The negative pressure control valve is arranged on the air suction wire feeding pipe and used for controlling the conduction or the closing of a negative pressure cavity of the air suction wire feeding pipe. The electromagnetic valve is used for controlling the opening or closing of the turning plate at the bottom of the discharger. And when the first input end of the controller receives a high level, the negative pressure control valve is controlled to be in a conducting state, so that the air suction and tobacco feeding pipe forms negative pressure to suck tobacco shreds.

And the controller reports shutdown information when the tobacco material level in the metering pipe reaches the lowest material level.
In practical application, as shown in fig. 2, when the PASSIM cigarette making machine is normally produced, the cut tobacco is taken out from the metering pipe by the metering roller 6 and enters a subsequent production flow. The photoelectric switch 4 and the photoelectric switch 5 monitor the tobacco shred material level in the metering tube, and when the cigarette making machine is in the automatic material feeding state of the discharger, if the photoelectric switch 5 does not monitor the tobacco shreds, the cigarette making machine is stopped; if the first photoelectric switch 4 does not detect the cut tobacco and a cut tobacco height detector (not shown in the figure) of the discharger detects that the cut tobacco is full, the discharger turning plate 3 is controlled to be opened. When the discharger needs to be charged, the electromagnetic valve 14Y2 is powered off, and the discharger flap 3 is closed. When the tobacco shred height detector monitors that the tobacco shreds of the discharger are empty, the controller controls the negative pressure control valve 2 to open negative pressure air suction, and the tobacco shreds enter the discharger through the tobacco shred feeding pipe; if the tobacco shred height detector monitors that the discharger is full of tobacco shreds, the negative pressure control valve 2 is closed, and the material requiring process is finished.

When the turning plate at the bottom of the stripper plate is opened, the normally open relay K is attracted, and the time-delay disconnection contact is closed again. It should be noted that the tobacco shred height detector can adopt an ultrasonic height sensor, a photoelectric sensor and an infrared sensor. The system realizes the feeding mode of 'material level + timing' of the tobacco shred hopper of the PASSIM cigarette making machine by adding a delay off relay.
