Description

Technical Field

[0001] This utility model relates to the technical field of tobacco production equipment, specifically to an online detection device for the content of tobacco strands in tobacco shreds. Background Technology

[0002] In cigarette production, tobacco leaves undergo a threshing and stem-removal process to separate the leaves from the stems. Stem fragments refer to the separated stems, stem pieces, stem chunks, and any remaining broken stems. These are hard and have a much lower combustibility and flavor compared to shredded tobacco, and are usually considered a byproduct or waste. Shredded tobacco constitutes a major cost component of cigarettes. A high shredded tobacco content means significant raw material waste, leading to increased production costs.

[0003] Currently, most methods for detecting tobacco content are offline tests, which involve taking a certain amount of sample, weighing it, separating the tobacco shreds, weighing it again, and calculating the weight. This process is cumbersome and complicated, requiring the machine to be stopped for sampling, and the samples need to be sent to the laboratory for manual or equipment testing. It is time-consuming, cannot provide real-time guidance for production, and has poor practicality. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] See Figures 1-5 As shown, this utility model provides an online detection device for the fiber content of stems, including an outer box 1 and a digital display controller 10. The outer box 1 is rotatably connected inside a portal frame 2. A weighing cover plate 9 can be rotatably opened and closed at the upper opening of the outer box 1. A drive assembly 3 is provided on the portal frame 2 to drive the outer box 1 to rotate 180 degrees. Clamping assemblies 4 are provided at both lower ends of the portal frame 2 for connection with the production line. An inner box 7 is nested inside the outer box 1. A feed inlet 11 is opened on one side of the lower end of the inner box 7. A screening filter screen 15 is fixedly connected to the upper end of the inner box 7. A discharge outlet 12 is opened at the bottom of the inner box 7. A weighing cover plate 13 can be rotatably opened and closed at the discharge outlet 12. An electric push rod 8 is provided on the side wall of the outer box 1 to drive the inner box 7 to move. The input end of the electric push rod 8 is electrically connected to the output end of the digital display controller 10.

[0028] As an optional implementation, the side wall of the outer casing 1 is opened and closed by a push-pull structure 5 symmetrically supporting the weighing cover 9. The push-pull structure 5 includes an electric push rod 501 fixedly installed on the side wall of the outer casing 1. The movable end of the electric push rod 501 is fixedly connected to a U-shaped frame 502, and the open end of the U-shaped frame 502 is fixedly connected to a fixing rod 503. A ring 504 is fixedly connected to the outside of the fixing rod 503 on the weighing cover 9. The input end of the electric push rod 501 is electrically connected to the output end of the digital display controller 10. When it is necessary to discharge the tobacco from the surface of the weighing cover 9, the extension of the electric push rod 501 can drive the weighing cover 9 to rotate and open at the opening of the outer casing 1, so that the fixing rod 503 moves in the ring 504, and the tobacco falls down the slope and is discharged under the action of gravity.

[0029] As an optional implementation, the drive assembly 3 includes an electric push rod 303 fixedly mounted on the portal frame 2. The movable end of the electric push rod 303 is fixedly connected to a rack 302. The rotating shaft of the outer casing 1 extends to the outside of the portal frame 2 and is fixedly connected to a gear 301 that meshes with the rack 302. The input end of the electric push rod 303 is electrically connected to the output end of the digital display controller 10. By extending and retracting the electric push rod 303, the rack 302 can be moved. As the rack 302 moves, the meshing gear 301 can be rotated, thereby causing the outer casing 1 to rotate 180 degrees inside the portal frame 2. To prevent the rack 302 from misaligning with the gear 301 under force, a limiting sleeve (not shown in the figure) can be fixedly fitted on the surface of the portal frame 2 on the outside of the rack 302, which can effectively prevent the rack 302 from shifting or misaligning. It is also worth mentioning that drive assemblies 3 can be set on both sides of the portal frame 2 to ensure the stable rotation of the outer casing 1 and related components.

[0030] Reference Figure 3 As shown, the clamping assembly 4 includes an L-shaped plate 401 fixedly connected to the lower end of the gantry frame 2. An ear plate 402 is fixedly connected to the horizontal part of the L-shaped plate 401. A bolt 403 is threadedly connected to the ear plate 402 through a bolt hole. The end of the bolt 403 is rotatably connected to a clamping plate 404 that cooperates with the vertical part of the L-shaped plate 401. After the L-shaped plate 401 is placed on the baffles on both sides of the production line, rotating the bolt 403 can drive the clamping plate 404 to move closer to the vertical part of the L-shaped plate 401 until it is clamped and fixed.

[0031] Specifically, the bottom plate at the feed inlet 11 is designed with a slope. Electronic weighing devices are installed on both the weighing cover plate 11 and the weighing cover plate 213. The input end of the electronic weighing device is electrically connected to the output end of the digital display controller 10. The sloped feed inlet 11 allows the material to enter the surface of the weighing cover plate 213 more smoothly when scooping up the stem material. At the same time, the electronic weighing device adopts a resistance strain gauge sensor with a weighing accuracy of not less than 0.001g. The weighing data can be transmitted to the digital display controller 10, and the filament content of the stem can be obtained through its calculation. The calculation formula for this data can be implemented by simple programming by those skilled in the art, and the calculation method will not be described in detail here.

[0032] As an optional implementation, the inner wall of the inner box 7 is opened and closed by a push-pull structure 26 symmetrically weighing the cover plate 2 13. The push-pull structure 26 includes an electric push rod 4 601 fixedly installed on the inner wall of the inner box 7. The movable end of the electric push rod 4 601 is fixedly connected to a U-shaped frame 2 603. The open end of the U-shaped frame 2 603 is fixedly connected to a fixing rod 2 604. A ring 2 602 sleeved on the outside of the fixing rod 2 604 is fixedly connected to the weighing cover plate 2 13. The input end of the electric push rod 4 601 is electrically connected to the output end of the digital display controller 10. When it is necessary to discharge the sticks on the surface of the weighing cover plate 2 13, the electric push rod 4 601 is extended to drive the weighing cover plate 2 13 to rotate and open at the discharge port 12, so that the fixing rod 2 604 moves in the ring 2 602. The sticks fall down the slope and are discharged under the action of gravity.

[0033] Reference Figure 4 As shown, a movable groove 17 is provided on the side wall of the outer casing 1. A T-shaped slider 18 is fixedly connected to the inner casing 7 and slidably connected thereto. The movable end of the electric push rod 8 is connected to the T-shaped slider 18. A vibration motor 16 is fixedly installed on the inner wall of the inner casing 7. The T-shaped slider 18 is provided with an elastic connector for amplifying the vibration. The elastic connector includes a rectangular frame 19 sleeved on the outside of the T-shaped slider 18. Springs 14 are connected to the T-shaped slider 18 at both ends of the inner side of the rectangular frame 19. The movable end of the electric push rod 8 is fixedly connected to the side wall of the rectangular frame 19. The movable groove 17 allows the electric push rod 8 to extend and retract. The rectangular frame 19 and spring 14 drive the T-shaped slider 18 to move stably in the movable groove 17. The T-shaped slider 18 can prevent the rectangular frame 19 from shaking significantly on its outside. When the vibration motor 16 generates vibration, it can transmit the vibration to the T-shaped slider 18. The T-shaped slider 18 is connected to two springs 14. The springs 14 can amplify the vibration generated on the surface of the screening screen 15, so that the stems on the screen surface are evenly distributed on the screen surface, avoiding accumulation and making full use of the screen surface area. At the same time, the vibration allows smaller tobacco shreds to have more opportunities to fall through the screen holes onto the surface of the weighing cover plate 9.

[0034] Specifically, the gap fit between the inner box 7 and the inner wall of the outer box 1 makes the inner box 7 more stable when it moves, while preventing the stems and tobacco from getting stuck in the gap between them.

[0035] The working principle of this utility model:

[0036] In use, two L-shaped plates 401 are placed on the stem production line and clamped and fixed by rotating bolts 403 to drive clamping plates 404. When testing is required, the electric push rod 8 is controlled to move the inner box 7 downward. At this time, the feed inlet 11 comes into contact with the surface of the stem conveyor belt. A portion of the stems enter the surface of the weighing cover plate 13 through the ramp at the feed inlet 11. The electronic weighing device on its surface is used for weighing and the data is uploaded to the digital display controller 10. Then, the electric push rod 303 drives the rack 302 downward. The rack 302 meshes with the gear 301, thereby causing the outer box 1 and the inner box 7 to rotate 180 degrees inside the gantry frame 2. At this time, the stems fall off. When the tobacco leaves reach the surface of the sieve filter 15, the vibration motor 16 is turned on. The vibration generated by the motor is amplified by two springs 14, which makes the tobacco leaves evenly distributed on the sieve surface, avoiding accumulation and making full use of the sieve surface area. At the same time, the vibration allows smaller tobacco leaves to fall through the sieve holes onto the surface of the weighing cover 9. After the vibration stops, the electronic weighing device on the weighing cover 9 is used to weigh the tobacco leaves and upload the data to the digital display controller 10. The digital display controller 10 automatically calculates and displays the tobacco leaf content data. After the test is completed, the weighing cover 9 and the second weighing cover 13 are opened to discharge and collect the tobacco leaves and tobacco leaves.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
