[0033] like Figures 1 to 6 As shown, this embodiment provides a roller adjustment device for mounting a roller 10 on a frame 20. The frame 20 has a waist-shaped hole 201. The roller adjustment device includes a positioning member 1, an adjusting member 2, and a connecting member 3. The positioning member 1 and the adjusting member 2 are respectively disposed on both sides of the frame 20. The positioning member 1 is used to connect with the roller 10. One end of the connecting member 3 abuts against the adjusting member 2, and the other end of the connecting member 3 passes through the adjusting member 2 and the waist-shaped hole 201 in sequence and is threadedly connected to the positioning member 1. The connecting member 3 is slidably disposed in the waist-shaped hole 201.

[0034] By opening a waist-shaped hole 201 on the frame 20, positioning component 1 and adjusting component 2 are respectively set on both sides of the frame 20. The positioning component 1 is connected to the idler roller 10, and the positioning component 1 and adjusting component 2 are fixed on the frame 20 by the connecting component 3. When it is necessary to adjust the position of the idler roller 10, simply loosen the connecting component 3 and adjust the position of the adjusting component 2 from the outside of the frame 20, thereby changing the position of the connecting component 3, positioning component 1 and idler roller 10, which effectively reduces the difficulty of operation and improves maintenance efficiency. After adjusting to the required position, tightening the connecting component 3 completes the position adjustment of the idler roller 10.

[0035] Specifically, the idler roller 10 includes a main roller body, a shaft head 101, and a bearing. The main roller body is rotatably connected to the shaft head 101 via the bearing. The main roller body is used to support the conveyor belt of the belt conveyor. The main roller body is connected to the frame 20 of the belt conveyor via the shaft head 101.

[0036] It is understood that both ends of the idler roller 10 are connected to the frame 20 via idler roller adjustment devices (i.e., positioning component 1, adjustment component 2, and connecting component 3). If the idler roller 10 has only one shaft head 101, which passes through the main roller body and has its end outside the main roller body, then both ends of the shaft head 101 are mounted on the frame 20 via the idler roller adjustment device. If the idler roller 10 has two shaft heads 101, both ends of the main roller body are rotatably connected to one shaft head 101 via bearings, and each shaft head 101 is connected to the frame 20 via the idler roller adjustment device. When the shaft head 101 is connected to the frame 20, and when the main roller body supports the conveyor belt of the belt conveyor, the operation of the conveyor belt drives the main roller body to rotate relative to the shaft head 101 through surface friction.

[0037] See Figure 2 In this embodiment, the shaft head 101 of the idler roller 10 extends along the X direction, and the frame 20 is provided with a frame main plate extending along the Z direction. The frame main plate is provided with an oblong hole 201, the length direction of which is the Y direction. The positioning member 1 and the adjusting member 2 are respectively disposed on both sides of the frame main plate along the X direction. The shaft head 101 and the positioning member 1 are both located inside the frame main plate, and the adjusting member 2 is located outside the frame main plate. The connecting member 3 is a fixing bolt. By adjusting the adjusting member 2 outside the frame main plate, the position of the idler roller 10 can be adjusted. Compared with the existing method of adjusting the position of the idler roller 10 by operating in the space inside the frame main plate, the space outside the frame main plate is larger, making the adjustment operation unrestricted by space and more convenient.

[0038] In this embodiment, the positioning member 1 engages with the shaft head 101 of the idler roller 10. Specifically, the positioning member 1 is provided with a limiting groove 11, which is used for inserting the shaft head 101 of the idler roller 10. By providing the limiting groove 11 on the positioning member 1, the shaft head 101 can be inserted into the limiting groove 11, which is convenient for disassembly and assembly, and the limiting groove 11 can be used to restrict the position of the shaft head 101.

[0039] To facilitate the insertion of the shaft head 101, the limiting groove 11 forms an opening on one side of the positioning member 1, allowing the shaft head 101 to be inserted into the limiting groove 11 through the opening. In this embodiment, the limiting groove 11 and the top surface of the positioning member 1 form an opening; by providing a limiting groove 11 with a top opening on the positioning member 1, it can be ensured that the positioning member 1 supports the shaft head 101, and the shaft head 101 can also be inserted into the limiting groove 11 through the opening during installation, which facilitates the disassembly and maintenance of the shaft head 101.

[0040] Specifically, the limiting groove 11 has a bottom wall 111 and two oppositely arranged side walls 112. The side walls 112 are connected to the bottom wall 111. The bottom wall 111 supports the shaft head 101, and the side walls 112 limit the shaft head 101. By using the bottom wall 111 to support the shaft head 101 and the side walls 112 to limit the shaft head 101 from both sides, the relative position of the shaft head 101 and the limiting groove 11 is fixed.

[0041] In this embodiment, the positioning member 1 is block-shaped, and the limiting groove 11 is located in the middle of the positioning member 1. The shape of the limiting groove 11 matches the shape of the end of the shaft head 101. The limiting groove 11 is a U-shaped groove. The bottom wall 111 of the groove is arc-shaped, and the two side walls 112 of the groove are flat. The limiting groove 11 penetrates the positioning member 1 along the X direction. By setting the limiting groove 11 that penetrates along the X direction, the length of the shaft head 101 inserted into the limiting groove 11 can be adjusted according to the actual situation.

[0042] Furthermore, the adjusting member 2 includes a main board portion 21 and an auxiliary plate portion 22 connected to the main board portion 21. The main board portion 21 is used to contact the frame 20, and the connecting member 3 passes through the main board portion 21. The auxiliary plate portion 22 extends in a direction away from the frame 20 and forms a preset angle with the main board portion 21. By providing the adjusting member 2 with the main board portion 21 and the auxiliary plate portion 22, under the action of the connecting member 3, the main board portion 21 contacts and is fixed to the outside of the frame 20. Since the auxiliary plate portion 22 extends in a direction away from the frame 20 and forms a preset angle with the main board portion 21, the adjusting member 2 can be moved by holding the auxiliary plate portion 22, thereby achieving the desired position and facilitating operation.

[0043] The preset included angle ranges from 100 degrees to 125 degrees. In this embodiment, the motherboard portion 21 abuts against the outer surface of the frame 20; the preset included angle is 105 degrees.

[0044] Optionally, two auxiliary board portions 22 are provided, with one auxiliary board portion 22 connected to each end of the main board portion 21. In this embodiment, the two auxiliary board portions 22 are symmetrically arranged with respect to the main board portion 21.

[0045] Optionally, the length of the main board portion 21 is less than the length of the oblong hole 201. In this embodiment, the length direction of the main board portion 21 is the Y direction. By setting the length of the main board portion 21 in the Y direction to be less than the length of the oblong hole 201, it is easier for the operator to observe and judge the relative position of the adjusting member 2 and the frame 20.

[0046] Furthermore, at least two connecting pieces 3 are spaced apart; the connection between the positioning piece 1 and the idler roller 10 is located between two adjacent connecting pieces 3. By spaced apart two connecting pieces 3 and connecting them at different positions, it helps to ensure the stability of the installation of the positioning piece 1 and the adjusting piece 2; by placing the connection between the positioning piece 1 and the idler roller 10 between two adjacent connecting pieces 3, the force at the connection point is more even, preventing the idler roller 10 from shifting due to unstable fixing, thus affecting the normal operation of the belt conveyor.

[0047] Correspondingly, the positioning component 1 is provided with two threaded holes 12, and the limiting groove 11 is located between the two threaded holes 12. The threaded holes 12 penetrate the positioning component 1 along the X direction. The main plate portion 21 of the adjusting component 2 is provided with two through holes 211, which correspond one-to-one with the threaded holes 12. One end of the connecting component 3 abuts against the main plate portion 21, and the other end passes through the through hole 211 and the oblong hole 201 in sequence and is threadedly engaged with the threaded hole 12. Before the connecting component 3 is tightened, the connecting component 3 can slide in the oblong hole 201 along the Y direction. After the connecting component 3 is tightened, both the positioning component 1 and the adjusting component 2 abut against the frame 20 and clamp the frame 20, thereby fixing them on the frame 20.

[0048] In this embodiment, two connectors 3 are arranged side by side with a gap along the Y direction. Correspondingly, two threaded holes 12 are arranged side by side with a gap along the Y direction, and two through holes 211 are also arranged side by side with a gap along the Y direction. The distance between the two connectors 3 is equal to the distance between the two threaded holes 12 and the distance between the two through holes 211. The distance between the two connectors 3 is less than the length of the oblong hole 201, and the distance between the two connectors 3 is equal to half the length of the oblong hole 201 in the Y direction.

[0049] This embodiment also provides a belt conveyor, which includes a conveyor belt, idlers 10, a frame 20, and an idler adjustment device. The idlers 10 support the conveyor belt. The conveyor belt is a belt. The idlers 10 of the belt conveyor are mounted on the frame 20, supporting the lower layer of the conveyor belt. The idlers 10 are mounted on the frame 20 using the idler adjustment device, making it convenient to adjust their position. Adjusting the position of the idlers 10 also allows for adjustment of the conveyor belt position, improving conveyor belt misalignment and increasing replacement and maintenance efficiency.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
