Example

[0042] See also Figure 4 As shown, the automatic tobacco swing blending system provided by this embodiment (described in terms of the tobacco frame conveying direction) is: according to the simulated formula leaf threshing and redrying process, eight kinds of tobacco leaf types and levels are selected from 44 types and levels for formula leaf threshing and redrying, and the cache cabinets corresponding to the eight leaf threshing and redrying formulas are A-3, A-8, B-3, B-8, C-3, C-8, D-3, and D-8 in the four lines A, B, C, and D of the electronic belt cabinet 9, respectively. The following description directly uses the codes of the above eight electronic belt cabinets to replace the types and levels of the required formula tobacco leaves, as follows:

[0043] A-3 tobacco frame 2 is output from temporary storage high-bay warehouse 1, and is transported to box turner 5 at position A by the shortest path through chain conveyor 3 and rotating chain conveyor 4.
