Measure from the discharging groove that shakes and fall to the instantaneous flow of tobacco of oblique feed belt; And,
According to the instantaneous flow of tobacco recording, control the running frequency of oblique feed belt.
The present invention is by being arranged to corresponding relation by the running frequency of oblique feed belt with the instantaneous flow of tobacco that falls to oblique feed belt, such as the instantaneous flow of tobacco recording is larger, tiltedly feed belt running frequency is larger, thereby tiltedly the speed of feed belt is just faster, otherwise slower.Therefore at oblique feed belt, along pipe tobacco throughput direction, width is all under identical precondition everywhere, and the height that tiltedly on feed belt, pipe tobacco is stacked will keep evenly, thereby has guaranteed stablizing of every batch of pipe tobacco weight that enters impregnating autoclave, makes it to meet setting value.
As shown in Figure 3, above-mentioned measurement comprises from the discharging instantaneous flow of tobacco that groove falls to oblique feed belt that shakes:
Measurement falls into the shake instantaneous flow of tobacco of groove of discharging: utilize HAUNI belt electronic scale, pipe tobacco is shaken before groove first by HAUNI electronic belt scale falling into discharging, can obtain thus and fall into the shake instantaneous flow of tobacco of groove of discharging.
The shake charging of groove of discharging: the pipe tobacco after having weighed via HAUNI electronic belt scale, under Gravitative Loads, falls into the discharging groove that shakes, thus the shake charging action of groove of discharging completed.
Pipe tobacco is transported to oblique feed belt by the discharging groove that shakes.This step is same as the prior art, does not repeat them here.
