Description

Technical Field

[0001] This utility model relates to the field of tobacco production technology, and in particular to a device for detecting the temperature and humidity of tobacco stack layers. Background Technology

[0002] As a crucial raw material for the tobacco industry, the quality of tobacco leaves directly impacts the quality of the finished product. To ensure the quality stability of tobacco leaves during stacking and storage, it is typically necessary to detect and monitor the internal environmental parameters of the tobacco stacks (such as temperature and humidity).

[0003] In existing technologies, a common method is to manually insert a handheld testing device into the interior of a tobacco stack to collect data. However, because the operation relies entirely on manual control, it is difficult to maintain a consistent depth of insertion, leading to inconsistencies between different testing points. This results in significant data dispersion for the same batch of tobacco, making the data unreliable and failing to reflect the overall condition, thus reducing the reliability of the test data. Furthermore, when testing high-stacking tobacco, operators may need to climb to the top of the stack to perform the insertion, increasing labor intensity and posing safety hazards.

[0004] Therefore, there is an urgent need for a layered temperature and humidity detection device for tobacco stacks to solve the above problems. Utility Model Content

[0048] This embodiment provides a device for detecting the temperature and humidity of tobacco stack layers, such as... Figures 1-5 As shown, the tobacco stack layer temperature and humidity detection device includes a height adjustment mechanism 2, a support mechanism 4, a depth adjustment mechanism 1, and a storage mechanism 3. The height adjustment mechanism 2 includes a base 201, a lifting component, and a lifting block 209. The lifting component is located inside the base 201, and the lifting block 209 is connected to the lifting end of the lifting component. The support mechanism 4 is used to support the base 201. The depth adjustment mechanism 1 includes a support block 101, a telescopic component, and a sensing probe 105. The support block 101 is rotatably mounted on the lifting block 209. The telescopic component is located inside the support block 101, and the output end of the telescopic component is equipped with a sensing probe 105. The telescopic component is used to drive the sensing probe 105 to extend or retract. The storage mechanism 3 is located on the lifting block 209 and is used to stop the support block 101 in the working position or to store the support block 101 inside the lifting block 209.

[0049] This layered temperature and humidity detection device for tobacco stacks, through the cooperation of the lifting component and lifting block 209 of the height adjustment mechanism 2, allows the depth adjustment mechanism 1 to move to different heights. The telescopic component in the depth adjustment mechanism 1 drives the induction probe 105 to extend or retract, which can precisely control the depth of the probe inserted into the tobacco stack, ensuring the consistency of the insertion depth of the induction probe 105 into the tobacco stack when detecting different layers, so that the data results can more comprehensively reflect the overall condition of the tobacco stack, thereby ensuring the accuracy and reliability of the detection data. By setting up the storage mechanism 3, the support block 101 and the induction probe 105 can be stored in the lifting block 209 when not in operation, which is convenient for storage and transportation, and can prevent damage to the induction probe 105, thus improving the durability of the detection device. Furthermore, the layered temperature and humidity detection device for tobacco stacks replaces the method of manually climbing to high stacks for detection, significantly reducing labor intensity, avoiding the safety hazards of working at heights, and further improving the safety and convenience of the detection work.

[0050] Optionally, such as Figure 2 As shown, the telescopic assembly includes a fixed plate 103, a slider 107, a motor 106, and a lead screw 104. A first groove 102 is provided along the length of the support block 101. The fixed plate 103 is fixed to one end of the first groove 102 and has a threaded hole. The slider 107 is slidably disposed within the first groove 102. The motor 106 is fixed within the slider 107. One end of the lead screw 104 passes through the threaded hole and connects to the sensing probe 105, while the other end connects to the output shaft of the motor 106. The lead screw 104 is threadedly engaged with the fixed plate 103 through the threaded hole. The motor 106 drives the lead screw 104 to rotate, causing the sensing probe 105 to move precisely along the length of the support block 101, thereby achieving consistency in the insertion depth of the sensing probe 105 into the tobacco stack and improving the accuracy and reliability of the detection results. Simultaneously, the guiding effect of the slider 107 within the first groove 102 ensures smooth and reliable movement of the sensing probe 105.

[0051] Optionally, such as Figure 1 and Figure 3As shown, the storage mechanism 3 includes a first fixed rod 308 and a guide rod 307. A first sliding hole 108 is provided along the length of the support block 101. The first fixed rod 308 is fixedly mounted on the lifting block 209, passing through the first sliding hole 108. The lifting block 209 has a storage space, and a second sliding hole 301 is provided on the side wall of the storage space. A stop portion is provided at the top of the second sliding hole 301. The guide rod 307 is fixed to the support block 101 and slidably connected to the second sliding hole 301. The guide rod 307 extends along... When the second sliding hole 301 slides to the stop part, the first fixing rod 308 and the guide rod 307 cooperate to stop the support block 101 in the working position, which can reliably stop the support block 101 in the working position, thereby ensuring the stability of the support block 101 in the working state; in the non-working state, the support block 101 can be stored in the storage space of the lifting block 209 along the second sliding hole 301, which is convenient for the storage and transportation of the detection device, and can effectively protect the sensing probe 105, improving the safety and durability of the detection device.

[0052] Optionally, such as Figure 3 As shown, the storage mechanism 3 also includes a limiting plate 303, a connecting rod 304, a buffer rod 306, and a buffer spring 305. The bottom of the storage space is provided with a buffer groove 302. The limiting plate 303 is slidably disposed in the buffer groove 302. One end of the connecting rod 304 is fixedly connected to the limiting plate 303, and the other end is fixedly connected to the buffer rod 306. The buffer rod 306 is perpendicular to the connecting rod 304 and is slidably connected to the second sliding hole 301. The buffer spring 305 is sleeved on the connecting rod 304. One end of the buffer spring 305 abuts against the bottom wall of the storage space, and the other end abuts against the buffer rod 306. When the support block 101 is located in the storage space, the buffer spring 305 is used to make the buffer rod 306 elastically contact the support block 101, thereby effectively reducing the impact force of the support block 101 during the storage process and avoiding wear of the support block 101 or damage to the sensing probe 105 due to hard collision.

[0053] Optionally, such as Figure 4 As shown, the lifting assembly includes a worm gear 203, a worm wheel 205, a rotating shaft 206, a gear 207, a rack 208, and a power source. The worm gear 203 is rotatably mounted on the base 201. The worm wheel 205 and the gear 207 are coaxially fixed on the rotating shaft 206, with the worm wheel 205 meshing with the worm gear 203. The rack 208 is fixed to the inner wall of the lifting block 209, meshing with the gear 207. The power source is connected to the worm gear 203 via a transmission structure. This transmission structure allows the power source to drive the worm gear 203 to rotate, achieving smooth lifting of the lifting block 209. It offers advantages such as high transmission efficiency, smooth operation, and reliable positioning. Simultaneously, the worm gear 203-worm wheel 205 transmission has good self-locking properties, effectively preventing the lifting block 209 from accidentally sliding down during testing due to force, ensuring operational safety and testing accuracy.

[0054] Optionally, the power source includes a handle 204, which is fixed to one end of the worm gear 203 extending from the base 201. This structure is simple, reliable, and easy to operate manually. Specifically, the handle 204 includes a disc and a rod. The disc is fixed to one end of the worm gear 203, and the rod is fixed at an eccentric position on the disc. The rod can rotate freely around its own axis, increasing the rotational torque by utilizing the eccentric rod, making the lifting operation more labor-saving. In other embodiments, the power source can be a lifting drive motor 106, which is connected to the worm gear 203 for transmission, thereby improving lifting efficiency.

[0055] Optionally, the height adjustment mechanism 2 also includes multiple sliding rods 210, which are evenly distributed on the bottom of the lifting block 209. One end of each sliding rod 210 is fixedly connected to the lifting block 209, and the other end is slidably connected to the base 201. The sliding rods 210 provide additional guidance and support during the movement of the lifting block 209, allowing it to move smoothly in a predetermined direction, preventing tilting or swaying, and improving the stability and reliability of the lifting action.

[0056] Optionally, such as Figure 5 As shown, the support mechanism 4 includes multiple self-locking telescopic rods 403, which are evenly distributed along the circumference of the base 201. The telescopic end of each self-locking telescopic rod 403 can be supported on the working surface, forming a multi-point support structure. This ensures that the base 201 is placed stably on the working surface, improving the stability of the detection device. It should be noted that the self-locking telescopic rod 403 is a mature support component in this field, and its specific structure will not be described in detail.

[0057] Optionally, the base 201 is provided with multiple storage slots 401, each corresponding to a self-locking telescopic rod 403. A second fixing rod 402 is provided in the storage slot 401, and one end of the self-locking telescopic rod 403 is rotatably connected to its corresponding second fixing rod 402, so that the self-locking telescopic rod 403 extends out of the storage slot 401 to support the base 201, thereby improving the stability of the support. Furthermore, after the test is completed, the self-locking telescopic rod 403 can be stored in the storage slot 401, saving storage space and effectively protecting the self-locking telescopic rod 403, thus improving the portability and durability of the testing device.

[0058] Optionally, a control panel 202 is provided on the base 201. The depth adjustment mechanism 1, the height adjustment mechanism 2, and the support mechanism 4 are all communicatively connected to the control panel 202. Users can centrally operate and adjust each mechanism through the control panel 202, realizing intelligent, convenient, and controllable detection processes, improving operational efficiency, and further enhancing the accuracy and ease of use of detection data. The control panel 202 can be a centralized or distributed controller. For example, the control panel 202 can be a single microcontroller or composed of multiple distributed microcontrollers. The microcontroller can run control programs, thereby driving each mechanism to perform corresponding actions.

[0059] Optionally, the sensing probe 105 can be a temperature and humidity sensor in the prior art, which has the characteristics of being waterproof, dustproof, and having strong anti-interference ability, and is suitable for various complex storage environments.

[0060] The working process of the leaf stack layer temperature and humidity detection device provided in this embodiment is roughly as follows:

[0061] First, before detection, the depth adjustment mechanism 1 slides along the second sliding hole 301 via the guide rod 307, while the first sliding hole 108 inside the support block 101 slides into contact with the first fixed rod 308. When the guide rod 307 slides along the second sliding hole 301 to the top of the stop section, the support block 101 remains horizontal, ensuring that the sensing probe 105 is inserted into the tobacco leaf in a parallel state, achieving accurate layer detection. Furthermore, the user can rotate the self-locking telescopic rod 403 around the second fixed rod 402 to stably support the base 201, preventing the device from collapsing and ensuring safety during the detection process.

[0062] During the testing process, the user operates the motor 106 via the control panel 202, driving the lead screw 104 fixed to the output end to rotate. The lead screw 104 is threadedly engaged with the fixed plate 103, causing the slider 107 to slide smoothly along the first slide groove 102. Simultaneously, the lead screw 104 is fixed to the sensing probe 105, allowing the sensing probe 105 to precisely extend into the interior of the tobacco stack. The temperature and humidity data collected by the sensing probe 105 are transmitted to the control panel 202 via electrical signals, facilitating real-time observation by the user. Historical data can be automatically recorded and retrieved, achieving uniform depth detection for tobacco stacks of different sizes, reducing data dispersion, and improving the reliability of the test results.

[0063] Simultaneously, the user can rotate the worm gear 203 via the operating handle 204. The worm gear 203 meshes with the worm wheel 205, and the worm wheel 205 has a fixed rotating shaft 206 inside, which drives the gear 207 to rotate. The gear 207 meshes with the rack 208, causing the lifting block 209 to rise and fall along the rack 208. The worm gear 203 and worm wheel 205 have a self-locking function to prevent the lifting block 209 from accidentally sliding down. The sliding rod 210 at the bottom of the lifting block 209 provides stable support during the lifting process, enabling the sensing probe 105 to detect tobacco leaves at high positions without requiring the operator to climb, thereby reducing the risk of falls and ensuring operational safety.

[0064] After the test is completed, the guide rod 307 slides back along the second sliding hole 301. When the guide rod 307 contacts the buffer rod 306, the connecting rod 304 and the buffer spring 305 work together to provide buffer for the depth adjustment mechanism 1 to be stored, so that it retracts into the lifting block 209, reducing the space occupied by the equipment, facilitating storage, and preventing the guide rod 307 from directly colliding with the bottom of the second sliding hole 301, thereby avoiding vibration damage to the sensing probe 105 and ensuring the detection accuracy. The limiting plate 303 slides on the outer wall of the buffer groove 302, which can prevent the connecting rod 304 from disengaging when the guide rod 307 is not in contact with the buffer rod 306, further ensuring the safety of the device.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
