Lower roller changing device of conveyor

Abstract

The utility model relates to the technical field of roller changing devices, and discloses a lower roller changing device of a conveyor, which comprises two mounting frames which are symmetrically distributed, a rotating rolling roller is arranged between the two mounting frames, a supporting structure is arranged below supporting legs, a fixed electric sliding table is arranged in the center of the supporting structure, and the electric sliding table is arranged on the lower portion of the supporting structure. A sliding electric sliding block is arranged above the electric sliding table, a telescopic rod is fixedly installed at the output end of the electric sliding block, a fixing plate is fixedly installed at the output end of the telescopic rod, and a spring is fixedly installed on the bottom side of the fixing plate. According to the rolling roller replacing device, a new rolling roller is placed on the clamping structure after the rolling roller is taken out, the rolling roller is placed in the first movable cavity along with downward movement of the fixing plate, the movable plate drives the extrusion structure to move downwards, the extrusion structure relieves constraint on the limiting structure, the limiting structure plays a role again, and therefore the rolling roller can be replaced conveniently; therefore, workers can conveniently replace the rollers.
