Description

A kind of quantitative evaluation method of density of tobacco rod distributing homogeneity
Technical field:
The invention belongs to cigarette product technical field of quality detection, and in particular to a kind of evaluation density of tobacco rod distributing homogeneity Characterizing method
Background technique:
During production of cigarettes, after rolling up and connecting machine aspirator formation system, the Density Distribution of tobacco bunch becomes pipe tobacco Change, the density that wherein cigarette lights end is higher than other parts.Density of tobacco rod distribution is to influence one of the important indicator of cigarette quality, The physical indexs such as weight, hardness, resistance to suction, the cigarette end tobacco-falling quantity of Cigarette are not only influenced, and then influence cigarette smoke to have The burst size of evil substance, while also will affect the aesthetic quality during cigarette consumption, and then influence consumer to cigarette product Degree of recognition.Density of tobacco rod distribution uniformity coefficient be by cigarette machine fill pipe tobacco during to pipe tobacco loading it is real-time Line traffic control is adjusted, and the uniformity coefficient that the fluctuation of loading or orderly adjustment are distributed density of tobacco rod has a major impact.Cigarette Tobacco density distributing homogeneity is poor, will cause the fluctuation of biggish cigarette weight and resistance to suction, so that affecting cigarette rolls matter The stability of amount, especially cigarette end pipe tobacco loading is excessive, and cigarette is caused to influence in aspiration procedure because resistance to suction is larger The aesthetic quality of cigarette.
Currently, domestic tobacco productive corporation has begun to focus on density of tobacco rod distribution, the distribution of research density of tobacco rod is to cigarette sky Head rate, end tobacco-falling quantity and cigarette fall the affecting laws of head condition.However how quantitative assessment density of tobacco rod distributing homogeneity Method is but rarely reported.
Chinese invention patent (CN200720024015.7) provides a kind of cigarette denseness microwave testing apparatus, device tool There are the non-destructive of non-destructive testing and the Stability and veracity of density data detection.For cigarette enterprise, how to utilize It is a meaningful thing that density data, which carries out the evaluation of density of tobacco rod distributing homogeneity, it is therefore necessary to establish density of tobacco rod Distributing homogeneity evaluation method.
Chinese invention patent (CN104165822A) uses the uniformity of VC Method quantitative assessment density of tobacco rod distribution, This method evaluates density distribution uniformity using the density data of control uniform segment among cigarette, to a certain extent Reference frame can be provided to promote cigarette quality and optimal control.However it is equal to show the dense centre in both ends based on density of tobacco rod Even distribution is true, establishes a kind of full branch Cigarette density distribution uniformity evaluation method to Cigarette design and coiling process control Fixture is significant.
Summary of the invention
It is commented in view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of quantifying for density of tobacco rod distributing homogeneity Valence method.The characteristics of being generally distributed in the dense type in both ends according to density of tobacco rod distribution, first makes density of tobacco rod distribution curve, and right Density of tobacco rod data extract, and then carry out thoroughly evaluating to density of tobacco rod distributing homogeneity according to the evaluation index of building.
The purpose of the present invention is achieved by the following technical programs.
A method of evaluation density of tobacco rod distributing homogeneity, comprising the following steps:
Step 1: the calibration of cigarette axial direction moisture, density

b, cigarette axial direction density calibration
10 cigarette are tested with microwave moisture density type analyzer MW 3220, and density data is saved；Divided equally with day Also known as measure each branch pipe tobacco weight in 10 cigarette measured by MW 3220；Each branch cigarette measured by MW 3220 The average value of pipe tobacco weight be compared to compared with the average weight weighed up, and by the measured value of balance weighing value and MW3220 For density correction coefficient.
Step 2: the test of density of tobacco rod, moisture data
Moisture and density correction are carried out to MW3220 according to step 1, measured with the microwave moisture density type analyzer after correction Cigarette moisture and density data, since pipe tobacco filling fragment position from detect, detection spacing be 1mm, detection length according to cigarette Specifications parameter is set, and (because cigarette length has different size, detection length is set according to cigarette length specification It is fixed)；
Step 3: the acquisition of cigarette standard density converts the density data that microwave moisture densimeter obtains for moisture content For 12% standard density data, wherein convert formula are as follows:
W% is actual density in formulaCorresponding actual measurement moisture,For the standard density data after conversion.
Step 4: the foundation of evaluation index
1, the cigarette standard density data that will acquire carry out matrixing processing: cigarette standard density matrix A has m × n number Composition, is denoted as, Am×n.Wherein n is cigarette quantity, and m is density of tobacco rod.Whereina ijJth branch cigarette is represented at i-th of unit Density value, vectora ﹒ jFor the density value in the different unit lengths of jth branch cigarette.Vector B and C are the column of m × 1 number composition Vector is denoted as Bm×1And Cm×1。
2, the drafting of cigarette standard density distribution curve: the cigarette standard density data obtained according to the above method, with cigarette It is close to make cigarette using the cigarette standard density data on cigarette different length position as ordinate as abscissa for branch length value Spend distribution curve.
3, the evaluation index building of cigarette standard density distributing homogeneity: order matrix
In the present invention, it is also ramuscule cigarette that the cigarette, which can be conventional cigarette,.
The present invention has the advantages that being evaluated using a kind of uniformity that new method is distributed density of tobacco rod, method Simple possible, the uniformity of energy quantitative assessment density of tobacco rod distribution, while this method is in the process of evaluation density of tobacco rod uniformity In consider the dense type Density Distribution in cigarette both ends, to Cigarette design and coiling process control be of great significance.
