Description

Technical Field

[0001] This utility model relates to the field of redirecting roller technology, specifically to an adjustable redirecting roller device. Background Technology

[0002] The redirecting roller is a key component of a belt conveyor, primarily used to change the running direction of the conveyor belt or to tighten the conveyor belt to increase the wrap angle with the drive roller. It is commonly found in industries such as metallurgy, mining, and ports. The redirecting roller is usually located below the conveyor belt; if the conveyor belt's direction of travel is left-hand, then the redirecting roller is on the right side of the belt conveyor. The principle of the redirecting roller is to change the direction of material movement through the rotation of the roller. The drive motor transmits power to the roller, causing it to rotate rapidly, thereby changing the direction of material movement. As the roller rotates, the material is drawn and redirected, thus achieving the purpose of material transport.

[0003] Currently, the length of existing deflector rollers is determined during manufacturing and cannot be adjusted later. This means that when factories use deflector rollers to transport materials, they need to customize deflector rollers of the corresponding specifications according to the size of the materials and the width of the belt. The cost of custom-made deflector rollers is undoubtedly much higher than the cost of purchasing deflector rollers, thereby increasing the factory's production costs and hindering the factory's cost reduction and efficiency improvement.

[0004] Therefore, there is a need for an adjustable redirecting roller device that can adjust the length of the redirecting roller. Utility Model Content

[0005] To address the aforementioned issues, this invention proposes an adjustable redirecting roller device that allows for self-adjustment of the roller's length during use, adapting to different belt and material sizes, thereby helping to reduce factory production costs.

[0006] To achieve the above objectives, the present invention proposes the following specific solutions:

[0007] An adjustable redirecting roller device includes a first roller, a fixed plate fixed to the inner wall of the middle part of the first roller, threaded columns symmetrically fixed to the middle of the side wall of the fixed plate, a connecting shaft fixed to one end of the threaded column, and a threaded tube threadedly connected to the outer side of the threaded column. Second rollers are symmetrically arranged on both sides of the first roller, the second rollers being located outside the threaded tube. A support plate is fixed to the inner wall of one end of the second roller, four support plates are provided, a connecting ring is fixed to one end of the support plate, the connecting ring is movably sleeved on the outer side of the threaded tube, an adjusting groove is symmetrically arranged on the side wall of the first roller, and an adjusting plate is fixed to one side wall of the second roller, the adjusting plate being movably inserted into the inner side of the adjusting groove.

[0008] As a preferred technical solution of the adjustable redirecting roller device of this utility model, a threaded cylinder is fixed to the outer wall of one end of the threaded tube, the threaded cylinder is connected to the inner side of the threaded tube, and a screw is threadedly connected to the inner side of the threaded cylinder.

[0009] As a preferred technical solution of the adjustable redirecting roller device of this utility model, a first limiting ring is fixedly sleeved on the outer wall of the other end of the threaded pipe, and the first limiting ring is located on one side of the connecting ring.

[0010] As a preferred technical solution of the adjustable redirecting roller device of this utility model, a second limiting ring is fixed on the outer wall of the threaded pipe, and the second limiting ring is located on the other side of the connecting ring.

[0011] As a preferred technical solution of the adjustable redirecting roller device of this utility model, the side wall of the fixed disk is provided with weight reduction holes, the weight reduction holes penetrate the fixed disk, and there are four weight reduction holes.

[0012] As a preferred technical solution of the adjustable redirecting roller device of this utility model, the size of the adjusting plate is adapted to the size of the adjusting groove.

[0013] As a preferred embodiment of the adjustable redirecting roller device of this utility model, multiple adjustment plates and adjustment grooves are provided.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The first roller of this invention has threaded columns symmetrically fixed to the side wall of the fixed plate on its inner wall. A threaded tube is threadedly connected to the outside of the threaded column. When the threaded tube rotates, it can move along the direction of the threaded column. The second roller has a support plate fixed to its inner wall. A connecting ring is fixed to one end of the support plate. The connecting ring is movably sleeved on the outside of the threaded tube. The movement of the connecting ring is restricted by the first and second limiting rings, so that when the threaded tube moves, it can drive the connecting ring to move, thereby driving the second roller to move. The distance between the second roller and the first roller can be adjusted to change the overall length of the redirecting roller. This can be adjusted according to different belt widths and material sizes, saving the cost of custom-made redirecting rollers in the factory.

[0016] The first roller of this utility model is provided with multiple adjustment grooves, and the side wall of the second roller is provided with multiple adjustment plates. The adjustment plates are located inside the adjustment grooves. When the second roller moves, it can drive the adjustment plates to move inside the adjustment grooves, so that the multiple adjustment plates can fill the gap between the second roller and the first roller. The circle formed by the multiple adjustment plates supports the belt, effectively preventing the belt from being dented due to material pressure, and ensuring the reliability of this solution.

[0024] 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 scope of protection of the present utility model. Example

[0025] Please see Figure 1-5 As shown, the present invention provides the following technical solution: an adjustable redirecting roller device, including a first roller 1, a fixing plate 12 fixed on the inner wall of the middle part of the first roller 1, and a weight reduction hole 121 provided on the side wall of the fixing plate 12. The weight reduction hole 121 penetrates the fixing plate 12, and there are four weight reduction holes 121. The fixing plate 12 can support the first roller 1, and the weight reduction hole 121 can reduce the overall weight, which helps to reduce energy consumption.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, specifically, second rollers 3 are symmetrically arranged on both sides of the first roller 1 to form a complete redirecting roller. The second rollers 3 are located outside the threaded tube 2. A support plate 32 is fixed to the inner wall of one end of the second roller 3 to support it. There are four support plates 32. A connecting ring 321 is fixed to one end of the support plate 32. The connecting ring 321 is movably sleeved on the outside of the threaded tube 2 and connected to the threaded tube 2 through the connecting ring 321, so that the threaded tube 2 can drive the second roller 3 to move. A first limiting ring 21 is fixedly sleeved on the outer wall of the other end of the threaded tube 2. The first limiting ring 21 is located on one side of the connecting ring 321. A second limiting ring 22 is fixed to the wall, located on the other side of the connecting ring 321. The first limiting ring 21 and the second limiting ring 22 are located on both sides of the connecting ring 321, preventing the connecting ring 321 from moving outside the threaded tube 2. In this solution, the threaded tube 2 rotates and moves along the threaded post 122, which can drive the connecting ring 321 to move. The connecting ring 321 drives the second roller 3 to move through the support plate 32, so that the distance between the second roller 3 and the first roller 1 can be adjusted, thereby achieving the purpose of adjusting the length of the redirecting roller. This makes it convenient for the factory to adjust the use according to the material size and belt length, without the need to customize the redirecting roller separately, thus saving costs. Example

[0027] In another embodiment of this solution, refer to Figure 1 , Figure 2 and Figure 4 As shown, specifically, the first roller 1 has symmetrically arranged adjustment grooves 11 on its side wall for connecting adjustment plates 31, which can prevent the second roller 3 from rotating relative to the first roller 1. An adjustment plate 31 is fixed on one side wall of the second roller 3, which supports the belt at the corresponding position after adjusting the length of the redirecting roller. The adjustment plate 31 is movably inserted into the inside of the adjustment groove 11, and the size of the adjustment plate 31 is adapted to the size of the adjustment groove 11. Multiple adjustment plates 31 and adjustment grooves 11 are provided. In this scheme, when the second roller 3 moves, the adjustment plate 31 can also move inside the adjustment groove 11. The gap between the second roller 3 and the first roller 1 is filled by multiple adjustment plates 31 to provide comprehensive support for the belt, prevent the belt from denting, and enhance reliability. Example

[0028] In another embodiment of this solution, refer to Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, specifically, threaded posts 122 are symmetrically fixed in the middle of the side wall of the fixed plate 12 for connecting the threaded tube 2. A connecting shaft 123 is fixed at one end of the threaded post 122 for connecting with the bearing. The threaded tube 2 is threadedly connected to the outside of the threaded post 122. When the threaded tube 2 rotates, it can move along the direction of the threaded post 122. A threaded cylinder 23 is fixed to the outer wall of one end of the threaded tube 2 for connecting the screw 24. The threaded cylinder 23 is connected to the inside of the threaded tube 2. The screw 24 is threadedly connected to the inside of the threaded cylinder 23, which can fix the threaded tube 2. This solution fixes the threaded tube 2 by pressing one end of the screw 24 against the threaded post 122, ensuring that the threaded tube 2 will not accidentally rotate outside the threaded post 122 during operation, thus improving stability.

[0029] The working principle and usage process of this utility model:

[0030] When in use, select a belt of appropriate width according to the size of the material. Based on the belt width, rotate the threaded tube 2. When the threaded tube 2 rotates outside the threaded post 122, it will move along the direction of the threaded post 122. The movement of the threaded tube 2 can drive the connecting ring 321 to move. The connecting ring 321 drives the second roller 3 to move through the support plate 32, thereby adjusting the distance between the second roller 3 and the first roller 1, and thus adjusting the length of the redirecting roller to match the width of the belt. By tightening the screw 24, one end of the screw 24 is pressed against the threaded post 122, which can restrict the rotation of the threaded tube 2, thereby preventing the threaded tube 2 from rotating accidentally during operation. When the second roller 3 moves, multiple adjusting plates 31 will also move inside multiple adjusting grooves 11. The multiple adjusting plates 31 will fill the gap between the second roller 3 and the first roller 1, support the belt, and prevent the belt from denting.

[0031] 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.
