Description

Technical Field

[0001] This utility model relates to the field of material conveying, and in particular to a combined transition device at the corner of a multi-angled angled belt conveyor. Background Technology

[0002] Materials such as construction waste typically require long-distance transport, and belt conveyors are commonly used for this purpose. However, due to site shape and size limitations, angled belt conveyors are sometimes necessary for their installation. Figure 1 The angled belt conveyor shown includes a first frame 1, a second frame 2, a belt 3, an idler assembly 7, and a stop assembly 8. The first frame 1 is horizontally arranged, and the second frame 2 is arranged at an angle. Idler assemblies 7 are installed on both the first frame 1 and the second frame 2. The belt 3 cooperates with the idler assemblies 7, and the idler assemblies 7 support the belt 3. The stop assembly 8 is set above the belt 3 to prevent material from overflowing from the belt 3. An angle (angle) is formed between the first frame 1 and the second frame 2, and this angle is 160°. To adapt the belt 3 to the first frame 1 and the second frame 2, a belt pressing mechanism A is installed at the angle between the first frame 1 and the second frame 2. The belt pressing mechanism A applies pressure to the belt 3 to change the angle of the belt 3.

[0003] like Figure 2 and Figure 3 As shown, the belt pressing mechanism A includes a bracket 4, a rotating shaft 5, and a pressing wheel 6. The lower end of the bracket 4 is fixed to the first frame 1, and a bearing seat is installed on the upper end of the bracket 4. A bearing is installed on the bearing seat, and the rotating shaft 5 is connected to the bearing. The pressing wheel 6 is fixed to the rotating shaft 5 and mates with the surface of the belt 3. Figure 1 and Figure 2 It can be seen that the belt 3 and the idler assembly 7 form a groove structure. Due to the large angle of the bend, the pressure roller 6 has to be arranged inside the baffle assembly 8. As a result, the part of the belt 3 between the two baffle assemblies 8 is the material conveying area. Based on the above structure, the material passing through this area is blocked or restricted by the pressure roller 6, which significantly reduces the effective bandwidth of the material. This greatly reduces the conveying efficiency of the entire belt conveyor. Utility Model Content

[0004] This invention provides a combined transition device at the corner of a multi-angled belt conveyor, which can improve the material conveying efficiency.

[0005] The technical solutions to the above technical problems are as follows: A combined transition device at the corners of a multi-angle belt conveyor is provided. This combined transition device is installed in each corner area of ​​the belt conveyor. The combined transition device includes an idler roller assembly supporting the support belt, and further includes: A guide roller assembly arranged on the left and right sides of the belt to limit its movement; A pressure roller assembly arranged outside the material stop assembly and pressing against the upper surface of the belt.

[0006] Furthermore, limiting components are arranged on the left and right sides of the belt to limit the range of movement of the belt in the vertical direction.

[0007] Furthermore, the guide roller assembly includes a first bracket and a guide roller that rotates when friction is generated between it and the belt, with the first bracket connected to the guide roller.

[0008] Furthermore, the pressure roller assembly includes a second support and a pressure roller that rotates when friction is generated between it and the belt, and the pressure roller is connected to the second support.

[0009] Furthermore, the pressure roller assembly also includes a connecting rod, a bearing, and a first nut. A portion of the connecting rod is threaded. The bearing is sleeved on the connecting rod and fixed to it. The pressure roller is sleeved on the bearing. The connecting rod passes through a second bracket. The first nut is threadedly connected to the connecting rod. There are multiple first nuts, which clamp the second bracket.

[0010] Furthermore, the limiting component includes a third bracket and a limiting plate, the limiting plate being fixed to the third bracket, and the limiting plate being provided with a receiving groove for clearance matching with the belt.

[0011] Furthermore, the limiting assembly also includes an adjusting assembly for adjusting the up and down position of the limiting plate. The adjusting assembly includes a screw and a second nut. The third bracket is provided with a strip hole, through which the screw passes and connects to the second nut.

[0012] Furthermore, the limiting component also includes a protective component, which is located within the receiving groove and fixed to the limiting plate.

[0013] In this invention, the left and right sides of the belt are limited by the guide roller assembly, which greatly reduces the belt deviation at the bend. The pressure roller assembly is arranged outside the guide roller assembly and applies pressure to the belt. In this way, the pressure roller assembly does not occupy the material conveying area of ​​the belt and will not block the conveyed material, thereby increasing the effective passage width of the material and improving the material conveying efficiency.

Detailed Implementation

[0024] like Figures 4 to 8 As shown, the present invention relates to a combined transition device at the corners of a multi-angled belt conveyor. In this embodiment, the belt conveyor has multiple corners. By setting multiple corners, the angle of each corner can be reduced. For example, in this embodiment, the belt conveyor has three corners, and the angle of each corner is less than 5°. Therefore, in this invention, the combined transition device C is installed in each corner area of ​​the belt conveyor. Each set of combined transition devices C includes a roller assembly 7 supporting the belt 3, a stop roller assembly, a pressure roller assembly, and a limiting assembly. Each part will be described in detail below.

[0025] On the left or right side of belt 3, there are multiple idler roller assemblies 7 and guide roller assemblies in each set of combined transition devices. For example, there are 3 idler roller assemblies 7 and 2 guide roller assemblies. The first idler roller assembly 7 is arranged between the first guide roller assembly and the pressure roller assembly. The second idler roller assembly 7 is arranged between the pressure roller assembly and the limiting assembly. The third idler roller assembly 7 is arranged between the limiting assembly and the second guide roller assembly. The idler roller assembly 7 preferably adopts a trough-shaped idler roller. When belt 3 and idler roller assembly 7 are matched, belt 3 also becomes trough-shaped.

[0026] The guide roller assemblies are arranged on the left and right sides of the belt 3 and limit the movement of the belt 3. There is a gap between the guide roller assemblies on the left and right sides of the belt 3 and the belt 3. The guide roller assemblies limit the range of movement of the belt 3 in the left and right directions. The guide roller assembly includes a first support 11 and a guide roller 12 that rotates when friction is generated between it and the belt 3. The first support 11 is fixed to the frame of the angled belt conveyor and is connected to the guide roller 12. The guide roller 12 and the first support 11 can be movably connected. For example, the guide roller 12 consists of a guide roller body and a connecting shaft. The guide roller body is fixedly connected to the connecting shaft, and the first support 11 is equipped with a bearing. The connecting shaft is connected to the bearing. Alternatively, the guide roller 12 and the first support 11 can be movably connected. For example, the guide roller 12 consists of a guide roller body, a connecting shaft, and a bearing. The connecting shaft passes through the inner ring of the bearing and is fixed to the first support 11. The guide roller body is fitted onto the outer ring of the bearing with an interference fit.

[0027] The pressure roller assembly is arranged outside the material stop assembly 8 and presses against the upper surface of the belt 3. Pressure roller assemblies are arranged on both the left and right sides of the belt 3. Each pressure roller assembly includes a second support 13 and a pressure roller 14 that rotates when friction is generated between it and the belt 3. The pressure roller 14 is connected to the second support 13 and exerts pressure on the belt 3, thus maintaining the grooved structure of the belt 3. In this invention, because the pressure roller assembly is arranged outside the material stop assembly 8, it does not occupy the material conveying area of ​​the belt 3 and does not obstruct the conveyed material, thereby improving the material conveying efficiency.

[0028] The pressure roller assembly also includes a connecting rod 15, a bearing 16, and a first nut 17. A portion of the connecting rod 15 is threaded. The bearing 16 is fitted onto and fixed to the connecting rod 15. The pressure roller 14 is fitted onto the bearing 16. The connecting rod 15 passes through a second bracket 13. The first nut 17 is threadedly connected to the connecting rod 15. Multiple first nuts 17 are present and clamp the second bracket 13. The structure of the first nut 17 and the connecting rod 15 allows for adjustment of the engagement length between the pressure roller 14 and the belt 3.

[0029] The limiting components are arranged on the left and right sides of the belt 3 and restrict the range of movement of the belt 3 in the vertical direction. The limiting components include a third bracket 18 and a limiting plate 19. The limiting plate 19 is fixed to the third bracket 18, and the limiting plate 19 is provided with a receiving groove 20 for clearance fit with the belt 3. The receiving groove 20 has an upper inner wall, a lower inner wall, and a bottom wall. There is a gap between the belt 3 and the upper inner wall, the lower inner wall, and the bottom wall. Preferably, the gap between the belt 3 and the bottom wall of the receiving groove 20 is less than or equal to the gap between the belt 3 and the guide roller assembly. In this way, the limiting components can also restrict the movement of the belt 3 in the left or right direction.

[0030] The limiting assembly also includes an adjusting component for adjusting the vertical position of the limiting plate 19. The adjusting component includes a screw 21 and a second nut 22. The third bracket 18 has a strip hole 19a, through which the screw 21 passes and connects to the second nut 22. The adjusting component allows for adjustment of the distance between the belt 3 and the upper and lower inner walls of the receiving groove 20 as needed.

[0031] The limiting component also includes a protective component 23, which is located in the receiving groove 20 and fixed to the limiting plate 19. Since the limiting plate 19 is made of metal, the protective component 23 can be made of materials with low friction coefficients such as polytetrafluoroethylene, polyoxymethylene, modified nylon, or ultra-high molecular weight polyethylene. After the protective component 23 is installed in the receiving groove 20 on the limiting plate 19, if the belt 3 rubs against the limiting component, the protective component 23 can reduce the friction between the belt 3 and the belt 3, thereby reducing the wear of the belt 3.

Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of this application are still within the scope of this application.
