This invention relates to a rotary station extrusion blow molding equipment. To address the water and air supply structure issues in hollow plastic bottle extrusion blow molding machines, this invention discloses a water and air supply device for a rotary station extrusion blow molding machine. It includes a water connector, an air connector, a water pipe, and an air pipe. Its key feature is the inclusion of a rotary joint, a rotary shaft, a fixed sleeve assembly, and an air distribution manifold. The water pipe and air pipe are externally connected to the rotary shaft. The upper part of the rotary shaft is connected to the air distribution manifold via screws, and the lower part of the rotary shaft is connected to the fixed sleeve assembly via screws. The shaft head inside the fixed sleeve assembly is connected to the rotary joint below. This invention designs a water and air supply device where the rotary shaft and fixed sleeve assembly are coaxial and water-air shielded. All flow channels can be disassembled in sections, offering advantages such as compact structure and sufficient flow.
