[0002] In the normal production process of cigarettes, tobacco is fed into the cigarette rolling machine at a certain flow rate through an air conveying device. However, in special production links such as small-batch trial production (new tobacco experiments, etc.) or equipment debugging, it is not easy to use the air conveying device in the mass production system for feeding because of the small quantity. At present, in this case, the tobacco is generally pulled to the side of the equipment (cigarette rolling machine) manually, and the protective door of the tobacco box of the cigarette rolling machine is opened to add it manually. The use of manual feeding operation is not only inefficient, but also unable to effectively break up the tobacco and achieve more balanced feeding, which is not conducive to the subsequent quality control of cigarette samples.

[0023] The auxiliary tobacco-feeding device comprises a scattering feeding device 1, wherein a hopper 21 is arranged on the upper part of the scattering feeding device 1. In the present embodiment, the main body of the hopper 21 is a rectangular structure, and its length is less than the width of the tobacco feeding device at the lower part thereof, for example, less than 50 cm. This design is conducive to evenly spreading the tobacco onto the wide surface of the tobacco feeding device after being scattering (for example, if a conveyor belt is used, it can be evenly spread along the width direction of the conveyor belt); an elastic latch 18 is arranged at the lower discharge port 17 of the hopper 21, and the elastic latch 18 can be rotatably arranged in the hopper 21 through the rotating shaft 3; in the present embodiment, the discharge port 17 of the hopper 21 is provided with an elastic latch 18, and the elastic latch 18 can be rotatably arranged in the hopper 21 through the rotating shaft 3; The material inlet 17 is a rectangular opening with a length of less than 50 cm, and the main body of the elastic tongue 18 is a rectangular plate structure. Torsion springs 4 are provided at both ends of the rotating shaft 3, and the elastic tongue 18 is subjected to upward elastic force under the action of the torsion spring 4; during processing and preparation, the torsion spring 4 can be selected with different specifications according to the capacity of the hopper 21, such as the wire diameter can be selected to be 2.0 mm or above, because the torsion springs at both ends bear the weight of the tobacco, and in order to facilitate the pulling operation by personnel, the elastic tongue 18 is also fixedly connected to a pull rope 6 on one end side of the rotating shaft, and the outer end of the pull rope 6 passes through the hopper 21. During preparation, a steel wire rope can be preferably used. A limit adjustment hole 5 is vertically arranged on the lower side wall of the hopper 21. The limit adjustment hole 5 can be a plurality of small holes or a waist-shaped hole. A limit rod 19 is adjustably arranged on the limit adjustment hole 5. The limit rod 19 can be movably arranged above the elastic tongue 18 and limit the elastic tongue 18. When the limit adjustment hole 5 adopts a waist-shaped hole structure, in order to facilitate operation, in the present embodiment, a frustum 20 is arranged in the middle of the limit rod 19, and then a thread is arranged on the limit rod 19 at the outer end of the frustum 20. When in use, the frustum 20 is arranged on the inner side of the waist-shaped hole, and then the threaded section is on the outer side. The nut is used for tightening, so that the height of the limit rod 19 can be steplessly adjusted. The limit rod 19 is stopped and limited above the elastic tongue 18 to realize the adjustment of the opening of the elastic tongue 18, thereby controlling the flow rate of tobacco discharge. If a blockage occurs during the unloading process, the pull rope 6 is intermittently pulled downward and the force of the torsion spring causes the elastic tongue 18 to swing up and down to perform a mechanical unblocking operation.
