Conventional melt spinning uses a heating rod to heat the polymer melt, and the heating rod heats the local temperature high and is not easy to control. At the same time, the heating rod is easily damaged relative to electromagnetic heating.

[0004] To this end, we propose an electromagnetic heating device for spinning melt processing. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: when the electromagnetic heating device for spinning melt processing is used, the electromagnetic coil connected to the outer wall of the melting pipe is energized to generate a high-frequency magnetic field, which heats the melting pipe, so that the polymer melt passing through the melting pipe is melted to meet the polymer melt processing requirements. The device adopts electromagnetic heating, which has fast heating, precise temperature control, and is not easy to break. Compared with conventional heating rod heating, the local temperature of the heating rod is high and difficult to control. At the same time, the heating rod is easily damaged compared with electromagnetic heating.

[0013] The feed barrel serves as the access pipe of the melt pipeline. The polymer melt flows into the feed barrel in the form of fluid, and is ejected from the spinneret through the spinneret under pressure to meet the processing requirements of melt spinning. The spinneret is connected to the feed barrel by bolt-tightening, which is convenient for users to replace and clean the spinneret in time.
