Description

Technical Field

[0001] This utility model relates to the field of roller conveyor rubber ring replacement technology, and more specifically, it relates to a roller conveyor rubber ring replacement device. Background Technology

[0002] In current industrial production processes, roller conveyor rubber rings are key consumable components in the transmission system. Their replacement and maintenance directly affect the operating efficiency and product quality of the production line. However, existing roller conveyor rubber ring replacement devices have technical defects and operational difficulties that urgently need to be addressed in practical applications.

[0003] Firstly, the traditional method of replacing roller conveyor rubber rings still largely relies on manual operation. In this method, maintenance personnel must first use clamps or other fixing devices to firmly hold and fix the roller conveyor, ensuring that it does not slip or rotate during the replacement process. Then, the workers need to manually peel off and remove the old and worn rubber rings from the roller conveyor surface, and then apply considerable external force to push, stretch, and fit the new rubber rings little by little along the roller conveyor surface. This replacement method, which relies entirely on manual labor, not only consumes a lot of physical strength and time, but also, due to the uneven application of manual force, it is easy for the rubber rings to be subjected to uneven stress during installation, resulting in minor damage or deformation, which in turn affects their service life and working performance. On large production lines, there may be dozens or even hundreds of roller conveyors that require regular replacement of rubber rings. This inefficient manual replacement method significantly prolongs equipment maintenance time, increases downtime losses, and also increases the labor intensity of maintenance personnel, resulting in a serious waste of human resources and unnecessary occupational health risks.

[0004] Secondly, in response to the aforementioned pain points of manual operation, some manufacturers in the industry have indeed developed mechanized roller conveyor rubber ring replacement equipment. Through the combined use of a moving sleeve and a pushing sleeve, semi-automatic replacement of the rubber ring can be achieved. These devices are generally designed with a moving sleeve that is compatible with the roller conveyor, and the outer side of the moving sleeve works with the pushing sleeve to form a rubber ring installation mechanism. However, these devices show obvious lack of versatility when dealing with roller conveyors of different diameters and specifications. Due to the diversity of roller conveyor diameters and the differentiated requirements of different production lines for roller conveyor structure design, it is usually necessary to remove and replace the moving sleeve and the pushing sleeve for each change of roller conveyor rubber ring specification. More importantly, the installation and removal of these moving sleeves and pushing sleeves often involve complex bolt connections and other traditional connection methods, requiring the use of multiple professional tools such as wrenches, hydraulic disassembly tools, etc. This complex tool dependence and cumbersome disassembly and assembly process significantly prolongs the equipment adjustment time, seriously reduces the flexibility and adaptability of the equipment, and brings additional time costs and management burdens to enterprises.

[0005] Furthermore, in response to the aforementioned inconvenience in replacing the movable sleeve and the push sleeve, some advanced companies have indeed attempted to facilitate the replacement of the movable sleeve and the push sleeve by designing quick-connect devices. However, these quick-connect devices often lack stability, especially in operating environments with long-term equipment operation or frequent external vibrations. These simple quick-connect devices are prone to malfunctions such as insecure locking or even accidental unlocking. Specifically, when the equipment is subjected to external impacts or vibrations during operation, these simple locking mechanisms may gradually loosen. This can not only cause the movable sleeve and the push sleeve to shift, become eccentric, or rotate during operation, affecting the accuracy and consistency of the rubber ring installation, but more seriously, it may cause the movable sleeve and the push sleeve to completely fall off, not only interrupting the rubber ring replacement operation, but also potentially causing safety accidents such as equipment damage or personal injury.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a roller conveyor rubber ring replacement device, which has the following features:

[0019] Beneficial effects:

[0020] 1. The replacement device consists of a first cylinder, a first piston rod, a second cylinder, a sliding frame, a moving sleeve, a pushing sleeve, a mounting frame, a second piston rod, and a variable diameter sleeve. It enables efficient semi-automatic replacement of roller conveyor rubber rings. Compared to the traditional manual operation mode, this device uses a piston rod driven by a cylinder to drive the sliding frame and the moving sleeve to move smoothly. The moving sleeve, in conjunction with the variable diameter sleeve, applies a uniform force to the rubber ring on the outside of the roller conveyor, smoothly lifting it and fitting it onto the outside of the moving sleeve. Subsequently, the moving sleeve detaches from the outside of the roller conveyor, taking the old rubber ring out with it. Through precisely controlled cylinder piston movement, the pushing sleeve can evenly remove the old rubber ring from the outside of the moving sleeve. Then, by reversing the above steps, the installation of the new rubber ring can be completed. This significantly reduces manpower input and operation time, while ensuring that the rubber ring is subjected to uniform force during installation, avoiding minor damage or deformation, greatly improving equipment maintenance efficiency, reducing downtime losses, and alleviating the labor intensity of maintenance personnel.

[0021] 2. The locking device consists of a locking rod, a locking sleeve, a control sleeve, a locking groove, a control plate, and a locking frame. This device solves the problem of cumbersome installation and removal operations for the moving sleeve and the pushing sleeve in existing technologies. The locking sleeve is detachably fitted onto the outside of the locking rod, and the control sleeve is rotatably installed on the outside of the locking sleeve. With the locking groove and the locking frame engaging, the moving sleeve and the pushing sleeve can be quickly installed and removed without the need for wrenches, hydraulic tools, or other specialized tools. This simplifies tool dependence and the installation and removal process, enabling convenient replacement of the moving sleeve and the pushing sleeve. It significantly improves the equipment's adaptability to roller conveyors of different diameters and specifications, enhances the equipment's flexibility and adaptability, and saves enterprises time, costs, and management burden.

[0022] 3. The limiting mechanism consists of components such as a linkage rod, linkage plate, movable spring, movable block, linkage hole, shift sleeve, shift frame, shift groove, fixing block, shift rod, and shift plate. Combined with auxiliary components such as the linkage spring, movable rod, movable hole, guide groove, guide block, connecting spring, and shift spring, it effectively solves the problem of insufficient stability in existing quick-connect devices. This mechanism ensures the stability of the locking device during operation through multiple locking mechanisms. In particular, the linkage rod, linkage hole, and shift sleeve together form the first locking mechanism, and the shift rod and shift groove together form the second locking mechanism. This multi-locking mechanism effectively prevents malfunctions such as insecure locking or accidental unlocking that may occur during long-term operation or in environments with frequent external vibrations. It avoids the risk of displacement, eccentricity, or rotation of the moving sleeve and pushing sleeve during operation, and also eliminates the hidden danger of the moving sleeve and pushing sleeve completely falling off, leading to interruption of rubber ring replacement operations or safety accidents. It ensures the accuracy and consistency of rubber ring installation, guaranteeing the working stability and safety reliability of the equipment during long-term use. Attached Figure Description

A limiting mechanism is installed on the outside of the locking sleeve 3. The limiting mechanism includes a linkage rod 9, a linkage plate 10, a movable spring 11, and a movable spring 12. The system includes a block 12, a linkage hole 13, a shift sleeve 14, a shift frame 15, a shift groove 16, a fixing block 17, a shift rod 18, and a shift plate 19. The linkage rod 9 is fixedly installed on one side of the shift sleeve 14. The two ends of the movable spring 11 are respectively connected to the movable block 12 and the fixing block 17. The linkage plate 10 is rotatably installed on the outside of the locking sleeve 3. The movable block 12 is fixedly installed on one side of the linkage plate 10. The linkage hole 13 is opened on the linkage plate 10. The shift sleeve 14 is slidably installed on the outside of the locking sleeve 3. The shift frame 15 is fixedly installed on one side of the control sleeve 4. The shift groove 16 is opened on the outside of the locking sleeve 3. The fixing block 17 is fixedly installed on one side of the control sleeve 4. The shift rod 18 is slidably installed in the shift frame 15. The shift plate 19 is fixedly connected to one end of the shift rod 18.

[0033] The replacement device includes a first cylinder 20, a first piston rod 21, a second cylinder 22, a sliding frame 23, a movable sleeve 24, a push sleeve 25, a mounting frame 26, a second piston rod 27, and a variable diameter sleeve 28. The first cylinder 20 is detachably installed above the top plate 1. The top end of the first piston rod 21 is connected to the output end of the first cylinder 20, and the bottom end of the first piston rod 21 is detachably connected to the top end of the sliding frame 23. The second cylinder 22 is detachably installed inside the sliding frame 23, which is located below the top plate 1. The movable sleeve 24 is detachably installed below the second piston rod 27. The push sleeve 25 is slidably mounted on the outside of the movable sleeve 24 and is fixedly installed below the mounting frame 26. The mounting frame 26 is detachably installed below the sliding frame 23. The top end of the second piston rod 27 is connected to the output end of the second cylinder 22, and the variable diameter sleeve 28 is fixedly installed at the bottom end of the push sleeve 25.

[0034] A guide sleeve 29 is detachably provided on the sliding frame 23, and a guide rod 30 is detachably provided below the top plate 1. The sliding frame 23 and the guide sleeve 29 are slidably connected to the guide rod 30, and a base plate 31 is fixedly connected to the bottom end of the guide rod 30.

[0035] In this embodiment, when the device is needed to replace the rubber ring, the roller conveyor is first clamped and fixed above the base plate 31 by the external clamping device, ensuring that the roller conveyor is concentric with the movable sleeve 24. Then, the second cylinder 22 is opened, causing the second cylinder 22 to drive the movable sleeve 24 to descend via the second piston rod 27 connected to the output end. This causes the movable sleeve 24 to drive the variable diameter sleeve 28 to extend from the push sleeve 25. When the second piston rod 27 drives the variable diameter sleeve 28 and the movable sleeve 24 to descend to the bottom, the second cylinder is closed. 22. Then, the first cylinder 20 is opened, driving the first piston rod 21 connected to the output end to move. The first piston rod 21 then drives the sliding frame 23 to descend. The sliding frame 23 then drives the guide sleeve 29 to slide downwards along the guide rod 30. The sliding frame 23 also drives the second cylinder 22 and the mounting frame 26, among other components, to descend together. This causes the push sleeve 25, the variable diameter sleeve 28, and the moving sleeve 24 to descend synchronously. Then, the inner wall of the variable diameter sleeve 28 contacts the outer wall of the roller conveyor and gradually lifts the outer rubber ring. The movable sleeve 24 gradually and completely engages with the outside of the roller conveyor, causing the rubber ring to be lifted and engaged with the outside of the movable sleeve 24. Then, the first cylinder 20 is driven in reverse, causing the first piston rod 21 at the output end of the first cylinder 20 to drive the sliding frame 23 and other components to rise synchronously, causing the movable sleeve 24 to disengage from the outside of the roller conveyor and take the rubber ring out. After the sliding frame 23 rises to its highest point, the first cylinder 20 is closed, and the second cylinder 22 is driven in reverse. The second cylinder 22 drives the movable sleeve 24 through the second piston rod 27. 4. The roller rises, and then, because the inner wall of the push sleeve 25 is in contact with the outer wall of the moving sleeve 24, the push sleeve 25 will gradually remove the rubber ring on the outer side of the moving sleeve 24, thereby removing the rubber ring. Then the moving sleeve 24 is pushed out again, and a new rubber ring is fitted onto the outer side of the moving sleeve 24. Then the above steps are reversed, and finally the moving sleeve 24 is fitted onto the outer side of the roller table again. Then the moving sleeve 24 drives the variable diameter sleeve 28 to rise, while the push sleeve 25 remains stationary, thus realizing the replacement of the rubber ring.

[0036] Please see Figures 3-5 As a further implementation of the overall equipment: a linkage spring 32 is movably sleeved on the outside of the linkage rod 9. One end of the linkage spring 32 is connected to the displacement sleeve 14, and the other end of the linkage spring 32 is connected to the linkage plate 10 in contact.

[0037] A movable rod 33 is connected to one side of the movable block 12, and a movable hole 34 is opened in the fixed block 17. One end of the movable rod 33 slides into the movable hole 34.

[0038] The outer side of the retaining sleeve 3 is provided with a guide groove 35, and a guide block 36 is slidably provided in the guide groove 35. The guide block 36 is fixedly installed on the inner wall of the displacement sleeve 14.

[0039] A connecting spring 37 is fitted on the outer side of the clamping frame 8, and the two ends of the connecting spring 37 are connected to the control plate 6 and the outer wall of the clamping sleeve 3, respectively.

[0040] A shift spring 38 is movably sleeved on the outside of the shift rod 18, and the two ends of the shift spring 38 are connected to the shift plate 19 and the shift frame 15 respectively.

[0041] More specifically, when it is necessary to replace the movable sleeve 24 and the pushing sleeve 25, firstly, rotate the linkage plate 10 in the forward direction, so that the linkage plate 10 drives the linkage hole 13 to rotate in the forward direction. Then, the linkage plate 10 will drive the linkage hole 13 to rotate, and at the same time, the linkage plate 10 will drive the movable block 12 on one side to rotate in the forward direction. Then, the movable block 12 will drive the movable rod 33 to rotate in the forward direction along the movable hole 34. The movable block 12 and the fixed block 17 cooperate to compress the movable spring 11. When the movable spring 11 is compressed to its limit, the linkage hole 13 just rotates to a position concentric with the linkage rod 9. Then, push the shift sleeve 14. The shift sleeve 14 will drive the linkage rod 9 on one side to slide, so that the linkage rod 9 passes into the linkage hole 13. The shift sleeve 14 will cooperate with the linkage plate 10 to connect. The spring 32 compresses, and then the inner wall of the shift sleeve 14 no longer limits the outer wall of the shift plate 19. Then, the control sleeve 4 rotates in the forward direction, which drives one side of the shift frame 15 to rotate in the forward direction. Then, the shift frame 15 drives the shift rod 18 and other components to rotate. Then, the inner wall of the shift groove 16 compresses one end of the shift rod 18. Due to the rounded corner design at the edge of the inner wall of the shift groove 16 and one end of the shift rod 18, one end of the shift rod 18 will slide out of the shift groove 16, and the other end of the shift rod 18 will be stretched by the shift spring 38 through the shift plate 19. At the same time, the control sleeve 4 will drive the control groove 7 opened in the inner diameter-changing structure to rotate in the forward direction. Then, the connecting spring 37 will gradually return to its original position and push the control plate 6 outward, so that the outer wall of the control plate 6 is always in contact with the inner wall of the control groove 7. The control panel 6 is aligned, causing one side of the retaining bracket 8 to gradually detach from the retaining groove 5. Then, the retaining sleeve 3 is pulled downwards to remove it. The other retaining sleeves 3 are removed following the same steps. The mounting bracket 26, along with the push sleeve 25, can then be removed. The movable sleeve 24 can then be removed, and the movable sleeve 24 and mounting bracket 26 can be replaced. After replacement, both are placed in their corresponding positions, and the retaining rod 2 passes through the pre-drilled mounting hole. The retaining sleeve 3 is then re-fitted onto the outside of the retaining rod 2. The control sleeve 4 is then rotated in the opposite direction, causing one side of the shifting bracket 15 to rotate in the opposite direction, which in turn causes the shifting rod 18 and other components to rotate in the opposite direction. Simultaneously, the control sleeve 4 will... The inner control groove 7 rotates in the opposite direction, and then the inner wall of the control groove 7 gradually presses against the control plate 6, causing the control plate 6 to gradually slide inward. This allows the inner wall of the control plate 6 and the outer wall of the locking sleeve 3 to press against the connecting spring 37. At the same time, the control plate 6 will drive one side of the locking bracket 8 to gradually re-lock into the locking groove 5. At this time, the shift bracket 15 just drives the shift rod 18 to move to the position corresponding to the original shift groove 16. Then, the shift spring 38 pulls the shift plate 19 to slide inward, causing the shift plate 19 to drive the shift rod 18 to slide back to its original position, and causing one end of the shift rod 18 to re-insert into the original shift groove 16. Then, the shift sleeve 14 is released, and the linkage spring 32 pushes the shift sleeve 14 to slide back to its original position. Then, the shift sleeve 14 will drive the inner guide block 36 to slide back to its original position along the guide groove 35.Furthermore, the shift sleeve 14 will cause the linkage rod 9 to slide and reset. After the linkage spring 32 is fully reset, the linkage rod 9 will no longer limit the linkage plate 10 through the linkage hole 13. Then, the movable spring 11 will push the movable block 12 to rotate and reset. Then, the movable block 12 will drive the movable rod 33 on one side to rotate and reset along the movable hole 34. The movable block 12 will also drive the linkage hole 13 to rotate and reset to a position that does not correspond to the linkage rod 9 through the linkage plate 10. At this time, the linkage rod 9 will support the shift sleeve 14 to one side of the movable plate, cooperating with the guide block 36 and the guide groove. The 35th pinion limits the movement of the shift sleeve 14, preventing it from moving. The inner wall of the shift sleeve 14 then limits the outer side of the shift plate 19, preventing the shift plate 19 and shift rod 18 from moving outwards. This allows the shift rod 18 and shift groove 16 to cooperate in limiting and fixing the locking frame. The locking frame then limits the rotation of the control sleeve 4, preventing it from rotating and thus avoiding accidental unlocking. This ensures the stable installation of the shift sleeve 24 and the push sleeve 25, and guarantees the stable operation of the rubber ring replacement.

[0042] In summary, when using or operating the entire equipment: First, when replacing the rubber ring, the roller conveyor is clamped and fixed above the base plate 31 using the external clamping device, ensuring the roller conveyor is concentric with the moving sleeve 24. Then, the second cylinder 22 is activated, causing it to drive the moving sleeve 24 downwards via the second piston rod 27 connected to its output end. This causes the moving sleeve 24 to pull the variable diameter sleeve 28 out of the push sleeve 25. When the second piston rod 27 pulls the variable diameter sleeve 28 and the moving sleeve 24 to their lowest point… The second cylinder 22 is closed, and the first cylinder 20 is opened. The first cylinder 20 drives the first piston rod 21 connected to the output end to move. Then, the first piston rod 21 drives the sliding frame 23 to descend. The sliding frame 23 then drives the guide sleeve 29 to slide downward along the guide rod 30. The sliding frame 23 also drives the second cylinder 22 and the mounting frame 26 to descend together, causing the push sleeve 25, the variable diameter sleeve 28, and the moving sleeve 24 to descend synchronously. Then, the inner wall of the variable diameter sleeve 28 comes into contact with the outer wall of the roller conveyor and gradually pushes the outer rubber ring. The first cylinder 20 is then driven in reverse, causing the sliding frame 23 and other components to rise synchronously via the first piston rod 21 at the output end. This causes the sliding sleeve 24 to disengage from the outside of the roller conveyor, carrying the rubber ring with it. After the sliding frame 23 reaches its highest point, the first cylinder 20 is deactivated. Then, the second cylinder 22 is driven in reverse, and the second cylinder 22 drives the sliding frame 23 via the second piston rod 27. The sleeve 24 rises, and then, because the inner wall of the push sleeve 25 is in contact with the outer wall of the movable sleeve 24, the push sleeve 25 will gradually remove the rubber ring on the outer side of the movable sleeve 24, thereby removing the rubber ring. Then the movable sleeve 24 is pushed out again, and a new rubber ring is fitted onto the outer side of the movable sleeve 24. Then the above steps are reversed, and finally the movable sleeve 24 is fitted onto the outer side of the roller table again. Then the movable sleeve 24 drives the variable diameter sleeve 28 to rise, while the push sleeve 25 remains stationary, thus realizing the replacement of the rubber ring.

[0043] When it is necessary to replace the movable sleeve 24 and the pushing sleeve 25, first rotate the linkage plate 10 clockwise, so that the linkage plate 10 drives the linkage hole 13 to rotate clockwise. Then, the linkage plate 10 will drive the linkage hole 13 to rotate, and at the same time, the linkage plate 10 will drive the movable block 12 on one side to rotate clockwise. Then, the movable block 12 will drive the movable rod 33 to rotate clockwise along the movable hole 34. The movable block 12 and the fixed block 17 cooperate to compress the movable spring 11. When the movable spring 11 is compressed to its limit, the linkage hole 13 just rotates to a position concentric with the linkage rod 9. Then push the shift sleeve 14. The shift sleeve 14 will drive the linkage rod 9 on one side to slide, so that the linkage rod 9 passes into the linkage hole 13. The shift sleeve 14 will cooperate with the linkage plate 10 to compress the linkage spring 32. The compression causes the inner wall of the shift sleeve 14 to no longer limit the outer wall of the shift plate 19. Then, the control sleeve 4 rotates forward, causing one side of the shift frame 15 to rotate forward. The shift frame 15 then rotates the shift rod 18 and other components. The inner wall of the shift groove 16 then compresses one end of the shift rod 18. Due to the rounded corners at the edge of the inner wall of the shift groove 16 and one end of the shift rod 18, one end of the shift rod 18 slides out of the shift groove 16, and the other end of the shift rod 18 is stretched by the shift spring 38 via the shift plate 19. Simultaneously, the control sleeve 4 causes the control groove 7, which is formed by an inner variable diameter structure, to rotate forward. Then, the connecting spring 37 gradually resets and pushes the control plate 6 outward, ensuring that the outer wall of the control plate 6 remains in contact with the inner wall of the control groove 7. This causes the control panel 6 to gradually disengage the locking bracket 8 from the locking groove 5. Then, the locking sleeve 3 is pulled downwards to remove it. The other locking sleeves 3 are removed following the same steps. The mounting bracket 26, along with the push sleeve 25, can then be removed. The movable sleeve 24 can then be removed, and the movable sleeve 24 and mounting bracket 26 can be replaced. After replacement, both are placed in their corresponding positions, and the locking rod 2 passes through the pre-drilled mounting hole. The locking sleeve 3 is then re-fitted onto the outside of the locking rod 2. The control sleeve 4 is then rotated in the opposite direction, causing the control sleeve 4 to drive the shifting bracket 15 to rotate in the opposite direction. This causes the shifting bracket 15 to drive the shifting rod 18 and other components to rotate in the opposite direction. Simultaneously, the control sleeve 4 will drive the inner... The side control groove 7 rotates in the opposite direction, and then the inner wall of the control groove 7 gradually presses against the control plate 6, causing the control plate 6 to gradually slide inward. This allows the inner wall of the control plate 6 and the outer wall of the locking sleeve 3 to press against the connecting spring 37. At the same time, the control plate 6 will drive the one-sided locking bracket 8 to gradually re-lock into the locking groove 5. At this time, the shift bracket 15 just drives the shift rod 18 to move to the position corresponding to the original shift groove 16. Then, the shift spring 38 pulls the shift plate 19 to slide inward, causing the shift plate 19 to drive the shift rod 18 to slide back to its original position, and causing one end of the shift rod 18 to re-insert into the original shift groove 16. Then, the shift sleeve 14 is released, and the linkage spring 32 pushes the shift sleeve 14 to slide back to its original position. Then, the shift sleeve 14 will drive the inner guide block 36 to slide back to its original position along the guide groove 35.Furthermore, the shift sleeve 14 will cause the linkage rod 9 to slide and reset. After the linkage spring 32 is fully reset, the linkage rod 9 will no longer limit the linkage plate 10 through the linkage hole 13. Then, the movable spring 11 will push the movable block 12 to rotate and reset. Then, the movable block 12 will drive the movable rod 33 on one side to rotate and reset along the movable hole 34. The movable block 12 will also drive the linkage hole 13 to rotate and reset to a position that does not correspond to the linkage rod 9 through the linkage plate 10. At this time, the linkage rod 9 will support the shift sleeve 14 to one side of the movable plate, cooperating with the guide block 36 and the guide groove. The 35th pinion limits the movement of the shift sleeve 14, preventing it from moving. The inner wall of the shift sleeve 14 then limits the outer side of the shift plate 19, preventing the shift plate 19 and shift rod 18 from moving outwards. This allows the shift rod 18 and shift groove 16 to cooperate in limiting and fixing the locking frame. The locking frame then limits the rotation of the control sleeve 4, preventing it from rotating and thus avoiding accidental unlocking. This ensures the stable installation of the shift sleeve 24 and the push sleeve 25, and guarantees the stable operation of the rubber ring replacement.
