Description

Technical Field

[0001] This utility model relates to the technical field of tobacco equipment cleaning devices, and in particular to a cleaning device for the rake nails of a feeder lifting belt. Background Technology

[0002] In tobacco processing, the feeder, as a key piece of equipment for material conveying, directly impacts the material utilization rate and production efficiency of subsequent processing stages by improving the cleaning effect of the rake. With the tobacco industry's increasing demands for automated production and refined management, reducing material loss and lowering labor maintenance costs have become important directions for equipment optimization.

[0003] Currently, traditional lifting feeders primarily use brush rollers or fixed sealing strips to clean the rake nails. Brush rollers clean by contacting and rubbing against the rake nail surface, but the bristles easily wear and deform after prolonged use, resulting in incomplete cleaning of residual tobacco leaves at the base of the rake nails and in crevices. Fixed sealing strips rely on elastic compression to adhere to the rake nail surface; when the rake nails have slight deformation or positional deviations, gaps easily appear in the sealing strip, also failing to completely remove attached tobacco leaves. These existing technologies generally suffer from inconsistent cleaning effectiveness, causing a large amount of tobacco leaves to be carried out by the rake nails and fall into the receiving box. If not cleaned promptly, the tobacco leaves accumulate in the receiving box, rapidly losing moisture and significantly increasing the breakage rate, resulting in severe material loss.

[0004] To solve the above problems, a large number of operators need to be arranged on site to manually clean the rake nails and receiving box regularly. This not only increases labor costs, but may also affect the continuity of production due to untimely cleaning. At the same time, there are potential safety hazards in equipment operation during manual operation. Utility Model Content

[0005] The purpose of this utility model is to provide a feeder lifting belt rake nail cleaning device, which can effectively clean tobacco leaves adhering to the rake nails, reduce material loss, reduce labor costs, and improve production continuity.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A device for cleaning rake nails on a feeder elevator belt is provided, comprising:

[0008] A bracket is used to be installed below the drive roller of the feeder;

[0009] The drive wheel is coaxially and fixedly connected to the drive roller of the feeder.

[0010] The cleaning roller is rotatably connected to the support, and the axial direction of the cleaning roller is parallel to and spaced apart from the axial direction of the drive roller. The outer peripheral wall of the cleaning roller is provided with a cleaning assembly, which includes multiple ribs. The multiple ribs are distributed at intervals along the axial direction of the cleaning roller. The gap between adjacent ribs corresponds one-to-one with the rake nails on the feeder conveyor belt. The gap is used for the rake nails to pass through so that the ribs can clean the material on the rake nails.

[0011] The driven wheel and the transition wheel are coaxially arranged and fixedly connected to the cleaning roller. The transition wheel is rotatably connected to the bracket and located below the driven wheel. The axial direction of the transition wheel is parallel to the axial direction of the driven wheel and is spaced apart. The driving wheel is connected to the transition wheel and the driven wheel in sequence through a transmission component.

[0012] As one possible implementation of the above-mentioned feeder lifting belt rake nail cleaning device, multiple cleaning components are provided, and the multiple cleaning components are distributed along the circumference of the cleaning roller.

[0013] As one possible implementation of the above-mentioned feeder lifting belt rake nail cleaning device, each stiffener is provided with a cleaning component on the side near the adjacent stiffener, and the cleaning component is used to clean the material on the rake nail passing through the corresponding gap.

[0014] As one possible implementation of the above-mentioned feeder lifting belt rake nail cleaning device, the cleaning component is detachably installed on the stiffening plate.

[0015] As one possible implementation of the above-mentioned feeder lifting belt rake nail cleaning device, the stiffener plate is provided with a mounting groove, and the cleaning component is fixed in the mounting groove by bolts or buckle structure, and the extension length of the cleaning component is adjustable.

[0016] As one possible implementation of the above-mentioned feeder lifting belt rake nail cleaning device, the cleaning component is a brush or a scraper.

[0017] As one possible implementation of the above-mentioned feeder elevator belt rake nail cleaning device, the feeder elevator belt rake nail cleaning device also includes a tensioning component connected to the bracket, and the tensioning component is configured to adjust the tension force acting on the driven wheel and the driving wheel by the transmission component.

[0018] As one possible implementation of the above-mentioned feeder lifting belt rake nail cleaning device, the tensioning assembly includes a first support and a tensioning wheel. The first support is fixedly connected to the bracket, and the tensioning wheel is rotatably connected to the first support via a rotating shaft. The first support is provided with an oblong hole, and the rotating shaft is movably disposed in the oblong hole and can be fixed relative to the first support.

[0019] As one possible implementation of the above-mentioned feeder lifting belt rake nail cleaning device, the driving wheel, the transition wheel and the driven wheel are sprockets, and the transmission component is a chain that cooperates with the chain teeth of the sprockets;

[0020] Alternatively, the driving pulley, intermediate pulley, and driven pulley can be synchronous pulleys, and the transmission component can be a synchronous belt that meshes with the teeth of the synchronous pulleys.

[0021] As one possible implementation of the above-mentioned feeder lifting belt rake nail cleaning device, the surface of the cleaning roller is provided with a wear-resistant layer.

[0022] The beneficial effects of this utility model are:

[0023] This utility model provides a rake nail cleaning device for a feeder lifting belt. During operation, the drive wheel rotates synchronously with the feeder's drive roller under the transmission of a transmission component. The drive wheel then transmits power sequentially to the transition wheel and the driven wheel through the transmission component, causing the cleaning roller to rotate around its own axis. The outer peripheral wall of the cleaning roller is provided with multiple ribs spaced axially, with the gaps between adjacent ribs corresponding to the rake nails on the conveyor belt. When the feeder conveyor belt is running, the rake nails move with the conveyor belt and pass through the gaps between the ribs. At this time, the rotating ribs and the surface of the rake nails generate frictional contact, and the material such as tobacco leaves and tobacco dust adhering to the rake nails is peeled off through mechanical scraping. The transition wheel allows adjustment of the tension and direction of the transmission path, ensuring that the rotation speed of the cleaning roller and the drive roller are matched, so that the rotation direction of the drive roller is opposite to that of the cleaning roller. This makes the cleaning action of the ribs on the rake nails continuous and stable, thereby effectively cleaning the tobacco leaves adhering to and hanging on the rake nails, improving the cleaning effect.

[0024] The one-to-one correspondence between the ribs and the rake nails ensures that each rake nail can be precisely cleaned, avoiding cleaning dead spots caused by misalignment. The ribs act directly on the surface of the rake nails through rotational friction, which can efficiently remove tobacco leaves that are stuck due to high temperature and humidity and strong adhesion, reducing the amount of material carried back on the rake nails. This allows the removed material to fall directly into subsequent processes, reducing material loss and improving raw material utilization.

[0025] This device achieves fully automatic cleaning through active roller drive, requiring no additional power source. It can complete the cleaning operation simultaneously during the normal operation of the feeder, eliminating manual operation and significantly reducing labor costs. At the same time, it avoids production interruptions caused by machine downtime for cleaning, ensuring the continuous and stable operation of the filament making process and improving production continuity.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] like Figure 1-3As shown, an embodiment of this utility model provides a scraping device for a feeder conveyor belt rake nails, including a bracket, a drive wheel 2, a scraping roller 7, a driven wheel 4, and a transition wheel 6. The bracket is positioned below the drive roller 1 of the feeder. The drive wheel 2 is coaxially and fixedly connected to the drive roller 1 of the feeder. The scraping roller 7 is rotatably connected to the bracket, and its axial direction is parallel to and spaced apart from the axial direction of the drive roller 1. A scraping assembly is provided on the outer peripheral wall of the scraping roller 7. The scraping assembly includes multiple stiffeners 8, which are spaced apart along the axial direction of the scraping roller 7. The gap between adjacent stiffeners 8 corresponds one-to-one with the rake nails on the feeder conveyor belt, and the gap is used for the rake nails to pass through so that the stiffeners 8 can scrape the material on the rake nails. The driven wheel 4 is coaxially and fixedly connected to the scraping roller 7. The transition wheel 6 is rotatably connected to the bracket and located below the driven wheel 4. The axial direction of the transition wheel 6 is parallel to and spaced apart from the axial direction of the driven wheel 4. The drive wheel 2 is sequentially connected to the transition wheel 6 and the driven wheel 4 via a transmission component 3.

[0035] When the feeder's lifting belt rake cleaning device is working, the drive wheel 2 first rotates synchronously with the feeder's drive roller 1 under the transmission action of the transmission component 3. The drive wheel 2 transmits power sequentially to the transition wheel 6 and the driven wheel 4 through the transmission component 3, driving the cleaning roller 7 to rotate around its own axis. The outer peripheral wall of the cleaning roller 7 is provided with multiple ribs 8 distributed axially at intervals, and the gaps between adjacent ribs 8 correspond one-to-one with the rakes on the conveyor belt. When the feeder's conveyor belt is running, the rakes move with the conveyor belt and pass through the gaps between the ribs 8. At this time, the rotating ribs 8 make frictional contact with the surface of the rakes, and the tobacco leaves, tobacco dust, and other materials adhering to the rakes are peeled off through mechanical scraping. The setting of the transition wheel 6 can adjust the tension and direction of the transmission path to ensure that the rotation speed of the cleaning roller 7 and the drive roller 1 are matched, so that the rotation direction of the drive roller 1 is opposite to the rotation direction of the cleaning roller 7, making the cleaning action of the ribs 8 on the rakes continuous and stable, thereby effectively cleaning the tobacco leaves adhering to and hanging on the rakes and improving the cleaning effect.

[0036] By ensuring a one-to-one correspondence between the ribs 8 and the rake nails, each rake nail can be precisely cleaned, avoiding cleaning dead spots caused by misalignment. The ribs 8 act directly on the surface of the rake nails through rotational friction, which can efficiently peel off the tobacco leaves that remain due to high temperature and humidity and strong adhesion, reducing the amount of material carried back on the rake nails, allowing the peeled material to fall directly into subsequent processes, reducing material loss and improving raw material utilization.

[0037] The device achieves fully automatic cleaning through the drive of the active roller 1, without the need for an additional power source. It can complete the cleaning operation simultaneously during the normal operation of the feeder, eliminating the need for manual operation, significantly reducing labor costs, and avoiding production interruptions caused by machine downtime for cleaning. This ensures the continuous and stable operation of the filament making process and improves production continuity.

[0038] Understandably, the spacing of the stiffener plate 8 can be customized according to the arrangement of the rake nails, and it can be adapted to various specifications of lifting belt rake nails. There is no need to modify the main structure of the feeder, which makes it highly practical and compatible.

[0039] For example, the driving wheel 2, the intermediate wheel 6, and the driven wheel 4 are sprockets, and the transmission component 3 is a chain that meshes with the teeth of the sprockets. The sprockets and the chain transmit power through tooth meshing, without elastic slippage or slippage, and the transmission ratio is precise and constant, ensuring the synchronization of the sweeping action.

[0040] In other embodiments, the driving wheel 2, the transition wheel 6, and the driven wheel 4 may also be synchronous wheels, and the transmission component 3 is a synchronous belt that meshes with the teeth of the synchronous wheel.

[0041] Furthermore, multiple cleaning components are provided, and the multiple cleaning components are distributed along the circumference of the cleaning roller 7.

[0042] Multiple cleaning components (i.e., multiple sets of ribs 8) are distributed circumferentially around the cleaning roller 7, forming "multiple lines of defense." When the rake passes through the gaps between the ribs 8, the ribs 8 at different circumferential positions can contact the rake surface from different angles, repeatedly scraping areas prone to material accumulation, such as the sides and roots of the rake. For example, the circumferentially distributed ribs 8 can separately peel off residual material on the front, back, and top sides of the rake, avoiding the problem of material residue after a single cleaning. This is especially suitable for tobacco containing sticky sugars or for strongly adhering materials in humid environments, greatly improving cleaning coverage. The circumferential distribution of multiple cleaning components can distribute the cleaning load to each set of ribs 8, reducing the contact pressure between a single set of ribs 8 and the rake, reducing wear such as edge curling of the ribs 8 and rake bending caused by long-term friction, and extending the service life of the components.

[0043] For example, such as Figure 1 As shown, six groups of cleaning components are provided. In other embodiments, the cleaning components may also be provided in two, three, four or more groups.

[0044] Furthermore, each stiffener 8 is provided with a cleaning element on the side near the adjacent stiffener 8. The cleaning element is used to clean the material on the rake nails passing through the corresponding gap. Optionally, the cleaning element is a brush or a scraper.

[0045] Preferably, the cleaning component is made of an elastic material, specifically, a nylon brush or a rubber scraper.

[0046] The cleaning component can fill the tiny gaps between the stiffening plate 8 and the rake nail, and perform deep cleaning of the grooves, weld points and other structural dead corners on the surface of the rake nail. For example, tobacco rake nails often have edge burrs due to the welding process. Traditional stiffening plate rigid scraping can easily cause material to accumulate at the burrs, while the flexible cleaning component can deform with the contour of the rake nail and fit its surface uneven structure to completely remove residual tobacco dust, broken shreds and other fine materials.

[0047] Furthermore, the cleaning component is detachably installed on the stiffening plate 8.

[0048] As a vulnerable component that directly contacts the rake, the sweeping parts will experience wear and aging (such as rubber cracking and bristle flattening) after long-term use. Specifically, by adopting a detachable structure such as bolt connection, snap-fit ​​fixing or magnetic attraction, worn parts can be quickly disassembled and replaced. The failed sweeping parts can be replaced separately without disassembling the rib plate 8 and the entire sweeping roller 7, which greatly saves spare parts costs and reduces maintenance costs.

[0049] Specifically, the stiffener plate 8 has an installation groove, and the cleaning component is fixed in the installation groove by bolts or a snap-fit ​​structure, and the extension length of the cleaning component is adjustable.

[0050] The extension length of the cleaning component can be adjusted by tightening or loosening the bolts or by using the snap-lock positioning slot (e.g., each adjustment of 1mm is one level). This allows for dynamic compensation based on the wear level of the cleaning component, extending its effective service life and avoiding the waste of replacing the entire component due to localized wear. It is also suitable for different wear stages.

[0051] Furthermore, the feeder lifting belt rake nail cleaning device also includes a tensioning component 5, which is connected to the bracket and is configured to adjust the tension force of the transmission component 3 acting on the driven wheel 4 and the driving wheel 2.

[0052] The tensioning assembly 5 adjusts the tension of the transmission component 3 to prevent problems such as tooth skipping, slippage, or abnormal noise caused by the slackness of the transmission component 3. For example, when the transmission component 3 wears and stretches after the feeder has been running for a long time, the tensioning assembly 5 adjusts the tension to ensure that the transmission ratio of the drive wheel 2, the transition wheel 6, and the driven wheel 4 remains constant, so that the rotational speed of the cleaning roller 7 matches the running speed of the conveyor belt, and avoids incomplete cleaning caused by fluctuations in the relative motion speed of the stiffener 8 and the rake nail.

[0053] Specifically, the tensioning assembly 5 includes a first support 10 and a tensioning wheel 13. The first support 10 is fixedly connected to the bracket, and the tensioning wheel 13 is rotatably connected to the first support 10 via a rotating shaft 11. The first support 10 is provided with an oblong hole, and the rotating shaft 11 is movably disposed in the oblong hole and can be fixed relative to the first support 10.

[0054] like Figure 2 As shown, one end of the rotating shaft 11 is rotatably connected to the tensioning wheel 13 through the first bearing 12, and the other end of the rotating shaft 11 passes through the waist-shaped hole of the first support 10 and is threadedly connected to the first nut 9, thereby fixing the position of the tensioning wheel 13 relative to the bracket.

[0055] The tension wheel 13 is installed in the oblong hole of the first support 10 through the rotating shaft 11. The length of the oblong hole provides linear adjustment space for the rotating shaft 11. The position of the tension wheel 13 can be steplessly adjusted according to the wear and elongation of the chain, so that the chain sag is always controlled within the optimal range, ensuring that the meshing depth between the chain and the sprocket is constant, and avoiding skipping teeth due to insufficient tension or chain breakage due to excessive tension.

[0056] like Figure 3 As shown, the transition wheel assembly includes a transition wheel 6, a second support 14, and a second bearing 15. The second support 14 is fixedly connected to the bracket, and a connecting rod is fixedly connected to the second support 14. The connecting rod is rotatably connected to the transition wheel 6 through the second bearing 15.

[0057] Optionally, the second support 14 is provided with an oblong hole, and the connecting rod is movably disposed in the oblong hole and threadedly connected to the second nut so that the position of the transition wheel 6 can be fixed relative to the second support 14.

[0058] Optionally, the surface of the cleaning roller 7 is provided with a wear-resistant layer. Specifically, the wear-resistant layer can be a tungsten carbide coating or a wear-resistant alloy steel layer.

[0059] The cleaning roller 7 is subject to long-term friction with rake nails and tobacco leaves, which can easily cause wear marks and dents on the roller surface, shortening its service life. Tungsten carbide coating or wear-resistant alloy steel layer can increase the surface hardness by 3-5 times and the wear resistance by 10-20 times, greatly extending the service life of the cleaning roller 7, reducing the replacement frequency, and significantly reducing maintenance costs.

[0060] Optionally, baffles are provided at both ends of the cleaning roller 7. The diameter of the baffles is larger than the distribution diameter of the rib plate 8, in order to prevent material from falling to both ends of the cleaning roller 7 during the cleaning process.

[0061] 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.
