Description
Technical Field
[0001] This utility model relates to the field of conveyor belt support roller technology, and in particular to an upper roller correction structure that is easy to maintain. Background Technology
[0002] The conveyor belt idler roller correction structure is a mechanical device used to automatically correct conveyor belt deviation. Its core purpose is to prevent belt wear, material spillage, or equipment damage caused by belt misalignment. This structure usually uses adjustable idler roller groups or self-aligning idler rollers. It detects the belt deviation in real time through mechanical sensing or gravity and automatically adjusts the idler roller angle or position to bring the conveyor belt back to the center line. Its design can effectively extend the service life of the conveyor belt, reduce material spillage, and ensure stable equipment operation.
[0003] If maintenance is required on the existing upper roller correction structure, the entire shaft connecting the idler needs to be disassembled. This process is not only time-consuming and labor-intensive, but also prone to damage or loss of parts. Since the disassembly process involves multiple connecting parts, the operating space is often limited, increasing the difficulty of maintenance. In addition, frequent disassembly and assembly can lead to a decrease in the accuracy of the shaft fit, affecting the stability of equipment operation. This design flaw significantly reduces maintenance efficiency and is not conducive to the implementation of daily maintenance work.
[0004] Therefore, to address the problem that the existing upper roller correction structure requires disassembling the entire shaft connecting the idler roller for maintenance, which is inconvenient and not conducive to daily maintenance, an upper roller correction structure that is easy to maintain can be designed. Utility Model Content
[0005] To overcome the problem that the existing upper roller correction structure requires disassembling the entire shaft connecting the idler rollers for maintenance, which is inconvenient and not conducive to daily maintenance.
[0006] The technical solution of this utility model is as follows: an easy-to-maintain upper roller correction structure, including a base, a first semi-cylinder and a second semi-cylinder. Four side supports are installed on the top of the base. Each of the four side supports is rotatably connected to a mounting shaft. A first semi-cylinder is provided on the outer rear side of each of the three mounting shafts, and a second semi-cylinder is provided on the outer front side of each of the three mounting shafts. The front surface of the first semi-cylinder has a mating groove on both the upper and lower sides. A mating block is installed on the rear side of the second semi-cylinder at the position corresponding to the mating groove. Mounting holes are provided at both the front and rear ends of the mating blocks. A spring is provided inside the mounting hole. A plug is installed at the end of the spring near the port of the corresponding mounting hole. Insertion holes are provided at both the front and rear ends of the first semi-cylinder at the positions corresponding to the plug.
[0007] Preferably, by setting the docking block and docking groove, the first and second semi-cylinders can be easily docked and assembled to form a complete idler roller. During assembly, the insert rods on both sides are pressed into the interior of the docking block, and then the docking block is inserted into the groove. When the insert rod moves to the insertion hole position, the spring's return force will push the insert rod into the insertion hole, thereby realizing the docking installation of the docking block and the docking groove. During maintenance, it is only necessary to press the insert rod into the interior of the docking block again for disassembly, without disassembling the mounting shaft of the side bracket, which improves the convenience of maintenance. This solves the problem that the existing upper roller correction structure requires the disassembly of the entire shaft connecting the idler roller when maintenance is needed, which is inconvenient during disassembly and assembly and not conducive to daily maintenance.
[0008] Preferably, locking grooves are provided on the outer sides of all four insertion rods, and two sets of locking components are provided at both the front and rear ends of the first semi-cylinder.
[0009] Preferably, the locking assembly includes adjusting bolts, connecting plates, and washers; two adjusting bolts are connected to both ends of the first semi-cylinder, a connecting plate is rotatably connected to the outside of each adjusting bolt, and a washer is also provided on the outside of each adjusting bolt.
[0010] Preferably, the locking assembly also includes a support block; the support block is installed at the end of the connecting piece away from the corresponding adjusting bolt, and the support block is in contact with the first semi-cylinder.
[0011] Preferably, the locking assembly also includes a locking block; the locking block is installed at the end of the support block away from the corresponding connecting piece, and the locking block is adapted to the locking groove.
[0012] Preferably, two screw holes are provided at both ends of the first and second semi-cylinders, and a connecting component is provided between the corresponding two screw holes.
[0013] Preferably, the connecting assembly includes a positioning plate and a fixing bolt; the positioning plate is provided between two corresponding screw holes, and the fixing bolt is installed on the front side of the positioning plate corresponding to the position of the two screw holes.
[0014] The beneficial effects of this utility model are:
[0015] By adopting a detachable assembly structure, the idler roller is designed as a combination of a first semi-cylinder and a second semi-cylinder. During maintenance, disassembly and assembly can be completed simply by separating the first semi-cylinder from the second semi-cylinder, without disassembling core components such as the idler roller shaft. This significantly improves the convenience of maintenance operations and avoids the risk of damage to the bearing housing during the disassembly and assembly of traditional integral idler rollers. It is suitable for high-frequency maintenance scenarios in conveyor systems, which can shorten equipment downtime and reduce the labor intensity of maintenance personnel, providing a reliable guarantee for continuous production.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Please see Figures 1-6This utility model provides an embodiment of an easy-to-maintain upper roller correction structure, including a base 1, a first semi-cylinder 4, and a second semi-cylinder 5. Four side supports 2 are mounted on the top of the base 1, and each pair of side supports 2 is rotatably connected to a mounting shaft 3. A first semi-cylinder 4 is provided on the outer rear side of each of the three mounting shafts 3, and a second semi-cylinder 5 is provided on the outer front side of each of the three mounting shafts 3. The front surface of the first semi-cylinder 4 has mating grooves 6 on both its upper and lower sides. A mating block 7 is installed on the rear side of the second semi-cylinder 5 at the position corresponding to the mating groove 6. Mounting holes 8 are provided at both the front and rear ends of the mating block 7. A spring 9 is installed inside the mounting hole 8, and a plug rod 10 is installed at the end of the spring 9 near the corresponding port of the mounting hole 8. The first semi-cylinder 4... The front and rear ends of the roller assembly have insertion holes 11 corresponding to the positions of the insertion rods 10. Through the cooperation structure of the docking block 7 and the docking groove 6, the first semi-cylinder 4 and the second semi-cylinder 5 can be quickly assembled to form a complete roller assembly. During assembly, after pressing the insertion rods 10 into the inner cavity of the docking block 7, the entire docking block 7 is inserted into the docking groove 6. When the insertion rod 10 moves to the corresponding position of the insertion hole 11, the elastic reset action of the spring 9 will drive the insertion rod 10 to automatically engage with the insertion hole 11, completing the mechanical interlock between the docking block 7 and the docking groove 6. During maintenance, it is only necessary to press the insertion rod 10 again to retract it into the docking block 7 to separate the assembly. The entire process does not require disassembling the mounting shaft 3 structure of the side bracket 2, which significantly improves the operational convenience of equipment maintenance.
[0025] Please see Figures 3-6 In this embodiment, locking grooves 12 are provided on the outer sides of all four insertion rods 10. Two sets of locking components are provided at both the front and rear ends of the first semi-cylinder 4. By providing the locking grooves 12, the locking components can be positioned by cooperating with the locking grooves 12 to prevent displacement during daily use. The locking components include adjusting bolts 131, connecting pieces 132, and washers 133. Two adjusting bolts 131 are connected to both the front and rear ends of the first semi-cylinder 4. Each adjusting bolt 131 has a connecting piece rotatably connected to its outer side. The connecting piece 132 is provided with a washer 133 on the outside of each adjusting bolt 131. By setting the adjusting bolt 131, the pressing force on the connecting piece 132 after the adjusting bolt 131 is tightened can realize the positioning of the connecting piece 132. The locking assembly also includes a support block 134. The end of the connecting piece 132 away from the corresponding adjusting bolt 131 is equipped with a support block 134. The support block 134 fits against the first semi-cylinder 4. By setting the support block 134, the support strength of the connecting piece 132 is improved.
[0026] Please see Figures 2-6In this embodiment, the locking assembly further includes a locking block 135; the locking block 135 is installed at the end of the support block 134 away from the corresponding connecting piece 132. The locking block 135 is adapted to the locking groove 12. By setting the locking block 135, when the connecting piece 132 is rotated, the locking block 135 can be inserted into the interior of the locking groove 12 to achieve locking. Two screw holes 14 are opened at both ends of the first semi-cylinder 4 and the second semi-cylinder 5. A connecting assembly is provided between the two corresponding screw holes 14. The connecting assembly can be installed by setting the screw holes 14. The connecting assembly includes a positioning piece 151 and a fixing bolt 152; the positioning piece 151 is provided between the two corresponding screw holes 14. The fixing bolt 152 is installed on the front side of the positioning piece 151 at the position corresponding to the two screw holes 14. By setting the positioning piece 151 and the fixing bolt 152, the connection strength between the first semi-cylinder 4 and the second semi-cylinder 5 can be strengthened, and the stability during use can be improved.
[0027] When maintenance is required, loosen the fixing bolt 152 to remove the positioning piece 151, and then loosen the adjusting bolt 131 to allow the connecting piece 132 to rotate. Rotating the connecting piece 132 will cause the locking block 135 to exit from the locking groove 12 of the insert rod 10. Then, press the insert rod 10 into the mounting hole 8 of the mating block 7, causing the spring 9 to be compressed. At this time, the mating block 7 can be removed from the mating groove 6, thereby separating the first semi-cylinder 4 and the second semi-cylinder 5. When reassembly is required after maintenance, press the insert rod 10 into the mounting hole 8 of the mating block 7. When the insert rod 10 moves to the insertion hole 11, the rebound force of the spring 9 will push the insert rod 10 into the insertion hole 11, thereby achieving the mating installation of the mating block 7 and the mating groove 6.
[0028] Through the above steps, quick assembly and disassembly are achieved through the cooperation of the docking block 7 and the docking groove 6. During assembly, the insert rods 10 on both sides of the docking block 7 are pressed inward to retract them into the interior and compress the spring 9. Then, the docking block 7 is inserted into the docking groove 6 axially. When the insert rod 10 moves to the insertion hole 11, the spring 9 rebounds and pushes the insert rod 10 to automatically engage with the insertion hole 11, completing the stable connection between the first semi-cylinder 4 and the second semi-cylinder 5, forming a complete idler roller. During maintenance, it is only necessary to press the insert rod 10 to disengage it from the insertion hole 11, and the docking block 7 can be pulled out from the docking groove 6. This achieves non-destructive maintenance of the side bracket 2 and the mounting shaft 3 without disassembling them, greatly improving the assembly and disassembly efficiency and reducing maintenance costs. This solves the problem that if the existing upper roller correction structure needs to maintain the idler roller, the entire shaft connecting the idler roller needs to be disassembled, which is inconvenient during assembly and disassembly and is not conducive to daily maintenance.
