Description
Technical field
The invention belongs to tobacco leaf wind subset fields, and in particular to a kind of method that tobacco leaf wind subset frequency is adjusted.
Background technique
The ratio of Ye Zhonghan stalk is the important performance assessment criteria of finished product sheet cigarette after beating and double roasting is raw.Rate containing stalk in finished product sheet tobacco leaf
Cigar mill's scrap prodn. line chopping effect is directly affected, the quality of tobacco product cigarette is caused, the final quality for influencing finished product cigarette.Mesh
It is preceding in beating and double roasting enterprise, the control of the rate containing stalk in leaf obtains rate containing stalk in practical leaf generally by sampling, offline inspection
As a result；Equipment control staff sets wind subset in conjunction with itself experience to the adjustment of wind subset, control according to comparison result
Determine frequency to be adjusted.Frequency is adjusted using this mode, is limited by manual operation experience, causes equipment to adjust frequently, Ye Zhong
The index fluctuation of the rate containing stalk is big, needs the long period can stabilized product quality.
Summary of the invention
It is an object of the invention to: a kind of method that tobacco leaf wind subset frequency is adjusted is provided, product quality is improved.
Technical scheme is as follows: a kind of method that tobacco leaf wind subset frequency is adjusted, the following steps are included:
S1: in the beat leaf section of threshing and redrying production line, site operation people determines that wind divides sample point according to production requirement, and
Sample point is divided to be numbered according to 1~14 serial number wind；
S2: dividing sample point to carry out the sample detection of rate containing stalk in leaf one by one 1~No. 14 wind determined, obtains in leaf containing stalk
Rate；Rate containing stalk show that current wind divides sample point compared with the tobacco leaf theory leaf rate containing stalk processed in the leaf that will test
The deviation a of Ye Zhonghan stalk rate, rate containing stalk in the theoretical leaf of rate containing stalk-in the leaf that a=is detected, judge whether needs again into
Whether the row sample detection of rate containing stalk and wind subset frequency need to adjust, judgment method are as follows:
If | ai|≤Z1, i=1~14, then detection is normal, and wind subset setpoint frequency does not need to adjust；
If Z1 < | ai|≤Z2, then divide sample point to be sampled detection again the wind, and wind subset setpoint frequency is uncomfortable
It is whole；
If | ai| > Z2 is then sampled detection again, and carries out the adjustment of wind subset setpoint frequency,
Wherein ai: current wind divides the deviation of rate containing stalk in the leaf of sample point i；
Z1: the deviation of rate containing stalk in normal leaf；
Z2: the deviation of rate containing stalk in amplification leaf；
S3: after the detection of S2 adjustment, to needing to be sampled detection, and wind subset setpoint frequency in S2 again
Unregulated sample point, i.e. Z1 < | aiThe sample point of |≤Z2 carries out wind again and divides sample detection, detection method are as follows:
If | ai|≤Z1, detection is normal, and wind divides setpoint frequency not need to adjust；
If ai、biEnd value is one positive one negative, is sampled detection again, wind subset setpoint frequency does not adjust；
If ai、biEnd value is all positive value or is negative value, and Z1 < | ai|≤Z2 is sampled detection again, carries out wind point
The adjustment of equipment setpoint frequency；
If | ai| > Z2, is sampled detection again, and wind subset setpoint frequency does not adjust；
S4: to needing to be sampled detection, and the sample point of wind subset setpoint frequency adjustment in S2 again, i.e., | ai|>
The sample point of Z2 carries out wind again and divides sample detection, detection method are as follows:
If | ai|≤Z1, detection is normal, and wind divides setpoint frequency not need to adjust；
If ai、biEnd value one positive one is negative and Z1 < | ai|≤Z2 is sampled detection again, carries out the setting of wind subset
Frequency adjustment, if ai、biEnd value is all positive value or is negative value, is sampled detection again, carries out wind subset setpoint frequency tune
It is whole；
Wherein aiFor rate containing stalk in the leaf of currently practical detection, biRate containing stalk in practical leaf was detected for last time, SetFi is to adjust
Whole frequency values, k are empirical coefficient, take 0.8~1.1.
In the S2, Z1=0.1~0.25.
In the S2, Z2=0.25~0.35.
In the S2, wind subset setpoint frequency method of adjustment are as follows: SetFi=| ai| * k, if ai< 0, then increase wind frequency dividing
Rate, if ai> 0, then reduce wind crossover rate；SetFi is that current wind divides sample point i to adjust frequency values, and k is empirical coefficient；
K takes 0.8~1.1.
In the S3, wind subset setpoint frequency method of adjustment are as follows: SetFi=(| ai|+|bi|)/2*k, if ai < 0 or bi <
0, increase frequency, if ai> 0 or bi> 0, reduce frequency；If there is ai、biTwo values are one positive one negative, and frequency does not adjust；Wherein aiFor
Rate containing stalk in the leaf of currently practical detection, biRate containing stalk in practical leaf was detected for last time, SetFi is wind subset setpoint frequency tune
Whole value, k are empirical coefficient；
In the S3, k takes 0.8~1.1.
In the S4, wind subset setpoint frequency method of adjustment are as follows: SetFi=(| ai|+|bi|)/2*k, if ai< 0 or bi <
0, increase frequency, if ai> 0 or bi> 0, reduce frequency；If there is ai、biTwo values are one positive one negative, and frequency does not adjust.
In the S4, k takes 0.8~1.1.
In the S4, k takes 0.8~1.2.
Remarkable result of the invention is: realize the automatic calculating of wind dispensing device frequency setting value, can quickly,
The accurately setpoint frequency of adjustment wind subset, reduces manual intervention, eliminates since artificial experience causes wind subset to be joined
The number adjustment frequency is more, needs the long period just and can control the problem of stable state produces and processes, and reduces the broken rate of tobacco leaf after beating, from
And improve the quality of the tobacco leaf of processing.
