The flow direction of the sheet tobacco fed by the sheet tobacco feeder is from the bottom belt 4 of the leaf storage cabinet, passes through the first belt conveyor 2, then passes through the second belt conveyor 3, passes through the bottom belt 8 of the feeder, and finally passes through the lifting belt 10 of the feeder to enter the next process.
The feeding control system of the tobacco sheet feeding machine is divided into a pre-filling stage and a production stage.
Prefill stage:
(1) After the start of the production line combination start command. After the front-section equipment of the sheet tobacco feeder is reversely started, the bottom belt 8 of the feeder is restarted: the second belt conveyor 3 is started firstly, then the first belt conveyor 2 is started again, and finally the bottom belt 4 of the leaf storage cabinet is started. The tobacco flakes pass through the first belt conveyor 2 from the leaf storage cabinet bottom belt 4, pass through the second belt conveyor 3, and finally fall to the inlet of the feeder bottom belt 8. When the second photoelectric switch 6 is blocked by the sheet tobacco for 2 seconds, the feeder bottom belt 8 starts to run; when the fourth photoelectric switch 9 is covered by the sheet tobacco, the sheet tobacco feeder bottom belt 8 and the front-stage equipment thereof are reversely stopped: the feeding machine bottom belt 8 stops running firstly, then the second belt conveyor 3 stops running again, then the first belt conveyor 2 stops running again, and finally the leaf storage cabinet bottom belt 4 stops running, and the pre-filling stage of the sheet tobacco feeding machine is finished.

When the material-required signal generated by the downstream equipment of the sheet tobacco feeder disappears, the sheet tobacco feeder and the preceding-stage equipment are reversely started: the feeder lifting belt 10 stops running firstly, then the feeder bottom belt 8 stops running again, then the second belt conveyor 3 stops running again, then the first belt conveyor 2 stops running again, and finally the leaf storage cabinet bottom belt 8 stops running. When the first photoelectric switch 5 and the third photoelectric switch 7 are simultaneously shielded by the sheet smoke for 2 seconds, the front-stage equipment of the feeding machine is reversely stopped: the second belt conveyor 3 stops running firstly, then the first belt conveyor 2 stops running again, and finally the bottom belt 4 of the leaf storage cabinet stops running. When the production line combination stop command starts, the sheet tobacco feeder ends the production phase.
(2) Control principle of the variable frequency motor 11 at the bottom of the leaf storage cabinet: when the production stage is entered, the variable frequency motor 11 of the leaf storage cabinet bottom belt drives the leaf storage cabinet bottom belt 4 to run at a set speed V1. Starting from the moment that the second photoelectric switch 6 is blocked by the tobacco flakes, the variable frequency motor 11 of the bottom belt of the leaf storage cabinet drives the bottom belt 4 of the leaf storage cabinet to operate at a set speed V1 within 2 minutes after the second photoelectric switch is blocked by the tobacco flakes. Starting from the moment that the second photoelectric switch 6 is blocked by the tobacco flakes, 2 minutes later, the variable frequency motor 11 of the bottom belt of the leaf storage cabinet drives the bottom belt 4 of the leaf storage cabinet to run according to the speed value V. The speed value v=v1×k of the variable frequency motor 11 at the bottom of the leaf storage cabinet. Counting the number of times (N) that the first photoelectric switch 5 and the third photoelectric switch 7 are simultaneously shielded by the tobacco in every 2 minutes by utilizing a PLC (programmable logic controller) from the moment that the second photoelectric switch 6 is shielded by the tobacco, and if the number of times (N) is less than or equal to 3 times, correcting the speed of the variable frequency motor 11 at the bottom of the leaf storage cabinet by K=1; if the number (N) is greater than 3, the correction coefficient k=1-0.02 (N-3) of the speed of the variable frequency motor 11 at the bottom of the leaf storage cabinet.
According to the utility model, the three inverted triangle photoelectric switches are arranged on the upper side of the inlet of the feeding machine, so that the start and stop of the feeding front-stage equipment of the feeding machine are controlled, the problem of the failure of the contactor caused by the fact that continuous large-diameter sheet cigarettes block the full-material photoelectric switches is solved, the frequency of the bottom belt motor of the leaf storage cabinet is controlled by the number of times that the photoelectric switches at the tail part of the feeding machine are blocked in unit time, the sheet cigarette flow rate of the feeding of the sheet cigarette feeding machine is controlled, and the start and stop times of the feeding front-stage equipment of the feeding machine are reduced.
