Description

Technical Field

[0001] The present invention relates to the technical field of cigarette detection, and specifically relates to a near-infrared detection sampling and metering device for cigarette filter rods. Background Technique

[0002] Increasing the application amount of triacetin in the filter rod can reduce the release amount of phenol in cigarette smoke. Therefore, controlling the application amount of triacetin in the filter rod helps to reduce the tar and harm of cigarette products.

[0003] Common detection methods for the application amount of triacetin in filter rods include: gas chromatography, gravimetry, and near-infrared method. The detection time of gas chromatography is relatively long, and the error of gravimetry is relatively large. Therefore, the most commonly used method is the near-infrared method.

[0004] However, in the process of using the near-infrared method, we still find the following defects: when detecting the filter rod, it is necessary to grab the filter rod. At present, the grabbing device cannot accurately count the number of filter rods. Therefore, there is an urgent need for a filter rod grabbing device that can accurately count.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-4, A near-infrared detection sampling and metering device for cigarette filter rods, comprising a mounting plate 1 and a collection cylinder 2. A reciprocating mechanism is installed inside the mounting plate 1, and the output end of the reciprocating mechanism is connected to the collection cylinder 2. The upper end of the collection cylinder 2 is flared. A partition plate 3 is fixedly connected inside the collection cylinder 2. A number of first channels 4 are evenly and equidistantly distributed on the partition plate 3. A moving plate 5 is connected below the partition plate 3 through an adjusting mechanism. Second channels 6 are provided at positions corresponding to the first channels 4 on the moving plate 5. The moving plate 5 passes through the collection cylinder 2 and is slidably connected to the collection cylinder 2. A number of counting cylinders 7 are fixedly connected at a position near the lower part inside the collection cylinder 2. The counting cylinders 7 are located directly below the first channels 4. When the device needs to be used, the filter rods are placed into the collection cylinder 2. Under the action of gravity, the filter rods are distributed above the first channels 4. Then, through the adjusting mechanism, the second channels 6 and the first channels 4 are completely aligned, enabling the filter rods to pass through the first channels 4 and the second channels 6 and then fall into the counting cylinders 7, so as to accurately count the filter rods.

[0026] The reciprocating mechanism includes a fixed slot 8, which is opened on the mounting plate 1 and penetrates through the mounting plate 1. The collection cylinder 2 passes through the fixed slot 8. Two sliding rod slots 9 are opened on the wall of the fixed slot 8. A sliding rod 10 is slidably connected inside the sliding rod slot 9. One end of the sliding rod 10 passes through the notch of the sliding rod slot 9 and extends outward, and is fixedly connected to the side wall of the collection cylinder 2. A support plate 11 is fixedly connected to the lower end of the mounting plate 1. A driving motor 12 is fixedly connected to the side wall of the support plate 11. A rotating disk 13 is fixedly connected to the output end of the driving motor 12. A push-pull rod 14 is hinged on the side wall of the rotating disk 13. The end of the push-pull rod 14 away from the rotating disk 13 is hinged on the outer side wall of the collection cylinder 2. When the filter rods are placed into the collection cylinder 2, the driving motor 12 is started. The driving motor 12 drives the rotating disk 13 to rotate. The rotating disk 13 drives the push-pull rod 14 to move, thereby driving the collection cylinder 2 to reciprocate, so that the filter rods in the collection cylinder 2 can be discharged neatly.

[0027] The adjusting mechanism includes a mounting frame 15 fixedly connected to the outside of the collection cylinder 2. An adjusting motor 16 is installed on the mounting frame 15. The output end of the adjusting motor 16 passes through the mounting frame 15 and is fixedly connected with a threaded sleeve 17. A screw rod 18 is threadedly connected inside the threaded sleeve 17. One end of the screw rod 18 passes through the opening of the threaded sleeve 17 and extends outward, and is fixedly connected to the side wall of the moving plate 5. When it is necessary to drive the moving plate 5 to move, the adjusting motor 16 is started. The adjusting motor 16 drives the threaded sleeve 17 to rotate. The threaded sleeve 17 drives the screw rod 18 to drive the moving plate 5 to move, so that the moving plate 5 drives the second channels 6 to move, enabling the second channels 6 and the first channels 4 to coincide.

[0028] Two symmetrically arranged stabilizing rods 19 are fixedly connected to the upper end of the mounting plate 1. The upper end of the stabilizing rod 19 is fixedly connected to a stabilizing sleeve 20. An auxiliary rod 21 is slidably connected within the stabilizing sleeve 20. The auxiliary rod 21 passes through the stabilizing sleeve 20 and is fixedly connected to the corresponding side wall of the collecting cylinder 2, making the movement of the collecting cylinder 2 more stable and reliable.

[0029] A limiting groove 22 is formed in the rod wall of the sliding rod 10. A limiting block 23 slidably connected thereto is arranged within the limiting groove 22. One end of the limiting block 23 passes through the notch of the limiting groove 22 and extends outward, and is fixedly connected to the groove wall within the sliding rod groove 9. A ball groove 24 is formed at the lower end of the limiting block 23. A ball 25 is rotatably connected within the ball groove 24. One end of the ball 25 passes through the notch of the ball groove 24 and extends outward, and is rotatably connected to the bottom of the limiting groove 22, making the movement of the limiting block 23 within the limiting groove 22 more stable, reliable and smooth.

[0030] Several guiding plates 26 are fixedly connected to the upper end of the partition plate 3. The several guiding plates 26 are respectively located between two adjacent first channels 4, playing a guiding role for the filter rods.

[0031] In summary, for the near-infrared detection sampling and metering device for cigarette filter rods, when the device needs to be used, the filter rods are placed into the collecting cylinder 2. Under the action of gravity, the filter rods are distributed above the first channels 4. Then, through the adjustment mechanism, the second channel 6 and the first channel 4 are completely overlapped, so that the filter rods pass through the first channel 4 and the second channel 6 and then fall into the counting cylinder 7, enabling accurate counting of the filter rods. When the filter rods are placed into the collecting cylinder 2, the driving motor 12 is started. The driving motor 12 drives the rotating disk 13 to rotate, and the rotating disk 13 drives the push-pull rod 14 to move, thereby driving the collecting cylinder 2 to reciprocate, making the filter rods in the collecting cylinder 2 discharged neatly.
