Description

Technical Field

[0001] This utility model relates to the field of tobacco production technology, and in particular to a packaging and sampling mechanism. Background Technology

[0002] In the tobacco processing industry, threshing and re-drying is a crucial initial step. The main process includes rehydration, moistening, threshing and destemming, secondary drying, pre-packaging and boxing, re-packing and bundling, and finally, transporting the finished tobacco leaves to the warehouse. After threshing and re-drying, the raw tobacco leaves need to undergo aging in a aging warehouse, typically taking 2 to 5 years. During aging, to prevent mold and spoilage, the moisture content of the tobacco leaves must be strictly controlled. Therefore, before the tobacco leaves are stored, a quality inspection, especially moisture testing, is required.

[0003] In existing technologies, the tobacco leaves after packaging and repackaging are already compacted. Traditional manual sampling methods require tools to pry open the surface tobacco leaves to extract the internal samples. This not only disrupts the compacted state of the tobacco leaves but also lacks subsequent repair processes, resulting in loose tobacco leaves inside the tobacco box after sampling and difficulty in closing the box lid. Furthermore, manual hand-held operation is time-consuming and labor-intensive, and the efficiency and quality of sampling cannot be guaranteed, making it difficult to meet the quality control requirements of large-scale sampling. Utility Model Content

[0004] The purpose of this invention is to provide a packaging and sampling mechanism that can achieve efficient and accurate sampling, ensure the integrity of tobacco leaves, and ensure quality control during large-scale sampling.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A packaging and sampling mechanism is disposed on a conveyor roller conveyor for conveying tobacco boxes containing tobacco leaves. The packaging and sampling mechanism includes:

[0007] A support frame is erected on the conveyor roller conveyor;

[0008] The pressing assembly includes a first lifting drive and a packing pressure plate. The first lifting drive is disposed on the support frame and located above the conveyor roller. The packing pressure plate is drivenly connected to the pressing output shaft of the first lifting drive. The packing pressure plate is provided with a sampling hole.

[0009] The sampling assembly includes a second lifting drive and a sampling tube. The second lifting drive is disposed on the support frame corresponding to the sampling hole. The first end of the sampling tube is detachably connected to the sampling output shaft of the second lifting drive, and the second end of the sampling tube can be inserted into the sampling hole.

[0010] As a further technical solution, one of the sampling output shaft and the first end of the sampling tube is provided with a retaining shaft, and the other is provided with a connecting limiting groove. There are at least two retaining shafts, and the connecting limiting grooves are provided one-to-one with the multiple retaining shafts, and the multiple retaining shafts can be correspondingly limited and engaged with the multiple connecting limiting grooves.

[0011] As a further technical solution, the sampling assembly also includes a limiting flange, which is fixedly disposed on the sampling tube and located near the first end of the sampling tube.

[0012] As a further technical solution, the sampling component also includes a platform, which is fixedly disposed on one side of the support frame, and the platform is provided with a storage groove for accommodating the sampling tube.

[0013] As a further technical solution, the packaging sampling mechanism also includes a sample ejection component, which includes a sample ejection rod that is movably disposed above the storage slot and can be inserted into the sampling tube.

[0014] As a further technical solution, the sample ejection assembly also includes a sample ejection cylinder and a mounting component. The sample ejection cylinder is disposed above the platform via the mounting component. The output shaft of the sample ejection cylinder serves as the sample ejection rod, and the output shaft of the sample ejection cylinder extends and retracts in the vertical direction.

[0015] As a further technical solution, the clamping assembly also includes a plurality of reinforcing ribs, which are spaced apart on the upper end surface of the packing pressure plate.

[0016] As a further technical solution, an oil tank is also provided on the support frame, and a hydraulic pump assembly is provided on the oil tank;

[0017] Both the first lifting drive component and the second lifting drive component are hydraulic cylinders, and both are connected to the oil tank through oil supply pipes.

[0018] As a further technical solution, the support frame is configured as a gantry frame, and the center of the gantry frame coincides with the center of the conveyor roller conveyor in the front-back direction.

[0019] As a further technical solution, the packaging sampling mechanism also includes a sensing component, which is disposed on the conveyor roller corresponding to the support frame and is communicatively connected to both the first lifting drive and the second lowering drive.

[0020] Compared with the prior art, the packaging and sampling mechanism provided by this utility model has the following technical advantages:

[0021] Because the conveyor roller conveyor is equipped with a support frame, and the support frame is equipped with pressing and sampling components, when it is necessary to sample the tobacco leaves, the tobacco box containing the tobacco leaves is placed on the conveyor roller conveyor. The operation of the conveyor roller conveyor transports the tobacco box containing the tobacco leaves to below the support frame. The pressing output shaft of the first lifting drive extends downward to drive the packing plate to move downward until the packing plate presses the tobacco leaves in the tobacco box. At the same time, the sampling output shaft of the second lifting drive extends downward to drive the sampling tube connected to the sampling output shaft to move downward. As the sampling output shaft continues to extend, the second end of the sampling tube is inserted into the sampling hole and continues to move downward, so that the tobacco leaves in the tobacco box are pressed into the second end of the sampling tube. Then, both the pressing output shaft and the sampling output shaft retract upward until the packing plate and the sampling tube move upward and are completely separated from the tobacco leaves in the tobacco box, thus completing one sampling operation. Afterward, the conveyor roller conveyor runs again to transport the sampled tobacco leaves to the next station. Throughout the sampling process, on the one hand, sampling can be completed without prying open the surface of the tobacco leaves inside the tobacco box, thus avoiding damage to the compressed state of the tobacco leaves inside the box. At the same time, the tobacco leaves inside the tobacco box are pressed tightly by the packing plate to ensure the integrity of the tobacco leaves and prevent the tobacco leaves from becoming loose after sampling, which would make it difficult to close the tobacco box. On the other hand, during the sampling process, the distance that the second end of the sampling tube extends into the inside of the tobacco leaves, as well as the sampling frequency of the sampling tube, are controlled by the second lifting drive component. This eliminates the problem of inconsistent sampling quality caused by individual differences during manual sampling, thereby ensuring sampling quality and achieving efficient and accurate sampling. At the same time, since the second lifting drive component can operate continuously for a long time, it can meet the needs of large-scale sampling and ensure sampling efficiency and quality during large-scale sampling.

[0035] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0036] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0037] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0038] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0039] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0040] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0041] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0042] Combination Figures 1 to 4As shown, the packaging and sampling mechanism provided in this embodiment is set on the conveyor roller 10. The conveyor roller 10 is used to transport the tobacco box 20 containing tobacco leaves. This packaging and sampling mechanism can achieve efficient and accurate sampling, ensure the integrity of tobacco leaves, and ensure quality control during large-scale sampling. Specifically, the packaging and sampling mechanism includes a support frame 100, a pressing assembly, and a sampling assembly: the support frame 100 is mounted on the conveyor roller conveyor 10; the pressing assembly includes a first lifting drive 210 and a packaging pressure plate 220, the first lifting drive 210 is mounted on the support frame 100 and located above the conveyor roller conveyor 10, the packaging pressure plate 220 is drivenly connected to the pressing output shaft of the first lifting drive 210, and a sampling hole 221 is provided on the packaging pressure plate 220; the sampling assembly includes a second lifting drive 310 and a sampling tube 320, the second lifting drive 310 is correspondingly mounted on the support frame 100 with respect to the sampling hole 221, the first end of the sampling tube 320 is detachably connected to the sampling output shaft of the second lifting drive 310, and the second end of the sampling tube 320 can be inserted into the sampling hole 221.

[0043] Because a support frame 100 is provided on the conveyor roller 10, and a pressing component and a sampling component are provided on the support frame 100, when it is necessary to sample the tobacco leaves, the tobacco box 20 containing the tobacco leaves is placed on the conveyor roller 10; the operation of the conveyor roller 10 transports the tobacco box 20 containing the tobacco leaves to below the support frame 100, the pressing output shaft of the first lifting drive 210 extends downward to drive the packing pressure plate 220 to move downward until the packing pressure plate 220 presses the tobacco leaves in the tobacco box 20; at the same time, the sampling output shaft of the second lifting drive 310 extends downward to drive the sampling tube 3 connected to the sampling output shaft. As the sampling output shaft extends downwards, the second end of the sampling tube 320 is inserted into the sampling hole 221 and continues to move downwards, so that the tobacco leaves in the tobacco box 20 are pressed into the second end of the sampling tube 320. Then, both the pressing output shaft and the sampling output shaft retract upwards until the packing plate 220 and the sampling tube 320 move upwards and are completely separated from the tobacco leaves in the tobacco box 20, thus completing one sampling operation. After that, the conveyor roller 10 runs again to transport the sampled tobacco leaves to the next station. Throughout the sampling process, on the one hand, sampling can be completed without prying open the surface of the tobacco leaves inside the tobacco box 20, thus avoiding damage to the compressed state of the tobacco leaves inside the tobacco box 20. At the same time, the tobacco leaves inside the tobacco box 20 are pressed tightly by the packing plate 220 to ensure the integrity of the tobacco leaves and prevent the tobacco leaves from becoming loose after sampling, which would make it difficult to close the tobacco box 20. On the other hand, during the sampling process, the distance that the second end of the sampling tube 320 extends into the inside of the tobacco leaves, as well as the sampling frequency of the sampling tube 320, are controlled by the second lifting drive component 310. This eliminates the problem of inconsistent sampling quality caused by individual differences during manual sampling, thereby ensuring sampling quality and achieving efficient and accurate sampling. At the same time, since the second lifting drive component 310 can operate continuously for a long time, it can meet the needs of large-scale sampling and ensure sampling efficiency and quality during large-scale sampling.

[0044] The packaging and sampling mechanism provided in this embodiment not only completes the sampling work and ensures the integrity of the tobacco leaves during the sampling process, avoiding the situation where the tobacco leaves become loose after sampling, making it difficult to close the tobacco box 20, but also performs secondary packaging work.

[0045] Since the sampling tube 320 is detachably connected to the sampling output shaft in this embodiment, it can be connected to the output shaft when sampling is required to ensure sampling effectiveness. After sampling, the sampling tube 320 can be removed to facilitate the removal of the tobacco leaf sample pressed into the second end of the tube. Simultaneously, during the secondary packaging process, the sampling tube 320 can be detached from the sampling output shaft to ensure operational convenience during the secondary packaging process.

[0046] Specifically, in the previous pre-compression and packaging stage, the packaging equipment compacts the tobacco leaves in the tobacco box 20 for the first time. However, after compaction, some tobacco leaves still bounce loosely and exceed the height of the tobacco box 20. The tobacco box 20, now fully packaged, is then placed back on the conveyor roller conveyor 10. As the conveyor roller conveyor 10 rotates, the tobacco box 20 containing the tobacco leaves is transported to below the support frame 100. The pressing output shaft of the first lifting drive component 210 extends downwards to move the packaging pressure plate 220 downwards, performing a second compaction on the tobacco leaves after the first compaction, until the packaging pressure plate 220 tightly presses the tobacco leaves inside the tobacco box 20. Then, the pressing output shaft retracts upwards until the packaging pressure plate 220 is completely detached from the tobacco leaves inside the tobacco box 20. The conveyor roller conveyor 10 then rotates again to transport the second-compacted tobacco leaves to the next workstation. During this process, the second lifting drive component 310 and the sampling tube 320 do not participate in the operation.

[0047] Preferably, of the two, the sampling output shaft and the first end of the sampling tube 320, one is provided with a retaining shaft 211 and the other is provided with a connecting limiting groove 322. There are at least two retaining shafts 211, and the connecting limiting groove 322 is provided in a one-to-one correspondence with the multiple retaining shafts 211, and the multiple retaining shafts 211 can be correspondingly limited and engaged in the multiple connecting limiting grooves 322.

[0048] Combination Figure 4 As shown, in this embodiment, the sampling output shaft is provided with two retaining shafts 211, which are arranged opposite to each other and extend radially along the sampling output shaft. The first end of the sampling tube 320 is provided with two connecting limiting slots 322, which are both set as "L"-shaped or "⊥"-shaped slots. The diameter of the sampling output shaft is slightly smaller than the inner diameter of the sampling tube 320. During sampling, the sampling output shaft is inserted into the first end of the sampling tube 320, and the two retaining shafts 211 are positioned in the vertical slots of the two connecting limiting slots 322. Then, the sampling tube 320 is rotated so that the two retaining shafts 211 are positioned in the horizontal slots of the two connecting limiting slots 322, thereby connecting the sampling tube 320 to the sampling output shaft. When sampling is completed and the sampling tube 320 needs to be removed, it can be rotated in the opposite direction. This configuration ensures the stability of the connection between the sampling tube 320 and the sampling output shaft while improving the ease of assembly and disassembly of the sampling tube 320.

[0049] In some other embodiments, the first end of the sampling tube 320 can be directly threaded to the sampling output shaft, or it can be connected to the sampling output shaft by means of a threaded connector and a connecting flange.

[0050] Furthermore, the sampling assembly also includes a limiting flange 330, which is fixedly installed on the sampling tube 320 and located near the first end of the sampling tube 320. During the sampling process, when the sampling tube 320 moves downward, it abuts against the packing pressure plate 220 through the limiting flange 330, which can limit the maximum downward movement distance of the sampling tube 320 and prevent damage to the cigarette box 20 or the conveyor roller 10 due to excessive downward movement of the sampling tube 320.

[0051] Preferably, the sampling assembly further includes a platform 340, which is fixedly disposed on one side of the support frame 100, and the platform 340 is provided with a storage groove 341 for accommodating the sampling tube 320.

[0052] Combination Figure 1 , Figure 2 and Figure 4 As shown, after the sampling tube 320 has finished sampling, the second end of the sampling tube 320 is inserted into the storage slot 341. Then, the limiting flange 330 cooperates with the storage platform 340 to limit the relative position of the sampling tube 320 and the storage platform 340, thereby realizing the storage of the sampling tube 320 and avoiding damage to the sampling tube 320 caused by collisions between other components and the sampling tube 320. At the same time, by placing the sampling tube 320 in a fixed position, it is convenient for the operator to take it out and put it into the next use.

[0053] Preferably, the packaging sampling mechanism further includes a sample ejection component 400, which includes a sample ejection rod 410. The sample ejection rod 410 is movably disposed above the storage slot 341 and can be inserted into the sampling tube 320.

[0054] After sampling is completed, the sampling tube 320 containing the tobacco leaf sample is placed on the platform 340. Then, the ejection rod 410 is inserted into the sampling tube 320 from the first end and continuously pushed downwards until the tobacco leaf sample in the sampling tube 320 is ejected. The tobacco leaf sample is then collected, and the sampling tube 320, after ejection, is used for the next sampling operation. This method not only improves the convenience of sampling but also ensures that all the tobacco leaf sample in the sampling tube 320 is ejected, avoiding sample confusion in the next sampling process due to tobacco leaf residue in the sampling tube 320, thus ensuring the quality of the sample.

[0055] Furthermore, the sample ejection assembly 400 also includes a sample ejection cylinder 420 and a mounting component 430. The sample ejection cylinder 420 is mounted above the platform 340 via the mounting component 430. The output shaft of the sample ejection cylinder 420 serves as the sample ejection rod 410, and the output shaft of the sample ejection cylinder 420 extends and retracts in the vertical direction.

[0056] Combination Figure 1 and Figure 2 As shown, with this setup, during sample removal, the sampling tube 320 containing the tobacco leaf sample is placed on the platform 340, and then the sample removal cylinder 420 is activated. The output shaft of the sample removal cylinder 420 extends downward and is inserted into the first end of the sampling tube 320. As the output shaft of the sample removal cylinder 420 continues to extend downward, the automated sample removal is completed, thereby ensuring the convenience and efficiency of sample removal.

[0057] The pressing output shaft is connected to the middle of the packing pressure plate 220. This ensures that when the packing pressure plate 220 presses the tobacco leaves inside the tobacco box 20, the pressing force received by the tobacco leaves throughout the tobacco box 20 is approximately the same, thus guaranteeing a good pressing effect. To prevent the packing pressure plate 220 from folding upwards under the action of the contact force during the pressing process, this embodiment also includes multiple reinforcing ribs, which are spaced apart on the upper surface of the packing pressure plate 220.

[0058] Preferably, the support frame 100 is also provided with an oil tank 500, and the oil tank 500 is provided with a hydraulic pump assembly 600; the first lifting drive component 210 and the second lifting drive component 310 are both set as hydraulic cylinders and are connected to the oil tank 500 through the oil supply pipe 510. The oil tank 500 is provided with a hydraulic pump assembly 600, which includes a delivery pump and a delivery motor. When the delivery motor is running, the delivery pump delivers the hydraulic oil in the oil tank 500 to the first lifting drive component 210 and the second lifting drive component 310 through the oil supply pipe 510 to ensure the normal operation of the packaging pressure plate 220 and the sampling tube 320.

[0059] In some other embodiments, the oil tank 500 and the hydraulic pump assembly 600 may be omitted, and the first lifting drive component 210 and the second lifting drive component 310 may be directly set as lifting motors, not limited to the hydraulic cylinder in this embodiment.

[0060] To enhance the load-bearing capacity and stability of the compaction and sampling components, in this embodiment, the support frame 100 is configured as a gantry frame, which is fixed to the ground by anchor bolts. To further improve the stability of the compaction and sampling components during the sampling process or secondary compaction, the center of the gantry frame coincides with the center of the conveyor roller conveyor 10 in the front-to-back direction.

[0061] Preferably, the packaging and sampling mechanism further includes a sensing component (not shown in the figure). The sensing component is disposed on the conveyor roller 10 corresponding to the support frame 100, and is communicatively connected to the first lifting drive 210 and the second lowering drive. The sensing component includes a weight sensor, a position sensor, or a distance sensor. As the conveyor roller 10 rotates, when the sensing component senses that the tobacco box 20 has been conveyed to below the support frame 100, it transmits an operating signal to the first lifting drive 210 and the second lowering drive. The first lifting drive 210 and the second lowering drive then begin to operate to achieve the pressing and sampling process of the tobacco leaves in the tobacco box 20, thereby realizing automated sampling.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
