Speed change device applied to rope twisting machine

The utility model provides a speed change device applied to a rope twisting machine, and belongs to the technical field of rope twisting equipment. The rope twisting machine solves the problem that the stability of a produced twisted rope is not high due to the fact that the rotating speed of a rotating disc cannot be well adjusted in the working process of an existing rope twisting machine. According to the speed change device applied to the rope twisting machine, the rope twisting machine comprises a base and a driving motor arranged on the base, the base is further provided with a rotating disc mechanism driven by the driving motor, the rotating disc mechanism is arranged on the base through a stand column, and the rotating disc mechanism is composed of a large rotating disc, a small rotating disc, a driving shaft and a transmission assembly. The small rotating disc is connected to the large rotating disc through a rotating shaft, a spindle blade used for machining is arranged on the small rotating disc, t
