After being stored in a tobacco station or a distribution station, the finished tobacco sheet is delivered as needed. Before the finished tobacco sheet tobacco box is delivered, the tobacco leaves need to be unpacked and inspected according to the standard process, and non-tobacco impurities (such as weeds, etc.) in the tobacco sheet after being packed into a box need to be detected and counted. If the non-tobacco impurities exceed the execution standard, the tobacco leaves of the current grade need to be downgraded, so as to ensure the quality of the tobacco leaves delivered.
