Detection device provided with rotary plates and used for detecting two end faces of roller

The utility model discloses a detection device provided with rotary plates and used for detecting two end faces of a roller. The detection device comprises a roller large-diameter end detection mechanism and a roller small-diameter end detection mechanism, wherein the large-diameter end detection mechanism is positioned above the small-diameter end detection mechanism. The detection device has the advantages as follows: the structure is simple, the detection is convenient, the working efficiency is high, and the labor force of workers is greatly reduced; a roller is conveyed through the rotary plate at the large-diameter end, the small-diameter end of the roller just faces outwards when the roller enters the rotary plate at the small-diameter end, the rotary plate at the large-diameter end can be utilized to change the direction of the roller, and both the large-diameter end and the large-diameter end of the roller can be detected in the same device, so that the detection effect is better and more stable.
