Zusammenfassung:The invention discloses polymer vibration jet drawing method and equipment, and belongs to the technical field of polymer processing and forming machinery. The equipment comprises a vibration part, a machine body, a jet drawing part and a melting and plasticizing extrusion part; the melting and plasticizing extrusion part comprises a motor base, a motor, a coupler, a melting and plasticizing screw rod, a charging barrel, a mica heating coil that wraps the wall of the charging barrel, and a charging hopper mounted on the wall of the charging barrel; the vibration part comprises a vibration air cylinder, an air inlet and a one-way throttle valve; and the jet drawing part comprises a needle valve rod, a spray head, a temperature sensing wire and a mica heating coil. Materials are extruded and drawn from the spray head under the action of the vibration air cylinder and the needle valve rod and the pressure generated by the melt extrusion part, the diameter of a product is controlled by adjusting the size of the s
