The operation method of 12. cigarette machine feed sett frames according to claim 1, is characterized in that, comprises the following steps:
The first step, the input of raw material pipe tobacco;
By steep angle elevator (11), raw material pipe tobacco is taken out from buffer storage area upwards and promote, raw material pipe tobacco, through the outlet of steep angle elevator (11), falls in the groove of metering hopper (12); Porcupine roller (13) quantitatively takes out raw material pipe tobacco from metering hopper (12); With the elater rumble (14) of porcupine roller (13) reverse rotation, raw material pipe tobacco is springed down from porcupine roller (13), form raw material tobacco stream (60); The raw material pipe tobacco springing down enters a passage (15) under the effect of gravity and inertia; To the bottom of a passage (15) that fall, raw material pipe tobacco slips into horizontal acceleration transfer passage (16) along arc-shaped curved surface;
Second step, raw material pipe tobacco accelerates under the effect of air-flow;
Raw material pipe tobacco enters after horizontal acceleration transfer passage (16), and the accelerated motion of raw material pipe tobacco is provided to raw material pipe tobacco under the effect of delivery air at fan with low voltage (32);
Raw material pipe tobacco moves near the outlet of horizontal acceleration transfer passage (16), is tilted to down and is thrown into once minute favored area (A);
The 3rd step, a sorting of raw material pipe tobacco;
Negative-pressure air fan (31) produces negative pressure in air chamber (19), in secondary sorting chamber (24) with carry in a passage (21) and to form another strand of air-flow, because pipe tobacco and offal have different motional inertias, the raw material pipe tobacco that enters once minute favored area (A) come from the air-flow (51) of horizontal acceleration transfer passage (16) and come from the air-flow (52) of secondary sorting chamber (24) and the effect of gravity under realize sorting; Under the airflow function of pipe tobacco after a sorting from bottom to top, enter and carry a passage (21), offal is sorted out and falls into offal chamber (23);
The 4th step, the secondary sorting of pipe tobacco;
The offal that falls into offal chamber (23) is tilted to and is thrown into secondary sorting chamber (24) through the effect of roll (26), in secondary sorting chamber (24), carry out secondary sorting, under the airflow function of pipe tobacco wherein from bottom to top, through minute favored area (A) once, enter and carry a passage (21);
Offal falls and through offal, discharges roll (29) and discharge in secondary sorting chamber (24);
The offal of discharging falls into vibra shoot (30);
The 5th step, the output of pipe tobacco and offal;
The pipe tobacco of carrying in a passage (21) forms tobacco bunch, and tobacco bunch is piled up on pipe tobacco conveyer belt, through pipe tobacco conveyer belt, exports;
The offal guiding air-flow (53) that offal in vibra shoot (30) produces under fan with low voltage (32) effect and the offal coming from air-flow distributor (27) are discharged under the effect of secondary air (47), through sending stalk pipeline to discharge.
