Technical Field
[0001] This utility model relates to the field of redirection roller technology, specifically a redirection roller that is not easily deformed. Background Technology
[0002] A redirecting roller, also known as a guide roller, is a common key component of belt conveyors. It is mainly used to change the running direction of the conveyor belt or to tighten the conveyor belt to increase its wrap angle with the drive roller. Redirecting rollers are suitable for conveying machinery, primarily used in metallurgy, mining, ports, chemical and pharmaceutical industries, cement and building materials, steel, and coal mining, and serve as the drive unit for various belt conveyors.
[0003] Existing redirecting rollers are generally hollow, which causes them to deform over time when conveying heavier items, thus affecting their performance. If a solid structure is used, the weight of the redirecting roller will increase dramatically, which is unnecessary when conveying lighter items. Heavy redirecting rollers also increase energy consumption and are not practical.
[0004] Therefore, a non-deformable redirecting roller that can be adjusted and reinforced according to the conveyed items is needed. Utility Model Content
[0005] To address the aforementioned issues, this invention proposes a non-deformable redirecting roller. The roller body is reinforced with detachable reinforcing components to prevent deformation. The reinforcing components can be disassembled and assembled according to the weight of the transported items, making it more flexible and practical.
[0006] To achieve the above objectives, the present invention proposes the following specific solutions:
[0007] A non-deformable redirecting roller includes a roller body. A fixed disc is fixed to the inner wall of the roller body. Rotating shafts are symmetrically fixed to the side walls of the fixed disc. A receiving groove is provided on the inner side of the rotating shaft. A movable groove is provided on the side edge of the inner wall of one side of the receiving groove. A connecting hole is provided on the side of the movable groove on one side of the receiving groove. A support plate is provided on the inner side of the receiving groove. A pressing block is fixed to the side edge of one side of the support plate. The pressing block passes through the movable groove. A limiting rod is fixed to one side of the support plate. The limiting rod is located on the side of the pressing block and passes through the connecting hole. A first spring is fixed to the other side wall of the support plate. One end of the first spring is fixed to the inner wall of the receiving groove. A reinforcing assembly is movably sleeved on the outer side of the rotating shaft. The reinforcing assembly includes an mounting ring and a reinforcing ring. The mounting ring is movably sleeved on the outer side of the rotating shaft. A limiting groove is provided on the inner wall of the mounting ring. One end of the limiting rod is movably inserted into the inner side of the limiting groove. A reinforcing plate is fixed to the outer wall of the mounting ring. A reinforcing ring is fixed to one end of the reinforcing plate.
[0008] As a preferred technical solution for a reversing roller that is not easily deformed according to this utility model, a rectangular groove is provided on the inner wall of the other side of the receiving groove, and a toggle groove is provided on the inner wall of one side of the rectangular groove.
[0009] As a preferred technical solution for a reversing roller that is not easily deformed according to this utility model, a plug-in plate is movably inserted into the inner side of the rectangular groove, and the plug-in plate is located on one side of the support plate.
[0010] As a preferred technical solution for a reversing roller that is not easily deformed according to this utility model, a second spring is fixed at one end of the plug plate, and the second spring is fixed at one end to the inner wall of the rectangular groove.
[0011] As a preferred technical solution for a reversing roller that is not easily deformed according to this utility model, a toggle block is fixed on one side wall of the plug plate, and the toggle block is located inside the toggle groove.
[0012] As a preferred technical solution for a reversing roller that is not easily deformed according to this utility model, one end of the support plate is provided with an insertion groove, the size of which is adapted to the size of the insertion plate.
[0013] As a preferred technical solution for a reversing roller that is not easily deformed according to this utility model, the inner wall of the mounting ring is provided with a notch, and a fixing strip is fixed to the outer wall of the rotating shaft, with the fixing strip penetrating the notch.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] The reinforcing component of this invention is located inside the roller body, supporting and reinforcing the roller body to prevent deformation. The reinforcing component is installed on the outside of the rotating shaft via an mounting ring. Under the support of a first spring, the limiting rod on the side wall of the support plate is inserted into the limiting groove on the inner wall of the mounting ring to fix the mounting ring. By pressing the pressing block, the support plate can be driven to compress the first spring, thereby causing the limiting rod to disengage from the limiting groove, and the mounting ring can be removed. The reinforcing component of this solution can be easily assembled and disassembled. When the roller body is conveying heavier items, the reinforcing component reinforces the roller body to prevent deformation. When the roller body is conveying lighter items, the reinforcing component can be removed to reduce the weight of the roller body, reduce energy consumption, and improve flexibility and practicality.
[0016] In this invention, after the reinforcing component is installed inside the drum body, the mounting ring is fixed to the outside of the rotating shaft, and the limiting rod is inserted into the limiting groove, the plug plate can move to one side of the support plate under the pushing action of the second spring, preventing the support plate from moving. This ensures that the support plate will not accidentally drive the limiting rod to move during drum body operation, thus preventing instability of the reinforcing component and enhancing safety. When disassembling the reinforcing component, a tool (such as a flathead screwdriver) is used to move the lever, causing the lever to move the plug plate to compress the second spring, which allows the plug plate to retract completely into the rectangular groove. At this time, pressing the pressing block will move the support plate. After the support plate drives the limiting rod out of the limiting groove, the plug plate can be inserted into the plug groove at one end of the support plate under the pushing action of the second spring, again restricting the movement of the support plate and preventing the limiting rod from entering the limiting groove, making it convenient to disassemble the mounting ring.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example
[0026] Please see Figure 1-6 As shown, the present invention provides the following technical solution: a non-deformable redirecting roller, including a roller body 1, a fixing plate 11 fixed on the inner wall of the roller body 1, and a rotating shaft 12 symmetrically fixed on the side wall of the fixing plate 11. The fixing plate 11 can support the roller body 1 and fix the rotating shaft 12. The rotating shaft 12 is connected to a bearing and drives the roller body 1 to rotate to transport items.
[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, specifically, the inner side of the rotating shaft 12 is provided with a receiving groove 121 for accommodating the moving support plate 13. A movable groove 123 is provided on one side of the inner wall of the receiving groove 121 for the moving of the pressing block 134. A connecting hole 122 is provided on one side of the inner wall of the receiving groove 121 for the limiting rod 132 to pass through the inner side of the receiving groove 121. The connecting hole 122 is located on one side of the movable groove 123. A support plate 13 is provided inside the receiving groove 121 to support the limiting rod 132 and drive the limiting rod 134. 32. A pressing block 134 is fixed to one side wall of the support plate 13 to control the movement of the support plate 13. The pressing block 134 passes through the movable groove 123. A limiting rod 132 is fixed to one side wall of the support plate 13 to limit the movement of the mounting ring 21. The limiting rod 132 is located on one side of the pressing block 134 and passes through the connecting hole 122. A limiting groove 213 is provided on the inner wall of the mounting ring 21. One end of the limiting rod 132 is movably inserted into the inner side of the limiting groove 213 to fix the mounting ring 21. A first spring 131 is fixed to the other side wall of the support plate 13. The support plate 13 is moved by the elastic support force. One end of the first spring 131 is fixed to the inner wall of the receiving groove 121. The inner wall of the mounting ring 21 has a notch 212, which provides space for the fixing strip 126. The outer wall of the rotating shaft 12 is fixed with the fixing strip 126. The fixing strip 126 passes through the notch 212, which ensures that the mounting ring 21 will not rotate outside the rotating shaft 12. The reinforcement component 2 of this solution is connected to the outside of the rotating shaft 12 through the mounting ring 21. The limiting rod 132 is inserted into the inner side of the limiting groove 213 to fix the mounting ring 21. By pressing the pressing block 134, the support plate 13 can be moved. The movement of the support plate 13 compresses the first spring 131 and drives the limiting rod 132 to disengage from the inner side of the limiting groove 213. The mounting ring 21 can then be moved and disassembled, thus completing the disassembly of the reinforcement component 2. This allows the factory to choose whether to use the reinforcement component 2 according to the weight of the transported items, improving flexibility and practicality. Example
[0028] In another embodiment of this solution, refer to Figure 1 , Figure 2 and Figure 5As shown, specifically, a rectangular groove 124 is provided on the inner wall of the other side of the receiving groove 121 to accommodate the plug-in plate 14 and the second spring 142. A toggle groove 125 is provided on one side of the inner wall of the rectangular groove 124 for the movement of the toggle block 141. The plug-in plate 14 is movably inserted into the inner side of the rectangular groove 124 to limit the position of the support plate 13. The plug-in plate 14 is located on one side of the support plate 13. A second spring 142 is fixed to one end of the plug-in plate 14 to apply an elastic thrust to the plug-in plate 14. One end of the second spring 142 is fixed to the inner wall of the rectangular groove 124. A toggle block 141 is fixed to one side of the plug-in plate 14 to control the movement of the plug-in plate 14. The toggle block 141 is located inside the toggle groove 125. One end of the support plate 13 is provided with a plug-in groove 133. The size of the plug-in groove 133 is adapted to the size of the plug-in plate 14. The plug-in plate 14 can be inserted into the plug-in groove 133 to restrict the movement of the support plate 13. This solution adds After the reinforcement component 2 is installed and fixed, the plug plate 14 is located on one side of the support plate 13, restricting the movement of the support plate 13 and preventing the support plate 13 from accidentally driving the limiting rod 132 out of the inner side of the limiting groove 213. When it is necessary to disassemble the reinforcement component 2, the plug plate 14 can be moved by using a tool to move the lever 141, which will compress the second spring 142 and make the plug plate 14 completely move into the inner side of the rectangular groove 124, thereby releasing the restriction on the support plate 13. After the support plate 13 drives the limiting rod 132 out of the inner side of the limiting groove 213, the rebound force of the second spring 142 can push the plug plate 14 into the inner side of the plug groove 133, restricting the movement of the support plate 13. This ensures that the limiting rod 132 will not block the movement and removal of the mounting ring 21, and the lever 141 is completely located inside the lever groove 125, so it will not affect the movement and removal of the mounting ring 21, thus making it easier to disassemble and assemble the reinforcement component 2. Example
[0029] In another embodiment of this solution, refer to Figure 1 , Figure 2 and Figure 3 As shown, specifically, a reinforcing component 2 is movably sleeved on the outside of the rotating shaft 12 to reinforce the roller body 1. The reinforcing component 2 includes a mounting ring 21 and a reinforcing ring 22. The mounting ring 21 is movably sleeved on the outside of the rotating shaft 12 to fix the reinforcing plate 211. The reinforcing plate 211 is fixed to the outer wall of the mounting ring 21 to support the reinforcing ring 22. The reinforcing ring 22 is fixed to one end of the reinforcing plate 211 to reinforce the roller body 1 from the inside. In this scheme, after the mounting ring 21 is fixed on the outside of the rotating shaft 12, the reinforcing ring 22 can support the roller body 1 from the inside, preventing the roller body 1 from deforming. Multiple reinforcing components 2 can support the roller body 1 at various points, ensuring that the roller body 1 will not be deformed when conveying heavy items, and extending the service life of the roller body 1.
[0030] The working principle and usage process of this utility model:
[0031] In use, when the roller body 1 is conveying heavier items, the reinforcing component 2 is located inside the roller body 1 to support various parts of the roller body 1 and prevent deformation. When conveying lighter items, a tool such as a flathead screwdriver is inserted into the actuating groove 125 to actuate the actuating block 141. The actuating block 141 drives the plug plate 14 to compress the second spring 142 and move it completely into the rectangular groove 124. At this time, the pressing block 134 is pressed, which drives the support plate 13 to move and compress the first spring 131. After compression, the support plate 13 moves the limiting rod 132 out of the inner side of the limiting groove 213, and the lever 141 is released. Under the action of the rebound force of the second spring 142, the plug plate 14 moves out of the inner side of the rectangular groove 124, and one end of the plug plate 14 is inserted into the plug groove 133 to limit the support plate 13 and prevent the limiting rod 132 from moving further. At this time, the mounting ring 21 can be moved to one end of the rotating shaft 12 for disassembly, thereby removing the reinforcing component 2, which reduces the weight of the roller body 1 and reduces energy consumption when conveying lighter items.
[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
