Technical Field
[0001] This utility model relates to the field of tobacco processing technology, and in particular to a multifunctional maintenance tool for the cigarette industry. Background Technology
[0002] In cigarette manufacturing workshops, vibrating conveyors are widely used as important auxiliary equipment. The rocker arms connecting the trough and the balancer on these conveyors are prone to wear during operation, especially the rubber strips within the rocker arms, which lose elasticity over time. This reduces the vibration amplitude of the trough, leading to uneven material transport and potential blockages. Typically, cigarette manufacturing workshops use dozens to hundreds of vibrating conveyors, with each conveyor having anywhere from a dozen to forty rocker arms. Therefore, replacing the rubber strips within the rocker arms would significantly reduce the cost of replacing the entire rocker arm.
[0003] Currently, there is no good tooling for replacing rocker arm rubber strips, and it is difficult to replace rocker arm rubber strips manually without the aid of special tooling. At the same time, when disassembling bearing components, it is difficult to disassemble them when there is abnormal wear or tight fit.
[0004] Therefore, a multifunctional maintenance tool for the cigarette industry is designed to effectively solve the above-mentioned problems. Utility Model Content
[0005] To overcome the shortcomings of existing technologies, such as the lack of suitable tooling for replacing rocker arm rubber strips, which makes it difficult to replace rocker arm rubber strips manually without specialized tooling; and the difficulty in disassembling bearing components when abnormal wear or tight fit occurs, this utility model provides a multi-functional maintenance tooling for the cigarette industry.
[0006] The technical implementation scheme of this utility model is as follows: a multifunctional maintenance tool for the cigarette industry, comprising: Work platform; Compaction and pull-out mechanisms, including: Several support rods are provided, all of which are vertically arranged above the working platform; A support platform is disposed on top of several of the aforementioned support rods; An adjusting nut is fixedly installed in the middle of the support platform; A hydraulic rod is vertically inserted through the middle of the support platform, and its outer side is threaded into the inner side of the adjusting nut. A hydraulic handle is rotatably mounted at the top of the hydraulic rod; The limiting assembly includes an adjustable limiting mechanism for adjusting the position of the workpiece along the longitudinal direction of the work platform, and a fixed limiting mechanism for clamping and fixing the workpiece in cooperation with the adjustable limiting mechanism. The adjustable limiting mechanism is disposed at one end of the work platform, and the fixed limiting mechanism includes at least one set of fixing frames that can be detachably installed on the work platform. This device provides a portable operating platform, precisely positioning and firmly fixing rocker arms or other workpieces of different specifications at preset through-hole positions on the platform through the synergistic action of limiting components. Using a compaction and pulling mechanism, combined with coarse adjustment of the hydraulic rod height and the drive of the hydraulic handle, it performs efficient compression removal or installation operations on the rocker arm rubber strip assembly fixed at the through-hole, or disassemblies and assembles other workpieces fixed on the platform. Furthermore, the tooling function can be expanded through the addition of adjustable pull claws, enabling the suspension, fixing, and hydraulic pulling operations of irregularly shaped parts.
[0007] Preferably, the adjustable limiting mechanism includes a fixed plate fixed to one end of the working platform, an adjusting rod passing through the middle of the fixed plate and threadedly engaged with the fixed plate, and an adjusting baffle rotatably connected to the end of the adjusting rod. Rotating the adjusting rod can drive the adjusting baffle to move longitudinally along the working platform. It is used to drive the adjusting baffle to move longitudinally along the working platform by rotating the adjusting rod until the adjusting baffle hits one end of the rocker arm and fixes the rocker arm.
[0008] Preferably, the fixing frame of the fixing limiting mechanism is provided in two sets, and both ends of each set of fixing frames are detachably fixed to the preset installation position at the other end of the working platform by bolts.
[0009] Preferably, the surface of the working platform has a through hole, the position of which corresponds to the rocker arm rubber strip mounting position fixed below the hydraulic rod; The through hole is used to provide a channel for the hydraulic rod to press the new rubber strip down or push the old rubber strip up during the rocker arm rubber strip replacement operation, so that the rubber strip can smoothly enter or exit the rocker arm mounting slot.
[0010] Preferably, the support platform is also provided with symmetrical sliding grooves at both ends, and one end of the pull claw is slidably provided in each sliding groove, with the extension direction of the claw being coaxial with the hydraulic rod; Pull claws are used to hook the claws of bearings into the inner or outer ring of the bearing when disassembling components such as bearings, and then disassemble bearing components that are too tight or abnormally worn by means of a hydraulic rod.
[0011] Preferably, the top of the pull claw passes through the slide groove and is provided with an adjusting bolt; After the pull claw moves within the chute, its position is locked on the support platform by tightening the adjusting bolt, ensuring the pull claw is stable and reliable during the pulling operation.
[0012] Preferably, the bottom of the work platform is also provided with wheels and top rods around its perimeter; It is used to facilitate the movement of tooling via wheels, and provides stable support during operation via push rods to prevent tooling from sliding or tipping over.
[0013] Preferably, a pusher frame is also provided on the top of the work platform; Used to provide a point of force application, making it easier for operators to move the tooling.
[0014] Compared with the prior art, the present invention has the following beneficial effects: This utility model solves the problem of the rocker arm being unable to be quickly and accurately positioned and firmly fixed on the operating platform by setting a limiting component consisting of an adjustable limiting mechanism and a fixed limiting mechanism. The adjustable limiting mechanism uses an adjusting baffle to press against one end of the rocker arm, and the fixed limiting mechanism uses a fixing frame to engage the side of the rocker arm. This enables the rapid and precise clamping and fixing of rocker arms of different specifications and sizes, laying the foundation for efficient rubber strip replacement operations in the future. This invention solves the problems of difficult and inefficient manual replacement of rocker arm rubber strips and the difficulty in disassembling interference fit components such as bearings. It achieves smooth, efficient, and labor-saving pressing and ejection of rocker arm rubber strips, as well as powerful static pressure disassembly and installation capabilities for bearing components. This significantly reduces labor intensity and improves maintenance efficiency and success rate. This utility model has a high degree of integration and multiple uses, effectively solving two major maintenance problems in the cigarette industry: rocker arm rubber strip replacement and bearing disassembly. It has the advantages of simple operation, labor saving and high efficiency, reliable fixation, wide applicability and convenient movement, which can significantly reduce maintenance costs and labor intensity, and improve equipment maintenance efficiency.

[0017] like Figures 1 to 5 As shown, this utility model provides a multifunctional maintenance tool for the cigarette industry, comprising: Work platform 1; Compaction and pull-out mechanisms, including: Support rods 2 are provided in several units, all of which are vertically arranged above the working platform 1; A support platform 3 is disposed on top of several of the support rods 2; Adjusting nut 4 is fixedly installed in the middle of the support platform 3; The hydraulic rod 5 is vertically inserted through the middle of the support platform 3, and its outer side is threaded into the inner side of the adjusting nut 4. The hydraulic handle 6 is rotatably mounted on the top of the hydraulic rod 5; The limiting assembly includes an adjustable limiting mechanism 7 for adjusting the position of the workpiece along the longitudinal direction of the work platform 1 and a fixed limiting mechanism for clamping and fixing the workpiece in cooperation with the adjustable limiting mechanism 7. The adjustable limiting mechanism 7 is disposed at one end of the work platform 1, and the fixed limiting mechanism includes at least one set of fixing frames 8 that are detachably installed on the work platform 1. The surface of the work platform 1 is provided with a through hole 9, the position of which corresponds to the rocker arm rubber strip mounting position fixed below the hydraulic rod 5. The support platform 3 is also symmetrically provided with sliding grooves 10 at both ends. One end of a pull claw 11 is slidably provided in each sliding groove 10, and the extension direction of the claw is coaxial with the hydraulic rod 5. The top end of the pull claw 11 passes through the sliding groove 10 and is provided with an adjusting bolt 12. The bottom of the work platform 1 is also equipped with wheels 13 and top rods 14; the top of the work platform 1 is also equipped with a pusher frame 15.
[0018] In a further embodiment, the adjustable limiting mechanism 7 includes a fixed plate 71 fixed to one end of the working platform 1, an adjusting rod 72 passing through the middle of the fixed plate 71 and threadedly engaged with the fixed plate 71, and an adjusting baffle 73 rotatably connected to the end of the adjusting rod 72. Rotating the adjusting rod 72 can drive the adjusting baffle 73 to move longitudinally along the working platform 1. The fixed frame 8 of the fixed limiting mechanism is provided in two sets. Both ends of each set of fixed frames 8 are detachably fixed to the preset installation position at the other end of the working platform 1 by bolts.
[0019] Working principle: When it is necessary to replace the rocker arm rubber strip: First, move the multi-functional maintenance tool to the working position using the wheels 13, and then operate the push rod 14 to make it park stably. In the prior art, the rocker arm is usually in the form of a rectangular strip structure. On its two long sides, there are usually several regularly arranged protrusions or recesses or snap-on designs. These structures are mainly used for the installation and positioning of the rocker arm itself on the vibrating conveyor or for limiting the internal rubber strip assembly. Remove the fixing bracket 8, place the rocker arm whose rubber strip needs to be replaced flat on the work platform 1 with its rectangular bottom surface, and accurately align the part of the rubber strip to be removed with the through hole 9 on the work platform 1.
[0020] Then, reinstall the fixing bracket 8 to the preset installation position on the work platform 1. The fixing bracket 8 is used to form a slot or limiting surface that matches the shape of the rocker arm side. During installation, the slot or limiting surface of the fixing bracket 8 is engaged with the corresponding buckle-shaped protrusion or specific structural part on the side of the rocker arm and tightened with bolts 10 to achieve effective lateral constraint on the rocker arm and prevent it from moving laterally or tilting.
[0021] Next, the adjusting rod 72 of the adjustable limiting mechanism 7 is rotated to drive the adjusting baffle 73 to move longitudinally along the working platform 1 until it presses against one end of the rocker arm in the length direction, so that the rocker arm is also firmly fixed in the longitudinal length direction at the predetermined position of the rubber strip on the working platform 1, which is directly opposite the through hole 9. Thus, by the adjustable limiting mechanism 7 pressing against one end of the rocker arm, and the specific structure of the two fixing brackets 8 engaging the sides of the rocker arm, the rectangular rocker arm is firmly restricted on the working platform 7, ensuring that it will not be displaced during the subsequent hydraulic extrusion process.
[0022] Rotate the hydraulic rod 5, whose outer thread engages with the adjusting nut 4 fixed in the middle of the support platform 3, and roughly adjust the distance between the bottom of the hydraulic rod 5 and the top surface of the rubber strip assembly to be removed on the rocker arm to a suitable range. Then, crank the hydraulic handle 6 to drive the hydraulic rod 5 downward, and its bottom passes through the through hole 9 to apply continuous squeezing force to the rubber strip assembly in the rocker arm, pressing the old rubber strip out of the rocker arm mounting groove.
[0023] After removing the old rubber strip, loosen the fixing bracket 8 and the adjustable limit mechanism 7, flip the rocker arm up and down so that the opening of the rubber strip mounting groove faces upward, reposition and firmly fix it on the work platform 1 according to the above steps, place the new rubber strip assembly between the bottom of the hydraulic rod 5 and the rocker arm rubber strip mounting groove; rotate the hydraulic rod 5 again to adjust its bottom height so that it leaves an appropriate distance from the top surface of the rubber strip assembly, and shake the hydraulic handle 6 to drive the hydraulic rod 5 to move downward, so that the new rubber strip assembly is smoothly and completely squeezed into the mounting groove of the rocker arm, completing the installation.
[0024] When it is necessary to disassemble or assemble bearing components: For bearings, bearing housings, or other box-like components that can be placed stably on the work platform 1, place the component to be disassembled in a suitable position on the work platform 1, and adjust the adjustable limit mechanism 7 and the mounting bracket 8 for auxiliary fixation according to the size of the component. Rotate the hydraulic rod 5 to adjust its height so that its bottom is close to or in contact with the point of action. Crank the hydraulic handle 6 to drive the hydraulic rod 5 to move downward and apply hydraulic pressure to achieve the disassembly or installation of components that are too tight or abnormally worn.
[0025] When the bearing or its parent component to be disassembled is irregularly shaped, too large, or inconvenient to place directly on the work platform 1, use the pull claw 11; loosen the adjusting bolt 12 at the top of the pull claw 11, slide the pull claw 11 in the grooves 10 at both ends of the support platform 3, adjust the distance between the two pull claws 11 so that the claws can firmly hook the inner ring, outer ring, or bearing housing of the bearing to be disassembled; tighten the adjusting bolt 12 to lock the position of the pull claw 11 in the groove 10; rotate the hydraulic rod 5 to adjust its height so that its bottom center presses against the shaft end that mates with the bearing or the component to be pressed in; crank the hydraulic handle 6 to drive the hydraulic rod 5 downward. While the hydraulic rod 5 presses down on the shaft end, it pulls the bearing upward through the pull claw 11, forming a strong pulling force to remove the overly tight-fitting bearing from the shaft. This mode essentially transforms the tooling into a hydraulically driven two-jaw puller.
[0026] When it is necessary to disassemble bearing components on large equipment or those that are inconvenient to move to the tooling location, the entire compaction and pulling mechanism can be detached from the work platform 1 and used as an independent handheld hydraulic two-jaw puller. The operating principle is the same as the puller mode described above, that is, adjust the position of the puller 11 and lock it to hook the bearing, the hydraulic rod 5 presses against the shaft end, and the handle 6 is cranked to pull and disassemble.
[0027] This utility model utilizes mechanical and hydraulic technology to enable the disassembly and replacement of the rubber strips on the rocker arms of vibrating conveyors and the disassembly of bearing components. It features a simple structure, convenient assembly and disassembly, and saves time and labor. The rocker arms and bearing components of vibrating conveyors used in cigarette manufacturing workshops are highly homogeneous and interchangeable, allowing for wide application. Furthermore, the replacement of the rubber strips significantly reduces the cost of rocker arm replacement and maintenance. Therefore, this utility model has considerable potential for widespread application.
[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
