Description

Tobacco shred feeding device Technical Field The utility model relates to the technical field of tobacco processing, in particular to a tobacco shred feeding device. Background The feeding bin is one of important auxiliary devices in a tobacco manufacturing workshop of a tobacco enterprise, has the main functions of buffering materials, is matched with an electronic belt scale and a metering tube to stabilize the material flow of subsequent procedures, and is necessary front-end equipment in each process section of a tobacco manufacturing line, and the structure of the feeding bin generally comprises a storage bin mechanism and a lifting mechanism. In the actual production operation process, certain adhesion leakage conditions exist at the connection positions of the straight conveying belt of the storage bin mechanism and the lifting slope belt of the lifting mechanism and at the connection positions of the straight conveying belt and the lifting slope belt of the lifting mechanism, and a large amount of left tobacco leaves (or cut tobacco) are reserved in a receiving box at the bottom of the feeding bin. According to the quality process requirements of cigarettes, materials in the material receiving box are reduced to the current batch materials after the production of each batch of tobacco leaves is finished, so that the material loss in the cut tobacco manufacturing process is reduced, and the integrity of the batch formula of the cigarettes is ensured.
