Description

Technical Field

[0001] The utility model discloses a cable insulation layer extrusion device, which relates to the field of extrusion devices. Background Art

[0002] Cables usually include core material, insulation layer and outer sheath from inside to outside. Cables play an important role in many fields and appear in every corner of our lives. In order to increase the service life of the wire and prevent electric shock accidents, the wire is coated with an insulation layer. This insulation layer is a melted insulation material that is continuously extruded through an extrusion device under pressure and increased temperature.

[0003] In the Chinese patent with the announcement number CN214377816U, a wire and cable insulation layer extrusion device suitable for EMU is mentioned. After the raw materials are passed into the feed channel, the grinding disc and the stirring rod can rotate with the rotation of the coupling, so as to complete the grinding and stirring of the raw materials in sequence. After opening the electric valve, the raw materials after the grinding and stirring treatment fall into the feed channel, and then the raw materials can move to the left under the rotation of the screw rod to complete the subsequent operations; however, in the prior art, the heat dissipation effect of the feed channel is not good. When the heat generated and accumulated in the feed channel exceeds the heat required by the raw materials, it will affect the processing effect of the feed channel on the raw materials, reducing the practicality of the insulation layer extruder. Therefore, we introduce a cable insulation layer extrusion device. Utility Model Content

[0024] Specific implementation method: the raw materials for producing the cable insulation layer are poured into the feed mixing tank 4 for thorough mixing and stirring, and the uniformly stirred cable insulation layer raw materials are then fed into the insulation layer extruder 3 for extrusion molding.

[0026] Specific implementation method: The smoke extraction pipe 62 is started to generate suction force in the smoke inlet pipe 65, so that the smoke generated by the insulating layer extruder 3 can be sucked into the smoke removal box 61.
