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
With stem setting mixture proportion under, different stem morphosis eventually enters into the stem ratio of pipe tobacco in cigarette, and there are larger
Difference affects the quality stability of cigarette.The reason is that since stem in mixing, conveying and cigarette machine the technical process such as rolls
In, the stem fine crushing of part is sized, rejects, adsorbing etc. and is 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 pipe tobacco distributing homogeneity, reduces ring cigarette incidence, improves 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 in technique therewith
On matched, thin pressure fritters stem and comes into being as a result,.And the stem of more small dimension size mix match during, exist more
Serious " loss phenomenon ", i.e., the practical stem ratio for mixing pipe tobacco in cigarette are lower than design proportion, the quality stability of cigarette
It cannot be guaranteed that.

This method measures the Filling power and filament broken rate of different mixture proportion pipe blend standard samples, and establish mixture proportion with mix cigarette
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 such as stem etc. actual cement ratio example.
Chinese patent CN104198325A discloses stem ratio measuring method in pipe tobacco based on computer vision.The party
Method acquires the image of each component in pipe tobacco to be measured using image capturing system respectively, then obtains the figure of each component in pipe tobacco to be measured
As feature and the characteristic amount of stem is calculated, establishes property data base.Calculated result is to stem component analysis according to the degree of correlation
Identification, sorts out the stem in pipe tobacco to be measured by sorting system, weighs and calculate stem component ratio.This method obtains stem group
Divide proportional precision higher, but this method modeling process needs a large amount of samples accumulation, needs again when stem morphosis changes
Again it models, method owes flexibility.Simultaneously as introducing image capturing system and sorting system, method is at high cost, and operation is multiple
It is miscellaneous, it is unsuitable for the on-line analysis measurement of production.
