Description

Technical Field

[0001] This utility model belongs to the field of cigarette testing equipment, and specifically relates to a monitoring and comparison bar for a cigarette / filter testing platform. Background Technology

[0002] In the cigarette manufacturing industry, the physical properties of cigarettes, such as paper ventilation rate, mouthpiece ventilation rate, hardness, draw resistance (pressure drop), length, and circumference, directly affect the sensory quality and smoke indicators of cigarette products, and are key factors in ensuring the stability of cigarette product quality. Therefore, accurate and efficient measurement of these physical performance parameters is crucial for cigarette manufacturers.

[0003] Traditionally, the measurement of these parameters relies on various testing platforms. However, due to the wide variety of testing platforms, significant deviations can occur in the measurement results between different instruments. To ensure the accuracy and comparability of the measurement results, it is necessary to assess the degree of difference between different testing platforms through instrument comparison. However, the currently widely used cigarettes as comparison samples have obvious limitations: the quality of the samples themselves fluctuates greatly, and because they are for single use only, they cannot be reused. This not only increases the comparison cost but also reduces the reliability of the comparison results.

[0004] To ensure the stability and reliability of test results, effective calibration of the test bench is crucial. However, current technology lacks a sample that can both simulate the shape of a cigarette and possess similar physical properties, particularly covering important indicators such as paper ventilation rate and mouthpiece ventilation rate, to evaluate the accuracy of the test bench during use.

[0005] Although the applicant's project team designed a series of comparison rods in previously filed patents (such as 201010298172.3, 201020550160.0, 201120318963.8, and 201420864912.9) to solve many of the above problems, these designs still lack the ability to calibrate the two key indicators of paper ventilation rate and mouth ventilation rate. Summary of the Invention

[0006] The purpose of this invention is to address the lack of a means for calibrating cigarette testing platforms in the existing technology, and to provide a monitoring comparison rod for cigarette / filter testing platforms. This comparison rod can be used to calibrate the paper ventilation rate and mouthpiece ventilation rate measured by the cigarette testing platform, thereby ensuring the accuracy of the data measured by the cigarette testing platform.

Unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art.

[0038] like Figure 1 and Figure 2 As shown, the monitoring comparison rod for the cigarette / filter testing platform in this embodiment includes an outer tube 1, a central tube 2, a paper ventilation rate calibration component, and a mouthpiece ventilation rate calibration component. The outer tube 1 has a first through hole 101 and a second through hole 102 respectively opened along the axial direction; the central tube 2 is built into the lower part of the outer tube 1; the paper ventilation rate calibration component is built into the middle part of the outer tube 1 and corresponds to the position of the first through hole 101, and the paper ventilation rate calibration component is sealed and connected to the top of the central tube 2; the mouthpiece ventilation rate calibration component is built into the upper part of the outer tube 1 and corresponds to the position of the second through hole 102, and the mouthpiece ventilation rate calibration component is sealed and connected to the top of the paper ventilation rate calibration component.

[0039] Furthermore, in addition to calibrating the cigarette testing platform, this utility model can also be used to compare or monitor the testing performance of multiple cigarette testing platforms.

[0040] Furthermore, this invention can also be used for the calibration, comparison, and monitoring of other similar test benches, such as filter rod test benches.

[0041] like Figure 2 As shown, a porous layer 201 is sleeved between the inner walls of the central tube 2 and the outer tube 1. The porous layer 201 is made of a flexible material. Preferably, the porous layer 201 is made of sponge.

[0042] like Figure 3 and4 As shown, the paper ventilation rate calibration assembly includes a first fixing sleeve 301, a first collar 303, a suction resistance constant current tube bundle 302, and a paper ventilation rate constant current tube 304. The first fixing sleeve 301 is fastened and sealed to the top of the central tube 2; the lower end of the first collar 303 is sealed and snapped between the outer wall of the upper end of the first fixing sleeve 301 and the inner wall of the central tube 2, and the inner diameters of the first fixing sleeve 301 and the first collar 303 are equal; the suction resistance constant current tube bundle is simultaneously fitted inside the first fixing sleeve 301 and the first collar 303; multiple paper ventilation rate constant current tubes 304 are uniformly fixed along the circumferential direction on the outer edge of the top of the first collar 303.

[0043] Furthermore, the suction resistance constant current tube bundle is formed by bonding multiple suction resistance constant current tubes 304 together. The number and size of the suction resistance constant current tubes 304 can be selected according to the actual needs.

[0044] Optionally, the suction-resistance constant current tube bundle is bonded in the first fixed sleeve 301 and the first collar 303.

[0045] Furthermore, the top of the first ring 303 is provided with a first flange 3031 that fits tightly against the inner sidewall of the outer tube 1, and the first flange 3031 is provided with a plurality of through first mounting holes 3032 along the circumferential direction, and the paper ventilation constant flow tube 304 is inserted into the first mounting holes 3032.

[0046] like Figure 2 and 4 As shown, multiple first through holes 101 are evenly distributed circumferentially on the side wall of the outer tube 1, and the first through holes 101 are located below the paper ventilation rate constant flow tube 304. Preferably, there are four first through holes 101.

[0047] like Figure 2 and 5 As shown, the mouth ventilation rate calibration component includes a second collar 401 and a mouth ventilation rate constant flow tube 402. The first flange 3031 at the top of the first collar 303 is sealed and fastened to the bottom of the second collar 401. Multiple mouth ventilation rate constant flow tubes 402 are fixedly arranged circumferentially on the outer edge of the top of the first collar 303.

[0048] Furthermore, the top of the second ring 401 is provided with a second flange 4011, and a plurality of second mounting holes 4012 are provided through the second flange 4011, and the nozzle ventilation constant flow tube 402 is inserted into the second mounting holes 4012.

[0049] like Figure 2 and 5 As shown, multiple second through holes 102 are evenly distributed circumferentially on the outer tube 1, and the second through holes 102 are located below the nozzle ventilation constant flow tube 402. Preferably, there are four second through holes 102.

[0050] like Figure 1 and Figure 3 As shown, caps are fastened to both ends of the outer tube 1. Specifically, the caps include an upper cap 502 and a lower cap 503. The upper cap 502 is pressed against the outer surface of the second ring 401 to prevent the central tube 2, the paper ventilation rate calibration component, and the nozzle ventilation rate calibration component from moving around in the outer tube 1, thus ensuring the stability of the overall structure.

[0051] Furthermore, both the upper cap 502 and the lower cap 503 have multiple evenly distributed air holes 501.

[0052] Furthermore, the sequentially arranged suction resistance constant flow tube 302, paper ventilation rate tube 304, and mouth ventilation rate constant flow tube 402 are, on the one hand, to simulate the actual cigarette structure, and on the other hand, to ensure that the smoke and air can flow constantly in the comparison bar, reduce the occurrence of turbulent gas, thereby improving the accuracy of the paper ventilation rate and mouth ventilation rate test results.

[0053] The working principle is as follows:

[0054] (1) Basic calculation methods for paper ventilation rate M and nozzle ventilation rate N:

[0055] In actual use, the comparison rod of this utility model is installed on a standard cigarette testing platform, and smoke is released at the lower cap 503. The testing platform detects and records the air pressure at the lower cap 503 as A1.

[0056] A negative pressure is applied at the upper cap 502. The flue gas flows through the porous layer 201, the central tube 2, the suction resistance constant flow tube 302, the paper ventilation rate constant flow tube 304 and the mouth ventilation rate constant flow tube 402, and then flows out from the upper cap 502.

[0057] At the same time, due to the presence of negative pressure, outside air is drawn into the outer tube 1 through the first through hole 101 and the second through hole 102, and flows through the paper ventilation rate constant flow tube 304 and the mouth ventilation rate constant flow tube 402 before flowing out from the upper cap 502.

[0058] The test bench detects and records the air pressure at the top cap 502, the first through hole 101, and the second through hole 102, and records them as A2, B, and C respectively;

[0059] Based on the air pressure data A1, A2, B, and C, the air pressure ratios of the upper cap 502, lower cap 503, first through hole 101, and second through hole 102 are calculated respectively, thereby obtaining the paper ventilation rate M and the nozzle ventilation rate N. The specific calculation process is related to the corresponding production standards and the built-in program of the test bench, and will not be elaborated here.

[0060] Furthermore, since there are multiple first through holes 101, a set of air pressure data B1, B2...B at the first through hole 101 can be obtained. nAccording to data B1, B2...B n The calculated average value is data B mentioned above, thereby improving the accuracy of the calculation results.

[0061] Similarly, since there are multiple second through holes 102, a set of air pressure data C1, C2...C can be obtained at the second through holes 102. n According to data C1, C2...C n The calculated average value is the data C mentioned above, thereby improving the accuracy of the calculation results.

[0062] After the comparison rod of this invention has been tested on a standard cigarette testing bench and the paper ventilation rate M and mouthpiece ventilation rate N have been calculated, it can be used for the calibration, comparison or monitoring of other cigarette testing benches to be tested.

[0063] (2) Specific use of this utility model:

[0064] 1. Install the comparison rod of this utility model on the cigarette test stand to be tested, and measure the paper ventilation rate M1 and mouthpiece ventilation rate N1 of the cigarette test stand to be tested according to the above method. Compare the data M and M1 and the data N and N1 respectively. If M and M1 (or N and N1) are not equal, the cigarette test stand to be tested needs to be adjusted until M and M1 (and N and N1) are equal, so as to achieve the calibration of the cigarette test stand to be tested.

[0065] 2. Install multiple identical (or the same) comparison rods onto multiple cigarette testing tables to be tested, and measure a set of paper ventilation rates M2, M3...M n And a group of mouth ventilation rates N2, N3...N n By comparing the differences between the two sets of data, the testing performance of multiple cigarette testing stations can be compared.

[0066] 3. Install the comparison rod onto the cigarette testing platform. The cigarette testing platform outputs the paper ventilation rate and mouthpiece ventilation rate to the host computer in real time, thereby enabling the host computer to monitor the cigarette testing platform.
