Description

Technical Field

[0001] This invention relates to intelligent control technology for re-moistening, specifically an intelligent control system for the re-moistening of tobacco after curing. Background Technology

[0002] In existing technologies, tobacco leaves are often directly baked during the curing process. This can cause dirt or water droplets remaining on the outer surface of the leaves to affect the normal heating effect, resulting in poor processing. If the moisture content of the tobacco leaves obtained from the rehumidification process is insufficient, the humidity data inside the rehumidification machine needs to be reset, and the humidity needs to be gradually adjusted based on the output. This adjustment process leads to a certain amount of poor-quality tobacco leaves, causing economic losses to users. Broken tobacco leaves are not removed during the rehumidification process and are conveyed to subsequent steps. Broken leaves are small and lightweight, and they can easily cause blockages in the equipment gaps during transport, affecting the normal operation of the rehumidification equipment. Tobacco leaves are often bundled together during both curing and rehumidification, causing them to overlap and negatively impacting the curing and rehumidification effects. Furthermore, different tobacco leaves vary in size, and even when using the same hanging curing and rehumidification method, some contact surfaces may not achieve adequate curing and rehumidification.

[0003] To address the aforementioned technical problems, this application proposes a solution. Summary of the Invention

[0004] The purpose of this invention is to compare the humidity data of tobacco leaves before rehumidification and adjust the wetting time according to the humidity of the tobacco leaves. This prevents the tobacco leaves from failing to meet the standard humidity after rehumidification, which would require further wetting or drying and delay the progress and speed of the tobacco rehumidification process. By arranging multiple adjusting rods in a spiral shape, the space occupied is reduced while preventing the tobacco leaves from stacking. The sliding baffle opens and closes repeatedly under the traction of the second traction rope on the rotating disk, allowing the size of the atomizing nozzle area to be adjusted with the rotation of the tobacco leaves, thus saving water resources. This solves the problems of needing to conduct multiple tests to determine the optimal humidity when the rehumidification is not good, resulting in the waste of experimental tobacco leaves, and the stacking of tobacco leaves affecting the rehumidification effect and easily causing water waste. Therefore, this invention proposes an intelligent control system for the rehumidification of cured tobacco.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A smart control system for the re-moistening of flue-cured tobacco includes:

[0007] The tobacco leaf detection module is used to collect color data, humidity data, breakage data and size data of tobacco leaves before and after the re-moistening operation, and obtain color data of tobacco before curing, humidity data of tobacco before re-moistening, humidity data of tobacco after re-moistening, breakage data of tobacco before re-moistening and breakage data of tobacco after re-moistening. The obtained data is then passed to the data comparison module for processing.

[0008] The data comparison module is used to compare the color data of tobacco leaves before curing, compare the color changes on the surface of the tobacco leaves before curing, and determine whether the curing of the tobacco leaves is uniform; it is used to compare the humidity data of tobacco leaves before and after re-moistening, compare the humidity changes before and after the re-moistening operation, and determine whether the re-moistening operation of the tobacco leaves is uniform; it is used to compare the breakage data of tobacco leaves before and after re-moistening, compare the change in the integrity of the tobacco leaves before and after the re-moistening operation, and determine whether the re-moistening operation has caused damage to the tobacco leaves.

[0009] The operation execution module is used to receive the execution signals transmitted from the data comparison module and execute the corresponding execution operations through various structures inside the rehumidifier.

[0010] In a preferred embodiment of the present invention, the data comparison module receives the pre-curing tobacco color data transmitted from the tobacco leaf detection module and compares the pre-curing tobacco color data. The data comparison process is as follows:

[0011] Step 1: Perform grayscale processing on the image representing the pre-curing tobacco color data of each tobacco leaf transmitted from the tobacco leaf detection module. Then, divide the grayscale processed image into equal-sized blocks and calculate the grayscale value of each block to obtain the block grayscale value hd. Calculate the average of the grayscale values ​​of multiple blocks corresponding to each tobacco leaf to obtain the average grayscale value HD of the block represented by each tobacco leaf.

[0012] Step 2: Retrieve the grayscale value hd corresponding to each tobacco leaf block, and then compare each block's grayscale value hd with the average grayscale value HD of the pre-curing block represented by that tobacco leaf. If one or more blocks in the tobacco leaf segmentation have a grayscale value that differs from the average grayscale value of the pre-curing block by a set grayscale difference value, then the tobacco leaf is marked as a differential tobacco leaf, a cleaning signal is generated, and the cleaning signal is transmitted to the operation execution module. After the operation execution module completes the cleaning operation of the tobacco leaf, it performs the grayscale comparison operation on the tobacco leaf again; otherwise, the tobacco leaf curing operation is performed.

[0013] Step 3: Record the average gray value of the pre-curing block represented by each tobacco leaf, and obtain the range of average gray values ​​{HD} for this batch of tobacco leaves representing the pre-curing block. max HD min, the gray - scale mean range before baking is divided into several small gray - scale mean ranges HDx of equal size. According to the size of the gray - scale mean range HDx of the pre - baking block, the tobacco leaves are baked in sequence. During the baking process, according to different gray - scale mean ranges of the pre - baking block, the tobacco leaves are baked at corresponding temperatures. After baking, the tobacco leaves are classified according to the corresponding gray - scale mean range HDx of the pre - baking block.

[0014] As a preferred embodiment of the present invention, the data comparison module receives the humidity data of the tobacco leaves before and after re - humidification transmitted from the tobacco leaf detection module, and compares the humidity data of the tobacco leaves before and after re - humidification. The data comparison process is as follows:

[0015] Step 1: Compare the received humidity data HCq of the tobacco leaves before re - humidification with the set humidity data HCqs before re - humidification. If HCq < HCqs, it is determined that the tobacco leaves are too dry and prone to breakage, and the tobacco leaves are marked as long - time wetted tobacco leaves; if HCq > HCqs, it is determined that the tobacco leaves are not completely dried, and the tobacco leaves are marked as short - time wetted tobacco leaves; if HCq = HCqs, then retrieve the humidity data of the tobacco leaves after re - humidification for comparison, and retrieve the temperature data T and humidity data RH in the re - humidification box during the re - humidification operation when the humidity data HCh after re - humidification is equal to the set humidity data HChs. According to the ratio of HCqs and HChs, calculate the required temperature data t and humidity data rh in the re - humidification box at other pre - re - humidification humidities, t = [T×(HCqs - HCq)×HCqs] / HChs, rh = [RH×(HCqs - HCq)×HCqs] / HChs;

[0016] Step 2: If HCh ≠ HChs, it is determined that the re - humidification operation is abnormal. For the tobacco leaves with HCh > HChs, a drying execution signal is generated, and the drying operation is performed through the execution module; for the tobacco leaves with HCh < HChs, a humidification execution signal is generated, and the humidification operation is performed through the execution module.

[0017] As a preferred embodiment of the present invention, the data comparison module receives the breakage data of the tobacco leaves before and after re - humidification transmitted from the tobacco leaf detection module, and compares the breakage data of the tobacco leaves before and after re - humidification. The data comparison process is as follows:

[0018] By comparing the grayscale image data obtained through grayscale processing with the color data before curing, and by using the segmentation mesh of the grayscale image processing, the area size of the tobacco leaf in the grayscale image can be calculated, thus obtaining the area data Sk of the tobacco leaf before curing. Through grayscale processing, the area data Sq and Sh of the tobacco leaf before and after re-moistening can be obtained. If Sk = Sq and Sq > Sh, it is determined that the tobacco leaf was broken during the re-moistening operation, and the breakage data Ss = 100% × (1 - Sh / Sq). If Ss > 20%, it is determined that the degree of damage to the tobacco leaf affects subsequent processing operations.

[0019] In a preferred embodiment of the present invention, a rehumidification machine is provided with a rehumidification clamp plate, which includes an adjusting linkage. Two gripping plates are integrally formed on one side of the outer wall of the adjusting linkage. A gripping hole is provided at the middle position of the upper surface of the gripping plate. A tobacco leaf body is provided on the inner side of the gripping plate corresponding to the position of the gripping hole. A driver is installed at the middle position of the upper surface of the adjusting linkage. A linkage groove is provided inside the adjusting linkage corresponding to the position of the driver. A rotating shaft is rotatably connected at the middle position of the lower surface of the linkage groove. A rotating groove is provided at the middle position of the inner side of the gripping hole. A rotating ring is rotatably connected inside the rotating groove. A telescopic groove is provided in each of the four directions on the inner side of the rotating ring. A clamping block is slidably connected inside the telescopic groove via an energized spring. A transmission groove is provided at the middle position of the outer wall of the rotating ring. A transmission wheel is rotatably connected to the outer wall of the rotating shaft corresponding to the position of the rotating ring. The transmission wheel is connected to the rotating ring via a transmission belt.

[0020] In a preferred embodiment of the present invention, both ends of the adjusting linkage are provided with sliding grooves, and telescopic rods are slidably connected inside the sliding grooves. A connecting rotating head is integrally formed at the end of each of the two telescopic rods away from the adjusting linkage. A traction rope is connected to each of the two connecting rotating heads inside the linkage groove. A rotating ring is rotatably connected to the outer wall of the rotating shaft at the position corresponding to the traction rope. Several evenly distributed slots are provided on the outer wall of the rotating shaft. A telescopic groove is provided inside the rotating ring. A limiting rod is slidably connected inside the telescopic groove via an energized spring. A rotating gear is installed at the middle position of the outer wall of the rotating shaft. Telescopic grooves are provided on both sides of the linkage groove corresponding to the rotating gear. A rotation limiting head is slidably connected inside the telescopic groove via an energized spring.

[0021] In a preferred embodiment of the present invention, a transmission box is installed on the upper surface of the adjusting linkage corresponding to the position of the driver. Rotary disks are rotatably connected to both sides of the upper surface of the transmission box. A damping plate is installed on the outer wall of the transmission box corresponding to the position of the gripping plate. Several evenly distributed atomizing nozzles are installed on the outer wall of the damping plate near the gripping plate. A rotating connector is rotatably connected to the outer surface of the rotating disk. A second traction rope is connected to one side of the outer wall of the rotating connector.

A slider is installed on the outer wall of the sliding baffle corresponding to the position of the limiting groove.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. By comparing and treating the ash content of tobacco leaves before curing, cleaning is performed on tobacco leaves with significant differences in ash content to remove dirt and impurities that could affect the curing effect. The curing process involves applying appropriate temperatures to tobacco leaves with different ash content ranges to prevent over- or under-curing of leaves due to using the same temperature for leaves of varying maturity. Humidity data of the tobacco leaves before re-moistening is compared, and the wetting time is adjusted accordingly to prevent the leaves from failing to meet humidity standards after re-moistening, which would necessitate further wetting or drying and delay the re-moistening process. Furthermore, the degree of leaf breakage is assessed to prevent severely damaged leaves from flowing to the next process and to prevent equipment blockage caused by broken leaves during subsequent processing.

[0024] 2. The exposed length of the telescopic rod inside the adjusting linkage is adjusted under the action of the first traction rope, so that the length of the adjusting linkage and the telescopic rod is equal to the width of the tobacco leaf being clamped, preventing the tobacco leaves from contacting each other. The angle of adjacent telescopic rods can be adjusted by rotating the connecting head, allowing multiple adjusting linkages to be arranged in a spiral shape, reducing the space occupied and preventing the tobacco leaves from stacking. During the rotation of the rotating shaft, the rotating disks on both sides and the rotating ring one that clamps the tobacco leaves also rotate, causing the sliding baffle to open and close repeatedly under the traction of the second traction rope on the rotating disk. This allows the size of the atomizing nozzle area to be adjusted with the rotation of the tobacco leaves, further saving water resources. Attached Figure Description

[0031] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0032] Example 1:

[0033] Please see Figure 1-4 As shown, an intelligent control system for the re-moistening of flue-cured tobacco includes a tobacco leaf detection module, a data comparison module, and a wiping execution module.

[0034] Comparison of color data of tobacco before roasting:

[0035] The image representing the color data of each tobacco leaf before curing, transmitted from the tobacco leaf detection module, is processed in grayscale. Then, the image representing the color data of the tobacco leaf before curing is divided into blocks of equal size, and the grayscale value of each block is calculated to obtain the block grayscale value hd. The average grayscale value of the block corresponding to each tobacco leaf is calculated by summing the grayscale values ​​of multiple blocks and taking the average value to obtain the average grayscale value HD of the block represented by each tobacco leaf.

[0036] Retrieve the block gray value hd corresponding to each tobacco leaf, and then compare each block gray value hd with the average gray value HD of the pre-baked block represented by the tobacco leaf. If there is one or more block gray values in the tobacco leaf segmentation blocks that differ from the average gray value of the pre-baked block by more than the set gray difference value, mark the tobacco leaf as a different tobacco leaf, generate a cleaning signal, and transmit the cleaning signal to the operation execution module. After the operation execution module completes the cleaning operation on the tobacco leaf, perform the gray comparison operation on the tobacco leaf again; otherwise, perform the baking operation on the tobacco leaf;

[0037] Record the average gray value of the pre-baked block represented by each tobacco leaf to obtain the range of the average gray value of the pre-baked block represented by this batch of tobacco leaves {HD max , HD min}, divide the range of the average gray value of the pre-baked block into several small ranges of the average gray value of the pre-baked block HDx according to equal-sized ranges of the average gray value, and perform the baking treatment on the tobacco leaves in sequence according to the size of the range of the average gray value of the pre-baked block HDx. When performing the baking treatment, bake the tobacco leaves at the corresponding temperature according to different ranges of the average gray value of the pre-baked block, and classify the baked tobacco leaves according to the corresponding range of the average gray value of the pre-baked block HDx;

[0038] In the prior art, when baking tobacco leaves, the tobacco leaves are often directly baked, so that the dirt attached to the outside of the tobacco leaves or the water droplets that are not cleaned after cleaning affect the normal heat absorption effect on the surface of the tobacco leaves during the baking operation, resulting in poor treatment effect of the baking on the tobacco leaves;

[0039] Data comparison of the humidity data of tobacco before and after conditioning:

[0040] Compare the received humidity data HCq of tobacco before conditioning with the set humidity data HCqs before conditioning. If HCq < HCqs, it is determined that the tobacco leaf is too dry and prone to breakage, and mark the tobacco leaf as a long-time moistened tobacco leaf; if HCq > HCqs, it is determined that the tobacco leaf is not completely dried, and mark the tobacco leaf as a short-time moistened tobacco leaf; if HCq = HCqs, retrieve the humidity data of the tobacco leaf after conditioning for comparison, and retrieve the temperature data T and humidity data RH in the conditioning box when the humidity data HCh of the tobacco leaf after conditioning is equal to the set humidity data HChs after conditioning; calculate the required temperature data t and humidity data rh in the conditioning box at other humidity levels before conditioning according to the ratio of HCqs and HChs, t = [T×(HCqs - HCq)×HCqs] / HChs, rh = [RH×(HCqs - HCq)×HCqs] / HChs;

[0041] If HCh ≠ HChs, it is determined that the conditioning operation is abnormal. For the tobacco leaves with HCh > HChs, a drying execution signal is generated, and the drying operation is carried out through the execution module; for the tobacco leaves with HCh < HChs, a humidifying execution signal is generated, and the humidifying operation is carried out through the execution module;

[0042] In the prior art, during the conditioning operation of tobacco leaves, if the humidity of the tobacco leaves obtained from the conditioning operation is not good, the humidity data inside the conditioner needs to be reset, and then the humidity is gradually adjusted according to the produced tobacco leaves. During the adjustment process, the quality of a certain amount of produced tobacco leaves is not good, causing economic losses to users;

[0043] Data comparison of the tobacco leaf breakage degree data before and after conditioning:

[0044] Through the grayscale image data obtained by grayscale processing when comparing the color data before baking, and the divided wire meshes of the grayscale image processing, the area size of the tobacco leaves in the grayscale processed image can be calculated to obtain the area data Sk of the tobacco leaves before baking. Through the grayscale processing method, the area data Sq and Sh of the tobacco leaves before and after conditioning can be obtained. If Sk = Sq and Sq > Sh, it is determined that the tobacco leaves are broken during the conditioning operation, and the breakage degree data Ss = 100% × (1 - Sh / Sq). If Ss > 20%, it is determined that the breakage degree of the tobacco leaves affects the subsequent processing operation;

[0045] In the prior art, the broken tobacco leaves are not removed during the conditioning operation. The broken tobacco leaves are transmitted to the subsequent steps along with the processing procedures. The broken tobacco leaves are small in volume and light in weight, and are likely to cause blockage of the equipment gaps during the transmission process, affecting the normal operation of the conditioning operation equipment.

[0046] Embodiment 2:

[0047] Please refer to Figure 1-4As shown, the rehumidifier is equipped with a rehumidification clamp, which includes an adjusting rod 2. Two gripping plates 3 are integrally formed on one side of the outer wall of the adjusting rod 2. The two gripping plates 3 are distributed vertically, making the tobacco leaf body 1 gripped by the gripping plates 3 more stable. A gripping hole 16 is opened in the middle of the upper surface of the gripping plate 3. The tobacco leaf body 1 is placed in the gripping hole 16 position on the inner side of the gripping plate 3. The root part of the tobacco leaf body 1 is placed in the gripping hole 16 position, making the root part harder and less prone to breakage. A driver 7 is installed in the middle of the upper surface of the adjusting rod 2. The output end of the driver 7 is connected to the rotating shaft 20. A linkage groove 6 is opened inside the adjusting rod 2 in the position corresponding to the driver 7. The rotating shaft 20 is rotatably connected in the middle of the lower surface of the linkage groove 6. A rotating groove is provided in the middle position, and a rotating ring 14 is rotatably connected inside the rotating groove. A telescopic groove is provided in each of the four directions on the inner side of the rotating ring 14. A clamping block 15 is slidably connected inside the telescopic groove through an energized spring 2. The extension and retraction of the energized spring 2 are controlled by the on and off of the energized spring 2, which pushes the clamping block 15 to extend and retract. A transmission groove is provided in the middle position of the outer wall of the rotating ring 14. A transmission wheel is rotatably connected to the outer wall of the rotating shaft 20 at the position corresponding to the rotating ring 14. The transmission wheel is connected to the rotating ring 14 through a transmission belt. The rotation of the output end of the driver 7 drives the rotation of the rotating shaft 20. The transmission wheel connected to the rotating shaft 20 drives the rotating ring 14 to rotate through the transmission belt, so that the tobacco body 1 clamped inside the rotating ring 14 rotates.

[0048] Both ends of the adjusting linkage 2 are provided with sliding grooves, and telescopic rods 5 are slidably connected inside the sliding grooves. A connecting head 4 is integrally formed at the end of each telescopic rod 5 away from the adjusting linkage 2. The telescopic rods 5 at both ends can be docked and rotated through the connecting head 4. Traction ropes 13 are connected inside the linkage groove 6 at positions corresponding to the two connecting heads 4. One end of the traction rope 13 is connected to one side of the telescopic rod 5, and the other end is connected to a rotating ring 2 on the outer side of the rotating shaft 20. A rotating ring 2 is rotatably connected to the outer wall of the rotating shaft 20 at the position corresponding to the traction rope 13. The outer wall of the rotating shaft 20 has several evenly distributed slots. The inner side of the rotating ring 2 has a telescopic groove 3. The telescopic groove 3 is slidably connected to a limit rod through an energized spring 3. A rotating gear 21 is installed at the middle position of the outer wall of the rotating shaft 20. The two sides of the linkage groove 6 are provided with telescopic grooves 2 18 corresponding to the position of the rotating gear 21. The telescopic groove 2 18 is slidably connected to a rotation limiting head 17 through an energized spring 19. The position of the rotation limiting head 17 is controlled by the extension and retraction of the energized spring 19, thereby limiting the rotation of the rotating gear 21.

[0049] A transmission box 9 is installed on the upper surface of the adjusting linkage 2 at the position corresponding to the driver 7. Inside the transmission box 9, a double rotating wheel is installed on the outer side of the rotating shaft 20. A rotating wheel is also installed on the outer side of the rotating shaft connected to the rotating disk 8. The rotating wheels and the double rotating wheels are connected by a transmission belt, allowing the driver 7 to drive the two rotating disks 8 to rotate. Rotating disks 8 are rotatably connected to both sides of the upper surface of the transmission box 9. A damping plate 12 is installed on the outer wall of the transmission box 9 at the position corresponding to the gripping plate 3. Several evenly distributed atomizing nozzles are installed on the outer wall of the damping plate 12 near the gripping plate 3. Atomizing nozzles are connected to the damping plate 12 via pipes, and a switch valve is installed on the pipes. A rotating connector 10 is rotatably connected to the outer side of the upper surface of the rotating disk 8. The rotating connector 10 prevents the traction rope from getting tangled during the rotation of the rotating disk 8. A second traction rope is connected to one side of the outer wall of the wet plate 10. Multiple limit rings are installed on the outer wall of the wet plate 12 at the position corresponding to the second traction rope. Sliding baffles 11 are slidably connected to both sides of the outer wall of the wet plate 12 near the gripping plate 3. A push plate is installed at the position of the pipe connected to the atomizing nozzle of the sliding baffle 11. When the push plate slides to one side, the switch valves on the pipes along the sliding path can be opened in sequence. When sliding in the opposite direction, the switch valves on the pipes along the sliding path can be closed in sequence. A limit groove is opened on the outer wall of the wet plate 12 at the position corresponding to the sliding baffle 11. A telescopic spring is installed inside the limit groove. When the sliding baffle 11 moves to one side, the telescopic spring deforms and stretches. When the sliding baffle 11 is not subjected to external force, it can drive the sliding baffle 11 to reset its position. A slider is installed on the outer wall of the sliding baffle 11 at the position corresponding to the limit groove.

[0050] In the existing technology, when tobacco leaves are baked and rehydrated, they are often directly bundled together, causing them to overlap and cover each other. This results in a negative impact on the baking and rehydration effects. Furthermore, since different tobacco leaves vary in size, even when the same method is used for hanging baking and rehydration, the contact surfaces may not achieve good baking and rehydration results.

[0051] After the worker places the tobacco leaf body 1 inside the gripping plate 3 outside the adjusting linkage 2, the tobacco leaf detection module detects the presence of the tobacco leaf body 1 inside the gripping hole 16 on the inner side of the gripping plate 3. This de-energizes the second energized spring of the clamping block 15, causing the clamping block 15 to clamp the tobacco leaf body 1 under the action of the second energized spring. Then, based on the detected size data of the tobacco leaf body 1, the tobacco leaf detection module drives the output end of the driver 7 to rotate. The output end of the driver 7 is connected to the rotating shaft 20. When the rotating shaft 20 rotates, the rotating ring... The de-energization of the inner spring three causes the limiting rod to insert into the slot on the rotating shaft 20. This rotation of the rotating shaft 20 drives the rotating ring two, causing the traction rope 13 to wind up. The telescopic rod 5, extending to the outside, moves inward under the traction of the traction rope 13. When the distance measured by the rangefinder inside the linkage slot 6 is sufficient to make the extension length of the telescopic rods 5 and the length of the adjusting linkage 2 equal to the width of the tobacco body 1, the energized spring three contracts, causing the limiting rod to... The rod is pulled out from the slot on the rotating shaft 20, and the second rotating ring no longer rotates with the rotation of the rotating shaft 20. The limiting structure inside the linkage groove 6 limits the second rotating ring. During the rotation of the rotating shaft 20, the transmission wheel on the rotating shaft 20 drives the first rotating ring 14 to rotate, so that the tobacco body 1 held inside the first rotating ring 14 rotates with the rotation of the first rotating ring 14. When the rotating shaft 20 rotates, it also drives the two rotating disks 8 to rotate through the internal structure of the transmission box 9. When the rotating disks 8 rotate, they slide through the second traction rope. When the movable baffle 11 is pulled and moved, and the rotating shaft 20 drives the rotating ring 14 to rotate a quarter turn, the rotating shaft 20 drives the rotating disk 8 to rotate half a turn. That is, when the tobacco body 1 rotates from being horizontal with the damping plate 12 to being perpendicular to the damping plate 12, the sliding baffle 11 slides from the outermost side to the innermost side, so that only the atomizing nozzle in the middle position on the damping plate 12 is working. The size of the working atomizing nozzle changes with the rotation of the tobacco body 1, preventing the waste of water resources caused by the operation of unnecessary atomizing nozzles.
