Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco production and transportation technology, and in particular to a tobacco leaf loosening device. Background Technology
[0002] During the production and transportation of tobacco leaves, different grades of tobacco leaves are prone to clumping. Therefore, it is necessary to introduce a tobacco leaf loosening mechanism to break up and loosen the clumped tobacco leaves.
[0003] Existing tobacco leaf loosening mechanisms typically employ parallel, spaced rollers with rakes for loosening. Clumps of tobacco leaves are placed on the rollers, which rotate, causing the rakes to break up the leaf clumps. The loosened leaves fall through the gap between two adjacent rollers into a storage bin or conveyor. However, in the existing structure, the gap between two adjacent rollers (loosening distance) is fixed. During the loosening process, it is impossible to flexibly adjust the gap based on whether there are too many or too few clumps of different grades of tobacco leaves, which can easily lead to poor loosening and breaking up effects, thus affecting the overall production efficiency and tobacco processing quality to some extent.
[0004] Therefore, there is an urgent need for a tobacco leaf loosening device to solve the above problems. Utility Model Content
