Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and in particular to a rapid testing device for tobacco leaves. Background Technology

[0002] In the tobacco processing industry, tobacco leaf aging is a crucial step in improving tobacco leaf quality. It makes the chemical composition of tobacco leaves more harmonious and the aroma more mellow, thus meeting the demand for high-quality raw materials in cigarette production. However, during the tobacco leaf aging process, "burning" and mold growth are important problems that urgently need to be addressed.

[0003] Tobacco aging typically involves stacking and packaging the tobacco leaves, sealing them within packaging materials, and allowing them to ferment naturally under specific temperature and humidity conditions. However, due to the complex aging environment and the difficulty in controlling local temperature and humidity, coupled with the ineffective dissipation of heat generated by the tobacco leaves' respiration, "packaging burns" are highly likely to occur. "Packaging burns" lead to excessively high local temperatures within the tobacco leaves, causing drastic changes in their chemical composition, resulting in carbonization, spoilage, and significant loss of aroma compounds. This severely impacts the quality and utilization rate of the tobacco leaves, causing substantial economic losses for tobacco companies.

[0004] Mold growth on tobacco leaves is a major problem in the tobacco aging process. Moldy tobacco leaves are generally not allowed to participate in the tobacco processing, which means that precious tobacco leaves are directly turned into waste tobacco leaves due to mold. If moldy tobacco leaves are not detected and enter the tobacco processing stage, it will also cause great damage to the tobacco products.

[0005] Currently, the detection of "burnt bales" during the tobacco aging process mainly relies on regular manual inspections and traditional temperature sensors. However, there are currently no effective on-site detection methods for mold, making mold a persistent challenge and bottleneck in quality control. Utility Model Content

[0006] Therefore, it is necessary to provide a rapid detection device for tobacco leaves to address the current difficulty in detecting moldy tobacco leaves.

[0007] The first aspect of this application provides a rapid testing device for tobacco leaves, comprising:

[0008] Sampling assembly, the sampling assembly being inserted into the cigarette pack to form a sampling space within the cigarette pack; and

[0009] A detection component, wherein the detection end of the detection component can be inserted into the sampling space, and the detection component is used to detect tobacco leaf data and / or environmental data within the sampling space.

[0010] In one embodiment, the sampling component includes a first clamp and a second clamp, the first clamp being movably connected to the second clamp, and a gap being formed between a first end of the first clamp and a first end of the second clamp to form a sampling space.

[0011] In one embodiment, a working space is formed between the second end of the first clamp and the second end of the second clamp, the working space being connected to the sampling space, and the detection end of the detection component being able to be inserted into the sampling space via the working space.

[0012] In one embodiment, the sampling assembly further includes a rotating member, wherein the first clamp is rotatably connected to the second clamp via the rotating member, and at least one of the first clamp and the second clamp rotates with the rotating member as a base point.

[0013] In one embodiment, the rotating component has a through hole that communicates with the sampling space, and the detection end of the detection component can be inserted into the sampling space through the through hole.

[0014] In one embodiment, the sampling component has an insertion state in which it can be inserted into the cigarette pack, wherein in the insertion state, a first end of the first clamp is close to a first end of the second clamp.

[0015] In one embodiment, both the first clamp and the second clamp are sheet-like structures.

[0016] In one embodiment, the detection component includes at least one of a first detection element and a second detection element, and the detection ends of both the first detection element and the second detection element can be connected to the sampling space. The first detection element is used to detect the tobacco leaf data, and the second detection element is used to detect the environmental data.

[0017] In one embodiment, the first detection device includes a sampling tube and an electronic nose. One end of the sampling tube is disposed in the sampling space, and the other end of the sampling tube is connected to the electronic nose. The electronic nose is used to detect the tobacco leaf data.

[0018] In one embodiment, the second detection element includes a thermometer, the detection end of which is located within the sampling space, and the thermometer is used to detect the environmental data.

[0019] In the aforementioned rapid tobacco leaf testing device, by setting up a sampling component and a detection component, the sampling component can be easily inserted into the sampling point of the tobacco pack. After being inserted into the sampling point of the tobacco pack, the sampling component creates a sampling space at the sampling point. Through this sampling space, the tobacco and its surrounding environment at the sampling point can be sampled and tested. The detection component can be connected to the sampling component. When the sampling component extends into the sampling point of the tobacco pack, the detection component can also extend into the sampling space. When the detection end of the detection component reaches the sampling space, the detection component can detect the tobacco leaves and their surrounding environment at that point, so as to conveniently obtain tobacco leaf data and environmental data within the sampling space.

[0025] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0026] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0027] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] Currently, the detection of "burnt bales" during the aging process of tobacco leaves mainly relies on regular manual inspections and traditional temperature sensors. However, there is no effective on-site detection method for mold, making mold a persistent challenge in quality control. Therefore, to enable comprehensive quality control of tobacco leaves during the aging process, a rapid tobacco leaf testing device is proposed.

[0029] like Figure 1 As shown in the illustration, this application provides a rapid tobacco leaf testing device, including a sampling component 10 and a detection component 20. The sampling component 10 is inserted into the sampling point of the tobacco bale and constructs a sampling space 17 at the sampling point. The sampling space 17 can contain the tobacco leaves to be sampled, as well as the environment in which the tobacco leaves are located. The detection component 20 is connected to the sampling component 10 and can extend into the sampling space 17 constructed by the sampling component 10. The detection component 20, extending into the sampling space 17, can sample the tobacco leaves to obtain tobacco leaf data. In addition, the detection component 20 can also detect the environment in which the tobacco leaves are located within the sampling space 17 to obtain environmental data of the tobacco leaves. Thus, through the cooperation of the detection component 20 and the sampling component 10, it is possible to conveniently extend into the tobacco bale to simultaneously detect tobacco leaf data and environmental data of the tobacco leaves, ensuring the stability of the tobacco leaves during the aging process and minimizing the occurrence of adverse problems such as burning of the tobacco bale.

[0030] like Figure 1 and Figure 2 As shown, the detection component 20 includes at least a first detection element 21 and a second detection element 22. Both the first detection element 21 and the second detection element 22 are connected to the sampling space 17 constructed by the sampling component 10, and the tobacco leaf data and the environmental data of the tobacco leaf in the sampling space 17 are obtained through the first detection element 21 and the second detection element 22, respectively.

[0031] Specifically, the first detection component 21 includes a sampling tube 211 and an electronic nose 212. The sampling tube 211 is a flexible tube, and the electronic nose 212 is a portable electronic nose 212. The electronic nose 212 (portable electronic nose 212) is an analytical instrument that simulates the human olfactory system. It detects, analyzes, and identifies volatile odor components through a gas sensor array and a pattern recognition system. During the tobacco aging process, the electronic nose 212 is used to quickly and objectively assess changes in tobacco quality, particularly monitoring mold risk, analyzing differences in volatile components, and determining the degree of aging. Therefore, one end of the sampling tube 211 is connected to the electronic nose 212, and the other end of the sampling tube 211 extends into the sampling space 17 to sample the tobacco leaves within the sampling space 17. Through the cooperation of the sampling tube 211 and the electronic nose 212, volatile organic compounds in the tobacco pack can be quickly detected, and the pattern recognition algorithm built into the electronic nose 212 can effectively determine whether the sampled tobacco leaves are moldy, thereby achieving the detection of tobacco leaves.

[0032] More specifically, the second detection element 22 includes a thermometer, preferably a platinum resistance thermometer. Platinum resistance thermometers offer higher accuracy and stability compared to traditional thermometers, with an accuracy error of no more than ±0.1 degrees Celsius within the range of 0 degrees Celsius to several hundred degrees Celsius. Furthermore, due to the highly stable chemical properties of platinum, it does not exhibit significant temperature drift during long-term operation, thus effectively ensuring the stability and accuracy of the temperature results obtained from tobacco leaf testing.

[0033] like Figure 2 As shown, the sampling assembly 10 includes a first clamp 11 and a second clamp 12, wherein the first clamp 11 and the second clamp 12 are movably connected, and a working space 16 for accommodating the insertion of the detection assembly 20 is formed between the first clamp 11 and the second clamp 12. The working space 16 is connected to the sampling space 17. Therefore, when the first detection element 21 and / or the second detection element 22 are inserted into the working space 16, the first detection element 21 and / or the second detection element 22 can extend from the working space 16 into the sampling space 17 to realize the detection of tobacco leaves and the environment in the sampling space 17.

[0034] In an optional embodiment, the first clamp 11 has at least a first mounting portion 111 on its first end, and the second end of the first clamp 11 is a first handle 113. The second clamp 12 has at least a second mounting portion 121 on its first end, and the second end of the second clamp 12 is a second handle 123. The first mounting portion 111 and the second mounting portion 121 engage to form a first mounting position 14, and the first mounting position 14 is used to connect the first detection element 21.

[0035] In an optional embodiment, the first end of the first clamp 11 is further provided with a third mounting portion, and the first end of the second clamp 12 is further provided with a fourth mounting portion 122. The third mounting portion and the fourth mounting portion 122 are engaged to form a second mounting position 15, which is used to connect the second detection element 22.

[0036] Therefore, in this embodiment, the first detection element 21 and the second detection element 22 are respectively connected to the first mounting position 14 and the second mounting position 15. The first mounting position 14 and the second mounting position 15 are jointly formed by the first clamp 11 and the second clamp 12. The first mounting position 14 and the second mounting position 15 formed can fix the first detection element 21 and the second detection element 22 to ensure the stability of the first detection element 21 and the second detection element 22 during detection.

[0037] In addition, when the first detection element 21 and / or the second detection element 22 are respectively connected to the first mounting position 14 and the second mounting position 15, the following explanation will be based on the example of the first detection element 21 being connected to the first mounting position 14.

[0038] First, the first mounting position 14 is formed by the mating connection of the first mounting part 111 and the second mounting part 121. Therefore, when the first mounting part 111 on the first clamp 11 and the second mounting part 121 on the second clamp 12 are inserted into the cigarette pack, the first mounting part 111 and the second mounting part 121 are in a mating state. After the first mounting part 111 and the second mounting part 121 are inserted into the cigarette pack, the first mounting part 111 and the second mounting part 121 can be partially opened, and then the first detection element 21 is inserted into the first mounting part 111. Subsequently, the first mounting part 111 and the second mounting part 121 are brought closer to each other so that the first mounting part 111 and the second mounting part 121 are mated. At this time, the first detection element 21 is fixed in the first mounting position 14 formed by the first mounting part 111 and the second mounting part 121, thereby fixing the first detection element 21. Similarly, the second detection element 22 can be fixed in the same way.

[0039] In an optional embodiment, the first mounting position 14 and the second mounting position 15 may also be directly formed on the first mounting portion 111 or the second mounting portion 121. For example, the first mounting position 14 may be formed on the first mounting portion 111 or the second mounting portion 121. Similarly, the second mounting position 15 may be formed on the first mounting portion 111 or the second mounting portion 121. In this case, the first detection element 21 corresponding to the first mounting position 14 can be directly connected to the first mounting position 14 formed on the first mounting portion 111 or the second mounting portion 121; the second detection element 22 corresponding to the second mounting position 15 can also be directly connected to the second mounting position 15 formed on the first mounting portion 111 or the second mounting portion 121. It should be noted that the first clamp 11 and the second clamp 12 are not limited to only having the first mounting position 14 and the second mounting position 15; a third mounting position, a fourth mounting position, etc., may also be provided to accommodate multiple detection elements.

[0040] In addition, when the first detection element 21 is placed in the corresponding first mounting position 14, or the second detection element 22 is placed in the corresponding second mounting position 15, the detection ends of the first detection element 21 and the second detection element 22 can be fixed in the corresponding first mounting position 14 and the second mounting position 15 in advance, without having to wait for the first clamp 11 and the second clamp 12 to be inserted into the cigarette pack before installing and fixing the first detection element 21 and the second detection element 22.

[0041] In an optional embodiment, both the first clamp 11 and the second clamp 12 are sheet-like structures. In this embodiment, the first clamp 11 and the second clamp 12 are configured as two metal plates of the same size, with their surfaces facing each other. A rotating member 13 is provided between the two metal plates. The middle surface of the first clamp 11 is hinged to the first end of the rotating member 13, and the middle surface of the second clamp 12, corresponding to the hinge point of the first clamp 11, is hinged to the second end of the rotating member 13. For example, the rotating member 13 can be connected to the first clamp 11 and the second clamp 12 by a rotating pin, a hinge seat, or other structure, so that the first clamp 11 and the second clamp 12 can rotate independently on both ends of the rotating member 13, and the two ends of the rotating member 13 that are hinged to the first clamp 11 and the second clamp 12 are opposite to each other.

[0042] Therefore, when the first clamp 11 and the second clamp 12 perform the cigarette pack insertion operation, the first clamp 11 rotates towards the second end of the second clamp 12, and similarly, the second clamp 12 can rotate towards the first end of the first clamp 11. That is, the first end of the first clamp 11 and the first end of the second clamp 12 can approach each other. When the first end of the first clamp 11 and the first end of the second clamp 12 abut against each other, the first mounting part 111 provided on the first clamp 11 and the second mounting part 121 provided on the second clamp 12 engage to form the first mounting position 14, and the second mounting position 15 is formed in the same way. Therefore, both the first clamp 11 and the second clamp 12 are tilted relative to the horizontal plane. When they are in the engaged state, the distance between the first end of the first clamp 11 and the first end of the second clamp 12 is smaller than the distance between their second ends. The first ends of the first clamp 11 and the second clamp 12 are close to each other, which allows for a smaller cutting area between them and the tobacco leaves when they are inserted. This makes it easier for the first clamp 11 and the second clamp 12 to penetrate into the tobacco pack to inspect the tobacco leaves.

[0043] Furthermore, the first clamp 11 and the second clamp 12 are configured as sheet-like structures, and the space formed between the first clamp 11 and the second clamp 12 is the working space 16. After the first clamp 11 and the second clamp 12 are inserted into the cigarette pack, if the second ends of the first clamp 11 and the second clamp 12 are squeezed relative to each other, the first ends of the first clamp 11 and the second clamp 12 will be released from the engaged state and opened. At this time, the first clamp 11 and the second clamp 12 can be opened at the sampling point of the cigarette pack, and the space opened up inside the cigarette pack is the sampling space 17.

[0044] Furthermore, the sheet-like structure provided by the first clamp 11 and the second clamp 12 can also protect the detection component 20 located between the first clamp 11 and the second clamp 12 when it is inserted into the tobacco pack, so as to prevent the tobacco leaves in the tobacco pack from being squeezed into the working space 16, thereby affecting the normal detection of the tobacco leaves by the detection component 20.

[0045] In an optional embodiment, the first mounting portion 111 and the second mounting portion 121 are respectively provided on the first clamp 11 and the second clamp 12, and since both the first clamp 11 and the second clamp 12 are configured as sheet-like structures, in order to adapt to the shapes of the first clamp 11 and the second clamp 12, in this embodiment, the first mounting portion 111 and the third mounting portion provided on the first clamp 11 can be arranged along the width direction of the first clamp 11, and similarly, the second mounting portion 121 and the fourth mounting portion 122 on the second clamp 12 can be arranged along the width direction of the second clamp 12. It is necessary to ensure that the first mounting portion 111 and the second mounting portion 121 correspond in position when they are engaged, and that the third mounting portion and the fourth mounting portion 122 correspond in position when they are engaged, so as to form the first mounting position 14, the second mounting position 15, etc. If the first mounting position 14, the second mounting position 15, etc., are directly formed on the first mounting portion 111 or the second mounting portion 121, then it is not necessary to maintain the positional correspondence.

[0046] Furthermore, the rotating component 13 also needs to be adapted to the structural style of the first clamp 11 and the second clamp 12. That is, the rotating component 13 also extends along the width direction of the first clamp 11 and the second clamp 12. Since the first clamp 11 and the second clamp 12 need to be inserted into the tobacco pack, after they are fully inserted, the tobacco leaves inside the tobacco pack will exert a large pressure on the first clamp 11 and the second clamp 12. Therefore, in order to avoid the tobacco leaves pressing the first clamp 11 and the second clamp 12, and thus pressing the rotating component 13 and forcing the rotating component 13 to undergo twisting deformation, the strength of the rotating component 13 needs to be set to be able to withstand a certain pressure value, so as to avoid the first clamp 11 and the second clamp 12 from shifting due to the deformation of the rotating component 13.

[0047] In this embodiment, the tobacco bales are typically made by compacting approximately 200 kg of tobacco leaves into a cardboard box and storing them for 1-3 years under specific temperature and humidity conditions. This process is used to age the tobacco leaves, improving their sensory quality, and is a necessary step in tobacco processing. However, during the aging process, the tobacco bales may experience mold growth, burning, or other problems.

[0048] Therefore, the rapid tobacco inspection device described in any of the above embodiments can achieve rapid inspection of tobacco leaves inside tobacco bales. During inspection, the rapid tobacco inspection device, through the cooperation of the detection component 20 and the sampling component 10, extends into the tobacco bale for inspection. The sampling component 10 of the rapid tobacco inspection device includes a first clamp 11 and a second clamp 12. The insertion ends of the first clamp 11 and the second clamp 12 are inclined relative to each other to achieve mutual proximity. The first ends that are close to each other can be easily inserted into the tobacco bale, so that the first ends reach the sampling point of the tobacco bale, and a sampling space 17 is constructed at the sampling point of the tobacco bale. Then, the first detection element 21 and the second detection element 22 are extended into the sampling space 17 to perform sampling and inspection, so as to obtain tobacco leaf data and environmental data at the sampling point of the tobacco bale. Among them, the tobacco leaf data measured by the first detection element 21 is input into the electronic nose 212 through the sampling tube 211. The electronic nose 212 can quickly detect mold on the sampled tobacco leaves. The second detection component 22 is a thermometer, which can be used to quickly detect the temperature at the sampling point inside the tobacco pack to determine whether the temperature exceeds the standard. Therefore, this rapid tobacco leaf testing device can quickly detect the tobacco leaves and their internal environment inside the tobacco pack, enabling the detection of mold and temperature within minutes, with accurate and fast results.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
