Today, a patent of the company was authorized by the China National Intellectual Property Administration. The name of this patent is "a polyurethane sandwich panel casting sprinkling rod", patent number: CN201821171169.3 。
The utility model discloses a casting sprinkler rod for the production of polyurethane sandwich panels, comprising a polyurethane sandwich panel surface material. The upper end of the polyurethane sandwich panel surface material is provided with a sprinkler pipe, and two sets of first connecting elbows are symmetrically arranged on both sides of the surface of the sprinkler pipe. The first connecting elbows are fixedly connected to an adapter tee pipe through a guide steel pipe, and the other end opening of the adapter tee pipe is fixedly connected to a second connecting elbow.
The polyurethane sandwich panel is used to produce a pouring rod, which changes the direction of the material through a second connecting elbow connected to the mixing head of the foaming machine to achieve collision and mixing again, improving and compensating for the mixing effect of the mixing head of the foaming machine. The spraying tube is processed by injection molding, and the inner wall and spraying hole are smooth, regular, and high-precision, making the pouring and spraying uniform.
