[0003] For example, Chinese patent CN210312145U proposes an automatic tensioning device for extended belt conveyors. This device adds a counterweight beneath the tensioning roller, automatically adjusting the tensioning force based on the weight's gravity. However, this design, with its indefinite position, makes the counterweight prone to wobbling and poorly stabilized, impacting the overall belt conveyor's service life. Utility Model Content

[0012] Furthermore, a buffer mechanism is provided between the two columns, and the buffer mechanism is located directly below the counterweight mechanism.

[0013] Furthermore, the buffer mechanism includes a base, a buffer, a buffer plate and a rubber pad; the base is arranged between two columns and a buffer plate is connected to it through a buffer, and a layer of rubber pad is provided on the buffer plate. The rubber pad is located directly below the buffer mechanism so that the buffer mechanism can flexibly contact with the rubber pad after falling.

[0014] Furthermore, the buffer mechanism includes an internal threaded seat and a polyurethane bumper; the internal threaded seat is arranged between the two columns and the polyurethane bumper is threadedly connected thereto, and the polyurethane bumper is located directly below the buffer mechanism so that the buffer mechanism is in flexible contact with the polyurethane bumper after falling, and at the same time, the polyurethane bumper buffers the buffer mechanism.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] In the utility model, the tension of the conveyor belt can be adaptively adjusted, and since the upright column is provided to guide and limit the counterweight mechanism, the stability of the counterweight mechanism operation is improved; and when the conveyor belt is damaged due to problems such as wear or pulling, the damaged part can be cut off, the length of the conveyor belt is shortened, and then the conveyor belt can be glued together for continued use, without replacing the entire conveyor belt, thereby achieving the purpose of reducing the cost of replacing the conveyor belt, and having high use value.
