Description

Technical Field

[0001] The present invention belongs to the technical field of cigarettes, and particularly relates to a device and method for a mobile heating cigarette paper tube. Background Art

[0002] The composition of the cigarette paper tube has a crucial impact on the properties of the cigarette ash after combustion, such as the whiteness of the cigarette ash, the compactness of the ash column, and the component structure of the ash column. When the composition of the paper tube is slightly different, the difference in the ash performance after the paper tube burns may be very obvious. The difference in ash performance also indirectly affects the smoking experience of the smoker. Therefore, it is very necessary to test the combustion performance of the paper tube and then adjust the composition of the paper tube accordingly to improve the ash performance.

[0003] However, if cigarettes are directly used as test samples, on the one hand, the complexity of tobacco components has a great impact on the cigarette ash after combustion. After the cigarette burns, it is not known whether the test result of the whiteness of the cigarette ash is caused by tobacco components or paper tube components. On the other hand, even for the same batch of cigarettes, due to the influence during the tobacco mixing process, there are slight differences in the tobacco components of different cigarette samples, which leads to poor comparability between the test results of the cigarette ash after combustion of different cigarette samples.

[0004] Therefore, it is very necessary to separately examine the combustion performance of the cigarette paper tube. However, if the method of directly igniting the paper tube and then allowing it to burn spontaneously is used for examination, the test result has no practical reference value at all. The reasons are as follows: When a real cigarette with tobacco burns, the temperature of the combustion cone is about 850°C, while after igniting the paper tube, the self-ignition temperature of the paper tube is about 200°C, which is much lower than the temperature of the combustion cone when a real cigarette with tobacco burns. This results in, on the one hand, the test temperature being inconsistent with the real combustion temperature. More importantly, after igniting the paper tube and burning, what is obtained is black powder, not the same color as the cigarette ash after real cigarette combustion, and it has no reference significance for examining the properties such as the whiteness of the cigarette ash, the compactness of the ash column, and the component structure of the ash column after the paper tube burns. This is because when the temperature is about 200°C, the paper tube burns and carbonizes. Based on this, it is further considered to use a muffle furnace to detect the high-temperature carbonization of the cigarette paper, but it has the following problems: 1. Before sample injection, it is necessary to separately use other devices to remove the tobacco and filter tip, and the steps are cumbersome; 2. When the cigarette is directly placed in a container and detected in the muffle furnace, it is not convenient to observe the carbonization state of the paper tube during the detection process, and it is difficult to maintain the normal combustion form of the cigarette tube after detection for detecting related indicators such as the whiteness of the ash column and the compactness of the ash column during normal cigarette combustion; 3. The muffle furnace needs to heat up during the process and cannot well simulate the normal carbonization process of the cigarette and the temperature field during carbonization, resulting in large differences in the detection results of the whiteness of the ash column, the compactness of the ash column, and the component structure of the ash column.

[0005] In summary, designing a device that can truly simulate the combustion state of the paper tube during cigarette puffing and a method for developing and testing the combustion performance of the paper tube using this device is very important for the research on the combustion performance of paper tubes in the cigarette field.

[0006] To solve the above problems, the present invention is proposed. Summary of the Invention

[0007] The first aspect of the present invention provides a device for mobile heating of a cigarette paper tube, which includes a base 1, a steering assembly 2, and a lifting assembly 3;

[0008] The steering assembly 2 includes a steering roller 21 and a steering drive motor 22 connected thereto; the steering drive motor 22 drives the steering roller 21 to rotate; the steering roller 21 is provided with a plurality of cigarette holders 25, one end of the cigarette holder 25 fixes the cigarette by fixing the cigarette filter tip, and the other end is connected to the steering roller 21; an air vent pipe 23 is arranged inside the steering roller 21, one end of which is connected to a blowing valve 24 on the steering roller 21, and the other end is in air flow communication with the cigarette holder 25. When the blowing valve 24 is opened, ambient air can sequentially pass through the blowing valve 24, the air vent pipe 23, and the cigarette holder 25 and enter the cigarette interior;

[0009] The lifting assembly 3 includes a lifting plate 31 and a lifting drive motor 32 connected thereto; the lifting drive motor 32 drives the lifting plate 31 to move up and down; a heating rod 33 is fixed on the lifting plate 31, and a heating core 331 is provided at the head end of the heating rod 33 close to the steering assembly 2; the heating rod 33 moves up and down in the paper tube of the cigarette fixed at one end of the cigarette holder 25 driven by the lifting plate 31, and the heating core 331 can heat different positions of the cigarette paper tube;

[0010] The steering assembly 2 is fixed on the base 1 through a first support column 11; the lifting assembly 3 is fixed on the base 1 through a second support column 12.

[0011] Preferably, a tobacco collection box 13 is placed on the base 1, which is located below the steering roller 21.

[0012] Preferably, the outer diameter of the heating rod 33 matches the inner diameter of the paper tube of the cigarette. Here, the outer diameter of the heating rod 33 should be slightly smaller than the inner diameter of the paper tube of the cigarette to ensure that the heating rod 33 can move inside and outside the cigarette paper tube.

[0013] Preferably, the cigarette holder 25 includes a cigarette holder body 251, a pressing ring 252 and a swaging nut 253. The inside of the cigarette holder body 251 is a hollow structure allowing air flow through. The inside of the cigarette holder body 251 is divided into an air flow channel 254 and a cigarette accommodation cavity 255. One end of the cigarette holder body 251 is provided with a thread for connecting to the turning drum 22, and the other end is provided with a slotted taper thread. The pressing ring 252 is placed inside the cigarette accommodation cavity 255. The inner diameter of the pressing ring 252 is selected according to the diameter of the cigarette, and the outer ring of the pressing ring 252 matches the cigarette accommodation cavity 255. The swaging nut 253 is connected to the slotted taper thread of the cigarette holder body 251. By tightening the swaging nut 253, the slotted taper thread on the cigarette holder body 251 deforms to drive the pressing ring 252 to contract, thereby clamping the cigarette.

[0014] Wherein, the air flow channel 254 of each cigarette holder 25 communicates with the ventilation duct 23. When the blowing valve 24 is opened, compressed air or blowing is used to expel the tobacco in the cigarette. Specifically: when the blowing valve 24 is opened, outside air is introduced into the ventilation duct 23, and then through the air flow channel 254 and the filter tip of the cigarette in the cigarette accommodation cavity 255, the tobacco in the cigarette is expelled to form an empty tube.

[0015] Preferably, the device has two states. The first state is the preparation state: one end of the cigarette fixed by the cigarette holder 25 faces away from the heating rod 33. The blowing valve 24 is opened, and the blower connected to the blowing valve 24 blows the air in the environment into the ventilation duct 23, and then the tobacco in the cigarette is blown out through the cigarette holder 25 to obtain a cigarette paper tube. The second state is the heating state: one end of the cigarette fixed by the cigarette holder 25 faces the heating rod 33. The lifting drive motor 32 drives the lifting plate 31 to drive the heating rod 33 to move downward, so that the heating core 331 gradually moves from the end of the cigarette paper tube away from the filter tip towards the end close to the filter tip.

[0016] Preferably, the heating rod 33 is made of ceramic or metal alloy.

[0017] Preferably, the heating core 331 is made of a resistance wire selected from.

[0018] Wherein, the materials of the heating rod 33 and the heating core 331 are not limited to the above materials. Any materials that can heat the cigarette paper tube and can withstand a temperature of 1200 °C in the prior art can be used. The selection of the materials of the heating rod 33 and the heating core 331 can refer to the heating rods in the prior art of heat-not-burn cigarette smoking devices.

[0019] The second aspect of the present invention provides a method for mobile heating of a cigarette paper tube. Using the device for mobile heating of a cigarette paper tube, it includes the following steps:

[0020] (1) Fix the cigarette to the steering drum 21 through the cigarette holder 25, and the cigarette holder 25 fixes one end of the cigarette filter tip.

[0021] (2) Control the steering drive motor 22 to drive the steering drum 21 to rotate, so that one end of the cigarette fixed by the cigarette holder 25 faces away from the heating rod 33.

[0022] (3) Open the air blowing valve 24, and the blower connected to the air blowing valve 24 blows the air in the environment into the ventilation duct 23, and then blows out the tobacco in the cigarette through the cigarette holder 25 to obtain a cigarette paper tube without tobacco inside.

[0023] (4) Control the steering drive motor 22 to drive the steering drum 21 to rotate, and one end of the cigarette fixed by the cigarette holder 25 faces the heating rod 33.

[0024] (5) Control the lifting drive motor 32 to drive the lifting plate 31 to drive the heating rod 33 to move downward, so that the heating core 331 gradually moves from the end of the cigarette paper tube away from the filter tip to the end close to the filter tip.

[0025] Among them, in step (5), control the heating core 331 to heat the cigarette paper tube.

[0026] Preferably, in step (5), the temperature of the heating core 331 can be set to be adjustable within the range of 500 - 1200 °C according to the normal combustion temperature of cigarettes; the downward movement speed of the heating rod 33 is not lower than the normal combustion speed of the cigarette paper tube to be tested, and more preferably, slightly greater than the normal combustion speed of the cigarette paper tube to be tested, so as to ensure that the cigarette paper tube is continuously heated by the heating core 331 during combustion and avoid the cigarette paper tube burning downward by itself. The static combustion speed of the cigarette paper tube is the normal self-combustion speed of the single cigarette paper tube.

[0027] The heating rod 33 sets the temperature rising program of its head heating core 331 through an external program, and it can have a thermocouple inside, which can feedback the temperature of the heating core 331 to the display screen in real time, and the staff can adjust the temperature of the heating core 331 in real time according to the feedback temperature.

[0028] Preferably, a protective cover 4 is provided on the upper part of the device for mobile heating of the cigarette paper tube of the present invention. The protective cover includes a protective door 41 that can be freely opened and closed. An exhaust port 42 is provided at the top of the protective cover 4 for exhausting the smoke generated during the test.

[0029] In this embodiment, although after specifically improving the composition of the paper tube and applying it to real cigarettes, the tobacco composition will still have a certain impact on the ash color of the cigarette after combustion, the device of the present invention can first specifically investigate and adjust the composition of the paper tube.

[0030] The cigarette tube described in the present invention is the cigarette paper tube.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. The present invention designs a mobile device for heating cigarette paper tubes. By heating the cigarette paper tubes separately, the performance of the cigarette paper tube components during combustion is examined, so that the cigarette paper tube components can be improved more specifically, avoiding the influence of tobacco combustion inside the cigarette when examining the combustion performance of the cigarette paper tubes.

[0033] 2. The mobile device for heating cigarette paper tubes of the present invention has a steering assembly 2, which drives the steering roller 21 to drive the cigarette to rotate through the steering drive motor 22. The samples to be tested in the present invention are cigarettes in actual applications, not cigarette paper tubes without tobacco in the factory, so the device first obtains cigarette paper tubes without tobacco inside, and then heats the cigarette paper tubes to examine their combustion performance. The tobacco end of the cigarette of the present invention can be rotated, which can not only achieve the work of removing tobacco, but also meet the requirements of heating the cigarette paper tube.

[0034] 3. The mobile device for heating cigarette paper tubes of the present invention is provided with a blowing valve 24, one end of which is connected to the cigarette holder 25 on the turning roller 21 through the ventilation duct 23 inside the turning roller 21, and the other end is connected to the external blower, through which the ambient air is blown into the ventilation duct 23, and then the tobacco inside the cigarette is blown out of the paper tube through the cigarette holder 25 and the cigarette filter, so as to obtain a cigarette paper tube without tobacco inside.

[0035] 4. In the mobile heating device for cigarette paper tubes of the present invention, the cigarette holder 25 can fix the cigarettes on one hand, and more importantly, during the process of blowing out the tobacco, ensure that the cigarettes are still fixed on the turning roller 21 and are not affected by the blowing.

[0036] 5. The mobile heating device for cigarette paper tubes of the present invention controls the lifting drive motor 32 to drive the lifting plate 31 to drive the heating rod 33 to move downward, so that the heating rod 33 enters the cigarette paper tube and gradually moves toward one end of the cigarette filter. The process of the heat source moving from the end away from the filter to the end close to the filter during cigarette smoking is truly simulated. Compared with the static combustion of cigarette paper tubes, the measurement results of the present invention are more real and accurate.

[0037] 6. In a preferred embodiment of the present invention, the temperature of the heating core 331 of the present invention is adjustable within the range of 500 - 1200 °C, which is closer to the temperature of the combustion cone during the combustion of a cigarette with real tobacco. It truly simulates the combustion effect of the cigarette paper tube during the combustion of a cigarette, avoiding the problem of carbonization of the paper tube caused by the fact that when directly lighting a paper tube without tobacco inside, after lighting the paper tube, the self-ignition temperature of the paper tube cannot reach the temperature of the combustion cone during the combustion of a cigarette with real tobacco. After lighting the paper tube, the self-ignition of the paper tube is the same as the effect of directly lighting paper, and then black powder is obtained, which has no reference significance for investigating the properties such as the whiteness of the cigarette ash, the compactness of the ash column, and the component structure of the ash column after the combustion of the paper tube.

[0038] 7. In a preferred embodiment of the present invention, the downward movement speed of the heating rod 33 of the present invention is not lower than the normal combustion speed of the cigarette tube to be tested, and this speed can be adjusted by controlling the lifting drive motor 32. At the same time, the downward speed can be further set in a segmented manner, that is, the downward speeds are inconsistent, which can more truly simulate the problem that the combustion speeds of the paper tube during suction and static combustion are inconsistent during the real suction process.

DETAILED DESCRIPTION OF THE INVENTION

[0045] The present invention will be further described below with reference to examples, but the present invention is not limited in any way. Any transformation or replacement based on the teachings of the present invention falls within the protection scope of the present invention.

[0046] Example 1

[0047] In this example, the mobile heated cigarette paper tube device of the present invention is used to test the ash color of different cigarette samples after the cigarette paper tubes are burned, which specifically includes the following steps:

[0048] (1) Fix the cigarette to the steering drum 21 through the cigarette holder 25, and the cigarette holder 25 fixes the filter tip end of the cigarette

[0049] (2) Control the steering drive motor 22 to drive the steering drum 21 to rotate, so that the end of the cigarette fixed by the cigarette holder 25 faces away from the heating rod 33;

[0050] (3) Open the air blowing valve 24, and the blower connected to the air blowing valve 24 blows the air in the environment into the ventilation duct 23, and then blows out the tobacco in the cigarette through the cigarette holder 25 to obtain a cigarette paper tube without tobacco inside;

[0051] (4) Control the steering drive motor 22 to drive the steering drum 21 to rotate, and the end of the cigarette fixed by the cigarette holder 25 faces the heating rod 33;

[0052] (5) Control the lifting drive motor 32 to drive the lifting plate 31 to drive the heating rod 33 to move downward, so that the heating core 331 gradually moves from the end of the cigarette paper tube away from the filter tip towards the end close to the filter tip;

[0053] Among them, in step (5), control the heating core 331 to heat the cigarette paper tube. The temperatures of the heating core 331 in step (5) are 800 °C and 900 °C respectively; the downward movement speed of the heating rod 33 is greater than the average combustion speed of directly igniting the empty cigarette tube. The average combustion speed of the empty cigarette tube is the average value calculated after igniting and carbonizing 5 empty cigarette tubes. The specific detection results are shown in Table 1.

[0054] Table 1 Detection results of the heating experiment of the empty cigarette tubes of cigarette samples

[0055]

[0056]

[0057] Under different detection conditions, the detection images of cigarette samples and corresponding cigarette tube samples are shown in Table 2.

[0058] Table 2 Combustion detection images and gray values of cigarette samples under various conditions

[0059]

[0060]

[0061] By calculating and comparing the image gray values under four conditions, namely, the static burning of a cigarette with tobacco, directly igniting the tobacco pipe, and burning the tobacco pipe at 800 °C and 900 °C using this device, it is found that the gray value of the tobacco pipe under the burning condition of 900 °C is similar to the gray value after the static burning of a normal cigarette. Taking the whiteness index of cigarette ash as an example in this embodiment, the closeness of this method to the static burning condition of a cigarette with tobacco is illustrated. This method is also applicable to the investigation of the burning performance of the tobacco pipe, such as the compactness of the ash column and the composition structure of the ash column.

[0062] It can be seen that this method can be used to simulate the high-temperature burning state of a cigarette tobacco pipe under the condition of containing tobacco shreds, eliminate the interference of complex factors of tobacco shreds, and simulate and realize the research on the influencing factors of the burning performance of cigarette paper on cigarettes, which has guiding significance for cigarette development and quality improvement.
