The first sliding rail 321 is arranged on both sides of the stacking frame 31. The material limiting plate 322 is fixedly connected with sliding blocks of the first sliding rails 321 on both sides. The transmission belts 323 are arranged below the first sliding rails 321 on both sides respectively. The transmission belts 323 on both sides are fixedly connected with both ends of the material limiting plate 322 in linkage. The material limiting motor 324 is arranged on the stacking frame 31 opposite to the feeding mechanism 2.

[0033] The material limiting assembly 32 drives the first transmission rod 325 to rotate through the material limiting motor 324. The first transmission rod 325 drives the transmission belts 323 on both ends in synchronization. Since the transmission belts 323 are fixedly connected with the material limiting plate 322, the material limiting plate 322 moves under the dragging of the transmission belts 323. The synchronous movement of both ends ensures the stable movement of the material limiting plate 322. The servo motor can accurately control the displacement length.

[0034] Further, the discharging assembly 33 of the stacking mechanism 3 is provided with a discharging motor 331, a second transmission rod 332, a second sliding rail 333 and a discharge bin door 334.

The chute 3342 is arranged on the upper surface of the discharge plate 3341 and is perpendicular to the second sliding rail 333. The eccentric rotating rod 3343 is vertically arranged on the stacking frame 31 above the chute 3342. The upper end of the eccentric rotating rod 3343 is connected with the second transmission rod 332 through the bevel gear set 3344. The lower end of the eccentric rotating rod 3343 is eccentrically connected with the chute 3342. The discharging motor 331 is connected with the second transmission rod 332 through a speed reducer.

[0035] The discharge bin door 334 is opened and closed in synchronization under the action of the second transmission rod 332 driven by the discharging motor 331. The discharge bin door 334 is connected with the eccentric rotating rod 3343 through the chute 3342 on the discharge plate 3341. The opening and closing of the discharge plate 3341 can be realized through the rotation of the eccentric rotating rod 3343. The opening and closing of the discharge plate 3341 does not need to be realized through the forward and reverse rotation of the motor.

[0036] Further, the eccentric rotating rod 3343 is an "L" rotating rod, and the lower end of the "L" rotating rod is provided with a roller arranged in the sliding groove 3342. The "L" rotating rod can realize greater opening and closing degree.

[0038] The switching assembly 35 realizes quick switching of the lifting assembly 34 and improves the cooperation degree between various mechanisms. The buffer space 354 can be a rubber pad or a spring to avoid the switching plate 253 from colliding with the rack 1.

[0039] Further, the lifting assembly 34 of the stacking mechanism 3 is provided with a lifting plate 341, a lead screw 342, an internal threaded bearing 343, a guide rod 344, a belt 345 and a lifting motor 346. The internal threaded bearing 343 is arranged on the switching plate 352 of the switching assembly 35. The lead screw 342 is vertically arranged through the internal threaded bearing 343.

[0040] The lifting assembly 34 adjusts the height through the cooperation of the lead screw 342 and the internal threaded bearing 343. The internal threaded bearing 343 is driven by the belt 345 and controlled by the servo motor to control the number of rotation circles, so as to accurately control the lifting height of the lead screw 342 to meet the lifting requirements of different cigarettes. Through the cooperation of the double stations, the efficiency and the accuracy are simultaneously improved. The lifting assembly 34 is provided with a sensing switch to limit the highest and lowest lifting height.

[0041] Further, the feeding mechanism 2 of the stacking mechanism 3 is provided with a feeding conveyor belt 21 and a limiting rod 22. The limiting rod 22 is arranged on both sides of the feeding conveyor belt 21. The limiting rod 22 is arranged in double layers. The relative distance of the limiting rod 22 is adjustable. The distance of the upper limiting rod 22 is smaller than that of the lower limiting rod 22. The discharging conveyor belt 6 is provided with a spacing plate 61.

[0042] Further, the material blocking mechanism 4 is provided with a material blocking cylinder 41 and a material blocking plate 42, the material blocking cylinder 41 is arranged above the inlet of the stacking frame 31 of the stacking mechanism 3, and the material blocking plate 42 is connected with the material blocking cylinder 41.

[0043] Further, the discharging conveyor belt 6 is provided with the feeding mechanism 2, the stacking mechanism 3 and the feeding cylinder 5 on opposite sides, and the lifting assemblies 34 of the stacking mechanisms 3 and the feeding cylinders 5 are distributed in a staggered manner.

[0044] By arranging the stacking mechanism 3 and the feeding cylinder 5 on both sides of the discharging conveyor belt 6, the conveying speed and the stacking speed are matched to be consistent, the stacking efficiency is maximized, and the problem of too long conveying line is avoided.

[0045] Further, the end of the discharging conveyor belt 6 is provided with a discharging cylinder 62 and a film wrapping machine 63 or a boxing machine, and the discharging cylinder 62 and the film wrapping machine 63 or the boxing machine are arranged on opposite sides of the discharging conveyor belt 6.

[0046] It is felt that the stacked cigarettes need to be wrapped with heat-shrinkable film or boxed and then distributed.

[0047] When the equipment is working, the front-end equipment first optimizes and calculates the stacking order of the cigarettes according to the order of each customer, arranges the cigarettes of the same specification in the same layer as much as possible, arranges the cigarettes of similar specifications in the same layer, arranges the cigarettes with large volume in the lower layer, then conveys the cigarettes to the feeding mechanism 2 according to the stacking order, and then sends the cigarettes to the stacking mechanism 3 through the feeding mechanism 2; the stacking mechanism 3 controls the forward distance of the material limiting motor 324 according to the width information of the first layer of cigarettes, so that the stacking frame 31 can just arrange the space for the corresponding number of cigarettes; after the first layer of cigarettes is conveyed, the material blocking mechanism 4 lowers the blocking material; then the unloading motor 331 starts to open the unloading plate 3341, and the cigarettes fall onto the lifting plate 341 below; then the lifting plate 341 controls the lifting motor 346 to lower by the corresponding height according to the height information of the layer of cigarettes; the unloading plate 3341 is closed, the material limiting motor 324 adjusts the forward distance according to the second layer of cigarette information, and the blocking plate is opened to stack the second layer of cigarettes; the above process is repeated to realize multi-layer stacking until the order of the customer is completed or the maximum stacking height is reached. After the stacking is completed, the switching cylinder 353 is actuated to push the stacked cigarettes to the feeding cylinder 5 station, push the stacked cigarettes to the discharging conveyor belt 6, and reset the lifting mechanism; the other lifting assembly 34 station is switched to the stacking station below the unloading assembly 33 to perform the stacking work; thus, the continuity of the stacking work is realized without waiting for discharging and resetting. Finally, the stacked cigarettes are conveyed to the next packaging process.

[0048] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
