Description

Technical Field

[0001] The present application relates to the technical field of tobacco processing, and in particular to a ventilation rate control method, device, equipment, medium and program product. Background Art

[0002] The ventilation rate of cigarettes is one of the important indicators for process detection and quality verification, and is also one of the detection items randomly inspected by the National Bureau. The National Bureau ranks various cigarettes according to the compliance and stability of the ventilation rate verified and publishes them in the "Cigarette Product Quality Report". As an important means of regulating harmful components such as carbon monoxide in the mainstream smoke, for pre-punched cigarette products, how to stably control the ventilation rate of cigarettes has always been one of the difficulties and hotspots in the tobacco industry.

[0003] Existing research has found that the ventilation rate increases with the increase of cigarette quality and the width of the non-glue area of the rubber roller. It has also been found that when the operating speed of the cigarette machine increases, the wrap angle between the tipping paper and the glue applicator roller decreases, the glue application amount decreases, and the ventilation rate of the filter tip increases. However, the above research has the defect that there are few research factors, and the research is not comprehensive and systematic, resulting in difficulty in application in actual production, and it is difficult to quantitatively control the ventilation rate of cigarettes.

[0061] In order to make the objectives, technical solutions and advantages of the present application more clear, the following further details the present application in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0062] The ventilation rate control method provided by the embodiments of the present application can be applied to an application environment for regulating the ventilation rate of cigarettes before cigarette rolling. This method can be executed by a computer device, which can be a server or a terminal with powerful computing power.

[0063] In an exemplary embodiment, as Figure 1 shown, a ventilation rate control method is provided. Taking the application of this method to a server as an example, it specifically includes the following steps:

[0064] S101, when it is necessary to roll cigarettes, obtain the initial rolling strategy and the initial ventilation rate of the cigarettes rolled using the initial rolling strategy.

[0065] Among them, the initial rolling strategy is the strategy for rolling cigarettes. The initial rolling strategy includes, but is not limited to, dynamic influence parameters and static influence parameters that affect the ventilation rate. The dynamic influence parameters include the wrap angle and sizing parameters, and the static influence parameters include the blade attribute parameters of the blade used in the rolling process. The wrap angle is the angle of the contact wrap between the tipping paper and the sizing roller; the sizing parameters include, but are not limited to, the gap between the sizing roller and the glue control roller, the sizing thickness, the width of the lap glue, and the height of the glue-free area, etc. The blade attribute parameters include the paper scraping angle, the blade life, and the number of blades; the initial ventilation rate is the ventilation rate of the cigarettes rolled using the initial rolling strategy. The ventilation rate of a cigarette refers to the air flow rate passing through the cigarette within a certain period of time.

[0066] Optionally, one or more cigarettes can be rolled using the initial rolling strategy, and the ventilation rate of the rolled cigarettes can be tested by experimental testing methods as the initial ventilation rate. Exemplarily, the cigarettes can be placed under certain conditions, and the initial ventilation rate can be calculated by measuring the differential pressure at the inlet and outlet. The cigarettes can also be placed in a flow meter, and the initial ventilation rate can be calculated by measuring the air flow rate.

[0067] Optionally, to ensure the accuracy of the initial ventilation rate, multiple rolls can be performed to obtain a sufficient number of each cigarette, and the initial ventilation rate can be determined based on the mean value of the reference ventilation rates of the cigarettes rolled using the initial rolling strategy.

[0068] S102. Determine the ventilation rate adjustment amount according to the initial ventilation rate and the preset ventilation rate range.

[0069] Among them, the preset ventilation rate range is the pre-set value range of the ventilation rate that meets the regulations. For example, the preset ventilation rate range can be 20% - 30%. The ventilation rate adjustment amount is the amount that needs to adjust the initial ventilation rate so that the adjusted initial ventilation rate is within the preset ventilation rate range.

[0070] Generally, the preset ventilation rate range includes a minimum value and a maximum value. The mean value of the minimum value and the maximum value can be used as a reference value, and the difference between the reference value and the initial ventilation rate can be used as the ventilation rate adjustment amount. It can be understood that the ventilation rate adjustment amount can be a positive number or a negative number.

[0071] S103. Determine the target adjustment amounts of different influence parameters according to the ventilation rate adjustment amount and the influence information of different influence parameters on the ventilation rate.

[0072] Among them, the influence information of different influence parameters on the ventilation rate characterizes the influence of different influence parameters on the ventilation rate. In the embodiments of the present application, the influence information includes an influence direction and an influence amount. The influence direction includes positive correlation or negative correlation. If the influence direction is positive correlation, it indicates that the influence parameter is positively correlated with the ventilation rate. If the influence direction is negative correlation, it indicates that the influence parameter is negatively correlated with the ventilation rate. The influence amount is the maximum influence amount that the influence parameter can cause to the ventilation rate. The target adjustment amount of each influence parameter is the adjustment amount for the influence parameter. It can be understood that the target adjustment amount can be a positive number or a negative number.

[0073] Optionally, according to the influence degree of each influence parameter on the cigarette-making process, a priority level can be set for each influence parameter. The higher the priority level, the smaller the influence degree on the cigarette-making process. The lower the priority level, the greater the influence degree on the cigarette-making process. Therefore, the influence parameter with a higher priority level can be adjusted first.

[0074] Further, after sorting the priority levels of the influence parameters, according to the size relationship between the ventilation rate adjustment amount and 0, the adjustment direction is determined. For example, if the ventilation rate adjustment amount is less than 0, it indicates that the adjustment direction is to decrease. The influence parameter with a negative correlation can be increased, or the influence parameter with a positive correlation can be decreased. If the ventilation rate adjustment amount is greater than 0, it indicates that the adjustment direction is to increase. The influence parameter with a positive correlation can be increased, or the influence parameter with a negative correlation can be decreased. Therefore, through the above process, the target adjustment amount of each influence parameter can be determined. For the influence parameter that does not need to be adjusted, the corresponding target adjustment amount is 0.

[0075] S104. Adjust the initial rolling strategy according to the target adjustment amounts of different influence parameters to obtain the target cigarette-making strategy.

[0076] Among them, the ventilation rate of the cigarette rolled using the target cigarette-making strategy is within the preset ventilation rate range.

[0077] Optionally, the influence parameters in the initial rolling strategy can be adjusted according to the target adjustment amounts of different influence parameters to obtain the target cigarette-making strategy.

[0078] In the above ventilation rate control method, when it is necessary to roll cigarettes, an initial rolling strategy and the initial ventilation rate of the cigarettes rolled using the initial rolling strategy are obtained. Among them, the initial rolling strategy includes dynamic influence parameters and static influence parameters that affect the ventilation rate. The dynamic influence parameters include the wrap angle and sizing parameters, and the static influence parameters include the blade property parameters of the blade used in the rolling process. This is equivalent to comprehensively considering various influence parameters in the cigarette rolling process. Further, according to the initial ventilation rate and the preset ventilation rate range, the ventilation rate adjustment amount is determined. According to the ventilation rate adjustment amount and the influence information of different influence parameters on the ventilation rate, the target adjustment amount of different influence parameters is determined. Among them, the influence information includes the influence direction and the influence amount, and the influence direction includes positive correlation or negative correlation, which is equivalent to quantifying the influence of different influence parameters on the ventilation rate. According to the target adjustment amount of different influence parameters, the initial rolling strategy is adjusted to obtain the target cigarette rolling strategy, so as to ensure that the ventilation rate of the cigarettes rolled using the target cigarette rolling strategy is within the preset ventilation rate range, and the ventilation rate of the cigarettes can be accurately adjusted during the production process of the cigarettes.

[0079] Optionally, in order to more accurately determine the ventilation rate adjustment amount, it is stipulated that the preset ventilation rate range includes a preset minimum ventilation rate and a preset maximum ventilation rate. In an exemplary embodiment, a method for determining the ventilation rate adjustment amount is provided: when the initial ventilation rate is less than the preset minimum ventilation rate, the difference between the initial ventilation rate and the preset minimum ventilation rate is used as the ventilation rate adjustment amount. Among them, the preset minimum ventilation rate is the lower limit of the preset ventilation range.

[0080] Optionally, if the initial ventilation rate is less than the preset minimum ventilation rate, it means that the initial ventilation rate needs to be increased so that the initial ventilation rate is within the preset ventilation rate range. Therefore, in order to ensure the positive and negative of the ventilation rate adjustment amount, the difference between the initial ventilation rate and the preset minimum ventilation rate can be used as the ventilation rate adjustment amount. At this time, the ventilation rate adjustment amount is a positive number, that is, greater than 0.

[0081] Optionally, when the initial ventilation rate is greater than the preset maximum ventilation rate, the difference between the preset maximum ventilation rate and the initial ventilation rate is used as the ventilation rate adjustment amount. Among them, the preset minimum ventilation rate is the lower limit of the preset ventilation range. Optionally, if the initial ventilation rate is greater than the preset maximum ventilation rate, it means that the initial ventilation rate needs to be decreased so that the initial ventilation rate is within the preset ventilation rate range. Therefore, in order to ensure the positive and negative of the ventilation rate adjustment amount, the difference between the preset maximum ventilation rate and the initial ventilation rate can be used as the ventilation rate adjustment amount. At this time, the ventilation rate adjustment amount is a negative number, that is, less than 0.

[0082] Optionally, in order to ensure the accuracy of the influence information of different influence parameters on the ventilation rate, in one embodiment, such as Figure 2As shown, a method for determining the influence information of different influencing parameters on the ventilation rate is provided, which specifically includes the following steps:

[0083] S201, for any influencing parameter, obtain the sample ventilation rates of the influencing parameter at different values.

[0084] Among them, the sample ventilation rate of the influencing parameter at each value is the sample ventilation rate of the cigarette rolled under the condition that other influencing parameters are preset values and the influencing parameter is at the value.

[0085] Optionally, for any influencing parameter, the control variable method can be used to conduct multiple cigarette rolling tests, and based on the cigarettes obtained from the tests, calculate the sample ventilation rates of the influencing parameter at different values.

[0086] S202, determine the influence information of the influencing parameter on the ventilation rate according to the sample ventilation rates of the influencing parameter at different values.

[0087] Exemplarily, for the influencing parameter of the wrapping angle, all influencing parameters except the wrapping angle can be controlled to take preset values and remain unchanged, and the wrapping angle is continuously changed. The ventilation rate data of the cigarettes after rolling with different wrapping angles are shown in Table 1. It can be seen from Table 1 that within the normal rolling range, as the wrapping angle increases, the ventilation rate increases. This is because as the wrapping angle increases, the contact area and pressure between the tipping paper and the rubber roller decrease, and thus the glue decreases, resulting in an increase in the ventilation rate. However, when the wrapping angle increases to 168°, due to too little glue, it affects the adhesion of the tipping paper, causing defective cigarettes such as wrinkles, openings, and air leakage. Therefore, it can be concluded that the influence direction of the wrapping angle on the ventilation rate is positively correlated, and the wrapping angle can be adjusted within the range of 158° to 163°, and the influence amount on the ventilation rate is approximately 1.7%.

[0088] Table 1 Mean ventilation rate of cigarettes rolled with different wrapping angles

[0089]

[0090] Regarding the influencing parameter of the gap between the sizing roller and the glue control roller, all influencing parameters except the gap between the sizing roller and the glue control roller can be controlled to take preset values and remain unchanged. By continuously changing the gap between the sizing roller and the glue control roller, the changes in the cigarette ventilation rate after fine-tuning the gap between the sizing roller and the glue control roller are shown in Table 2. Through variance analysis of the data, it can be obtained that the P-values between any two of "increased, normal, decreased" are less than 0.01, and the mean ventilation rate: increased < normal < decreased, indicating that the ventilation rate decreases with the increase in the gap between the sizing roller and the glue control roller. Therefore, it can be concluded that the influencing direction of the gap between the sizing roller and the glue control roller on the ventilation rate is negatively correlated, and the gap between the sizing roller and the glue control roller can be fine-tuned within the normal range, with an influence on the ventilation rate of approximately 2%. Among them, the P-value characterizes the degree of difference between two sets of data. If P < 0.01, it indicates that there is a significant difference between the two sets of data.

[0091] Table 2 Mean ventilation rates corresponding to different gaps between the sizing roller and the glue control roller

[0092]

[0093] Regarding the influencing parameter of the sizing thickness, all influencing parameters except the sizing thickness can be controlled to take preset values and remain unchanged. By continuously changing the sizing thickness, the mean ventilation rates for different sizing thicknesses are shown in Table 3. Through variance analysis of the data, it can be seen that the ventilation rate decreases with the increase in the sizing thickness, and the tipping quality is good for sizing thicknesses from 0.02 mm to 0.035 mm. Therefore, it can be concluded that the influencing direction of the sizing thickness on the ventilation rate is negatively correlated, and the recommended value of the sizing thickness is (0.02 - 0.035) mm, with an influence on the ventilation rate of approximately 3.3%.

[0094] Table 3 Mean ventilation rates for different sizing thicknesses

[0095]

[0096] Regarding the influencing parameter of the lap joint glue width, all influencing parameters except the lap joint glue width can be controlled to take preset values and remain unchanged. By continuously changing the lap joint glue width, the mean ventilation rates for different lap joint glue widths are shown in Table 4. All three sets of data meet the requirements of normal distribution and homogeneity of variance tests. Using the assumed equal variance LSD (Least Significant Difference) test, the P-values between any two are all less than 0.01, indicating significant differences. The mean ventilation rate: 7 mm < 5 mm < 4 mm, indicating that the larger the lap joint glue width, the smaller the ventilation rate, and the tipping quality of the glue rollers is qualified for lap joint glue widths from 7 mm to 4 mm. Therefore, it can be concluded that the influencing direction of the lap joint glue width on the ventilation rate is negatively correlated, and the tipping quality of the glue rollers is qualified for lap joint glue widths from 7 mm to 4 mm. The influence on the ventilation rate is approximately 3.8%.

[0097] Table 4 Mean ventilation rates for different lap joint glue widths

[0098]

[0099] Regarding the influencing parameter of the height of the non - adhesive area, all influencing parameters except the height of the non - adhesive area can be controlled to take preset values and remain unchanged. By continuously changing the height of the non - adhesive area, the average ventilation rates for different heights of the non - adhesive area are shown in Table 5. It can be seen that for the non - adhesive area heights of 8mm and 9mm, and 9mm and 10mm, P > 0.05, indicating no significant difference; for 8mm and 10mm, P < 0.05, showing a difference. The average ventilation rates are: 8mm < 9mm < 10mm. The difference in ventilation rates between 8mm and 10mm is 2.2%, and there are no tipping problems in both cases. The ventilation rate can be directionally regulated by adjusting the height of the non - adhesive area. Therefore, it can be concluded that the influence direction of the height of the non - adhesive area on the ventilation rate is positively correlated, and it can be adjusted between 8mm and 10mm, with an influence amount on the ventilation rate of approximately 2.2%.

[0100] Table 5 Average ventilation rates for different heights of the non - adhesive area

[0101]

[0102] Regarding the influencing parameter of the scraping angle, all influencing parameters except the scraping angle can be controlled to take preset values and remain unchanged. By continuously changing the scraping angle, the average ventilation rates for different scraping angles are shown in Table 6. The results of variance analysis show that for 80° and 84°, and 80° and 88°, P < 0.01, indicating a significant difference; for 84° and 88°, P > 0.05, showing no significant difference. The average ventilation rates are: 80° < 84°, 88°. This is because when the scraping angle is reduced, the pressure between the scraping knife and the tipping paper increases, and the degree of scraping hair increases, which helps the tipping paper to bond better and the ventilation rate to decrease. Therefore, it can be concluded that the influence direction of the scraping angle on the ventilation rate is positively correlated, and it can be adjusted between 80° and 88°, with an influence amount on the ventilation rate of approximately 1.7%.

[0103] Table 6 Average ventilation rates for different scraping angles

[0104]

[0105] Regarding the influencing parameter of the scraper life, all influencing parameters except the scraper life can be controlled to take preset values and remain unchanged. By continuously changing the scraper life, the average ventilation rates for different scraper lives are obtained as shown in Table 7. The results of the variance analysis show that P < 0.05 for the average ventilation rates of the new and old scrapers, indicating a significant difference. The average ventilation rate: old scraper < new scraper, and the new scraper has a 2.2% higher ventilation rate than the old scraper. To explain the difference between the new and old scrapers, the water absorbency of the tipping paper after scraping by the new and old scrapers was measured. The water absorbency (T95 / s) of the tipping paper of three groups of new and old scrapers was measured respectively. The smaller the T95 / s, the better the water absorbency. For the new scraper, T95 / s: 0.085, 0.088, 0.089; for the old scraper, T95 / s: 0.056, 0.058, 0.73. It can be seen that the T95 / s of the new scraper > the T95 / s of the old scraper, indicating that the tipping paper after scraping by the old scraper has better water absorbency, is more likely to absorb glue, and has a smaller ventilation rate. Therefore, it can be concluded that the influence direction of the scraper life on the ventilation rate is positively correlated, and the influence amount on the ventilation rate is approximately 2.2%.

[0106] Table 7 Average ventilation rates for different scraper lives

[0107]

[0108] Regarding the influencing parameter of the number of scrapers, all influencing parameters except the number of scrapers can be controlled to take preset values and remain unchanged. By continuously changing the number of scrapers, the average ventilation rates for different numbers of scrapers are obtained as shown in Table 8. The ventilation rate of 1 scraper handle is significantly greater than that of 2 scraper handles, and the mean difference is 2.9. The scraper can scrape the tipping paper thin and fluffy because the two scrapers have a greater degree of fluffing the tipping paper, which is beneficial for gluing the tipping paper and the diffusion of glue on the tipping paper. Therefore, it can be concluded that the influence direction of the number of scrapers on the ventilation rate is negatively correlated, and the influence amount on the ventilation rate is approximately 2.9%.

[0109] Table 8 Average ventilation rates for different numbers of scrapers

[0110]

[0111] In this embodiment, through multiple experiments, the sample ventilation rates for each influencing parameter at different values are calculated and analyzed, ensuring the accuracy of the influence information of the determined influencing parameters on the ventilation rate.

[0112] In addition, in addition to the influencing parameters described in the above embodiments, the tipping paper used for cigarettes, the leaf group formula, and the cleanliness of the tools used will also affect the ventilation rate of cigarettes.

[0113] For example, cleaning and maintenance of rubber rollers, gears and their channels can be carried out, and the mean ventilation rate before and after 10 cleanings is shown in Table 9. The data does not meet the variance homogeneity test, so the Tamheni T2 test without assuming equal variance is used. It can be seen that the ventilation rate increases significantly after maintenance compared with before maintenance, but not all cleaning and maintenance are effective. It is only effective when the dirt on rubber rollers, gears, etc. affects the quality of cigarette splicing. Therefore, equipment cleaning and maintenance should be carried out regularly according to the equipment usage status to ensure that the equipment is in normal condition.

[0115]

[0116] The ventilation rate data of Gaoyou and Jinling tipping papers are shown in Table 10. It can be seen that the ventilation rate of Jinling tipping paper is significantly greater than that of Gaoyou, with a difference of 3.1. In order to explain this long-standing difference in the rolling process, the air permeability and contact angle of Gaoyou and Jinling tipping papers were measured. The average ventilation rate of tipping papers without and with scrapers is shown in Table 11. Among them, Gaoyou and Jinling have significant differences in air permeability (P < 0.01), and the average air permeability is: Gaoyou > Jinling. There is no significant difference in air permeability between Gaoyou and Jinling tipping papers without and with scrapers (P > 0.05), which shows that whether or not the tipping paper is scraped does not affect the air permeability of the tipping paper. It is generally believed that air permeability contributes to ventilation rate, so the difference in air permeability between Gaoyou and Jinling in this study is not the main reason for the difference in ventilation rate. In terms of water absorption, the T95 / s of three groups of Gaoyou and Jinling tipping papers were measured respectively. Gaoyou T95 / s: 0.126, 0.121, 0.109, Jinling T95 / s: 0.066, 0.063, 0.066. It can be seen that Gaoyou T95 / s> Jinling T95 / s, and the smaller the T95 / s, the better the water absorption, that is, water absorption: Gaoyou < Jinling. This may be because the water absorption is good, the amount of glue applied is more and more uniform, and the ventilation rate of the cigarette is reduced.

[0121] In addition, the ventilation rate test data of Jiaozi (X) in 2023 were summarized and analyzed, and the results are shown in Table 12. The total ventilation trend chart of Jiaozi (X) is as follows Figure 3As shown, it can be seen that there are obvious inflection points in the average ventilation rate three times in 2023, which are January 8th, February 21st, and June 24th respectively. Statistical data analysis shows that the change in the average ventilation rate exceeds 3%. Tracing the formula change time shows that the time when the inflection point of the ventilation rate appears is consistent with the time of the leaf group formula adjustment, and the time difference is within 1 day, indicating that the cigarette formula is closely related to the ventilation rate, and the change in the cigarette formula may cause a large deviation in the average ventilation rate.

[0124] Optionally, in one embodiment, as Figure 4 shown, a method for determining the target adjustment amount of different influence parameters is provided, which specifically includes the following steps:

[0125] S401. According to the influence information of different influence parameters on the ventilation rate, construct a comprehensive function relationship between the ventilation rate and different influence parameters.

[0126] Among them, the comprehensive function relationship characterizes the comprehensive influence of all influence parameters on the ventilation rate.

[0127] Optionally, since the influence information of each influence parameter on the ventilation rate includes the influence direction and the influence amount, the influence degree of each influence parameter on the ventilation rate can be evaluated according to the influence amount, and a weight is assigned to each influence parameter according to the influence degree. For example, if the influence degree on the ventilation rate is higher, the weight is higher.

[0128] Furthermore, based on the weights of the influence parameters, as well as the influence direction and the influence amount, construct a comprehensive function relationship between the ventilation rate and different influence parameters.

[0129] Exemplarily, the comprehensive function relationship can be expressed as:

[0130]

[0131] Among them, is the adjustment amount of the ventilation rate under the influence of each influence parameter; is the number of influence parameters; is the weight of the th influence parameter; represents the influence direction of the th influence parameter. If the influence direction is positively correlated, then ; if the influence direction is negatively correlated, then ; is the influence amount of the th influence parameter on the ventilation rate; is the The adjustment amount of an influencing parameter, which is an unknown variable.

[0132] S402. Take the difference between the ventilation rate adjustment amount and the comprehensive function relationship as the objective function.

[0133] Optionally, the difference between the ventilation rate adjustment amount and the comprehensive function relationship characterizes the gap between the adjusted ventilation rate after adjusting each influencing parameter and the desired ventilation rate adjustment amount. Therefore, the difference between the ventilation rate adjustment amount and the comprehensive function relationship can be taken as the objective function.

[0134] S403. Determine the constraint functions of different influencing parameters according to the preset parameter ranges of different influencing parameters.

[0135] It can be understood that during the cigarette rolling process, each influencing parameter has a specified optimal value range. For example, for the wrapping angle, the preset parameter range can be 158 - 163.

[0136] Furthermore, the constraint functions of each influencing parameter can be constructed according to the preset parameter ranges of different influencing parameters.

[0137] S404. With the goal of minimizing the function value of the objective function and using the constraint functions of different influencing parameters as constraint conditions, solve the objective function to obtain the target adjustment amounts of different influencing parameters.

[0138] Optionally, the minimum function value of the objective function indicates that the adjusted ventilation rate will be closer to the preset ventilation rate range. Therefore, an optimization algorithm can be used to solve the objective function with the goal of minimizing the function value of the objective function and using the constraint functions of different influencing parameters as constraint conditions to obtain the target adjustment amounts of different influencing parameters.

[0139] In this embodiment, through the comprehensive function relationship, it is ensured that the constructed objective function can accurately characterize the degree to which the adjusted ventilation rate is close to the preset ventilation rate range. Furthermore, it is ensured that after adjusting according to the determined target adjustment amounts of different influencing parameters, the ventilation rate of the cigarette is closer to the preset ventilation rate range.

[0144] S503. Determine the ventilation rate adjustment amount according to the initial ventilation rate and the preset ventilation rate range.

[0145] Among them, the preset ventilation rate range includes a preset minimum ventilation rate and a preset maximum ventilation rate.

[0146] Optionally, when the initial ventilation rate is less than the preset minimum ventilation rate, the difference between the initial ventilation rate and the preset minimum ventilation rate is used as the ventilation rate adjustment amount; when the initial ventilation rate is greater than the preset maximum ventilation rate, the difference between the preset maximum ventilation rate and the initial ventilation rate is used as the ventilation rate adjustment amount.

[0147] S504. Construct a comprehensive function relationship between the ventilation rate and different influence parameters according to the influence information of different influence parameters on the ventilation rate.

[0148] Optionally, the influence information of different influence parameters on the ventilation rate is constructed in the following way: for any influence parameter, obtain the sample ventilation rate of the influence parameter at different values; among them, the sample ventilation rate of the influence parameter at each value is the sample ventilation rate of the cigarette rolled when other influence parameters are preset values and the influence parameter is at the value; according to the sample ventilation rates of the influence parameter at different values, determine the influence information of the influence parameter on the ventilation rate.

[0150] Optionally, the influence direction of the wrap angle on the ventilation rate is positively correlated; the influence direction of the gap between the sizing roller and the glue control roller on the ventilation rate is negatively correlated; the influence direction of the sizing thickness on the ventilation rate is negatively correlated; the influence direction of the width of the lap joint glue on the ventilation rate is negatively correlated; the influence direction of the height of the glue-free area on the ventilation rate is positively correlated; the influence direction of the blade scraping angle on the ventilation rate is positively correlated; the influence direction of the blade life on the ventilation rate is positively correlated; the influence direction of the number of blades on the ventilation rate is negatively correlated.
