The invention discloses a continuous steel bar winding and coiling processing apparatus. A left-right reciprocating type sliding wire inlet rack is arranged on a body, and an inlet hole allowing a steel bar to be processed to pass through is arranged on the wire inlet rack. A reel is arranged behind the wire inlet rack and connected with the rotating shaft of a power apparatus. The reel when driven by the power apparatus rotates to coil the steel bar to be processed onto the reel. A motor is arranged on the body, the output shaft of the motor is connected with a screw, and the lower end of the wire inlet rack is provided with a nut cooperating with the screw. When the output shaft of the motor drives the screw to rotate, the wire inlet rack is driven to move left and right under the nut. The continuous steel bar winding and coiling processing apparatus carries out continuous and orderly coils steel bars, and prevents being nonuniform and offsetting during winding of the steel bars. In subsequent use, the continuous steel bar winding and coiling processing apparatus can be used with corresponding apparatuses to effectively prevent disorder of the steel bars and fast knot due to twisting of the steel bars. The continuous steel bar winding and coiling processing apparatus improves the winding and processing efficiency, and accelerates a construction progress.
