[0045] like Figure 1 As shown, the method for evaluating the compatibility between a cloth tape and a cigarette making machine provided in this embodiment includes the following steps in actual implementation:

[0046] Step S1: Determine an evaluation index for the compatibility between the cloth tape and the cigarette making machine, wherein the evaluation index includes at least one of a lifespan index, a quality index, a shutdown index, and a strip running index.

[0047] The cigarette making machine includes the ZJ118 model. The lifespan indicator includes the time it takes for a cloth belt to be installed and produced until its end of life. The quality indicator includes the number of cigarettes with broken ends rejected by the cigarette making machine within an 8-hour production shift. The shutdown indicator includes the number of cigarette machine shutdowns caused by the cloth belt within an 8-hour production shift. The stripping indicator includes the weight of stripped cigarettes caused by the cloth belt within a production shift.

[0048] Step S2: Calculate the quantitative score of each evaluation indicator.

[0049] In one embodiment of the method for evaluating the compatibility of a cloth tape with a cigarette making machine of the present invention, step S2 may specifically include:

[0050] Step S21: Determine the quantitative calculation formula for each evaluation index.

[0051] Specifically, the quantitative calculation formula of the quality index includes:

[0052] The full score of the quality index is 100 points. If the number of cigarettes with cracked ends rejected by the cigarette making machine is less than 5 within a production shift (8 hours), no points will be deducted. If the number of cigarettes with cracked ends rejected by the cigarette making machine is greater than 5, 5 points will be deducted for each additional cigarette rejected. The quality index score is expressed by the following formula:

[0053] Quality index score = 100-(number of cigarettes with broken holes removed-5)*5.

[0054] Furthermore, the quantitative calculation formula of the shutdown number index includes:

[0055] The maximum score for the number of downtime indicators is 100 points. If the number of downtimes caused by the cloth belt does not exceed 5 times within one production shift (8 hours), no points will be deducted. If the number of downtimes exceeds 5 times, 5 points will be deducted for each additional downtime. The score for the number of downtime indicators is expressed by the following formula:

[0056] The score of the number of downtime indicators = 100-(number of downtimes caused by tape-5)*5.

[0057] Furthermore, the quantitative calculation formula of the running bar index includes:

[0058] The full score of the strip running indicator is 100 points. If the weight of strip running caused by the cloth belt in the cigarette making machine does not exceed 5kg within a production shift (8 hours), no points will be deducted. If the weight of strip running exceeds 5kg, 5 points will be deducted for every additional 1kg of strip running weight. The strip running indicator score is expressed by the following formula:

[0059] Running bar index score = 100-(running bar weight caused by tape-5)*5.

[0060] Step S22: Calculate the quantitative score of each evaluation indicator according to the quantitative calculation formula.

[0061] Specifically, after the cloth tape is installed, one production shift is carried out, and the quantitative score of each evaluation indicator is calculated according to the quantitative calculation formula corresponding to each evaluation indicator.

[0062] In one embodiment of the present invention, an experiment was conducted on a cigarette making machine. After installing the cloth tape, production began, and the quantitative scores for each evaluation indicator were calculated after the shift. Specifically, the quality indicator was obtained by reviewing the rejection records for a cigarette making machine with a specified serial number on that day, over a production shift (8 hours). The rejection records showed that the number of cigarettes with cracked ends was 6. Therefore, the quality indicator score = 100 - (6 - 5) * 5 = 95 points.

[0063] The downtime index is calculated by checking the number of downtimes caused by belts within an eight-hour production shift for a given cigarette making machine on that day. For example, if the number of downtimes caused by belts is 6, the downtime index score is 100 - (6 - 5) * 5 = 95 points.

[0064] The slip index is calculated by weighing the amount of slip caused by the fabric belt during an eight-hour shift. Specifically, if the weight of slip caused by the fabric belt during an eight-hour shift is 7 kg, the slip index score is 100 - (7 - 5) * 5 = 90 points.

[0065] Step S3: determining the functional relationship between the matching between the cloth tape and the cigarette making machine and each of the evaluation indicators.

[0066] Specifically, based on the quantitative scores of the evaluation indicators, the total score of the matching between the cloth tape and the cigarette making machine is determined by the following formula:

[0067] The total matching score = quality index score * 40% + downtime score * 30% + running index score * 30% + (lifespan is a veto item), where lifespan is a veto item, requiring the tape to be able to be used for at least one production shift. If the usage cycle is less than one production shift, the total matching score is 0.

[0068] Step S4: Evaluate the matching between the cloth tape and the cigarette making machine according to the functional relationship between the matching between the cloth tape and the cigarette making machine and each evaluation index and the quantitative score of each evaluation index to obtain an evaluation result.

[0069] In one embodiment of the method for evaluating the compatibility of a cloth tape with a cigarette making machine of the present invention, step S4 may specifically include:

[0070] Step S41: Substitute the quantitative scores of the evaluation indicators into the functional relationship between the matching between the cloth tape and the cigarette making machine and the evaluation indicators to obtain a total matching score, which is used to reflect the matching between the cloth tape and the cigarette making machine.

[0071] In one embodiment of the present invention, the quantitative scores of the evaluation indicators calculated in step S2 are substituted into the functional relationship determined in step S3 to obtain a total matching score. For example, if the life of the cigarette machine cloth belt exceeds one production shift (8 hours), the rejection condition is not met; and if the quality index score = 95 points, the number of downtime score = 95 points, and the strip running index score = 90 points, then the total matching score = quality index score (95) * 40% + number of downtime score (95) * 30% + strip running index score (90) * 30% = 93.5 points.

[0072] Step S42: Evaluate the matching between the cloth tape and the cigarette making machine according to the total matching score to obtain an evaluation result.

[0073] The evaluation results include whether the cloth tape does not match the cigarette making machine or whether the cloth tape matches the cigarette making machine.

[0074] Specifically, if the total matching score is less than 85 points, the evaluation result is that the cloth belt does not match the cigarette making machine;

[0075] If the total matching score is greater than or equal to 85 points, the evaluation result is that the cloth belt matches the cigarette making machine.

[0076] In one embodiment of the present invention, the total matching score (93.5) calculated in step S41 is greater than 85 points, which means that the cloth tape is determined to be compatible with the cigarette making machine.

[0077] The method for evaluating the matching of the cloth tape and the cigarette making machine provided in the embodiment of the present invention evaluates the matching of the cloth tape and the cigarette making machine according to the functional relationship between the matching between the cloth tape and the cigarette making machine and each evaluation index and the quantitative score of each evaluation index, and obtains an evaluation result, thereby providing a scientific evaluation method for the matching of the cloth tape and the cigarette making machine, guiding cigarette companies to select suitable cloth tapes for production during the production process, improve product quality, improve production efficiency, reduce equipment downtime, reduce the consumption of raw and auxiliary materials, and promptly discover factors that restrict the improvement of production and manufacturing levels, and carry out targeted upgrades and improvements, so that cigarette companies can continuously improve their production and manufacturing capabilities and reduce the consumption of raw and auxiliary materials, thereby promoting the high-quality development of cigarette companies.
