Description

Technical Field

[0001] This utility model relates to the field of cigarette technology, and in particular to a cigarette force collapse resistance measurement system based on the change of draw resistance value. Background Technology

[0002] A cigarette empty end refers to a void of a certain area and depth at the end of a cigarette due to insufficient tobacco filling. GB5606 classifies empty ends as a Class A quality defect. Empty ends are correlated with indicators such as tobacco filling value, structure, and moisture content. Impacts during cigarette transportation or heat during combustion can cause tobacco to collapse, resulting in empty ends. Additionally, some tobacco consumers may intentionally press their cigarettes together to make the tobacco filling more compact, perhaps to enhance the smoking experience.

[0003] When tobacco shreds in a cigarette are subjected to force, a force collapse phenomenon occurs, which manifests as an increase in the cigarette's draw resistance, density, and porosity. Excessive draw resistance and porosity after force collapse can seriously affect consumer satisfaction. Therefore, conducting force collapse resistance testing on cigarettes can provide technical support for cigarette manufacturing and is of positive significance for improving cigarette consumer satisfaction.

[0004] Tobacco industry scientists have conducted extensive research on cigarette hollowness. GB / T22838.9 provides a method for determining cigarette hollowness, including opening the small pack, gently removing the cigarette, visually estimating the size of the hollow area of ​​the tobacco shreds on the cigarette end face, and using a cylindrical millimeter ruler to measure the hollow depth if the hollow depth is greater than 1 mm and the hollow cross-section ratio is greater than 2 / 3. GB / T22838.5 provides a method for determining cigarette draw resistance. However, the above methods provide static measurement results and cannot accurately reflect the actual force collapse hollowness that is likely to occur in cigarettes under unsteady stress conditions during consumption or transportation.

[0005] Regarding cigarette collapse, Chinese patent CN108634367A, published on October 12, 2018, discloses a non-contact measuring device and method for measuring cigarette thermal collapse; Chinese patent CN107183783A, published on September 22, 2017, discloses a high-efficiency filter that can prevent filter thermal collapse; and Chinese patent CN107087811A, published on August 25, 2017, discloses a low-temperature cigarette that reduces smoke temperature and prevents filter tip thermal collapse. However, these technologies are all methods for measuring cigarette collapse and fail to consider the impact of cigarette collapse on the user experience from the consumer's perspective.

[0006] In summary, regarding the indicators of cigarette hollowness or collapse, the aforementioned standards and patents can accurately measure cigarette hollowness, draw resistance, or thermal collapse during combustion under static or steady-state conditions. However, they do not fully achieve accurate measurement of force collapse under unsteady-state stress on cigarettes, based on key indicators of consumer concern. Utility Model Content

[0007] The primary objective of this invention is to provide a cigarette force collapse resistance measurement system based on the change in draw resistance value, which can simulate the force collapse situation of cigarettes under unsteady stress and calculate the change in draw resistance value.

[0008] This invention provides a cigarette force collapse resistance testing system based on changes in draw resistance value. The system comprises: a sample injection module and a draw resistance testing module, wherein the sample injection module delivers a cigarette to the draw resistance testing module, and the draw resistance testing module measures the draw resistance value of the cigarette; a drop module and a collection module, wherein the drop module is located at the outlet side of the draw resistance testing module, and the collection module is located at the outlet side of the drop module, so that the cigarette, after the draw resistance value is measured, falls onto the collection module and is collected, causing the cigarette to collapse under force; the cigarette collected by the collection module is then sent back to the sample injection module; and a data acquisition module, which is signal-connected to the draw resistance testing module and is used to acquire the draw resistance value of the cigarette measured by the draw resistance testing module.

[0009] Furthermore, the drop module includes a conduit, which is vertically disposed at the outlet of the suction resistance measuring module.

[0010] Furthermore, the dropping module includes a hopper, a conduit, and a rotary guide mechanism. The inlet of the hopper is located below the outlet of the suction resistance measuring module. The conduit is connected to the outlet of the hopper and is connected to the rotary guide mechanism.

[0011] Furthermore, the rotary guide mechanism includes a curved rail with graduated markings, and a roller is connected to the guide tube, the roller being movable and embedded in the curved rail.

[0012] Furthermore, the guide tube is provided with a positioning block, and a locking screw is threaded onto the positioning block. The locking screw abuts and locks against the curved rail.

[0013] Furthermore, the collection module includes a tray disposed below the conduit.

[0014] The technical solution of this utility model establishes a method for measuring the resistance to cigarette force collapse by setting a drop module on the outlet side of the suction resistance measurement module. The cigarette falls into the drop module and the tobacco collapses under vertical force, resulting in a change in the suction resistance value. This fills the gap in the measurement of cigarette force collapse resistance. The method is simple to operate, highly accurate, and requires no major modification to existing equipment. It can accurately reflect the differences in the resistance to cigarette force collapse, thereby providing a basis for improving the quality of cigarette products. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] like Figures 1-8As shown, this utility model provides a cigarette force collapse resistance measurement system based on the change of draw resistance value. It is characterized by comprising: a sample injection module 1 and a draw resistance measurement module 2, wherein the sample injection module 1 is used to deliver the cigarette to the draw resistance measurement module 2, and the draw resistance measurement module 2 is used to measure the draw resistance value of the cigarette; a drop module (including a conduit 3 vertically disposed at the outlet of the draw resistance measurement module 2) and a collection module (including a tray 4 disposed below the conduit 3), wherein the drop module is disposed at the outlet side of the draw resistance measurement module 2, and the collection module is disposed at the outlet side of the drop module, so that the cigarette after the draw resistance value is measured falls onto the collection module and is collected, causing the cigarette to collapse under force; the cigarette collected by the collection module is then sent back to the sample injection module 1; and a data acquisition module, which is signal-connected to the draw resistance measurement module 2 and is used to acquire the draw resistance value of the cigarette measured by the draw resistance measurement module 2.

[0039] Specifically, this utility model makes minor improvements to the cigarette comprehensive testing platform. It retains the automatic sample feeding module 1, the suction resistance measurement module 2, and the data acquisition system. A vertically placed cigarette guide tube 3 and a sample collection tray 4 are added to the outlet of the suction resistance measurement module 2. Several cigarettes are placed into the automatic sample feeding module 1, allowing them to pass sequentially through the suction resistance measurement module 2 and then fall vertically onto the tray 4 via the guide tube 3. The cigarette guide tube 3 can be made of glass, resin, stainless steel, etc., with a length of 300mm-1000mm, an inner diameter of 6mm-11mm, and a height of 90mm-100mm from the bottom of the guide tube to the drop end. The tray 4 can be made of stainless steel, iron, etc.

[0040] The dropping module includes a hopper 5, a guide tube 3, and a rotary guide mechanism 6. The inlet of the hopper 5 is located below the outlet of the suction resistance measuring module 2. The guide tube 3 is connected to the outlet of the hopper 5 and is connected to the rotary guide mechanism 6. The rotary guide mechanism 6 includes a curved rail 61 with graduation marks 62. A roller 31 is connected to the guide tube 3 and moves and is embedded in the curved rail 61. A positioning block 32 is provided on the guide tube 3, and a locking screw 33 is threaded onto the positioning block 32. The locking screw 33 abuts against the curved rail 61 and locks it in place. After the cigarette's draw resistance is measured in the draw resistance measurement module 2, it falls from the outlet into the hopper 5. Guided by the roller 31 in the curved rail 61, the tilt angle of the guide tube 3 and the hopper 5 can be changed when the guide tube 3 swings, thereby simulating the falling situation of the cigarette in different postures (such as vertical falling, 30-degree tilt falling, 60-degree tilt falling, etc.). When the guide tube 3 swings to a suitable angle through the scale mark 62, the locking screw 33 is tightened to lock it to the outer wall of the curved rail 61, thereby fixing the tilt angle of the guide tube 3.

[0041] In addition, in this embodiment, a valve can be installed at the outlet of the conduit 3. Specifically, a rotating sleeve 71 is installed on the outer wall of the outlet of the conduit 3, and a rotating shaft 72 is rotatably inserted into the sleeve 71. The bottom end of the rotating shaft 72 is connected to a baffle 73 as a valve, and the top end of the rotating shaft 72 is connected to a micro motor 75 for driving (via a gear mechanism 74). When the motor 75 drives the rotating shaft 72 to rotate and the baffle 73 to block the outlet of the conduit 3, the cigarette is temporarily stored at the outlet of the conduit 3. When the motor 75 drives the rotating shaft 72 to move the baffle 73 away from the outlet of the conduit 3, the cigarette falls from the outlet of the conduit 3. In this structure, a piezoelectric sensor 76 is installed on the baffle 73 to measure the amount of cigarette temporarily stored in the conduit 3 (by weight). When the amount of cigarette reaches a certain value, the baffle 73 is opened to release the cigarette. The wire 77 of the piezoelectric sensor 76 can be passed through a wire hole opened in the baffle 73.

[0042] In addition, the hopper 5 initially rotates to vertically receive the cigarettes falling from the suction resistance measuring module 2 and guides them into the conduit 3. When the cigarettes in the conduit 3 are measured to a certain value, the conduit 3 and the hopper 5 are rotated to simulate different falling angles.

[0043] Additionally, a conveying system can be installed after the collection tray 4 to transport the collection tray to the sample injection module, where the collected cigarettes are poured into the sample injection module for re-injection. The conveying system may include a lifting platform and a pushing device. The lifting platform raises the collection tray to the inlet side of the sample injection module, and the cigarettes in the collection tray are pushed out to the inlet of the sample injection module by means of, for example, pneumatic, hydraulic, or electric push rods.

[0044] This utility model also provides a method for determining the cigarette force collapse resistance based on the change of suction resistance value, including the following steps:

[0045] S1, Sample processing and information collection: Collect the cigarettes to be tested and equilibrate them in a set temperature environment of 22℃±2℃ and a set relative humidity environment of 60%±5% for a set time of 48h. Collect the filter rod length and corresponding pressure drop information of the cigarette samples.

[0046] S2, Sample Measurement: Several cigarettes of different brands (including regular cigarettes, slim cigarettes, and medium-sized cigarettes) are placed into the automatic sample feeding module 1 of the cigarette comprehensive testing platform. The cigarettes pass sequentially through the draw resistance measurement module 2 and then fall vertically through the drop module (including the conduit 3 vertically positioned at the outlet of the draw resistance measurement module 2) to the collection module (including the tray 4 positioned below the conduit 3). The initial average draw resistance P0 (closed-loop draw resistance measurement value) of the cigarettes is measured. The cigarettes in the collection tray 4 are sampled repeatedly (3-10 times), and the average draw resistance P0 of the cigarettes after different numbers of drops is measured. x .

[0047] S3, Sample Data Summary and Analysis: The test results are summarized and analyzed. The rate of change in draw resistance of different brands of cigarettes after the same number of cycles is calculated. The rate of change in draw resistance is used to characterize the differences in the resistance to force collapse of different brands of cigarettes. The calculation method for the rate of change in draw resistance is: ΔP X =(P X -P0) / P0×100%, the rate of change in draw resistance can be expressed as the rate of change in draw resistance of the entire cigarette ΔP. X Or the rate of change of draw resistance ΔP of short cigarettes (excluding the filter rod section) 短X .

Sample information was collected. The filter rod length of both A and B brand cigarettes was 25mm. The filter rods used in both A and B brand cigarettes were 100mm. The design pressure drop of the filter rod for brand A was 2646Pa, and the design pressure drop of the filter rod for brand B was 2620Pa.

The average draw resistance P0 of the cigarettes after each drop was measured. x .

[0051] (3) Sample data summary and analysis: The results of the cigarette draw resistance measurement are detailed in [link to sample data]. Figure 9 ,Depend on Figure 9 It can be seen that the average draw resistance of the cigarette gradually increases with the number of drops, mainly because the tobacco filling becomes more compact after the cigarette collapses under vertical force, resulting in increased draw resistance. After 5 to 6 cycles, the density change rate of the cigarette segment tends to stabilize.

[0052] The repeatability of the method was investigated by measuring the mean inhalation resistance of cigarettes after five parallel cycles for the same sample. The specific results are shown in Table 1. As can be seen from the table, the RSD of the five parallel measurements was less than 1%. The results indicate that the method has good accuracy.

The rate of change in draw resistance for brand A cigarettes was approximately twice that of brand B cigarettes. The results indicate that brand A cigarettes have significantly lower resistance to draw resistance collapse than brand B cigarettes, which could have a greater impact on the consumer satisfaction of brand A cigarette consumers, especially those who prefer a more robust draw resistance.

[0085] This invention, based on the characteristic that the collapse of tobacco shreds under a fixed-length vertical force or a tilted force with a changed direction leads to a significant increase in draw resistance, makes subtle improvements to the cigarette testing platform. This allows the cigarette to fall vertically or at a changed direction along the inner wall of the tube. The draw resistance measurement module in the cigarette testing platform measures the draw resistance before and after the force application, and the rate of change in draw resistance is used to characterize the difference in cigarette force collapse resistance. Based on the difference analysis of the rate of change in draw resistance after vertical drop or tilted force application, this invention provides a method for determining cigarette force collapse resistance based on the change in draw resistance, which can accurately characterize the differences in force collapse resistance among different cigarettes. This invention fills a gap in cigarette force collapse resistance measurement. This method can meet the testing needs of different cigarette specifications, including regular, medium, and slim cigarettes. Furthermore, the method is simple to operate, highly accurate, and can provide technical support for cigarette manufacturing.
