 40a, which are parallel to each other, can be driven by the motor 46 connected to the rotating shaft 1 30a through the transmission mechanism. By arranging a coaxial track drum 32 on the edge of the rotating shaft and arranging an "Ω" shaped groove track 33a connected end to end on the outer periphery of the track drum 32, the connecting rod 35 and the sliding pin 33b can be driven during the rotation of the rotating shaft 1 30a. The slider 36 makes different left and right movements along the axial direction of the second rotating shaft 40a, and the lifting fork 20 moves in the left and right directions to realize the movement to the same horizontal plane of the conveyor belt 70 of the whole bundle of small box packaging paper and the horizontal withdrawal movement from the positioning track 80. By setting the lifting gear 37 on the second rotating shaft 40a through the spline shaft and making the axial rack 38b engage with the lifting gear 37, the lifting gear 37 can realize the purpose of axial sliding and rotating while the second rotating shaft 40a rotates. When rotating, it can drive the lifting rod 38 with the axial rack 38b to rise and fall, thereby realizing the lifting and lowering of the lifting fork 20. A sector tooth 42 is provided at the end of the second rotating shaft 40a, and a movable pin 43a is provided at the rear end of the sector tooth 42, and the movable pin 43a is made to move in the deformed ring track 34a of the track plate 34 at the end of the first rotating shaft 30a. The sector tooth 42 can realize the intermittent rotation of the second rotating shaft 40a during the rotation of the first rotating shaft 30a. The combination of the movements of the first rotating shaft 30a and the second rotating shaft 40a finally realizes the mirror image "D" shaped trajectory movement, thereby realizing the vertical lowering of the load of the upgrading fork, returning when empty, horizontally exiting the positioning track 80 after descending, and returning to the starting position after ascending. By repeatedly raising and lowering the lifting fork 20, the lifting fork 20 can be lifted and lowered. The unbundled cigarette box wrappers 71 are continuously fed into the positioning track 80. A single cigarette box wrapper 71 suction device can then quickly suck a single cigarette box wrapper 71 from the positioning track 80, place it on the single cigarette box wrapper conveyor belt 91 below, and feed it to the cigarette box folding production line. By utilizing the present invention, the system can automatically transport bundled cigarette box wrappers 71 and automatically remove the binding paper 72, achieving system automation, reducing worker labor intensity, minimizing cigarette box wrapper 71 placement errors, and reducing alarm shutdowns, thereby ensuring smooth production.
