[0033] In actual application, the cut tobacco falls into the tobacco falling groove 5 through the outlet of the GD121A cigarette making machine rough roller material bin. If the cut tobacco stacking posture monitoring element 6 arranged on the inner wall of the GD121A cigarette making machine rough roller material bin tobacco falling groove detects that the cut tobacco stacking near the first air blowing element 2 is too high, the cut tobacco stacking posture monitoring element 6 controls the first air blowing element 2 to open through the PLC controller, and the first air blowing element 2 blows air to the cut tobacco stacking near the first air blowing element 2, so that the cut tobacco on the side with higher cut tobacco stacking or more cut tobacco falls to the cut tobacco on the side with higher cut tobacco stacking or more cut tobacco, so that the cut tobacco falling into the tobacco falling groove 5 is in a generally flat state.

[0034] It should be noted that the tobacco falling port 4 and the tobacco falling groove 5 are both on the GD121A cigarette making machine rough roller material bin, wherein the tobacco falling port 4 is located in the tobacco falling groove 5, and the tobacco falling port 4 and the tobacco falling groove 5 are the existing structures on the GD121A cigarette making machine rough roller material bin.

[0035] Please refer to Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 , the first air blowing element 2 and the second air blowing element 3 for blowing the cut tobacco falling into the tobacco falling groove 5 to be flat are air blowing elements of the same structure, which include an air nozzle 7 and an air pipe 8, wherein the air nozzle 7 is used for blowing the cut tobacco falling into the tobacco falling groove 5 to be flat, and the air pipe 8 is used for supplying air to the air nozzle 7.

[0037] In actual application, when the first air blowing element 2 blows air to the cut tobacco stacked near the first air blowing element 2, the air pipe 8 in the first air blowing element 2 supplies air to the air nozzle 7, the air entering the air nozzle 7 is blown to the cut tobacco stacked near the first air blowing element 2 through the air blowing end of the air nozzle 7, so that part of the cut tobacco falls to the cut tobacco stacked on the other side, and the cut tobacco falling into the tobacco falling groove 5 tends to be in a generally flat state.

[0038] When the second blowing member 3 blows the tobacco close to the second blowing member 3, the air pipe 8 in the second blowing member 3 supplies air to the air nozzle 7, the air entering the air nozzle 7 is blown to the tobacco close to the second blowing member 3 through the air blowing end of the air nozzle 7, so that part of the tobacco falls on the tobacco on the other side, and the tobacco falling into the tobacco falling groove 5 tends to be in a generally flat state.

[0039] Please refer to Figure 4 , Figure 5 , Figure 7 and Figure 8 , the first blowing member 2 and the second blowing member 3 for blowing the tobacco falling into the tobacco falling groove 5 to be flat also include a micro air pump and a solenoid valve; wherein the micro air pump is used to supply air to the air nozzles 7 in the first blowing member 2 and the second blowing member 3 through the air pipes 8; and the solenoid valve is used to terminate or open the process of supplying air to the air nozzles 7.

[0040] Specifically, the micro air pump is connected with one end of the air pipe 8 extending out of the channel 9, the solenoid valve is connected on the air pipe 8 connected between the micro air pump and the air nozzle 7, the solenoid valve is connected with the tobacco stacking posture monitoring member 6 through the PLC controller, and the tobacco stacking posture monitoring member 6 is located between the air nozzles 7.

[0041] In actual application, when the tobacco stacking posture monitoring member 6 monitors that the tobacco in the tobacco falling groove 5 close to one end of the first blowing member 2 is stacked higher, the tobacco stacking posture monitoring member 6 controls the solenoid valve to be in an open state through the PLC controller, the air generated by the micro air pump is transmitted to the air nozzle 7 through the air pipe 8, the air nozzle 7 blows air to the tobacco close to the first blowing member 2, so that part of the tobacco falls on the tobacco on the other side, and the tobacco falling into the tobacco falling groove 5 tends to be in a generally flat state.

[0042] When the tobacco stacking posture monitoring member 6 monitors that the tobacco in the tobacco falling groove 5 close to one end of the second blowing member 3 is stacked higher, the tobacco stacking posture monitoring member 6 controls the solenoid valve to be in an open state through the PLC controller, the air generated by the micro air pump is transmitted to the air nozzle 7 through the air pipe 8, the air nozzle 7 blows air to the tobacco close to the second blowing member 3, so that part of the tobacco falls on the tobacco on the other side, and the tobacco falling into the tobacco falling groove 5 tends to be in a generally flat state.
