monitoring a single cigarette rejection signal, monitoring rejection counts of a Y7M rejection valve and a Y8M rejection valve, outputting high level set time C from a Q0.0 end of a data processing module when the rejection counts reach 150, electrifying a relay K104M, attracting the set time C by a three-phase power normally-open contact, stopping after the waste cigarette conveying belt (1) runs for the set time C, and then controlling a counter inside the data processing module to zero;

step five: when the double cigarette extraction button is pressed, the data processing module receives a double cigarette extraction signal, then, a high level set time D is output through a Q0.0 end, the relay K104M is electrified, the three-phase power normally-open contact of the relay K104M is attracted for the set time D, the waste cigarette conveying belt (1) stops after running for the set time D, and waste cigarettes on the waste cigarette conveying belt (1) are emptied; manually attracting the metal straight rod (5) at the lower end with the bar magnet (6); monitoring double cigarette rejection signals, outputting high level setting time E through a Q0.0 end when the double cigarette rejection signals are detected, electrifying a relay K104M, attracting the three-phase power normally-open contact for setting time E, stopping the waste cigarette conveying belt (1) after running for setting time E, delaying the setting time F by a data processing module to control an electromagnetic valve Y1 to open for setting time G, enabling an air jet row A (8) to work after delaying for setting time F, blowing the waste cigarette on the waste cigarette conveying belt (1) to the right part of the conveying belt, inputting the waste material to the right part of a feed inlet of a waste material collection box (3) through a large-inclination elevator, entering a magnetic-attraction-falling type waste cigarette extraction bin, and extracting the waste cigarette from the extraction bin;

when a single cigarette extraction button is pressed, the data processing module receives an extraction single cigarette signal, then, a high level set time H is output through a Q0.0 end, a relay K104M is electrified, a three-phase power normally-open contact of the relay K104M is attracted for the set time H, the operation of the waste cigarette conveying belt (1) is stopped after the set time H, and waste cigarettes on the waste cigarette conveying belt (1) are emptied; manually attracting the metal straight rod (5) at the lower end with the bar magnet (6); monitoring a single cigarette rejection signal, outputting high level set time I through a Q0.0 end when the single cigarette rejection signal is detected, electrifying a relay K104M, attracting the three-phase power normally-open contact for set time I, stopping the waste cigarette conveying belt (1) after running for set time I, delaying the set time J by a data processing module to control an electromagnetic valve Y1 to open for set time K, enabling an air jet row A (8) to work after delaying for set time J, blowing the waste cigarette on the waste cigarette conveying belt (1) to the right part of the conveying belt, inputting the waste material to the right part of a feed inlet of a waste material collecting box (3) through a large-inclination elevator, entering a magnetic-attraction-falling type waste cigarette extraction bin, and extracting the waste cigarette from the extraction bin;

6. The method of claim 5, wherein the time A is set to 30 seconds; setting the time B to be 15 seconds; setting the time C to be 15 seconds; setting the time D to be 10 seconds; setting the time E to be 15 seconds; setting the time F to be 1 second; setting the time H to be 10 seconds; setting the time I to be 15 seconds; the set time J was 3 seconds.
