[0002] Existing abrasion resistance testing and analysis methods and systems used in thermal paper production have the following specific shortcomings when performing testing and analysis:

[0003] Existing methods and systems for testing and analyzing the abrasion resistance of thermal paper production are limited in their approach. They rely on the appearance of the thermal paper (such as friction smoothness and surface flatness) to determine its abrasion resistance. However, this method has low accuracy and cannot provide a comprehensive and effective assessment of the thermal paper's abrasion resistance.

[0004] Existing testing methods for thermal paper are highly consistent, typically involving testing specific points (such as the midpoint) and judging the condition of the thermal paper based on the test results of these specific points. However, this method has low testing stability and makes it difficult to comprehensively judge the condition of the thermal paper.

[0005] Currently, the testing process relies heavily on manual labor. For example, the flatness of thermal paper surfaces is usually assessed through manual observation, which is highly susceptible to human error and prone to inaccurate results.

[0006] Therefore, we propose a method and system for abrasion resistance testing and analysis in the production of thermal paper. Summary of the Invention

[0037] ;

[0038] The printed image of the friction sample is evaluated to obtain the retention evaluation value of the friction sample, which is denoted as mpg. The printing wear rate dms is calculated based on the retention evaluation value of the friction sample and the printing performance evaluation value pgz of the thermal paper sample.

[0061] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0062] Please see Figure 1 This invention relates to a method for testing and analyzing the wear resistance of thermal paper in production, belonging to the field of industrial data analysis. The invention provides a technical solution: a method for testing and analyzing the wear resistance of thermal paper in production includes:

[0063] Step S1: Sample the produced thermal paper to obtain thermal paper samples, and pre-process the thermal paper samples;

[0064] Step S11: Select consecutive batches of finished thermal paper from the thermal paper production line. Randomly sample multiple times from each batch to obtain thermal paper samples. Number the thermal paper samples according to the sampling batch, and label them as ypp1 to ypp1. as; among which ypp as This refers to the first batch of thermal paper samples.

[0065] Step S12: Pre-treat the thermal paper samples, place all batches of thermal paper samples in a standard environment for adjustment, and test the abrasion resistance of the thermal paper based on the adjusted thermal paper samples.

[0066] It should be noted that: standard environment refers to the temperature and humidity environment used for conditioning and testing of samples or specimens according to standard specifications. my country and other countries around the world have established standard environments based on their own climatic conditions. In my country, the general standard environment conditions are 23℃±2℃ and relative humidity 45%~55%. By conditioning the samples to a standard environment, the detection errors caused by different environments are reduced, thus enhancing the accuracy of thermal paper testing.

[0067] Step S2: Perform initial state detection on the thermal paper sample to obtain initial information, acquire the usage information of the thermal paper, conduct a friction experiment on the thermal paper sample based on the usage information of the thermal paper, detect the friction state of the thermal paper based on the friction experiment, and obtain friction information;

[0068] Step S21: Initial state detection of the thermal paper sample is performed. The weight of the thermal paper sample is detected by a high-precision electronic balance, the coating thickness of the thermal paper sample is measured by a coating thickness gauge, the smoothness of the thermal paper sample is detected by optical reflection, and an image of the thermal paper sample is printed by a thermal printer. The grayscale value of the printed image is measured to evaluate the printing performance of the thermal paper sample. The initial information of the thermal paper sample is composed of the weight, smoothness, coating thickness and printing performance.

[0069] Step S211: Obtain the quantity of thermal paper samples in each batch, denoted as bs; weigh each thermal paper sample according to the quantity of thermal paper samples to obtain the thermal paper sample weight yzl. a (b); yzl a (b) represents the weight of the bth thermal paper sample in the ath sampling batch;

[0070] Please see Figure 2 Step S212: Obtain the center point of the thermal paper sample, and connect the vertices of the thermal paper according to the center point of the thermal paper sample to obtain the connecting line;

[0071] Draw a perpendicular line from the center point of the thermal paper sample to the edge of the thermal paper. Count the connecting lines and perpendicular lines of the thermal paper. Divide the connecting lines and perpendicular lines from the upward perpendicular line to the downward perpendicular line in a clockwise direction into equal parts with a tolerance of 1. Obtain the division points and select the outermost division point as the detection point.

[0072] Divide the line from the downward perpendicular to the upward perpendicular into equal parts in a clockwise direction to obtain equal division points. Select the innermost division point as the detection point.

[0073] The coating thickness at the test points is measured, and the average value of the measurement results is taken as the coating thickness of the thermal paper sample.

[0074] It should be noted that: equal division means taking the center point as the starting point and dividing the upward vertical line into equal parts by increasing the tolerance percentage, i.e., bisection. When the next connecting line is encountered, the equal parts continue to increase, i.e., the connecting line is trisectioned. By using equal division points, multiple points are detected on the thermal paper sample to ensure the accuracy of the measurement. At the same time, by selecting equal division points on the outer and inner sides respectively, the detection points of the thermal paper sample are more comprehensive.

[0075] Step S213: The smoothness of the thermal paper sample is tested. Using a spectrophotometer, the surface of the thermal paper sample is irradiated at a specific angle (e.g., 45°), and the reflectance in the normal direction of the thermal paper sample surface is measured. The reflectance is statistically analyzed to obtain the smoothness of the thermal paper sample.

[0076] It should be noted that the uniformity and quality of the thermal coating can be assessed by analyzing the reflectance data of the thermal paper sample. Higher reflectance indicates a smoother paper surface and a more uniform thermal coating; conversely, lower reflectance suggests uneven coating or poor quality.

[0077] Please see Figure 3 Step S214: Print an image of the thermal paper sample using a thermal printer. Divide the thermal paper sample into units according to the printed content to obtain is×js printing units. Measure the grayscale value of each printing unit to obtain the unit grayscale value dhd(i,j); dhd(i,j) represents the grayscale value of the printing unit in the i-th row and j-th column. Perform printing weight analysis on each printing unit and set the printing weight according to the position of the printing unit to obtain the printing weight dqz(i,j).

[0078] ;

[0079] It should be noted that the weights of different positions are calculated based on the number of printing units. The monotonicity of the calculation results is adjusted by subtracting from 1, so that the weights satisfy the following: the left-hand printing unit has a greater weight than the right-hand unit, and the top printing unit has a greater weight than the bottom printing unit. (Printed text is usually from left to right and from top to bottom, so the upper left corner of thermal paper is used more frequently than the lower right corner. A higher weight is assigned to the frequently used position for calculation.) By setting the weights, the printing performance of the thermal paper sample can be evaluated more accurately.

[0080] The printing performance of the thermal paper sample is evaluated and calculated based on the unit gray value dhd(i,j) and the printing weight dqz(i,j), and the evaluation value pgz of the printing performance of the thermal paper sample is obtained.

[0081] ;

[0082] It should be noted that: calculating the unit grayscale value by printing weights to evaluate the printing performance of thermal paper samples enhances the accuracy of the evaluation. At the same time, calculating the evaluation values ​​of multiple units facilitates subsequent comparison of friction on thermal paper samples, simplifying the judgment process.

[0083] Step S22: Based on the usage information of the thermal paper, obtain the external friction factors that the thermal paper is subjected to in actual use, conduct a friction experiment on the thermal paper based on the external friction factors, detect the friction state of the thermal paper based on the friction experiment, obtain friction information, and calculate the wear rate of the thermal paper sample by combining the initial information of the thermal paper sample.

[0084] Step S221: Based on the external friction factors experienced by the thermal paper in actual use, obtain the friction parameters of the thermal paper, set the Taber abrasion tester according to the friction parameters, realize the external friction experienced by the thermal paper in actual use, collect the thermal paper sample after friction, and obtain the friction sample.

[0085] It should be noted that the Taber abrasion testing machine is based on the principle of rotational abrasion, and its core design includes a rotating platform and one or more abrasion wheels. During testing, the sample is fixed on the rotating platform, and the abrasion wheels contact the sample surface under a preset pressure, generating friction as the platform rotates. This motion simulates the wear scenarios that materials may face in actual use, such as friction and scratching. By measuring the mass difference of the sample before and after the test or observing changes in surface morphology, the abrasion resistance of the material can be quantitatively evaluated.

[0086] Step S222: Measure the weight, smoothness, coating thickness, and printing performance of the friction sample to obtain friction state data. Calculate the wear rate of the thermal paper sample by combining the friction state data with the initial information of the thermal paper sample. Evaluate the wear of the thermal paper based on the wear rate of the thermal paper sample.

[0087] Step S2221: Obtain the weight mzl of the friction sample. a (b); mzl a (b) represents the weight measured after rubbing the b-th thermal paper sample in the a-th sampling batch; based on the weight mzl of the rubbed sample. a (b) Combined with the weight yzl of the thermal paper sample a (b) Calculations were performed to obtain the weight abrasion rate zms of the thermal paper sample.a ;

[0088] ;

[0089] Where: bs represents the number of thermal paper samples in each batch;

[0090] It should be noted that the friction and wear of thermal paper is fed back by the weight wear rate, which accurately reflects the wear of thermal paper in the weight direction.

[0091] Step S2222: Obtain the smoothness of the friction sample, calculate the ratio between the smoothness of the friction sample and the smoothness of the thermal paper sample, and obtain the smoothness wear rate pms.

[0092] Step S2223: Obtain the coating thickness of the thermal paper sample and denote it as ytc; perform multi-point detection on the friction sample and count the number of friction detection points cs; obtain the friction point thickness mdh(c) based on the number of friction detection points; calculate the thickness wear based on the friction point thickness mdh(c) and the coating thickness ytc of the thermal paper sample to obtain the thickness wear rate hms.

[0093] ;

[0094] Step S2224: Evaluate the printed image of the friction sample to obtain the retention evaluation value of the friction sample, and record the retention evaluation value of the friction sample as mpg; calculate the printing wear rate dms based on the retention evaluation value of the friction sample and the printing performance evaluation value pgz of the thermal paper sample.

[0095] .

[0096] It should be noted that the retention evaluation value in this application document is the grayscale value of the image after the friction test, which corresponds to the evaluation value of the printing performance of the thermal paper sample. The calculation process is consistent and reflects the image retained after the thermal paper is rubbed.

[0097] Step S3: Statistically analyze the wear rate of thermal paper, construct an wear resistance model based on the wear rate of thermal paper, and evaluate the wear resistance level of thermal paper through the wear resistance model;

[0098] Step S31: Obtain the wear rate of thermal paper in terms of weight, smoothness, coating thickness and printing performance; calculate the weight of weight, smoothness, coating thickness and printing performance based on the wear rate to obtain the wear weight; construct an anti-wear model based on the wear weight and wear rate.

[0099] Step S311: Obtain the wear rate of different batches of thermal paper samples in terms of weight, smoothness, coating thickness, and printing performance, and obtain the weight wear rate zms. a Smoothness wear rate (pms) a Thickness wear rate (hms) a With print wear rate dms a ;

[0100] Among them: zms a This represents the weight abrasion rate of the a-th batch of thermal paper samples, expressed in pms. a The smoothness wear rate of the a-th batch of thermal paper samples is represented by hms. a The thickness wear rate of the thermal paper sample in batch a is represented by dms. a This indicates the printing wear rate of the a-th batch of thermal paper samples.

[0101] Step S312: Based on the wear rate of different batches of thermal paper samples, obtain the maximum value of weight wear rate, the maximum value of smoothness wear rate, the maximum value of thickness wear rate, and the maximum value of printing wear rate. Based on the maximum values ​​of weight wear rate, smoothness wear rate, thickness wear rate, and printing wear rate, set the weights for weight, smoothness, coating thickness, and printing performance.

[0102] The specific weight settings are as follows:

[0103] The maximum value of the weight wear rate is denoted as zmx, the maximum value of the smoothness wear rate is denoted as pmx, the maximum value of the thickness wear rate is denoted as hmx, and the maximum value of the printing wear rate is denoted as dmx.

[0104] The weight of the wear rate is calculated to obtain the weight wear weight zqz;

[0105] ;

[0106] The weight of the smoothness wear rate is calculated to obtain the smoothness wear weight pqz;

[0107] ;

[0108] The thickness wear rate weight is calculated to obtain the thickness wear weight hqz;

[0109] ;

[0110] The weight of the print wear rate is calculated to obtain the print wear weight dqz;

[0111] ;

[0112] Step S313: Obtain the weight wear weight zqz, smoothness wear weight pqz, thickness wear weight hqz, and printing wear weight dqz; combine the weight wear rate zms, smoothness wear rate pms, thickness wear rate hms, and printing wear rate dms; construct the wear resistance model msm.

[0113] ;

[0114] It should be noted that by subtracting from 1, the greater the wear rate, the smaller the calculation result of the wear resistance model, which makes it easier to intuitively demonstrate the wear resistance of thermal paper.

[0115] Step S32: The thermal paper sample is scored for wear resistance according to the wear model. The wear resistance of the thermal paper is classified into different levels based on the wear resistance score. The wear problems of the thermal paper are displayed according to the classification level.

[0116] The thermal paper samples are scored for wear resistance based on the values ​​obtained from the wear resistance model MSM. The wear resistance scores are divided into 4 levels. The levels are obtained based on the wear resistance scores. The wear problems of the thermal paper samples are analyzed based on the levels to determine the source of the problems. The number of problems is determined based on the levels. The wear problems of the thermal paper are presented in combination with the source of the problems.

[0117] It should be noted that the wear resistance model MSM yields values ​​from 0 to 100. If the value is 80, the wear resistance score is 80.

[0118] For the first level, identify and demonstrate the greatest wear impact caused by weight, smoothness, coating thickness, and printing performance; for the second level, identify and demonstrate two sources of problems.

[0119] Step S4: Monitor the production of thermal paper in real time, judge the wear resistance of thermal paper by combining the wear resistance model, deal with problems in the production process, and optimize the production process of thermal paper.

[0120] Step S41: Monitor the production of thermal paper in real time, check the abrasion resistance of thermal paper using an abrasion resistance model, compile statistics on the abrasion resistance test results, and address the abrasion problems of thermal paper based on the abrasion resistance test results.

[0121] Step S42: Analyze the processed thermal paper production to determine the change in the thermal paper's abrasion resistance score. If the thermal paper's abrasion resistance score increases, optimize the thermal paper production based on the analysis results.
