[0002] PVC, primarily composed of polyvinyl chloride, is a material with added components to enhance its heat resistance, toughness, and ductility. During the production of PVC pipes, high-temperature extrusion molding necessitates cooling after molding, requiring cooling equipment. Existing technology publication CN221067145U discloses a cooling device for PVC pipe production, comprising a base plate, a water-cooling box above the base plate, a return water pipe below the water-cooling box, a limit block above the base plate, a water pump below the water-cooling box, a pump base below the water pump, a water storage tank on the side of the water pump, a connecting flange between the water storage tank and the water pump, a discharge port on the side of the water-cooling box, and a cooling pipe inside the upper part of the water-cooling box. However, during use, the cooling water cannot be evenly sprayed onto the PVC pipe, resulting in uneven cooling. After cooling, water adheres to the outer wall of the hose, affecting subsequent winding and collection. Utility Model Content
