Description

Technical Field

[0001] This utility model relates to the field of conveying accessories, and more specifically, to a filter rod conveying structure. Background Technology

[0002] A filter rod is a filtering component used in tobacco products. It is a rod-shaped object made of fiber bundles and special adhesives. The inside of the filter rod can be filled with various materials, such as activated carbon and ceramic balls, which are mainly used to reduce the inhalation of harmful substances in tobacco and protect the health of smokers.

[0003] Currently, during the production of filter rods, operators need to extract samples from the same batch of filter rods for near-infrared spectroscopy to quickly determine the composition and content of each substance in that batch. However, the filter rod conveying structures currently used for conveying filter rods are quite complex. Furthermore, during near-infrared scanning, it is either difficult to ensure that the entire filter rod is scanned by near-infrared light, or it is difficult to ensure that the gaps between adjacent filter rods are not scanned. Therefore, it is necessary to propose a filter rod conveying structure that solves the above problems. Utility Model Content

[0004] To overcome at least one of the defects (deficiencies) of the prior art described above, this utility model provides a filter rod conveying structure.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a filter rod conveying structure, including a mounting and fixing plate, a filter rod conveying limiting block, and a first conveyor and a second conveyor for introducing filter rods;

[0006] The filter rod conveying limit block is set on the mounting plate, and the first conveyor and the second conveyor are respectively set on the mounting plate below the filter rod conveying limit block. The inner side of the filter rod conveying limit block and the outer sides of the first conveyor and the second conveyor form the filter rod conveying channel.

[0007] The filter rod conveying limit block is equipped with a detection sensor for detecting the filter rod's position. The detection sensor, the first conveyor, and the second conveyor are connected via a control chip. By placing the filter rod conveying limit block on a mounting plate above the first and second conveyors, the inner side of the filter rod conveying limit block and the outer sides of the first and second conveyors form a filter rod conveying channel. This facilitates the conveying of the filter rod and simplifies the structure. To enable intelligent control of the filter rod's conveying and detection, a detection sensor is provided on the filter rod conveying limit block to detect whether the filter rod has moved to the correct position. The detection sensor can intelligently control the start and stop of the first conveyor, the second conveyor, and the near-infrared detector, ensuring that the near-infrared detector can scan the entire filter rod completely without scanning the gaps between adjacent filter rods, thus making the near-infrared detector's detection results more accurate.

[0008] Furthermore, the first conveyor is equipped with a filter rod conveying drive motor, and the first conveyor and the second conveyor are connected by a linkage. The filter rod conveying drive motor is connected to a control chip. Since the first conveyor and the second conveyor are driven by a linkage, only one filter rod conveying drive motor is needed to drive the first conveyor and the second conveyor, which is simple and practical.

[0009] Furthermore, the first conveyor includes a first drive wheel, a second drive wheel, and a first drive belt, and the second conveyor includes a third drive wheel, a fourth drive wheel, and a second drive belt;

[0010] The filter rod conveying drive motor is connected to the first transmission wheel, the first transmission belt is sleeved between the first transmission wheel and the second transmission wheel, and the second transmission belt is sleeved between the third transmission wheel and the fourth transmission wheel;

[0011] The second and third transmission wheels are connected by a linkage. Since the filter rod conveying drive motor is connected to the first transmission wheel and the linkage is located between the second and third transmission wheels, only one filter rod conveying drive motor is needed to achieve synchronous drive of the first and second conveyors.

[0012] Furthermore, the first, second, third, and fourth transmission wheels are all positioned at the same height on the mounting plate. Since the first, second, third, and fourth transmission wheels are all positioned at the same height, it facilitates the conveying of the filter rods.

[0013] Furthermore, the linkage includes a first linkage shaft, a second linkage shaft, a first linkage wheel, a second linkage wheel, and a linkage belt;

[0014] The mounting plate has a connecting hole. One end of the first linkage shaft is connected to the second transmission wheel, and the other end passes through the connecting hole of the mounting plate and is connected to the first linkage wheel. One end of the second linkage shaft is connected to the third transmission wheel, and the other end passes through the connecting hole of the mounting plate and is connected to the second linkage wheel. The linkage belt is sleeved on the outside of the first and second linkage wheels. The connecting hole on the mounting plate facilitates the passage of the first and second linkage shafts. With this arrangement, the linkage is located on the back of the mounting plate, while the first and second conveyors are arranged in sections on the front of the mounting plate, which facilitates near-infrared detection of the filter rod between the first and second conveyors.

[0015] Furthermore, the feed end of the filter rod conveying channel is funnel-shaped. By setting the feed end of the filter rod conveying channel to a funnel shape, the filter rod can be flattened, thereby increasing the contact area between the filter rod and near-infrared light during near-infrared light detection.

[0016] Furthermore, the feed end of the filter rod conveying channel is provided with a flattening block for flattening the filter rod. By setting the flattening block, the filter rod can also be flattened, thereby increasing the contact area between the filter rod and near-infrared light during near-infrared light detection.

[0017] Furthermore, the filter rod conveying limiting block includes a limiting pressing block, a limiting support block, a first side stop block, and a second side stop block;

[0018] One end of the limiting support block is set on the mounting plate, and the other end passes through the middle of the first conveyor and the second conveyor;

[0019] The first side block and the second side block are respectively arranged on both sides of the limiting support block along the direction of the filter rod introduction;

[0020] The limiting lower pressure block presses against the first side block and the second side block, so that the inner surfaces of the limiting lower pressure block, the first side block and the second side block, together with the outer surfaces of the first transmission belt and the second transmission belt, form a filter rod conveying channel. The limiting support block can support the limiting lower pressure block, the first side block and the second side block. The inner surfaces of the limiting lower pressure block, the first side block and the second side block, together with the outer surfaces of the first transmission belt and the second transmission belt, form a filter rod conveying channel. The filter rod can be set on the first transmission belt and the second transmission belt by its own weight, and the filter rod is conveyed under the drive of the first transmission belt and the second transmission belt.

[0021] Furthermore, the detection sensor is a diffuse reflection phototube. In practical applications, other devices or sensors can also be used to replace the detection sensor, which are all alternative solutions that are easy for those skilled in the art to conceive of.

[0022] Furthermore, there is at least one diffuse reflection phototube. In practical applications, multiple diffuse reflection phototubes can be set on the filter rod conveying limit block as needed to detect the conveying position of the filter rod.

[0023] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0024] The filter rod conveying structure disclosed in this utility model sets a filter rod conveying limiting block on a mounting plate above the first and second conveyors. This forms a filter rod conveying channel with the inner side of the limiting block and the outer sides of the first and second conveyors, facilitating filter rod conveying and simplifying the structure. For intelligent control of filter rod conveying and detection, a detection sensor is provided on the limiting block to detect whether the filter rod has moved to the correct position. This sensor intelligently controls the start and stop of the first and second conveyors and the near-infrared detector, ensuring that the near-infrared detector can scan the entire filter rod without missing the gaps between adjacent filter rods, thus making the detection results more accurate.

[0032] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0034] like Figure 1-2As shown, a filter rod conveying structure includes a mounting plate 1, a filter rod conveying limiting block 2, and a first conveyor 4 and a second conveyor 5 for guiding filter rods 3. The filter rod conveying limiting block 2 is mounted on the mounting plate 1, and the first conveyor 4 and the second conveyor 5 are respectively mounted on the mounting plate 1 below the filter rod conveying limiting block 2. The inner side of the filter rod conveying limiting block 2 and the outer sides of the first conveyor 4 and the second conveyor 5 form a filter rod conveying channel 6. A detection sensor 7 for detecting the arrival of the filter rod 3 is provided on the filter rod conveying limiting block 2. The detection sensor 7, the first conveyor 4, and the second conveyor 5 are connected by a control chip 11. By setting the filter rod conveying limiting block 2 on the first conveyor 4 and the second conveyor 5, the filter rod conveying channel 6 can be constructed. The filter rod is mounted on the mounting plate 1 above the device 5, so the inner side of the filter rod conveying limit block 2 and the outer side of the first conveyor 4 and the second conveyor 5 form the filter rod conveying channel 6, which facilitates the conveying of the filter rod 3 and simplifies the structure. In order to intelligently control the conveying and detection of the filter rod 3, a detection sensor 7 is provided on the filter rod conveying limit block 2 to detect whether the filter rod 3 has moved to the correct position. The detection sensor 7 can intelligently control the start and stop of the first conveyor 4, the second conveyor 5 and the near-infrared detector 8, thereby ensuring that the near-infrared detector 8 can scan the entire filter rod completely without scanning the gap between adjacent filter rods 3, making the detection results of the near-infrared detector more accurate.

[0035] like Figure 3-4As shown, the first conveyor 4 is equipped with a filter rod conveying drive motor 9. The first conveyor 4 and the second conveyor 5 are connected by a linkage 10. The filter rod conveying drive motor 9 is connected to a control chip 11. Since the first conveyor 4 and the second conveyor 5 are driven by the linkage 10, only one filter rod conveying drive motor 9 is needed to drive the first conveyor 4 and the second conveyor 5, which is simple and practical. The first conveyor 4 includes a first transmission wheel 12, a second transmission wheel 13, and a first transmission belt 14. The second conveyor 5 includes a third transmission wheel 15, a fourth transmission wheel 16, and a second transmission belt 17. The filter rod conveying drive motor 9 is connected to the first transmission wheel 12, and the first transmission belt 14 is sleeved between the first transmission wheel 12 and the second transmission wheel 13. The second transmission belt 17 is sleeved between the third transmission wheel 15 and the fourth transmission wheel 16; the second transmission wheel 13 and the third transmission wheel 15 are connected by a linkage 10. Since the filter rod conveying drive motor 9 is connected to the first transmission wheel 12 and the linkage 10 is set between the second transmission wheel 13 and the third transmission wheel 15, only one filter rod conveying drive motor 9 is needed to achieve synchronous drive of the first conveyor 4 and the second conveyor 5. In this utility model, the first transmission wheel 12, the second transmission wheel 13, the third transmission wheel 15, and the fourth transmission wheel 16 are set at the same height on the mounting plate 1. Since the first transmission wheel 12, the second transmission wheel 13, the third transmission wheel 15, and the fourth transmission wheel 16 are all set at the same height, it is convenient to convey the filter rod 3.

[0036] In this utility model, the linkage 10 includes a first linkage shaft 18, a second linkage shaft 19, a first linkage wheel 20, a second linkage wheel 21, and a linkage belt 22. The mounting plate 1 is provided with a connecting hole 23. One end of the first linkage shaft 20 is connected to the second transmission wheel 13, and the other end passes through the connecting hole 23 of the mounting plate 1 and is connected to the first linkage wheel 20. One end of the second linkage shaft 19 is connected to the third transmission wheel 15, and the other end passes through the connecting hole 23 of the mounting plate 1 and is connected to the second linkage wheel 21. The linkage belt 22 is sleeved on the outside of the first linkage wheel 20 and the second linkage wheel 21. The connecting hole 23 on the mounting plate 1 facilitates the passage of the first linkage shaft 18 and the second linkage shaft 19. With this arrangement, the linkage 10 is located on the back of the mounting plate 1, while the first conveyor 4 and the second conveyor 5 are arranged in sections on the front of the mounting plate 1, which facilitates near-infrared detection of the filter rod 3 between the first conveyor 4 and the second conveyor 5.

[0037] like Figure 5-6As shown, the feed end of the filter rod conveying channel 6 is funnel-shaped. By setting the feed end of the filter rod conveying channel 6 to a funnel shape, the filter rod 3 can be flattened, thereby increasing the contact area between the filter rod 3 and near-infrared light during near-infrared light detection. In addition, a flattening block for flattening the filter rod 3 can be provided at the feed end of the filter rod conveying channel 6. By setting the flattening block, the filter rod can also be flattened, thereby increasing the contact area between the filter rod and near-infrared light during near-infrared light detection.

[0038] In this invention, the filter rod conveying limiting block 2 includes a limiting pressing block 24, a limiting support block 25, a first side stop 26, and a second side stop 27. One end of the limiting support block 25 is mounted on the mounting plate 1, and the other end passes through the middle of the first conveyor 4 and the second conveyor 5. The first side stop 26 and the second side stop 27 are respectively arranged on both sides of the limiting support block 25 along the direction in which the filter rod 3 is guided. The limiting pressing block 24 presses against the top of the first side stop 26 and the second side stop 27, so that the inner surfaces of the limiting pressing block 24, the first side stop 26, and the second side stop 27, together with the outer surfaces of the first transmission belt 14 and the second transmission belt 17, form the filter rod conveying channel 6. The limiting support block 25 provides support for the limiting pressing block 24, the first side stop 26, and the second side stop 27. The inner surfaces of the limiting pressure block 24, the first side stop block 26, and the second side stop block 27, together with the outer surfaces of the first transmission belt 14 and the second transmission belt 17, form the filter rod conveying channel 6. The filter rod 3 can be set on the first transmission belt 14 and the second transmission belt 17 by its own weight, and is conveyed by the first transmission belt 14 and the second transmission belt 17. The detection sensor 7 is a diffuse reflection phototube. In practical applications, the detection sensor 7 can also be replaced by other devices or sensors, which are all alternatives that are easy for those skilled in the art to think of. In this utility model, there is at least one diffuse reflection phototube. In practical applications, multiple diffuse reflection phototubes can be set on the filter rod conveying limiting block 2 as needed to detect the conveying position of the filter rod 3.

[0039] Example

[0040] In this embodiment, during installation, the filter rod conveying limit block is set on the mounting plate, and the first conveyor and the second conveyor are respectively set on the mounting plate below the filter rod conveying limit block, so that the inner side of the filter rod conveying limit block and the outer sides of the first and second conveyors form the filter rod conveying channel. This arrangement facilitates the conveying of the filter rod and simplifies the structure of the filter rod conveying channel, the first conveyor, and the second conveyor.

[0041] In this embodiment, a near-infrared detector is mounted on the mounting plate of the first and second conveyors, and the near-infrared detection head on the near-infrared detector is coplanar with the outer surface of the first and second conveyors. This allows the near-infrared detection head on the near-infrared detector to better detect the filter rods as they pass through the first and second conveyors. Since a metal background plate is needed to reflect the near-infrared light during near-infrared detection, this invention uses a linkage to allow the near-infrared detector and the metal background plate to be placed in front of the mounting plate of the first and second conveyors, thereby facilitating near-infrared detection of the filter rods.

[0042] To achieve intelligent control of the filter rod conveying and detection, a detection sensor is installed on the filter rod conveying limit block to detect whether the filter rod has moved to the correct position. This sensor controls the start and stop of the near-infrared detector and the filter rod conveying drive motor. Specifically, when the filter rod is placed at the feed end of the filter rod conveying channel, the first detection sensor at the feed end transmits a signal to the control chip. The control chip then drives the filter rod conveying drive motor to start, thus conveying the filter rod. As the filter rod passes through the trumpet-shaped feed end of the filter rod conveying channel, it is flattened. When the front end of the filter rod reaches the front end of the near-infrared detector, the corresponding second detection sensor... The signal is transmitted to the control chip, which drives the near-infrared detector to perform near-infrared detection based on the conveying speed of the filter rod. When the end of the filter rod reaches the front end of the near-infrared detector, the second detection sensor at the corresponding position transmits a signal to the control chip. The control chip sends a delayed stop scanning signal to the near-infrared detector, which ensures that the filter rod is completely scanned and does not scan the gaps between adjacent filter rods, making the detection results of the near-infrared detector more accurate. When the end of the filter rod reaches the end of the second conveyor, the third detection sensor at the end of the second conveyor transmits a signal to the control chip. The control chip sends a signal to the filter rod conveying drive motor, and the filter rod conveying drive motor stops rotating.

[0043] The positional relationships described in the figures are for illustrative purposes only and should not be construed as limiting this patent. Clearly, the above embodiments of this utility model are merely examples to clearly illustrate the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
