The invention provides a cluster wheel rotating device. The cluster wheel rotating device comprises a supporting bracket, an air cylinder, a transmission frame, one-way rotating assemblies and clusterwheels, the air cylinder is fixed on the supporting bracket, a first end of the transmission frame is fixedly connected with an output end of the air cylinder, a second end of the transmission frameis in transmission connection with the one-way rotating assemblies, the one-way rotating assemblies are in transmission connection with the cluster wheels, and the one-way rotating assemblies are in transmission connection with the supporting bracket. According to the cluster wheel rotating device, the automatic timing, orientation and quantitative rotation of the cluster wheels are achieved through the one-way rotating assemblies, so that the artificial labor is fully liberated, the labor intensity is reduced, the automation of the rotation of the cluster wheels is achieved, the one-way rotation is less error prone, the product quality is improved, and the effective utilization rate of the cluster wheels is improved; the economic loss of production caused by improper manual operation or wear of the cluster wheels is effectively reduced.
