[0034] A fixing frame 3 is rotatably mounted on one end of the support rod 6;

[0035] Cleaning pieces (2, 5) are mounted on the fixing frame 3, and the free ends of the cleaning pieces (2, 5) abut against the outer peripheral wall of the belt conveyor roller 1;

[0036] The counterweight assembly is hung on the other end of the support rod 6, and the counterweight weight of the counterweight assembly is adjusted, and the pressure of the cleaning sheet (2, 5) on the outer peripheral wall of the belt conveyor roller 1 is adjusted through the lever action of the support rod 6.

[0037] In the present embodiment, a belt conveyor roller cleaning device is provided, wherein a fixed frame 3 is rotatably mounted on one end of the support rod 6, so that during the cleaning process, the cleaning blades (2, 5) can always maintain contact with the outer peripheral wall of the belt conveyor roller 1, thereby ensuring a cleaning effect. Moreover, when multiple cleaning blades are mounted on the fixed frame 3, it is possible to ensure that the forces exerted by the multiple cleaning blades on the belt conveyor roller 1 remain horizontal. In addition, by adjusting the counterweight weight of the counterweight assembly, the present embodiment adjusts the pressure exerted by the cleaning blades (2, 5) on the outer peripheral wall of the belt conveyor roller 1 through the lever action of the support rod 6, thereby ensuring that an optimal cleaning effect is achieved.

[0038] As an optional embodiment of this embodiment, the cleaning sheet of this embodiment includes an upper cleaning sheet 2 mounted on the upper end of the fixing frame 3 and a lower cleaning sheet 5 mounted on the lower end of the fixing frame 3. The upper cleaning sheet 2 and the lower cleaning sheet 5 are symmetrically arranged in a vertical direction. In this way, the upper cleaning sheet 2 and the lower cleaning sheet 5 cooperate to achieve better cleaning.

[0039] Further, the upper cleaning sheet 2 and the lower cleaning sheet 5 described in the present embodiment are respectively arranged along the radial direction of the belt conveyor roller 1. Like this, it is possible to ensure that the upper cleaning sheet 2 and the lower cleaning sheet 5 achieve the best cleaning effect.

[0040] As an optional implementation of this embodiment, see Figure 4 As shown, the fixed frame 3 of this embodiment includes a fixed block 301, an upper rotating block 302 and a lower rotating block 303. The upper rotating block 302 is rotatably mounted on the upper end of the fixed block 301, and the lower rotating block 303 is rotatably mounted on the lower end of the fixed block 301. The upper cleaning sheet 2 is mounted on the upper rotating block 302, and the lower cleaning sheet 5 is mounted on the lower rotating block 303. By adjusting the angle of the upper rotating block 302 relative to the fixed block 301, the upper cleaning sheet 2 is arranged along the radial direction of the belt conveyor roller 1. By adjusting the angle of the lower rotating block 303 relative to the fixed block 301, the lower cleaning sheet 5 is arranged along the radial direction of the belt conveyor roller 1.
