Description

Technical Field

[0001] This invention relates to the field of cigarette processing technology, and in particular to a multi-environment tobacco air separation simulation device. Background Technology

[0002] In cigarette manufacturing, tobacco air separation is a crucial step. Its purpose is to separate materials of different weights and shapes using airflow to remove impurities such as stems and fragments, thereby improving the purity and quality of the tobacco. However, during air separation, the high-speed airflow is in full contact with the tobacco for a considerable period, during which the temperature and humidity of the airflow become significant factors affecting the moisture content of the tobacco.

[0003] Since the temperature and humidity of the workshop directly affect the temperature and humidity of the airflow, and the temperature and humidity of the workshop are easily affected by external factors such as season and weather, once the air in the workshop is relatively dry, the moisture on the surface of the tobacco shreds will evaporate more easily; conversely, if the air humidity is too high, the tobacco shreds may absorb moisture. This series of changes will eventually lead to fluctuations in the moisture content of the tobacco shreds, which in turn will affect the moisture stability of the dried tobacco shreds in the subsequent production process.

[0004] Currently, the airflow temperature and humidity of existing tobacco air separation equipment are uncontrollable due to the influence of the workshop environment. Adjusting equipment parameters is time-consuming and data collection is not accurate. Moreover, a large amount of tobacco is consumed in the process of conducting research on the impact of the air separation process on the moisture fluctuation of tobacco, resulting in unnecessary waste.

[0005] Therefore, it is particularly important to develop a simulation device for air separation equipment that offers advantages such as precise control of environmental temperature and humidity, good experimental repeatability, high data accuracy, and high operational efficiency. Compared to conducting related research directly using air separators in the workshop, simulation equipment can more systematically and scientifically reveal the patterns of moisture changes in tobacco during the air separation process, providing strong theoretical support and technical guidance for adjusting and optimizing air separation equipment parameters in actual production processes. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by providing a multi-environment tobacco air separation simulation device. This device can simulate different environmental conditions such as temperature, humidity, and wind speed to perform air separation operations on tobacco, thereby accurately assessing the impact of different environmental factors on the tobacco air separation effect, optimizing the tobacco air separation process, and improving the quality and production efficiency of tobacco products.

[0007] This invention proposes a multi-environment tobacco air separation simulation device, comprising a temperature and humidity control mechanism, a wind speed control mechanism fixedly installed on the temperature and humidity control mechanism, and an air separation simulation mechanism fixedly installed on the temperature and humidity control mechanism. One end of the wind speed control mechanism is connected to the temperature and humidity control mechanism, and the other end is connected to the air separation simulation mechanism. The temperature and humidity control mechanism is used to adjust the temperature and humidity of its internal environment to a set value. The air separation simulation mechanism is loaded with tobacco. The wind speed control mechanism delivers air from inside the temperature and humidity control mechanism to the air separation simulation mechanism and controls the air speed to drive the tobacco to move in the air separation simulation mechanism. During the movement of the tobacco in the air separation simulation mechanism, the air separation simulation mechanism performs air separation on the tobacco.

[0008] Furthermore, the temperature and humidity control mechanism includes a balance chamber and a constant temperature and humidity unit. The constant temperature and humidity unit is connected to the balance chamber and is used to control the temperature and humidity of the balance chamber. The balance chamber is used to adjust and maintain the temperature and humidity of its internal environment in a balanced state. The wind speed control mechanism and the wind separation simulation mechanism are fixedly installed on the balance chamber. One end of the wind speed control mechanism is connected to the balance chamber, and the other end is connected to the wind separation simulation mechanism.

[0009] Furthermore, the temperature and humidity control mechanism also includes a temperature and humidity sensor disposed in the balance chamber, which is used to detect the temperature and humidity of the balance chamber.

[0010] Furthermore, the wind speed control mechanism includes a speed-regulating fan fixedly installed on the temperature and humidity control mechanism, an air supply duct extending in the temperature and humidity control mechanism, and a wind speed adjustment component provided on the air supply duct. The air inlet of the speed-regulating fan is connected to the temperature and humidity control mechanism, and the air outlet is connected to the air supply duct. The air supply duct is connected to the wind selection simulation mechanism.

[0011] Furthermore, the wind speed regulating component includes an anemometer installed on the air supply duct and an electric air valve installed on the air supply duct. The anemometer is used to monitor the wind speed supplied by the air supply duct, and the electric air valve is used to regulate the wind speed supplied by the air supply duct.

[0012] Furthermore, the air separation simulation mechanism includes a feeding component connected to the wind speed control mechanism, an air outlet component connected to the temperature and humidity control mechanism, and a conical air duct connecting the feeding component and the air outlet component. The feeding component is used to feed tobacco shreds, the wind speed control mechanism drives the tobacco shreds loaded in the feeding component to spiral upward in the conical air duct, and the air outlet component is used to return the air delivered by the wind speed control mechanism to the temperature and humidity control mechanism.

[0013] Furthermore, the feeding assembly includes a sealed feeding chamber, a feeding drawer slidably connected to the sealed feeding chamber, an air inlet located on one side of the sealed feeding chamber, and a feeding box located in the feeding drawer. The feeding box is used to load tobacco shreds, and the feeding drawer is used to transport the loaded tobacco shreds to the sealed feeding chamber. The air inlet is connected to the wind speed control mechanism, and one end of the conical air duct is connected to the sealed feeding chamber.

[0014] Furthermore, the air outlet assembly includes a sealed air outlet chamber, an air outlet located on one side of the sealed air outlet chamber, and an air outlet filter located at the bottom of the sealed air outlet chamber. The other end of the conical air duct is connected to the bottom of the sealed air outlet chamber, and the air outlet is connected to the temperature and humidity control mechanism.

[0015] Furthermore, the wind speed control mechanism also includes a rotary reversing component disposed on the air supply duct, the rotary reversing component being used to change the wind direction of the air supplied by the air supply duct.

[0016] Furthermore, the air supply duct includes an air supply pipe connected to the speed-regulating fan, a return air pipe connected to the interior of the temperature and humidity control mechanism, an air inlet pipe connected to the feeding assembly, and an air outlet pipe connected to the air outlet assembly. The rotary reversing assembly is used to control the air supply pipe to connect with the air inlet pipe or the air outlet pipe, and to control the return air pipe to connect with the air inlet pipe or the air outlet pipe.

[0017] Furthermore, the rotary reversing assembly includes an upper fixed plate and a lower fixed plate arranged in parallel intervals, a connecting column that fixes the upper fixed plate and the lower fixed plate together, a reversing plate disposed between the upper fixed plate and the lower fixed plate, and a rotary cylinder fixed on the lower fixed plate. The air supply pipe and the air return pipe are connected to the upper fixed plate, and the air inlet pipe and the air outlet pipe are connected to the lower fixed plate. The rotary cylinder drives the reversing plate to rotate, thereby controlling the air supply pipe to communicate with the air inlet pipe or the air outlet pipe, and controlling the air return pipe to communicate with the air inlet pipe or the air outlet pipe.

[0018] The multi-environment tobacco air separation simulation device proposed in this invention has the following beneficial effects:

[0019] (1) This device regulates the temperature and humidity of its internal environment through a temperature and humidity regulating mechanism. The wind speed regulating mechanism delivers the air that has been regulated by the temperature and humidity regulating mechanism to the wind classifying simulation mechanism, driving the tobacco shreds to move in the wind classifying simulation mechanism, so that the wind classifying simulation mechanism performs wind classifying operation on the tobacco shreds. At the same time, the wind speed of the wind classifying simulation mechanism for wind classifying the tobacco shreds is adjusted, thereby simulating the wind classifying operation on the tobacco shreds under different environmental conditions such as temperature, humidity, and wind speed, so as to accurately evaluate the influence of different environmental factors on the wind classifying effect of tobacco shreds, thereby optimizing the wind classifying process of tobacco shreds and improving the quality and production efficiency of tobacco shreds products.

[0020] (2) The temperature and humidity control mechanism of this device includes a balance chamber and a constant temperature and humidity unit. The balance chamber and the constant temperature and humidity unit are fixedly installed on the frame. The constant temperature and humidity unit is located below the balance chamber and connected to the balance chamber. The temperature and humidity of the balance chamber are controlled by the constant temperature and humidity unit. The balance chamber adjusts and maintains the temperature and humidity of its internal environment in a balanced state, so that the temperature and humidity of the internal environment of the balance chamber reach and are maintained at the set value.

[0021] (3) The temperature and humidity control mechanism of this device also includes a temperature and humidity sensor. The temperature and humidity sensor is installed in the balance chamber. The temperature and humidity of the environment inside the balance chamber are detected by the temperature and humidity sensor, and the detected signal is transmitted to the control system. The control system controls the constant temperature and humidity unit to regulate the temperature and humidity of the environment inside the balance chamber, thereby achieving precise regulation of the temperature and humidity of the environment inside the balance chamber.

[0022] (4) The wind speed adjustment component of this device is installed on the air supply duct. When the air supply duct sends air to the air separation simulation mechanism and drives the tobacco to move in the air separation simulation mechanism, the wind speed adjustment component adjusts the wind speed of the air supply duct, thereby realizing the simulation of the tobacco air separation process under different wind speed environments.

[0023] (5) The wind speed adjustment component of this device includes an anemometer and an electric air valve. Both the anemometer and the electric air valve are installed on the air supply duct. When the air supply duct supplies air to the air selection simulation mechanism, the anemometer monitors the wind speed supplied by the air supply duct and transmits the monitored signal to the control system. The control system controls the electric air valve to adjust the wind speed supplied by the air supply duct, thereby achieving precise control of the wind speed supplied by the air supply duct.

[0024] (6) One end of the conical air duct of this device is connected to the feeding component. After the feeding component completes the feeding of tobacco, the feeding component is ventilated through the air supply pipe to drive the tobacco loaded in the feeding component to spirally rise in the conical air duct. During the spiraling rise of the tobacco in the conical air duct, the tobacco is separated from the impurities in the tobacco under the action of centrifugal force, thereby realizing the simulation of the tobacco air separation process.

[0025] (7) The other end of the conical air duct of this device is connected to the air outlet assembly. When the air outlet assembly is fixedly connected to the balance chamber, it is connected to the inside of the balance chamber. The air delivered to the feeding assembly by the air supply pipe flows through the conical air duct and is then returned to the balance chamber through the air outlet assembly, thereby realizing the recycling of air. This makes the structure of this device simple and convenient, easy to implement, and reduces the cost of using this device.

[0026] (8) The feeding assembly of this device includes a sealed feeding chamber and a feeding drawer. The feeding drawer is equipped with a feeding box for loading tobacco. The feeding drawer is slidably connected to the sealed feeding chamber. When the feeding drawer is pulled out from the sealed feeding chamber, the tobacco can be loaded into the feeding box. When it is inserted into the sealed feeding chamber, the tobacco loaded in the feeding box is transported to the sealed feeding chamber, thus making the feeding of tobacco simple, convenient and easy to implement.

[0027] (9) The air outlet filter of this device is set at the connection between the conical air duct and the sealed air outlet chamber, so that the air delivered by the air supply duct to the sealed feeding chamber flows through the conical air duct, then flows through the air outlet filter to the sealed air outlet chamber, and is returned to the balance chamber through the air outlet. During this process, the air outlet filter blocks the tobacco in the conical air duct, thereby realizing the recovery of air in the balance chamber, reducing the operating cost of this device, and preventing tobacco from entering the balance chamber and affecting the working performance of the balance chamber.

[0028] (10) The wind speed control mechanism of this device also includes a rotary reversing component. The rotary reversing component is installed on the air supply duct. After the simulation of the tobacco air supply process is completed, the air supply direction of the air duct is reversed by the rotary reversing component, driving the tobacco in the tobacco supply duct assembly to flow back to the feeding box, so that the tobacco in the tobacco supply duct assembly can be cleaned and recycled after the experiment.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1-9An embodiment of the present invention provides a multi-environment tobacco air separation simulation device, including a temperature and humidity control mechanism, a wind speed control mechanism 3 fixedly installed on the temperature and humidity control mechanism, and an air separation simulation mechanism 4 fixedly installed on the temperature and humidity control mechanism. One end of the wind speed control mechanism 3 is connected to the temperature and humidity control mechanism, and the other end is connected to the air separation simulation mechanism 4.

[0042] The temperature and humidity control mechanism is used to adjust the temperature and humidity of its internal environment to the set value. The air separation simulation mechanism 4 is loaded with tobacco. The wind speed control mechanism 3 delivers the air inside the temperature and humidity control mechanism to the air separation simulation mechanism 4 and controls the wind speed of the air supply to drive the tobacco to move in the air separation simulation mechanism 4. During the movement of the tobacco in the air separation simulation mechanism 4, the air separation simulation mechanism 4 performs air separation on the tobacco.

[0043] In this application, the multi-environment tobacco air separation simulation device includes a temperature and humidity control mechanism, a wind speed control mechanism 3, and an air separation simulation mechanism 4. The wind speed control mechanism 3 and the air separation simulation mechanism 4 are both fixedly installed on the temperature and humidity control mechanism, which is used to adjust the temperature and humidity of its internal environment to the set value.

[0044] One end of the wind speed control mechanism 3 is connected to the temperature and humidity control mechanism, and the other end is connected to the air separation simulation mechanism 4. Thus, the air whose temperature and humidity inside the temperature and humidity control mechanism are adjusted to the set value is delivered to the air separation simulation mechanism 4 through the wind speed control mechanism 3.

[0045] Tobacco shreds are loaded into the air separation simulation mechanism 4. Air is supplied through the wind speed control mechanism 3, driving the tobacco shreds to move within the air separation simulation mechanism 4. During the movement of the tobacco shreds in the air separation simulation mechanism 4, the air separation simulation mechanism 4 performs air separation on the tobacco shreds, thereby simulating the tobacco air separation process in an environment with set temperature and humidity values. Furthermore, by adjusting the set values ​​during multiple simulations, the simulation of the tobacco air separation process in different temperature and humidity environments can be achieved.

[0046] In this application, when the air whose temperature and humidity inside the temperature and humidity regulating mechanism is adjusted to a set value is delivered to the air separation simulation mechanism 4 by the wind speed regulating mechanism 3, the wind speed regulating mechanism 3 can also control the wind speed of the air supply, thereby controlling the wind speed of the air separation simulation mechanism 4 to perform air separation on the tobacco, thereby realizing the simulation of the tobacco air separation process under different wind speed environments.

[0047] Therefore, in this application, the temperature and humidity of the internal environment are regulated by a temperature and humidity regulating mechanism, and the wind speed regulating mechanism 3 delivers the temperature and humidity regulated air inside the temperature and humidity regulating mechanism to the wind separation simulation mechanism 4, driving the tobacco shreds to move in the wind separation simulation mechanism 4, so that the wind separation simulation mechanism 4 performs wind separation operation on the tobacco shreds. At the same time, the wind speed of the wind separation simulation mechanism 4 for wind separation of tobacco shreds is adjusted, thereby simulating wind separation operation on tobacco shreds under different environmental conditions such as temperature, humidity, and wind speed, so as to accurately evaluate the impact of different environmental factors on the wind separation effect of tobacco shreds, thereby optimizing the tobacco shreds wind separation process and improving the quality and production efficiency of tobacco products.

[0048] Specifically, in this embodiment, the temperature and humidity control mechanism includes a balance chamber 1 and a constant temperature and humidity unit 2. Specifically, the balance chamber 1 and the constant temperature and humidity unit 2 are fixedly installed on the frame. The constant temperature and humidity unit 2 is located below the balance chamber 1 and connected to the balance chamber 1, so that the temperature and humidity of the balance chamber 1 are controlled by the constant temperature and humidity unit 2. The balance chamber 1 adjusts and maintains the temperature and humidity of its internal environment in a balanced state, so that the temperature and humidity of the internal environment of the balance chamber 1 reach and are maintained at the set value.

[0049] The wind speed control mechanism 3 and the wind separation simulation mechanism 4 are fixedly installed on the balance chamber 1. One end of the wind speed control mechanism 3 is connected to the balance chamber 1 and the other end is connected to the wind separation simulation mechanism 4. Thus, when the wind speed control mechanism 3 is activated, the air in the balance chamber 1 with the set temperature and humidity is transported to the wind separation simulation mechanism 4.

[0050] The air separation simulation mechanism 4 is loaded with tobacco shreds. Air is supplied through the wind speed control mechanism 3, and the wind speed is adjusted to drive the tobacco shreds to move in the air separation simulation mechanism 4. The air separation simulation mechanism 4 performs air separation operation on the tobacco shreds, thereby simulating the air separation operation on the tobacco shreds under different environmental conditions such as temperature, humidity, and wind speed. This allows for accurate evaluation of the impact of different environmental factors on the air separation effect of tobacco shreds, thereby optimizing the tobacco shred air separation process and improving the quality and production efficiency of tobacco products.

[0051] In this application, the specific structure and working principle of the balance chamber 1 and the constant temperature and humidity unit 2 are common knowledge that should be known to those skilled in the art, and therefore will not be described in detail here.

[0052] Furthermore, in this embodiment, the temperature and humidity control mechanism also includes a temperature and humidity sensor 11, which is installed in the balance chamber 1. The temperature and humidity sensor 11 detects the temperature and humidity of the internal environment of the balance chamber 1 and transmits the detected signal to the control system. The control system controls the constant temperature and humidity unit 2 to regulate the temperature and humidity of the internal environment of the balance chamber 1, thereby achieving precise regulation of the temperature and humidity of the internal environment of the balance chamber 1.

[0053] After being regulated by the constant temperature and humidity unit 2 and adjusted by the balance chamber 1 itself, the temperature and humidity of the internal environment of the balance chamber 1 reach and are maintained at the set value. Then, the air in the balance chamber 1 with the set temperature and humidity is delivered to the air separation simulation mechanism 4 through the wind speed control mechanism 3, driving the tobacco to move in the air separation simulation mechanism 4, so that the air separation simulation mechanism 4 performs air separation operation on the tobacco, thereby simulating the air separation process of tobacco under different temperature, humidity and wind speed environments.

[0054] In this embodiment, the wind speed control mechanism 3 includes a speed-regulating fan 31, an air supply duct 32, and a wind speed adjustment component. The speed-regulating fan 31 is fixedly installed on the temperature and humidity control mechanism. The air supply duct 32 extends in the temperature and humidity control mechanism. The air inlet of the speed-regulating fan 31 is connected to the temperature and humidity control mechanism, and the air outlet is connected to the air supply duct 32. The air supply duct 32 is connected to the air separation simulation mechanism 4. The wind speed adjustment component is installed on the air supply duct 32.

[0055] Specifically, in this application, the variable speed fan 31 is fixedly installed on the balance chamber 1, thereby achieving the fixed installation of the wind speed control mechanism 3 on the balance chamber 1. The air supply duct 32 extends in the balance chamber 1, and the air inlet of the variable speed fan 31 is connected to the balance chamber 1, and the air outlet is connected to the air supply duct 32. Thus, when the variable speed fan 31 is started, the air in the balance chamber 1 with the set temperature and humidity is transported to the air separation simulation mechanism 4 through the air supply duct 32, driving the tobacco to move in the air separation simulation mechanism 4, so that the air separation simulation mechanism 4 performs air separation operation on the tobacco, thereby simulating the tobacco air separation process in different temperature and humidity environments.

[0056] The wind speed adjustment component is installed on the air supply duct 32. When the air supply duct 32 supplies air to the air separation simulation mechanism 4 and drives the tobacco to move in the air separation simulation mechanism 4, the wind speed adjustment component adjusts the wind speed supplied by the air supply duct 32, thereby simulating the tobacco air separation process under different wind speed environments.

[0057] Specifically, in this embodiment, the wind speed regulation component includes an anemometer 33 and an electric air valve 34, both of which are mounted on the air supply duct 32. When the air supply duct 32 supplies air to the air separation simulation mechanism 4, the anemometer 33 monitors the wind speed supplied by the air supply duct 32 and transmits the monitored signal to the control system. The control system then controls the electric air valve 34 to regulate the wind speed supplied by the air supply duct 32, thereby achieving precise regulation of the wind speed supplied by the air supply duct 32.

[0058] By regulating the wind speed of the wind speed adjustment component, the wind speed of the air supplied by the air supply duct 32 is maintained at the set value. Thus, the air supply duct 32 supplies air to the air separation simulation mechanism 4 at the set wind speed, driving the tobacco shreds to move in the air separation simulation mechanism 4. The air separation simulation mechanism 4 performs air separation of the tobacco shreds under the set wind speed, thereby simulating the tobacco shred air separation process under different wind speed environments.

[0059] It is foreseeable that, in actual implementation, the wind speed regulating component in this embodiment is not limited to the electric air valve 34, but may also be other devices or equipment that can regulate the wind speed of the air supply duct 32.

[0060] In this embodiment, the air separation simulation mechanism 4 includes a feeding component 41, an air outlet component 42, and a conical air duct 43. The feeding component 41 is connected to the wind speed control mechanism 3, the air outlet component 42 is connected to the temperature and humidity control mechanism, and the conical air duct 43 is disposed between the feeding component 41 and the air outlet component 42, and connects the feeding component 41 and the air outlet component 42.

[0061] Specifically, in this application, both the feeding assembly 41 and the air outlet assembly 42 are fixedly connected to the balance chamber 1, thereby achieving the fixed installation of the air separation simulation mechanism 4 on the balance chamber 1. When the feeding assembly 41 is fixedly connected to the balance chamber 1, it is connected to the air supply duct 32 extending inside the balance chamber 1, so that when the speed-regulating fan 31 is started, the air in the balance chamber 1 with the set temperature and humidity is transported to the feeding assembly 41 through the air supply duct 32.

[0062] The feeding assembly 41 is used to feed tobacco shreds, and one end of the conical air duct 43 is connected to the feeding assembly 41. After the feeding assembly 41 completes the feeding of tobacco shreds, air is supplied to the feeding assembly 41 through the air supply duct 32, driving the tobacco shreds loaded in the feeding assembly 41 to spiral upward in the conical air duct 43. During the spiral ascent of the tobacco shreds in the conical air duct 43, under the action of centrifugal force, the tobacco shreds are separated from the impurities in the tobacco shreds, thereby simulating the tobacco shred air separation process.

[0063] The other end of the conical air duct 43 is connected to the air outlet assembly 42. When the air outlet assembly 42 is fixedly connected to the balance chamber 1, it is connected to the inside of the balance chamber 1. The air delivered by the air supply duct 32 to the feeding assembly 41 flows through the conical air duct 43 and is then returned to the balance chamber 1 through the air outlet assembly 42, thereby realizing the recycling of air. This makes the structure of the device simple, convenient, and easy to implement, and reduces the cost of using the device.

[0064] In this embodiment, the feeding assembly 41 includes a sealed feeding chamber 411 and a feeding drawer 412. An air inlet 4111 is provided on one side of the sealed feeding chamber 411, and the air inlet 4111 is connected to the wind speed control mechanism 3. One end of the conical air duct 43 is connected to the sealed feeding chamber 411. A feeding box 4121 is provided in the feeding drawer 412, and the feeding box 4121 is used to load tobacco.

[0065] The feeding drawer 412 is slidably connected to the sealed feeding chamber 411. Specifically, a slide rail is provided at the bottom of the feeding drawer 412, and the slide rail is slidably connected to the sealed feeding chamber 411, thereby realizing the slidable connection between the feeding drawer 412 and the sealed feeding chamber 411.

[0066] When the feeding drawer 412 is pulled out of the sealed feeding chamber 411 through the sliding engagement of the slide rail with the sealed feeding chamber 411, the tobacco can be loaded into the feeding box 4121; when the feeding drawer 412 is inserted into the sealed feeding chamber 411 through the sliding engagement of the slide rail with the sealed feeding chamber 411, the tobacco loaded in the feeding box 4121 is transported to the sealed feeding chamber 411, thus making the feeding of tobacco simple, convenient and easy to implement.

[0067] Specifically, in this application, the air inlet 4111 extends horizontally on one side of the sealed feeding chamber 411, and when the sealed feeding chamber 411 is fixedly connected to the balance chamber 1, it is connected to the air supply duct 32 extending inside the balance chamber 1, so that when the speed-regulating fan 31 is started, the air in the balance chamber 1 with the temperature and humidity reaching the set value is transported horizontally to the sealed feeding chamber 411 through the air supply duct 32 and the air inlet 4111.

[0068] When one end of the conical air duct 43 is connected to the sealed feeding chamber 411, it extends vertically at the top of the sealed feeding chamber 411 and communicates with the interior of the sealed feeding chamber 411. When the air supply duct 32 horizontally supplies air to the sealed feeding chamber 411 through the air inlet 4111, it spirals upward along the cylindrical inner wall of the sealed feeding chamber 411, thereby driving the tobacco loaded in the feeding box 4121 to spiral upward in the conical air duct 43. Then, under the action of centrifugal force, the impurities in the tobacco are removed, realizing the simulation of the tobacco air separation process.

[0069] In this embodiment, the air outlet assembly 42 includes a sealed air outlet chamber 421, an air outlet 4211, and an air outlet filter 422. The sealed air outlet chamber 421 is fixedly connected to the temperature and humidity control mechanism. The air outlet 4211 is located on one side of the sealed air outlet chamber 421 and is connected to the temperature and humidity control mechanism when the sealed air outlet chamber 421 is fixedly connected to the temperature and humidity control mechanism.

[0070] Specifically, when the sealed air outlet chamber 421 is fixedly connected to the balance chamber 1, the air outlet 4211 is connected to the balance chamber 1, so that the air delivered by the air supply duct 32 to the sealed feeding chamber 411 flows through the conical air supply duct 43 and then flows to the sealed air outlet chamber 421, and is returned to the balance chamber 1 through the air outlet 4211 on one side of the sealed air outlet chamber 421, thereby realizing the recycling of air, making the structure of the device simple and convenient, easy to implement, and reducing the operating cost of the device.

[0071] The other end of the conical air duct 43 is connected to the bottom of the sealed air outlet chamber 421. The air outlet filter 422 is fixedly installed at the bottom of the sealed air outlet chamber 421. That is, the air outlet filter 422 is installed at the connection between the conical air duct 43 and the sealed air outlet chamber 421, so that the air delivered by the air supply duct 32 to the sealed feeding chamber 411 flows through the conical air duct 43, passes through the air outlet filter 422 and flows to the sealed air outlet chamber 421, and is returned to the balance chamber 1 through the air outlet 4211.

[0072] During this process, the air outlet filter 422 blocks the tobacco in the conical air duct 43, thereby realizing the recovery of air in the balance chamber 1, reducing the operating cost of the device, and preventing tobacco from entering the balance chamber 1 and affecting its working performance.

[0073] Furthermore, in this embodiment, the wind speed control mechanism 3 also includes a rotary reversing component 35, which is disposed on the air supply duct 32. When the speed-regulating fan 31 is started, it delivers air from the balance chamber 1 to the air supply duct 32 at the set temperature and humidity. When air is supplied to the sealed feeding chamber 411 through the air supply duct 32, the rotary reversing component 35 can change the airflow direction of the air supply duct 32. Thus, after simulating the tobacco air separation process, the rotary reversing component 35 reverses the airflow direction of the air duct, driving the tobacco in the conical air duct 43 to flow back to the feeding box 4121.

[0074] On the one hand, it facilitates the cleaning of tobacco in the conical duct 43 after the experiment, preventing residual tobacco in the conical duct 43 from affecting the accuracy of subsequent experimental data; on the other hand, after the tobacco in the conical duct 43 flows back to the feeding box 4121, the tobacco in the feeding box 4121 can be taken out for recycling, thereby further reducing tobacco waste and lowering production costs.

[0075] Specifically, in this embodiment, the air supply duct 32 includes an air supply duct 321, a return air duct 322, an inlet air duct 323, and an outlet air duct 324. The air supply duct 321 located in the balance chamber 1 is connected to the speed-regulating fan 31, and the return air duct 322 located in the balance chamber 1 is connected to the internal environment of the balance chamber 1.

[0076] When the sealed feeding chamber 411 and the sealed air outlet chamber 421 are fixedly connected to the balance chamber 1, the air inlet pipe 323 located in the balance chamber 1 is connected to the air inlet 4111 on one side of the sealed feeding chamber 411, and the air outlet pipe 324 located in the balance chamber 1 is connected to the air outlet 4211 on one side of the sealed air outlet chamber 421. The rotary reversing assembly 35 is used to control the connection between the air supply pipe 321 and the air inlet pipe 323 or the air outlet pipe 324, and to control the connection between the return air pipe 322 and the air inlet pipe 323 or the air outlet pipe 324.

[0077] Specifically, during the simulation of tobacco air separation, the rotary reversing component 35 controls the air supply pipe 321 to connect with the air inlet pipe 323 and the return air pipe 322 to connect with the air outlet pipe 324. The speed regulating fan 31 is started, and the air in the balance chamber 1 is sequentially delivered to the air supply pipe 321 and the air inlet pipe 323. The air inlet pipe 323 delivers air to the sealed feeding chamber 4111 through the air inlet 4111, driving the tobacco loaded in the feeding box 4121 to spiral upward in the conical air duct 43.

[0078] The air supplied by the air supply duct 32 to the sealed feeding chamber 411 flows through the conical air supply duct 43 and then to the sealed air outlet chamber 421. It is then sent out through the air outlet 4211 on one side of the sealed air outlet chamber 421, and then flows back to the balance chamber 1 after passing through the air outlet 324 and the return air duct 322 in sequence, thus completing the air circulation of the tobacco air separation simulation process.

[0079] After the tobacco air separation simulation is completed, the rotary reversing component 35 controls the connection between the air supply pipe 321 and the air outlet pipe 324, and the connection between the return air pipe 322 and the air inlet pipe 323. The speed-regulating fan 31 starts, and the air in the balance chamber 1 is sequentially delivered to the air supply pipe 321 and the air outlet pipe 324. The air outlet pipe 324 delivers air to the sealed air outlet chamber 421 through the air outlet 4211, driving the tobacco in the conical air duct 43 to flow back to the feeding box 4121. The air flowing through the feeding box 4121 and the sealed feeding chamber 411 is sent out through the air inlet 4111 of the sealed feeding chamber 411, and then flows back to the balance chamber 1 after sequentially flowing through the air inlet pipe 323 and the return air pipe 322, thus completing the air circulation of the tobacco recycling process.

[0080] As mentioned in the previous embodiments, an air outlet filter 422 is provided at the connection between the conical air duct 43 and the sealed air outlet chamber 421 to block the tobacco in the conical air duct 43 during the tobacco air separation simulation, preventing the tobacco from entering the balance chamber 1 through the sealed air outlet chamber 421. Therefore, in this application, the side wall and bottom wall of the feeding box 4121 can be set as a filter structure to block the tobacco in the feeding box 4121 during the tobacco recycling process, preventing the tobacco from entering the balance chamber 1 through the sealed feeding chamber 411, so as to ensure the working performance of the balance chamber 1.

[0081] Specifically, in this embodiment, the rotary reversing assembly 35 includes an upper fixed plate 351, a lower fixed plate 352, a connecting column 353, a reversing plate 354, and a rotary cylinder 355. The upper fixed plate 351 and the lower fixed plate 352 are arranged parallel to each other in the vertical direction. The connecting column 353 fixes the upper fixed plate 351 and the lower fixed plate 352 together. The reversing plate 354 is disposed between the upper fixed plate 351 and the lower fixed plate 352. The rotary cylinder 355 is fixedly disposed on the side of the lower fixed plate 352 facing the upper fixed plate 351.

[0082] Both the supply air duct 321 and the return air duct 322 are connected to the upper fixed plate 351, and both the inlet air duct 323 and the outlet air duct 324 are connected to the lower fixed plate 352. The rotary cylinder 355 is connected to the reversing plate 354. The rotary cylinder 355 drives the reversing plate 354 to rotate, thereby controlling the supply air duct 321 to connect with the inlet air duct 323 or the outlet air duct 324, and controlling the return air duct 322 to connect with the inlet air duct 323 or the outlet air duct 324, thus realizing the reversal of the air supply from the supply air duct 32.

[0083] Specifically, in this embodiment, the upper fixed plate 351 is provided with an air supply connector 3511 and a return air connector 3512. The air supply pipe 321 is connected to the upper fixed plate 351 through the air supply connector 3511 and is connected to the air supply connector 3511. The return air pipe 322 is connected to the upper fixed plate 351 through the return air connector 3512 and is connected to the return air connector 3512.

[0084] The lower fixed plate 352 is provided with an air inlet connector 3521 and an air outlet connector 3522. The air inlet pipe 323 is connected to the lower fixed plate 352 through the air inlet connector 3521 and is connected to the air inlet connector 3521. The air outlet pipe 324 is connected to the lower fixed plate 352 through the air outlet connector 3522 and is connected to the air outlet connector 3522.

[0085] The reversing disc 354 is provided with a first channel 3541, a second channel 3542, a third channel 3543, and a fourth channel 3544. The first channel 3541 and the second channel 3542 are interconnected, and the third channel 3543 is interconnected with the fourth channel 3544. During the forward and reverse rotation of the reversing disc 354 driven by the rotary cylinder 355, the first channel 3541 switches between connecting to the air supply connector 3511 or the air outlet connector 3522; the second channel 3542 switches between connecting to the air inlet connector 3521 or the air supply connector 3511; the third channel 3543 switches between connecting to the return air connector 3512 or the air inlet connector 3521; and the fourth channel 3544 switches between connecting to the air outlet connector 3522 or the return air connector 3512.

[0086] Specifically, during the simulation of tobacco air separation, the rotary cylinder 355 drives the reversing disk 354 to rotate in the forward direction, so that the first channel 3541 is switched to connect with the air supply connector 3511, the second channel 3542 is switched to connect with the air inlet connector 3521, the third channel 3543 is switched to connect with the return air connector 3512, and the fourth channel 3544 is switched to connect with the air outlet connector 3522.

[0087] Since the air supply pipe 321 is connected to the air supply connector 3511, the air inlet pipe 323 is connected to the air inlet connector 3521, and the first channel 3541 is connected to the second channel 3542, when the first channel 3541 is connected to the air supply connector 3511 and the second channel 3542 is connected to the air inlet connector 3521, the air supply pipe 321 is connected to the air inlet pipe 323, so that the air supply pipe 321 supplies air to the sealed feeding chamber 411 through the air inlet pipe 323 and the air inlet 4111, driving the tobacco loaded in the feeding box 4121 to spiral upward in the conical air pipe 43.

[0088] Since the return air duct 322 is connected to the return air connector 3512, the outlet air duct 324 is connected to the outlet air connector 3522, and the third channel 3543 is connected to the fourth channel 3544, when the third channel 3543 is connected to the return air connector 3512 and the fourth channel 3544 is connected to the outlet air connector 3522, the outlet air duct 324 is connected to the return air duct 322. This allows the air delivered from the outlet 4211 on one side of the sealed outlet air chamber 421 to flow through the outlet air duct 324 and the return air duct 322 in sequence before returning to the balance chamber 1, thus completing the air circulation of the tobacco air separation simulation process.

[0089] After the tobacco air separation simulation is completed, the rotary cylinder 355 drives the reversing disk 354 to rotate in the opposite direction, so that the first channel 3541 is switched to connect with the air outlet connector 3522, the second channel 3542 is switched to connect with the air supply connector 3511, the third channel 3543 is switched to connect with the air inlet connector 3521, and the fourth channel 3544 is switched to connect with the return air connector 3512.

[0090] Similarly, when the first channel 3541 is connected to the air outlet connector 3522 and the second channel 3542 is connected to the air supply connector 3511, the air supply pipe 321 is connected to the air outlet pipe 324, so that the air supply pipe 321 supplies air to the sealed air outlet chamber 421 through the air outlet pipe 324 and the air outlet 4211, driving the tobacco in the conical air pipe 43 to flow back to the feeding box 4121.

[0091] When the third channel 3543 is connected to the air inlet connector 3521 and the fourth channel 3544 is connected to the return air connector 3512, the air inlet pipe 323 and the return air pipe 322 are connected, so that the air sent out from the air inlet 4111 on the side of the sealed feeding chamber 411 flows through the air inlet pipe 323 and the return air pipe 322 in sequence and then flows back into the balance chamber 1, thereby completing the air circulation of the tobacco recycling process.
