Referring to fig. 1-3, a flexible idler comprises:
the carrier roller 1 comprises a flexible shaft 10, a protective layer 11 sleeved on the flexible shaft 10, a plurality of rubber rollers 12 uniformly arranged along the length direction of the flexible shaft 10, and a plurality of deformation springs 13 connecting every two adjacent rubber rollers 12, wherein the plurality of deformation springs 13 are uniformly arranged along the circumferential direction of the rubber rollers 12;
and a hanging roller seat 2 movably connected with the end part of the flexible shaft 10.
The flexible carrier roller provided by the utility model divides the rubber rollers into a plurality of rubber rollers, and the rubber rollers are connected through the deformation springs, so that the rubber rollers act along the normal direction of the flexible carrier roller 1 when acting along the stress of the belt, the acting force in the tangential direction is reduced, and the deformation of the flexible carrier roller is smoother; meanwhile, due to the restoring acting force of the deformation spring, the flexible carrier roller can automatically restore to be approximately straight when not being acted by the acting force.
Specifically, the roller hanging seat 2 comprises a roller seat outer sleeve 20, a roller seat inner sleeve 21, a shaft end 22 and a bearing assembly 23, wherein the roller seat outer sleeve 20 is hinged to a belt conveyor support, the roller seat inner sleeve 21 is fixedly connected with the roller seat outer sleeve 20, the shaft end 22 and the roller seat inner sleeve 21 form a movable cavity 24, the shaft end 22 is coaxially fixed at the end part of the flexible shaft 10, and the shaft end 22 extends into the movable cavity 24 and is movably connected with the roller seat inner sleeve 21 through the bearing assembly 23. Therefore, when the whole flexible carrier roller is stressed, the flexible shaft 10 bends downwards and can drive the shaft end 22 to slide in the movable cavity 24, and meanwhile, the roller seat outer sleeve 20 is hinged to the bracket of the belt conveyor, so that the flexible carrier roller is convenient to deform and the stress is reduced.
The bearing assembly 23 includes a bearing 230, an end cover 231 and a buffer spring 232, an outer ring of the bearing 230 is pressed against an inner wall of the movable cavity 24 in a sliding manner, an inner ring of the bearing 231 is coaxially fixed on the shaft end 22, the end cover 231 covers one end of the bearing 230 far away from the flexible shaft 10 and is coaxially fixed with the outer ring of the bearing 231, and one side of the end cover 231, which is back to the bearing 230, is flexibly connected with the bottom end of the movable cavity 24 through the buffer spring 232.
