AI Technical Summary
In the existing technology, when the secondary air classifier and the secondary feeding conveyor are controlled separately, misoperation is prone to occur, resulting in some tobacco-containing materials being mistakenly fed to the stem discharge collection point.
A locking mechanism is formed by using relay J1, with its coil electrically connected to the power supply circuit of the secondary air classifier and its normally open contact electrically connected to the power supply circuit of the secondary feeder, so as to realize the synchronous control of the secondary air classifier and the secondary feeder and prevent misfeeding.
This effectively prevents the secondary feeder from continuing to run after the secondary air separator stops, avoids the tobacco material being mistakenly fed to the stem discharge point, and improves the automation control accuracy and reliability of the air separator system.
