Feeding anti-blocking device based on conical bearing assembly roller

The utility model discloses a feeding anti-blocking device based on conical bearing assembly rollers, relates to the technical field of bearing assembly feeding devices, and solves the problem that a mechanical arm is easy to grab a plurality of retainers at one time when grabbing the retainers of the rollers due to the fact that an existing feeding device is not provided with an anti-blocking structure. The anti-blocking device comprises an anti-blocking assembly, and an installation shell is fixedly installed on the side face of the top of a supporting stand column. The anti-blocking assembly of the device can avoid the phenomenon that a plurality of retainers are grabbed at a time when a mechanical clamping arm clamps the retainers for assembly, use is stable, it is ensured that the retainers and rollers are assembled stably, and the yield is greatly increased; the material blocking piece can be driven by the control air cylinder to move inwards to limit and fix the retainer at the bottom through the mater
