A self-adaptive centering roller

Abstract

The utility model discloses an adaptive self-aligning roller comprising a U-shaped bracket, a roller, a roller frame, an adjusting bolt, a positioning plate, a guide wheel and an arc-shaped support plate. The roller frame has a rotating platform, an extension arm and a connecting plate. The guide wheels are fixedly connected to the two sides of the bottom of the U-shaped bracket, and inclined extension arms are symmetrically arranged on the two sides of the rotating platform. The outer ends of the extension arms are fixedly connected to the connecting plates, and the positioning plates are installed and fixed by bolts and the connecting plates. The rollers are rotatably connected between the rotating platform and the positioning plates on both sides, and the arc-shaped support plates are fixedly connected to the positions of the guide wheels at the bottoms of the extension arms on both sides. The positioning plates are fixed to the positions of the waist-shaped holes by adjusting the positioning plates, thereby changing the inclination angle of the rollers driven by the positioning plates, so that the rollers can be more fully in contact with the belt during deviation correction. When the deflection angle of the supporting roller is adjusted for deviation correction, the forces exerted on the rollers on both sides are shared by the arc-shaped support plates and the guide wheels on both sides, thereby reducing the bending moment exerted on the central rotating shaft.

Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor rollers, in particular to a self-adaptive self-aligning roller. Background Art

[0002] During the transportation process of the belt conveyor, the belt often deviates due to uneven materials on the belt, which in turn causes friction between the belt edge and the frame, resulting in damage to the belt edge or wear of the frame. In severe cases, it may also cause the belt to catch fire due to friction. Therefore, when the belt deviates during the belt transportation process, the self-aligning roller bracket needs to be adjusted and corrected. The existing self-aligning rollers cannot adjust the angle between the rollers on both sides, which makes the rollers unable to better contact with the belts, and the existing self-aligning rollers are only supported by the central shaft. When the self-aligning rollers are corrected, the central shaft will be subjected to a large bending moment force. After long-term load operation, the central shaft is also easily deformed, and in severe cases, it may even break. Therefore, an adaptive self-aligning roller is designed to solve the above problems.

[0005] Preferably, the axis angle between the rollers on both sides is a, wherein 120°≥a≥180°;

[0007] Preferably, the end face of the connecting plate also has a waist-shaped hole, which is used to adjust the fixing position of the positioning plate; by adjusting the position of the positioning plate fixed in the waist-shaped hole, the inclination angle of the roller driven by the positioning plate is changed, so that the roller can be in more complete contact with the belt during correction, so as to achieve a better correction effect.

[0008] The beneficial effects of the utility model are: 1. By adjusting the position of the positioning plate fixed in the waist-shaped hole, the inclination angle of the roller driven by the positioning plate is changed, so that the roller can be in more complete contact with the belt during deviation correction, so as to achieve a better deviation correction effect; 2.
