The utility model relates to an untwisting device of glass fiber yarn balls. At present, most of production lines or test lines carry out test by adopting an externally-untwisting device or in a non-untwisting manner, the externally untwisting method is mainly characterized by hanging a single yarn ball on a rotary bearing, and the method is high in labor cost and slow in production speed, and greatly affects the increasing of production efficiency. The untwisting device of the glass fiber yarn balls provided by the utility model comprises a frame, a chuck, a driving device, a frequency converter and a controller, wherein the driving device is fixed on the frame, the chuck is provided with a rotary shaft penetrating the table board of the frame, the rotary shaft is arranged in the vertical direction, the frequency converter is used for controlling rotation speed of the driving device, the controller controls the frequency converter through outputting control signals, the frequency converter is connected with the driving device, and the controller is connected with the frequency converter. The untwisting device has the advantages of simple structure, reasonable design, high untwisting efficiency, small unwinding tension, simple production process and stable product quality.
