Fiber fuzzing amount testing device

The utility model discloses a fiber fuzzing amount testing device, which particularly relates to the technical field of composite material carbon fiber tow process testing, and comprises a frame body, and a fiber unwinding mechanism, a fiber guide mechanism, a broken filament amount collecting mechanism and a fiber winding mechanism which are sequentially arranged on the frame body, a fiber tow released by the fiber unwinding mechanism is unfolded through the fiber guiding mechanism, then broken filaments generated by the fiber tow are collected by the broken filament collecting mechanism, and finally the fiber tow is wound into a finished product through the fiber winding mechanism, and the fiber guiding mechanism comprises at least two guiding devices. The guide device comprises a wire guide round rod, a base, a base fixing part and a wire guide round rod fixing part, the base can be fixed or move on the frame body by adjusting the base fixing part, and the wire guide round rod can rotate or be fixed in the
