[0001] The present invention relates to the field of tobacco processing technology, and in particular to a method, apparatus, equipment and storage medium for determining the working parameters of an air classifier. Background Technology

[0002] On existing cigarette manufacturing lines, air classifiers are key equipment for removing stems, dust, and other impurities from tobacco shreds. The current conventional approach involves operators manually adjusting the frequency converters of the dust collector and circulating fan in the air classifier based on experience and the brand number on the production plan.

[0003] The shortcomings of the existing technology are as follows: 1. Different experience of the operators leads to inconsistent adjustment parameters, which affects the quality of air separation.

[0004] 2. Response lag: When switching between multiple brands frequently, manual adjustment often lags behind production start-up, resulting in unstable tobacco processing quality in the initial stage of switching.

[0005] 3. The "one-size-fits-all" problem: Existing automated control often uses a single fixed frequency parameter, which cannot adapt to the huge differences in physical properties between "slim cigarettes" (strong filling force, fragile) and "conventional cigarettes", leading to contradictions such as breakage or incomplete impurity removal during the production of slim cigarettes.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The acquisition, storage, use, and processing of data in the technical solutions of the embodiments of the present invention all comply with the relevant provisions of national laws and regulations.

[0014] Figure 1 This is a flowchart of a method for determining the working parameters of an air classifier according to an embodiment of the present invention. The embodiment of the present invention can be applied to scenarios in which the parameters of an air classifier are configured during the tobacco processing. The method can be executed by an air classifier working parameter determining device, which can be implemented by software and / or hardware.

[0015] like Figure 1 As shown, the method for determining the operating parameters of an air classifier includes the following steps: S110. Obtain tobacco production plan information.

[0016] The tobacco production plan information can be about the planned processing and production of the target tobacco. Specifically, the tobacco production plan information can include the attribute information and corresponding production plan information for each batch of tobacco. Furthermore, the tobacco production plan information can be obtained through upstream and downstream systems, or it can be obtained through manual input.

[0017] S120. Based on the tobacco production plan information, determine the target tobacco type corresponding to each batch of target tobacco.

[0018] The target tobacco type can be used to represent the type of tobacco corresponding to a target batch. The target tobacco type includes at least two categories: regular tobacco and slim cigarettes. Specifically, based on the tobacco production plan information, the identification information corresponding to each target batch of tobacco can be determined, and the corresponding target tobacco type can be obtained by matching the identification information of the target batch of tobacco.

[0019] S130. For each batch of target tobacco shreds, determine the corresponding working frequency of the air classifier based on the type of target tobacco shreds, and control the frequency converter of the target air classifier based on the working frequency of the air classifier.

[0020] The target air separator can be a device used to separate materials from a target batch of tobacco. Specifically, the target air separator may include a dust removal fan and a circulating fan. The operating frequency of the air separator can be the operating frequency of the target air separator during the tobacco processing of the target batch of tobacco. Specifically, the corresponding operating frequency of the air separator can be determined based on the type of target tobacco. Furthermore, the operating frequency of the air separator can be sent to the frequency converter of the target air separator, so that the frequency converter adjusts the operating frequency of the target air separator to the air separator's operating frequency, and performs material separation of the target batch of tobacco based on the adjusted operating frequency.

[0021] The technical solution provided by this invention involves acquiring tobacco production plan information; determining the target tobacco type for each batch of target tobacco based on the production plan information; wherein the target tobacco type includes at least: conventional tobacco and slim tobacco; for each batch of target tobacco, determining the corresponding air classifier operating frequency based on the target tobacco type, and controlling the frequency converter of the target air classifier based on the air classifier operating frequency. This invention solves the problem of unstable air classifier quality caused by lag in manual adjustment and fixed parameters in existing tobacco processing technologies. It can determine the tobacco type for each batch of tobacco based on production plan information and automatically match and determine the corresponding air classifier operating frequency based on the tobacco type, thereby improving the efficiency and batch stability of tobacco air classifier.

[0022] Figure 2 This is a flowchart of another method for determining the working parameters of an air classifier provided by an embodiment of the present invention. This embodiment of the present invention can be applied to scenarios where the parameters of an air classifier are configured during the tobacco processing. Based on the above embodiments, this embodiment further explains how to determine the target tobacco type corresponding to each batch of target tobacco based on tobacco production plan information; and how to determine the corresponding air classifier working frequency based on the target tobacco type, and control the frequency converter of the target air classifier based on the air classifier working frequency. This device can be implemented by software and / or hardware and integrated into a computer device with application development capabilities.

[0023] like Figure 2 As shown, the method for determining the operating parameters of an air classifier includes the following steps: S210. Obtain tobacco production plan information.

[0024] The tobacco production plan information can be about the planned processing and production of the target tobacco. Specifically, the tobacco production plan information can include the attribute information and corresponding production plan information for each batch of tobacco. Furthermore, the tobacco production plan information can be obtained through upstream and downstream systems, or it can be obtained through manual input.

[0025] S220. For each batch of target tobacco shreds, determine the tobacco production grade information corresponding to the target batch of tobacco shreds from the tobacco shreds production plan information.

[0026] The target batch of tobacco can be any batch of tobacco for which processing and production parameters need to be configured. Specifically, each batch of tobacco involved in the tobacco production plan information can be considered as the target batch. The tobacco production grade information can be the attribute information describing the tobacco in the target batch. Specifically, the tobacco production plan information can contain the production grade information corresponding to each target batch of tobacco, and the corresponding tobacco production grade information for the target batch can be extracted from the tobacco production plan information based on appropriate data extraction algorithms.

[0027] S230. Determine the target tobacco type corresponding to the target batch of tobacco based on the tobacco production grade information and the preset tobacco type relationship.

[0028] The preset tobacco type relationship represents the mapping between tobacco production grades and tobacco types. The target tobacco type represents the tobacco type corresponding to a target batch of tobacco. The target tobacco type includes at least two categories: regular tobacco and slim cigarettes. Specifically, the tobacco type corresponding to the production grade of the target batch of tobacco can be determined based on the preset tobacco type relationship, and this determined tobacco type is used as the target tobacco type.

[0029] S240. Based on the mapping relationship between the target tobacco type and the preset frequency, determine the working frequency of the dust removal fan and the working frequency of the circulating fan.

[0030] The preset frequency mapping relationship represents the mapping between tobacco type and the reference frequency of the air separator. Specifically, the preset frequency mapping relationship can be manually set; users can set the corresponding reference frequency for the air separator for different types of tobacco according to material separation requirements. The dust collector fan's operating frequency can be the reference frequency for dust removal of the target batch of tobacco. The circulating fan's operating frequency can be the reference frequency for operation of the circulating fan for the target batch of tobacco.

[0031] For example, upon receiving a reference frequency adjustment command, the reference frequency adjustment interface of the wind separator can be displayed on a preset interactive interface; in response to user interaction on the reference frequency adjustment interface of the wind separator, the reference frequency of the wind separator corresponding to the type of tobacco to be adjusted can be adjusted.

[0032] The reference frequency adjustment command can be a trigger command used to adjust the reference frequency of the air separator for tobacco. Specifically, the user can click the corresponding reference frequency adjustment control on the interactive interface to issue a reference frequency adjustment command. Upon receiving the command, the device displays the air separator reference frequency adjustment interface on a preset interactive interface. Furthermore, the user can perform interactive operations on the air separator reference frequency adjustment interface, and the device will then adjust the air separator reference frequency corresponding to the type of tobacco to be adjusted (the type of tobacco selected by the user through interactive operations) according to the user's interaction.

[0033] S250: Control the frequency converter of the target air classifier based on the operating frequency of the air classifier.

[0034] The target air separator can be a device used to separate materials from a target batch of tobacco. Specifically, the target air separator may include a dust removal fan and a circulating fan. Furthermore, the operating frequency of the air separator can be sent to the frequency converter of the target air separator, so that the frequency converter adjusts the operating frequency of the target air separator to the air separator's operating frequency, and performs material separation on the target batch of tobacco based on the adjusted operating frequency.

[0035] Optionally, during the processing of the target batch of tobacco shreds based on the working frequency of the air classifier, the moisture content and feed flow rate of the target batch of tobacco shreds can be obtained at preset intervals; the fine-tuning amount of the air classifier can be determined based on the moisture content and feed flow rate; and the working frequency of the air classifier can be adjusted based on the fine-tuning amount of the air classifier.

[0036] The preset cycle can be a pre-set cycle used to fine-tune the operating frequency of the air separator. The tobacco moisture parameter can be a parameter representing the moisture content of the tobacco. Specifically, a corresponding moisture detection sensor can be installed at the tobacco processing outlet to detect the moisture content of the processed tobacco and obtain the tobacco moisture parameter. The feed flow rate parameter can be a parameter representing the input flow rate at the tobacco processing inlet. Specifically, a corresponding flow sensor can be installed at the tobacco processing inlet to detect the flow rate of the input tobacco, thereby obtaining the feed flow rate parameter.

[0037] Furthermore, the fine-tuning amount of the air classifier can be an adjustment amount used to correct the operating frequency of the air classifier. Specifically, a mapping relationship between the tobacco moisture content parameter, the incoming material flow rate parameter, and the fine-tuning amount can be preset. Then, based on this mapping relationship, the corresponding air classifier fine-tuning amount is obtained by matching the tobacco moisture content parameter and the incoming material flow rate parameter. Finally, the air classifier fine-tuning amount can be added to the current air classifier operating frequency to achieve real-time adjustment of the air classifier's operating frequency.

[0038] The following is an example of the automatic frequency fine-tuning process of an air separator: First, the baseline operating conditions are established: when the moisture content of the incoming tobacco shreds is stable at the process standard value of 13.2% and the incoming material conveying flow rate is stable at the rated value of 6000 kg / h, the air classifier blower operates at the baseline frequency x. At this time, the air velocity in the air classifier chamber exactly matches the difference in suspension velocity between the tobacco shreds and the stems, which can ensure that the stems and impurities are fully settled and removed without causing excessive loss of qualified tobacco shreds. This is the optimal operating condition for air classifier effect.

[0039] During formal production, the system collects real-time data on the moisture content and flow rate of the incoming material using an online moisture meter and electronic belt scale installed at the feed end of the air separator. It also calculates material delay based on the belt conveyor speed to ensure that the detected data perfectly matches the material just entering the air separator chamber, preventing misalignment of adjustment timing. Subsequently, the system calculates frequency correction amounts from both moisture and flow rate dimensions. (1) Core adjustments in the moisture dimension Moisture content is the most significant factor affecting air separation efficiency: the higher the moisture content of the tobacco, the greater its weight, and the higher the air velocity required to suspend it; conversely, the lower the moisture content, the lighter the tobacco, and the lower the required air velocity. If the air velocities are mismatched, either high moisture content will cause qualified tobacco to be discharged along with the stems, resulting in losses, or low moisture content will cause the lightweight stems to be carried into the finished product, affecting its purity.

[0040] Therefore, the system adopts a linear positive correlation adjustment rule: with 13.2% as the moisture content benchmark, for every 0.1% increase in moisture content above the benchmark value, the fan frequency is increased by 1Hz based on the benchmark x; for every 0.1% decrease in moisture content below the benchmark value, the fan frequency is decreased by 1Hz.

[0041] Simultaneously, upper and lower limits for adjustment are set: when the moisture content fluctuation is within the allowable range of ±0.5%, the frequency correction amplitude strictly corresponds to ±5Hz, changing linearly with the moisture deviation; if the incoming material moisture content exceeds the fluctuation range of ±0.5%, the fan frequency will no longer increase or decrease, and will be maintained at the limit value of x+5Hz or x-5Hz respectively, while triggering a production warning to prompt the front-end process to adjust the incoming material moisture content in a timely manner to avoid the air separation effect continuously deviating from the process requirements.

[0042] (2) Auxiliary correction of traffic dimension Fluctuations in the incoming material flow rate will change the material concentration and air resistance within the air separator: when the flow rate increases, the material inside the chamber becomes denser, the overall air resistance increases, and the actual effective air velocity decreases; when the flow rate decreases, the material becomes sparser, and the effective air velocity relatively increases. Therefore, the flow rate is used as an auxiliary adjustment factor to make a small correction to the frequency.

[0043] The adjustment rule is also linearly positively correlated: with a flow rate benchmark of 6000 kg / h, within the rated fluctuation range of ±60 kg / h, for every 60 kg / h deviation of the flow rate from the benchmark, the corresponding frequency is corrected by ±1 Hz, meaning the maximum correction range for the flow rate dimension is ±1 Hz. If the flow rate fluctuation exceeds this range, the frequency maintains the limit correction value and triggers a flow anomaly warning to prevent sudden changes in equipment load from affecting operational stability.

[0044] (3) Overall output and smooth execution The system combines the moisture correction and flow correction to obtain the final target operating frequency. To avoid frequent fan speed adjustments and reduced equipment lifespan due to small fluctuations in incoming material, the system is equipped with a dual stabilization mechanism: First, adjust the dead zone: when the moisture deviation is less than 0.05% and the flow deviation is less than 6 kg / h, it is judged as a normal small fluctuation, and the frequency is not adjusted for the time being; Second, smooth transition: When the frequency needs to be adjusted, a gradual approach is adopted, with an adjustment step of no more than 0.5Hz per second, to ensure that the fan speed changes smoothly and there will be no sudden increase or decrease.

[0045] Optionally, during the processing of the target batch of tobacco shreds based on the working frequency of the air classifier, the processing status information of the target batch of tobacco shreds can also be displayed on the corresponding work monitoring interface to achieve real-time monitoring of the current processing status of the target batch of tobacco shreds. The processing status information includes at least one of the following: the current type of tobacco shreds being processed, the target value of the air classifier frequency, the actual value of the air classifier frequency, and the air classifier alarm status.

[0046] Optionally, the amount of stems removed and the amount of shredded material in the stems can be counted separately after each batch of target tobacco is processed. Based on the amount of stems removed and the amount of shredded material in the stems of multiple target tobacco batches, the trend information of the processing status change can be determined and sent to the target tobacco processing management terminal.

[0047] The amount of stems removed can be the weight of stems removed after processing the target batch of tobacco. The shred content in the stems can be the shred content of tobacco in the removed stems. The processing status change trend information can be used to represent the changing trend of the stability of the tobacco processing status. Specifically, the amount of stems removed and the shred content in the stems corresponding to each batch of target tobacco can be sorted according to the processing order, then the sorted data can be fitted, and processing status analysis can be performed based on the fitted curve data to determine the processing status change trend information. For example, if the amount of stems removed and the shred content in the stems are stable within a certain range, the processing status change trend can be determined to be in a stable processing stage; if the amount of stems removed and the shred content in the stems fluctuate drastically, the processing status change trend can be determined to be an abnormal fluctuation. Furthermore, the abnormal fluctuation points and corresponding suspected causes of fluctuation can be determined based on the specific data changes.

[0048] Finally, the information on the changing trends of the processing status can be sent to the target processing management terminal so that managers can keep abreast of the changes in the tobacco processing status and make corresponding adjustments based on the changing trends, thereby improving the stability and efficiency of tobacco processing.

[0049] For example, in order to better understand the technical solution provided by the present invention, specific embodiments are described below: 1. Establish a dual-condition parameter recipe library (UDT): In the PLC program, a user-defined data type (UDT) is created to build a parameter formula library for the air separator. This formula library sets different control parameters for different types of tobacco, specifically divided into two operating conditions: Operating Condition A (Normal Smoke): Set the reference frequency of the dust removal fan (e.g., 45Hz) and the reference frequency of the circulating fan (e.g., 35Hz) for normal smoke.

[0050] Operating Condition B (Slim Smoke): Set the reference frequency of the dust removal fan (e.g., 38Hz-42Hz, preferably 40Hz) and the reference frequency of the circulating fan (e.g., 30Hz-34Hz, preferably 32Hz) corresponding to the slim smoke.

[0051] 2. Tobacco Category Identification and Signal Triggering: Obtain production plan information or brand signals issued by the upstream central control system.

[0052] Determine whether the current production brand belongs to "regular cigarettes" or "slim cigarettes".

[0053] 3. Automatic parameter adaptation and output: When the production is determined to be "regular smoke", the PLC automatically calls the parameters of working condition A and outputs the corresponding frequency command to the frequency converter of the dust removal fan and the circulating fan through the analog module or communication method.

[0054] When the system determines that "slim cigarettes" are being produced, the PLC automatically calls up the parameters of operating condition B and outputs the corresponding frequency command.

[0055] 4. Human-Machine Interface (HMI) Monitoring: The processing status information (including the current operating condition (A / B), target frequency, actual feedback frequency, and alarm status) is displayed on the touchscreen. For example, Figure 3 This is a diagram showing the processing status information of conventional tobacco according to an embodiment of the present invention. Figure 4 This is a display interface diagram of the processing status information corresponding to a slim cigarette according to an embodiment of the present invention.

[0056] Compared with the prior art, the present invention has the following significant advantages: 1. Precise Improvement in Product Quality: The pass rate of impurity removal for conventional tobacco shreds remains consistently above 99.5%, and the amount of impurities remaining in fine tobacco shreds is significantly reduced; automatic frequency reduction and shutdown when there is no material to wait for, completely eliminating the energy waste of the blower running idle; during the production process, the air separation frequency can be automatically fine-tuned according to the moisture content of the tobacco shreds and the flow rate of the incoming material, effectively offsetting the impact of moisture fluctuations on the air separation effect; after the HXD back-end air separation and impurity removal effect is enhanced, the amount of secondary air separation before rolling is reduced, the loss of qualified tobacco shreds and energy consumption are greatly reduced, and the consumption indicators return to the assessment standards; the amount of tobacco stem and tobacco stick residue is reduced, and the puncture rate of cigarettes is reduced to an extremely low level, achieving the dual goals of reducing consumption and ensuring quality.

[0057] Sampling results: Sampling was conducted from two main categories: regular tobacco and slim tobacco. The removal of stems from the air-separation process of Nanjing (Twelve Beauties) slim cigarettes was verified. Four batches were sampled and the amount of material removed during air-separation was tested. The removal weight of each batch was between 9.5 kg and 10.5 kg, which is 4.3 kg higher than the original average.

[0058] Verification was conducted on the removal of stems from the wind-separation process of normal Yansu tobacco (Five-Star Red Cedar). Four batches were sampled and tested for the amount of material removed during wind separation. The weight of material removed from each batch was between 5.0 kg and 6.5 kg, which is 1.5 kg higher than the previous average. The weight of tobacco shreds contained in the stems was 72 g per batch, which is better than the previous 85 g per batch.

[0059] For example, Figure 5 This is a comparison diagram showing the effects before and after implementing the method for determining the working parameters of an air separator according to an embodiment of the present invention. The left side shows the processing effect before application, and the right side shows the processing effect after application. Before application: When the air volume is low, the tobacco content in the stem sticks is high; when the air volume is high, the number of fallen stem sticks decreases; After application: The amount of stem sticks removed increases, while the tobacco content decreases.

[0060] 2. Significantly improved production efficiency: Manual parameter adjustment is eliminated. The distance between the operator and the air separator is about 50 meters. Previously, each batch of parameter adjustment took 15 minutes, with 8 batches per day. Now, it saves 1 person-time and about 2 hours of work time per day. Human error is eliminated, and switching efficiency and batch stability are improved.

[0061] 3. Enhanced intelligent adaptation capabilities: Achieves an intelligent closed loop of "operating condition recognition - automatic parameter adaptation", with full linkage between the air separation equipment and the tobacco production product category, moisture, and flow signals, meeting the requirements of "less manpower and automation" in intelligent production; the dual operating condition adaptation mode can be extended to the production of multiple categories such as medium-length tobacco, comprehensively improving the level of intelligent flexible production of the tobacco processing line, and has good industry promotion value.

[0062] The technical solution provided by this invention involves: acquiring tobacco production plan information; determining the tobacco production grade information corresponding to each target batch of tobacco from the production plan information; determining the target tobacco type based on the tobacco production grade information and a preset tobacco type relationship; determining the working frequency of the dust collector fan and the circulating fan based on the target tobacco type and a preset frequency mapping relationship; and controlling the frequency converter of the target air separator based on the air separator's working frequency. This invention solves the problem of unstable air separator quality caused by manual adjustment delays and parameter rigidity in existing tobacco processing technologies. It can determine the tobacco type corresponding to each batch of tobacco based on the production plan information and automatically match and determine the corresponding air separator's working frequency based on the tobacco type, thereby improving the efficiency and batch stability of tobacco air separators.
