It can be understood that the position of the second transmission wheel 42 is changed by sliding the movable assembly 112 relative to the fixed frame 111 in the preset direction, thereby realizing the change of the position of the second transmission wheel 42 in the preset direction.

[0059] It should be noted that the position change of the second transmission wheel 42 is fine adjustment, and in general, the tension adjustment range of the upper conveying belt 43 can withstand the adjustment amount. In addition, the frame body 10 is also pivoted with a swing tobacco pressing wheel 44, and the free end of the swing tobacco pressing wheel 44 can abut against the inner side of the upper conveying belt 43 to adjust the tension of the upper conveying belt 43. Thus, when the upper conveying belt 43 is too loose, the tightening degree of the upper conveying belt 43 can be ensured by the abutting force of the swing tobacco pressing wheel 44 abutting to the upper conveying belt 43. The pressing principle of the swing tobacco pressing wheel 44 belongs to the prior art, and will not be described here.

[0060] In order to realize the position adjustment of the movable assembly 112 in the preset direction, as shown in Figure 2 and Figure 3 , the fixed frame 111 includes a body 1111 and a sliding rail 1112 connected with each other, the sliding rail 1112 extends along the preset direction and protrudes the body 1111 towards the upstream, and the first transmission wheel 41 is pivoted to the body 1111; the movable assembly 112 includes a sliding block 1121, a first lead screw 1122 and a locking screw 1123, the sliding block 1121 is in sliding cooperation with the sliding rail 1112, and the second transmission wheel 42 is pivoted to the sliding block 1121; one end of the first lead screw 1122 is pivoted to the fixed frame 111 and extends along the preset direction, and the sliding block 1121 is in threaded connection with the first lead screw 1122; the locking screw 1123 is in threaded connection with the sliding block 1121 and can abut against the sliding rail 1112. Through the above setting, when the locking screw 1123 is loosened, the first lead screw 1122 is rotated, and the sliding block 1121 can adjust the position in the preset direction, thereby driving the second transmission wheel 42 to adjust the position, and when the locking screw 1123 is tightened, the free end of the locking screw 1123 abuts against the sliding rail 1112, so that the sliding block 1121 cannot continue to slide, thereby fixing the position of the sliding block 1121.
