[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] like Figure 1-Figure 7 As shown, the present invention provides a technical solution: a cigarette sorting device and a sorting method thereof, comprising a mounting frame 1 and a sorting conveyor belt 2, the sorting conveyor belt 2 being located at the bottom of the mounting frame 1 and being used to convey cigarettes, which are conveyed to the bottom of a coding machine via the sorting conveyor belt 2, and the coding machine subsequently codes and sorts the cigarettes, a cigarette storage bin 3 is fixed on one side of the top of the mounting frame 1, a special-shaped partition 4 is fixed in the cigarette storage bin 3, and material cavities are formed on both sides of the special-shaped partition 4, it can be known that the material cavity is located directly above the sorting conveyor belt 2, and the cigarettes fall directly above the sorting conveyor belt 2 through the material cavity, wherein the material cavity comprises a rectangular channel 401 and a material channel, in order not to increase the height of the cigarette storage bin 3, thereby reducing the volume of the device and reducing the occupied plant space, the width of the material channel gradually increases from bottom to top;

[0046] There are multiple buffer components on both sides of the material channel to block the cigarettes, such as Figure 2 As shown, the buffer assembly includes a fixed shaft 501, an arc groove 503 and a connecting shaft 605. The buffer plate 502 is movably connected to the shaft body of the fixed shaft 501. Figure 7 As shown, a slide groove is provided on the side of the buffer plate 502, and a slider is fixed to the end of the connecting shaft 605. The slider is adapted to the slide groove, and the connecting shaft 605 is located in the arc groove 503. The buffer plate 502 rotates under the drive of the connecting shaft 605. In a specific embodiment of this solution, in order to avoid collision between the cigarette strips and the buffer plate 502 during loading, the buffer plate 502 is preferably a rubber plate.

[0047] like Figure 1 and Figure 4 As shown, a rotating assembly 6 is provided on the outer side of the connecting shaft 605, and a power assembly 7 is provided between the two rotating assemblies 6;

[0048] It can be seen that the connecting shaft 605 is driven by the power assembly 7 to reciprocate in the arc groove 503, thereby preventing the cigarette rods in the material chamber from being blocked.

[0049] An installation groove is provided at the bottom of the special-shaped partition 4, and a smoke outlet mechanism 9 is provided in the installation groove. The smoke outlet mechanism 9 includes a bottom smoke blocking component and a side smoke blocking component. It can be understood that the smoke blocking component blocks the cigarette strips at the bottom, and the side smoke blocking component squeezes the cigarette strips on the top of the bottom cigarette strips laterally, so that the cigarette strips on top are fixed when the bottom cigarette strips are discharged, avoiding continuous unloading and causing the cigarette strips to pile up in a disorderly manner on the sorting conveyor belt 2, which is convenient for subsequent coding and sorting.

[0050] like Figure 6 and Figure 7 As shown, the bottom smoke shield assembly includes two bottom shields 901 movably connected to the special-shaped partition 4, a bottom plate 903 and a second motor.

A third hinge plate is movably connected between the two second vertical axes. It can be known that the top plate 904 is fixed to the roller.

[0055] The controller controls the second motor to start, and the second motor drives the roller to rotate, so that the bottom baffle 901 and the side baffle 902 are alternately extended and retracted, so that the cigarettes fall regularly (equidistantly) to the top of the sorting conveyor belt 2.

[0056] like Figure 4 and Figure 5 As shown, the rotating assembly 6 includes an L-shaped plate 601, the plate body of the L-shaped plate 601 is rollingly connected to the first rotating shaft, and the first rotating wheel 602 and the second rotating wheel 603 are respectively fixed to the shaft bodies on both sides of the first rotating shaft;

[0057] A third vertical shaft is fixed at a non-center position of the first rotating wheel 602, a first hinge plate 606 is movably connected between the third vertical shaft and the connecting shaft 605, and a belt 604 is connected between the wheel bodies of several second rotating wheels 603. In this solution, the number of buffer plates 502 on each side is set to three.

[0058] like Figure 4 As shown, the power assembly 7 includes a first gear 703 fixed on the innermost first rotating shaft, a U-shaped frame 701 fixed to the side of the cigarette storage chamber 3, and a first motor 702. The U-shaped frame 701 is rollingly connected to the second rotating shaft, the output end of the first motor 702 is fixed to the end of the second rotating shaft, and a second gear is fixed to the shaft body of the second rotating shaft, and the second gear is respectively engaged with the two first gears 703.

[0059] In this way, the controller controls the first motor 702 to start, and when the first motor 702 rotates, it drives the second gear to rotate, and the second gear drives the two first gears 703 to rotate. When the first gear 703 rotates, the corresponding second rotating wheel 603 rotates, and finally the belt 604 drives the remaining second rotating wheels 603 to rotate and the first rotating wheel 602 to rotate;

[0060] When the first rotating wheel 602 rotates, it drives the buffer plate 502 to move up and down around the fixed shaft 501 to prevent cigarettes from piling up on the top of the buffer plate 502 .

[0061] To tension the belt 604, Figure 4 As shown, a tensioning assembly 8 is provided between the two belts 604 .

[0062] The tensioning assembly 8 includes a V-shaped plate 801 and an electric telescopic rod 803;

[0067] Step 3: Start the first motor 702 and the second motor. When the second motor is started, it drives the bottom baffle 901 to retract into the installation slot. At this time, the side baffle 902 moves out of the installation slot. The cigarettes at the bottom of the two rectangular channels 401 fall onto the sorting conveyor belt 2. At this time, the side baffle 902 clamps the cigarettes at the top of the rectangular channels 401. The cigarettes that fall onto the sorting conveyor belt 2 are conveyed by the sorting conveyor belt 2. When the first motor 702 is started, it drives the buffer plate 502 to move up and down around the fixed axis 501 to prevent the cigarettes from piling up on the top of the buffer plate 502.

[0068] Step 4: The cigarette strips transported by the sorting conveyor belt 2 are coded by a coding machine and then sorted;
