Description
Technical field
The utility model is related to the control systems of the feed separation amount of tobacco manufacture field, are particularly suitable for tobacco flexibility
Wind divides the adaptive control system of the feed separation amount of device.
Background technology
One of the equipment that feed separation is realized on tobacco flexibility Feng Fenqishi cigar mills primary processing line, for smoked sheet, cigarette
The different processing technologys of the tobaccos such as silk, offal, stem, expansion thread.This equipment is used after cut tobacco dries silk equipment, can be incited somebody to action
Conglomeration object (caking, rinsing ball, clusters etc.) and most of stalk label are separated, and the degree of purity of cut tobacco or stem is improved.Due to soft
Property wind does not give selection by winnowing on the spot, to do not generate substantially make it is broken.
Wind divides device, operation principle to be after tobacco product enters sorting babinet by feeder, first in side air admission
Under the action of carry out choosing of floaing, since the density and wind area of separated object material are different, separated object material is under Lateral Wind
The distance to descend slowly and lightly is also different, therefore can rationally adjust the wind speed of side air admission, and choosing of floaing is carried out to separated object body.But float choosing
The feed separation effect that mass density is not much different can be declined.In order to ensure separating effect, using secondary separation case
The vertical air inlet of body carries out a flotation again to the material selected that floats, and using the difference of its floating velocity, will mix wherein light
Material select, heavier larger material by secondary separation babinet outlet be discharged.
In the actual production process, especially per a batch of material head on assembly line, mass flow is generally than normal punishment in advance
When it is small, and often concentrate the crock for occurring falling off in a small amount of equipment and wet mass pipe tobacco, density and material characteristic with it is normal
Pipe tobacco have larger difference, wind is not achieved and divides device to supplied materials requirement：Material loosening, no-sundries, although wind divides device first
Secondary choosing of floaing can be such that most crock and wet mass pipe tobacco detach on high speed feed belt, but heavier crock and wet mass pipe tobacco meeting
Enter secondary flotation case with higher speed, or even be directly entered drawing mechanism, and since throttle opening is fixed, it is vertical to enter the wind
Amount and wind speed are identical as flow when normal punishment in advance, prevent crock and wet mass pipe tobacco lighter after secondary flotation from being gone forward side by side by separation
Enter next process.And current tobacco flexibility air classifier charging throttle opening and belt speed cannot generally automatically adjust,
It is not convenient enough.
