[0041] Furthermore, the first pushing assembly 35 includes a first support seat 354, which is arranged at the rear end of the belt conveyor 2 on the right side. A first cylinder 355 is arranged in the middle of the upper surface of the first support seat 354, and a push plate 351 is arranged at the front end of the telescopic end of the first cylinder 355.

[0042] Furthermore, the sorting mechanism 3 also includes two photoelectric sensors 36, which are respectively arranged at one end of each belt conveyor 2 close to the belt weighing machine 1, wherein the transmitting end of each photoelectric sensor 36 is respectively arranged on the front side of the belt conveyor 2, and the receiving end of each photoelectric sensor 36 is respectively arranged on the rear side of the belt conveyor 2, and the front and rear positions of the transmitting end and the receiving end of the photoelectric sensor 36 on the belt conveyor 2 on the same side correspond to each other, the input end of the transmitting end of each photoelectric sensor 36 is electrically connected to the output end of the controller 5, and the receiving end of each photoelectric sensor 36 is bidirectionally electrically connected to the controller 5.

[0043] The working principle of the sorting mechanism 3 is as follows: the cigarette strips are transported horizontally to the upper end of the belt conveyor 2 on the left, the limit plate 31 arranges the cigarette strips neatly, and the cigarette strips continue to move forward and are clamped between the two cross baffles 324. The length of the branches of the cross baffles 324 is the same as the width of the cigarette strips. The output shaft of the motor 327 rotates to drive the input shaft 322 to rotate, and the two worms rotate to drive the two worm gears 326 to rotate relative to each other. The two cross baffles 324 rotate relative to each other to deliver the cigarette strips, while blocking the cigarette strips at the rear, thereby realizing the intermittent feeding of the cigarette strips. When a cigarette carton passes through the transmitting end and receiving end of the photoelectric sensor 36, the receiving end of the photoelectric sensor 36 feeds back the position information of the cigarette carton to the controller 5.

When the cigarette carton passes through the transmitting end and receiving end of the photoelectric sensor 36 at the right end, the two cross baffles 324 rotate relative to each other to release the next cigarette carton. After the unqualified cigarette carton passes through the transmitting end and receiving end of the photoelectric sensor 36 at the right end, the telescopic end of the first cylinder 355 pushes out, and the two first slide columns 353 push the push plate 351 forward, and the unqualified cigarette carton is pushed out of the belt conveyor 2 on the right side. Whenever a qualified cigarette carton passes through the transmitting end and receiving end of the photoelectric sensor 36 at the right end, the controller 5 counts, and the unqualified cigarette carton is not counted.

[0045] Further, the baffle 43 is an L-shaped baffle;

[0046] The second pushing assembly 42 includes a linear guide rail 424, which is arranged at the upper end of the bracket 41. A connecting frame 421 is arranged between the slides of the linear guide rail 424. The lower end of the connecting frame 421 is provided with second cylinders 422 that are symmetrically distributed on the left and right. A pushing plate 423 is arranged between the lower ends of the telescopic ends of the two second cylinders 422. The right end of the pushing plate 423 is slidably connected to the left side of the baffle 43. The air inlet of each second cylinder 422 is connected to the air outlet of the external air pump.

[0047] Furthermore, the stacking mechanism 4 also includes a first stacking component 47, which includes a first cylinder seat 472, which is arranged at the left end of the upper surface of the base plate 45, and a third cylinder 471 is arranged at the upper end of the first cylinder seat 472, and a first stacking plate 473 is arranged at the right end of the telescopic end of the third cylinder 471, and the lower end of the first stacking plate 473 is slidably connected to the upper surface of the base plate 45, and the air inlet of the third cylinder 471 is connected to the air outlet of the external air pump.

[0049] The working principle of the stacking mechanism 4 is as follows: the cigarettes move to the right on the right belt conveyor 2 until they contact the baffle plate 43. When the cigarettes accumulate to a set number, the slide of the linear guide 424 drives the connecting frame 421 to move forward, and the second cylinder 422 and the push plate 423 move forward to push the accumulated cigarettes to the upper surface of the bottom plate 45 and keep the cigarettes flush. Then the telescopic end of the second cylinder 422 is retracted, and the slide of the linear guide 424 drives the push plate 423 to reset. After reaching the original position, the second cylinder 422 resets to avoid collision between the push plate 423 and the cigarettes. Then the telescopic end of the third cylinder 471 pushes the first stacking mechanism 421 to move forward. The stacking plate 473 moves to the right to arrange the cigarette cartons closely, the telescopic end of the electric lifting column 46 is retracted, and the bottom plate 45 moves down between the four telescopic columns 44 to keep the upper surface of the cigarette cartons flush with the upper surface of the belt conveyor 2 at the right end. The second layer of cigarette cartons is stacked in the same way. When a sufficient number of layers are stacked, the upper surface of the bottom plate 45 is flush with the lower end of the second stacking plate 481, and the telescopic end of the fourth cylinder 484 is pushed out. The four second sliding columns 483 drive the second stacking plate 481 to move forward and push the stacked cigarette cartons to the next packaging equipment. During this period, the first stacking plate 473 remains pushed out to avoid force dispersion on the stacked cigarette cartons.
