[0087] Specifically, when it is necessary to increase the tobacco flow, the limiting adjustment plate 292 can be adjusted away from the conveying belt 251; when it is necessary to reduce the tobacco flow, the limiting adjustment plate 292 can be adjusted close to the conveying belt 251; at the same time, by adjusting the distance between the limiting adjustment plate 292 and the conveying belt 251, the amount and thickness of the tobacco on the conveying belt 251 are limited, thereby ensuring the uniformity and stability of the tobacco during the conveying process; and by precisely controlling the flow and distribution of the tobacco, the limiting device 29 helps to reduce the equipment failure caused by the accumulation or blockage of the tobacco.

[0088] In the embodiment, the number of the feeding assemblies 1 is two or more; each feeding assembly 1 is arranged along the length direction of the first conveying module 21; the material collecting inlet 282 of the first conveying module 21 is arranged at the top of the conveying shell 23 and along the length direction of the conveying shell 23; by arranging two or more feeding assemblies 1, the feeding operation can be carried out in parallel, thereby significantly improving the feeding efficiency; the plurality of feeding assemblies 1 can simultaneously supply the tobacco to the first conveying module 21, so that the production capacity of the entire conveying device is improved, and several feeding assemblies 1 can be selected to be enabled according to the demand.

[0089] In the embodiment, as shown in Figure 7 the height of the conveying inlet 26 of the second conveying module 22 is lower than the height of the conveying outlet 27; the height of the conveying inlet 26 of the second conveying module 22 is lower than the height of the conveying outlet 27, so that the tobacco is conveyed from low to high during the conveying process, and the tobacco is prevented from being accumulated too high by the action of gravity, thereby avoiding the situation that the accumulation of the tobacco is too high to affect the boxing.

[0090] The height of the conveying outlet 27 of the second conveying module 22 is higher than the height of the conveying shell 33, and the top of the conveying shell 33 is provided with a feeding inlet 338; the tobacco falls on the tobacco conveying part 34 through the conveying outlet 27 of the second conveying module 22 and the feeding inlet 338.

[0091] In the embodiment, as shown in Figure 8 the conveying shell 33 further comprises guide plates 335 arranged at the feeding inlet 338, and the side plates 331 on both sides of the bottom plate 332 are provided with the guide plates 335; one side of the guide plate 335 is connected with the side plate 331, and the other side of the guide plate 335 extends outward; the distance between the guide plates 335 gradually decreases from the top end to the bottom end, so that the tobacco can be prevented from falling out and causing waste as much as possible when the tobacco enters the tobacco conveying assembly from the feeding inlet 338.

[0092] In the embodiment, as shown in Figures 8 to 10As shown, the guide plates 335 or the side plates 331 are provided with a baffle 336; the baffle 336 is transversely arranged above the conveying belt 35, and the baffle 336 is away from the upper surface of the conveying belt 35; thereby, when the cut tobacco is accumulated on the conveying belt 35 through the feeding port 338, the accumulated cut tobacco can be spread by the baffle 336, so that the cut tobacco can be more evenly loaded into the box.

[0093] It is worth mentioning that other technical solutions of the present application are all prior art, so no further description is given. Although some specific embodiments of the present application have been described in detail through examples, those skilled in the art should understand that the above examples are only for illustration, not for limiting the scope of the present application. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
