Description

Technical Field

[0001] This utility model relates to the field of tobacco processing equipment technology, and in particular to an auxiliary feeding device for a tobacco quantitative feeder. Background Technology

[0002] In cigarette production lines, a feeding system consisting of a feeder, a metering tube, and an electronic belt scale is often used to transport the cigarette tobacco. The feeder conveys the tobacco into the metering tube, where it falls onto the electronic belt scale. After being weighed and recorded by the electronic belt scale, the tobacco is then conveyed to the next conveyor belt. There is a vertical height difference between the electronic belt scale and the next conveyor belt.

[0003] Because of the mutual traction between the tobacco particles, ideally, if the belt of the electronic belt scale moves 1cm, the tobacco particles should exit the electronic belt scale by 1cm from the discharge end. However, in actual use, it has been found that the tobacco particles often do not exit smoothly and continuously under their own traction force. Usually, if the electronic belt scale moves 1cm, the tobacco particles extend 1cm from the discharge end of the electronic belt scale, but do not fall off under the mutual pulling force. Until the electronic belt scale moves 10cm, a large clump of tobacco particles falls off, causing the tobacco particles on the conveyor belt of the next process to be discontinuous, and "white spots" appear on the conveyor belt. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary feeding device for a tobacco quantitative feeder, which solves the problem in the prior art where the tobacco material on the conveyor belt in the next process after the electronic belt scale is discontinuous and the conveyor belt will show "white spots".

[0005] This utility model solves the above-mentioned technical problems through the following technical means:

[0006] An auxiliary feeding device for a tobacco quantitative feeder includes an intermediate conveying mechanism disposed between an electronic belt scale and a conveyor belt. The intermediate conveying mechanism includes a conveyor belt, a support frame, and a drive assembly. Several scraper blades are arranged circumferentially on the surface of the conveyor belt. When the scraper blades rotate to the top of the conveyor belt, they can scrape away the tobacco material extending from the discharge end of the electronic belt scale. The space between two adjacent scraper blades forms a temporary storage space for the scraped tobacco material. When the scraper blades rotate to the bottom of the conveyor belt, the tobacco material slides from the temporary storage space onto the conveyor belt.

[0007] The intermediate conveying mechanism is inclined from top to bottom along the direction away from the electronic belt scale. When the scraper moves to the side of the conveyor belt away from the electronic belt scale, the scraper is inclined from bottom to top along the direction away from the conveyor belt.

[0008] By setting up the above structure, the scraper can scrape away the smoke material extending from the discharge end of the electronic belt scale and temporarily store it in the storage space as the conveyor belt moves. As the electronic belt scale and the intermediate conveyor mechanism continue to operate, the smoke material continuously extends from the discharge end of the electronic belt scale and is scraped away by the scraper. When the scraper moves to the bottom of the intermediate conveyor mechanism, the smoke material in the storage space is automatically unloaded under its own gravity. The whole process is continuous, and the material on the conveyor belt is continuous and uniform, avoiding the occurrence of "exposed white material".

[0009] Furthermore, the scraper blade smoothly transitions with the drive belt on the side closest to the conveyor belt.

[0010] By setting up the above structure, when the scraper plate moves to the bottom of the intermediate conveyor mechanism, the smoke material in the temporary storage space can fall off naturally without getting stuck in the gap between the scraper plate and the conveyor belt.

[0011] Furthermore, an arc-shaped rake is provided on the side of the scraper away from the transmission belt.

[0012] By setting up the above structure, the smoke material extending from the discharge end of the electronic belt scale can be easily scraped away. At the same time, the pulling force of the scraped-away smoke material on the smoke material still on the electronic belt scale is insufficient to pull the smoke material on the electronic belt scale off, so that the amount of smoke material scraped away each time is constant, scraping is easy, and the continuity and uniformity of the smoke material on the conveyor belt are further guaranteed.

[0013] Furthermore, both ends of the scraper are provided with side plates.

[0014] By setting up the above structure, the smoke material in the temporary storage space will not fall from both ends of the scraper plate.

[0015] Furthermore, it also includes horizontally arranged slide rails, which are two rails symmetrically arranged on both sides of the conveyor belt. The length direction of the slide rails is parallel to the feeding direction of the electronic belt scale. Support legs are provided on the outside of the support frame, and the support legs are supported on the slide rails. A connecting rod is provided between the support legs. A telescopic component is provided on one side of the intermediate conveying mechanism, and the telescopic end of the telescopic component is fixedly connected to the connecting rod.

[0016] By setting the above structure, the telescopic component can extend and retract, allowing the intermediate conveying mechanism to slide along the slide rail. This allows for precise control of the distance between the intermediate conveying mechanism and the discharge end of the electronic belt scale, enabling the scraper on the intermediate conveying mechanism to scrape away as much of the tobacco material as possible from the discharge end of the electronic belt scale. It also meets the feeding needs of different tobacco materials.

[0017] The beneficial effects of this utility model are as follows:

[0018] This technical solution incorporates an intermediate conveying mechanism and a scraper. As the conveyor belt rotates, the scraper removes the smoke material extending from the electronic belt scale's outlet and temporarily stores it in a storage space. Because the material extending from the outlet is under its own weight, the pulling force between it and the smoke material on the outlet is weakened. The scraper can then easily remove it without disturbing the smoke material on the electronic belt scale. With the continuous operation of the electronic belt scale and intermediate conveying mechanism, smoke material continuously extends from the outlet and is scraped away by the scraper. When the scraper reaches the bottom of the intermediate conveying mechanism, the smoke material in the storage space automatically detaches under its own weight. The entire process is continuous, ensuring uniform material distribution on the conveyor belt and preventing any "white spots." The overall structure is simple, easy to use, and highly practical.

[0028] like Figure 1-5As shown in the figure, this utility model embodiment proposes an auxiliary feeding device for a tobacco quantitative feeder, including an intermediate conveying mechanism 3 disposed between an electronic belt scale 1 and a conveyor belt 2. The intermediate conveying mechanism 3 includes a conveyor belt 4, a support frame 5, and a drive assembly. In this embodiment, there are two support frames 5, and the conveyor belt 4 is installed between the two support frames 5. The drive assembly includes a motor 15, a drive roller, and a driven roller. The motor 15 is fixedly installed on the support frame 5 by bolts, and the drive roller is connected to the motor 15 for transmission. The structure of the support frame 5 and the drive assembly has been fully disclosed in the prior art, and will not be described in detail here. The drive assembly can drive the conveyor belt 4 to operate. A plurality of scraper plates 7 are evenly spaced along the circumference of the surface of the conveyor belt 4. In this embodiment, the intermediate conveying mechanism 3 is inclined from top to bottom away from the electronic belt scale 1. The top of the conveyor belt 4 is flush with the electronic belt scale 1, and the bottom of the conveyor belt is located above the conveyor belt 2. When the scraper plate 7 moves to the top of the conveyor belt 4, it can scrape away the smoke material extending from the discharge end of the electronic belt scale 1. The space between two adjacent scraper plates 7 forms a temporary storage space 14 for the scraped smoke material. When the scraper plate 7 moves to the bottom of the conveyor belt 4, the smoke material slides from the temporary storage space 14 onto the conveyor belt 2. When the scraper plate 7 moves to the side of the conveyor belt 4 away from the electronic belt scale 1, the scraper plate 7 is inclined from bottom to top away from the conveyor belt 4. Similarly, when the scraper plate 7 moves to the side of the conveyor belt 4 close to the electronic belt scale 1, the scraper plate 7 becomes inclined from top to bottom away from the conveyor belt 4.

[0029] The scraper 7 smoothly transitions with the conveyor belt 4 on the side closest to it. In this embodiment, the scraper 7 is numbered starting from any one scraper 7. Several scraper 7s are sequentially numbered 1*, 2*, 3*...n* along the rotation direction of the conveyor belt 4. When scraper 1* reaches the top of the conveyor belt 4, scraper 1* scrapes away the smoke material extending from the electronic belt scale 1. After this part of the smoke material is scraped away, the conveyor belt 4 continues to operate, and the scraped-away smoke material is temporarily stored in the temporary storage space 14 between scraper 1* and scraper 2*. Similarly, scraper 2* scraper 7... The smoke scraped off by the scraper 7 is temporarily stored in the temporary storage space 14 between the 2*scraper 7 and the 3*scraper 7. This process is repeated continuously. When the scraper 7 moves to the bottom of the intermediate conveyor mechanism 3, the smoke in the temporary storage space 14 naturally falls onto the conveyor belt 2. The smoke on the conveyor belt 2 is continuous and uniform. By smoothly transitioning the connection between the scraper 7 and the conveyor belt 4, the smoke in the temporary storage space 14 will not get stuck in any gaps that may exist between the scraper 7 and the conveyor belt 4. The smoke in the temporary storage space 14 falls smoothly and completely.

[0030] An arc-shaped rake 8 is provided along the length of the scraper 7 on the side away from the transmission belt. In this embodiment, the arc-shaped rake 8 can more easily scrape away the smoke material extending from the discharge end of the electronic belt scale 1. At the same time, the pulling force of the scraped smoke material on the smoke material still on the electronic belt scale 1 is insufficient to pull off the smoke material on the electronic belt scale 1, so that the amount of smoke material scraped away each time is constant, scraping is easy, and the continuity and uniformity of the smoke material on the conveyor belt 2 are further guaranteed.

[0031] Side plates 9 are fixed at both ends of the scraper 7 to prevent the smoke material in the temporary storage space 14 from falling from both ends of the scraper 7.

[0032] It also includes a slide rail 10 horizontally arranged on the ground. There are two slide rails 10 symmetrically arranged on both sides of the conveyor belt 4. The length direction of the slide rail 10 is parallel to the feeding direction of the electronic belt scale 1. Each support frame 5 has two support legs 11 on its outer side. The top of the support leg 11 is fixedly connected to the support frame 5. The bottom of the support leg 11 is slidably supported on the slide rail 10 through a sliding seat. A connecting rod 12 is fixedly provided between the support legs 11. A telescopic component 13 is provided on one side of the middle conveyor mechanism 3. The telescopic end of the telescopic component 13 is fixedly connected to the connecting rod 12. In this embodiment, the telescopic component 13 is a hydraulic cylinder. The telescopic component 13 is fixedly installed on the bracket (not shown in the figure) by bolts. By telescopically extending and retracting the telescopic component 13, the intermediate conveying mechanism 3 can slide along the slide rail 10, which can accurately control the distance between the intermediate conveying mechanism 3 and the discharge end of the electronic belt scale 1. This allows the scraper 7 on the intermediate conveying mechanism 3 to scrape away as much of the tobacco material extending from the discharge end of the electronic belt scale 1 as possible. At the same time, it can also meet the feeding requirements of different tobacco materials. For example, there will be slight differences in the distance between the intermediate conveying mechanism 3 and the discharge end of the electronic belt scale 1 for tobacco leaves and tobacco shreds.

[0033] like Figure 2 As shown, in this embodiment, the feeding direction of the electronic belt scale 1 is horizontal to the left, the rotation direction of the conveyor belt 4 is counterclockwise, and the feeding direction of the conveyor belt 2 is horizontal to the left.

[0034] Working principle:

[0035] As the conveyor belt 4 rotates, the scraper 7 scrapes away the smoke material extending from the discharge end of the electronic belt scale 1 and temporarily stores it in the temporary storage space 14. Due to the weight of the material extending from the discharge end of the electronic belt scale 1, the pulling force between the material and the smoke material at the discharge end of the electronic belt scale 1 is weakened. At this time, the arc-shaped rake 8 of the scraper 7 can easily scrape it away without pulling the smoke material on the electronic belt scale 1. As the electronic belt scale 1 and the intermediate conveyor mechanism 3 continue to operate, the smoke material continuously extends from the discharge end of the electronic belt scale 1 and is scraped away by the scraper 7. When the scraper 7 rotates to the bottom of the intermediate conveyor mechanism 3, the smoke material in the temporary storage space 14 automatically detaches under its own weight. The whole process is continuous, and the material on the conveyor belt 2 is continuous and uniform, avoiding the occurrence of "exposed white" material. The overall structure is simple, easy to use, and highly practical.
