The invention provides an indoor skid-mounted type
polyurethane spraying
polyethylene winding thermal-insulation tube
production line. The indoor skid-mounted type
polyurethane spraying
polyethylene winding thermal-insulation tube
production line comprises a tube loading platform I, a
steel tube rust-removal part, a tube loading platform II, a
polyurethane spraying part, a tube loading platform III, a polyurethane winding part, a
cutting part and a finished product storage part, wherein the output end of the tube loading platform I is connected with the input end of the
steel tube rust-removalpart; the output end of the
steel tube rust-removal part is connected with the input end of the polyurethane spraying part through the tube loading platform II; the output end of the polyurethane spraying part is connected with the input end of the polyurethane winding part through the tube loading platform III; the
cutting part is arranged between the polyurethane winding part and the finished product storage part; and the steel tube rust-removal part, the polyurethane spraying part and the polyurethane winding part are arranged in the form of an
inverted U. The
production line adopted by the invention is compact in structure, is relatively small in space usage, can meet good
cutting treatment of thermal-insulation tubes of different specifications, and is relatively high in applicability.
