The invention discloses a rubber regenerating on-line Mooney detection control device. The rubber regenerating on-line Mooney detection control device comprises a detection control device body, the detection control device body is provided with a detection cavity, a placing platform is fixedly installed on the inner wall of the bottom of the detection cavity, columns are welded to both sides of the top of the placing platform, mounting grooves are both formed in the sides, close to each other, of the two columns, driving motors are both fixedly installed on the inner walls of the sides, away from each other, of the two mounting grooves, connecting shafts are welded to output shafts of the driving motors, the ends, away from the driving motors, of the connecting shafts stretch into the detection cavity and are welded to fixed blocks, and the sides, close to each other, of the two fixed blocks are both provided with through grooves. The rubber regenerating on-line Mooney detection control device facilitates detection, by fixing rubber to be detected between two strong magnets and then driving the fixed blocks to rotate through the driving motors, the rubber to be detected can rotateand is conveniently detected, and the operation is simple.
