Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of cigarette production, and particularly relate to a parameter adjustment method and device of a filter rod forming machine and a storage medium. BACKGROUND

[0002] Draw resistance is one of the core quality indicators of filter rods, and is directly related to the smoking comfort of cigarettes, the filtering efficiency of harmful components such as smoke release and tar.

[0003] In the prior art, the process parameters of the filter rod forming machine are mainly adjusted by mechanical means relying on human experience, that is, the comprehensive test table samples and detects the filter rods at the outlet of the filter rod forming machine product, detects the draw resistance data of the filter rods, and displays the draw resistance data on the display of the upper computer. Then, the operator observes the size relationship between the draw resistance data and the draw resistance standard value through the display, and manually adjusts the process parameters of the filter rod forming machine, such as the opening roller speed ratio parameter.

[0004] However, the above adjustment method relying on human experience has the following disadvantages: first, it is lagging, that is, the manual adjustment method has a low speed and cannot quickly respond to product abnormalities; second, it is multiple, that is, the operator often needs to adjust the parameters multiple times to ensure the stability of the draw resistance data of the filter rods; third, it is subjective, that is, different operators have different adjustment degrees of the process parameters of the filter rod forming machine; and fourth, it is continuous, that is, the operator needs to pay attention to the change of the draw resistance data throughout the production process, which increases the working intensity of the operator, wastes human resources, and thus reduces the parameter adjustment efficiency and accuracy of the filter rod forming machine and reduces the production qualification rate of the filter rods.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, any other embodiments obtained by a person of ordinary skill in the art without creative effort should fall within the protection scope of the present application.

[0018] It should be noted that the terms "first", "second", "target", "original" and the like in the description, claims, and drawings of the present application are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0019] Figure 1 is a flowchart of a parameter adjustment method of a filter rod forming machine provided by the embodiments of the present application. The embodiments can be applied to a scenario in which the parameters of the filter rod forming machine need to be adjusted according to the draw resistance detection value of the filter rod. The parameter adjustment method of the filter rod forming machine provided by the embodiments can be executed by the parameter adjustment device of the filter rod forming machine provided by the embodiments, which can be realized by software and / or hardware. In a specific embodiment, the parameter adjustment device of the filter rod forming machine can be integrated in an electronic device, which is an industrial computer of the filter rod forming machine and is used to control the filter rod forming machine. For example, the electronic device can be a computer or the like. The execution subject of the method can be an electronic device. Referring to Figure 1 , the parameter adjustment method of the filter rod forming machine of the embodiments includes but is not limited to the following steps:

[0020] S110, in response to satisfying a preset parameter adjustment trigger condition, determining a mean value of at least two historical draw resistance detection values and a newly written current draw resistance detection value in the draw resistance data storage structure, to obtain a target draw resistance mean value.

[0021] The preset parameter adjustment trigger condition is a trigger condition of a preset parameter adjustment mechanism. Optionally, the preset parameter adjustment trigger condition includes that the draw resistance data storage structure is full.

[0022] The resistance data storage structure is used to store effective resistance detection values, and provides data basis for subsequent parameter adjustment. For example, the resistance data storage structure can be a ring queue. The resistance detection value is the resistance data obtained by sampling and detecting the filter rod at the product outlet of the filter rod forming machine by the comprehensive test platform. One resistance detection value corresponds to one detection time. It should be noted that the resistance detection value detected earlier is written into the resistance data storage structure first, so that the plurality of resistance detection values stored in the resistance data storage structure are arranged in chronological order of detection time. The resistance detection value detected earlier is located at the front of the resistance data storage structure, and the resistance detection value detected later is located at the rear of the resistance data storage structure.

[0023] The historical resistance detection value is not the latest resistance detection value among the plurality of resistance detection values stored in the resistance data storage structure. The current resistance detection value is the latest resistance detection value among the plurality of resistance detection values stored in the resistance data storage structure. The target resistance average value is the average value of the plurality of resistance detection values stored in the resistance data storage structure. For example, it is known that the capacity of the resistance data storage structure is 4, and the resistance detection values stored in the resistance data storage structure are resistance detection value 1, resistance detection value 2, resistance detection value 3 and resistance detection value 4 in chronological order of detection time from front to back. At this time, the historical resistance detection value includes resistance detection value 1, resistance detection value 2 and resistance detection value 3, and the current resistance detection value is resistance detection value 4.

[0024] Specifically, the comprehensive test platform extracts the filter rod at the product outlet of the filter rod forming machine according to a preset time interval, detects the resistance of the extracted filter rod, obtains the resistance detection value, then saves the resistance detection value to the database, and simultaneously feeds back the resistance detection value to the electronic device. Thus, the electronic device can obtain the resistance detection value obtained by sampling and detecting the filter rod at the product outlet of the filter rod forming machine by the comprehensive test platform, write the resistance detection value into the resistance data storage structure, then determine whether the resistance data storage structure is full, and determine that the preset parameter adjustment trigger condition is met when it is determined that the resistance data storage structure is full.

[0025] In response to the fact that the preset parameter adjustment trigger condition is met, the resistance detection value that is not the latest resistance detection value among the plurality of resistance detection values stored in the resistance data storage structure is determined as the historical resistance detection value. At this time, there are at least two historical resistance detection values, and the latest resistance detection value among the plurality of resistance detection values stored in the resistance data storage structure is determined as the current resistance detection value. Then, the average value of the at least two historical resistance detection values and the current resistance detection value is calculated to obtain the target resistance average value. It should be noted that the meaning of “at least two historical resistance detection values” in the embodiment of the application is all historical resistance detection values stored in the resistance data storage structure.

[0026] Optionally, the suction resistance detection values obtained by the sampling detection of the comprehensive test bench can be grouped, and the suction resistance detection values of a set, such as 10 or 30 filter rods, are set as a group, and the suction resistance standard deviation of a group of suction resistance detection values obtained by the sampling detection of the comprehensive test bench is calculated; when the suction resistance standard deviation is too large, the filter rods produced by the filter rod making machine do not meet the production requirements (i.e., do not meet the suction resistance requirements), and when the capacity of the suction resistance data storage structure is too large, the parameter adjustment frequency of the filter rod making machine is reduced, and the suction resistance standard deviation is also large; when the capacity of the suction resistance data storage structure is too small, the parameter adjustment frequency of the filter rod making machine is increased, and there is excessive adjustment, and the suction resistance standard deviation is also large, so after the capacity of the suction resistance data storage structure is set according to the actual business requirements, the capacity of the suction resistance data storage structure can be fine-tuned according to the running situation of the filter rod making machine and the suction resistance standard deviation of a group of suction resistance detection values obtained by the sampling detection of the comprehensive test bench; for example, the capacity of the suction resistance data storage structure is 4 or 5.

[0027] In S120, a current state of the target suction resistance average value is determined based on a size relationship between the target suction resistance average value, a preset suction resistance standard value, and a preset suction resistance change threshold value.

[0028] The preset suction resistance standard value and the preset suction resistance change threshold value are preset values for determining the state of the suction resistance average value and whether the suction resistance detection value meets the suction resistance requirement; optionally, the preset suction resistance change threshold value can be determined as a difference between a preset suction resistance upper limit value and the preset suction resistance standard value, wherein the preset suction resistance upper limit value is a preset value.

[0029] The current state is a state in which the target suction resistance average value is located, and is used to determine whether the current production situation of the filter rod making machine meets the suction resistance requirement. Optionally, the state of the suction resistance average value can be divided into four states, i.e., a first state, a second state, a third state, and a fourth state.

[0030] Specifically, the current state of the target suction resistance average value can be determined based on a size relationship between the target suction resistance average value, the preset suction resistance standard value, and the preset suction resistance change threshold value, i.e., a difference between the target suction resistance average value and the preset suction resistance standard value can be calculated to obtain an average change value, and the current state of the target suction resistance average value is determined based on a size relationship between the average change value and the preset suction resistance change threshold value, for example, the average change value and the preset suction resistance change threshold value can be used to query a preset mapping relationship to obtain a corresponding average state, and the average state is determined as the current state of the target suction resistance average value, wherein the preset mapping relationship is a preset mapping relationship including a corresponding relationship between the average change value, the preset suction resistance change threshold value, and the average state.

[0031] S130, determining a target parameter adjustment strategy based on the current state of the target average draw resistance and a size relationship between the current draw resistance detection value, the preset draw resistance standard value, and the preset draw resistance change threshold.

[0032] The target parameter adjustment strategy is a strategy for adjusting the process parameters of the filter rod forming machine, and the target parameter adjustment strategy includes a target parameter adjustment value of the process parameters, and the target parameter adjustment value is an adjustment value required by the process parameters at the current time.

[0033] Optionally, the process parameter of the filter rod forming machine that needs to be adjusted can be an opening roller speed ratio parameter; the opening roller speed ratio parameter includes a first opening roller speed ratio parameter V1 / VKDF, a second opening roller speed ratio parameter V2 / VKDF, and a third opening roller speed ratio parameter V3 / VKDF, wherein V1 represents a feeding roller speed of the filter rod forming machine, V2 represents an extension roller speed of the filter rod forming machine, V3 represents a supply roller speed of the filter rod forming machine, and VKDF represents a filter rod speed of the filter rod forming machine.

[0034] Specifically, the target parameter adjustment strategy can be determined based on the current state of the target average draw resistance and a size relationship between the current draw resistance detection value, the preset draw resistance standard value, and the preset draw resistance change threshold, that is, a difference between the current draw resistance detection value and the preset draw resistance standard value can be calculated to obtain a current draw resistance change value, and the target parameter adjustment strategy can be determined based on the current state of the target average draw resistance and a size relationship between the current draw resistance change value and the preset draw resistance change threshold, for example, the current state of the target average draw resistance, the current draw resistance change value, and the preset draw resistance change threshold are input into a pre-trained adjustment strategy determination model, at this time, the adjustment strategy determination model analyzes the size relationship between the current state of the target average draw resistance and the current draw resistance change value and the preset draw resistance change threshold by using the learned model parameters, and outputs the target parameter adjustment strategy. The adjustment strategy determination model is a pre-trained deep learning model, which is used to determine the parameter adjustment strategy of the filter rod forming machine based on the mean state of the draw resistance mean value and the current draw resistance change value.

[0035] S140, adjusting the opening roller speed ratio parameter of the filter rod forming machine according to the target parameter adjustment strategy.

[0036] Specifically, the target parameter adjustment value of each opening roller speed ratio parameter can be parsed from the target parameter adjustment strategy, and the corresponding opening roller speed ratio parameter can be adjusted according to the target parameter adjustment value, so that the filter rod produced by the filter rod forming machine meets the draw resistance requirement.

[0037] The technical scheme of the embodiment of the present application is in response to the satisfaction of the preset parameter adjustment trigger condition, determines the mean value of at least two historical draw resistance detection values in the draw resistance data storage structure and the newly written current draw resistance detection value to obtain a target draw resistance mean value, then determines the current state of the target draw resistance mean value based on the size relationship between the target draw resistance mean value, the preset draw resistance standard value and the preset draw resistance change threshold, and then determines the target parameter adjustment strategy based on the current state of the target draw resistance mean value and the size relationship between the current draw resistance detection value, the preset draw resistance standard value and the preset draw resistance change threshold. After that, the opening roller speed ratio parameter of the plug rod forming machine is adjusted according to the target parameter adjustment strategy, which can realize the full-automatic plug rod draw resistance detection feedback and the self-adjustment function of the plug rod forming machine process parameter without manual supervision, that is, the closed-loop feedback self-adaptive intelligent fine-tuning control function of the plug rod forming machine draw resistance index is realized, manual inspection is not required, the labor cost is reduced, the automation and intelligentization of the plug rod production process are further realized, and the problems of the lag, multiple, subjectivity and continuity of the manual adjustment mode are solved, the parameter adjustment efficiency and parameter adjustment accuracy of the plug rod forming machine are improved, and the intelligent real-time control level of the plug rod forming machine in producing plug rods is improved, thereby effectively improving the stability and consistency of the plug rod draw resistance, reducing the quality fluctuation and raw material loss of the plug rod, improving the production qualified rate of the plug rod, further realizing the leap-forward improvement of the product quality, and effectively promoting the progress of the cigarette production industry technology.

[0038] The parameter adjustment method of the plug rod forming machine provided by the embodiment of the present application is further described below, Figure 2 is another flowchart of the parameter adjustment method of the plug rod forming machine provided by the embodiment of the present application. The embodiment of the present application is a detailed description of determining whether the preset parameter adjustment trigger condition is met before responding to the satisfaction of the preset parameter adjustment trigger condition. Referring to Figure 2 , the method of the embodiment includes but is not limited to the following steps:

[0039] S210, obtaining a first draw resistance detection value obtained by a comprehensive test bench detecting a plug rod to be detected produced by a plug rod forming machine.

[0040] Among them, the plug rod to be detected is a plug rod sampled by the comprehensive test bench from the finished product outlet of the plug rod forming machine at the current time; the first draw resistance detection value is the draw resistance detection value obtained by the comprehensive test bench detecting the plug rod to be detected.

[0041] S220, determining whether the first draw resistance detection value is valid data based on the size relationship between the first draw resistance detection value, the preset draw resistance standard value and the preset draw resistance change threshold.

[0042] Specifically, in one implementation, an absolute value of a difference between the first suction resistance detection value and the preset suction resistance standard value can be calculated to obtain a first deviation value, and the first deviation value at this time is an absolute value; then, when the first deviation value is less than a product of the preset suction resistance change threshold and a first coefficient, it is determined that the first suction resistance detection value is valid data, and S230 is executed; otherwise, it is indicated that the first suction resistance detection value is abnormal, it is determined that the first suction resistance detection value is invalid data, and S240 is executed. The first coefficient is set in advance according to actual business requirements, and in the embodiments of the present application, the first coefficient is obtained according to a large number of experiments. For example, the first coefficient can be 2.

[0043] In another implementation, an absolute value of a difference between the first suction resistance detection value and the preset suction resistance standard value is calculated to obtain a first deviation value; then, when the first deviation value is less than a product of the preset suction resistance change threshold and a first coefficient, it is indicated that the first suction resistance detection value can not be abnormal, at this time, a mean value of the first suction resistance detection value and suction resistance detection values already stored in the suction resistance data storage structure is calculated to obtain a first suction resistance mean value, and an absolute value of a difference between the first suction resistance mean value and the preset suction resistance standard value is calculated to obtain a second deviation value, and the second deviation value at this time is an absolute value; then, when the first deviation value and the second deviation value satisfy a preset valid condition, it is indicated that the first suction resistance detection value is not abnormal, at this time, it is determined that the first suction resistance detection value is valid data, and S230 is executed; wherein, the preset valid condition includes that the second deviation value is less than a product of the preset suction resistance change threshold and a second coefficient, or the second deviation value is not less than the product of the preset suction resistance change threshold and the second coefficient and the first deviation value is less than the preset suction resistance change threshold; the second coefficient is set in advance according to actual business requirements, and in the embodiments of the present application, the second coefficient is obtained according to a large number of experiments, and the second coefficient is less than the first coefficient. For example, the second coefficient can be 1 / 2.

[0044] When the first deviation value and the second deviation value do not satisfy the preset valid condition, that is, the second deviation value is not less than the product of the preset suction resistance change threshold and the second coefficient, and the first deviation value is not less than the preset suction resistance change threshold, it is indicated that the first suction resistance detection value is abnormal, at this time, it is determined that the first suction resistance detection value is invalid data, and S240 is executed.

[0045] When the first deviation value is not less than the product of the preset suction resistance change threshold and the first coefficient, it is indicated that the first suction resistance detection value is abnormal, at this time, it is determined that the first suction resistance detection value is invalid data, and S240 is executed.

[0046] In the embodiment of the present application, the size relationship between the first suction resistance detection value, the preset suction resistance standard value and the preset suction resistance change threshold value, and the size relationship between the first suction resistance average value, the preset suction resistance standard value and the preset suction resistance change threshold value can be used to accurately determine whether the first suction resistance detection value is valid data, and can improve the calculation efficiency and reduce the implementation complexity, thereby providing accurate data for subsequent suction resistance data storage structure.

[0047] S230, when the first suction resistance detection value is valid data, writing the first suction resistance detection value into the suction resistance data storage structure, and when the number of suction resistance detection values in the suction resistance data storage structure is greater than the preset number threshold, determining that the preset parameter adjustment trigger condition is met.

[0048] The preset number threshold is a preset value, which is used to represent the capacity of the suction resistance data storage structure.

[0049] Specifically, when the first suction resistance detection value is valid data, the first suction resistance detection value can be written into the suction resistance data storage structure, and then it is determined whether the number of suction resistance detection values stored in the suction resistance data storage structure is greater than the preset number threshold. If the number of suction resistance detection values stored in the suction resistance data storage structure is greater than the preset number threshold, it indicates that the suction resistance data storage structure is full, and at this time it is determined that the preset parameter adjustment trigger condition is met. Otherwise, it indicates that the suction resistance data storage structure is not full, and at this time S210 is continued to be executed to obtain a new suction resistance detection value from the comprehensive test bench.

[0050] S240, when the first suction resistance detection value is invalid data, rejecting the first suction resistance detection value and determining a rejection count value.

[0051] The rejection count value is the number of times that the suction resistance detection value obtained from the comprehensive test bench is invalid data in the process of filling the suction resistance data storage structure.

[0052] Specifically, when the first suction resistance detection value is invalid data, the first suction resistance detection value can be rejected, that is, the first suction resistance detection value is not written into the suction resistance data storage structure, and then it is detected whether there is a rejection count value. If there is a rejection count value, the rejection count value is updated, that is, the rejection count value is increased by 1. Otherwise, it is determined that the rejection count value is 1.

[0053] S250, determining whether the rejection count value is greater than a preset design count threshold.

[0054] The preset design count threshold is a preset value, which is used to represent a critical value that needs to exclude system parameter errors. The system parameter error here refers to the parameter setting error of the electronic device, and the parameters of the electronic device include the preset suction resistance standard value, the preset suction resistance upper limit value and the preset suction resistance change threshold value.

[0055] Specifically, if the culling count value is greater than the preset count threshold value, it is necessary to exclude system parameter errors, at this time S260 can be executed; otherwise, it indicates that there is no need to exclude system parameter errors, at this time S210 can be executed to continue to obtain a new suction resistance detection value from the comprehensive test bench.

[0056] S260, when the culling count value is greater than the preset count threshold value, generating an alarm information and displaying the alarm information to prompt the operator to check whether there is a system parameter error.

[0057] Specifically, when the culling count value is greater than the preset count threshold value, an alarm information can be generated and displayed to prompt the operator to check whether there is a system parameter error; then, the operator can check the preset suction resistance standard value, the preset suction resistance upper limit value and the preset suction resistance change threshold value to check whether there is a system parameter error, if there is a system parameter error, the preset suction resistance standard value, the preset suction resistance upper limit value and the preset suction resistance change threshold value are adjusted, and after the adjustment, the "get suction resistance detection value" control in the display screen interface of the electronic device is clicked; otherwise, the "get suction resistance detection value" control in the display screen interface of the electronic device is directly clicked.

[0058] S270, detecting the data collection recovery operation of the operator to determine that the data collection recovery condition is met.

[0059] The data collection recovery operation is the operation of the operator clicking the "get suction resistance detection value" control in the display screen interface of the electronic device; the data collection recovery condition is the trigger condition for recovering to obtain a new suction resistance detection value from the comprehensive test bench.

[0060] Specifically, when the electronic device detects the clicking operation of the operator on the "get suction resistance detection value" control, it is determined that the data collection recovery operation of the operator is detected, at this time it can be determined that the data collection recovery condition is met, and then S210 is executed to continue to obtain a new suction resistance detection value from the comprehensive test bench.

[0061] The technical scheme of the embodiment of the application can obtain a first suction resistance detection value of a filter rod to be detected produced by a filter rod making machine detected by a comprehensive test bench, and determine whether the first suction resistance detection value is valid data based on the size relationship between the first suction resistance detection value, the preset suction resistance standard value and the preset suction resistance change threshold value; when the first suction resistance detection value is valid data, the first suction resistance detection value is written into the suction resistance data storage structure, that is, all the suction resistance detection values stored in the suction resistance data storage structure are valid data, which can provide accurate data basis for abnormal judgment of suction resistance detection value and subsequent parameter adjustment, and then when the number of suction resistance detection values in the suction resistance data storage structure is greater than the preset number threshold value, it is determined that the preset parameter adjustment trigger condition is met, which can provide accurate trigger time for subsequent parameter adjustment mechanism, thereby improving the parameter adjustment accuracy of the filter rod making machine.

[0062] When the first draw resistance detection value is invalid data, the first draw resistance detection value is rejected, the abnormal draw resistance detection value can be deleted, the abnormal draw resistance detection value processing function is realized, then the rejection count value is determined, and when the rejection count value is greater than the preset count threshold value, alarm information is generated and displayed to prompt the operator to check whether there is a system parameter error, and after detecting the data collection operation of the operator, it is determined that the data collection recovery condition is met, which can exclude system parameter errors when the draw resistance detection value is abnormal, effectively avoiding the situation that the draw resistance detection value is abnormal due to system parameter errors, thereby improving the efficiency of obtaining effective draw resistance detection values, thereby improving the parameter adjustment efficiency of the filter rod making machine.

[0063] The parameter adjustment method of the filter rod making machine provided by the embodiment of the application is further described below, Figure 3 is another flowchart of the parameter adjustment method of the filter rod making machine provided by the embodiment of the application. The embodiment of the application is optimized on the basis of the above-mentioned embodiments. Referring to Figure 3 , the method of the embodiment includes but is not limited to the following steps:

[0064] S301, in response to the fact that the preset parameter adjustment trigger condition is met, the mean value of at least two historical draw resistance detection values and the newly written current draw resistance detection value in the draw resistance data storage structure is determined to obtain a target draw resistance mean value.

[0065] S302, the difference between the target draw resistance mean value and the preset draw resistance standard value is calculated to obtain a mean value change value.

[0066] Then, according to the condition met by the mean value change value, S303, S306, S308 or S310 is executed.

[0067] S303, when the mean value change value is greater than the product of the preset draw resistance change threshold value and a third coefficient, it is determined that the current state of the target draw resistance mean value is the first state.

[0068] The third coefficient is set in advance according to actual business requirements, and in the embodiment of the application, it is obtained according to a large number of experiments. For example, the third coefficient can be 1 / 10.

[0069] S304, the difference between adjacent historical draw resistance detection values in the at least two historical draw resistance detection values is calculated in the order from the back to the front of the detection time to obtain a historical draw resistance difference value.

[0070] The historical draw resistance difference value is the difference between adjacent historical draw resistance detection values, and is the difference between the historical draw resistance detection value with the later detection time and the adjacent historical draw resistance detection value with the earlier detection time, which is used to simulate the nearest future state according to the nearest past state.

[0071] For example, if it is known that the at least two historical draw resistance detection values are historical draw resistance detection value 1, historical draw resistance detection value 2 and historical draw resistance detection value 3 in the order of detection time from early to late, then the historical draw resistance difference value 1 (i.e., △pd1) is the difference between the historical draw resistance detection value 3 and the historical draw resistance detection value 2, and the historical draw resistance difference value 2 (i.e., △pd2) is the difference between the historical draw resistance detection value 2 and the historical draw resistance detection value 1.

[0072] S305, when the historical draw resistance difference value and the current draw resistance detection value satisfy the first set adjustment condition, determining that the target parameter adjustment strategy is to correct the mean value change value by using the first set correction value to obtain a first draw resistance change value, and reducing the opening roller speed ratio parameter based on the first draw resistance change value and a relationship function between the pre-determined draw resistance change value and the parameter adjustment value of the opening roller speed ratio parameter.

[0073] The first set adjustment condition includes at least one of a first condition that the historical draw resistance difference value is greater than the product of the pre-set draw resistance change threshold and a third coefficient, and a second condition that the difference between the current draw resistance detection value and the pre-set draw resistance standard value is greater than the product of the pre-set draw resistance change threshold and a fifth coefficient.

[0074] The fifth coefficient is set in advance according to actual business needs, and in the embodiments of the present application, it is obtained through a large number of experiments. For example, the fifth coefficient is 1 / 5. The first set correction value is set in advance according to actual business needs, and in the embodiments of the present application, it is obtained through a large number of experiments, and is used to prevent parameter over-adjustment. In addition, the first set correction value is less than 0, and for example, the first set correction value is -10.

[0075] Optionally, if there are at least two historical draw resistance difference values, the first set adjustment condition includes at least one of the first condition, the second condition and a third condition. The first condition is that all the historical draw resistance difference values are greater than the product of the pre-set draw resistance change threshold and the third coefficient. The third condition is that the historical draw resistance difference value with the latest detection time is greater than the product of the pre-set draw resistance change threshold and the third coefficient, and the difference between the absolute value of the historical draw resistance difference value with the latest detection time and the absolute value of the adjacent historical draw resistance difference value with the early detection time is greater than the product of the pre-set draw resistance change threshold and the third coefficient. For example, continuing the example of S304, the detection time of △pd1 is later than that of △pd2, and the detection times of △pd1 and △pd2 are adjacent, then the third condition is that △pd1 is greater than the product of the pre-set draw resistance change threshold and the third coefficient, and |△pd1|-|△pd2| is greater than the product of the pre-set draw resistance change threshold and the third coefficient.

[0076] It should be noted that the first condition is used to represent that the suction resistance detection value is continuously increasing and the increasing amplitude is large from the historical suction resistance detection value; the second condition is used to represent that the current suction resistance detection value has undergone a sharp change compared with the preset suction resistance standard value; and the third condition is used to represent that the historical suction resistance detection value has undergone a shock, and the amplitude of the last time is greater than that of the last time.

[0077] Specifically, when the current state of the target suction resistance average value is the first state, and the historical suction resistance difference value and the current suction resistance detection value satisfy the first set adjustment condition, it indicates that the current production situation of the plug wrap making machine does not meet the suction resistance requirement, and the opening roller speed ratio parameter of the plug wrap making machine needs to be adjusted. At this time, the sum of the average change value and the first set correction value is calculated to obtain a first suction resistance change value. Then, a relationship function between the predetermined suction resistance change value and the parameter adjustment value of the first opening roller speed ratio parameter is obtained, denoted as a first relationship function, and the first suction resistance change value is substituted into the first relationship function to obtain a first candidate parameter adjustment value of the first opening roller speed ratio parameter. Then, in order to prevent the mutation of the opening roller speed ratio parameter and damage the smoothness of the plug wrap production, an amplitude limiting protection can be added, that is, the absolute value of the target parameter adjustment value of the first opening roller speed ratio parameter cannot exceed the preset adjustment value. Therefore, the target parameter adjustment value of the first opening roller speed ratio parameter is ΔV1 / VKDF=-min(a×△p1,L), wherein △p1 is the first suction resistance change value; a×△p1 is the first candidate parameter adjustment value; a is a coefficient in the first relationship function, for example, a is 0.01; L is the preset adjustment value; and the ΔV1 / VKDF at this time is less than zero.

[0078] The preset adjustment value is set in advance according to actual business requirements, and in the embodiment of the present application, it is obtained according to a large number of experiments. For example, the preset adjustment value is 0.1. The relationship function between the suction resistance change value and the parameter adjustment value of the first opening roller speed ratio parameter is a statistical relationship obtained by linear regression on historical data. The historical data includes a plurality of historical suction resistance change values of the plug wrap making machine and a historical parameter adjustment value of the first opening roller speed ratio parameter corresponding to each historical suction resistance change value.

[0079] After obtaining the target parameter adjustment value of the first opening roller speed ratio parameter, a predetermined relationship function between the parameter adjustment value of the first opening roller speed ratio parameter and the parameter adjustment value of the second opening roller speed ratio parameter is obtained, denoted as a second relationship function, and the target parameter adjustment value of the first opening roller speed ratio parameter is substituted into the second relationship function to obtain the target parameter adjustment value of the second opening roller speed ratio parameter. Then, a predetermined relationship function between the parameter adjustment value of the first opening roller speed ratio parameter and the parameter adjustment value of the third opening roller speed ratio parameter is obtained, denoted as a third relationship function, and the target parameter adjustment value of the first opening roller speed ratio parameter is substituted into the third relationship function to obtain the target parameter adjustment value of the third opening roller speed ratio parameter. Then, S313 is executed.

[0080] The relationship function between the parameter adjustment value of the first opening roller speed ratio parameter and the parameter adjustment value of the second opening roller speed ratio parameter is a statistical relationship obtained by linear regression on historical data, and the historical data includes a plurality of historical parameter adjustment values of the first opening roller speed ratio parameter and corresponding historical parameter adjustment values of the second opening roller speed ratio parameter of the plug wrap forming machine. For example, the second relationship function is ΔV2 / VKDF=b×ΔV1 / VKDF, and b is 1.026. The relationship function between the parameter adjustment value of the first opening roller speed ratio parameter and the parameter adjustment value of the third opening roller speed ratio parameter is a statistical relationship obtained by linear regression on historical data, and the historical data includes a plurality of historical parameter adjustment values of the first opening roller speed ratio parameter and corresponding historical parameter adjustment values of the third opening roller speed ratio parameter of the plug wrap forming machine. For example, the third relationship function is ΔV3 / VKDF=c×ΔV1 / VKDF, and c is 0.89.

[0081] Optionally, when the current state of the target average draw resistance is the first state, and the historical draw resistance difference value and the current draw resistance detection value do not satisfy the first set adjustment condition, it indicates that the current production situation of the plug wrap forming machine meets the draw resistance requirement, and the opening roller speed ratio parameter of the plug wrap forming machine does not need to be adjusted.

[0082] S306, when the average change value is greater than zero and not greater than the product of the preset draw resistance change threshold and the third coefficient, it is determined that the current state of the target average draw resistance is the second state.

[0083] S307, when the difference between the current draw resistance detection value and the preset draw resistance standard value is greater than the product of the preset draw resistance change threshold and the fifth coefficient, it is determined that the target parameter adjustment strategy is to reduce the opening roller speed ratio parameter based on the first set adjustment value.

[0084] The first set adjustment value is a parameter adjustment value of a first opening roller speed ratio parameter of a minimum unit, which is set in advance according to actual business requirements, and is less than zero in the embodiment of the application. For example, the first set adjustment value is -0.001.

[0085] Specifically, in the case where the current state of the target average draw resistance is the second state, the case where the current draw resistance detection value suddenly changes is excluded, the difference between the current draw resistance detection value and the preset draw resistance standard value is calculated to obtain a current draw resistance change value, and then, based on the size relationship between the current draw resistance change value and the preset draw resistance change threshold, it is determined whether the current production situation of the plug rod making machine meets the draw resistance requirement. If the current draw resistance change value is greater than the product of the preset draw resistance change threshold and the fifth coefficient, it indicates that the current production situation of the plug rod making machine does not meet the draw resistance requirement, and the opening roller speed ratio parameter of the plug rod making machine needs to be adjusted. At this time, the first set adjustment value is determined as the target parameter adjustment value of the first opening roller speed ratio parameter, and at this time, ΔV1 / VKDF is less than zero. Then, the target parameter adjustment value of the second opening roller speed ratio parameter is determined by using the second relationship function and the target parameter adjustment value of the first opening roller speed ratio parameter, and the target parameter adjustment value of the third opening roller speed ratio parameter is determined by using the third relationship function and the target parameter adjustment value of the first opening roller speed ratio parameter. Then, S313 is executed.

[0086] If the current state of the target average draw resistance is the second state, and the current draw resistance change value is not greater than the product of the preset draw resistance change threshold and the fifth coefficient, it indicates that the current production situation of the plug rod making machine meets the draw resistance requirement, and the opening roller speed ratio parameter of the plug rod making machine does not need to be adjusted.

[0087] S308, when the average change value is greater than the product of the preset draw resistance change threshold and the fourth coefficient and is not greater than zero, it is determined that the current state of the target average draw resistance is the third state.

[0088] The fourth coefficient is set in advance according to actual business requirements, and is obtained according to a large number of experiments in the embodiment of the application. The third coefficient and the fourth coefficient are opposite numbers, for example, the fourth coefficient can be -1 / 10.

[0089] S309, when the difference between the current draw resistance detection value and the preset draw resistance standard value is less than the product of the preset draw resistance change threshold and the sixth coefficient, it is determined that the target parameter adjustment strategy is to increase the opening roller speed ratio parameter based on the second set adjustment value.

[0090] The sixth coefficient is set in advance according to actual business requirements, and is obtained according to a large number of experiments in the embodiment of the application. The sixth coefficient and the fifth coefficient are opposite numbers, for example, the sixth coefficient is -1 / 5.

[0091] The second set adjustment value is a parameter adjustment value of a first opening roller speed ratio parameter in a minimum unit, which is set in advance according to actual business requirements, and in the embodiment of the present application, the second set adjustment value is obtained according to a large number of experiments, and the first set adjustment value and the second set adjustment value are reciprocals of each other; for example, the second set adjustment value is 0.001.

[0092] Specifically, in the case that the current state of the target average draw resistance is the third state, it is necessary to exclude the case that the current draw resistance detection value suddenly changes, to calculate a difference between the current draw resistance detection value and the preset draw resistance standard value, to obtain a current draw resistance change value, and then to determine whether the current production situation of the plug wrap forming machine meets the draw resistance requirement based on a size relationship between the current draw resistance change value and the preset draw resistance change threshold value. If the current draw resistance change value is less than a product of the preset draw resistance change threshold value and the sixth coefficient, it indicates that the current production situation of the plug wrap forming machine does not meet the draw resistance requirement, and it is necessary to adjust the opening roller speed ratio parameter of the plug wrap forming machine. At this time, the second set adjustment value is determined as the target parameter adjustment value of the first opening roller speed ratio parameter, and △V1 / VKDF at this time is greater than zero. Then, the target parameter adjustment value of the second opening roller speed ratio parameter is determined by using the second relationship function and the target parameter adjustment value of the first opening roller speed ratio parameter, and the target parameter adjustment value of the third opening roller speed ratio parameter is determined by using the third relationship function and the target parameter adjustment value of the first opening roller speed ratio parameter. After that, S313 is executed.

[0093] If the current state of the target average draw resistance is the third state, and the current draw resistance change value is not less than the product of the preset draw resistance change threshold value and the sixth coefficient, it indicates that the current production situation of the plug wrap forming machine meets the draw resistance requirement, and it is not necessary to adjust the opening roller speed ratio parameter of the plug wrap forming machine.

[0094] S310, when the average change value is not greater than the product of the preset draw resistance change threshold value and the fourth coefficient, the current state of the target average draw resistance is determined as the fourth state.

[0095] S311, the difference between adjacent historical draw resistance detection values in at least two historical draw resistance detection values is calculated in the order from the back to the front of the detection time, to obtain a historical draw resistance difference value.

[0096] S312, when the historical draw resistance difference value and the current draw resistance detection value meet the second set adjustment condition, the target parameter adjustment strategy is determined as that the second set correction value is used to correct the average change value to obtain a second draw resistance change value, and the opening roller speed ratio parameter is adjusted to increase based on the second draw resistance change value and a relationship function between the preset draw resistance change value and the parameter adjustment value of the opening roller speed ratio parameter.

[0097] The second set correction value is set in advance according to actual business requirements, and is obtained according to a large number of experiments in the embodiment of the present application, is used to prevent parameter over-adjustment, and the second set correction value and the first set correction value are reciprocals of each other. For example, the second set correction value is 10.

[0098] The second set adjustment condition includes at least one of a fourth condition that the historical draw resistance difference values are all less than a product of the preset draw resistance change threshold and a fourth coefficient, and a fifth condition that a difference between the current draw resistance detection value and the preset draw resistance standard value is less than a product of the preset draw resistance change threshold and a sixth coefficient.

[0099] Optionally, if there are at least two historical draw resistance difference values, the second set adjustment condition includes at least one of the fourth condition, the fifth condition, and a sixth condition. The fourth condition is that all the historical draw resistance difference values are less than the product of the preset draw resistance change threshold and the fourth coefficient. The sixth condition is that the latest historical draw resistance difference value in detection time is less than the product of the preset draw resistance change threshold and the fourth coefficient, and a difference between an absolute value of the latest historical draw resistance difference value in detection time and an absolute value of an adjacent historical draw resistance difference value in detection time is less than the product of the preset draw resistance change threshold and the fourth coefficient. For example, in the example of S304, the detection time of △pd1 is later than that of △pd2, and the detection times of △pd1 and △pd2 are adjacent, the sixth condition is that △pd1 is less than the product of the preset draw resistance change threshold and the fourth coefficient, and |△pd1|-|△pd2| is less than the product of the preset draw resistance change threshold and the fourth coefficient.

[0100] It should be noted that the fourth condition has the same representation meaning as the first condition, the fifth condition has the same representation meaning as the second condition, and the sixth condition has the same representation meaning as the third condition.

[0101] Specifically, in the case that the current state of the target draw resistance average value is the fourth state, when the historical draw resistance difference values and the current draw resistance detection value satisfy the second set adjustment condition, it indicates that the current production situation of the plug rod forming machine does not meet the draw resistance requirement, and the opening roller speed ratio parameter of the plug rod forming machine needs to be adjusted. At this time, the sum of the average change value and the second set correction value is calculated to obtain a second draw resistance change value, and then the second draw resistance change value is substituted into the first relationship function to obtain a second candidate parameter adjustment value of the first opening roller speed ratio parameter. Therefore, the target parameter adjustment value of the first opening roller speed ratio parameter is △V1 / VKDF=-max(a×△p2,-L), where △p2 is the second draw resistance change value, a×△p2 is the second candidate parameter adjustment value, and △V1 / VKDF is greater than zero at this time.

[0102] Then, the target parameter adjustment value of the second opening roller speed ratio parameter is determined by using the second relationship function and the target parameter adjustment value of the first opening roller speed ratio parameter, and the target parameter adjustment value of the third opening roller speed ratio parameter is determined by using the third relationship function and the target parameter adjustment value of the first opening roller speed ratio parameter; then, S313 is executed.

[0103] When the current state of the target average draw resistance value is the fourth state, and the historical draw resistance difference value and the current draw resistance detection value do not satisfy the second set adjustment condition, it indicates that the current production situation of the plug wrap forming machine meets the draw resistance requirement, and the opening roller speed ratio parameter of the plug wrap forming machine does not need to be adjusted.

[0104] S313, adjusting the opening roller speed ratio parameter of the plug wrap forming machine according to the target parameter adjustment strategy.

[0105] It should be noted that S303 to S305, S306 to S307, S308 to S309, S310 to S312 are four parallel branches; according to the size relationship between the average value change value and the preset draw resistance change threshold, the four branches are executed alternatively.

[0106] The technical scheme of the embodiment of the application can accurately determine the current state of the target average draw resistance value, i.e. the first state, the second state, the third state or the fourth state, through the size relationship between the average value change value and the preset draw resistance change threshold; then, by the current state of the target average draw resistance value and the size relationship between the historical draw resistance detection value, the current draw resistance detection value and the preset draw resistance change threshold, different parameter adjustment strategies are adaptively taken, which can improve the calculation efficiency, reduce the implementation complexity, and further improve the determination accuracy and efficiency of the target parameter adjustment strategy; in addition, the full-automatic plug wrap draw resistance detection feedback and the self-adjustment function of the plug wrap forming machine process parameters can be realized, i.e. the closed-loop feedback adaptive intelligent fine-tuning control function of the plug wrap forming machine draw resistance index is realized, manual inspection is not needed, the labor cost is reduced, the automation and intelligence of the plug wrap production process are further realized, the problems of the lag, the plurality, the subjectivity and the continuity of the manual adjustment mode are solved, the parameter adjustment efficiency and the parameter adjustment accuracy of the plug wrap forming machine are improved, and the intelligent real-time control level of the plug wrap forming machine in producing plug wraps is improved, thereby effectively improving the stability and consistency of the plug wrap draw resistance, reducing the quality fluctuation and the raw material loss of the plug wrap, improving the production qualified rate of the plug wrap, further realizing the leap-forward improvement of the product quality, and effectively promoting the progress of the cigarette production industry technology.
