Description

Technical Field

[0001] The invention relates to the technical field of tobacco strands, and in particular to a stress induction feedback type tobacco strand sampling device. Background Art

[0002] Cellulose diacetate tow and polypropylene tow are widely used tobacco tows in the industry. Filter rods processed with different tow specifications have different physical indicators such as filtration efficiency, hardness, and pressure drop, which in turn affect the quality of cigarettes. However, the tow is easily pulled and deformed during the sampling process, resulting in fluctuations in the physical properties of the tow such as the linear density, single-filament linear density, breaking strength, and number of crimps that affect the quality of the filter rod forming. This makes the test data unable to objectively reflect the current production situation and play a role in guiding production. Therefore, the industry standard YC / T 26-2017 "Tobacco Tow" has strict regulations on the technical requirements, sampling methods, and test methods for tobacco tows. However, from the current sampling situation, it is rare to accurately sample according to the quantity specified in the standard. When sampling, either too little or too much is taken. Most of the time, too much sampling is taken, and the sampling quality cannot be guaranteed.

[0003] Currently, the commonly used tobacco tow sampling tools have different shapes and materials. The retrieved tow samples are of various types. In addition, there are different amounts of tow wrapped around each plate. In addition, many sections of tow are stretched, broken, twisted, etc. in the extracted samples and cannot meet the testing requirements.

[0004] Taking the physical indicators of tobacco tow, such as the density of the tow and the density of the single yarn, as an example, YC / T 26-2017 Tobacco Tow requires that "about 60m of tow should be naturally rolled up along the laying direction with a sampling plate from the sampling position, and then sealed in a clean ziplock bag for storage. The state of the tow should not be damaged during sampling, transportation and storage."

[0005] When sampling tobacco tow, usually, 30m of tow is wound on a sampling board. Take 2 boards as required to get a test sample of 60m of tow. One sample needs to take 6 boards, about 180m of tow. In order to ensure the representativeness of sampling and testing, the samples need to be randomly intercepted from the laboratory samples, and all the test samples cannot be concentrated in a certain part of the 60m laboratory sample. Usually, there is at least 30 to 50cm between each sample to avoid continuous sampling.

[0006] If the tow is pulled or deformed during sampling, resampling is required, resulting in waste. If resampling is not done, only some intact tow parts can be selected for inspection of items specified in the standard. The experimental data fluctuates greatly, and there is a risk of misjudgment of product quality. If too much sampling is done, it ensures that the effective sample length meets the test needs, but it will cause waste and does not meet the requirements of lean management.

[0007] During sampling, some sampling plates have too many entangled wire bundles, which are squeezed by each other and stick together, causing the wire bundles to twist, break and straighten. During the sampling process, some samples have uneven force, resulting in wire bundles stretching, folding and knotting. Damage to the wire bundle specimens will result in insufficient effective sample length.

[0008] The quality of the extracted tow sample is the key to ensure the accuracy of the test results. Since the tow is easily pulled and deformed during the winding process, it will affect the quality test results of various indicators. Therefore, a stress sensing feedback type tobacco tow sampling device is provided. Summary of the invention

[0059]

[0060]

[0061] The relative deviation between the sampling length and the planned length is ≤5%, the accuracy of the sampling length is guaranteed and meets the requirements.

[0062] It has been verified that the relative deviation between the measured bundle linear density of the tobacco bundle samples and the nominal bundle linear density is ≤5%, and the validity of the bundle linear density of the sample is guaranteed, that is, the bundle is not stretched; the relative deviation between the sampling length and the planned length is ≤5%, and the accuracy of the sampling length is guaranteed and meets the requirements.

[0063] Effectiveness Examination

[0064] After implementation, 6 samples of yarn bundles of two specifications, 3.33dtex / 3.89Ktex and 3.50dtex / 3.56Ktex, were selected, and the yarn bundle linear density, single yarn linear density, moisture regain and acetone index involved in the product standards were tested. The test data were compared with the test data without using the modified sampling tool, as shown in the table below. The statistical results of the standard deviation and coefficient of variation of each indicator are smaller than before use.

[0065]

[0066] The two figures showing the standard deviation statistics before and after using the combined tow counting sampling plate are comparison charts of standard deviation and coefficient of variation for evaluating the stability of the test data. The smaller the statistical value, the more stable the test data. The stability of the tow samples is better when sampling using the new combined tow counting sampling plate developed.
