Description

Technical Field

[0001] This utility model belongs to the technical field of tobacco processing equipment, specifically relating to a tobacco feeding device for the tobacco packing process in cigarette production. Background Technology

[0002] In the tobacco processing industry, tobacco packing is a crucial step in achieving quantitative storage and transportation of tobacco. The uniformity of the packing directly affects the packing density, subsequent processing quality, and storage efficiency. Existing tobacco packing systems commonly employ a structure where a longitudinal tobacco conveyor and a transverse packing conveyor are arranged perpendicularly, such as CN113306752A, "Tobacco Packing System and Method," which uses multi-stage conveying to deliver the tobacco to the packing conveyor. However, this type of structure has the following technical drawbacks: 1. Large space occupation and limited layout: Longitudinal conveyors require a large installation space in the vertical direction, which is especially difficult to meet the needs of multiple workstations operating in parallel on production lines with limited equipment deployment area. For example, although the CN215707271U tobacco packing system reduces some space occupation by optimizing the position of the conveyor, it still relies on a fixed workstation layout, which lacks flexibility.

[0003] 2. Poor uniformity of material distribution affects packing quality: Traditional technology relies on a single feeding port for direct material feeding, which easily leads to the accumulation of tobacco shreds in the middle of the material conveyor, resulting in uneven packing density distribution. This requires additional manual intervention for adjustment, increasing operating costs. Although some solutions (such as CN108910131A, a horizontal tobacco packing system and packing method) improve the material distribution effect through a reciprocating material spreading mechanism, their structure is complex and maintenance is difficult.

[0004] 3. Dust generation and spillage are prominent issues: During free fall, tobacco generates a large amount of dust due to kinetic energy impact, which not only pollutes the working environment but may also pose safety hazards. Current technologies lack targeted dust removal designs and rely solely on localized dust collection devices, making it difficult to achieve comprehensive dust control throughout the entire process.

[0005] Furthermore, while systems like CN215707271U (tobacco packing system) mention a "many-to-one" sliding device to improve flexibility, their core focus remains on adjusting the conveying path, without addressing the synergistic optimization of fabric uniformity and space utilization. Therefore, there is an urgent need for a compact, uniformly fabricated, and dust-proof tobacco unloading device and method to solve the technical challenges of multi-station layout within confined spaces and improving packing efficiency and quality. Utility Model Content

[0006] To address the aforementioned issues, this utility model provides a tobacco feeding device for the tobacco packing process in cigarette production.

The top end of the driving rod on the side of the set of driving rods closest to the power source is hinged to the output end of the power source.

[0011] Furthermore, the bottom of the hopper forms a channel for the passage of tobacco shreds through parallel spaced material-pulling plates, and this channel is driven by a power source and a transmission component to drive the drive shaft of the swing arm assembly, causing it to reciprocate and swing relative to the enclosed transverse tobacco shred conveyor.

[0012] Furthermore, a protective cover is provided on the outer side of the tobacco feeding device to cooperate with the cloth driving assembly and the transmission assembly.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 As shown, this embodiment provides a tobacco feeding device for the tobacco packing process in cigarette production, which is particularly suitable for automated production lines with high requirements for fabric uniformity and limited installation space. This device aims to achieve efficient, uniform, and low-dust feeding of tobacco from the upstream electronic belt scale 6 to the fabric conveyor, effectively solving the problems of large space occupation, uneven fabric distribution, and severe dust generation in traditional technologies.

[0024] The tobacco packing system comprises a tobacco box conveyor line 1 consisting of several conveying mechanisms, with double packing stations 2 on the conveyor line 1. An equipment frame 3 is installed at each double packing station 2, and a closed transverse tobacco conveyor 4 located between the two packing stations is mounted on the equipment frame 3. This structure is a mature existing equipment; for detailed structure, please refer to the tobacco packing system and packing method disclosed in patent application number CN202411927782.3.

[0025] The tobacco feeding device 5 provided in this embodiment is installed on the equipment frame 3. Its upper end is connected to the discharge port on one side of the electronic belt scale 6, and its lower end is connected to the enclosed transverse tobacco conveyor 4. The feed port on the other side of the electronic belt scale 6 is connected to the upstream tobacco conveyor line 7. The electronic belt scale 6 is a commercially available finished product, such as the KSD-ZP2000 electronic belt scale from Kunming Shipbuilding Intelligent Technology Co., Ltd. The tobacco conveyor line 7 is composed of a commercially available KSF-F800 scraper feeder from Kunming Shipbuilding Intelligent Technology Co., Ltd. and a JTS-B800 light belt conveyor from Jiujiang No. 7 Precision Electromechanical Technology Co., Ltd. The tobacco is conveyed by the tobacco conveyor line 7 to the electronic belt scale 6 for weighing. After the weight requirement is met, the electronic belt scale 6 conveys the tobacco to the enclosed transverse tobacco conveyor 4 through the tobacco feeding device 5. Then, the enclosed transverse tobacco conveyor 4 conveys the tobacco to the corresponding packing station, realizing continuous tobacco feeding.

[0026] The specific structure of the tobacco feeding device 5 provided in this embodiment is as follows: like Figure 2 and Figure 3As shown, the tobacco feeding device 5 is a rectangular box with an internal cavity structure, and a feeding hopper 10 is fixedly installed inside the rectangular box. The discharge port on one side of the electronic belt scale 6 passes through the top surface of the tobacco feeding device 5 and connects to the feeding hopper 10. The bottom of the feeding device body is fixedly connected to the enclosed horizontal tobacco conveyor 4. The tobacco feeding device 5 forms a tobacco feeding channel, which, together with the hopper, buffers and guides the tobacco, preventing blockage.

[0027] like Figure 2 and Figure 3 As shown, the tobacco feeding device 5 in this embodiment is also equipped with a rotating feeding roller mechanism 8 and a swing-type feeding mechanism 9. The feeding roller mechanism 8 dynamically moves the tobacco, and the feeding mechanism 9 swings back and forth to evenly distribute the tobacco to the left and right sides of the enclosed transverse tobacco conveyor 4.

[0028] Feeding roller mechanism 8: such as Figure 1 As shown, the feeding roller mechanism 8 includes a feeding drive motor 81 and a feeding roller 82. The feeding drive motor 81 is mounted outside the tobacco feeding device 5 and is positioned opposite to the feeding mechanism 9. The output shaft of the feeding drive motor 81 is fixedly connected to one end of the feeding roller 82, and is used to drive the feeding roller 82 to rotate. Figure 1 , Figure 2 and Figure 3 As shown, the feeding roller 82 is rotatably mounted on the housing of the feeding device via the first bearing 84, and horizontally penetrates the feeding hopper 10 inside the device. Multiple feeding rods 83 are evenly arranged circumferentially on the roller section of the feeding roller 82 located within the feeding hopper 10, used to dynamically agitate and disperse the tobacco shreds during the falling process. When the feeding drive motor 81 starts, it drives the feeding roller 82 to rotate continuously, and the feeding rods 83 agitate the tobacco shreds accordingly, effectively preventing problems such as accumulation and blockage of the tobacco shreds during the feeding process. The feeding roller mechanism 8 not only enhances the continuity of the feeding process but also further improves the uniformity of the tobacco shred distribution.

[0029] Fabric Mechanism 9: such as Figure 2 and Figure 3 As shown, the fabric feeding mechanism 9 includes three parts: a fabric driving assembly, a swing arm assembly, and a transmission assembly. The three parts work together to achieve a uniform lateral distribution of tobacco shreds on the enclosed transverse tobacco conveyor 4.

[0030] like Figure 1 As shown, the fabric drive assembly is installed outside the tobacco feeding device 5 and is positioned opposite to the feeding roller mechanism 8. Figure 2 and Figure 3As shown, the fabric driving assembly mainly includes a power source 91, a connecting seat 92, a connecting rod, a mounting seat 93, and a mounting plate 94. The power source 91 is rotatably mounted on the connecting seat 92; the connecting seat 92 is fixedly connected to the mounting seat 93 via the connecting rod; and the mounting seat 93 is securely fixed to the outer wall of the tobacco feeding device 5 via the mounting plate 94. In this embodiment, the power source 91 is preferably an electric cylinder, which features fast response and high control precision, and can flexibly adjust its stroke according to process requirements, thereby achieving precise control of the fabric angle.

[0031] like Figure 2 and Figure 3 As shown, there are two sets of swing arm assemblies arranged in parallel at intervals. Each set of swing arm assemblies includes a drive shaft 96 rotatably mounted on the material feeding device housing via a second bearing 95. The drive shaft 96 is located on the left and right sides below the material feeding hopper 10. A material guiding plate 97 is fixedly installed on the shaft section of the drive shaft 96 that extends into the material feeding device. The material guiding plates 97 of the two sets of swing arm assemblies always remain parallel, together forming a reciprocating swinging material feeding channel to guide the tobacco shreds to fall into different areas of the enclosed transverse tobacco conveyor 4.

[0032] like Figure 2 and Figure 3 As shown, the transmission assembly is located outside the tobacco feeding device 5 and adopts an n-shaped multi-link structure, mainly including a set of parallel drive rods 98, connecting rods 99, and other components. The lower ends of the drive rods 98 are fixedly connected to two drive shafts 96 to achieve synchronous drive; the upper ends of the drive rods 98 are hinged to both ends of the connecting rods 99 to form a linkage structure. On the side near the power source 91, the top end of one of the drive rods 98 is hinged to the output end of the power source 91. The extension and retraction of the power source 91 drives the entire transmission assembly to move, thereby driving the swing arm assembly to reciprocate.

[0033] The working principle and function of the fabric mechanism 9 are as follows: When the power source 91 is activated, it drives the drive shaft 96 to rotate via the transmission assembly, thereby causing the feeding plate 97 to cycle between position 0, position 1, and position 2; position 0, for example... Figure 4 As shown, a set of feeding plates 97 are vertically parallel and located in the middle of the enclosed transverse tobacco conveyor 4; position 1 is as follows. Figure 5 As shown, a set of feeding plates 97 are inclined and parallel, located on the right side of the enclosed transverse tobacco conveyor 4; position 2 is as follows Figure 6As shown, a set of material guide plates 97 are inclined and parallel, located on the left side of the enclosed transverse tobacco conveyor 4. The tobacco shreds fall through the channel formed by the set of material guide plates 97 at the bottom of the hopper 10, and are alternately guided onto the enclosed transverse tobacco conveyor 4 by the swinging action of the material guide plates 97, so as to achieve uniform transverse distribution of tobacco shreds on the enclosed transverse tobacco conveyor 4.

[0034] The reciprocating swing of the swing arm assembly guides the tobacco shreds alternately from the middle of the conveyor to the left and right sides, significantly improving the uniformity of the fabric distribution. The power source 91, in conjunction with the transmission assembly, enables precise control of the fabric distribution angle, adapting to different working conditions. The fabric distribution mechanism 9 has a compact structure and stable operation, effectively reducing manual intervention and improving packing efficiency and quality consistency.

[0035] As a preferred technical solution in this embodiment, such as Figure 1 As shown, a protective cover 11 is provided on one side of the tobacco feeding device 5 to cover the fabric drive assembly and transmission assembly. This protective cover 11 effectively prevents tobacco fragments or dust from entering the mechanical moving parts, ensuring safe operation of the equipment and extending its service life. Furthermore, as... Figure 2 As shown, the outer wall of the tobacco feeding device 5 is also equipped with auxiliary structures such as a reinforcing plate 51, an observation window 52, ​​and lifting lugs, which are used to improve the overall structural strength and maintenance convenience of the device. The reinforcing plate 51 is fixedly installed inside the feeding device body to enhance structural rigidity, prevent deformation caused by equipment vibration, and improve operational stability. The observation window 52 is located on the outer wall of the feeding device, allowing operators to monitor the flow of tobacco inside the hopper in real time, providing a direct reference for adjusting the parameters of the feeding mechanism 9 and the feeding roller mechanism 8. The lifting lugs are located on the top or side wall of the device (not shown in the figure); the lifting lugs facilitate the quick disassembly and installation of the tobacco feeding device 5, improving equipment maintenance and replacement efficiency. Furthermore, as... Figure 1 As shown, an industrial dust removal device 12 is installed on the top of the tobacco feeding device 5. In this embodiment, the preferred type is the YC-DC500 industrial vacuum cleaner from Suzhou Yuanchuang Environmental Protection Technology Co., Ltd. The industrial dust removal device 12 is connected to the inside of the tobacco feeding device 5 through a suction pipe. It can collect the dust generated during the falling of the tobacco in a timely manner, prevent dust from overflowing and polluting the working environment, and reduce the dust concentration to ensure the health of operators and production safety.

[0036] In summary, this tobacco feeding device, through structural optimization and functional integration, effectively solves the problems of large space occupation, uneven material distribution, and severe dust generation in traditional tobacco packing systems. The device adopts an integrated design of a closed transverse tobacco conveyor and feeding unit, eliminating the longitudinal conveying path, significantly saving installation space, and adapting to multi-station layouts. Internally, a feeding roller mechanism and a swing-type feeding mechanism work together. The feeding roller dynamically disperses the tobacco through a rotating feeding rod, while the feeding mechanism drives the feeding plate to swing back and forth via an electric cylinder, achieving uniform transverse distribution of tobacco on the conveyor and improving packing density consistency. An integrated industrial dust collection device at the top collects dust generated during the feeding process in real time, improving the working environment. Furthermore, the device is externally equipped with a protective cover, observation window, reinforcing plate, and lifting lugs to enhance operational stability and ease of maintenance. With its compact structure, uniform material distribution, and excellent dust prevention, it is suitable for automated tobacco production lines with high requirements for material distribution accuracy and spatial layout.
