Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tobacco industry equipment, in particular to a high-precision joint control system for the curing environment of a multi-bin tobacco curing test box. BACKGROUND

[0002] The tobacco industry plays an important role in the national economy.

[0003] Tobacco leaves are of various types, and even the same type of tobacco leaves grown in different regions and in different years have different qualities. Therefore, in the modern tobacco industry, in order to obtain the best quality products, a small amount of tobacco leaves are sent into a tobacco curing test box for trial production before large-scale curing (including baking or airing) of the tobacco leaves, so as to obtain the key production parameters (such as the control curve of temperature and humidity) for obtaining the best quality products through the trial, and then produce on a large scale according to the key production parameters.

[0004] For the existing tobacco curing test box, only one tobacco curing bin is provided, and the test usually needs to simulate different environmental parameters multiple times, and then compare the qualities of the products produced under different environmental parameters, and finally select the best environmental parameters. However, if only one existing tobacco curing test box is used, the test period will be extremely long, and the delay in production may affect the quality of a large amount of tobacco to be processed. If multiple tobacco curing test boxes are used, although the above problem can be effectively solved, the equipment procurement cost is high, a large amount of space is required for placing the equipment, and more manpower is required for operating the equipment.

[0005] In addition, the hot air circulation structure of the existing tobacco curing test box is also very simple, and the heating device is usually arranged at the bottom or top of the tobacco curing bin, and the hot air circulation mode from bottom to top or from top to bottom is used to heat the tobacco curing bin. However, the existing hot air circulation structure inevitably leads to poor temperature uniformity at different positions in the tobacco curing bin (usually the closer to the heating device, the higher the temperature), and uneven temperature of the tobacco curing bin may not only lead to unsatisfactory quality of the cured products obtained through the test, but also more likely to lead to inaccurate temperature control curve in the best environmental parameters obtained, thereby affecting the quality of the products obtained through subsequent large-scale production.

[0006] In addition, the existing tobacco curing test box usually uses multiple fixedly installed humidity sensors arranged in the tobacco curing bin for humidity monitoring, which not only has high cost, but also due to the large difference in humidity uniformity at different positions in the tobacco curing bin, even if multiple fixedly installed humidity sensors are used, it is difficult to accurately reflect the humidity at different positions in the tobacco curing bin, and the deviation is usually very large, thereby leading to inaccurate humidity control curve in the best environmental parameters obtained, and affecting the quality of the products obtained through subsequent large-scale production.

[0007] Solving the above problems has become a top priority. SUMMARY

[0008] Therefore, the present application provides a multi-bin tobacco conditioning test box conditioning environment high-precision joint control system.

[0009] The technical scheme is as follows:

[0010] The first aspect of the present application relates to a multi-bin tobacco conditioning test box conditioning environment high-precision joint control system, comprising a test box body, the inside of the test box body is separated to form a heating air duct, a dehumidification channel and a plurality of tobacco conditioning bins which are independent of each other, the dehumidification channel is arranged at the bottom of the heating air duct, each tobacco conditioning bin is arranged around the heating air duct, and at least one return air port communicating with the air inlet end of the heating air duct, at least one dehumidification port communicating with the air inlet end of the dehumidification channel and at least one air inlet port communicating with the outside are formed in each tobacco conditioning bin.

[0011] The adjustable balanced air supply module communicating with the air outlet of the heating air duct is installed in each tobacco conditioning bin, the adjustable balanced air supply module has a plurality of hot air outlets arranged in an array on one side wall of the corresponding tobacco conditioning bin, and the air volume of each hot air outlet can be adjusted, the heating device for heating air and the circulating power device for conveying the air entering the return air port to the adjustable balanced air supply module are arranged in the heating air duct, the dehumidification power device for conveying the air entering the dehumidification port to the outside is arranged in the dehumidification channel, and the air inlet opening and closing control mechanism for controlling the opening size of the air inlet port is installed at the air inlet port.

[0012] A three-dimensional full-coverage temperature and humidity acquisition mechanism is installed in each tobacco conditioning bin, and the three-dimensional full-coverage temperature and humidity acquisition mechanism comprises a temperature and humidity sensor and a sensor position control mechanism for adjusting the spatial position of the temperature and humidity sensor in the corresponding tobacco conditioning bin.

[0013] The above multi-bin tobacco conditioning test box conditioning environment high-precision joint control system has the following technical effects:

[0014] 1. Since a plurality of tobacco conditioning bins can be arranged in one tobacco conditioning test box, different environmental parameters can be simulated in each tobacco conditioning bin, and the test can be carried out synchronously, which not only greatly shortens the test period, ensures the quality of the subsequent product, and also greatly reduces the equipment investment cost, has a high structural integration, saves equipment placement space, and reduces the number of operators.

[0015] 2. Since each tobacco curing chamber is equipped with multiple hot air outlets arrayed on one side wall, and the temperature and humidity sensors can move freely within the three-dimensional space of the tobacco curing chamber, full-coverage temperature collection of the internal space of the tobacco curing chamber can be achieved. The collected temperature data is used as a reference for adjusting the air volume of each hot air outlet, which not only realizes intelligent control, but also ensures that the temperature in various locations in the tobacco curing chamber remains relatively uniform at a very high level.

[0016] 3. Since the temperature and humidity sensor can move freely in the three-dimensional space of the tobacco curing chamber, it can also achieve full coverage of humidity collection in the internal space of the tobacco curing chamber. The collected humidity data is used as a reference for the air inlet opening and closing control mechanism to adjust the size of the air inlet opening and the start and stop of the dehumidification power device. This not only realizes intelligent control, but also enables the humidity in various locations in the tobacco curing chamber to be kept relatively uniform to a certain extent.

[0017] 4. The above-mentioned methods ensure that the optimal environmental parameters obtained in the final screening are highly accurate under the premise of efficient testing, thereby guiding subsequent large-scale production to obtain high-quality products and ultimately ensuring the ideal profit. Furthermore, the tobacco curing test chamber of the present invention not only has a large internal space but also has multiple tobacco curing chambers, so it can also be used for small-batch production of tobacco products (including baking and drying), and is especially suitable for the production of high-end, high-quality, small-batch tobacco products.

[0040] The present application is further described below in conjunction with embodiments and drawings.

[0041] As Figures 1-12 shown, a multi-bin type tobacco leaf conditioning test box conditioning environment high-precision joint control system mainly comprises a test box body 1, the test box body 1 is internally partitioned to form a heating air duct 11, a dehumidification passage 16 and a plurality of tobacco leaf conditioning bins 12 which are independent of each other.

[0042] Each tobacco leaf conditioning bin 12 surrounds the heating air duct 11, and at least one air return port 13 which communicates with the air inlet end of the heating air duct 11, at least one dehumidification port 17 which communicates with the air inlet end of the dehumidification passage 16 and at least one air inlet port 18 which communicates with the outside are formed in the tobacco leaf conditioning bin 12. Meanwhile, the air outlet end of the heating air duct 11 is provided with an air outlet port 15 for supplying air to each tobacco leaf conditioning bin 12. At the same time, since moisture moves upward in space and hot air moves downward in space, the air return port 13 is formed at the lower end of the heating air duct 11, and the air outlet port 15 is formed at the upper end of the heating air duct 11. Correspondingly, the dehumidification passage 16 is arranged at the bottom of the heating air duct 11 in the present embodiment. In the present embodiment, the heating air duct 11 and the dehumidification passage 16 are composed of one large pipe, and the lower part of the large pipe is partitioned by a partition plate 111 to form the heating air duct 11 and the dehumidification passage 16 which are distributed above and below, which is simple, reliable and easy to manufacture.

[0043] The heating device 5 for heating air and the circulating power device 6 for conveying the air entering the air return port 13 to the adjustable balanced air supply module 2 are arranged in the heating air duct 11. Therefore, under the action of the circulating power device 6, the air in the tobacco leaf conditioning bin 12 enters the heating air duct 11 through the air return port 13, is heated by the heating device 5, and then circulates back to the tobacco leaf conditioning bin 12 through the air outlet port 15. At the same time, the dehumidification passage 16 is provided with a dehumidification power device 9 for conveying the air entering the dehumidification port 17 to the outside, and the air inlet opening and closing control mechanism 8 for controlling the opening size of the air inlet port 18 is arranged at the air inlet port 18. Therefore, under the action of the dehumidification power device 9, the moisture in the tobacco leaf conditioning bin 12 can be sucked into the dehumidification passage 16 through the dehumidification port 17 and then discharged to the outside, and at the same time, fresh air from the outside can be supplemented to the tobacco leaf conditioning bin 12 through the air inlet port 18.

[0044] In the embodiment, the inside of the test box body 1 is divided to form a heating air duct 11 and a plurality of tobacco conditioning warehouses 12, and each tobacco conditioning warehouse 12 is annularly arranged around the heating air duct 11. Since a plurality of tobacco conditioning warehouses 12 can be arranged in one tobacco conditioning test box, different environmental parameters can be simulated in each tobacco conditioning warehouse 12, and tests can be simultaneously performed. This not only greatly shortens the test period, but also ensures the quality of subsequent products, and the large amount of fresh tobacco to be processed does not need to be subjected to long waiting. In addition, compared with the traditional method of using a plurality of tobacco conditioning test boxes, the method of using one set of heating device 5 and circulating power device 6 and one set of dehumidifying power device 9 in cooperation with a plurality of tobacco conditioning warehouses 12 greatly reduces the equipment investment cost and has high structural integration, saves equipment placement space, and can also reduce the number of operating personnel.

[0045] Please refer to Figure 2 and Figure 3 In the embodiment, the heating device 5 is preferably arranged at a position close to the return air outlet 13 of the heating air duct 11, and the circulating power device 6 is preferably arranged at a position close to the air outlet 15 of the heating air duct 11. Such design not only ensures the heating capacity of the heating device 5 for air, but also enables the circulating power device 6 to have greater performance and improve the flow rate of air.

[0046] The heating device 5 preferably adopts finned heating pipes, which have large heat exchange area and improve the heat exchange performance for air. The circulating power device 6 preferably adopts a multi-fan combination installation method, which can control the air volume of a single fan and adjust the number of on-off fans, thereby having a large air volume adjustment range and high flexibility.

[0047] Please refer to Figure 3 and Figure 4 The dehumidifying power device 9 preferably adopts an air volume adjustable exhaust fan, which can flexibly adjust the dehumidification speed.

[0048] Please refer to Figure 2 and Figure 6, the tobacco conditioning bin 12 is divided into two parts by the orifice plate 19, the orifice plate 19 is provided with an array of air holes 191, the exhaust port 17, the air inlet 18 and the air inlet opening and closing control mechanism 8 are located below the corresponding orifice plate 19, the air return port 13, the adjustable balanced air supply module 2 and the three-dimensional full-coverage temperature and humidity collection mechanism 4 are located above the corresponding orifice plate 19. Through such design, it can not only prevent the residues generated by tobacco conditioning from falling to the bottom of the test box 1, but also facilitate cleaning, and can also take into account the smoothness of the exhaust and the smoothness of the hot air circulation. Specifically, due to the blocking effect of the orifice plate 19, the air in the tobacco conditioning bin 12 can be efficiently circulated into the air return port 13, and most of the moisture in the tobacco conditioning bin 12 will also be settled into the space below the orifice plate 19. Once the exhaust power device 9 is started and the air inlet 18 is opened, the moisture in the tobacco conditioning bin 12 can be efficiently and quickly exhausted, and the hot air can also be retained in the tobacco conditioning bin 12 as much as possible, improving the efficiency, control accuracy and energy saving of tobacco conditioning.

[0049] Please refer to Figure 4 and Figure 6 , the adjustable balanced air supply module 2 is installed in the tobacco conditioning bin 12 and communicates with the air outlet 15 of the heating air duct 11, the adjustable balanced air supply module 2 has a plurality of hot air outlets 212 arranged in an array on one side wall of the corresponding tobacco conditioning bin 12, and the air volume of each hot air outlet 212 can be adjusted. Therefore, since each tobacco conditioning bin 12 is provided with a plurality of hot air outlets 212 arranged in an array on one side wall thereof, and the air volume of each hot air outlet 212 can be adjusted, the temperature at each position in the tobacco conditioning bin 12 can be kept relatively uniform at a very high level, so that not only can the conditioning product with very ideal quality be obtained from the test, but also the best environmental parameters obtained through final screening can have excellent accuracy, thereby guiding subsequent large-scale production to obtain high-quality products, and further ensuring that ideal benefits are finally obtained.

[0050] Specifically, the adjustable balanced air supply module 2 includes a plurality of air supply assemblies 21 arranged side by side from top to bottom, and a main air supply pipeline 22 for simultaneously supplying air to each air supply assembly 21, the air inlet end of the main air supply pipeline 22 communicates with the air outlet 15 of the heating air duct 11, that is, the main air supply pipeline 22 simultaneously supplies air to all air supply assemblies 21.

[0051] The air supply assembly 21 comprises an end air supply pipeline 211 installed on one side wall of the tobacco conditioning warehouse 12 in a horizontal direction. For the same tobacco conditioning warehouse 12, the end air supply pipelines 211 are arranged side by side from top to bottom, and each has a plurality of hot air outlets 212 distributed in a horizontal direction. The end air supply pipeline 211 is communicated with the corresponding main air supply pipeline 22 through the intermediate air supply pipeline 23, and the intermediate air supply pipeline 23 is provided with the air volume adjusting assembly 24 for adjusting the hot air flux. Therefore, a large number of hot air outlets 212 form a dot matrix on a plane, so as to form a three-dimensional air supply in the tobacco conditioning warehouse 12. Since the air volume of each hot air outlet 212 can be adjusted, the temperature at each position in the tobacco conditioning warehouse 12 can be kept relatively uniform at a very high level. In addition, the air volume of each hot air outlet 212 on each end air supply pipeline 211 is synchronously adjusted by the air volume adjusting assembly 24 installed on the intermediate air supply pipeline 23. This can keep the temperature at each position in the tobacco conditioning warehouse 12 relatively uniform at a very high level, and the number of air volume adjusting assemblies 24 is small, which reduces the equipment cost and the difficulty of control, and is convenient for maintenance.

[0052] Further, in the same tobacco conditioning warehouse 12, the end air supply pipelines 211 are uniformly distributed from top to bottom. On the same end air supply pipeline 211, the hot air outlets 212 are uniformly distributed in a horizontal direction. Therefore, the hot air outlets 212 are arranged in an array, which can simplify the control method and make it easier to keep the temperature at each position in the tobacco conditioning warehouse 12 uniform.

[0053] Please refer to Figure 6 The hot air outlet 212 has a horn structure gradually increasing away from the corresponding end air supply pipeline 211, so as to guide the air to uniformly expand in the outlet direction, thereby increasing the coverage area of the air outlet. Meanwhile, the outer end surface of the hot air outlet 212 is covered with an air uniformizing plate 213, which is provided with an array of air outlet holes 213a. The array of small holes can make the air outlet more uniform, thereby making the heating of the tobacco at each position more uniform and greatly improving the quality of the final product obtained by tobacco conditioning.

[0054] Please refer to Figure 6 and Figure 7The air volume adjusting assembly 24 comprises a valve plate 241 rotatably installed in the intermediate air supply pipeline 23 and a valve plate driving steering engine 242 for controlling the rotation of the valve plate 241. The size and shape of the valve plate 241 are adapted to the size and shape of the cross section of the intermediate air supply pipeline 23. The rotation of the valve plate 241 is driven by the valve plate driving steering engine 242 to adjust the opening of the valve plate 241, so as to accurately adjust the flux of the intermediate air supply pipeline 23 and accurately control the air volume.

[0055] Please refer to Figure 4 and Figure 6 In each tobacco conditioning warehouse 12, the side wall provided with the air supply assembly 21 is installed with an air supply assembly cover plate 25 covering the main air supply pipeline 22, the intermediate air supply pipelines 23 and the air volume adjusting assemblies 24. Only the terminal air supply pipelines 211 are exposed outside the air supply assembly cover plate 25. Through such design, the protection function of the internal components is realized, the visual angle is avoided from being cluttered, and the internal space of the tobacco conditioning warehouse 12 is easy to clean.

[0056] Meanwhile, the air supply assembly cover plate 25 is also convenient for installing the tobacco hanging assembly 3. Specifically, please refer to Figure 4 , Figure 5 , Figure 10 and Figure 11 In the same tobacco conditioning warehouse 12, the air supply assembly cover plate 25 and the opposite side wall of the tobacco conditioning warehouse 12 are provided with at least one set of tobacco hanging assemblies 3 from top to bottom in parallel. The tobacco hanging assemblies 3 on the two side walls of the tobacco conditioning warehouse 12 correspond to each other, so as to facilitate the hanging of tobacco.

[0057] The tobacco hanging assembly 3 comprises a tobacco hanging lower plate 31 extending in the horizontal direction and a tobacco hanging upper plate 33 installed above the tobacco hanging lower plate 31 through at least one weight sensor 32. The tobacco is hung on the tobacco hanging upper plate 33 through the tobacco rod, and the weight sensor 32 can monitor the weight change of the tobacco in real time to calculate the water loss rate, so as to determine the stage of the tobacco conditioning.

[0058] Meanwhile, please refer to Figure 4 and Figure 5 The bottom and top of the tobacco conditioning warehouse 12 are installed with visual cameras 7. The visual cameras 7 can not only monitor the color change of the tobacco in real time, so as to determine the accurate stage of the tobacco conditioning (roasting or airing) in the conditioning period, especially in combination with the water loss rate information collected by the weight sensor 32, to ensure the accuracy of the stage determination; but also can provide the basis for obstacle avoidance for the operation of the three-dimensional full-coverage temperature and humidity collecting mechanism 4, to avoid the risk of collision or entanglement of the temperature and humidity sensor 41 (see the following description in detail).

[0059] Further, the test box body 1 is provided with cabinet doors 14 corresponding to each tobacco leaf conditioning bin 12, and each cabinet door 14 is provided with a large-size observation window 141 for close observation of the color change and conditioning of the tobacco leaves.

[0060] Please refer to Figure 4 , Figure 10 and Figure 11 , the hanging tobacco lower plate 31 is preferably fixedly installed on the air supply assembly cover plate 25 or the side wall opposite to the air supply assembly cover plate 25 of the tobacco leaf conditioning bin 12, and the hanging tobacco assembly 3 on the air supply assembly cover plate 25 corresponds to the hanging tobacco assembly 3 on the side wall opposite to the air supply assembly cover plate 25, so that the air outlet direction of each hot air outlet 212 is consistent (parallel) with the extension direction of the tobacco rod on which the tobacco leaves are hung, which can not only ensure the efficiency of baking or simulating the drying of tobacco leaves, but also improve the quality of tobacco conditioning. Meanwhile, the upper surface of the hanging tobacco upper plate 33 is recessed to form a support sliding groove 331 extending along the length direction thereof, at least one tobacco rod support 34 is installed in the support sliding groove 331 in sliding fit, and at least two support pulleys 341 are installed on the bottom of the tobacco rod support 34 and are uniformly distributed along the length direction of the support sliding groove 331. The groove bottom of the support sliding groove 331 is recessed to form pulley positioning grooves 331a uniformly distributed along the length direction thereof, the distance between the adjacent support pulleys 341 of the tobacco rod support 34 is equal to the distance between the adjacent pulley positioning grooves 331a of the support sliding groove 331, and each support pulley 341 of the tobacco rod support 34 is supported in the corresponding pulley positioning groove 331a. Through such design, the installation position of the tobacco rod support 34 can be adjusted very conveniently, and self-positioning and constraint based on gravity are easy to realize, and since the adjustment step is consistent, the two ends of the tobacco rod can be kept in synchronization on the two hanging tobacco upper plates 33 very conveniently and efficiently, and the tobacco rod is easy to keep perpendicular to the hanging tobacco upper plate 33, so that a row of tobacco leaves on the tobacco rod can reduce the blocking of hot air in space, and the internal temperature is easy to keep uniform, thereby improving the conditioning quality.

[0061] Further, the two ends of the tobacco rod support 34 in the length direction are provided with positioning bosses 343, which can avoid accidental falling of the tobacco rod. Meanwhile, the upper surface of the tobacco rod support 34 has a positioning groove 342 penetrating along the length direction thereof, so that the tobacco rod support 34 is suitable for different types of tobacco rods and has good universality.

[0062] Please refer to Figure 1 , the test box body 1 is further provided with a plurality of pulleys 10, so that the tobacco leaf conditioning test box is easy to be transferred as a whole, and each pulley 10 can be locked to ensure the stability and reliability of the installation of the tobacco leaf conditioning test box.

[0063] Please refer to Figure 5 and Figure 12The air inlet opening and closing control mechanism 8 includes an air inlet baffle 81 matched with the air inlet 18 and a third electric linear module 82 installed on the test box body 1. The air inlet baffle 81 is installed on the slider of the third electric linear module 82, and the third electric linear module 82 can drive the corresponding air inlet baffle 81 to slide along the inner wall of the corresponding tobacco processing bin 12 within the range of completely shielding the air inlet 18 and completely exposing the air inlet 18. The way of adjusting the opening size of the air inlet 18 by sliding the air inlet baffle 81 not only has high adjustment accuracy, but also has little effect on the air inlet compared with the rotating baffle, so as to ensure the accuracy of the air inlet control.

[0064] Please refer to Figures 4-6 and Figure 8 and Figure 9 The three-dimensional full-coverage temperature and humidity acquisition mechanism 4 is installed in each tobacco processing bin 12, and the three-dimensional full-coverage temperature and humidity acquisition mechanism 4 includes a temperature and humidity sensor 41 and a sensor position control mechanism 42 for adjusting the spatial position of the temperature and humidity sensor 41 in the corresponding tobacco processing bin 12. Therefore, the temperature and humidity sensor 41 can move to any position in the corresponding tobacco processing bin 12 under the control of the sensor position control mechanism 42.

[0065] Therefore, since each tobacco processing bin 12 is provided with a plurality of hot air outlets 212 arranged in an array on one side wall thereof, and the temperature and humidity sensor 41 can move arbitrarily in the three-dimensional space of the tobacco processing bin 12, full-coverage temperature acquisition of the internal space of the tobacco processing bin 12 is realized, and the acquired temperature data is used as a reference basis for adjusting the air outlet size of each hot air outlet 212, which not only realizes intelligent control, but also enables the temperature at each position in the tobacco processing bin 12 to be relatively uniform at a very high level. Similarly, since the temperature and humidity sensor 41 can move arbitrarily in the three-dimensional space of the tobacco processing bin 12, full-coverage humidity acquisition of the internal space of the tobacco processing bin 12 is also realized, and the acquired humidity data is used as a reference basis for adjusting the opening size of the air inlet 18 by the air inlet opening and closing control mechanism and starting and stopping the exhaust power device 9, which not only realizes intelligent control, but also enables the humidity at each position in the tobacco processing bin 12 to be relatively uniform at a certain level.

[0066] As can be seen from the above, the present embodiment can efficiently perform tests while ensuring that the best environmental parameters obtained through final screening have excellent accuracy, thereby guiding subsequent large-scale production to obtain high-quality products, and further ensuring that ideal benefits are ultimately obtained.

[0067] The sensor position control mechanism 42 each comprises a lifting control assembly and a two-dimensional translation assembly for adjusting the position of the lifting control assembly in the horizontal direction, the two-dimensional translation assembly is respectively installed at the top of the corresponding tobacco processing bin 12, the lifting control assembly each comprises a lifting assembly shell 421 installed on the corresponding two-dimensional translation assembly, a winch drive motor 423 installed on the lifting assembly shell 421, a winch 422 rotatably installed in the lifting assembly shell 421, and a cable 424 wound on the winch 422, a driving gear 425 is synchronously rotatable on the motor shaft of the winch drive motor 423, a driven gear 426 is synchronously rotatable on the winch 422 and meshes with the driving gear 425, and the outer end of the cable 424 is hung with a temperature and humidity sensor 41 after passing out of the lifting assembly shell 421, that is, the winch drive motor 423 drives the driving gear 425 to synchronously rotate, the driving gear 425 drives the driven gear 426 to rotate, and the driven gear 426 drives the winch 422 to synchronously rotate, and the control of the cable 424 can be realized by the back and forth rotation of the winch 422.

[0068] The above structure not only has high control precision, but also can reduce the risk of entanglement with the tobacco by the lifting type temperature and humidity sensor 41 control mode, and when the temperature and humidity sensor 41 collides during the lowering process, the winch drive motor 423 can quickly sense the reduction of torque, so as to recover the cable 424 and make the temperature and humidity sensor 41 quickly escape, thereby simplifying the control program. At the same time, combined with the internal image collected by the visual camera 7, the risk of collision and entanglement of the temperature and humidity sensor 41 can be greatly avoided.

[0069] The two-dimensional translation assembly each comprises a first electric linear module 427 and a sliding frame 428 installed in parallel on the top of the corresponding tobacco processing bin 12, and a second electric linear module 429 perpendicular to the first electric linear module 427 and the sliding frame 428, the slide rail of the second electric linear module 429 is installed on the sliding block of the first electric linear module 427 and the sliding block of the sliding frame 428, and the lifting assembly shell 421 is installed on the sliding block of the second electric linear module 429, so as to realize the translation control in the horizontal direction, the installation structure is simple and reliable, the operation is stable, and the control precision is high.

[0070] Finally, it should be noted that the above description is only for the preferred embodiments of the present application, and those skilled in the art can make various similar modifications under the inspiration of the present application without departing from the purpose and claims of the present application, and such modifications fall within the protection scope of the present application.
