The invention discloses one-step method high-temperature and high-pressure melt spinning equipment and a production method of a polymer fiber and relates to the one-step method high-temperature and high-pressure melt spinning equipment. The spinning equipment is characterized by comprising a driving device, an extruder system and a spinning device, wherein the driving device comprises a driving motor and a speed reducing device; the extruder system comprises an extruder screw, a charging barrel, a loading hopper, an electric heater and an extruder head; the loading hopper and the electric heater are arranged on the charging barrel of an extruder; one end of the extruder screw is connected with the driving motor through the speed reducing device; the other end of the extruder screw is matched with the extruder head. The spinning equipment also comprises a melt filtering device, a metering pump, a spinning box body and a spinning component. The spinning device sequentially comprises the metering pump, the spinning box body, the spinning component, a spinneret plate, a coldness alleviating deice, a multifilament bundling device, an oiling device, a guide device, a hot roller drafting sizing device and a winding device. The high-temperature and high-pressure melt spinning equipment is special for melt spinning of polymers with high melting point, high melt viscosity and high performance, such as polyether-ether-ketone, polyaryletherketone and polyetherimide.
