Background technology
Traditional width of peduncle thread detection method in kind is: at the about 10g of silk cutting machine outlet grab sample, the picked at random stem is 10 then, surveys its thickness as for thickness gauge respectively, calculates 10 stem average thickness value, both has been the width of this stem.There are many deficiencies in this method, causes data testing accuracy low, poor accuracy.Be embodied in following several respects:
1, this method of testing is owing to cut back moisture of cut stem big (30%-36%), and stem is very soft, under the thickness gauge elevated pressures, produces bigger retraction, makes its detected value will be far smaller than actual value.
2, it is big to cut back stem difference in size, and under identical pressure, the pressure difference that is subjected to makes the contraction difference of stem when test.(for example: the stem of same thickness, area is little, the thickness of measuring is also corresponding little).
3, be subjected to the influence of factors such as different year, the hardness of stem itself is also different, causes the more little stem of hardness, shrinks greatly more during test, and test value is more little.
4, in test process, when the testing staff chose sample, all can there be certain difference in the size of each sample, time etc.Produce certain influence to detecting data.
Can there be certain deviation inevitably in the width of cutting the back stem, and therefore, the width of peduncle thread test data must be representative, eliminates experimental error as much as possible.
Summary of the invention
The present invention provides a kind of simple to operate for overcoming above-mentioned the deficiencies in the prior art, can eliminate the error that traditional detection method produces effectively, improves accuracy and stable checking method for width of peduncle thread that width of peduncle thread detects.
The objective of the invention is to adopt following technical proposals to realize: a kind of checking method for width of peduncle thread, adopt following steps:
A. set silk cutting machine width of peduncle thread value;
B. will put into the different parts of silk cutting machine charging offal with the bigger ebonite rod of stem color distortion, and carry out chopping, the stem that will have film picks out from the silk cutting machine outlet;
C. manually sort out film, mix, appoint at random and get 10-100 complete film, measure its thickness one by one, calculate this average thickness value, be the width of this batch stem with milscale.
Described glue rod is little, the easy cutting of elasticity, and after the cutting not breakable plurality of specifications and multiple color hot melt adhesive material or have other material of similarity to make with it.
The present invention is little owing to the film elasticity that cuts out, hardness is consistent, size is identical, be not subjected to moisture effects, thereby can reflect the actual conditions of width of peduncle thread truly, objectively, has eliminated the verify error that classic method produces.
The present invention adopts glue rod detection method to detect width of peduncle thread, can eliminate the error that influence caused that detection method in kind is subjected to factors such as moisture of cut stem, stalk sheet size, offal year and testing staff's sampling custom preferably.Its test data can be represented the actual conditions of width of peduncle thread preferably, and test data is more representative than real object method.
The present invention adopts glue rod detection method to detect width of peduncle thread, and the stability of its test data is better than detection method in kind far away, and detection efficiency obviously strengthens, and has improved accuracy and stability that width of peduncle thread detects.Avoided the each test result of real object method to exist, allowed operating personnel frequently adjust the drawback of tobacco cut width, and glue rod detection method is because each width of peduncle thread test errors is less relatively, thereby actual production is had more directive significance than large deviation.
The present invention is applied to the process certification behind the checking of the daily method of testing of width of peduncle thread and calibration and the equipment medium-capital overhauling, and effect is very desirable.
The present invention also can be applicable to the detection of leaf silk width, the posterior lobe silk is cut in solution presented serrate (being commonly called as " garland " phenomenon), causes the inaccurate problem of leaf silk width detection, and is respond well.

3 results and analysis
3.1 the contrast of two kinds of test result mean value and standard deviation
Setting width with silk cutting machine is that 0.17mm is an example, analytical table 1 and table 2 data, though all within the scope of 0.17mm ± 0.03mm, it is bigger that the width of peduncle thread that adopts real object method to test departs from actual value for the width of peduncle thread mean value of employing real object method and glue rod method test as can be seen; Its mark partially also is higher than glue rod method far away, and the dispersion degree of test data is higher.Detection method in kind is described owing to be subjected to the influence of factors such as moisture of cut stem, stalk sheet size, offal year and testing staff's sampling custom, cause departing from greatly, can not represent the actual conditions of width of peduncle thread preferably as the width of peduncle thread mean value and the actual value of criterion.And glue rod method can be eliminated real object method generation reasons of error preferably, and its test data is also more representative.

3.2 two kinds of test result data stability contrast
Can see from Fig. 1 and Fig. 2, adopt glue rod method to present better normal distribution state, and along with the more close mean value of test data, the frequency of appearance be higher than the width of peduncle thread value of real object method test.Illustrate that glue rod method is higher than real object method far away to the test data stability of width of peduncle thread.If carry out real object method and glue rod method contrast test repeatedly, can find that also the each test result of real object method also all exists than large deviation in various degree, allow operating personnel when the adjustment tobacco cut width, feel not have institute's thing from.And glue rod method is less relatively owing to each test errors, thereby actual production is had more directive significance.
3.3 two kinds of test result data standardized normal distribution probability contrasts
3.3.1 real object method
Press width of peduncle thread mean value 0.15mm, franchise ± 0.03mm is a span, calculate width of peduncle thread greater than 0.12mm less than the probability of 0.18mm.
P(0.12≤X≤0.18)=P(-0.73≤μ≤0.73)=F(0.73)-F(-0.73)=0.7673-0.2358=0.5315
That is: the probability that adopts real object method test width of peduncle thread to occupy between the 0.12mm-0.18mm is about 53%.
3.3.2 glue rod method
Press width of peduncle thread mean value 0.18mm, franchise ± 0.03mm is a span, calculate width of peduncle thread greater than 0.15mm less than the probability of 0.21mm.
P(0.15≤X≤0.21)=P(-1.76≤μ≤1.76)=F(1.76)-F(-1.76)=0.96080-0.03920=0.9216
That is: the probability that adopts real object method test width of peduncle thread to occupy between the 0.12mm-0.18mm is about 92%.
3.3.3 analyze: as can be seen from the aforementioned calculation result, adopt real object method test width of peduncle thread, even its mean value is also only had only 52% as the qualified probability of its every stem of standard value, and after adopting glue rod method, its qualification rate is higher than the object test method far away but up to 92%.The stability of gelatin rod method test data and detection efficiency are significantly better than the object test method on the other hand.

Embodiment 10: when using glue rod indirect detection as different from Example 1, appoint at random and get 100 complete films, measure one by one, calculate its mean value again.
During glue rod indirect detection, along with the increase of the quantity of the film that is extracted, the accuracy of data is high more, still, chooses about 50 and chooses 100 and differ and be not too big, can satisfy the requirement of data accuracy fully.So it is 50 that best complete film is chosen numeral.
