Abstract

An electrospinning nanofiber membrane preparing device with a heating function relates to electrospinning nanofiber preparing devices. A spray head is fixed on a liquid supply device, and a rotary drum is internally provided with an electric heating element; one end of a rotary drum shaft is a metal electrode which is connected with the negative pole of a high-voltage power supply and is grounded; one end of an insulating rod is connected with an output shaft of a rotating motor, and the other end of the insulating rod is fixedly connected with the metal end of a rolling shaft; the other end of the rolling shaft is insulated, and a hollow wire connecting hole is formed in the end of the rotary drum shaft; a temperature measuring element is arranged on the surface of the rotary drum; the temperature measuring element is connected with a numerical-control temperature unit which is connected with a relay, and the relay is connected with the electric heating element so as to form a temperature control part; an arc-shaped heat-insulating cover is coaxial with the rotary drum and is fixed on a heat-insulating cover support frame; a rotary drum support frame and a motor support frame are installed on a horizontal moving device; and the horizontal moving device is connected with a translation motor. According to the invention, ordered deposition of the nanofiber, control on uniformity of the nanofiber membrane and heating of the nanofiber in the electrospinning process can be completed synchronously.

Description

technical field [0001] The invention relates to an electrospinning nanofiber preparation device, in particular to an electrospinning nanofiber film preparation device with heating function. Background technique [0002] Nanofibers have attracted extensive attention from academia and industry due to their unique advantages. In recent years, research on the manufacture and application of nanofibers has become one of the hotspots in the fields of micro-nanotechnology, advanced manufacturing, textiles, and biomedicine. Various nanofiber preparation techniques have been developed. [0003] Electrospinning technology based on electrospinning coupled with jet printing is one of the common methods for preparing nanofibers. Compared with other preparation technologies, electrospinning has the advantages of simple equipment, convenient operation, strong material applicability, and high viscosity of spray-printable solutions, so it has developed rapidly in recent years. Electrospinni...
