The new type of adjusting roller(self-aligning roller), including the conveyor belt, the conveyor belt and the roller contact, it has the offset roller set and the polarization adjustment linkage two parts, the deviation of the linkage part is: two on the conveyor belt. The end is respectively provided with a vertical roller, and the vertical roller is respectively connected with the vertical rod through the first vertical rod connector, and the second vertical rod connector is fixed on the vertical rod and the horizontal rod is connected, and the horizontal rod is connected with the flat pull rod through the precision adjuster, and is flat The drawbar is welded to the set of offset rollers.

This new type can solve the problem of poor polarization adjustment, complicated structure and high failure rate. A rib roller for use in a self-aligning roller set with good wear resistance, high impact resistance and low noise. The new self-aligning roller for the roller set is realized by a technical solution, including a shaft, the outer peripheral surface of the shaft is adjacent to the inner peripheral surface of the ultra-high molecular polyethylene roll skin, and the upper and lower end faces of the roll skin are respectively disposed on the circumference.

The lower groove is disposed in the lower groove through the shaft through the retaining ring, and the retaining ring of the upper shaft is located outside the shaft end and disposed in the upper groove, and the outer cover of the upper end surface of the shaft is provided with a stuff cover.

The novel rectifying device for the belt conveyor is equipped with a self-aligning roller set, which not only has reliable operation but also greatly reduces noise, and has almost no damage to the edge of the conveyor belt, thereby improving the service life of the tape， then to improve the service life of the roller bearings.
