[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] First embodiment:

[0039] For a variable tilt angle self-aligning idler assembly, please refer to [link / reference]. Figure 1-5 It includes a support 1, and a straight roller 2 that can be adjusted vertically is installed in the middle of the support 1. Specifically, the straight roller 2 uses a lifting mechanism to adjust its height in the vertical direction.

[0040] It also includes a mounting plate 6, on both sides of which a connecting frame 11 is fixedly connected. A diagonal brace 12 is fixedly connected to the bottom end of the connecting frame 11, and a first adjusting rod 13 is connected to the top end. An insert plate 1301 is fixedly connected to the end of the first adjusting rod 13, and a conical roller 3 is rotatably connected between the insert plate 1301 and the diagonal brace 12.

[0041] Specifically, the first adjusting rod 13 is a screw that passes through the connecting frame 11. Nuts are threaded to both ends of the rod at the position where it passes through the connecting frame 11. When you want the first adjusting rod 13 to extend diagonally upward, first rotate the lower nut to move it away from the connecting frame 11 at a suitable distance, then push the first adjusting rod 13 diagonally upward, and then tighten the upper nut to achieve the extension and retraction adjustment of the first adjusting rod 13.

[0042] It also includes an adjusting bracket 5, which is connected to the end of the telescopic frame 4. The telescopic frame 4 can adjust the telescopic amount along the length of the support 1. Specifically, the end of the telescopic frame 4 facing the support 1 is slidably connected to the support 1, and the ends of the support 1 are provided with fixing screws for fixing the extension of the telescopic frame 4. When the fixing screws are tightened, the telescopic frame 4 cannot extend or retract. The adjusting bracket 5 can adjust the height along the vertical direction of the telescopic frame 4, and its bottom end is fixedly connected to the belt conveyor.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 1-4A mounting plate 6 is fixedly connected to the middle of the bracket 1. Vertical plates 7 are fixedly connected to both ends of the mounting plate 6. Lifting plates 8 are slidably connected to the vertical plates 7 along the vertical direction. A crossbeam 9 is fixedly connected to the middle of the lifting plates 8. Straight rollers 2 are rotatably connected between the lifting plates 8 parallel to the crossbeam 9. Two parallel straight rollers 2 are connected by rotating the lifting plates 8.

[0044] Specifically, a lifting mechanism is provided between the middle of the crossbeam 9 and the mounting plate 6. The lifting structure is a telescopic column 10, which can be an electric push rod, a hydraulic rod, etc. In this embodiment, an electric push rod is used, which can conveniently control the extension and retraction of the lifting mechanism. The height of the straight roller 2 is controlled by the lifting mechanism. The top of the straight roller 2 is at the same height as the bottom of the position where the conical roller 3 contacts the conveyor belt, ensuring that the bottom surface of the conveyor belt is flat, which is conducive to the stable operation of the conveyor belt.

[0045] Furthermore, the vertical plate 7 is fixedly connected to the guide rod 15 in the vertical direction, and the lifting plate 8 is provided with a guide groove 16 on the side facing the guide rod 15 to cooperate with the guide rod 15, so as to ensure the smooth lifting of the lifting plate 8.

[0046] Second embodiment:

[0047] For a variable tilt angle self-aligning idler assembly, please refer to [link / reference]. Figure 1-5 Based on the first embodiment, the difference from the first embodiment is that the end of the telescopic frame 4 away from the support 1 is fixedly connected to the connector 401. Specifically, the adjusting support 5 is provided with a sliding groove for the connector 401 to slide in the vertical direction. The connector 401 passes through and is connected to the second adjusting rod 14 in the vertical direction. The second adjusting rod 14 also passes through the adjusting support 5 upward. The height of the telescopic frame 4 can be controlled by the second adjusting rod 14.

[0048] Specifically, the adjusting bracket 5 has a vertical waist hole facing the telescopic frame 4, and the telescopic frame 4 and the adjusting bracket 5 are connected by bolts passing through the waist hole to ensure a stable connection between the telescopic frame 4 and the adjusting bracket 5.

[0049] For further details, please refer to [link / reference]. Figure 1-4 The two ends of the bracket 1 are fixedly connected with reinforcing rods, which effectively strengthens the structural strength of the bracket 1. The bottom end of the cone roller 3 is a tapered shaft 301 and the top end is a straight shaft 302, which ensures that the cone roller 3 can rotate stably after the tilt angle is adjusted. The inclined support frame 12 and the insert plate 1301 are respectively provided with notches for matching the tapered shaft 301 and the straight shaft 302, which facilitates the assembly and disassembly of the straight roller 2 and the cone roller 3.

[0050] In practical operation, this invention allows for the following: rotating the nut on the first adjusting rod 13 controls the extension and retraction of the first adjusting rod 13, thereby adjusting the inclination angle of the conical roller 3 and adaptively correcting the conveyor belt. Simultaneously, the lifting mechanism extends and retracts to control the height of the lifting plate 8, ensuring that the top of the straight roller 2 remains flush with the bottom of the position where the conical roller 3 contacts the conveyor belt, thus guaranteeing stable support for the conveyor belt. Furthermore, when it is necessary to adjust the balance of the support 1, rotating the bolt on the second adjusting rod 14 controls the height of the telescopic frame 4, thereby enabling the adjustment of the vertical position of the correction roller group and the belt conveyor frame according to the working parameters.
