Description

Technical Field

[0001] The present invention relates to the technical field of cable production, and in particular to production equipment and a production process for high temperature resistant cables. Background Art

[0002] High temperature resistant cables are wires and cables that can work stably for a long time in a high temperature environment. They use high temperature resistant materials as conductor insulation and sheath layers, and can withstand a higher temperature range than ordinary cables. Existing high temperature resistant cables usually use polyimide, polytetrafluoroethylene and silicone rubber as insulation materials in high temperature environments. However, during the extrusion process, due to the different melting temperatures and processing characteristics of polyimide, polytetrafluoroethylene and silicone rubber (the extrusion temperature of polyimide is about 300℃-350℃; the extrusion temperature of polytetrafluoroethylene is about 340℃-370℃; and the extrusion temperature of silicone rubber is about 150℃-200℃), so multiple extruders are needed on a single high temperature resistant cable production line to complete the extrusion of different materials, or adjust the internal temperature of the extruder after each extrusion to adapt to the needs of the next layer of material. In actual operation, the following problems may occur:

[0003] 1. Using multiple extruders means more equipment and operating space is needed, which increases the complexity and management difficulty of the production line. Frequent equipment replacement and temperature adjustment will also increase the operation time, thus affecting production efficiency. In addition, the downtime and preheating time when switching materials will also lead to a longer production cycle.

[0004] 2. The processing temperature of each material is different. For example, the processing temperature of polyimide is relatively high, while that of polytetrafluoroethylene and silicone rubber is relatively low. Frequent temperature adjustment may lead to unstable temperature fluctuations, which in turn affects the processing quality of the material. If the temperature control is inaccurate, it may cause the material to overheat or underheat, affecting the insulation performance and mechanical strength of the cable;

[0005] 3. The use of multiple extruders will increase the wear of the equipment, especially in high temperature environments. The thermal expansion and alternating hot and cold conditions of the equipment may aggravate the fatigue of mechanical parts, and the maintenance and replacement costs of the equipment will also increase;

[0006] 4. When switching between different extruders, there may be consistency issues such as material thickness and surface smoothness, especially when temperature control, speed adjustment and pressure settings are different, which may affect the quality standards of the final cable and lead to the appearance of unqualified products;

[0007] 5. Due to the frequent temperature adjustment and switching of different materials, a certain amount of raw material waste and additional energy consumption may occur; for example, each time the temperature of the extruder is adjusted, it may be necessary to preheat or clean the equipment, thereby increasing material loss and electricity consumption;

[0008] Therefore, it is necessary to invent a production equipment for high temperature resistant cables. Summary of the invention

DETAILED DESCRIPTION

[0044] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0045] Embodiment 1, as Figure 1 - Fig.10 As shown, a production equipment for high temperature resistant cables in an embodiment of the first aspect of the present invention comprises a heating shell 31, a wire pay-off turret 11 is arranged on one side of the heating shell 31, a wire core winding roller 12 is rotatably mounted on the wire pay-off turret 11, a wire core is wound on the surface of the wire core winding roller 12, a wire take-up turret 18 is arranged on the other side of the heating shell 31, a wire take-up roller 19 is rotatably mounted on the wire take-up turret 18, a heat preservation liner 32 is fixedly mounted on the inner wall of the heating shell 31, a hollow structure is arranged inside the heat preservation liner 32, and an electric heating tube is fixedly mounted on the inner wall of the heat preservation liner 32 The heating pipe 35 is spirally arranged in multiple layers on the inner wall of the heat-insulating liner 32. The spacing between each layer of the heating pipe 35 increases from top to bottom. A primary heating extruder, a secondary heating extruder and a tertiary heating extruder are vertically slidably installed inside the heating shell 31. The primary heating extruder, the secondary heating extruder and the tertiary heating extruder are used to absorb the heat at different heights inside the heating shell 31 and melt the insulating material and extrude it on the surface of the wire core in sequence. Cooling equipment is arranged on both sides of the heating shell 31, and the cooling equipment is used to cool the surface of the cable that has just been extruded.

[0046] In the above embodiment, it should be noted that the heat-insulating liner 32 is made of heat-resistant ceramic material, the heating shell 31 is made of stainless steel material, and the temperature range of the heat-insulating liner 32 from bottom to top is 150°C-400°C after the electric heating pipe 35 is started for a period of time. The first-level heating extruder is responsible for extruding polytetrafluoroethylene material, the second-level heating extruder is responsible for extruding polyimide material, and the third-level heating extruder is responsible for extruding silicone rubber material.
