[0002] In tobacco production, the tobacco in the carton needs to be sampled, and the density deviation of the tobacco in the corresponding carton is detected by the sampled tobacco sample. However, the traditional sampling of tobacco is manually sampled, which not only wastes manpower but also is low in efficiency, and the sample taken in the carton by human is not uniform enough, which affects the detection result.

[0037] After sampling is completed, the sampling tube 21 is lifted through the screw lifting assembly 24, and the packing machine 1 is also lifted after completing the pressing, so as to facilitate the transfer of the compacted tobacco box, and the lower pressing plate of the packing machine 1 does not interfere with the structure of the present scheme. The lower end of the sampling tube 21 is extended to a position just above the cutter head 36 through the screw lifting assembly 24.

[0038] As shown in Figure 2 , the sampled tobacco is in a compact state and filled in the sampling tube 21, since one end of the sampling tube 21 is fixed below the connecting plate 22, the sampling pushing cylinder 23 is fixed above the connecting plate 22, the piston rod of the sampling pushing cylinder 23 penetrates through the connecting plate 22 and extends into the sampling tube 21, and the end of the piston rod of the sampling pushing cylinder 23 is matched with the inner wall of the sampling tube 21.
