Fig. 1 is a flowchart of a method for selecting a leveling tray of a cigarette making machine according to an embodiment of the present invention.
Detailed Description
The core of the invention is to provide a method which greatly shortens the selection time of the leveling disk and solves the problem of difficult selection of the leveling disk of the cigarette making machine.
In order to make those skilled in the art better understand the technical solutions provided by the present invention, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, an embodiment of the present invention provides a method for selecting a leveling plate of a cigarette making machine, including the steps of:
step 100: defining a selection factor k for a flat disc, wherein k ═ Df 2÷(Df+Db) Wherein D isfTo level the depth of the deep groove of the disc, DbThe depth of the shallow groove of the leveling disc is set;
step 200: determining the quality requirement of cigarettes, wherein the quality requirement is understood by those skilled in the art to mean that the empty head rate of a cigarette making machine is less than or equal to 0.3%, the cut tobacco quantity of the cigarette end is less than or equal to 8 mg/cigarette, the empty loose ratio of the cigarettes is less than 5%, and the like;
step 300: for selection factor k is greater than or equal to 2.0mm, and DfAnd testing the leveling disks of not less than 3mm one by one until the leveling disk meeting the quality requirement is found.
Compared with the content introduced in the background art, the scheme only needs to test the requirement D one by onefThe test quantity of the leveling disk is greatly reduced, the selection time of the leveling disk is shortened, and the selection difficulty of the leveling disk is further reduced.
It should be noted that the above method for selecting the leveling plate of the cigarette making machine is mainly applied to the YJ19 type cigarette making machine, but the deep groove depth D of the leveling plate corresponding to the YJ19 type cigarette making machine is generally usedfThe selection factor is obtained by experimental modeling analysis, the negative correlation between the selection factor and the cigarette empty head rate is obtained, and when the most basic quality requirement of the cigarette is met, the selection factor k selected by the YJ19 type cigarette making machine generally needs to be more than or equal to 2.0 mm.
In a specific embodiment, the calibration disks with the selection factor k being greater than or equal to 2.0mm are tested one by one in step 300, specifically, the calibration disks are tested one by increasing the gradient of 0.2-0.4mm each time, starting with the selection factor k being greater than 2 mm. It should be noted that, the larger the selection factor is, the higher the requirements on the tobacco shred smoking ability of the cigarette and the quality of the tobacco shred are, so the standard disk with the smaller selection factor is generally selected as much as possible. And by the method for gradually increasing the k value from k to 2mm, the k value of the selection factor corresponding to the obtained qualified standard disk is the minimum. It is to be understood, of course, that the above-described test with a step-wise increase from k 2mm is merely the preferred way in which embodiments of the present invention may be used. In addition, the embodiment of the present invention preferably uses a gradient of 0.2-0.4mm per increment, but it is understood that other gradient values, such as 0.1mm, 0.14mm, etc., are also possible.
In a further aspect, the aboveThe flat plates with the selection factor k larger than or equal to 2.0mm are tested one by one, and particularly, when the filling capacity of the cigarettes is larger than or equal to 4.3g/cm3Then, the test was conducted with the k value gradually increased and decreased with k 2.5mm as the center value; when the filling capacity of the cigarette is 4.0-4.3 g/cm3Then, the test is carried out by gradually increasing and decreasing the k value with the k being 2.8mm as the center value; when the filling capacity of the cigarette is less than or equal to 4.0g/cm3The test was conducted while gradually increasing and decreasing the k value centering on k 3.0 mm. According to the scheme, the selection test of the leveling plate is refined according to the filling capacity of the cigarettes, and the test process of the leveling plate is further simplified.
Further, the gradient in which the central value gradually increases and decreases the k value is 0.2 to 0.4 mm. The method specifically comprises the following steps: when the filling capacity of the cigarette is more than or equal to 4.3g/cm3Then, the k value is measured by taking k as a central value of 2.5mm, and the k value is increased and decreased by 0.2-0.4mm each time; when the filling capacity of the cigarette is 4.0-4.3 g/cm3Then, the k value is measured by taking the k value as 2.8mm as a central value, and the k value is increased and decreased by 0.2-0.4mm each time; when the filling capacity of the cigarette is less than or equal to 4.0g/cm3The test was conducted with k being 3.0mm as a central value, and k was increased and decreased by 0.2 to 0.4mm each time. It will of course be appreciated that other gradient values are possible, such as 0.1mm, 0.14mm, etc.
The relationship between the flat disc factor and the empty head rate is described below with reference to a specific test procedure:
a three-factor three-level test of a leveling disc of the cigarette making machine is carried out through an L9(34) orthogonal test design, ten groups of test cigarettes are obtained together with a control blank test, the tobacco density of each cigarette of the ten groups of cigarettes and the cigarette making machine blank rate are respectively measured, and the correlation between the tobacco density of each point of the ten groups of cigarettes and the cigarette making machine blank rate is analyzed. See table one specifically:
correlation analysis of cigarette end point cut tobacco density and cigarette machine blank ratio (Table 1) (cm3/g,%)
According to the correlation between each point and the cigarette machine empty head rate, the tobacco density of each point of the cigarette end has a strong negative correlation with the cigarette machine empty head rate, the correlation is strongest at the position of 4-5mm, and is obviously weakened after 6mm, so that the correlation with the cigarette empty head rate can be established by adopting the average value of the cigarette density from the top end to the position of 5 mm.
Correlation analysis of the average tobacco density at the cigarette ends with the cigarette machine blank ratio (Table 2) (cm3/g,%)
From the second table, it can be seen that the absolute value of the correlation coefficient between the average tobacco shred density of 0-5mm and the cigarette end missing rate reaches the maximum value of-0.864, considering the significant negative correlation between the cigarette end density and the cigarette end missing rate. The aim of reducing the cigarette end missing rate can be achieved by improving the average value of the density of the end part of the cigarette with the diameter of 0-5 mm.
Through modeling analysis, the correlation between the specification of the leveling disc and the average value of the tobacco density of 0-5mm cigarettes is researched through various combination modes. The optimal correlation is shown in the following table:
k＝Df 2÷(Df+Db) (Df-disc depth of leveling; db-disc shallow groove depth. )
Since the average tobacco density of 0-5mm is related to the weight of tobacco, the regression analysis of the average tobacco density of 0-5mm, the selection factor of the leveling disk and the amount of tobacco in the cigarette can be seen, and the correlation coefficient R is 0.943, and R2 is 0.889%.
The correlation formula is as follows: 652.6018M +11.56453k-220.692 (wherein Y represents the average value of the density of the cut tobacco at the position of 0-5mm, M represents the weight of the cut tobacco, and k represents a standard disk selection factor)
The correlation coefficient a is 0.943, which shows that the established mathematical model can effectively explain the average value of the tobacco density of 0-5 mm. Theoretically, the average density of the tobacco shreds of 0-5mm can indicate the filling amount of the tobacco shreds at the end of the cigarette to indicate the compaction degree of the end of the cigarette, and can be completely used for replacing the cigarette empty rate. And under the condition that the weight M of the cut tobacco is certain, the relation only related to the selection factor of the leveling disk is changed.
The correlation formula is as follows: y11.56453 k + b (b is constant)
Therefore, when the average disk is selected, whether the cut tobacco at the end part is full can be determined by adopting the selection factor of the level disk, so that the aim of controlling the cigarette end missing rate is fulfilled.
The filling capacity of the tobacco shreds is 4.0-4.3 cm3The cigarette per gram approximately conforms to the following standard plate selection rules:
note: according to the test, the stronger the filling capacity of the cut tobacco, the lower the range of the standard disk selection factor can be selected.
The range of the selection factors of the leveling disk can be selected in a targeted manner according to the filling capacity of the cut tobacco, and the depth D of the deep groove of the leveling disk is reversely pushed according to the rangefAnd shallow groove depth DbAnd (5) specification. The leveling plate selected according to the rule can meet the basic requirement of cigarette enterprises on the compaction effect of the end part of the leveling plate, only needs a plurality of tests,the specification of the final leveling disk can be determined, the selection time of the leveling disk is shortened, and the selection difficulty of the leveling disk is further reduced.
It should be noted that the above method for selecting the leveling plate of the cigarette making machine is mainly applied to the YJ19 type cigarette making machine, but the deep groove depth D of the leveling plate corresponding to the YJ19 type cigarette making machine is generally usedfNot less than 3mm, and obtaining the relationship that the selection factor and the cigarette end missing rate (wherein the cigarette end missing rate is a main index reflecting the compaction degree of the end part) are in negative correlation by utilizing experimental modeling analysis. Although the strict application of the method is only suitable for the YJ19 type cigarette making machine, the method also has certain guiding significance for the selection of the leveling disc of other cigarette making machines.
The method for selecting the leveling disk of the cigarette making machine provided by the invention is described in detail above. It should be noted that, in the present specification, the embodiments are all described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments may be referred to each other.
