Description

Technical Field

[0001] This utility model relates to the technical field of conveyors, and in particular to an adjustment device for belt conveyor idler roller assembly. Background Technology

[0002] Belt conveyors are a widely used continuous conveying equipment in industrial production, primarily used for transporting bulk materials or packaged goods. One of their core components is the idler assembly, which supports the conveyor belt and reduces its running resistance, ensuring smooth and efficient operation. In practical applications, the installation angle and support configuration of the idler assembly have a significant impact on the conveyor belt's trajectory, wear level, and overall equipment efficiency.

[0003] However, traditional idler assemblies typically use a fixed installation structure, and the support angle of the idlers is not adjustable. When the weight and volume of the raw materials are small, they are easily affected by vibrations and other factors, causing them to wander off the conveyor belt or even deviate from it. Therefore, an adjustable idler structure is needed to solve this problem. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a highly adaptable and easy-to-operate belt conveyor idler roller adjustment device.

[0005] The belt conveyor idler roller adjustment device of this utility model includes:

[0006] The mounting base is independently fixed, and two support frames are symmetrically arranged at the top of the mounting base;

[0007] Two mounting shafts are rotatably mounted in the inner holes of two support frames, and extension columns are vertically mounted on the mounting shafts;

[0008] Two idler rollers are coaxially mounted on two extension columns and can rotate freely around the extension columns;

[0009] Two extension shafts are coaxially and rotatably installed inside the shaft cavities of two idlers. The extension shafts are coaxially arranged with the extension column and are slidably installed along the length of the idler. A support shaft is vertically arranged on the extension column and is parallel to the rotation axis of the mounting shaft.

[0014] The positioning mechanism is installed on the mounting base and is used to limit the movement trajectory of the mounting base.

[0015] Two auxiliary mechanisms are symmetrically arranged at both ends of the mounting base. The auxiliary mechanisms are used to support the conveyor belt in the middle of the two idlers.

[0016] As a preferred option, the positioning mechanism includes:

[0017] The positioning column is installed on the mounting base, and the length direction of the positioning column is parallel to the movement trajectory of the mounting base;

[0018] The limiting seat is installed on the mounting base by the first bolt, and the positioning column is slidably installed in cooperation with the positioning hole of the limiting seat.

[0019] Furthermore, the auxiliary mechanisms include:

[0033] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0034] This utility model relates to an adjusting device for a belt conveyor idler assembly, such as... Figures 1 to 5 As shown, it includes:

[0035] Mounting base 1 is independently fixed. Two support frames 2 are symmetrically arranged at the top of the mounting base 1. The support frames 2 are used to install and support other components.

[0036] Two mounting shafts 3 are rotatably mounted in the inner holes of two support frames 2, and an extension column 4 is vertically mounted on the mounting shafts 3;

[0037] Two idler rollers 5 are coaxially mounted on two extension columns 4 respectively, and can rotate freely around the extension columns 4 to facilitate the operation of the conveyor belt;

[0038] Two extension shafts 6 are coaxially and rotatably installed inside the shaft cavities of the two idler rollers 5. The extension shafts 6 are coaxially arranged with the extension column 4, and the extension shafts 6 are slidably installed along the length of the idler roller 5. A support shaft 7 is vertically arranged on the extension column 4, and the support shaft 7 is parallel to the rotation axis of the mounting shaft 3.

[0039] The adjustment mechanism 8 is mounted on the mounting base 1, and two support shafts 7 are rotatably mounted on the adjustment mechanism 8. The adjustment mechanism 8 is used to adjust the support angle of the idler roller 5.

[0040] The working principle of this device is as follows:

[0041] First, the support angle of the idler roller 5 is adjusted by the adjustment mechanism 8. The adjustment mechanism 8 rotates the support shaft 7, which drives the extension column 4 and the idler roller 5 to rotate around the mounting shaft 3, thereby changing the tilt angle of the idler roller 5. After the tilt angle of the idler roller 5 is adjusted, the running trajectory of the conveyor belt on the idler roller 5 will also be adjusted accordingly to ensure that the conveyor belt runs smoothly and efficiently.

[0042] The independently fixed mounting base 1 provides a solid and stable foundation for the entire device. Two symmetrically arranged support frames 2 at its top precisely install and firmly support the mounting shaft 3, providing a reliable support for the installation and operation of subsequent components. The extension column 4, which is vertically arranged on the mounting shaft, is coaxially installed with the idler roller 5, allowing the idler roller 5 to rotate freely around the extension column 4, greatly reducing the frictional resistance during the operation of the conveyor belt. The extension shaft 6 is coaxially rotatably installed inside the shaft cavity of the idler roller 5 and can slide along the length of the idler roller 5, providing flexible adjustment possibilities for the idler roller 5 under different working conditions, which helps to adapt to different operating states of the conveyor belt. In conjunction with the adjustment mechanism 8 installed on the mounting base 1, the extension column 4 and the idler roller 5 can be easily rotated around the mounting shaft by rotating the support shaft 7, so as to accurately adjust the support angle of the idler roller 5, thereby effectively adjusting the running trajectory of the conveyor belt on the idler roller and ensuring that the conveyor belt always operates smoothly and efficiently.

[0043] As a preferred option, such as Figures 1 to 4As shown, the adjustment mechanism 8 includes:

[0044] The adjusting tube 81 is rotatably installed in the inner hole of the mounting base 1, and a threaded tube 82 is installed inside the adjusting tube 81;

[0045] Mounting base 83 is mounted on threaded pipe 82, and both support shafts 7 are rotatably mounted on mounting base 83;

[0046] The positioning mechanism 84 is installed on the mounting base 1 and is used to limit the movement trajectory of the mounting base 83.

[0047] Two auxiliary mechanisms 85 are symmetrically arranged at both ends of the mounting base 83. The auxiliary mechanisms 85 are used to support the conveyor belt in the middle of the two idlers 5.

[0048] The adjusting pipe 81, which is rotatably installed in the inner hole of the mounting base 1, has a threaded pipe 82 installed inside. When the adjusting pipe 81 rotates, it can drive the mounting seat 83 to move through the threaded transmission. This design makes the adjustment of the support angle of the idler roller 5 more precise and stable. The mounting seat 83 is installed on the threaded pipe 82, and the two support shafts 7 are rotatably installed on it, ensuring that the idler roller 5 can be effectively driven to rotate around the mounting shaft 3 during the adjustment process, so as to achieve flexible adjustment of the tilt angle. The positioning mechanism 84 is installed on the mounting base 1 to limit the movement trajectory of the mounting seat 83, so as to avoid the mounting seat 83 from shifting or shaking during the adjustment process, and to ensure the accuracy and reliability of the adjustment. The two auxiliary mechanisms 85 symmetrically arranged at both ends of the mounting seat 83 can support the conveyor belt in the middle of the two idler rollers 5, enhance the stability of the conveyor belt during operation, reduce the sagging and shaking of the conveyor belt in the middle, and extend the service life of the conveyor belt and the idler roller.

[0049] As a preferred option, such as Figures 1 to 5 As shown, the positioning mechanism 84 includes:

[0050] Positioning post 84a is installed on mounting base 83, and the length direction of positioning post 84a is parallel to the movement trajectory of mounting base 83;

[0051] The limiting seat 84b is installed on the mounting base 1 by the first bolt 84c, and the positioning post 84a is slidably installed in cooperation with the positioning hole of the limiting seat 84b.

[0052] The positioning column 84a, mounted on the mounting base 83 and parallel to the moving trajectory of the mounting base 83 in the length direction, can accurately reflect the moving direction of the mounting base 83. The limiting seat 84b, which is mounted on the mounting base 1 by the first bolt 84c, has a positioning hole that slides in conjunction with the positioning column 84a, which can effectively constrain the moving path of the positioning column 84a. When adjusting the support angle of the idler roller 5, when the adjusting tube 81 rotates and drives the mounting base 83 to move, the positioning column 84a slides smoothly in the positioning hole of the limiting seat 84b, preventing the mounting base 83 from deviating, shaking or jamming during the movement, and ensuring that the mounting base 83 moves strictly according to the predetermined trajectory. This makes the adjustment mechanism 8 more precise and stable in adjusting the tilt angle of the idler roller 5, and ensures the accuracy of the conveyor belt running trajectory adjustment.

[0053] As a preferred option, such as Figures 1 to 5 As shown, the auxiliary mechanism 85 includes:

[0054] The connecting seat 85a is mounted on the mounting seat 83 by the second bolt 85b, and the connecting seat 85a is provided with an auxiliary bracket 85c;

[0055] The auxiliary roller 85d is rotatably mounted on the support frame 2. The auxiliary roller 85d is used to support the conveyor belt in the middle position between the two idler rollers 5.

[0056] The bolt of the connecting seat 85a passes through a long slot hole, which is used to adjust the height of the auxiliary roller 85d. A limit groove is provided on the wall of the long slot hole.

[0057] The elongated slot allows the second bolt 85b to move within it, thereby facilitating the adjustment of the height of the auxiliary roller 85d. The support height of the auxiliary roller 85d can be flexibly adjusted according to the actual operating requirements of different conveyor belts, material characteristics, and conveying conditions, ensuring that the conveyor belt always maintains optimal operating conditions and improving the versatility and adaptability of the device.

[0058] As a preferred option, such as Figures 1 to 5 As shown, a limiting member 85e is installed on the second bolt 85b, and the limiting member 85e is connected to the limiting groove of the mounting base 83.

[0059] Installing a limiting element 85e on the second bolt 85b and connecting it with the limiting groove of the mounting base 83 greatly enhances the stability and reliability of the adjustment of the auxiliary mechanism 85. The limiting element 85e and the limiting groove are tightly fitted, which can effectively prevent the second bolt 85b from being displaced during operation. When the height of the auxiliary roller 85d is adjusted according to the different conveyor belt operation requirements, the limiting element 85e can ensure that the second bolt 85b is kept in a fixed position, preventing the height of the auxiliary roller 85d from changing due to factors such as equipment vibration and changes in conveyor belt tension.

[0060] As a preferred option, such as Figure 3 As shown, a support rod 9 is provided on the extension shaft 6, and the support rod 9 is slidably installed in the inner hole of the extension column 4.

[0061] The support rod 9 on the extension shaft 6 and its sliding installation design with the inner hole of the extension column 4 greatly optimize the running performance and stability of the idler roller 5. This not only prevents the idler roller 5 from excessive displacement or deformation due to excessive force, thus extending the service life of the idler roller 5, but also ensures that the idler roller 5 always stays in the proper position.

[0062] As a preferred option, such as Figures 1 to 2 As shown, the mounting base 1 is provided with assembly holes;

[0063] The assembly holes provided on the mounting base 1 greatly facilitate the installation and maintenance of the belt conveyor idler roller adjustment device.

[0064] The belt conveyor idler roller adjustment device of this utility model can be installed, connected or set in a common mechanical way, and can be implemented as long as it can achieve its beneficial effect.

[0065] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
