[0031] Please refer to Figures 1 to 3 The utility model provides a spinneret insulation structure, comprising an insulation seat 1, wherein the insulation seat 1 comprises an insulation outer layer 12 and a heating inner layer 11;

[0032] The heat-insulating outer layer 12 is a toroidal structure and is made of heat-insulating material;

[0033] The heating inner layer 11 is arranged in the heat-insulating outer layer 12 and is made of a heat-conducting metal material. The heating inner layer 11 is provided with a connecting hole 16 corresponding to the spinneret hole on the spinneret 3. The heating inner layer 11 is provided with an electric heating wire 13.

[0034] When in use, the spinneret 3 is installed on the heating inner layer 11, and the electric heating wire 13 inside the heating inner layer 11 can heat the polymer melt in the connecting hole 16. After the heating inner layer 11 is preheated before use, the viscous polymer melt flows from the spinneret hole of the spinneret 3 into the connecting hole 16 of the heating inner layer 11, which can avoid the viscous polymer melt from undergoing phase change. In the subsequent production process, the temperature inside the insulation seat 1 can be stabilized by relying on the heat of the polymer melt itself and the insulation of the insulation outer layer 12, thereby ensuring the stability of the spinning production effect.

[0035] In this embodiment, the spinneret holes on the spinneret plate 3 are arranged in a rectangular array, and the heating wire 13 passes through the aisles between adjacent rows of spinneret holes in sequence and forms a continuously bent wave shape. The arrangement of the wavy heating wire 13 can achieve uniform heating of the polymer melt in the connecting hole 16 of the heating inner layer 11.

[0036] In this embodiment, a plug-in tube corresponding to the spinneret is provided at the bottom of the spinneret 3, a plug-in groove corresponding to the plug-in tube is provided at the top opening of the connecting hole 16, and a truncated cone-shaped discharge hole is provided at one end of the bottom of the connecting hole 16. By providing the plug-in tube and the plug-in groove, the spinneret 3 can be embedded in the installation, and the installation of the spinneret 3 is more stable.

[0037] In this embodiment, a connecting seat 2 is also included, which includes an upper seat body 21 and a pressure ring 22. The connecting seat 2 is a circular ring structure, and the inner diameter of the connecting seat 2 is smaller than the diameter of the spinneret 3. The pressure ring 22 is fixed to the bottom of the connecting seat 2, and the outer diameter of the pressure ring 22 is the same as the diameter of the spinneret 3, and the inner diameter of the pressure ring 22 is the same as the inner diameter of the connecting seat 2. By setting the connecting seat 2, the spinneret 3 can be fixed between the connecting seat 2 and the insulation seat 1.

[0038] In this embodiment, a sealing groove 15 is provided on the top of the insulation outer layer 12, and a sealing ring 4 is provided in the sealing groove 15. The setting of the sealing ring 4 can prevent cold air from flowing between the connecting seat 2 and the insulation seat 1, thereby affecting the spinning effect.

[0039] In this embodiment, the sealing ring 4 is made of fluororubber. The sealing ring 4 made of fluororubber is resistant to high temperatures and can be used in a high temperature environment between the connecting seat 2 and the heat preservation seat 1 .

[0040] In this embodiment, the outside of the insulation seat 1 is provided with multiple connecting lower protrusions 14 at equal intervals along its circumference, and the outer wall of the connecting seat 2 is provided with connecting upper protrusions 23 corresponding to the connecting lower protrusions 14, and the connecting lower protrusions 14 and the corresponding connecting upper protrusions 23 are fastened together by bolts.

[0041] The working principle of this utility model is as follows:

[0042] The spinneret 3 is installed on the heating inner layer 11, and the electric heating wire 13 inside the heating inner layer 11 can heat the polymer melt in the connecting hole 16. After the heating inner layer 11 is preheated before use, the viscous polymer melt flows from the spinneret hole of the spinneret 3 into the connecting hole 16 of the heating inner layer 11, which can avoid the viscous polymer melt from undergoing phase change. In the subsequent production process, the temperature inside the insulation seat 1 can be stabilized by relying on the heat of the polymer melt itself and the insulation of the insulation outer layer 12, thereby ensuring the stability of the spinning production effect.
