Description

Technical Field

[0001] This utility model relates to the field of tobacco production equipment technology, and in particular to an auxiliary disassembly device. Background Technology

[0002] Currently, in the tobacco industry's production process, the filter rod forming machine is a key piece of equipment for ensuring filter rod quality and production efficiency. To ensure stable equipment performance and unobstructed airflow, the filter rod forming machine needs to be disassembled regularly to clean and maintain the airflow duct. Disassembling the flange is an essential and crucial step in this process.

[0003] However, the existing flange auxiliary disassembly device has an unreasonable snap-fit ​​structure design, making it difficult to accurately snap into the predetermined position during operation. This is not only time-consuming and laborious, but also prone to damage to the snap-fit ​​and flange due to repeated adjustments or forced operation, shortening the equipment's service life. At the same time, the device lacks an effective centering structure, making it impossible to accurately position the flange center during disassembly, resulting in unstable disassembly, which reduces efficiency and affects the accuracy of subsequent installation. In addition, the operation method poses safety hazards. Operators must hold the heavy flange with one hand to prevent it from falling while operating the tooling with the other hand. This is physically demanding and prone to errors due to fatigue. If the flange slips out of their hands, it will cause personal injury, equipment damage, or even production line shutdown, resulting in economic losses and production delays for the company. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary disassembly device to solve the problems of difficult clamping and positioning, poor centering effect, and major operational safety hazards during flange disassembly, thereby improving the disassembly efficiency, disassembly and assembly accuracy, and operational safety of flanges and receiving drums, and reducing equipment maintenance costs and labor intensity.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An auxiliary disassembly device is used to disassemble the flange connected to the receiving drum in a filter rod forming machine. The flange has an axially extending through-hole through which the axle of the receiving drum can pass. The outer side wall of the flange has a circumferentially circumferentially grooved groove. The auxiliary disassembly device includes:

[0007] The clamping assembly includes a bracket, a movable hook, and two fixed hooks. The two fixed hooks extend axially along the flange and are fixedly connected to the bracket. The movable hook is rotatably connected to the bracket. The two fixed hooks and the movable hook are distributed circumferentially along the flange. The inner sidewalls of the two fixed hooks and the movable hook are provided with hooks, and the hooks can engage with the slot.

[0008] A fixing bracket, connected to two fixing hooks, is provided to support the flange.

[0009] The jacking assembly has one end that can abut against the end face of the shaft of the receiving drum. The jacking assembly includes a lead screw, and the bracket has a threaded hole along the axial direction of the flange. The lead screw is screwed into the threaded hole so that the clamping assembly drives the flange to move axially.

[0010] As an optional solution for the auxiliary disassembly device, the bracket includes a disc-shaped part and three rod-shaped parts. The disc-shaped part has a wire hole at its center. The first ends of the three rod-shaped parts are arranged around the side wall of the disc-shaped part. The second end of one of the rod-shaped parts is rotatably connected to the movable hook body, and the second ends of the other two rod-shaped parts are respectively fixedly connected to the corresponding fixed hook body.

[0011] As an optional solution for the auxiliary disassembly device, the clamping assembly also includes a connecting shaft, wherein the second end of the rod-shaped part is provided with a first connecting hole, and the end of the movable hook is provided with a second connecting hole. The connecting shaft passes through the first connecting hole and the second connecting hole to allow the rod-shaped part and the movable hook to be rotatably connected.

[0012] As an optional auxiliary disassembly device, the fixing frame includes a support portion, which is U-shaped. The bottom of the U-shaped support portion is provided with an arc-shaped concave surface with the same diameter as the flange, and the side wall of the flange can abut against the arc-shaped concave surface.

[0013] As an optional solution for the auxiliary disassembly device, the auxiliary disassembly device also includes fasteners, and the clamping assembly also includes two connectors, which are respectively fixedly connected to the corresponding fixing hooks. The end of the connector away from the fixing hook is provided with a threaded hole, and the support part is provided with a mounting hole along the flange axis. The fastener passes through the mounting hole and is threadedly connected to the threaded hole.

[0014] As an optional auxiliary disassembly device, the side wall of the connector is provided with an anti-slip layer that can abut against the side wall of the flange.

[0015] As an optional auxiliary disassembly device, the mounting bracket also includes a handrail located on the top of the support and spaced apart from the flange, the handrail being configured for the operator to apply force by hand.

[0016] As an optional auxiliary disassembly device, the hand grip is provided with a handle cover, the outer surface of which is provided with friction texture.

[0017] As an optional auxiliary disassembly device, the jacking assembly also includes a jacking head connected to one end of the lead screw. The jacking head is tapered and has a ball bearing at its tip, which can roll against the end face of the receiving drum's axle.

[0018] As an optional auxiliary disassembly device, the jacking assembly also includes an operating panel, which is fixedly connected to the end of the lead screw away from the jacking head.

[0019] Beneficial effects:

[0020] This utility model provides an auxiliary disassembly device. During installation, the movable hook body first rotates to be perpendicular to the flange axis, allowing the two fixed hook bodies to engage with the flange's slots first. Then, the movable hook body is rotated to complete a three-point engagement. The three-point positioning principle ensures precise alignment between the auxiliary disassembly device and the flange, forming a stable engagement structure that avoids the problems of misalignment and damage common in traditional engagement methods. Subsequently, the push-off component abuts against the end face of the receiving drum's axle. Through the helical transmission of the screw and threaded hole, the turning force is converted into axial tension, driving the clamping component to move the flange smoothly along the axial direction, thus separating the flange from the receiving drum. This process eliminates the need for manual lifting of the flange, reducing the labor intensity of operators and eliminating safety hazards caused by human error. At the same time, the synergistic effect of the fixed frame and the clamping component ensures the stability and high precision of the disassembly process, significantly improving disassembly efficiency, extending equipment lifespan, and reducing enterprise equipment maintenance costs and production risks.

[0035] This embodiment provides an auxiliary disassembly device, such as... Figures 1-4As shown, the auxiliary disassembly device is used to disassemble the flange 100 connected to the receiving drum (not shown) in the filter rod forming machine. The flange 100 has a through hole 101 along the axial direction, through which the axle of the receiving drum can pass. The outer side wall of the flange 100 has a groove 102 circumferentially. The auxiliary disassembly device includes a clamping assembly 1, a fixing frame 2, and a lifting assembly 3. The clamping assembly 1 includes a bracket 11, a movable hook 12, and two fixed hooks 13. The two fixed hooks 13 extend along the axial direction of the flange 100 and are fixedly connected to the bracket 11. The movable hook 12 is rotatably connected to the bracket 11. Two fixed hooks 13 and a movable hook 12 are distributed circumferentially around the flange 100. The inner sidewalls of the two fixed hooks 13 and the movable hook 12 are provided with hooks 16, and the hooks 16 can be engaged with the slots 102. The fixed frame 2 is connected to the two fixed hooks 13 and can support the flange 100. One end of the lifting assembly 3 can abut against the end face of the receiving drum axle. The lifting assembly 3 includes a lead screw 31. The bracket 11 is provided with a threaded hole 111 along the axial direction of the flange 100. The lead screw 31 is screwed into the threaded hole 111 so that the clamping assembly 1 drives the flange 100 to move axially.

[0036] During installation, the movable hook 12 first rotates to be perpendicular to the axial direction of the flange 100, allowing the two fixed hooks 13 to engage with the slots 102 of the flange 100. Then, the movable hook 12 is rotated to complete the three-point engagement. The three-point positioning principle ensures precise alignment between the auxiliary disassembly device and the flange 100, forming a stable engagement structure that avoids the problems of misalignment and damage common in traditional engagements. Subsequently, the push-off assembly 3 abuts against the end face of the receiving drum's axle. Through the helical transmission of the lead screw 31 and the lead hole 111, the turning force is converted into axial tension, driving the clamping assembly 1 to move the flange 100 smoothly along the axial direction, thus separating the flange 100 from the receiving drum. This process eliminates the need for manual lifting of the flange 100, reducing the labor intensity of operators and eliminating safety hazards caused by human error. At the same time, the synergistic effect of the fixed frame 2 and the clamping assembly 1 ensures the stability and high precision of the disassembly process, significantly improving disassembly efficiency, extending equipment lifespan, and reducing enterprise equipment maintenance costs and production risks.

[0037] like Figure 1 and Figure 2As shown, the bracket 11 includes a disc-shaped part 112 and three rod-shaped parts 113. The center of the disc-shaped part 112 is provided with a wire hole 111. The first ends of the three rod-shaped parts 113 are arranged around the side wall of the disc-shaped part 112. The second end of one of the rod-shaped parts 113 is rotatably connected to the movable hook body 12, and the second ends of the other two rod-shaped parts 113 are respectively fixedly connected to the corresponding fixed hook bodies 13. The bracket 11 adopts a combination design of a disc-shaped part 112 and three rod-shaped parts 113. The central threaded hole 111 of the disc-shaped part 112 is screwed with the lead screw 31 to ensure that the axis is precisely coaxial when the force is applied to the top assembly 3, and to ensure that the flange 100 and the receiving drum are smoothly separated along the axis during disassembly. The three rod-shaped parts 113 are arranged in a ring, two of which are fixedly connected to the fixed hook body 13 and one is rotatably connected to the movable hook body 12, forming a stable triangular support structure. When snapping, the movable hook body 12 can adaptively adjust the angle to ensure a tight fit with the slot 102, while evenly distributing the disassembly force to prevent the bracket 11 from deforming and shaking. The overall structure is compact, simplifies the operation process, and effectively improves disassembly efficiency, stability and accuracy.

[0038] like Figure 1 and Figure 2 As shown, the clamping assembly 1 also includes a connecting shaft 14. A first connecting hole is provided at the second end of a rod-shaped portion 113, and a second connecting hole is provided at the end of the movable hook 12. The connecting shaft 14 passes through the first and second connecting holes to allow the rod-shaped portion 113 and the movable hook 12 to be rotatably connected. By connecting the first connecting hole of the rod-shaped portion 113 and the second connecting hole of the movable hook 12 through the connecting shaft 14, a stable hinge structure is formed, ensuring that the movable hook 12 can rotate flexibly around the connecting shaft 14 to achieve opening and closing actions with the fixed hook 13. This design allows operators to easily rotate the movable hook 12 to a suitable angle when installing the auxiliary disassembly device, first using the fixed hook 13 to initially engage the flange 100's slot 102, and then completing the three-point engagement by rotating the movable hook 12, simplifying the operation process and improving installation efficiency. Meanwhile, the rigid support of the connecting shaft 14 effectively restricts the radial displacement of the movable hook 12, preventing it from shaking or shifting during the clamping of the flange 100 or disassembly, ensuring the overall structure of the clamping assembly 1 is stable, and thus ensuring that the flange 100 and the receiving drum are subjected to uniform force and separated accurately during the disassembly process.

[0039] like Figure 2As shown, the end of the movable hook 12 is U-shaped, and the rod-shaped part 113 is located in the middle of the U-shaped end of the movable hook 12. The U-shaped end provides an embedded installation space for the rod-shaped part 113, which not only enhances the stability of the connection between the connecting shaft 14 and the first connecting hole and the second connecting hole by increasing the contact area, but also limits the radial swing of the movable hook 12 during rotation. At the same time, the rod-shaped part 113 is centrally located so that when the movable hook 12 rotates around the connecting shaft 14, the U-shaped ends on both sides exert symmetrical force on the rod-shaped part 113, avoiding the skew of the movable hook 12 due to eccentric force, ensuring the perpendicularity and accuracy of the hook 16 when it engages with the groove 102 of the flange 100, and further improving the ease of operation and structural reliability of the disassembly device.

[0040] like Figure 1 and Figure 4 As shown, the push assembly 3 also includes a push head 32, which is connected to one end of the lead screw 31. The push head 32 is a conical push head 32, and a ball 321 is provided at the tip of the conical push head 32. The ball 321 can roll and abut against the end face of the receiving drum. The conical pusher head 32's shape design allows the force to be concentrated and transmitted to the end face of the receiving drum's axle. The pointed structure effectively reduces the contact area and increases the pressure per unit area, ensuring that sufficient axial thrust can be generated with a small operating force when turning the screw 31, thus improving disassembly efficiency. The ball bearings 321 at the pointed end transform the traditional sliding contact into rolling friction, significantly reducing the friction between the pusher head 32 and the axle end face. This avoids wear and disassembly jamming of components (receiving drum axle, push-off assembly 3) due to excessive friction, while also making the pusher head 32 move more smoothly in the axial direction, reducing disassembly resistance. The rolling characteristics of the ball bearings 321 can also adaptively adjust the contact angle with the axle end face. Even if there are minor unevenness or assembly errors on the axle end face, it can ensure that the pusher head 32 always applies force stably in a point contact manner, preventing the flange 100 from shifting when separating from the receiving drum due to eccentric load, thus ensuring the accuracy and stability of the disassembly process.

[0041] like Figure 1 and Figure 4 As shown, the top-removal assembly 3 also includes an operating disc 33, which is fixedly connected to the end of the lead screw 31 furthest from the push head 32. The operating disc 33, by increasing the force application area, evenly distributes the hand force to the lead screw 31, avoiding hand fatigue and slippage risks caused by concentrated force when directly turning the lead screw 31. The disc-shaped structure provides ample gripping space, allowing operators to apply force with one or both hands, flexibly adjusting the direction and intensity of force according to the disassembly resistance, effectively improving the controllability of the disassembly operation. Figure 4 As shown, the operating disc 33 is shaped like a plum blossom. When turning it, simply hold the side wall of the operating disc 33 firmly.

[0042] like Figures 1-3As shown, the fixing frame 2 includes a support part 21, which is U-shaped. The bottom of the U-shaped support part has an arc-shaped concave surface with the same diameter as the flange 100, and the side wall of the flange 100 can abut against the arc-shaped concave surface. The U-shaped support part provides an open containment space for the flange 100, which facilitates the quick insertion and removal of the flange 100. At the same time, the two arms of the U-shaped support part can provide lateral restraint for the flange 100, preventing the flange 100 from shifting laterally during disassembly. The bottom arc-shaped concave surface is precisely matched with the diameter of the flange 100, which increases the support area through surface contact, so that the side wall of the flange 100 is evenly stressed, effectively dispersing the axial thrust generated by the push assembly 3 during disassembly, and avoiding deformation or damage caused by local stress concentration of the flange 100. This fitting design also plays a role in precise positioning, ensuring that the center of the flange 100 is coaxial with the axis of the lead screw 31, providing a stable force base when the push head 32 abuts against the end face of the wheel axle, and ensuring that the disassembly process is smooth and without shaking.

[0043] In other embodiments, the bottom of the support 21 is flat, and the outer wall of the flange 100 and the support 21 are in contact at three points. Based on the principle that three points determine a plane, the three contact points can precisely define the radial position of the flange 100. Even if there is a slight difference in the outer diameter of the flange 100, the contact angle can be adjusted adaptively by the three points to ensure that the flange 100 remains stable during disassembly and avoids shaking or eccentricity caused by the mismatch between the bottom arc surface and the flange 100 size. The structure of the flat bottom simplifies the processing technology of the fixing frame 2 and reduces the manufacturing cost.

[0044] like Figures 1-3 As shown, the auxiliary disassembly device also includes a fastener 4, and the clamping assembly 1 also includes two connectors 15. The two connectors 15 are respectively fixedly connected to the corresponding fixing hooks 13. The end of the connector 15 away from the fixing hooks 13 is provided with a threaded hole 151. The support part 21 is provided with an installation hole 211 along the axial direction of the flange 100. The fastener 4 passes through the installation hole 211 and is threadedly connected to the threaded hole 151. Two connectors 15 are fixedly connected to the fixed hook body 13, effectively transmitting the installation force of the fastener 4 to the fixed hook body 13, preventing the fixed frame 2 and clamping assembly 1 from separating due to force during disassembly. The threaded hole 151 at one end of the connector 15 precisely corresponds to the mounting hole 211 of the support part 21. By tightening the thread of the fastener 4, a high-strength axial preload can be formed, ensuring that the fixed hook body 13 remains stable when subjected to the axial thrust of the lifting assembly 3, preventing the flange 100 from shaking or shifting during disassembly. This threaded connection method facilitates the assembly and disassembly of the auxiliary disassembly device. Only by loosening the fastener 4 can the clamping assembly 1 and the fixed frame 2 be quickly separated, significantly improving equipment maintenance efficiency. In this embodiment, the fastener 4 is selected as a bolt or screw.

[0045] In this embodiment, the sidewall of the connector 15 is provided with an anti-slip layer (not shown), which can abut against the sidewall of the flange 100. The anti-slip layer abuts tightly against the sidewall of the flange 100. By increasing the surface roughness or using a high coefficient of friction material (such as rubber or textured coating), the static friction between the connector 15 and the flange 100 is significantly improved, preventing the flange 100 from sliding relative to the connector 15 due to the force applied by the push-off assembly 3 during disassembly, and ensuring the stable clamping of the flange 100 by the clamping assembly 1.

[0046] like Figure 1 and Figure 3 As shown, the mounting bracket 2 also includes a handrail 22, which is located on top of the support 21 and spaced apart from the flange 100. The handrail 22 is configured for the operator to hold and apply force. The handrail 22 provides a gripping point for the operator. By holding the handrail 22 and applying force, the operator can flexibly adjust the posture of the mounting bracket 2, assisting the flange 100 in quick positioning and engagement with the clamping assembly 1. At the same time, when working on the lifting assembly 3, the handrail 22 can apply a reverse stabilizing force to counteract the reaction force generated by the screw 31 turning, preventing the mounting bracket 2 from shifting or tipping due to uneven force, and ensuring a smooth and controllable disassembly process.

[0047] like Figure 1 and Figure 3 As shown, the handgrip 22 is provided with a grip sleeve 23, and the outer surface of the grip sleeve 23 is provided with friction texture (not shown). The friction texture on the outer surface of the grip sleeve increases the contact area and surface roughness, effectively enhancing the friction between the hand and the grip sleeve 23, avoiding the risk of the fixing frame 2 shaking or even the flange 100 falling due to slippage during disassembly; the grip sleeve 23 is usually made of elastic cushioning material, such as rubber, which can absorb the vibration generated by the screw 31 during disassembly, further improving the grip comfort.

[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.
