Description

Technical Field

[0001] This utility model relates to the field of idler roller technology, and in particular to an idler roller bracket. Background Technology

[0002] Conveyors require idlers to be installed below the conveyor belt during operation to support the belt and the material on it. These idlers are mounted on supports, which in turn attach them to the conveyor. Supports typically consist of a base and an arc-shaped frame. In existing technology, to facilitate idler installation and removal, a limiting groove is usually created on the support base to limit the installation shaft of the idler. During installation, the installation shaft is aligned with the limiting groove, and the idler and installation shaft fall into the groove under gravity. While this type of support is convenient to install, it is not convenient for adjusting the angle of the side idlers. Some existing technologies use arc-shaped frames to adjust the angle of the side idlers, but their complex adjustment structure makes disassembly and assembly difficult. Therefore, there is an urgent need for an idler support that is easy to disassemble and adjust the angle of the side idlers. Utility Model Content

Detailed Implementation

[0016] 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.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Reference Figure 1-2 This utility model provides a roller support, including a base 1, two support seats 2 fixedly connected to the base 1, a flat roller 3 detachably connected between the two support seats 2, and two support frames 4 fixedly connected to the base 1 corresponding to the support seats 2. A side roller 5 is disposed between the support frame 4 and the corresponding support seat 2. A control component for controlling the tilt angle of the side roller 5 is installed on the support frame 4; a connecting component for preventing the side roller 5 from separating from the support seat 2 is provided on the support frame 4. The support seats 2 support the flat roller 3 and the side roller 5, while the connecting component limits the side roller 5, preventing it from separating from the support seat 2. When the side roller 5 needs to be disassembled, only the position of the connecting component needs to be adjusted so that it no longer limits the side roller 5, allowing for disassembly. Furthermore, the control component of this application, in cooperation with the support frame 4, can adjust the angle of the side roller 5.

[0019] In a further optimized design, a first mounting shaft 6 is installed through the flat idler roller 3 along its axial direction. The first mounting shaft 6 rotatably engages with the flat idler roller 3. Strip plates 7 are fixedly connected to both ends of the first mounting shaft 6. The support base 2 has a sliding groove adapted to the first mounting shaft 6 and a strip groove adapted to the strip plate 7. The sliding groove and the strip groove are connected, and the strip plate 7 slides within the strip groove. Through the engagement of the strip plate 7 and the strip groove on the first mounting shaft 6, disassembly of the flat idler roller 3 can be completed simply by lifting the first mounting shaft 6 and the flat idler roller 3, making disassembly convenient and quick.

[0020] In a further optimized design, a second mounting shaft 8 is installed through the side idler roller 5 along its axial direction. A vertical groove is provided on the support base 2, and a mounting plate 9 is slidably connected within the vertical groove. The mounting plate 9 is vertically positioned, with its top end located outside the vertical groove. The top end of the mounting plate 9 is rotatably connected to one end of the second mounting shaft 8. The sliding engagement between the mounting plate and the vertical groove facilitates the assembly and disassembly of the side idler roller 5.

[0021] Further optimization of the scheme: the connecting component includes an arc-shaped seat 10, located at the end of the second mounting shaft 8 away from the support base 2. The end of the second mounting shaft 8 away from the support base 2 is threaded, and the second mounting shaft 8 passes through the arc-shaped seat 10 and is threadedly engaged with it. Each support frame 4 includes two parallel arc-shaped frames, spaced apart, with the second mounting shaft 8 located between the two arc-shaped frames. The arc-shaped seat 10 slides against the inner wall of the arc-shaped frame. Through the sliding and tight fit between the arc-shaped seat 10 and the inner wall of the arc-shaped frame, the second mounting shaft 8 cannot move in the axial direction. Furthermore, since the side roller 5 and the second mounting shaft 8 are inclined, the second mounting shaft 8 will inevitably deviate in the axial direction during the ascent of the mounting plate 9 away from the support base 2 to ensure the proper removal of the mounting plate 9. Therefore, the arc-shaped plate 10 can limit the mounting plate 9, stabilizing it on the support base 2 and ensuring the stability of the side roller 5.

[0022] In a further optimized design, a number of ball bearings 11 are rotatably connected to the side of the arc-shaped seat 10 near the arc-shaped frame, and the ball bearings 11 are positioned in contact with the arc-shaped frame. The ball bearings 11 are used to reduce the friction between the arc-shaped seat 10 and the arc-shaped frame.

[0023] Further optimizing the design, the control component includes an arc-shaped toothed plate 12 fixedly connected to the arc-shaped frame. The arc-shaped toothed plate 12 is located on the side of the arc-shaped frame away from the side roller 5. A limit block 13 is slidably connected to the second mounting shaft 8 along its axial direction. The limit block 13 has teeth that fit with the arc-shaped toothed plate 12, and the limit block 13 cooperates with the arc-shaped toothed plate 12. A control nut 14 is threadedly connected to the second mounting shaft 8, and the control nut 14 abuts against the limit block 13. By abutting against the limit block 13, the limit block 13 and the arc-shaped toothed plate 12 are tightly fitted, thereby limiting the second mounting shaft 8 and stabilizing it at a specified angle.

[0024] In a further optimized design, a limiting groove 15 is formed on the side wall of the second mounting shaft 8 along its axial direction. A through hole is formed in the middle of the limiting block 13. The second mounting shaft 8 passes through the through hole and is spaced apart from the inner wall of the through hole. A connecting block 16 is fixedly connected to the inner wall of the through hole and the limiting groove 15, and the connecting block 16 slides within the limiting groove 15. Through the cooperation between the connecting block 16 and the limiting groove 15, it is ensured that the limiting block 13 can only move along the axial direction of the second mounting shaft 8 and will not come into contact with the threads.

[0025] The working process of this utility model is as follows: When the angle of the side roller 5 needs to be adjusted, simply rotate the control nut 14 so that the control nut 14 no longer limits the limit block 13, and the limit block 13 is no longer tightly fitted with the arc-shaped toothed plate 12. This allows the angle of the second mounting shaft 8 to be adjusted. After adjustment, rotate the control nut 14, and the control nut 14 presses the limit block 13. Through the cooperation of the teeth and the arc-shaped toothed plate 12, the second mounting shaft 8 is limited and stabilized at the specified angle. When the flat roller 3 and the side roller 5 need to be disassembled and replaced, simply lift the flat roller 3 upwards to complete the disassembly. Then rotate the arc-shaped seat 10 so that the arc-shaped seat 10 is no longer tightly fitted with the support frame 4. Then, simply lift the mounting plate 9 from the support seat 2 and remove it. If necessary, the control nut 14 can be loosened first to prevent the limit block 13 from interfering with its normal removal.
