Description

Technical Field

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

[0002] Idler rollers are important components of belt conveyors, playing a crucial role in supporting the conveyor belt and the weight of materials in the conveying system. They consist of roller bodies, bearings, seals, etc. According to their functions, they can be divided into various types such as trough idlers and parallel idlers. Idler rollers are characterized by flexible rotation, wear resistance, and long service life. They can reduce the running resistance of the conveyor belt and ensure efficient and stable conveying operations.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] Existing segmented idlers generally require adjustment based on the actual usage conditions before they can be put into use. When conveying different types of items, the operating angle of the device needs to be changed frequently. However, changing the angle of the existing device is quite cumbersome, requiring the device casing to be disassembled first, followed by manual angle adjustment, and then the casing to be reinstalled. This is cumbersome and can easily reduce efficiency. Utility Model Content

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a segmented idler roller, including a fixed base 1, two support columns 15 slidably mounted on the upper end of the fixed base 1, an mounting frame 2 slidably mounted on the upper end of the fixed base 1, a first idler roller body 29 rotatably mounted on the upper end of the mounting frame 2, limit frames 3 rotatably mounted on both the left and right sides of the mounting frame 2, a second idler roller body 36 rotatably mounted inside each limit frame 3, a threaded rotating rod 12 rotatably mounted inside the fixed base 1, a drive motor 13 mounted on the side end of the threaded rotating rod 12, two first sliding collars 14 sleeved on the outer surface of the threaded rotating rod 12, a support column 15 fixedly mounted on the upper end of each first sliding collar 14, and a first fixing ring 16 fixedly mounted on the upper end of each support column 15.

[0022] In this embodiment, as Figure 1 and Figure 2 As shown, a support leg 11 is fixedly installed at the lower end of the fixed base 1, and a support rod 21 is fixedly installed at the lower end of the mounting bracket 2. First bolts 22 are slidably installed at the four corners of the support rod 21.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the mounting bracket 2 is slidably mounted on the fixed base 1 through the support rod 21, the first bolt 22 and the opening on the top of the fixed base 1. The second fixing ring 23 is fixedly installed on both the left and right sides of the mounting bracket 2.

[0024] In this embodiment, as Figure 1 and Figure 3 As shown, each second fixing ring 23 has a second bolt 24 slidably installed inside, and each second bolt 24 has a nut 25 fitted on its outer surface.

[0025] In this embodiment, as Figure 1 and Figure 3 As shown, two first rotating disks 26 are rotatably mounted on the upper end of the mounting frame 2. A first fixed handle 27 is rotatably mounted on the side end of one of the first rotating disks 26. A first spring 28 is sleeved on the outer surface of the first fixed handle 27. The same first idler roller body 29 is slidably mounted between each of the first rotating disks 26.

[0026] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, a fourth fixing ring 34 is fixedly installed on the side end of the limiting frame 3, a fixing post 31 is fixedly installed inside the limiting frame 3, a second sliding collar 32 is sleeved on the outer surface of the fixing post 31, a third fixing ring 33 is fixedly installed at the lower end of the second sliding collar 32, and the third fixing ring 33 is rotatably installed on the outer surface of the first fixing ring 16.

[0027] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, two second rotating disks 35 are rotatably installed inside the limiting frame 3. A second fixed handle 37 is rotatably installed on the side end of one of the second rotating disks 35. A second spring 38 is sleeved on the outer surface of the second fixed handle 37. The same second idler roller body 36 is slidably installed between each of the second rotating disks 35.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the segmented idler roller operates as follows during use:

[0029] First, the user starts the drive motor 13, which drives the threaded rod 12 to rotate. This, in turn, adjusts the positions of the two first sliding collars 14, causing them to move closer or further apart. As the first sliding collars 14 move, they pull the upper first fixed ring 16, causing it to move as well. This, in turn, pulls the third fixed ring 33 and the second sliding collar 32 to slide along the fixed post 31. At this time, the side end of the limiting frame 3 is connected to the second fixed ring 23 and the second bolt 24 via the fourth fixed ring 34. Therefore, when the second sliding collar 32 slides along the fixed post 31, it drives the limiting frame 3 to rotate along the fourth fixed ring 34. This allows for quick adjustment of the operating angle of the limiting frame 3 and the second idler roller body 36. When the device has been used for a long time and the idler roller needs to be disassembled and replaced, the user pulls the first fixed handle 27. The fixed handle 27 drives the connected first rotating disk 26 to slide, thereby compressing the first spring 28 and pulling the first rotating disk 26 out from one side of the first idler body 29. Then, the user removes the first idler body 29 from between the two first rotating disks 26 and replaces it. The replaced first idler body 29 is reinstalled on one side of the first rotating disk 26. At this time, the first fixed handle 27 is released, and the first rotating disk 26 is pushed back onto one side of the first idler body 29 under the action of the first spring 28. Similarly, the second fixed handle 37 is pulled to move the second rotating disk 35 away from the side of the second idler body 36. Then, the second idler body 36 is replaced. Then, the second fixed handle 37 is released, and the second rotating disk 35 rebounds under the action of the second spring 38, thereby reinstalling the second rotating disk 35 on the side of the second idler body 36.
