Description

Technical Field

[0001] This invention relates to the field of cigarette quality monitoring technology, and more particularly to a device for monitoring the expansion and contraction of cigar cigarettes. Background Technology

[0002] Whole-leaf cigars are tobacco products made from whole tobacco leaves as wrappers, binders, and fillers. Throughout their entire life cycle from production to consumption, cigars undergo three key stages: inner shaping, pressure relief and rebound, aging and storage, and lighting and smoking. During each stage, the cigar expands or contracts, and its internal stress changes accordingly.

[0003] The shaping, turning, and depressurization stages involve placing the rolled cigar blank into a mold and applying pressure to shape it. The cigar blank undergoes several processes: pressing, holding pressure, depressurization, and rebound. After demolding, deformation is visually inspected manually, making it impossible to accurately measure the rebound amount. Aging storage involves aging cigars in aging rooms or warehouses for months to years. During this time, the cigars will absorb moisture and expand or lose moisture and shrink. Offline sampling using calipers or laser diameter meters cannot continuously track the expansion and contraction of the same cigar. When lit and smoked, the temperature of the cigar's combustion cone reaches as high as 900℃, causing thermal expansion, internal pressure fluctuations, and structural collapse. Existing equipment cannot measure the expansion and contraction of the cigar during combustion. Current measuring devices cannot achieve non-destructive, long-term, continuous monitoring of the expansion and contraction of cigars. Summary of the Invention

For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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 communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] Figure 1 This is a schematic diagram of a cigar expansion and contraction monitoring device provided in an embodiment of the present invention. This embodiment is applicable to non-destructive continuous monitoring of the expansion and contraction state of cigars from the production stage to the consumption stage. Figure 1As shown, the cigar expansion and contraction monitoring device provided in this embodiment of the invention includes a stress sensing module 10 and a control processing module 20; the stress sensing module 10 is used to collect stress change signals of the cigar 30; the control processing module 20 is electrically connected to the stress sensing module 10 and is used to receive stress change signals and determine the expansion and contraction state of the cigar 30 based on the stress change signals.

[0022] In this embodiment, the cigar expansion and contraction monitoring device includes a stress sensing module 10 and a control processing module 20. The stress sensing module 10 can be understood as a sensing component capable of real-time acquisition of stress inside or on the surface of the measured structure, converting mechanical deformation into a readable electrical signal, and then outputting it. Exemplarily, the stress sensing module 10 includes, but is not limited to, a flexible stress sensor; this embodiment of the invention does not impose any limitations on this. The control processing module 20 can be understood as a functional module capable of receiving instructions, acquiring signals, performing calculations, and outputting control signals to drive actuators to complete preset actions. The control processing module 20 includes, but is not limited to, a programmable logic controller (PLC) and a computer; this embodiment of the invention does not impose any limitations on this.

[0023] Specifically, the stress sensing module 10 is disposed on the surface or inside the cigar stick 30 to collect stress change signals of the cigar stick 30 under different monitoring scenarios. The sampling frequency of the stress sensing module 10 can be adjusted according to the actual monitoring environment. The control processing module 20 is electrically connected to the stress sensing module 10. After receiving the stress change signal, the control processing module 20 converts and calculates the stress change signal, and determines the expansion and contraction state of the cigar stick 30 based on the calculation result. The expansion and contraction state of the cigar stick 30 can be understood as the expansion deformation and contraction deformation of the cigar stick 30.

[0024] To avoid the impact of temperature drift and zero-point drift generated by the stress sensing module 10 during long-term continuous monitoring of the stress change signal of the cigar 30 on the accuracy of stress change signal acquisition, the control processing module 20 can be equipped with a temperature compensation algorithm and a zero-point drift correction algorithm. The received stress change signal is then compensated for temperature and corrected for zero-point drift before calculation to determine the expansion and contraction state of the cigar 30. This ensures the accuracy of monitoring the expansion and contraction state of the cigar 30 and reduces the problem of inaccurate stress change signals caused by zero-point drift and temperature drift during long-term monitoring, thus preventing the accurate acquisition of the expansion and contraction state of the cigar 30.

[0025] For example, in the initial stable state, the cigar 30 calibrates the signal output by the stress sensing module 10 to a reference signal. Using this signal as a reference, when the value of the stress change signal received by the control processing module is greater than the reference signal, i.e., the cigar 30 has generated tensile stress, the state of the cigar 30 is determined to be a contracted state. When the value of the stress change signal received by the control processing module 20 is less than the reference signal, i.e., the cigar 30 has generated compressive stress, the state of the cigar 30 is determined to be an expanded state.

[0026] The cigar expansion and contraction monitoring device provided in this invention uses a stress sensing module 10 to collect stress change signals from the cigar 30. A control processing module 20 is electrically connected to the stress sensing module 10 to receive the stress change signals and determine the expansion and contraction state of the cigar 30 based on these signals. This configuration allows for long-term, non-destructive, continuous monitoring of the stress and expansion / contraction state of the cigar 30 by the stress sensing module 10. It is adaptable to various scenarios from production to consumption, ensuring the quality of the cigar 30 at each stage without relying on manual monitoring, thus improving monitoring efficiency and reducing monitoring errors. This solves the problems of existing devices being unable to sense stress and unable to conduct long-term continuous monitoring when monitoring the expansion and contraction state of cigars 30.

[0027] Optional, you can continue to refer to Figure 1 The stress sensing module 10 includes a first stress sensing element 11 and a second stress sensing element 12. The first stress sensing element 11 and the second stress sensing element 12 are attached to the surface of the cigar stick 30 along the circumferential direction. The first stress sensing element 11 is used to collect a first stress change signal of the cigar stick 30 in a first monitoring environment, and the second stress sensing element 12 is used to collect a second stress change signal of the cigar stick 30 in a second monitoring environment. The temperature of the first monitoring environment is different from that of the second monitoring environment, and / or the humidity of the first monitoring environment is different from that of the second monitoring environment. The control processing module 20 is used to determine the expansion and contraction state of the cigar stick 30 under the corresponding temperature and humidity in the first monitoring environment based on the first stress change signal, and to determine the expansion and contraction state of the cigar stick 30 under the corresponding temperature and humidity in the second monitoring environment based on the second stress change signal.

[0028] In this embodiment, the stress sensing module 10 includes a first stress sensing sheet 11 and a second stress sensing sheet 12. The first stress sensing sheet 11 and the second stress sensing sheet 12 can be understood as two core sensing elements in the stress sensing module 10, made of different materials and suitable for different scenarios, based on the metal resistance strain effect and capable of converting the mechanical deformation of the structure under test into resistance changes. Exemplarily, the first stress sensing sheet 11 and the second stress sensing sheet 12 may include, but are not limited to, resistive or fiber Bragg grating stress sheets; this embodiment of the invention does not impose any limitations on this.

[0029] Specifically, both the first stress sensing plate 11 and the second stress sensing plate 12 have flexible substrates that can be tightly attached to the wrapper or binder surface of the cigar stick 30, and are both arranged along the circumferential direction of the cigar stick 30. The first stress sensing plate 11 is used to monitor the first stress change signal on the surface of the cigar stick 30 in a first monitoring environment. The first monitoring environment can be the temperature and humidity environment during the shaping of the cigar stick 30, or the temperature and humidity environment during the aging and storage process of the cigar stick 30 after rolling. This embodiment of the invention does not limit this. The first stress sensing plate 11 transmits the first stress change signal to the control processing module 20. The control processing module 20 receives the first stress change signal and determines the expansion and contraction state of the cigar stick 30 under the corresponding temperature and humidity in the first monitoring environment based on the first stress change signal.

[0030] The second stress sensing element 12 is used to monitor the second stress change signal on the surface of the cigar stick 30 in a second monitoring environment. The second monitoring environment can be the temperature and humidity environment of the cigar stick 30 after it is lit and smoked; this embodiment of the invention is not limited to this. The second stress sensing element 12 transmits the second stress change signal to the control processing module 20. The control processing module 20 receives the second stress change signal and determines the expansion and contraction state of the cigar stick 30 under the corresponding temperature and humidity in the second monitoring environment based on the second stress change signal.

[0031] The temperature of the first monitoring environment differs from the temperature of the second monitoring environment, or the humidity of the first monitoring environment differs from the humidity of the second monitoring environment, or both the temperature and humidity of the first monitoring environment differ from the humidity of the second monitoring environment. For example, the temperature of the first monitoring environment may be lower than the temperature of the second monitoring environment, and the humidity of the first monitoring environment may be higher than the humidity of the second monitoring environment; this embodiment of the invention does not impose any limitations on this.

[0032] For example, the first stress sensing element 11 can be a room-temperature stress sensing element, which can be made of polyimide substrate and has an applicable temperature range of -40℃ to 120℃, suitable for room-temperature scenarios such as aging storage and end-body shaping of cigar sticks 30. The second stress sensing element 12 can be a high-temperature stress sensing element, which can be made of ceramic fiber substrate and has a heat-reflective coating, and can be used in scenarios where the instantaneous temperature can reach 400℃, suitable for lighting and smoking scenarios of cigar sticks 30. The first stress sensing element 11 is used to monitor the first stress change signal of cigar sticks 30 in aging storage and end-body shaping scenarios and transmit the first stress change signal to the control processing module 20, and the second stress sensing element 12 is used to monitor the second stress change signal of cigar sticks 30 in lighting and smoking scenarios and transmit the second stress change signal to the control processing module 20. The control processing module 20 determines the expansion and contraction state of the cigar stick 30 in the aging and storage scenario and the endoderm shaping scenario based on the first stress change signal, and determines the expansion and contraction state of the cigar stick 30 in the lighting and smoking scenario based on the second stress change signal.

[0033] The cigar expansion and contraction monitoring device provided in this embodiment of the invention uses a first stress sensing plate 11 and a second stress sensing plate 12 attached to the surface of the cigar 30 along its circumference. The first stress sensing plate 11 collects a first stress change signal of the cigar 30 in a first monitoring environment, and the second stress sensing plate 12 collects a second stress change signal of the cigar 30 in a second monitoring environment. The control processing module 20 determines the expansion and contraction state of the cigar 30 under the corresponding temperature and humidity in the first monitoring environment based on the first stress change signal, and determines the expansion and contraction state of the cigar 30 under the corresponding temperature and humidity in the second monitoring environment based on the second stress change signal. This configuration allows for long-term continuous monitoring of the expansion and contraction state of the cigar 30 in different scenarios without repeatedly removing the cigar 30, by using different stress sensing plates to meet the temperature and humidity requirements of different scenarios. This improves the efficiency and applicability of monitoring the expansion and contraction state of cigar sticks 30, making it suitable for various scenarios from production to consumption of cigar sticks 30, and solving the problem that existing monitoring devices cannot cover the expansion state monitoring of cigar sticks 30 in multiple scenarios.

[0034] Figure 2 This is a schematic diagram of another cigar expansion and contraction monitoring device provided in an embodiment of the present invention, as shown below. Figure 2As shown, the stress sensing module 10 includes a third stress sensing element 13; the third stress sensing element 13 is embedded in the inner core of the cigar stick 30 along the circumferential direction of the cigar stick 30, and is used to collect the third stress change signal of the cigar stick 30 in the third monitoring environment; the control processing module 20 is used to determine the internal expansion and contraction state of the cigar stick 30 in the third monitoring environment based on the third stress change signal.

[0035] In this embodiment, the stress sensing module 10 includes a third stress sensing element 13. The third stress sensing element 13 can be understood as a core sensing element in the stress sensing module 10, based on the metal resistance strain effect, capable of converting the mechanical deformation of the structure under test into a resistance change. Exemplarily, the third stress sensing element 13 includes, but is not limited to, resistive or fiber Bragg grating stress elements; this embodiment of the invention does not impose any limitations on this.

[0036] Specifically, the third stress sensing element 13 has a flexible substrate and is embedded in the inner core of the cigar stick 30 along the circumference of the cigar stick 30. It is used to collect the third stress change signal of the cigar stick 30 in a third monitoring environment. The third monitoring environment can be the environment inside the inner core of the cigar stick 30, and the third stress change signal is the stress change signal of the inner core of the cigar stick 30 sensed by the third stress sensing element 13. The third stress sensing element 13 transmits the collected third stress change signal to the control processing module 20, which determines the expansion and contraction state of the cigar stick 30 inside the third monitoring environment based on the third stress change signal.

[0037] For example, the third stress sensing sheet 13 may be a miniature embedded stress sheet with a silicone rubber substrate. The size of the third stress sensing sheet 13 is less than or equal to 2mm × 3mm, and this embodiment of the invention does not impose any limitation on it.

[0038] The cigar expansion and contraction monitoring device provided in this invention embeds a third stress sensing plate 13 along the circumference of the cigar 30 inside the cigar body, and collects a third stress change signal of the cigar 30 in a third monitoring environment. The control processing module 20 determines the internal expansion and contraction state of the cigar 30 in the third monitoring environment based on the third stress change signal. This setup ensures that the monitoring results closely match the actual deformation inside the cigar 30, reduces interference from the wrapper layer of the cigar 30, and realizes the monitoring of the internal expansion and contraction state of the cigar 30, improving the monitoring accuracy and stability. It solves the problem that existing monitoring devices cannot monitor the rebound state of the cigar body and reduces the influence of the wrapper layer's buffering on the monitoring of the internal expansion and contraction state of the cigar 30.

[0039] Optional, you can continue to refer to Figure 1 and Figure 2 The stress sensing module 10 also includes a first stress sensing sheet 11 and a second stress sensing sheet 12, which are attached to the surface of the cigar stick 30 along the circumferential direction of the cigar stick 30; the thickness of the third stress sensing sheet 13 is less than the thickness of the first stress sensing sheet 11 and the second stress sensing sheet 12.

[0040] Specifically, since the first stress sensing piece 11 and the second stress sensing piece 12 are both attached to the surface of the cigar stick 30 along the circumferential direction, while the third stress sensing piece 13 is embedded in the inner core of the cigar stick 30 along the circumferential direction, the installation space of the third stress sensing piece 13 is smaller than that of the first stress sensing piece 11 and the second stress sensing piece 12. Therefore, the thickness of the third stress sensing piece 13 needs to be smaller than that of the first stress sensing piece 11 and the second stress sensing piece 12, so that the third stress sensing piece 13 can be smoothly installed in the inner core of the cigar stick 30 without causing compression damage to the cigar stick 30.

[0041] Furthermore, since the first stress sensing element 11 is suitable for monitoring environments with relatively low temperatures and has strong deformation tracking of thin substrates, resulting in higher sensitivity for stress change signal measurement, the first stress sensing element 11 can completely transmit the stress change signals of the cigar body and wrapper of the cigar stick 30 without needing to be thickened. The second stress sensing element 12, on the other hand, is suitable for monitoring environments with relatively high temperatures. The high-temperature resistant material used is inherently brittle and has poor tensile toughness. If the thickness is too thin, it is prone to breakage and delamination. Additionally, a heat-reflective coating is required for insulation. Therefore, the thickness of the first stress sensing element 11 is less than the thickness of the second stress sensing element 12.

[0042] For example, the thickness of the third stress sensing sheet 13 can be in the range of 0.05mm-0.10mm, the thickness of the first stress sensing sheet 11 can be in the range of 0.10mm-0.15mm, and the thickness of the second stress sensing sheet 12 can be in the range of 0.15mm-0.25mm. This embodiment of the invention does not limit the thickness of the third stress sensing sheet 13.

[0043] The cigar expansion and contraction monitoring device provided in this embodiment of the invention, based on the placement of the first stress sensing plate 11, the second stress sensing plate 12, and the third stress sensing plate 13, has a thickness of the third stress sensing plate 13 that is less than the thickness of the first stress sensing plate 11 and the second stress sensing plate 12. The thin third stress sensing plate 13 is highly flexible and occupies little space, reducing the compression and damage to the tobacco inside the cigar 30 while accurately collecting stress change signals within the cigar 30, thus improving the accuracy of stress change signal acquisition. This solves the problem that stress sensing plates of uniform thickness cannot simultaneously adapt to the confined space within the cigar 30 and the complex external environment, and reduces the monitoring distortion caused by damage to the cigar 30 due to thicker stress sensing plates embedded inside.

[0044] Figure 3 This is a schematic diagram of another cigar expansion and contraction monitoring device provided in an embodiment of the present invention. Figure 4 This is a schematic diagram of the connection structure of another cigar expansion and contraction monitoring device provided in an embodiment of the present invention. Figure 3 and Figure 4 As shown, the cigar expansion and contraction monitoring device also includes a temperature and humidity adjustment module 40; the temperature and humidity adjustment module 40 is electrically connected to the control processing module 20, and the temperature and humidity adjustment module 40 is used to adjust the temperature and humidity of the monitoring environment where the cigar 30 is located according to the temperature and humidity adjustment command issued by the control processing module 20, so as to form a first monitoring environment or a second monitoring environment.

[0045] In this embodiment, the cigar expansion and contraction monitoring device further includes a temperature and humidity control module 40. The temperature and humidity control module 40 can be understood as a functional module capable of receiving control signals and outputting control actions based on these signals to regulate the ambient temperature and relative humidity. For example, the temperature and humidity control module 40 may include, but is not limited to, an integrated temperature and humidity control unit; this embodiment of the invention does not impose any limitations on this.

[0046] Specifically, the temperature and humidity control module 40 is electrically connected to the control processing module 20. When it is necessary to monitor the expansion and contraction of the cigar stick 30 in the first monitoring environment, the control processing module 20 sends a temperature and humidity control command to the temperature and humidity control module 40. The temperature and humidity control module 40 receives the temperature and humidity control command and adjusts the temperature and humidity of the monitoring environment where the cigar stick 30 is located according to the command, so that the temperature and humidity of the monitoring environment where the cigar stick 30 is located reach the temperature and humidity required by the first monitoring environment.

[0047] When it is necessary to monitor the expansion and contraction of the cigar stick 30 in the second monitoring environment, the control processing module 20 sends a temperature and humidity adjustment command to the temperature and humidity adjustment module 40. The temperature and humidity adjustment module 40 receives the temperature and humidity adjustment command and adjusts the temperature and humidity of the monitoring environment where the cigar stick 30 is located according to the command, so that the temperature and humidity of the monitoring environment where the cigar stick 30 is located reach the temperature and humidity required by the second monitoring environment.

[0048] For example, when the temperature of the first monitoring environment is -40℃ to 120℃ and the relative humidity is 60% to 75%RH, while the temperature of the current monitoring environment where the cigar stick 30 is located is 150℃ and the relative humidity is 30%RH, it is necessary to monitor the expansion and contraction state of the cigar stick 30 in the first monitoring environment. The control processing module 20 controls the temperature and humidity adjustment module 40 to cool and humidify, so as to control the temperature and humidity of the current monitoring environment to reach the temperature and humidity of the first monitoring environment.

[0049] The cigar expansion and contraction monitoring device provided in this embodiment of the invention, by electrically connecting a temperature and humidity adjustment module 40 to a control processing module 20, allows the temperature and humidity of the monitoring environment containing the cigar 30 to be adjusted according to temperature and humidity adjustment commands issued by the control processing module 20, thereby creating either a first monitoring environment or a second monitoring environment. This configuration enables automated setting and switching between two monitoring environments, while simultaneously providing precise temperature and humidity control, reducing measurement errors caused by environmental fluctuations, eliminating the need for manual intervention, and improving monitoring efficiency. It solves the problems of low monitoring efficiency caused by the need for manual adjustment and switching of the monitoring environment, and inaccurate monitoring of the expansion and contraction state of the cigar 30 due to inaccurate manual environmental control.

[0050] Optional, you can continue to refer to Figure 3 and Figure 4 The cigar expansion and contraction monitoring device also includes a suction adjustment module 50; the suction adjustment module 50 is electrically connected to the control processing module 20 and is used to ignite the cigar 30 according to the suction simulation command issued by the control processing module 20 and to suck the cigar 30 at a preset frequency to form a third monitoring environment.

[0051] In this embodiment, the cigar expansion and contraction monitoring device further includes a draw adjustment module 50. The draw adjustment module 50 can be understood as an integrated execution component capable of simulating the actual drawing action of a cigar, and includes an ignition unit and a draw adjustment unit.

[0052] Specifically, the suction adjustment module 50 is electrically connected to the control processing module 20. When it is necessary to monitor the expansion and contraction state of the cigar 30 in a third monitoring environment, the control processing module 20 sends a suction simulation command to the suction adjustment module 50. The suction adjustment module 50 receives the suction simulation command and ignites the combustion cone of the cigar 30 according to the command, and then draws the cigar 30 at a preset frequency to simulate the process of the cigar 30 being actually drawn, thus forming a third monitoring environment. The third stress sensing element 13 then monitors the stress change signal of the cigar 30 in the third monitoring environment to obtain the expansion and contraction state of the cigar 30 in the third monitoring environment.

[0053] For example, when it is necessary to monitor the expansion and contraction state of the cigar stick 30 in a third monitoring environment, the control processing module 20 controls the suction adjustment module 50 to ignite the combustion cone of the cigar stick and suck the cigar stick 30 at a frequency of 10s-60s, with each suck lasting 1s-3s, to simulate the process of the cigar stick 30 being actually sucked.

[0054] In addition, the expansion and contraction monitoring device of the cigar stick 30 also includes a flow guiding module 51. The flow guiding module 51 is set in the monitoring environment of the cigar stick 30. When monitoring the third stress change signal of the cigar stick 30 in the third monitoring environment, it is used to extract the smoke generated by the cigar stick 30 during combustion, so as to avoid the problem of inaccurate acquisition of the third stress change signal caused by the interference of the smoke to the monitoring environment.

[0055] The cigar expansion and contraction monitoring device provided in this embodiment of the invention, by electrically connecting the suction adjustment module 50 and the control processing module 20, ignites the cigar 30 according to the suction simulation command issued by the control processing module 20 and sucks the cigar 30 at a preset frequency to form a third monitoring environment. This setup achieves automatic control and simulation of the cigar sucking process, the monitoring environment is reproducible, and continuous monitoring of the expansion and contraction state of the cigar 30 is realized. Furthermore, the suction simulation parameters are precisely adjustable, improving the accuracy of monitoring the expansion and contraction state of the cigar 30 and reducing the cumbersome and safety hazards of manual sucking operations.

[0056] Optional, you can continue to refer to Figure 3 and Figure 4 The cigar expansion and contraction monitoring device also includes a shaping and pressure relief module 60; the shaping and pressure relief module 60 is used to apply pressure to the inner body of the cigar 30 to shape the cigar 30.

[0057] In this embodiment, the cigar expansion and contraction monitoring device further includes a shaping and pressure relief module 60. The shaping and pressure relief module 60 can be understood as an execution component capable of receiving control commands, applying constant molding pressure to the inner preform of the cigar 30, and slowly releasing pressure according to a preset sequence. Exemplarily, the shaping and pressure relief module 60 includes, but is not limited to, a semi-cylindrical shaping fixture capable of rapid pressure relief; this embodiment of the invention does not impose any limitations on this.

[0058] Specifically, the shaping and depressurization module 60 applies uniform radial pressure to the inner core of the cigar stick 30 to shape it, and can quickly depressurize the cigar stick 30 after shaping to trigger the rebound of the inner core. The first stress sensing plate 11 can collect the first stress change signal of the cigar stick 30 during the rebound process, and the control processing module 20 obtains the expansion and contraction state of the cigar stick 30 in the inner core shaping scenario based on the first stress change signal.

[0059] For example, after the cigar stick 30 is shaped, the shaping pressure relief module 60 can release the shaping pressure within 0.5 seconds, triggering the rebound of the inner core of the cigar stick 30.

[0060] The cigar expansion and contraction monitoring device provided in this embodiment of the invention applies pressure to the inner core of the cigar 30 by setting a shaping and pressure-relieving module 60, thus shaping the cigar 30. The inner core of the cigar 30 is subjected to uniform circumferential pressure, completing the shaping process while avoiding damage caused by localized compression. Furthermore, rapid pressure relief instantly removes the external constraint force on the cigar 30, allowing the first stress sensing element 11 to capture the first stress change signal generated by the instantaneous rebound of the inner core after demolding. Since the environmental parameters fluctuate almost completely during rapid pressure relief, the first stress change signal originates solely from the inner core's rebound, improving the signal-to-noise ratio of the first stress change signal and ensuring that the control processing module 20 accurately identifies the expansion and contraction state of the cigar 30 when pressure relief is triggered. This solves the problem that existing monitoring devices cannot capture the expansion and contraction state of the cigar 30 at the instant the shaping pressure is completely released.

[0061] Optional, you can continue to refer to Figure 3 and Figure 4 The cigar expansion and contraction monitoring device also includes an early warning module 70; the control processing module 20 is electrically connected to the early warning module 70 and is used to control the early warning module 70 to issue an early warning message when the stress change signal is greater than the preset stress threshold.

[0062] In this embodiment, the cigar expansion and contraction monitoring device further includes an early warning module 70. The early warning module 70 can be understood as an alarm component capable of receiving signals and outputting audible and visual alarm signals and digital prompts, etc., based on the signals. Exemplarily, the early warning module 70 includes, but is not limited to, indicator lights and buzzers; this embodiment of the invention does not impose limitations on these.

[0063] Specifically, the control processing module 20 is electrically connected to the early warning module 70. The control processing module 20 has a preset stress threshold. It receives stress change signals and compares them with the preset stress threshold. When the stress change signal exceeds the preset stress threshold, it indicates that the circumferential tensile stress currently borne by the cigar stick 30 exceeds its tensile strength, posing a risk of the cigar wrapper of the cigar stick 30 cracking. At this time, the control processing module 20 sends a signal to the early warning module 70, which then issues an early warning message. This early warning message can indicate that the cigar wrapper of the cigar stick 30 has cracked.

[0064] For example, the preset stress threshold can be set to 80% of the tensile strength of the cigar 30 determined by pre-measurement; this embodiment of the invention does not limit this. The stress sensing module 10 obtains the stress change signal currently borne by the wrapper of the cigar 30 in real time and transmits it to the control processing module 20. When the control processing module 20 determines that the received stress change signal is greater than 80% of the tensile strength of the cigar 30, it controls the early warning module 70 to issue an early warning to prevent damage to the cigar 30.

[0065] The cigar wrapper expansion and contraction monitoring device provided in this embodiment of the invention, through the electrical connection between the control processing module 20 and the early warning module 70, controls the early warning module 70 to issue an early warning message when the stress change signal exceeds a preset stress threshold. This configuration enables real-time online monitoring of the stress on the wrapper of the cigar 30, providing early warning before cracking or damage occurs. This allows staff to adjust the temperature and humidity of the aging storage or take protective measures to prevent damage and ensure the quality of the cigar 30. It solves the problem of low yield of cigars 30 due to damage caused by the lack of early warning.

[0066] To make the monitoring of the expansion and contraction state of the cigar stick 30 more accurate, this embodiment of the invention also includes an auxiliary measurement module for assisting in the measurement of the contour and position information of the cigar stick 30.

[0067] Optional, you can continue to refer to Figure 3 and Figure 4The expansion and contraction monitoring device for the cigar stick 30 also includes a circumference measurement module 80; the circumference measurement module 80 moves along the axial direction of the cigar stick 30 to measure multiple circumference information of the cigar stick 30 at different positions in the axial direction; the control processing module 20 is electrically connected to the circumference measurement module 30 to receive multiple circumference information and determine the expansion and contraction state of the cigar stick 30 at different positions in the axial direction based on the multiple circumference information.

[0068] In this embodiment, the cigar expansion and contraction monitoring device further includes a perimeter measurement module 80. The perimeter measurement module 80 can be understood as a detection component capable of measuring the perimeter contour of the cigar 30. Exemplarily, the perimeter measurement module 80 includes, but is not limited to, a laser contour sensor; this embodiment of the invention does not impose limitations on this.

[0069] Specifically, the perimeter measurement module 80 can move along the axial direction of the cigar 30 to measure the contour of the cigar 30 in a non-contact manner, acquiring multiple perimeter information of the cigar 30 at different positions along the axial direction in its initial state, as well as multiple perimeter information at different positions along the axial direction in different monitoring environments. The control processing module 20 is electrically connected to the perimeter measurement module 80. The control processing module 20 receives multiple perimeter information and determines the expansion and contraction state of the cigar 30 at different positions along the axial direction based on the variation amplitude of the multiple perimeter information. This is cross-validated with the stress change signal of the cigar 30 obtained by the stress sensing module 10 to determine the expansion and contraction state of the cigar 30, ensuring the accuracy of monitoring the expansion and contraction state of the cigar 30.

[0070] The cigar expansion and contraction monitoring device provided in this embodiment of the invention measures the circumference of the cigar 30 at different positions along its axial direction by moving a circumference measurement module 80 along the axial direction. A control processing module 20 is electrically connected to the circumference measurement module 80, receives the multiple circumference data, and determines the expansion and contraction state of the cigar 30 at different positions along the axial direction based on the multiple circumference data. This configuration achieves dual-dimensional monitoring of geometric deformation and mechanics, improving the monitoring accuracy and reliability of the expansion and contraction state of the cigar 30, and solving the problem of low reliability of measurement results due to the lack of verification of single stress sensing data. Furthermore, the non-contact circumference measurement method avoids squeezing the stress sensing module 10 installed on the cigar 30, does not interfere with the original stress change signal acquisition, and enables synchronous parallel acquisition of mechanical and geometric contour information, thus improving the monitoring efficiency of the expansion and contraction state of the cigar 30.

[0071] Optional, you can continue to refer to Figure 3 and Figure 4The cigar expansion and contraction monitoring device also includes a positioning module 90; the positioning module 90 is used to monitor the burning position information of the cigar 30 when it is smoked; the control processing module 2 is electrically connected to the positioning module 90 and is used to receive the burning position information and determine the monitoring area of ​​the stress sensing module 10 based on the burning position information.

[0072] In this embodiment, the cigar expansion and contraction monitoring device further includes a positioning module 90. The positioning module 90 can be understood as a functional component used to accurately spatially locate various parts of the cigar 30 and output position information. For example, the positioning module 90 includes, but is not limited to, a laser locator, and this embodiment of the invention does not impose any limitations on it.

[0073] Specifically, the control processing module 20 is electrically connected to the positioning module 90. Since the combustion cone of the cigar 30 is ignited and in a burning state when the expansion and contraction state of the cigar 30 is acquired in the third detection environment, the positioning module 90 needs to monitor the burning position information of the cigar 30 during smoking to prevent damage to the stress sensing module 10 which is positioned at the burning location. The positioning module 90 can move along the axial direction of the cigar 30 and monitor the burning position information in real time, transmitting this information to the control processing module 20. The control processing module 20 receives the burning position information and determines the monitoring area of ​​the stress sensing module 10 based on it, ensuring the effectiveness of the monitoring area and preventing high-temperature damage caused by placing the stress sensing module 10 at the burning location of the cigar 30.

[0074] The cigar expansion and contraction monitoring device provided in this invention uses a positioning module 90 to monitor the combustion position information of the cigar 30 during smoking. A control processing module 20, electrically connected to the positioning module 90, receives the combustion position information and determines the monitoring area of ​​the stress sensing module 10 based on this information. This setup dynamically tracks the high-temperature combustion area in a third detection environment, automatically determining the monitoring position of the stress sensing module 10 based on the combustion position. This allows for the acquisition of the expansion and contraction state of the cigar 30 in the third detection environment, ensuring the effectiveness of the stress sensing module 10's monitoring area. It also avoids the impact of high-temperature combustion on the stress sensing module 10's monitoring, improving the accuracy of the cigar 30's expansion and contraction monitoring. Furthermore, it prevents combustion damage to the stress sensing module 10, extending its service life. This solves the problems of inaccurate stress change signal acquisition and damage to the stress sensing module 10 caused by the inability to obtain the combustion position information of the cigar 30.
