Slurry-free fiber yarn releasing device

The invention discloses a sizing-free fiber yarn releasing device which comprises a machine frame, a yarn releasing barrel set, a guide wheel set, a yarn dividing groove roller and a traction roller set, the machine frame is provided with a yarn inlet end and a yarn outlet end, and the yarn releasing barrel set, the guide wheel set, the yarn dividing groove roller and the traction roller set are all installed on the machine frame. The guide wheel sets are arranged in sequence in the direction from the yarn inlet end to the yarn outlet end, each guide wheel set comprises a plurality of rotatable guide wheels, and guide grooves with smooth surfaces are formed in the guide wheels. According to the sizing-free fiber yarn releasing device, the guide wheel set and the yarn separating grooved roller are arranged to separate sizing-free fibers, and due to the fact that the surfaces of guide grooves in the guide wheels are smooth, the problems of yarn breaking and fuzzing in the yarn separating process can be effectiv
