9. cigarette machine feed sett frame according to claim 1, it is characterized in that: the bottom of described air chamber (19) is provided with a point cigarette block (20), divide cigarette block (20) to stretch into from central authorities and carry a passage (21), make the tobacco stream (61) carried in a passage (21) form two tobacco bunch.
10. cigarette machine feed sett frame according to claim 9, it is characterized in that: described in carry a passage (21) bottom inlet end be provided with shunting removable wall (22), shunting removable wall (22) can rotate around fixing point; By changing shunting removable wall (22) relative to the angle of inclination carrying a passage (21) central axis, thus control the uniformity of pipe tobacco twice when formation two tobacco bunch, to improve tobacco stream carrying the shunting effect in a passage (21).
The operation method of 11. cigarette machine feed sett frames according to claim 1, is characterized in that, comprise the following steps:
The first step, the input of raw material pipe tobacco;
To be taken out from buffer storage area by raw material pipe tobacco by steep angle elevator (11) and upwards promote, raw material pipe tobacco, through the outlet at 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); Raw material pipe tobacco springs down from porcupine roller (13) by the elater rumble (14) reversely rotated with porcupine roller (13), forms raw material tobacco stream (60); The raw material pipe tobacco springed 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 arcuately curved surface slips into and laterally accelerates transfer passage (16);
Second step, raw material pipe tobacco accelerates under the effect of air-flow;
After raw material pipe tobacco enters and laterally accelerates transfer passage (16), under the effect that fan with low voltage (32) provides delivery air to raw material pipe tobacco, the accelerated motion of raw material pipe tobacco;
Raw material pipe tobacco moves near the horizontal outlet accelerating transfer passage (16), is tilted to down and is thrown into once point favored area (A);
3rd step, a sorting of raw material pipe tobacco;
Negative-pressure air fan (31) produces negative pressure in air chamber (19), secondary sorting chamber (24) and carry in a passage (21) formed another strand of air-flow, because pipe tobacco and offal have different motional inertias, the raw material pipe tobacco entering once point favored area (A) laterally accelerates the air-flow (51) of transfer passage (16) and realizes sorting under coming from the air-flow (52) of secondary sorting chamber (24) and the effect of gravity coming from; Enter under the airflow function of pipe tobacco after a sorting from bottom to top and carry a passage (21), offal is sorted out and falls into offal chamber (23);
4th step, the secondary sorting of pipe tobacco;
The offal falling into offal chamber (23) tilts upward through the effect of roll (26) and is thrown into secondary sorting chamber (24), in secondary sorting chamber (24), carry out secondary sorting, enter through once point favored area (A) under the airflow function of pipe tobacco wherein from bottom to top and carry a passage (21);
Offal falls and discharges roll (29) through offal and discharges in secondary sorting chamber (24);
The offal of discharging falls into vibra shoot (30);
5th step, the output of pipe tobacco and offal;
The pipe tobacco carried in a passage (21) forms tobacco bunch, and tobacco bunch is piled up on pipe tobacco conveyer belt, exports through pipe tobacco conveyer belt;
Under the offal that offal in vibra shoot (30) produces under fan with low voltage (32) effect guides air-flow (53) and comes from the effect of offal discharge secondary air (47) in air-flow distributor (27), discharge through sending stalk pipeline.
