Carbon fiber unwinding system

The utility model provides a carbon fiber unwinding system. The carbon fiber unwinding system comprises an unwinding device and a position adjusting device, wherein the unwinding device is used for fixing and driving a carbon fiber roll to rotate; the position adjusting device is connected with the unwinding device and used for adjusting the position of the carbon fiber roll in the axial direction; the tow positioning device is used for positioning an unwinding path of the carbon fiber yarns; the control unit is in communication connection with the position adjusting device and the tow positioning device, the tow positioning device obtains the relative position between the carbon fiber yarn and the carbon fiber roll in the unwinding process while positioning the unwinding path, and the control unit controls the position adjusting device to operate according to the relative position between the carbon fiber yarn and the carbon fiber roll. The position adjusting device drives the unwinding device to move, so th
