Description

Technical Field

[0001] This utility model relates to the field of tobacco shredder technology, and in particular to a tobacco shredder with a chain cleaning mechanism. Background Technology

[0002] In the tobacco processing industry, tobacco shredders are indispensable and important pieces of machinery. Their main function is to cut tobacco leaves or stems into fine shreds. Shredded tobacco is easier to roll, burn, and smoke, playing a key role in ensuring the taste and quality of tobacco products and meeting the industry's demand for finely shredded tobacco products.

[0003] Existing tobacco shredders typically use upper and lower chain conveyors to transport tobacco raw materials. However, during long-term operation, tar can easily adhere to the tiny gaps in the copper chain. This accumulated tar not only affects the cleanliness of the chain but also gradually reduces mechanical efficiency and even poses a potential threat to the quality of the final tobacco product. To ensure chain cleanliness, improve chain efficiency, and guarantee product quality, it is essential to clean the tar from the gaps in the copper chain promptly.

[0004] Currently, traditional cleaning methods rely on manual operation, using brushes for meticulous cleaning. However, this method has significant drawbacks: manual operation is time-consuming, labor-intensive, inefficient, and it is difficult to guarantee thoroughness and uniformity of cleaning. Especially in large-scale, continuous production environments, manual cleaning methods can no longer meet the requirements of efficient and precise production. Utility Model Content

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] like Figures 1 to 3As shown, this embodiment provides a tobacco shredder with a chain cleaning mechanism, including a frame 1. The frame 1 is provided with at least one chain module. The chain module includes a chain working mechanism and a chain cleaning mechanism. The chain working mechanism includes at least two drive rollers and a conveyor belt sleeved on all the drive rollers. The chain cleaning mechanism includes a plurality of brushes 16. The brushes 16 are used to clean impurities on the conveyor belt. Some of the brushes 16 are in contact with the outer surface of the conveyor belt, and the remaining brushes 16 are in contact with the inner surface of the conveyor belt. The brushes 16 can move relative to the chain working mechanism along the width direction of the conveyor belt.

[0029] This tobacco shredder with a chain-fed cleaning mechanism is equipped with a chain-fed module, including a chain-fed working mechanism and a chain-fed cleaning mechanism. The chain-fed cleaning mechanism features brushes 16 that contact the inner and outer surfaces of the conveyor belt, enabling comprehensive cleaning of both surfaces. This effectively removes impurities adhering to the conveyor belt, ensuring its cleanliness and preventing impurities from adversely affecting the operation of the tobacco shredder and the quality of materials. This reduces the risk of contamination and improves the stability and reliability of material transport, providing a good foundation for subsequent material processing. Simultaneously, the brushes 16 can move relative to the chain-fed working mechanism along the width of the conveyor belt, providing more comprehensive coverage of the belt surface. This expands the cleaning range, ensuring that impurities at different locations across the entire width of the conveyor belt are cleaned, thus significantly improving cleaning efficiency, greatly shortening the cleaning cycle, enhancing the operating efficiency of the tobacco shredder, saving labor costs, optimizing the production process, and ensuring the flexibility and effectiveness of cleaning.

[0030] In this embodiment, the material is tobacco leaves, and the impurities include oil stains, tobacco oil, and tobacco leaf debris.

[0031] In this embodiment, the frame 1 is provided with a fixed plate 12, and the chain cleaning mechanism also includes a connecting rod 15 and a push plate 13. The push plate 13 and all the brushes 16 are located on both sides of the fixed plate 12. The number of connecting rods 15 is the same as the number of brushes 16. Each brush 16 is connected to the push plate 13 through a connecting rod 15, and the connecting rod 15 passes through the fixed plate 12.

[0032] The brush 16 is connected to the push plate 13 by means of the fixed plate 12, the connecting rod 15 and the push plate 13. The connecting rod 15 passes through the fixed plate 12, so that the brush 16 has stable support and guidance during movement. This ensures the stability of the brush 16 when the connecting rod 15 drives the brush 16 to move, and guarantees the stability and accuracy of the movement of the brush 16. It also prevents the brush 16 from shaking or deviating, thereby cleaning the conveyor belt more accurately, ensuring the reliability of the cleaning work and improving the cleaning effect.

[0033] Furthermore, the chain cleaning mechanism also includes a pushing unit 14, the output end of which is connected to the pushing plate 13. The pushing unit 14 is used to drive the pushing plate 13 to reciprocate along the width direction of the conveyor belt. Specifically, the pushing unit 14 is fixed to the frame 1 and is a cylinder.

[0034] The chain cleaning mechanism is equipped with a push unit 14 to drive the push plate 13 to move back and forth along the width of the conveyor belt, thereby driving the brush 16 to perform reciprocating cleaning. This automates the cleaning process of the brush 16, eliminating the need for manual operation, greatly improving cleaning efficiency, and reducing manpower and cleaning time. Simultaneously, the reciprocating movement allows for a more comprehensive and thorough cleaning of the conveyor belt, ensuring the regularity and consistency of the cleaning process and improving its uniformity.

[0035] In this embodiment, the connecting rod 15 extends along the width direction of the conveyor belt; the fixing plate 12 has a through hole extending along the width direction of the conveyor belt, the number of through holes is the same as the number of connecting rods 15, and each connecting rod 15 passes through one through hole.

[0036] The connecting rod 15 extends along the width of the conveyor belt, and the clearance hole on the fixing plate 12 corresponds to the connecting rod 15. The clearance hole plays a certain guiding role for the connecting rod 15, providing a smooth channel for the movement of the connecting rod 15, so that the connecting rod 15 will not be obstructed during the movement, reducing the resistance and interference of the brush 16 during the movement, ensuring that the connecting rod 15 can smoothly drive the brush 16 to move along the width of the conveyor belt for cleaning, and improving the reliability and stability of the chain cleaning mechanism.

[0037] For example, the plane on which the fixing plate 12 is located is perpendicular to the width direction of the conveyor belt.

[0038] This layout ensures that the connecting rod 15 and the brush 16 maintain an accurate relative position with respect to the width direction of the conveyor belt during movement. This makes the force on the connecting rod 15 more even when it passes through the fixed plate 12, ensuring the stability and straightness of the brush 16 during movement. It also helps the brush 16 maintain good contact with the surface of the conveyor belt during movement, ensuring the uniformity and consistency of the brush 16 in cleaning the surface of the conveyor belt, and improving the efficiency and quality of cleaning.

[0039] In this embodiment, there are two chain-laying modules, and the chain-laying working mechanisms on the two chain-laying modules are a lower copper chain assembly 4 and an upper copper chain assembly 5, respectively. The upper copper chain assembly 5 is located above the lower copper chain assembly 4, and a first collection box 10 for collecting impurities is provided below the lower copper chain assembly 4. Specifically, the first collection box 10 is movably mounted on the frame 1.

[0040] Two chain conveyor modules are provided: a lower copper chain assembly 4 and an upper copper chain assembly 5, with a first collection box 10 located below the lower copper chain assembly 4. The two chain conveyor assemblies allow for more stable material transport and improve conveying efficiency. The first collection box 10, positioned below the lower copper chain assembly 4, promptly collects impurities swept from the chain conveyor module, preventing them from scattering inside the machine or in the surrounding environment, maintaining a clean working environment, and facilitating centralized processing of impurities.

[0041] The chain cleaning mechanism can effectively clean the surface of the copper busbars and the gaps between adjacent copper busbars, thereby sweeping out and collecting the oil stains and soot adhering to the gaps, effectively maintaining the cleanliness of the copper busbars, laying a solid foundation for the subsequent processing of materials, and avoiding the potential impact on the quality of the final product due to improper cleaning.

[0042] Furthermore, the frame 1 is also equipped with two second collection boxes 11 for collecting impurities, which are located on both sides of the upper copper busbar chain assembly 5 in the width direction. Specifically, the second collection boxes 11 are movably mounted on the frame 1.

[0043] Two second collection boxes 11 are set on the frame 1, located on both sides of the upper copper busbar chain assembly 5 in the width direction. They can collect impurities swept down from the upper copper busbar chain assembly 5, prevent impurities from scattering, ensure the integrity of impurity collection, further improve the impurity collection system, and ensure that all swept impurities can be effectively collected.

[0044] In this embodiment, the frame 1 is also provided with a processing module for processing materials. There is a feeding space between the lower copper busbar assembly 4 and the upper copper busbar assembly 5. The lower copper busbar assembly 4 and the upper copper busbar assembly 5 are used to transfer the materials in the feeding space to the processing module.

[0045] The lower copper busbar chain assembly 4 and the upper copper busbar chain assembly 5 form a feeding space, which can stably transport materials to the processing module, realize the seamless connection between material conveying and processing, improve the continuity and automation of the production process, reduce the time loss of materials in the conveying and processing process, ensure the continuity and stability of material conveying, provide a reliable material supply for subsequent material processing, and improve the production efficiency of the entire tobacco shredder.

[0046] For example, the drive roller includes a sprocket, the conveyor belt includes two chains and several copper busbars, the copper busbars extend along the width direction of the conveyor belt, and the two ends of the copper busbars are respectively hinged to the two chains, and the chains are driven by the sprocket.

[0047] The use of a combination of sprockets and chain drives, along with a structure where copper busbars are hinged to the chain, makes the conveyor belt's transmission more stable and reliable. This ensures accurate power transmission and guarantees the conveyor belt's operational precision, thereby accurately conveying materials. Simultaneously, the copper busbar design increases the contact area between the conveyor belt and the material, improving the stability of material conveying. This design is suitable for the material conveying requirements of tobacco shredders, increasing the conveyor belt's load-bearing capacity and durability.

[0048] Specifically, the lower copper busbar chain assembly 4 includes a lower sprocket 41, a lower chain 42, and a first copper busbar 43. The lower sprocket 41 is rotatably connected to the frame 1, the lower chain 42 is meshed with the lower sprocket 41, and the first copper busbar 43 is fixedly connected to the lower chain 42. The lower sprocket 41 is used to drive the lower chain 42 to rotate, thereby driving the first copper busbar 43 to move. The upper copper busbar chain assembly 5 includes an upper sprocket 51, an upper chain 52, and a second copper busbar 53. The upper sprocket 51 is rotatably connected to the frame 1, the upper chain 52 is meshed with the upper sprocket 51, and the second copper busbar 53 is fixedly connected to the upper chain 52. The upper sprocket 51 is used to drive the upper chain 52 to rotate, thereby driving the second copper busbar 53 to move.

[0049] In this embodiment, the frame 1 is also provided with a drive structure, which is used to drive the drive roller to rotate around its own axis.

[0050] The drive structure provides power for the rotation of the drive roller, ensuring the normal operation of the chain conveying mechanism. This allows for continuous and stable material conveying and chain cleaning, ensuring the normal operation of the entire tobacco shredder. Furthermore, the speed of the drive roller can be flexibly adjusted according to production needs, thereby controlling the material conveying speed.

[0051] In this embodiment, a hopper 2 is also fixedly connected to the frame 1. A pusher plate 3 is provided at the bottom of the hopper 2. The hopper 2 is used to feed tobacco leaves, and the pusher plate 3 is used to push the tobacco leaves so that the material in the hopper 2 is guided into the feeding space.

[0052] For example, the processing module includes a grinding wheel 6, a tool gate 7 and a cutting roller 8. The tool gate 7 is fixedly connected to the frame 1, and the cutting roller 8 is rotatably connected to one side of the tool gate 7. The grinding wheel 6 is disposed on the cutting roller 8, and the bottom end of the cutting roller 8 is provided with a blade outlet 9.

[0053] The cutting gate 7 applies pressure to the tobacco leaves, forming a dense tobacco cake for easier subsequent cutting. During rotation, the cutting blades on the cutting roller 8 cut the tobacco leaves passing through the cutting gate 7 into shreds of a certain width, which are then discharged from the shred outlet 9. The grinding wheel 6 continuously sharpens the cutting blades on the cutting roller 8 to ensure sharpness, thereby guaranteeing the quality and efficiency of tobacco shredding.
