Description

Technical Field

[0001] This invention relates to the field of tobacco equipment cleaning technology, and more specifically, to a portable device for cleaning tobacco residue from the rake nails of a cigarette making line elevator. Background Technology

[0002] In the cigarette manufacturing process, the elevator is a key auxiliary device used to transport tobacco shreds, tobacco sheets, and other materials between different processes. It supports and transports materials during the lifting process by using several rakes installed at equal intervals on a ring belt. Since tobacco materials themselves contain a certain amount of moisture, sugar, and oil, after long-term continuous operation, these components will gradually adhere to and accumulate on the surface and roots of the elevator rakes, forming a hard and sticky layer of tobacco grime. If this accumulated grime is not removed in a timely and effective manner, it may fall off after reaching a certain thickness and mix into the clean tobacco materials being transported, causing serious impurity contamination and directly affecting the quality and safety of cigarette products.

[0003] Currently, the cleaning of soot from the rake nails of elevators is generally done manually. Operators must climb inside the equipment after it has stopped, using simple tools (such as shovels, scrapers, and rags) to manually tap, scrape, and wipe each rake nail. However, a single elevator typically has hundreds or even thousands of rake nails, making this method extremely labor-intensive. Cleaning one elevator often takes up to a full workday, severely restricting production pace and equipment utilization. Furthermore, operators must work at height in confined spaces, posing significant safety risks. The effectiveness of manual cleaning is inconsistent, making it difficult to guarantee the required cleanliness. While some technical solutions have attempted to improve this, such as a fixed automatic cleaning device installed on the elevator that uses a cleaning rack with cleaning troughs and brushes to clean the rake nails, these devices are typically complex in structure and inconvenient to install. The cleaning racks are either fixed or simply reciprocating, limiting the cleaning power and coverage, making them unsuitable for different working conditions and stubborn soot removal needs.

[0004] In summary, existing manual cleaning methods suffer from inherent drawbacks such as low efficiency, time-consuming and labor-intensive processes, poor safety, and unstable cleaning results; while existing automated cleaning solutions suffer from problems such as complex structures, insufficient adaptability, and limited cleaning capabilities. Therefore, to solve the above technical problems, this application proposes a portable cigarette making line elevator rake nail cleaning device. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a portable cigarette making line lifting machine rake nail cleaning device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a portable cigarette making line lifting machine rake nail cleaning device, comprising: The movable box has a bottom-opening structure and is used to cover the top of the rake nail of the cigarette making line elevator. The surface of the movable box has several rectangular openings that pass through it at equal intervals. A rotating cleaning mechanism is disposed inside the movable box, including at least one drive motor and at least one set of cleaning units driven to rotate by the drive motor. Each set of cleaning units includes two adjacent rotating tubes with cleaning bristles on their surfaces. The cleaning bristles are used to clean rake nails passing through the rectangular opening when the rotating tubes rotate. A negative pressure collection assembly, which is disposed on the movable box, is used to generate negative pressure during the cleaning process to collect the stripped soot. A walking drive assembly, which is disposed on the moving box, is used to drive the moving box to move along the inner wall of the elevator.

[0007] Preferably, the rotating cleaning mechanism includes multiple sets of cleaning units arranged along the extension direction of the moving box, and the rotating tubes of all the cleaning units are connected to the output end of the drive motor through a gear transmission unit to achieve synchronous driving.

[0008] Preferably, the gear transmission unit includes: A rectangular cavity is provided inside the top box of the mobile box; Each cleaning unit is provided with a first gear pair, and each first gear pair includes two first gears that are respectively fixed on the two rotating tubes and mesh with each other; A linkage gear set is provided between two adjacent cleaning units, which includes a connecting shaft and a second gear fixed on the connecting shaft. The second gear simultaneously meshes with one of the first gears at a corresponding position in the two adjacent cleaning units. And a power input shaft, which is driven by the drive motor and meshes with the first gear in one of at least a set of the cleaning units via at least one third gear.

[0009] Preferably, the top of the mobile box is also provided with a negative pressure chamber that communicates with the rectangular cavity, the rotating tube is a hollow tube, its top end is communicated with the negative pressure chamber, and a dust suction hole is provided on the tube wall.

[0010] Preferably, the negative pressure collection component includes: A collection box is provided on the mobile box; A vacuum pipe connects the collection box to the negative pressure chamber; And the fan blades, whose rotation can generate negative pressure in the collection box and the connected negative pressure chamber.

[0011] Preferably, the fan blades are driven by the gear transmission unit, and the power input shaft drives a horizontal shaft coaxially connected to the fan blades to rotate via a bevel gear pair.

[0012] Preferably, the output end of the drive motor is provided with a first bevel gear, and the power input shaft is a rotating shaft with a second bevel gear meshing with the first bevel gear at its top end; The horizontal axis is provided with a third bevel gear that meshes with the second bevel gear.

[0013] Preferably, the walking drive assembly includes at least four walking units arranged in a rectangular array, each walking unit comprising: A mounting plate fixed to the mobile box; Hydraulic rods mounted on the mounting plate; Mounting frame driven by the hydraulic rod; And a rubber wheel that is rotatably mounted within the mounting frame and driven by a synchronous motor.

[0014] Preferably, the mobile box also integrates a mobile power supply box and a controller. The mobile power supply box contains a charging power source, and the controller is used to control the operation of the walking drive component, the rotating cleaning mechanism, and the negative pressure collection component.

[0015] Preferably, the inner wall of the rectangular opening is provided with a low-temperature plasma emitter for pre-treating soot.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, by designing the rotating tube as a hollow structure and opening a dust suction hole, with its top end connected to the negative pressure chamber, this structure allows the dust suction hole near the cleaning bristles to generate a negative pressure airflow while the cleaning bristles rotate and peel off the soot, instantly sucking in and collecting the freshly peeled soot fragments. This design achieves synchronization of cleaning and collection in terms of action and position, effectively reducing the flying and secondary adhesion of soot in the work area, maintaining the cleanliness of the work environment, and preventing dirt from clogging the bristles themselves, thereby maintaining the stability and continuity of the cleaning effect.

[0017] 2. In this invention, the walking drive component can drive the rubber wheel to press against the inner wall of the elevator through the hydraulic rod. While providing the moving power, it also realizes the stable positioning and guidance of the device. Under this condition, the device can move smoothly along the inner wall of the elevator, so that the equidistantly arranged rakes pass through the cleaning area composed of multiple sets of cleaning units in sequence. On the one hand, this realizes continuous and automated cleaning of a large number of rakes, which significantly improves the work efficiency; on the other hand, the stable positioning and walking ensure the consistency of the contact relationship between the cleaning bristles and the rakes, thereby ensuring the uniformity and reliability of the cleaning effect throughout the line.

[0018] 3. In this invention, the drive motor drives the rotating tubes of all cleaning units and the suction fan blades simultaneously through the same set of gear transmission units and bevel gear pairs. This single power source and mechanical linkage design ensures that the speed ratio of the cleaning action and the negative pressure collection action is fixed and the start and stop are completely synchronized. This not only simplifies the control system and reduces costs and failure risks, but also ensures the automatic matching of cleaning intensity and suction power from a structural perspective, so that the device can operate in coordination under different working conditions and avoids the functional imbalance problem that may occur with independent drive.

[0021] like Figures 1-8 As shown, the present invention provides a portable cigarette making line elevator rake nail cleaning device, comprising: The movable box 100 has a bottom-opening structure and is used to cover the top of the rake nail of the cigarette making line elevator. The surface of the movable box 100 has several rectangular openings 200 that are equidistant from each other. The inner sidewall of the rectangular opening 200 is provided with a low-temperature plasma emitter for pre-treating tobacco residue. This technology is not described in detail here and is not shown in the figure. It should be noted that the mobile box 100 constitutes the portable main body and working chamber of the device. It is designed as a box structure with an open bottom, which makes it easy to cover the area of ​​the hoist rake nails to be cleaned from top to bottom. The side wall (or the transition area between the top and the side wall) of the mobile box 100 is provided with several rectangular openings 200 at equal intervals. The spacing of these openings matches the pitch of the hoist rake nails to ensure that the rake nails can pass through smoothly. In a preferred embodiment, a low-temperature plasma emitter (not shown in the figure) can also be optionally installed on the inner side wall of the rectangular opening 200. When the device is working, the plasma emitter can act on the soot on the surface of the rake nails in advance. Through its oxidation decomposition and surface activation effect, it can effectively soften the carbonized sugar and oil components, significantly reducing the resistance of subsequent mechanical cleaning. The bottom edge of the mobile box 100 is also provided with two sets of symmetrical metal balls (not shown in the figure) to provide auxiliary support and sliding when the device is placed in the hoist, which facilitates the initial positioning.

[0022] A rotating cleaning mechanism (300) is disposed inside a movable box (100) and includes at least one drive motor (303) and at least one set of cleaning units driven to rotate by the drive motor (303). Each set of cleaning units includes two adjacent rotating tubes (301) with cleaning bristles (302) on their surfaces. The cleaning bristles (302) are used to clean the rake nails passing through the rectangular opening (200) when the rotating tubes (301) rotate. The rotating cleaning mechanism (300) includes multiple sets of cleaning units arranged along the extension direction of the movable box (100), and the rotating tubes (301) of all cleaning units are connected to the output end of the drive motor (303) through a gear transmission unit to achieve synchronous driving. The gear transmission unit includes: A rectangular cavity (304) is provided in the top box of the mobile box (100); a first gear pair is provided for each cleaning unit, each first gear pair includes two first gears (306) respectively fixed on two rotating tubes (301) and meshing with each other; a linkage gear set is provided between two adjacent cleaning units, which includes a connecting shaft (307) and a second gear (308) fixed on the connecting shaft (307), the second gear (308) meshing with a first gear (306) at a corresponding position in the two adjacent cleaning units; and a power input shaft, which is driven by a drive motor (303) and meshes with a first gear (306) in at least one cleaning unit through at least one third gear (3010); It should be noted that the rotary cleaning mechanism 300 is the core of the cleaning function. It is located on the inner top of the mobile box 100. The mechanism includes a drive motor 303 as a power source, multiple cleaning units, and a set of precision and compact gear transmission units. Each cleaning unit includes two parallel and adjacent rotating tubes 301. Cleaning bristles 302 are fixed to the surface of the rotating tubes 301 in a circumferential array. The cleaning bristles 302 are preferably connected to the rotating tubes 301 by bolts for easy replacement after wear. The cleaning bristles 302 on the two rotating tubes 301 in the same group are staggered in the circumferential direction to ensure that the rake nails can be brushed without dead angles. To improve the cleaning effect, in a further optimized embodiment, several micro airflow holes (not shown in the figure) can be opened in the gaps between the cleaning bristles 302 of each group of rotating tubes 301 along the circumferential array for connecting a micro high-pressure air pump (existing technology, not described in detail here). The compressed air sprayed during operation can help blow off stubborn dirt layers that are difficult for the bristles to peel off and prevent dirt from accumulating on the bristles.

[0023] The gear transmission unit is used to synchronously and efficiently transmit the power of a single drive motor 303 to all rotating tubes 301, and to ensure that the two rotating tubes 301 in each group rotate in opposite directions. This unit is mainly integrated in a rectangular cavity 304 opened in the top box of the mobile box 100. Specifically, in each cleaning unit, the top ends of the two rotating tubes 301 extend into the rectangular cavity 304, and a first gear 306 is fixed thereon. The two first gears 306 mesh with each other to form a first gear pair, thereby ensuring that the two rotating tubes 301 in the same group rotate in opposite directions. In order to transmit power between adjacent cleaning units, a connecting shaft 307 is rotatably arranged in the rectangular cavity 304, located between two adjacent groups of cleaning units. A second gear 308 is fixed on the connecting shaft 307. The second gear 308 simultaneously meshes with a first gear 306 at a corresponding position (e.g., both on the left or right side) in two adjacent sets of cleaning units, thereby forming a linkage gear set. The power input is provided by a rotating shaft 309, which is also rotatably disposed in the rectangular cavity 304. At least one third gear 3010 is fixed on its surface. The third gear 3010 meshes with a first gear 306 in at least one set of cleaning units (e.g., the first gear 306 on the right in the rightmost set), thereby introducing power into the entire gear transmission unit. To drive the rotating shaft 309, a connecting box 3011 is fixed on the upper surface of the movable box 100. The drive motor 303 is fixed to the side of the connecting box 3011, and its output shaft extends into the connecting box 3011 and is equipped with a first bevel gear 3012. The top end of the rotating shaft 309 extends into the connecting box 3011 and is equipped with a second bevel gear 3013 that meshes perpendicularly with the first bevel gear 3012. Thus, the power of the drive motor 303 is transmitted to the rotating shaft 309 through the first bevel gear 3012 and the second bevel gear 3013, and then through the gear network composed of the third gear 3010, the first gear 306 and the second gear 308, ultimately driving all rotating tubes 301 to rotate synchronously and in opposite directions.

[0024] A negative pressure collection component (400) is installed on the mobile box (100) to generate negative pressure during the cleaning process to collect the peeled grime; the top of the mobile box (100) is also provided with a negative pressure chamber (305) that communicates with the rectangular cavity (304), and the rotating tube (301) is a hollow tube body, the top of which communicates with the negative pressure chamber (305), and a dust suction hole (406) is opened on the tube wall. The negative pressure collection assembly (400) also includes: A collection box (401) is mounted on a movable box (100); a suction pipe (405) connects the collection box (401) to a negative pressure chamber (305); and a suction fan blade (4010), the rotation of which generates negative pressure in the collection box (401) and the connected negative pressure chamber (305). The suction fan blade (4010) is driven by a gear transmission unit, and the power input shaft drives a horizontal shaft (409) coaxially connected to the suction fan blade (4010) to rotate through a bevel gear pair. The output end of the drive motor (303) is provided with a first bevel gear (3012), and the power input shaft is a rotating shaft (309), the top of which is provided with a second bevel gear (3013) meshing with the first bevel gear (3012); a third bevel gear (4011) meshing with the second bevel gear (3013) is provided on the horizontal shaft (409). It should be noted that the negative pressure collection component 400 is used to collect the soot and debris that are detached during the cleaning process in real time, keeping the working environment clean and preventing secondary pollution. This component is highly coordinated with the rotating cleaning mechanism 300 in terms of structure and power. First, at the top of the mobile box 100, there is a negative pressure chamber 305 that communicates with the rectangular cavity 304. All rotating tubes 301 are hollow tubes with their top ends communicating with the negative pressure chamber 305. Multiple dust suction holes 406 are opened along the circumference on the tube wall, which allows air suction to be formed inside the rotating tube 301 and near the dust suction holes 406. The main body of the collection component 400 is a collection box 401 fixed to the upper surface of the mobile box 100. The collection box 401 contains a detachable dust collection bag 402 for holding the collected ash. The side of the collection box 401 has an ash inlet and is connected to the negative pressure chamber 305 through a suction pipe 405. The top of the collection box 401 is hinged to a sealing door panel 403. The sealing door panel 403 is provided with a handle 404 for easy opening and closing to replace or clean the dust collection bag 402. To generate a continuous negative pressure in the collection box 401 and the negative pressure chamber 305, this device is designed with an air extraction system driven by the cleaning mechanism. Specifically, an installation tube 407 is embedded on the side wall of the collection box 401 away from the suction pipe 405. Two parallel ventilation mesh discs 408 are fixed to the inner wall of the installation tube 407 for protection and guidance of airflow. A horizontal shaft 409 is rotatably supported between the two ventilation mesh discs 408. A suction fan blade 4010 is installed on a section of the horizontal shaft 409 inside the installation tube 407. One end of the horizontal shaft 409 extends into the interior of the connecting box 3011 and a third bevel gear 4011 is fixed at the end. The third bevel gear 4011 meshes with the second bevel gear 3013 of the driving shaft 309. Therefore, when the drive motor 303 is working, it not only drives all the cleaning brush bristles to rotate, but also drives the third bevel gear 4011 and the horizontal shaft 409 to rotate through the second bevel gear 3013, thereby driving the suction fan blade 4010 to rotate. The rotation of the suction fan blade 4010 draws out the air in the collection box 401, creating a negative pressure inside it and inside the negative pressure chamber 305 and the rotating tube 301. The soot and debris that the cleaning brush bristles 302 peel off from the rake are sucked into the rotating tube 301 through the suction hole 406 under the action of negative pressure, and then through the negative pressure chamber 305 and the suction tube 405, and finally collected in the dust collection bag 402 of the collection box 401.

[0025] A travel drive assembly (500), disposed on the movable box (100), is used to drive the movable box (100) to move along the inner wall of the hoist. The travel drive assembly (500) includes at least four travel units arranged in a rectangular array, each travel unit including: Mounting plate (501) fixed on the movable box (100); hydraulic rod (502) mounted on mounting plate (501); mounting frame (503) driven by hydraulic rod (502); and rubber wheel (504) rotatably disposed in mounting frame (503) and driven by synchronous motor (505). It should be noted that the walking drive assembly 500 enables the entire device to move autonomously inside the hoist, thereby cleaning all the rake nails in sequence. The assembly includes at least four walking units arranged in a rectangular array on the upper surface of the moving box 100. Each walking unit includes: a mounting plate 501 fixed to the moving box 100; a hydraulic rod 502 vertically mounted on the mounting plate 501; a mounting frame 503 driven by the telescopic rod end of the hydraulic rod 502; and a rubber wheel 504 rotatably mounted in the mounting frame 503 via bearings. A synchronous motor 505 is also fixed on the upper surface of the mounting frame 503 for driving the rubber wheel 504 to rotate. The working process is as follows: After the device is placed in the hoist, all hydraulic rods 502 are extended synchronously, pushing the mounting frame 503 and rubber wheels 504 outward until the four rubber wheels 504 are firmly pressed against the inner walls on both sides of the hoist, thus fixing and centering the device. During cleaning operations, all synchronous motors 505 are started, driving the rubber wheels 504 to rotate synchronously in the same direction, which propels the entire device to move smoothly along the inner wall of the hoist, achieving automated continuous cleaning.

[0026] The mobile box (100) also integrates a mobile power supply box (600) and a controller (700). The mobile power supply box (600) is equipped with a charging power supply, and the controller (700) is used to control the operation of the walking drive component (500), the rotating cleaning mechanism (300) and the negative pressure collection component (400). To achieve portability and integrated operation, a mobile power supply box 600 and a controller 700 are also integrated on the upper surface of the mobile case 100. The mobile power supply box 600 is equipped with a high-capacity rechargeable battery as the driving power for the device. The controller 700 integrates the necessary control circuits and interfaces for unified control of the start-up and coordinated operation of the drive motor 303, various synchronous motors 505, hydraulic rod 502, and optional components such as low-temperature plasma emitter and miniature high-pressure air pump (the control logic of the mobile power supply 600 and the controller 700 are existing technologies and will not be described in detail here).

[0027] Working principle: First, place the device inside the hoist, allowing the rake nail to pass through the rectangular opening 200 into the movable box 100. Start the walking drive assembly 500 via the controller 700, extending the hydraulic rod 502 to press the rubber wheel 504 tightly against the machine wall fixing device; Subsequently, the drive motor 303 is started. The drive motor 303 drives the rotating tubes 301 and brush bristles 302 of all cleaning units to rotate at high speed in opposite directions through the bevel gear pair and gear transmission unit, so as to vigorously scrub the rake nails that have passed through. On the other hand, the suction fan blades 4010 are driven to rotate by the same set of bevel gear pairs (second bevel gear 3013 and third bevel gear 4011), creating negative pressure in the collection box 401 and negative pressure chamber 305, which sucks away and collects the tobacco residue that has been brushed off in real time. Subsequently, the controller 700 controls the synchronous motor 505 of the walking drive assembly 500 to work, and the drive device moves along the elevator at a constant speed, so that the subsequent rakes enter the cleaning station in sequence until the cleaning of all the rakes on the entire line is completed. Throughout the process, the three major functions of cleaning, collection, and movement are carried out automatically and in tandem, greatly improving cleaning efficiency, effectiveness, and operational safety.

[0028] In summary: The effect of real-time synergy between cleaning and collection: The present invention designs the rotating tube 301 as a hollow structure and opens a dust suction hole 406, so that its top end is connected to the negative pressure chamber 305. This structure allows the cleaning bristles 302 to generate negative pressure airflow at the nearby dust suction hole 406 while rotating to peel off the soot, so that the freshly peeled soot debris can be sucked in and collected immediately. This design realizes the synchronization of cleaning and collection in terms of action and position, effectively reducing the flying and secondary adhesion of soot in the work area, maintaining the cleanliness of the work environment, and avoiding the clogging of the bristles by dirt, thereby maintaining the stability and continuity of the cleaning effect. The effect of continuous synergy between walking and cleaning: The walking drive component 500 of the present invention can drive the rubber wheel 504 to press against the inner wall of the elevator through the hydraulic rod 502, which provides the power for movement and realizes the stable positioning and guidance of the device. Under this condition, the device can move smoothly along the inner wall of the elevator, so that the equidistantly arranged rakes pass through the cleaning area composed of multiple cleaning units in sequence. On the one hand, this realizes continuous and automated cleaning of a large number of rakes, which significantly improves the work efficiency; on the other hand, the stable positioning and walking ensure the consistency of the contact relationship between the cleaning bristles and the rakes, thereby ensuring the uniformity and reliability of the cleaning effect throughout the line. Effects of power integration and synchronization: The drive motor 303 of this invention drives the rotating tube 301 of all cleaning units and the suction fan blades 4010 simultaneously through the same set of gear transmission units and bevel gear pairs 3012, 3013, 4011. This single power source and mechanical linkage design ensures that the speed ratio of cleaning action and negative pressure collection action is fixed and the start and stop are completely synchronized. This not only simplifies the control system and reduces costs and failure risks, but also ensures automatic matching of cleaning intensity and suction power from a structural perspective, so that the device can operate in coordination under different working conditions and avoids the functional imbalance problems that may occur with independent drive.
