[0035] As Figures 1 to 2 shown in a specific embodiment of the cut tobacco loosening device, it includes: a conveying member 3, a feeding structure 2, a blowing structure 1, a nozzle assembly, and a plurality of guiding members 5.
[0036] As Figure 1As shown, the conveying member 3 is provided with a conveying channel, one end of the conveying channel is an inlet, and the other end of the conveying channel is an outlet; specifically, the conveying member 3 is a conveying pipe. The feeding structure 2 is communicated with the conveying channel, and the feeding structure 2 is adapted to convey the cut tobacco mixed with stem pieces into the conveying channel. Specifically, the feeding structure 2 can be a funnel-shaped feeding pipe, and the feeding pipe is communicated with the conveying channel at a position close to the inlet; the cut tobacco mixed with stem pieces is the dried cut tobacco. The air supply structure 1 is connected to the inlet of the conveying channel, and the air supply structure 1 is adapted to blow the cut tobacco mixed with stem pieces in the conveying channel towards the outlet of the conveying channel, and the cut tobacco mixed with stem pieces leaves the outlet of the conveying channel; specifically, the air supply structure 1 is an air inlet pipe, and the conveying air enters from the air inlet pipe. A plurality of discharge holes 4 are provided at the outlet of the conveying channel, and the number and aperture of the plurality of discharge holes 4 can be adjusted according to the actual production situation. The nozzle assembly is arranged close to the outlet of the conveying channel, and the nozzle assembly is adapted to blow an air flow towards the outlet of the conveying channel, and mix with the blowing of the air supply structure 1 to open the agglomerated cut tobacco output from the discharge holes 4 of the conveying channel and separate the stem pieces in the cut tobacco. The air flow blown by the nozzle assembly is a high-speed air flow.
[0037] Specifically, the nozzle assembly includes: an air flow conveying pipe 6 and a plurality of air flow nozzles 7. The air flow conveying pipe 6 is adapted to output an air flow; the plurality of air flow nozzles 7 are connected to the air flow conveying pipe 6, and the plurality of air flow nozzles 7 are adapted to blow an air flow towards the outlet of the conveying channel from different directions. The positions, angles and numbers of the plurality of air flow nozzles 7 can be adjusted according to actual requirements.

The agglomerated cut tobacco in the cut tobacco mixed with stem pieces reduces entanglement under the action of the two forces, separating the stem pieces wrapped therein. The fully dispersed cut tobacco enters the air separation device for the next step of stem piece removal.
