A column 15 is fixedly installed integrally below the fixed frame 1.

[0025] See also Figure 2 and Figure 3 , an anti-static conveyor belt structure, including a limit slide 17, which is opened on both sides of the inner wall of the active cavity 8, and a limit slider 16 is movably installed inside the limit slide 17; the shape and size of the limit slider 16 partially coincide with the shape and size of the inside of the limit slide 17, and the limit slider 16 is fixedly connected to the lifting frame 4, and the lifting frame 4 is movably connected to the active cavity 8 through the limit slider 16 and the limit slide 17; a first connecting bearing 6 is installed in the middle part of the interior of the lifting frame 4, and an adjusting bolt 5 is passed through the interior of the first connecting bearing 6; the adjusting bolt 5 is movably connected to the lifting frame 4 through the first connecting bearing 6, and the adjusting bolt 5 passes through the inner wall of the fixed frame 1, and the adjusting bolt 5 is threadedly connected to the fixed frame 1; by setting up an adjustable lifting frame 4, the second metal conductive rod 7 is driven to adjust up and down, so as to adjust the distance between the second metal conductive rod 7 and the first metal conductive rod 3, so as to facilitate the use of conveyor belt bodies 2 of different thicknesses.

[0026] Working principle: When using this anti-static conveyor belt structure, first tighten the adjusting bolt 5 to push the lifting frame 4 to move downward inside the movable cavity 8, thereby driving the second metal conductive rod 7 to move downward and cooperate with the first metal conductive rod 3 to clamp the conveyor belt body 2. Then, when the conveyor belt body 2 is working, the transmission roller drives the conveyor belt body 2 to transmit. Since the column 15 is installed on the ground or the conveyor device bracket, the fixed frame 1 is stationary. The transmitting conveyor belt body 2 drives the first metal conductive rod 3 and the second metal conductive rod 7 to rotate, reducing the friction between the conveyor belt body 2 and the conveyor belt body 2. Secondly, during the transmission process, the conveyor belt body 2 rubs against the objects or the transmission roller to generate static electricity.
