Description

Technical Field

[0001] This utility model relates to the field of idler roller technology, specifically to an idler roller assembly. Background Technology

[0002] Idler rollers are crucial components of belt conveyors, coming in various types and in large quantities. They support the conveyor belt and the weight of the materials. They account for 35% of the total cost of a belt conveyor and generate over 70% of the resistance, making their quality paramount. Idler rollers are available in both steel and plastic.

[0003] In existing idler roller assemblies, the assembly between the idler roller shaft and the mounting frame is mostly done by bolt limiting. This traditional assembly method requires a wrench and takes a considerable amount of time and effort, making it difficult to quickly assemble the idler roller and the mounting frame. It also makes it inconvenient to quickly disassemble the idler roller assembly during subsequent maintenance. Therefore, this utility model proposes an idler roller assembly that is easy to install. Utility Model Content

[0004] The purpose of this invention is to provide a roller assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a roller assembly, comprising: The system comprises two mounting brackets and a roller body, with the roller body positioned between the two mounting brackets. Each mounting bracket has a mounting groove on its top wall. A shaft is rotatably mounted at both ends of the roller body, and mounting rods are fixedly welded to the shafts. The two mounting rods are placed in the two mounting grooves respectively. A bidirectional lead screw is rotatably mounted between the two mounting brackets, with connecting rods on both sides of the bidirectional lead screw. The ends of the connecting rods are fixedly welded to the two mounting brackets respectively. Each mounting bracket is equipped with a sleeve mechanism, which includes two movable seats. Each movable seat has a screw hole and two through holes. The bidirectional lead screw is threaded into the screw hole, and the connecting rods are slidably connected into the through holes. Two sliding rods are fixedly welded to the movable seats and slidably connected to the mounting brackets. A sleeve plate is fixedly welded to the sliding rod, and the sleeve plate has a sleeve groove that matches the mounting rod.

[0006] Preferably, positioning posts are fixedly welded to the bottom walls of both of the two mounting slots, and positioning slots are provided on both of the mounting rods, with the positioning posts and positioning slots being adapted to each other.

[0007] Preferably, one end of the bidirectional lead screw extends to the outside of the corresponding mounting bracket, and a slot is formed on the surface of the extended portion of the bidirectional lead screw.

[0008] Preferably, a fixing seat is provided on one side of the slot, the fixing seat is fixedly welded to the mounting bracket at the corresponding position, and a threaded plug is threadedly connected to the fixing seat, the threaded plug being adapted to the slot.

[0009] Preferably, a handwheel is fixedly installed at the outer end of the bidirectional lead screw.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. In the process of using this utility model, when installing the idler roller body, the two support rods of the idler roller body can be placed into the two support slots respectively, and the positioning pins can be inserted into the positioning slots. Then, the handwheel is rotated forward to drive the bidirectional screw to rotate forward, so that the two moving seats move towards each other, and drive the two sleeve plates to move towards each other, so that the two support rods are inserted into the sleeve slots of the two sleeve plates respectively, thereby locking and fixing the two support rods. This realizes the convenient installation of the idler roller body. When disassembling, the handwheel is rotated in the reverse direction to separate the sleeve plates from the support rods, thus realizing convenient disassembly. This makes it easy to disassemble and assemble the idler roller body, which is convenient for maintenance and replacement. 2. The threaded insert rod of this utility model can be rotatably inserted into the slot, thereby locking and fixing the bidirectional screw and preventing the moving seat from deflecting unexpectedly.

[0013] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 This utility model provides a technical solution: a roller assembly, comprising: The system comprises two mounting brackets 1 and a roller body 2, with the roller body 2 positioned between the two mounting brackets 1. Each mounting bracket 1 has a mounting groove 3 on its top wall. Both ends of the roller body 2 are rotatably mounted with shafts 4, and mounting rods 5 are fixedly welded to the shafts 4. The two mounting rods 5 are respectively placed in the two mounting grooves 3. A bidirectional lead screw 6 is rotatably mounted between the two mounting brackets 1, and connecting rods 7 are respectively provided on both sides of the bidirectional lead screw 6. The two ends of the connecting rods 7 are respectively fixedly welded to the two mounting brackets 1. Each of the mounting brackets 1 is equipped with a connecting mechanism 8, which includes two movable seats 9. Each of the two movable seats 9 has a screw hole 10 and two through holes 11. The bidirectional lead screw 6 is threaded into the screw hole 10, and the connecting rod 7 is slidably connected into the through hole 11. Two sliding rods 12 are fixedly welded to the movable seat 9. The sliding rods 12 are slidably connected to the mounting bracket 1. A connecting plate 13 is fixedly welded to the sliding rod 12. A connecting groove 14 is provided on the connecting plate 13, and the connecting groove 14 is adapted to the mounting rod 5.

[0015] Positioning posts 15 are fixedly welded to the bottom walls of the two mounting slots 3, and positioning slots 16 are provided on the two mounting rods 5. The positioning posts 15 and the positioning slots 16 are adapted to each other. By the insertion and cooperation of the positioning posts 15 and the positioning slots 16, it is easy to limit the position of the mounting rods 5 after they are placed.

[0016] One end of the bidirectional lead screw 6 extends to the outside of the corresponding mounting bracket 1, and a slot 19 is provided on the surface of the extended portion of the bidirectional lead screw 6.
