Description

Technical Field

[0001] The utility model relates to the technical field of cable processing and belongs to a high-temperature extrusion device for processing fluoroplastic cables. Background Art

[0002] In the cable processing industry, fluoroplastic cables are widely used due to their excellent high temperature resistance and corrosion resistance. Due to their special material properties, fluoroplastic cables need to be extruded under high temperature conditions to ensure the quality and performance of the cables. Therefore, the design and use of this high temperature extrusion device is of great significance for the production of fluoroplastic cables.

[0003] In terms of working principle, the high temperature extrusion device for fluoroplastic cables is mainly based on the thermoplastic principle of plastics. Under the action of the heating system, the raw materials are heated to a molten state, and then pushed into the mold by the screw to form a cable of the desired shape. Subsequently, through the cooling effect of the cooling system, the cable is quickly shaped and solidified.

[0004] At present, the cable entry port diameter of many high-temperature extruder cooling mechanisms is fixed, which means that it can only adapt to the processing of cables of specific specifications. When processing cables of different specifications, it may be necessary to replace the entire entry port part or adjust the entire equipment, which not only increases the complexity of operation, but also reduces production efficiency. The existing cooling mechanism has a single cooling form and the cooling effect is not ideal, resulting in uneven cable surface temperature or thermal damage. Utility Model Content
