Technical Field
The invention relates to the technical field of cigarette making machines, in particular to a method and a device for adjusting the axial arrangement of cut tobacco of a cigarette making machine.
Background
The industry puts higher requirements on the cigarette combustibility, and the cigarette needs to be well smoked and beautiful. By "good smoking" is meant the intrinsic quality of the cigarette, and "good looking" is meant the extrinsic quality of the cigarette after combustion. The external qualities of the cigarette after combustion include: the appearance quality of the burning ring, the height of the burning cone, the black ring, the black spot, the head distortion, the flower explosion and the like.
Factors influencing the external quality of the cigarette after combustion are many, including the combustion rate of the cut tobacco, the combustion matching of the roll paper and the cut tobacco, the structure of the cut tobacco, the purity of the cut tobacco, the filling value of the cut tobacco, the moisture content of the cut tobacco, the density of the cigarette, the axial arrangement of the cut tobacco and the like.
Among the above influencing factors, the research on the burning rate of the cut tobacco, the burning matching of the roll paper and the cut tobacco, the structure of the cut tobacco, the purity of the cut tobacco, the filling value of the cut tobacco, the moisture content of the cut tobacco, the density of the cigarette and the burning rate of the cigarette paper in the industry is relatively deep, and obvious effect is achieved. But the axial alignment of tobacco shreds has not been much studied.
The axial arrangement of the cut tobacco means that the filiform cut tobacco is arranged along the axial direction of the cigarette. Because the tobacco shred is influenced by the factors such as tobacco shred structure, curling degree, filling capacity, moisture, flow, VE negative pressure, VE positive pressure and the like in the forming process, the tobacco shred is in the cigarette: axial, transverse and oblique arrangements exist.

However, how to increase the ratio of the axial arrangement of the cut tobacco is not described in the literature.
Therefore, how to increase the ratio of the axial arrangement of the cut tobacco is a technical problem to be solved by the technical personnel in the field.

The cut tobacco in the cigarette is formed by a cut tobacco supply system and a forming system of the cigarette making machine. Theoretically, the less the tobacco shred provided by the shred supply system is, the less the influence of the similar tobacco shred on a single tobacco shred at the shred suction belt is, and the greater the probability of arrangement of the tobacco shred along the shred suction belt direction is at the moment when the tobacco shred contacts the shred suction belt under the actions of rapid operation of the shred suction belt and positive and negative pressure VE. However, the physical index, the cut tobacco amount at the end and the appearance of the cigarette are negatively affected by too little cut tobacco, so the cut tobacco amount provided by the cut tobacco supply system (note that the cut tobacco amount provided by the cut tobacco supply system is the cut tobacco usage amount of the cigarette plus the cut tobacco return amount) needs to be optimized on the premise of ensuring the physical index and the appearance of the cigarette.
The application designs an adjusting method for the axial arrangement of cut tobacco of a cigarette making machine, which is used for controlling the cigarette making machine shown in figure 1, and realizes the improvement of the proportion of the axial arrangement of the cut tobacco through the adjustment of parameter ranges in a specific sequence.
For easy understanding, please refer to fig. 2, fig. 2 is a flowchart of a method for adjusting the axial arrangement of tobacco shreds of a cigarette making machine according to an embodiment of the present application, and as shown in fig. 2, the method specifically includes:
101. adjusting the back yarn amount of the needle roller so that the back yarn amount is between 34% and 36%;
it should be noted that the cigarette making machine generally produces cigarettes with a circumference of 24.2 mm; the set value of the yarn returning amount of the needle roller is set in a weight control system.
102. The VE negative pressure of the VE negative
the negative pressure required by the tobacco shreds of different brands is different due to the differences of the tobacco shred structures, filling values and moisture, the cigarette with the circumference of 24.2mm has a filling value of 4.5cm 3/g-4.7 cm3/g detected by a 3.0kg weight, and the VE negative pressure is about-110 to-115 multiplied by 100 pa.
103. Stopping the machine, and adjusting the height of the baffle 5 of the primary stemmed swab to the highest position;
when the height of the stem removing baffle 5 is adjusted once, the
104. Opening all the small fan air doors 2;
105. starting the air conditioner, and adjusting the VE positive pressure of the small fan air door 2 within the range of 5mbar to 6 mbar;
namely, the VE positive pressure is reduced, so that the tobacco shreds at the positive pressure air chamber 3 can smoothly enter the tobacco throwing roller 11, and the tobacco shreds without up-down disturbance at the positive pressure air chamber 3 are ensured, wherein the adjusted positive pressure is generally in the range of 5-6 mbar.
106. The height of the stalk removing baffle 5 is adjusted downwards once;
the height of the stalk removing baffle 5 is adjusted downwards once to ensure that the stalks smoothly pass through the baffle and enter the screw conveyor 6.
107. And adjusting the size of the secondary stalk removing air door 7 to ensure that the material speed of the secondary stalk removing blanking port is in the range of 80g/min to 86 g/min.
Namely, the size of the secondary stalk removing air door 7 is adjusted, so that the secondary stalk removing stick can effectively separate stalks and shreds.
This application is through adjusting the size that will return silk volume, VE negative pressure, VE malleation, secondary remove stalk bamboo slips air door 7 to suitable scope according to certain order, can improve the proportion of pipe tobacco axial arrangement.
Further, the adjusting the yarn returning amount of the needle roller so that the yarn returning amount is between 34% and 36% specifically comprises the following steps:
adjusting the yarn returning amount of the needle roller, detecting whether the yarn returning amount is between 34% and 36%, if so, stopping adjusting and entering the next step, and if not, returning to continue adjusting.
Filling value of 4.5cm by leaf shred3/g～4.7cm3Testing of the amount of return of pure leaf shred brand "a smoke" in the range of/g: the cut tobacco returning amount of the cigarette making machine is gradually reduced from 42% to 40%, 38%, 36%, 34%, 32%, 30% and 28%. In the actual measurement process, the detection result of the yarn return amount cannot obtain an integral value, and the actual measurement result of the yarn return amount corresponding to the yarn return amount of the needle roller is as follows:
through the detection and analysis of the appearance and physical indexes of the cigarettes rolled by different cut tobacco returns, the dust content is increased and the empty cigarettes are increased when the cut tobacco returns are too large; and when the cut tobacco return amount is too small, the cigarette weight stability is poor, and comprehensive analysis shows that the cut tobacco return amount is in a range of 34-36%, and the comprehensive performance of the cigarette quality of A cigarettes is optimal. (Note that the set value of the yarn returning amount of the needle roller is set in the weight control system, the yarn returning amounts corresponding to the yarn returning amounts of the needle rollers of different machines are different, and the yarn returning amounts of the same machine, the same needle roller and different brands also have differences under the influence of factors such as the structure, the moisture, the filling value and the like of the cut tobacco)
Further, the VE negative pressure of the VE negative
and adjusting the VE negative pressure of the VE negative
It should be noted that the magnitude of the negative pressure can be adjusted by the damper of the dust removal duct in fig. 1.
VE negative pressure is adjusted up from-85 × 100pa to-95 × 100pa, -105 × 100pa, -115 × 100pa, -125 × 100pa, -135 × 100pa and-145 × 100pa one by one, and VE positive pressure is kept constant at 10 mbar. The result shows that the VE negative pressure of the cigarette A is in the range of-110 to-115 multiplied by 100pa, the physical index, the end cut tobacco quantity and the appearance of the cigarette are more stable relative to other parameters, but the detection result of the density stability of the cigarette is not obvious in change, the density standard deviation of 4-7 points of the cigarette ignition end is basically more than 20mg, and the maximum value is 35.2 mg. The cigarette paper is stripped from the cigarette hasp, the tobacco shreds are loosened immediately, and the arrangement of the tobacco shreds is observed to be messy. In the experimental process, the situation that a plurality of tobacco shreds in the positive pressure air chamber 3 of the cigarette making machine are disturbed up and down is discovered through careful observation, and the preliminary analysis shows that the positive pressure air is too large in the process of conveying the tobacco shreds from the positive pressure air chamber 3 to the shred throwing roller 11, the wind power is blocked, and the tobacco shreds are blown back by back blowing. Therefore, the range of the VE positive pressure needs to be adjusted by combining the test results of the early stage on the wire returning quantity and the VE negative pressure.
Further, the adjusting of the positive VE pressure of the small fan damper 2 specifically includes within the range of 5mbar to 6 mbar:
and adjusting the VE positive pressure of the small fan air door 2, detecting whether the VE positive pressure is in the range of 5mbar to 6mbar, if so, stopping adjusting and entering the next step, and if not, returning to continue adjusting.
It should be noted that the positive VE pressure of the small fan damper 2 can be adjusted by the small fan damper 2 shown in fig. 2.
Because the VE positive pressure is closely related to the primary stem removal amount, the adjustment range is considered from the range of 8-12mbar described in PROTOS-70 specification, and the change trend of the detected cigarette density is not obvious compared with cigarettes rolled out by VE positive pressure of 10mba, 9rmbar and 8mbar, and the up-and-down disturbance change of the tobacco shreds at the positive pressure air chamber 3 is not obvious. Through the examination of peeling cigarette paper of 50 cigarettes, most cigarette bundles are loose, 48 loose cigarettes account for 96% of the total detection number; which indicates that the tobacco shreds are disorderly arranged.
When VE malleation is adjusted to 7mbar, the tobacco shred volume of positive pressure plenum 3 department upper and lower disturbance begins to reduce, cigarette machine secondary removes the stem and signs the department material and begins to increase, the putty condition appears in accident, and the stem removal of this moment is signed baffle 5 and is located the lowest position. The point and value of the density standard deviation of the cigarette lighting end is reduced at the same time when the detection finds that the density standard deviation is more than 20 mg. And repeating sample detection, wherein the result is still consistent. The statistical result is as follows: the density standard deviation of each point exceeds 1-4 points and the maximum value is 29.2 mg. The cigarette paper is peeled off, the arrangement of the tobacco shreds is still messy, the cigarette paper is peeled off instantly, part of the tobacco shreds are loosened immediately and arranged in segments, and the surface of the scattered tobacco tow presents a wavy shape. Peeling and checking 50 cigarettes, wherein the whole cigarette is 31 cigarettes which are fluffy and account for 62% of the total detection number; the change of the cigarette bundle state is shown, and the change of the axial arrangement proportion of the cut tobacco is also indirectly shown.
When adjusting VE malleation to 6mbar, the cigarette machine secondary removes stalk and signs the department material increase obvious, when shutting down at every turn, removes stalk and signs the department and all can appear the putty at the secondary, and the disturbance volume phenomenon disappears about 3 departments pipe tobacco of malleation plenum, and a destemming baffle 5 is located the lowest position. The cigarette paper is peeled off by 50 cigarettes, the cut tobacco is basically bunched, most of the cigarette bundles are compact and not loose, the loose point of part of the cigarettes is obviously reduced, and the loose point is 8 points and accounts for 16 percent of the total detection number;
the test was continued with a positive VE pressure of 6 mbar. In order to solve the problems of material increase and material blockage during shutdown at the secondary stalk removing position, the baffle 5 for removing the stalks at the primary step is considered to be positioned at the lowest position, and an adjusting space is reserved. Then the height of the baffle is firstly adjusted to the highest position, and the heights of the two ends of the baffle are ensured to be at the same level. Then starting the machine, finding that the material for removing the stem sticks for the second time is greatly reduced, and the proportion of the stems and the shreds is also reduced. Then the height of the baffle is gradually adjusted downwards, and the material dropping port of the secondary stem removing stick is gradually increased from 40g/min to 120g/min without the condition of shutdown and material blockage. Through detection, when the discharge port of the secondary stem removing stick is 80-86 g/min, the content of tobacco shred stems in the cigarette is 2.8-3.4%, and the content of the stems is obviously reduced greatly compared with that of a normal product (note that the content of the tobacco stems A is about 5.7%), which indicates that the content of the stems in the cigarette is not negatively influenced by adjusting VE positive pressure and increasing the baffle 5 of the primary stem removing stick, and on the contrary, the content of the stems is obviously improved.
The sampling and the stripping of the cigarette are performed to check the conditions of the cigarette bundles as follows:
the tobacco shred arrangement is obviously changed from the tobacco shred bundles in the cigarettes (note that no instrument is used for quantification at present), the inspection result shows that the VE positive pressure is closely related to the tobacco shred bundle shape proportion, and the VE positive pressure is reduced through the stem content, the point inspection of average fluffiness of the tobacco shred bundles and the analysis of the cigarette density measurement result, so that the stem content, the tobacco shred axial arrangement proportion increase and the cigarette density uniformity in the cigarettes are obviously improved.
Continuing to reduce VE positive pressure by 5mbar, the test sample trends to be consistent with 6 mbar: the tobacco shreds in the cigarettes are basically bunched, most of cigarette tobacco shreds are compact and not loose, only part of cigarettes are fluffy, 6 puffy points are actually measured and account for 12 percent of the total detection number, the content of tobacco shred stems in the cigarettes is between 2.4 and 2.8 percent, and the average value of standard deviation of each point of the cigarette density is more than 20mg and the number of standard exceeding points is 1.0 point.
When the VE positive pressure is reduced to 4mbar, the situation that the material is blocked at the position of the secondary stem removing position can also occur when the stem removing baffle 5 is at the highest position for the first time, which indicates that the VE positive pressure has negative effects on production when the VE positive pressure is 4mbar or below.
A conclusion is reached by the above tests and results: the positive pressure of the cigarette making machine is a key factor influencing the axial arrangement of the cut tobacco. To improve the proportion of the axial arrangement of the cut tobacco, the optimal effect can be achieved by adjusting and confirming the axial arrangement of the cut tobacco one by one according to steps on the premise of ensuring the quality of cigarettes.
Therefore, a further scheme can be obtained that the adjusting of the size of the secondary stalk removing air door 7 enables the material speed of the secondary stalk removing blanking port to be specifically included in the range of 80g/min to 86 g/min:
and adjusting the size of the secondary stalk removing air door 7, detecting whether the material speed of the secondary stalk removing stick blanking port is in the range of 80g/min to 86g/min, if so, stopping adjusting and entering the next step, and if not, returning to continue adjusting.
According to the above embodiment, the present application further provides a use case as follows: be applied to the cigarette machine that a certain high added value brand cigarette corresponds with this application, the cigarette machine malleation adopts 6 mbar. From the comparison of data before and after implementation, the physical indexes of the cigarette are kept stable, and the cigarette bundle is compact after the cigarette paper of the cigarette is peeled. Through the statistical data and the off-line detection of the weight control system, the result is as follows:
1. the rejection rate of the cigarette making machine waste products is controlled within 0.2 percent, is reduced by 0.15 percent compared with the average value of 0.35 percent before adjustment, and the rejection rate of cigarettes is reduced to a certain extent.
2. 40g of stalk filament materials are removed less every minute at the position where the stalk sticks are removed twice, so that the stalk sticks in the cigarettes are greatly reduced, and certain cost is saved for production.
