Description

Technical Field

[0001] This utility model relates to the field of idler rollers, specifically to an anti-deviation idler roller. Background Technology

[0002] Idler rollers are important support mechanisms in belt conveyors. They generally include horizontal rollers and inclined rollers arranged on both sides of the horizontal rollers. Idler rollers convert the sliding friction between the belt and the frame into rolling friction through their own rolling motion, which greatly reduces running resistance. To prevent the belt from shifting on the idler rollers, existing idler rollers generally have anti-deviation structures. For example, Chinese patent CN222347917U provides an idler roller with an anti-deviation structure, including a base plate, side frames fixedly connected to both sides of the top of the base plate, and end frames fixedly connected to both ends of the base plate. A roller shaft 1 is engaged between the two side frames and the end frame, and a roller shaft 2 is engaged between the side frame and the end frame. Rollers are rotatably connected to the surfaces of roller shaft 1 and roller shaft 2 via bearing 1. Inclined seats are fixedly connected to both sides of the back of the base plate. A threaded rod is rotatably connected to the inner wall of the inclined seat via bearing 2. A stroke block is threadedly connected to the surface of the threaded rod, and a support rod is fixedly connected to the top of the stroke block. In the above-mentioned prior art anti-deviation structure for idler rollers, the rollers of the limiting belt are arranged vertically, and the transmission direction on both sides of the belt is not perpendicular to the rotation axis direction of the limiting roller, resulting in greater wear on both sides of the belt. Utility Model Content

[0003] The purpose of this invention is to provide an anti-deviation idler roller, which solves the problem in the existing anti-deviation structure of idlers where the rollers of the limiting belt are set vertically, and the transmission directions on both sides of the belt are not perpendicular to the rotation axis of the limiting rollers, resulting in greater wear on both sides of the belt.

[0004] To achieve the above objectives, this utility model provides an anti-deviation type idler roller, which includes a base body, a support in the middle of the base body, a horizontal roller on the support, and inclined rollers on both sides of the support. A limiting roller is provided in the base near the inclined roller. The limiting roller is rotatably mounted on the shaft, and the axis of the limiting roller is perpendicular to the axis of the inclined roller. The base is provided with an adjustment structure, and the shaft is movably mounted on the adjustment structure, so that the shaft can drive the limiting roller to move along the axial direction of the inclined roller.

[0005] Preferably, a slide bar is connected to the shaft, and the slide bar is arranged along the axial direction of the inclined roller; The adjustment structure includes a slide rail seat disposed on the base, and the slide bar is slidably disposed within the slide rail seat.

[0006] Preferably, a scale is fixed on the surface of the slider, and a pointer that cooperates with the scale is provided at the end of the slide rail seat.

[0007] Preferably, the adjustment structure further includes a mounting base that is locked onto the base by a screw assembly, and the slide rail is fixed on the mounting base.

[0008] Preferably, locking screws are screwed onto both sides of the slide rail seat, and the ends of the locking screws extend into the slide rail seat and fit against the slide bar.

[0009] Beneficial Effects: This utility model provides an anti-deviation idler roller, which includes a base, a support in the middle of the base, a horizontal roller on the support, and inclined rollers on both sides of the support. A limiting roller is provided in the base near the inclined rollers, and the limiting roller is rotatably mounted on a shaft, with its axis perpendicular to the axis of the inclined roller. An adjustment structure is provided on the base, and the shaft is movably mounted on the adjustment structure, allowing the shaft to drive the limiting roller to move along the axis of the inclined roller. In this structure, the axes of the limiting roller and the inclined roller are perpendicular to each other, ensuring that the transmission direction on both sides of the belt is perpendicular to the axis of the limiting roller, effectively reducing wear on both sides of the belt. Simultaneously, the width of the limiting rollers on both sides can be adjusted along the axis of the inclined roller to meet the needs of belts of different widths.
