[0032] As Figures 1 to 6 shown, this embodiment provides a tobacco shred loosening device, which includes a support frame 1, a driving rake nail assembly 2, a driven rake nail assembly 3, and a fixed rake nail assembly 4. Among them, the driving rake nail assembly 2 has a plurality of driving rake nail bodies 21, the driven rake nail assembly 3 has a plurality of driven rake nail bodies 31, and the fixed rake nail assembly 4 has a plurality of fixed rake nail bodies 41. By using the tobacco shred loosening device provided by the present utility model, since the driving rake nail assembly 2 is rotatably arranged on the support frame 1 and the driving rake nail assembly 2 and the driven rake nail assembly 3 are in transmission connection, the driving rake nail assembly 2 can drive the driven rake nail assembly 3 to rotate. At the same time, a plurality of driven rake nail bodies 31 and a plurality of driving rake nail bodies 21 are arranged in an alternating manner, and a plurality of fixed rake nail bodies 41 and a plurality of driving rake nail bodies 21 are arranged in an alternating manner. With such a setting, during the operation of the device, the agglomerated tobacco shreds entering the tobacco shred loosening device can be completely loosened under the combined action of the driving rake nail bodies 21, the driven rake nail bodies 31, and the fixed rake nail bodies 41, and the loosening effect is improved; and the fixed rake nail assembly 4 and the driven rake nail assembly 3 are respectively arranged on both sides of the driving rake nail assembly 2, so that both sides of the driving rake nail assembly 2 can loosen the agglomerated tobacco shreds, thereby improving the loosening effect and loosening efficiency of the tobacco shred loosening device, and effectively solving the problem of poor loosening effect caused by only loosening the tobacco shreds through the driving conveying roller and the driven conveying roller in the prior art.
