TABLE 1 data model of Preset tobacco shred Structure
| Tobacco shred structure | Filament yarn | Medium silk | Short silk | Shredded tobacco |
| The preset structural proportion% | ＜47 | ＞33 | ＜20 | ＜1.7 |
And step S2, carrying out online detection on the incoming cut tobacco to obtain cut tobacco structure online detection data.
In an embodiment of the method for improving the structure of the cut tobacco online, the step S2 may specifically include:
and step S21, detecting the size of the incoming cut tobacco.
And step S22, obtaining the filament rate, the medium filament rate, the short filament rate and the broken filament rate of the incoming cut tobacco according to the size of the incoming cut tobacco.
Exemplarily, the unprocessed tobacco shreds are selected as a comparison sample, the distribution condition of the tobacco shred structures is detected, the ratio of the long shreds, the medium shreds, the short shreds and the broken shreds is obtained, and the comparison sample is counted to obtain a table 2.
TABLE 2 Preset structural proportions of the control
| Tobacco shred structure | Filament yarn | Medium silk | Short silk | Shredded tobacco |
| The preset structural proportion% | 57.12 | 16.12 | 16.12 | 1.63 |
According to the table 2, the filament rate in the cut tobacco reaches 57.12% in the prior art, and is higher than 47% of the preset index by about 10%.
And step S3, according to the difference between the preset tobacco shred model data and the online detection data of the tobacco shred structure, flexibly screening the incoming tobacco shreds to screen out filaments and mass filaments in the tobacco shreds, and carrying out differential truncation on the screened filaments and mass filaments to convert the filaments and mass filaments into medium filaments and short filaments.
In an embodiment of the method for improving the structure of the cut tobacco online, the step S3 may specifically include:
and step S31, comparing the tobacco shred structure online detection data with the preset tobacco shred model data to obtain data deviation.
Specifically, the filament rate, the medium filament rate, the short filament rate and the shredded tobacco rate of the incoming cut tobacco are respectively compared with the filament rate, the medium filament rate, the short filament rate and the shredded tobacco rate of the preset cut tobacco model data to obtain a difference value of the two sets of data.
And step S32, according to the data deviation, the incoming cut tobacco is subjected to flexible screening processing and differential shortening processing in sequence, so that the long filaments and the mass filaments are converted into medium filaments and short filaments.
In an embodiment of the method for improving the structure of the cut tobacco online, the step S32 may specifically include:
and S321, if the data deviation is within a preset threshold range, the requirement of preset tobacco shred model data is met, and no further processing is needed.
Step S322, if the data deviation does not fall within the preset threshold value range, selecting the filaments and the mass filaments from the incoming cut tobacco through a screening area of a processing device (the specific structure is shown in figure 4) for improving the cut tobacco structure on line, and then tearing the selected filaments and mass filaments into medium filaments and short filaments through a shortening processing area.
In an embodiment of the method for improving the structure of the cut tobacco online, step S322 may specifically include:
step S3221, the supplied cut tobacco enters the sorting area from the blanking port and sequentially passes through a first sorting roller 2, a plurality of intermediate sorting rollers 3 and a tail end sorting roller 4, wherein the diameters of the first sorting roller 2 and the tail end sorting roller 4 are the same and are larger than the diameter of the intermediate sorting roller 3, multiple rows of steel needles are uniformly distributed on the circumferences of the first sorting roller 2, the middle sorting roller 3 and the tail end sorting roller 4, the steel needles on the adjacent sorting rollers are arranged in a staggered mode, and the rotating speeds are the same.
Step S3222, under the action of the height difference between the first sorting roller 2 and the middle sorting roller 3, the first sorting roller 2 throws the incoming cut tobacco forward, meanwhile, under the action of an air field formed in the rotating process of each sorting roller 3, the mixed cut tobacco with different specifications and sizes is separated in a loose mode, under the action of continuous rotation of the sorting rollers, filaments and mass filaments larger than the gap between the steel needles on the adjacent sorting rollers float above the steel needles and move forward to enter a shortening processing area, and the cut tobacco with other specifications gradually falls down along the gap between the steel needles while moving forward.
The tobacco shreds are convenient to loose and separate the mixed tobacco shreds with different specifications and sizes under the action of the internal wind. The steel needles on adjacent sorting rollers rotate in a staggered manner to form a sieve mesh (as shown in figure 5) similar to the sieve mesh on the screen, and filaments and mass filaments with the sizes larger than the size of the sieve mesh float above the steel needles and are stirred by the steel needles to move forwards. The small sized shredded tobacco falling from the sorting section falls along the gap of the steel needles on the collecting belt 8.
At the end of the separation zone, the end separation roller 4 is higher than the intermediate separation roller 3, and this height difference can prevent the cut tobacco from entering the cutting treatment zone except for filaments and lumps of cut tobacco.
Step S3223, after the filaments and the mass filaments enter the chopping processing area, the filaments and the mass filaments sequentially pass through the first chopping roller 5 and the second chopping roller 6, wherein the diameters of the first chopping roller 5 and the second chopping roller 6 are the same, a plurality of rows of steel needles are uniformly arranged on the circumferences of the first chopping roller 5 and the second chopping roller 6, and the steel needles on the rollers of the adjacent chopping rollers are arranged in a staggered mode and have different rotating speeds.
And S3224, under the action of differential motion of steel needles on the rollers of the adjacent cutting rollers, the filaments and the mass filaments entering the cutting processing area are torn into medium filaments and short filaments, and then the medium filaments and the short filaments are output through a collecting belt 8.
The small sized and cut tobacco falling from the sorting section and the cut tobacco after the chopping process both fall on the collecting belt 8.
And step S4, mixing the cut tobacco subjected to flexible screening and differential truncation with cut tobacco subjected to filament and lump silk removal.
On the gathering belt 8, the cut tobacco subjected to the shortening treatment and the cut tobacco subjected to the screening of the filaments and the lumps of filaments are mixed again, so that the composition of the cut tobacco structure can be improved.
The cut tobacco processed by the method for improving the cut tobacco structure on line is selected as an experimental sample, the distribution condition of the cut tobacco structure after processing is detected, the proportion of long threads, medium threads, short threads and broken threads in the experimental sample is obtained, the obtained data is compared with the corresponding data in the preset cut tobacco model data, and the experimental sample is counted to obtain a table 3.
TABLE 3 Preset structural proportions of the test specimens
| Tobacco shred structure | Filament yarn | Medium silk | Short silk | Shredded tobacco |
| The preset structural proportion% | 45.62 | 29.68 | 18.05 | 1.65 |
As can be seen from Table 3, compared with the control sample, the test sample obtained by the method for improving the tobacco shred structure has the advantages that the filament rate is reduced from 57.12% to 45.62%, the filament rate is reduced by 11.5%, the medium filament rate and the short filament rate are increased, the shred breaking rate is only increased by 0.02%, and the requirements of each index in the preset tobacco shred model data are met. Therefore, the method can effectively reduce the filament rate, improve the medium filament rate, control the short filament rate, hardly increase the breakage rate and further improve the composition of the tobacco shred structure.
In an embodiment of the present invention, the method for improving the structure of the cut tobacco online may further include:
and step S5, determining whether the rotating speeds of the first sorting roller, the middle sorting roller and the tail end sorting roller need to be adjusted according to the difference of the preset tobacco shred model data and the online detection data of the mixed tobacco shred structure.
In an embodiment of the method for improving the structure of the cut tobacco online, the step S5 may specifically include:
and step S51, detecting the mixed cut tobacco on line to obtain mixed detection data.
And step S52, comparing the detection data of the mixed cut tobacco structure with the preset cut tobacco model data to judge whether the data deviation of the mixed cut tobacco structure meets the preset index.
And step S53, if the requirement is met, sending the mixed tobacco shreds to the next procedure.
And step S54, if not, adjusting the rotation speed of the first sorting roller, the middle sorting roller and the tail end sorting roller.
In an embodiment of the method for improving the structure of the cut tobacco online, the step S54 may specifically include:
and step S541, if the filament rate in the mixed tobacco shreds is higher than the filament rate in the preset tobacco shred model data, increasing the rotating speed of the first sorting roller, the middle sorting roller and the tail end sorting roller.
And S542, if the filament rate in the mixed tobacco shreds is lower than the filament rate in the preset tobacco shred model data and the increment of the tobacco shred breakage rate exceeds a preset breakage rate increment threshold (for example, 0.5%), reducing the rotating speed of the first sorting roller, the middle sorting roller and the tail end sorting roller.
The increase of the tobacco shred breakage rate exceeds a preset breakage rate increment threshold value, which shows that the breakage rate is obviously increased, and the sorting rotating speed needs to be reduced at the moment.
And step S55, adopting the adjusted rotating speed to carry out flexible screening treatment and differential truncation treatment on the mixed cut tobacco again.
And step S56, remixing the reprocessed cut tobacco and the cut tobacco after the filaments and the agglomerated cut tobacco are screened out.
Through the step S5, the cut tobacco processed by the method of the invention can reach the preset index.
