Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco processing technology, and in particular to a loose structure and a cleaning machine. Background Technology
[0002] In modern tobacco processing, the spectral cleaning process is a crucial step in ensuring tobacco quality, responsible for removing impurities and loose tobacco clumps from the leaves. Currently, cleaning machines, utilizing advanced spectral recognition technology, can accurately distinguish between impurities and loose tobacco clumps in the leaves, effectively preventing impurities from entering the leaf storage cabinet and affecting subsequent production.
[0003] However, in existing technologies, once the tobacco blocks are identified, they fall directly into the recycling bin through the waste discharge pipe of the impurity removal machine and are treated as waste. While this achieves the separation of tobacco blocks from qualified tobacco sheets, it results in the waste of a large amount of usable tobacco block raw materials, directly increasing the raw material consumption costs of tobacco processing and also causing the unreasonable use of resources. Utility Model Content
[0004] The purpose of this utility model is to provide a loose structure and a cleaning machine to solve the problems of raw material waste and increased costs caused by treating block tobacco as waste, improve the recycling rate of block tobacco, reduce raw material consumption, and ensure the quality of tobacco sheets and the stability of tobacco processing.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A loose structure for loosening clumps of smoke within a feed pipe, the feed pipe including an inlet and an outlet, the loose structure comprising:
[0007] Multiple fixed loose parts are spaced apart along the axial direction of the discharge pipe on the first side wall of the discharge pipe;
[0008] The transmission assembly includes a chain, a drive sprocket, and a driven sprocket. The drive sprocket is located at one end of the discharge pipe near the feed inlet, and the driven sprocket is located at one end of the discharge pipe near the discharge outlet. The chain is wound around the drive sprocket and the driven sprocket.
[0009] Multiple movable loosening components are fixed to the chain at intervals along the length of the chain. The side of the chain closest to the first sidewall moves along the feed inlet toward the discharge outlet so that the movable loosening components and the fixed loosening components form an alternating fit.
[0010] As an alternative to the loose structure, a plurality of the fixed loose components extend obliquely from the first sidewall toward the inner cavity of the discharge pipe, and the extension direction of each fixed loose component forms an acute angle with the central axis of the discharge port.
[0011] As an alternative to the loose structure, along the axial direction of the feed tube, the extension length of the plurality of fixed loose components increases sequentially from the feed inlet to the discharge outlet.
[0012] As an alternative to the loose structure, both the fixed loose component and the movable loose component are conical in shape, and the end of the conical structure is provided with a hemispherical end.
[0013] As an alternative to the loose structure, the surfaces of the fixed loose parts and the movable loose parts are coated with a protective layer.
[0014] As an alternative to a loose structure, the protective layer is made of tungsten carbide.
[0015] As an alternative to the loose structure, multiple fixed loose components are arranged at equal intervals along the width direction of the first sidewall to form multiple rows of fixed loose components; multiple movable loose components are arranged at equal intervals along the width direction of the chain to form multiple rows of movable loose components, and each row of movable loose components can pass through the gap between the corresponding adjacent rows of fixed loose components.
[0016] As an alternative to a loose structure, the transmission assembly also includes a guide rail that extends axially along the feed tube to guide and support the movement of the chain.
[0017] As an alternative to the loose structure, the loose structure also includes a drive member fixed to the outer wall of the discharge tube, and the output shaft of the drive member passes through the discharge tube and is connected to the drive sprocket.
[0018] The impurity removal machine includes a discharge pipe, a recycling bin, and a loosening structure. The discharge pipe has an inlet and an outlet. The inlet is used to receive the smoke block, and the outlet is connected to the recycling bin. The loosening structure is installed on the discharge pipe and can loosen the smoke block. The recycling bin is used to receive the loosened smoke block.
[0019] Beneficial effects:
[0020] This invention provides a loosening structure that efficiently handles clumps of tobacco within the feed pipe, solving the problem of raw material waste and increased costs caused by the need for waste disposal due to clump formation. When the clumps of tobacco fall from the feed inlet onto a moving, movable loosening component, the component moves with the chain from the feed inlet to the discharge outlet, carrying the clumps of tobacco to a fixed loosening component. During this process, the movable and fixed loosening components work in an alternating pattern, tearing and peeling the clumps of tobacco. Mechanical force evenly disperses the clumps, restoring the previously unusable clumps to a processable state, significantly improving raw material recycling rates. The loosened tobacco can then re-enter the tobacco processing flow, avoiding raw material waste caused by clump formation and directly reducing raw material procurement costs and waste disposal expenses. Furthermore, the stable operation of the chain drive system ensures a continuously efficient loosening process, effectively preventing clogging of the feed pipe and guaranteeing the continuity and stability of tobacco production.
[0021] This invention provides a waste removal machine that, for separated tobacco clumps, utilizes the coordinated operation of a fixed loosening component and a movable loosening component within the feeding pipe. As the movable loosening component moves with the transmission assembly, it transports the tobacco clumps to the fixed loosening component. Through alternating cooperation, the two components mechanically break up the agglomerated tobacco clumps using a tearing and peeling method, restoring them to a processable state. This avoids waste disposal due to agglomeration, significantly reduces raw material loss, and effectively lowers raw material procurement and waste disposal costs. Attached Figure Description

[0035] This embodiment provides a waste removal machine, which includes a discharge pipe 100, a recycling bin (not shown), and a loosening structure. The discharge pipe 100 has an inlet 101 and an outlet 102. The inlet 101 is used to receive clumps of tobacco, and the outlet 102 is connected to the recycling bin. The loosening structure is installed on the discharge pipe 100 and can loosen the clumps of tobacco. The recycling bin is used to receive the loosened clumps of tobacco. When the clumps of tobacco enter the discharge pipe 100 through the inlet 101, the loosening structure can break up the clumps of tobacco, avoiding the waste of raw materials caused by agglomeration. The loosened clumps of tobacco fall directly into the recycling bin from the outlet 102, simplifying the recycling process, reducing manual transfer links, and reducing labor intensity. The recycling bin receives the loosened clumps of tobacco, which can be directly transported to the subsequent tobacco processing process, allowing the clumps of tobacco that were originally treated as waste to re-enter the production cycle, significantly reducing raw material procurement costs and waste disposal costs.
[0036] like Figures 1-4 As shown, the loosening structure is used to loosen the lumps of smoke inside the discharge pipe 100. The discharge pipe 100 includes an inlet 101 and an outlet 102. The loosening structure includes multiple fixed loosening components 1, a transmission assembly 3, and multiple movable loosening components 2. The multiple fixed loosening components 1 are spaced apart along the axial direction of the discharge pipe 100 on the first side wall 103 of the discharge pipe 100. The transmission assembly 3 includes a chain 31, a drive sprocket 32, and a driven sprocket 33. The drive sprocket 32 is located on the discharge pipe. At one end of the feed inlet 101, a driven sprocket 33 is located at one end of the discharge pipe 100 near the discharge outlet 102. A chain 31 is wound around the driving sprocket 32 and the driven sprocket 33. Multiple movable loosening parts 2 are fixed to the chain 31 at intervals along the length of the chain 31. The side of the chain 31 near the first side wall 103 moves along the direction from the feed inlet 101 to the discharge outlet 102, so that the movable loosening parts 2 and the fixed loosening parts 1 form an alternating fit.
[0037] By efficiently processing the lumps of tobacco within the feed pipe 100, the problem of raw material waste and increased costs caused by the need for waste disposal due to lumps of tobacco is solved. When the lumps of tobacco fall from the feed inlet 101 onto the moving movable loosening component 2, the movable loosening component 2 moves with the chain 31 from the feed inlet 101 to the discharge outlet 102, carrying the lumps of tobacco to the fixed loosening component 1. During this process, the movable loosening component 2 and the fixed loosening component 1 work in an alternating manner, tearing and peeling the lumps of tobacco. Mechanical force evenly disperses the lumped material, restoring the previously unusable lumps of tobacco to a processable state, significantly improving the raw material recycling rate. The loosened lumps of tobacco can then re-enter the tobacco processing process, avoiding the waste of raw materials due to lumps, directly reducing raw material procurement costs and waste disposal fees. Furthermore, the stable operation of the chain 31 transmission system ensures a continuously efficient loosening process, effectively preventing blockage of the feed pipe 100 and guaranteeing the continuity and stability of tobacco production.
[0038] In this embodiment, as Figure 1 and Figure 2As shown, the feeding pipe 100 is arranged vertically, with the inlet 101 located at the top and the outlet 102 located at the bottom, utilizing gravity to achieve natural falling conveying of the tobacco blocks. The feeding pipe 100 has a rectangular cross-section, with the transmission component 3 located near the second sidewall 104 opposite to the first sidewall 103. The cross-sectional area from the inlet 101 to the transmission component 3 is relatively small, while the corresponding position of the transmission component 3 has a larger cross-section due to the splicing design of the second sidewall 104. The tapering and expanding structure of the feeding pipe 100 guides the falling tobacco blocks, significantly reducing the possibility of the tobacco blocks slipping from the side without the fixed loosening component 1. This ensures that the tobacco blocks fall precisely between the two movable loosening components 2, guaranteeing that they are immediately received by the movable loosening components 2 and carried towards the fixed loosening component 1, triggering an alternating tearing and peeling action to achieve efficient loosening. In other embodiments, in addition to chain drive, synchronous belt drive can also be used.
[0039] like Figure 1 As shown, multiple fixed loosening components 1 extend obliquely from the first sidewall 103 toward the inner cavity of the discharge pipe 100, and the extension direction of each fixed loosening component 1 forms an acute angle with the central axis of the discharge port 102. First, the oblique layout increases the contact area and contact angle between the fixed loosening component 1 and the tobacco block. When the movable loosening component 2 carries the tobacco block through, the tearing and peeling force generated by the interlocking action of the two is more diverse, which can dismantle the agglomerated tobacco block from multiple angles and avoid incomplete loosening of the tobacco block. Second, the acute angle extension direction follows the downward trend of the tobacco block under the action of gravity, forming a downward guiding force on the tobacco block during the loosening process, which promotes the tobacco block to move more smoothly toward the discharge port 102 after loosening, reducing the risk of accumulation and jamming of the tobacco block in the discharge pipe 100. Furthermore, this inclined design effectively prevents smoke blocks from accumulating on the fixed loosening component 1. After the movable loosening component 2 completes its loosening action, the smoke blocks can quickly detach from the loosening area using their own gravity and the guidance of the inclined surface, ensuring the continuity of the loosening process, further improving the overall operating efficiency of the impurity remover, and reducing downtime maintenance costs caused by smoke block blockage. Specifically, the angle between the extension direction of the fixed loosening component 1 and the central axis of the discharge port 102 can be 70 degrees, 60 degrees, 50 degrees, 45 degrees, etc., and is not specifically limited here. In this embodiment, the inclination degree of multiple fixed loosening components 1 is the same, that is, the angle between the extension direction of each fixed loosening component 1 and the central axis of the discharge port 102 is equal.
[0040] like Figure 1As shown, along the axial direction of the discharge pipe 100, the extension length of multiple fixed loosening components 1 increases sequentially from the feed inlet 101 to the discharge outlet 102. Near the feed inlet 101, when the smoke block first enters the discharge pipe 100, it is relatively large and hard. At this point, the shorter fixed loosening components 1 initially contact the smoke block with less resistance, breaking up the surface clumps to prevent the smoke block from splashing or getting stuck due to excessive force. As the smoke block moves downwards, the length of the loosening components gradually increases, and the contact area and depth of action increase simultaneously. The initially loosened smoke block is more easily subjected to force, and the longer fixed loosening components 1 can penetrate deeper into the smoke block. Through more thorough interlocking with the movable loosening components 2, residual clumps are completely peeled off, ensuring a progressively improving loosening effect. This gradual layout also allows the smoke block to continuously adjust its posture during its descent, maintaining continuous contact with the loosening components and preventing accumulation due to uneven local loosening. In addition, the increasing extension length creates a downward guiding force gradient between the fixed loosening component 1 and the smoke block. Combined with gravity, this accelerates the movement of the smoke block toward the discharge port 102, significantly improving conveying efficiency, ensuring a smooth and stable loosening process, and minimizing raw material waste and equipment blockage risks.
[0041] like Figure 4 As shown, both the fixed loosening component 1 and the movable loosening component 2 have a conical structure, with a hemispherical end at the end of the conical structure. The design of both fixed and movable loosening components 1 and 2 using a conical structure with a hemispherical end significantly reduces damage to the tobacco leaves. When the conical structure comes into contact with the tobacco block, its gradually narrowing shape evenly distributes the loosening force, reducing stress concentration; while the hemispherical end, with its smooth curved surface instead of a sharp tip, greatly weakens the cutting and tearing effect on the tobacco leaves. During the alternating engagement of the movable loosening component 2 carrying the tobacco block and the fixed loosening component 1, while ensuring the loosening effect, damage to the physical structure of the tobacco leaves is minimized, reducing the tobacco leaf breakage rate. This improves the quality and usability of recycled tobacco leaves, reduces waste generation and cost increases due to tobacco leaf breakage, and ensures the stability of raw material quality in tobacco processing.
[0042] In this embodiment, a protective layer (not shown) is applied to the surfaces of multiple fixed loose parts 1 and multiple movable loose parts 2. The protective layer effectively isolates the fixed loose parts 1 and movable loose parts 2 from direct friction with the smoke block, preventing problems such as surface peeling and deformation of the metal material due to long-term wear, extending the service life of the loose parts, and reducing equipment maintenance and replacement costs. At the same time, the smooth surface characteristics of the protective layer greatly reduce the friction between the loose parts and the smoke block, making the movement of the smoke block by the movable loose parts 2 smoother, reducing the load on the transmission components 3 caused by excessive frictional resistance, and ensuring stable operation of the equipment.
[0043] Optionally, the protective layer is made of tungsten carbide. Using tungsten carbide as the surface protective layer for loose parts, due to its high hardness and wear resistance, can significantly reduce wear on loose parts caused by tobacco friction, extending the service life of the equipment. Its smooth, low-resistance characteristics reduce friction between tobacco leaves and loose parts, lowering the tobacco breakage rate. Simultaneously, tungsten carbide is chemically stable and will not react with tobacco leaves, avoiding contamination that affects quality. It combines durability and safety, effectively reducing maintenance costs and raw material losses while improving production efficiency. Optionally, the protective layer can also be made of composite materials such as ceramic-metal composite coatings, graphene-modified coatings, and food-grade silicone.
[0044] like Figure 2 As shown, multiple fixed loose parts 1 are arranged at equal intervals along the width direction of the first sidewall 103 to form multiple rows of fixed loose parts; multiple movable loose parts 2 are arranged at equal intervals along the width direction of the chain 31 to form multiple rows of movable loose parts, and each row of movable loose parts can pass through the gap between the corresponding adjacent rows of fixed loose parts. The arrangement of multiple fixed loose parts 1 at equal intervals along the width direction of the first sidewall 103 to form multiple rows of fixed loose parts ensures that the fixed loose parts 1 form a uniformly distributed interception structure in the width dimension of the first sidewall 103. When the smoke block falls from the feed inlet 101 of the discharge pipe 100, regardless of the lateral position of the smoke block in the corresponding plane of the first sidewall 103, it will contact the fixed loose parts 1 in different rows, thereby avoiding local contact blind spots caused by uneven spacing. Meanwhile, multiple movable loosening components 2 are arranged at equal intervals along the width direction of the chain 31, forming multiple rows of movable loosening components. Driven by the transmission component 3, the movable loosening component rows can pass through the gaps between corresponding adjacent fixed loosening component rows with precise movement trajectories, thereby forming a loose structure similar to "interlaced comb teeth" inside the feed tube 100. When the movable loosening component rows move with the chain 31, the spatial interlacing of the movable and fixed loosening component rows will generate multi-dimensional mechanical forces on the tobacco block. Not only will it apply longitudinal loosening force along the direction of tobacco block falling, but it will also generate lateral shearing force through the transverse interlacing gap movement, so that the agglomerated tobacco block can be gradually peeled off and broken up in three-dimensional space.
[0045] like Figure 1As shown, the transmission assembly 3 also includes a guide rail 34, which extends axially along the feed tube 100 to guide and support the movement of the chain 31. The guide rail 34 provides precise guidance and rigid support for the movement of the chain 31 and the movable loose parts, preventing the chain 31 from shifting due to gravity or uneven force, ensuring that the movable loose parts 2 can accurately pass through the gaps in the fixed loose parts, maintaining the optimal loosening distance. Simultaneously, the guide rail 34 can evenly distribute the load on the chain 31, reducing sprocket wear, and its smooth surface can also reduce the running resistance of the chain 31 and lower energy consumption. Furthermore, the guide rail 34 can effectively suppress chain 31 vibration, ensure stable transmission of loosening force, improve the uniformity of tobacco block loosening, reduce tobacco loss, and its modular design facilitates maintenance, significantly shortening maintenance time and improving equipment operating efficiency and production continuity.
[0046] like Figure 3 As shown, the loose structure also includes a drive component 4, which is fixed to the outer wall of the discharge tube 100. The output shaft of the drive component 4 passes through the discharge tube 100 and is connected to the drive sprocket 32. A bearing seat is provided on the outer wall of the discharge tube 100, providing a stable and low-friction support foundation for the drive shaft of the drive component 4. The drive shaft at the output end of the drive component 4 passes through the side wall of the discharge tube 100 and is connected to the drive sprocket 32. Under the action of the bearing seat, the drive shaft can achieve high-precision rotation, effectively reducing vibration and noise caused by eccentricity or wobbling. The presence of the bearing seat distributes the radial and axial forces on the drive shaft when transmitting torque, preventing the drive component 4 from directly bearing additional stress and extending its service life.
[0047] Specifically, the drive unit 4 uses a stepper motor or servo motor, supporting frequency conversion speed regulation, and can adjust the speed in real time according to the hardness of the tobacco blocks: when dealing with hard, agglomerated tobacco blocks, the drive unit 4 can output high torque and low speed to peel off the tobacco blocks layer by layer with strong power; when dealing with softer agglomerated tobacco blocks, it switches to a high speed and low torque mode to quickly complete the loosening operation. By precisely matching the motor parameters with the characteristics of the tobacco blocks, it avoids damage to the tobacco leaves due to excessive speed and prevents low loosening efficiency due to insufficient torque, achieving the optimal balance between loosening effect and raw material loss.
[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
