A group of limit guide rods 13 limit and guide the unwound round steel wire rod during the conveying process, ensuring that the single round steel is continuously conveyed. When the round steel wire rod is less, the second hydraulic cylinder 32 drives the swing rod 34 to swing, so that the limiting frame 31 rotates, and the limiting wheel 33 gradually approaches the round steel wire rod and extrudes the round steel wire rod to limit and block the round steel wire rod, reducing the swing amplitude of the round steel wire rod during the conveying process and improving the conveying stability of the round steel wire rod. When the round steel wire rod is conveyed through the second channel, the round steel is limited and rectified through the cooperation of the down pressure wheel 42 and the bracket 4, so that the round steel is conveyed horizontally.
