Description
Technical field
The present invention relates to a kind of system and methods for tobacco structure adjustment and degree of purity optimization, belong to pipe tobacco processing skill
Art field.
Background technique
During current production of cigarettes, cut tobacco occupies very high ratio in finished product cigarette raw material, and pipe tobacco is passing through
Cross after being dried the structure for often still containing ingredients such as clusters, wet mass, burnt piece, the stalk label much wound, affecting pipe tobacco and
Finished cigarettes quality, specific manifestation are as follows:
The clusters and wet mass wound in cut tobacco, natural cooling cake easy to form influence the subsequent flavoring uniformity and mix
With uniformity, and the mildew of cut tobacco is easily caused, while the uniformity of tobacco structure can be adversely affected.
The stalk label contained in cut tobacco affect the consistency of Sensory Quality of Cigarette, the even meeting in burning of part finished product cigarette
There is phenomena such as snuff and torticollis, and also can therefore occur finished product cigarette weight mark in cigarette production process partially and run showing for item
As, while it has an effect on cigarette appearance, occurs the phenomenon that stalk label puncture cigarette paper when serious.Present part cigar mill is for stalk
The rejecting of label is mainly handled using mica wrappingmachine group, there is a problem that accidentally picking that rate is higher, pipe tobacco is lost larger, rejects efficiency
It is relatively low.
Cut tobacco adjustment reduces the long filament rate in pipe tobacco, improves middle silk rate, short silk rate in pipe tobacco, filament broken rate is as far as possible
It is constant, its advantage is that reducing the long filament rate in pipe tobacco, advantageous to the Key Quality Indicator of cigarette finished product, such as it is conducive to improve cigarette
The stability of weight, solve the problems, such as end tobacco-falling, reduce cigarette between resistance to suction variation the problem of etc.；In addition, high speed mica wrappingmachine group
It is more sensitive to the situation that long filament is excessive, a phenomenon is run since long filament is excessively easy to appear；Cigarette development becomes after especially
Gesture develops toward ramuscule cigarette, and long filament excessively will affect ramuscule tobacco quality (such as resistance to suction, mark are inclined, end end falls silk, pipe tobacco uniformity).Cause
This, reduces the long filament rate of pipe tobacco, the developing direction that short silk rate is tobacco business in increase.Currently, tobacco business is to tobacco structure
The method of adjustment mainly has fixed length chopping and big and small blade separation, and the latter is to avoid forming length by large stretch of chopping from source
Silk.Although both modes can act as reduces the long filament rate of pipe tobacco, short silk rate in increase, but all considerably increases broken silk
Rate, to cause that pipe tobacco loss is larger, is all can also have difference using direct fixed length cutting additionally, due to above two mode
The disadvantages of controllability of pipe tobacco length is not strong.
Summary of the invention
In view of the above existing problems in the prior art, the present invention provides one kind for tobacco structure adjustment and degree of purity optimization
System and method, can effectively adjust tobacco structure, reduce the material loss in volume packet production link, while can improve to obstruct and sign
Reject efficiency, and then pipe tobacco degree of purity needed for guarantee cigarette.

It is a kind of for tobacco structure adjustment and degree of purity optimization system working method, specific steps are as follows:
A, the pipe tobacco mixture after baking silk is transported in screening plant 1, pipe tobacco mixture falls on multiple groups bar screen plate 1-3
On, multiple groups bar screen plate 1-3 is vibrated with I 1-1 of jigging conveyer, and then is driven pipe tobacco mixture to roll to pneumatic separation device I 6 and moved
It is dynamic, in pipe tobacco mixture rolling moving process, the movement of finger can be simulated, clusters are ceaselessly jolted, keep clusters loose
It dissipates, and then becomes free silk；In short pipe tobacco can be fallen on from the gap on bar screen plate 1-3 on I 1-1 of jigging conveyer it is mobile after fall
Onto jigging conveyer II 2, conglomeration pipe tobacco can with bar screen plate 1-3 it is mobile after enter dispersing device I 5, I 5 pairs of dispersing device
Conglomeration pipe tobacco carry out long filament beat short and clusters it is loose after fall on jigging conveyer II 2 and enter pneumatic separation device together with short pipe tobacco in
In I 6；
B, pipe blend enters in pneumatic separation device I 6, keeps air-flow bottom-up in pneumatic separation device I 6 by the driving of blower I 3
Flowing, using long pipe tobacco and in short pipe tobacco, stalk label, clusters, sundries in the gas flow floating velocity difference progress level-one selection by winnowing, by
Suspension wind speed needed for short pipe tobacco is smaller in, and suspension wind speed needed for obstructing label, clusters is larger, therefore adjusts the wind speed of selection by winnowing
After being in the appropriate value needed for short pipe tobacco and stalk label and clusters between floating velocity, long pipe tobacco and in short pipe tobacco passed through with air-flow
The selection by winnowing air outlet of pneumatic separation device I 6 reaches main air duct 10, subsequently into feeder 11, not with stalk label, the sundries of upward gas flow
(such as burnt piece, crispy rice), the long pipe tobacco of clusters and part are fallen on III 6-2 of jigging conveyer after being conveyed from I 6-1 of selection by winnowing cabinet
Impurity outlet discharge (i.e. completion primary election process)；
C, the stalk label by level-one selection by winnowing, clusters, the long pipe tobacco in part and sundries enter in dispersing device II 7, are breaing up dress
It sets II 7 pairs of conglomeration pipe tobaccos to carry out long filaments and beat short and clusters loosely entering in pneumatic separation device II 8 afterwards, driving by blower II 9 makes gas
Flow the bottom-up flowing in pneumatic separation device II 8, using long pipe tobacco and in short pipe tobacco, stalk label, clusters and sundries hang in the gas flow
The difference of floating speed carries out second level selection by winnowing, and the wind speed of second level selection by winnowing is greater than the wind speed of level-one selection by winnowing, long pipe tobacco and in short pipe tobacco with
Air-flow reaches main air duct 10 through the selection by winnowing air outlet of pneumatic separation device II 8, subsequently into the stalk in feeder 11, not moved with air-flow
It signs and sundries falls on IV 8-2 of jigging conveyer after being conveyed and is discharged from the impurity outlet of II 8-1 of selection by winnowing cabinet, complete second level selection by winnowing
Process (i.e. refining process)；
D, in entire winnowing process, come by adjusting bar screen plate 1-3 medium rod stripe pitch and the air quantity of level-one selection by winnowing
Control enters the mass flow of dispersing device I 5 and dispersing device II 7；By adjusting in dispersing device I 5 and dispersing device II 6 two
Clusters are loose and long filament beats short degree for controlling for a roller turn speed；Wind is controlled by adjusting the air quantity of second level selection by winnowing
The degree of purity of pipe tobacco after choosing.
