The embodiment of the present invention can be applied to the scenario of performing end analysis on unburned cigarettes. The method can be executed by a cigarette end analysis device, which can be implemented by software and / or hardware.
[0026] like Figure 1 As shown, the cigarette end analysis method comprises the following steps:
[0027] S110 , extracting a preset number of cigarettes to be tested from a target batch of cigarettes, performing an anti-twisting ability test on the cigarettes to be tested, and obtaining a first test result.
[0028] Among them, the target batch of cigarettes may be the target batch of cigarettes that need to be subjected to end-fall analysis. Specifically, the target batch of cigarettes may contain multiple unburned cigarettes. The cigarettes to be tested may be the cigarettes to be subjected to end-fall analysis in the target batch of cigarettes. The method of determining the cigarettes to be tested from the target batch of cigarettes is not limited here. Exemplarily, a preset number of cigarettes may be randomly extracted from the target batch of cigarettes as the cigarettes to be tested, or based on a cigarette extraction instruction issued by a user, the cigarettes corresponding to the cigarette extraction instruction may be used as the cigarettes to be tested.
[0029] Furthermore, the first test result may be a test result of the anti-fracture ability of the cigarette to be tested. The anti-distortion ability test includes but is not limited to the bending ability test, the tensile ability test and the compressive ability test. Specifically, for each cigarette to be tested, the bending ability test, the tensile ability test and the compressive ability test may be performed on the cigarette to be tested to obtain the corresponding bending ability parameters, the tensile ability parameters and the compressive ability parameters, and finally the bending ability parameters, the tensile ability parameters and the compressive ability parameters are statistically summarized to obtain the first test result of the cigarette to be tested.
[0030] S120: Detect the density of the tobacco shreds in the cigarette to be detected to obtain a second detection result.
[0031] The second detection result may be a detection result on the density of tobacco shreds in the cigarette to be detected. Specifically, for each cigarette to be detected, a tomographic scan may be performed on the cigarette to be detected, and the overlap amount and porosity of the tobacco shreds in the cigarette to be detected may be determined based on the scan data, and then the overlap amount and porosity may be statistically summarized to obtain the second detection result of the cigarette to be detected.
[0032] S130: Determine a target cigarette head drop detection result corresponding to the target batch of cigarettes according to the first test result and the second test result.
[0033] The target head drop detection result may be the head drop analysis result of cigarettes in the target batch of cigarettes. Specifically, the first test result and the second test result of each cigarette to be detected may be summarized, and the summarized result may be used as the target head drop detection result corresponding to the target batch of cigarettes.
[0034] The technical solution provided by the embodiment of the present invention extracts a preset number of cigarettes to be tested from a target batch of cigarettes, performs a twisting resistance test on the cigarettes to be tested, and obtains a first test result; tests the density of tobacco shreds in the cigarettes to be tested, and obtains a second test result; and determines the target head drop test result corresponding to the target batch of cigarettes based on the first test result and the second test result. The technical solution of the embodiment of the present invention solves the problem that the cigarette head drop analysis in the prior art needs to be performed in the burning state of the cigarette, which has the problems of cumbersome process, long detection cycle and high destructiveness. It can perform multi-angle detection on unburned cigarettes to determine the target head drop test result, which can reduce the cigarette head drop detection process, reduce the detection time, reduce the use of experimental raw materials, and make it possible to reuse cigarette raw materials.
[0035] Figure 2 It is a flow chart of another cigarette end analysis method provided by an embodiment of the present invention. The embodiment of the present invention can be applied to the scenario of end analysis of unburned cigarettes. Based on the above embodiment, this embodiment further illustrates how to test the anti-twisting ability of the cigarette to be tested to obtain a first test result; and how to test the density of tobacco in the cigarette to be tested to obtain a second test result. The device can be implemented by software and / or hardware and integrated in a computer device with application development function.
[0036] like Figure 2 As shown, the cigarette end analysis method comprises the following steps:
[0037] S210 , extracting a preset number of cigarettes to be tested from a target batch of cigarettes, performing a bending resistance test on the cigarettes to be tested, and obtaining bending resistance parameters corresponding to the cigarettes to be tested.
[0038] Among them, the target batch of cigarettes may be a target batch of cigarettes that need to be subjected to a head drop analysis. Specifically, a plurality of unburned cigarettes may be used in the target batch of cigarettes. The cigarettes to be tested may be cigarettes in the target batch of cigarettes that need to be subjected to a head drop analysis. The method of determining the cigarettes to be tested from the target batch of cigarettes is not limited here. Exemplarily, a preset number of cigarettes may be randomly drawn from the target batch of cigarettes as cigarettes to be tested, or based on a cigarette extraction instruction issued by a user, the cigarettes corresponding to the cigarette extraction instruction may be used as cigarettes to be tested. The bending resistance parameter may be a parameter representing the bending resistance of the cigarette to be tested. Specifically, a bending resistance test may be performed on each cigarette to be tested, and the bending resistance parameter corresponding to each cigarette to be tested may be determined based on the test result.
[0039] Optionally, a bending resistance test is performed on the cigarette to be tested to obtain bending resistance parameters corresponding to the cigarette to be tested, including: when the cigarette to be tested is fixed, a pulling force perpendicular to the axial direction of the cigarette is applied to the top of the cigarette to be tested; when bending and fracture are detected in the cigarette to be tested, the bending force distance and bending force value corresponding to the moment of bending and fracture are used as bending resistance parameters.
[0040] Among them, based on a preset fixing device, the cigarette filter end of the cigarette to be tested can be fixed vertically, and then a uniform pulling force perpendicular to the cigarette axis can be applied to the top of the cigarette. Further, based on a preset detection device, it can be detected whether the cigarette to be tested is broken, and when it is detected that the cigarette to be tested is bent and broken, the bending force distance and bending force value corresponding to the bending and breaking moment are recorded. Among them, the bending force distance can be the torque of the pulling force applied by the cigarette to be tested at the moment of bending and breaking. The bending force value can be the magnitude of the pulling force applied by the cigarette to be tested at the moment of bending and breaking.
[0041] For example, Figure 3 Schematic diagram of a cigarette bending resistance test provided by an embodiment of the present invention. Figure 3 As shown, the filter end of the cigarette can be fixed vertically, and a uniform pulling force perpendicular to the axial direction of the cigarette is applied to the top of the cigarette until the tobacco segment of the cigarette breaks and is damaged, and the bending resistance parameters at the time of breaking are measured.
[0042] S220: Perform a tensile strength test on the cigarette to be tested to obtain a tensile strength parameter corresponding to the cigarette to be tested.
[0043] The tensile strength parameter may be a parameter indicating the tensile strength of the cigarette to be tested. Specifically, a tensile strength test may be performed on each cigarette to be tested, and the tensile strength parameter corresponding to each cigarette to be tested may be determined according to the test result.
[0044] Optionally, a tensile strength test is performed on the cigarette to be tested to obtain tensile strength parameters corresponding to the cigarette to be tested, including: when the cigarette to be tested is fixed, a tensile force is applied to the top of the cigarette to be tested that coincides with the axial direction of the cigarette and is directed outward; when tensile fracture is detected in the cigarette to be tested, the tensile force distance, tensile force value and fracture position corresponding to the moment of tensile fracture are used as tensile strength parameters.
[0045] Among them, based on a preset fixing device, the cigarette filter end of the cigarette to be tested can be fixed vertically, and then a uniform pulling force that coincides with the axial direction of the cigarette and is directed outward can be applied to the top of the cigarette. Furthermore, based on a preset detection device, it can be detected whether the cigarette to be tested is broken, and when it is detected that the cigarette to be tested is tensilely broken, the tensile force distance and tensile force value corresponding to the tensile fracture moment are recorded. Among them, the tensile force distance can be the torque of the tensile force applied by the cigarette to be tested at the moment of tensile fracture. The tensile force value can be the magnitude of the tensile force applied by the cigarette to be tested at the moment of tensile fracture.
[0046] For example, Figure 4 Schematic diagram of a cigarette tensile strength test provided by an embodiment of the present invention. Figure 4 As shown, the filter end of the cigarette is fixed vertically, and a uniform pulling force is applied to the top of the cigarette in an outward direction that coincides with the axial direction of the cigarette until the tobacco segment of the cigarette is stretched and broken, and the tensile strength parameters at the time of fracture are measured.
[0047] S230: Perform a compression resistance test on the cigarette to be tested to obtain a compression resistance parameter corresponding to the cigarette to be tested.
[0048] Among them, the compression resistance parameter may be a parameter indicating the compression resistance of the cigarette to be tested. Specifically, the compression resistance test may be performed on each cigarette to be tested, and the compression resistance parameter corresponding to each cigarette to be tested may be determined based on the test result. Optionally, the compression resistance test is performed on the cigarette to be tested to obtain the compression resistance parameter corresponding to the cigarette to be tested, including: when the cigarette to be tested is fixed, a pulling force is applied to the top of the cigarette to be tested that coincides with the axial direction of the cigarette and is inward; when a crush fracture is detected in the cigarette to be tested, the crush force distance, crush force value and fracture position corresponding to the moment of crush fracture are used as the compression resistance parameter.
[0049] Among them, based on a preset fixing device, the cigarette filter end of the cigarette to be tested can be fixed vertically, and then a uniform pulling force that coincides with the axial direction of the cigarette and is inward is applied to the top of the cigarette. Furthermore, based on a preset detection device, it is possible to detect whether the cigarette to be tested is broken, and in the case of detecting that the cigarette to be tested is crushed and broken, the crushing force distance and the crushing force value corresponding to the moment of the crushing and breaking are recorded. Among them, the crushing force distance can be the torque of the pulling force applied by the cigarette to be tested at the moment of the crushing and breaking. The crushing force value can be the magnitude of the pulling force applied by the cigarette to be tested at the moment of the crushing and breaking.
[0050] For example, Figure 5 Schematic diagram of a cigarette compression resistance test provided by an embodiment of the present invention. Figure 5 As shown, the cigarette filter end can be fixed vertically, and a uniform inward pressure coincident with the axial direction is applied to the other end until the cigarette tobacco segment is crushed and fractured, and the compression resistance parameters at the time of fracture are measured.
[0051] S240: Determine the first test result according to the bending resistance parameter, the tensile resistance parameter and the compressive resistance parameter.
[0052] The first test result may be a test result of the fracture resistance of the cigarette to be tested. Exemplarily, the bending resistance parameters, tensile resistance parameters and compressive resistance parameters of the cigarette to be tested may be summarized, and the summarized parameters may be used as the first test result of the cigarette to be tested. The bending resistance parameters, tensile resistance parameters and compressive resistance parameters of the cigarette to be tested may also be input into a preset fracture resistance analysis model so that the model analyzes various parameters of the cigarette to be tested, thereby obtaining a comprehensive analysis result, and the result output by the model may be used as the first test result.
[0053] For example, it is assumed that the bending, tensile and compressive strength of cigarettes conform to the normal distribution, that is:
[0054]
[0055] Here, x represents the force when the cigarette structure is damaged, μ is the mean value of the force on the cigarette when it is damaged, and σ represents the standard deviation. Data that deviates from 3σ are eliminated. The results of force damage of different types of cigarettes are analyzed. The larger the mean value of the force on the cigarette damage, the more stable the cigarette structure, and the smaller the standard deviation, the smaller the difference in cigarette product quality. For cigarettes with more stable force structures and more stable product quality, their head-falling tendency is smaller.
[0056] S250: Acquire a CT image of the cigarette to be tested, and determine the axial overlap and porosity of the cigarette to be tested according to the CT image.
[0057] Among them, the axial overlap amount can be the amount of mutual overlap between the tobacco shreds inside the cigarette along the axial direction. The porosity can be the ratio of the void space formed between the tobacco shreds inside the cigarette to the internal space of the cigarette. Specifically, a three-dimensional model of the cigarette to be detected can be constructed based on the CT image, and then the three-dimensional model can be analyzed based on the preset analysis algorithm to obtain the axial overlap amount and porosity of the cigarette to be detected. Furthermore, the CT image of each cigarette to be detected can be analyzed to determine the axial overlap amount and porosity corresponding to each cigarette to be detected. Among them, the axial overlap amount between tobacco shreds is considered to be the degree of interaction between tobacco shreds. For the lowest axial overlap amount, it can be considered that the interaction between cigarettes is the weakest, and there may be a higher tendency to fall off. In addition, if the porosity of the cigarette to be detected is high, it means that the filling degree of the tobacco shreds inside the cigarette is uneven, which will also lead to an increase in the probability of falling off.
[0058] For example, Figure 6 Schematic diagram of the overlap between two tobacco shreds provided by an embodiment of the present invention. Figure 6 As shown, x ol is the overlap between two tobacco strands. Figure 7 FIG. 1 is a schematic diagram of the axial porosity of a cigarette provided by an embodiment of the present invention. Figure 7 As shown, a large number of cigarettes in the same batch can be analyzed and counted, and combined with the force and overlap data of the cigarettes, the relationship between the porosity and structural strength of the cigarettes can be constructed, thereby further obtaining the tendency of cigarettes to fall off.
[0059] S260: Determine the second detection result according to the axial overlap and porosity of the plurality of cigarettes to be detected.
[0060] The second test result may be a test result on the density of tobacco shreds of the cigarette to be tested. Exemplarily, the axial overlap and porosity of the cigarette to be tested may be summarized, and the summarized parameters may be used as the second test result of the cigarette to be tested. The axial overlap and porosity of the cigarette to be tested may also be input into a preset tobacco shred analysis model so that the model analyzes various parameters of the cigarette to be tested, thereby obtaining an analysis result of the density of tobacco shreds of the cigarette to be tested, and the result output by the model may be used as the second test result.
[0061] S270: Determine a target cigarette head drop detection result corresponding to the target batch of cigarettes according to the first test result and the second test result.
[0062] The target head drop detection result may be the head drop analysis result of cigarettes in the target batch of cigarettes. Specifically, the first test result and the second test result of each cigarette to be detected may be summarized, and the summarized result may be used as the target head drop detection result corresponding to the target batch of cigarettes.
[0063] Optionally, the anti-twisting ability parameters and density parameters of multiple batches of cigarettes can also be obtained; the anti-twisting ability parameters and density parameters of multiple batches of cigarettes are statistically analyzed to obtain cigarette head drop evaluation results.
[0064] Among them, multiple batches of cigarettes can be selected manually or randomly, which is not limited here. The cigarette head drop evaluation result can be the cigarette head drop detection result of multiple batches of cigarettes. Specifically, for each batch of cigarettes, a preset number of anti-twisting ability parameters and density parameters of the cigarettes to be tested can be obtained from the batch of cigarettes. Finally, the anti-twisting ability parameters and density parameters of the cigarettes to be tested in multiple batches of cigarettes are statistically analyzed to obtain the cigarette head drop evaluation result. In addition, the anti-twisting ability parameters and density parameters of each cigarette to be tested can also be analyzed to obtain analysis results such as head drop probability, anti-fracture analysis results and density analysis results. Finally, the analysis results of the cigarettes to be tested in multiple batches of cigarettes are summarized to obtain the cigarette head drop evaluation result.
[0065] Compared with the prior art, the present invention has the following advantages:
[0066] 1. The present invention performs mechanical property testing on unburned cigarettes, thereby reducing the cigarette head falling detection process during the combustion process.
[0067] 2. Non-combustion process detection reduces the consumption of cigarettes and the emission of smoke and particles in combustion experiments, and is a more environmentally friendly detection method.
[0068] 3. The non-burning detection method reduces the use of experimental raw materials and makes it possible to reuse cigarette raw materials.
[0069] 4. It saves the time of cigarette burning process during the drop test and greatly reduces the detection time.
[0070] The technical solution provided by the embodiment of the present invention is as follows: by extracting a preset number of cigarettes to be tested from a target batch of cigarettes, performing a bending capacity test on the cigarettes to be tested, and obtaining bending capacity parameters corresponding to the cigarettes to be tested; performing a tensile capacity test on the cigarettes to be tested, and obtaining tensile capacity parameters corresponding to the cigarettes to be tested; performing a compressive capacity test on the cigarettes to be tested, and obtaining compressive capacity parameters corresponding to the cigarettes to be tested; determining the first test result according to the bending capacity parameter, the tensile capacity parameter and the compressive capacity parameter; acquiring a CT image of the cigarettes to be tested, and determining the axial overlap and porosity of the cigarettes to be tested according to the CT image; determining the second test result according to the axial overlap and porosity of multiple cigarettes to be tested; and determining the target head drop detection result corresponding to the target batch of cigarettes according to the first test result and the second test result. The technical solution of the embodiment of the present invention solves the problem that the prior art requires that cigarette end analysis be performed when the cigarette is burning, which results in a cumbersome process, a long detection cycle and high destructiveness. The technical solution of the embodiment of the present invention can perform multi-angle detection on unburned cigarettes to determine the target end detection results, thereby reducing the number of cigarette end detection procedures, reducing the detection time, reducing the use of experimental raw materials, and making it possible to reuse cigarette raw materials.
