Method.
Background technique
Stem mixing with application in cigarette composition has saving cost of material and Harm reduction techniques tar reduction etc. important
Meaning.As the upgrading of stem technology processed is perfect, stem mixture proportion is continuously improved, and the influence to cigarette quality is more and more convex
It is aobvious.The on-line testing of production sample the result shows that, stem morphosis is an important factor for influencing cigarette quality stability, in phase
Under same stem setting mixture proportion, different stem morphosis eventually enters into the stem ratio in cigarette, and there are larger differences
It is different, affect the quality stability of cigarette.The reason is that since stem rolls etc. in technical process in mixing, conveying and cigarette machine,
Partial stem fine crushing is sized, rejects, adsorbs and be lost.
In recent years, with the rise of " in short ramuscule " cigarette, the parameter (diameter or length of such as cigarette) of Cigarette
Changed, causes existing cigarette compatibility technology, stem processing conditions can not adapt to the requirement.As ramuscule cigarette due to
Diameter is smaller, and cut width need to be often reduced in technique to improve and run distributing homogeneity in item silk, reduces ring cigarette incidence, is improved
Cigarette resistance to suction stability.And the reduction of cut width certainly will lead to tobacco structure difference, therefore the stem of compatibility also need to be therewith
It is matched in technique, thin pressure fritters stem and comes into being as a result,.And the stem of more small dimension size mix match during, deposit
Stem ratio in more serious " loss phenomenon ", i.e., practical incorporation cigarette is lower than design proportion, the quality stability of cigarette
It cannot be guaranteed that.
Chinese patent CN106896032A discloses a kind of measurement pipe tobacco, stem, reconstituted tobacco and cuts filler uniformity
Method.Content difference of this method according to cellulose and total reducing sugar in pipe tobacco, stem, reconstituted tobacco establishes assessment material and mixes

Then the associated mathematical model of Filling power and filament broken rate of silk measures the Filling power and filament broken rate of sample to be tested, and according to mathematics
Model characterization mixes the uniformity with pipe tobacco.But in actual production, tobacco, which exists, different degrees of makes broken, Filling power and broken
Silk rate fluctuation is larger, therefore this method precision is lower, still can not exact representation material actual cement ratio example.
Chinese patent CN104198325A discloses stem ratio measuring method in pipe tobacco based on computer vision.The party
Method acquires pipe tobacco each group partial image to be measured using image capturing system respectively, then obtains the characteristics of image of pipe tobacco each component to be measured
And the characteristic amount of stem is calculated, establish property data base.Calculated result identifies stem component analysis according to the degree of correlation, by
Sorting system sorts out the stem in pipe tobacco to be measured, weighs and calculate stem component ratio, and this method obtains stem component ratio
Precision is higher.But this method modeling process needs a large amount of sample accumulation, need to build again again when stem morphosis changes
Mould, method owe flexibility.Simultaneously as introducing image capturing system and sorting system, method is at high cost, complicated for operation, uncomfortable
In the on-line analysis measurement of stem production.
