The automatic steel bar tying machine is an intelligent device that can quickly complete steel bar tying through motor drive or semi-automatic operation. Its core principle is to use a mechanical arm or rotating claw to accurately grab the binding wire and complete the knot around the intersection of the steel bars, replacing the traditional manual operation. This type of tool is suitable for tying steel bars with a diameter of 8-34mm and can be widely used in residential buildings, bridges, tunnels and other scenes.
