By arranging the hopper 10 on the feeding assembly and moving the feeding assembly to the position of the tobacco, manual handling of the tobacco is avoided, labor costs are saved, and the efficiency of recycled tobacco reprocessing is improved.

[0038] In this embodiment, the air blowing assembly includes a high-speed fan and an air compressor, etc. It should be noted that since the tobacco opening equipment and the air blowing assembly are very mature technologies in the prior art, they are not described here. Specifically, the connecting pipe 20 can be set to multiple sections, or a hard pipe and a soft pipe can be spliced.

[0039] Furthermore, in order to increase the efficiency of tobacco entering the cigarette making machine, two through holes and two connecting tubes 20 are provided opposite to each other. In other embodiments, more than two through holes and two connecting tubes 20 can be provided according to the size of the hopper 10 to improve the efficiency of tobacco supply.

[0040] Further, the cross section of the hopper 10 is set to be square, and two through holes are set on the two first side walls 11 of the hopper 10. In other embodiments, the cross section of the hopper 10 can be set to be circular or triangular.

[0041] Furthermore, the feeding device also includes a guide member 30, which is arranged on the central axis of the second side wall 12 of the hopper 10 in the horizontal direction and has two arc-shaped guide surfaces, and the two arc-shaped guide surfaces extend from the central axis of the hopper 10 to the direction close to the two through holes, so as to guide the tobacco to the through holes. In this embodiment, the guide member 30 is configured as two guide plates 31, one end of the two guide plates 31 is connected to each other and the connecting end is located on the central axis of the hopper 10 in the horizontal direction, and the other end extends to the direction close to the two through holes, and the two guide plates 31 are recessed toward the central axis. In other embodiments, the guide member 30 can be configured as a block. Specifically, the width of the guide plate 31 is the same as the gap between the two second side walls 12. Prevent the tobacco from falling directly into the bottom of the hopper 10 and accumulating.

[0042] Furthermore, the guide member 30 further includes a fixing plate 32 , the two guide plates 31 are welded or screwed to the fixing plate 32 , and the fixing plate 32 is fixed to the second side wall 12 .

[0043] Further, the second side wall 12 is rotatably provided with an operation window 40.
