[0001] This invention relates to the field of cables, and in particular to a cable and its processing method. Background Technology

[0002] Cables and wires, as carriers of electrical energy and information, are widely used in various fields. Moreover, most cables and wires are used outdoors, and therefore, they are exposed to various climatic conditions, especially exposure to sunlight and large temperature changes, which accelerate the aging of the cables. Therefore, it is necessary to add an anti-aging protective layer to the outside of the cable. Summary of the Invention

[0003] The purpose of this invention is to provide a cable and its processing method, which increases the anti-aging performance of the cable by adding an anti-aging layer to the outside of the cable.

[0037] like Figure 1-12 The cable processing method is described in detail below:

[0038] A cable processing method includes the following steps:

[0039] S1. Wrap an insulating layer around the copper conductor and set aside.

[0040] S2. Heat the anti-aging rubber to a molten state;

[0041] S3. The molten anti-aging rubber is wrapped around the copper conductor with an insulating layer using a processing device;

[0042] S4, and through the processing device, the molten anti-aging rubber is rapidly cooled and wrapped around the outside of the insulation layer to form an anti-aging layer.

[0043] like Figure 1-12 The processing apparatus is described in detail below:

[0044] The processing device includes a cavity tube 203, a tapered tube 204, a feeding tube 206, a forming head 401, a rotating seat 402, and a spiral plate I 403; the tapered tube 204 is located at one end of the cavity tube 203, the rotating seat 402 rotates at the other end of the cavity tube 203, the spiral plate I 403 is fixed on the rotating seat 402 and located inside the cavity tube 203, the forming head 401 is detachably connected to the end of the tapered tube 204 away from the cavity tube 203, and the feeding tube 206 is fixed to the side of the cavity tube 203.

[0045] In use, molten anti-aging rubber is introduced into cavity tube 203 through feeding tube 206; at the same time, copper conductor with insulation layer is inserted through the feed hole in the center of rotating seat 402, so that copper conductor with insulation layer passes through the center of spiral plate I 403 and enters tapered tube 204, and then moves out through the forming hole of forming head 401. During this process, rotating seat 402 rotates, which in turn drives spiral plate I 403 to rotate, thereby pushing the molten anti-aging rubber in cavity tube 203 into tapered tube 204. During the process of pushing from tapered tube 204 to forming head 401, the space becomes smaller, thereby compressing the molten anti-aging rubber, so that the molten anti-aging rubber can tightly wrap around the outside of copper conductor insulation layer, and slide out through the forming hole of forming head 401 as copper conductor moves, forming a shaping and wrapping of molten anti-aging rubber wrapped around the outside of copper conductor insulation layer;

[0046] The forming head 401, rotating seat 402, and spiral plate I 403 are all detachable and replaceable components. These components can be replaced according to the diameter of the copper conductor insulation layer, ensuring that the forming hole of the forming head 401 corresponds to the diameter of the copper conductor insulation layer. Furthermore, the thickness of the molten anti-aging rubber can be controlled through the forming hole of the forming head 401. Simultaneously, by replacing the spiral plate I 403, the internal core diameter of the spiral plate I 403 corresponds to the diameter of the copper conductor insulation layer. Thus, while the spiral plate I 403 rotates to push the molten anti-aging rubber, the core spirally pushes the copper conductor wrapped with the insulation layer, improving the movement efficiency of the copper conductor wrapped with the insulation layer.

[0047] Further:

[0048] The processing device also includes a cooling box 101, side circular plates 102, a central shaft 103, guide wheels I 104 and II 105, and an arc baffle 201. The two side circular plates 102 are respectively fixed on both sides of one end of the cooling box 101. The central shaft 103 rotates at the center of the two side circular plates 102. The guide wheels I 104 are fixed on the central shaft 103. The guide wheels II 105 rotate above the end of the cooling box 101 away from the side circular plates 102. The arc baffle 201 is connected to the outer edge of the two side circular plates 102. The cavity tube 203 is fixed through the arc baffle 201.

[0049] The cooling box 101 is used to hold cooling water, and the arc baffle 201 and the two side circular plates 102 form a seal on one end of the cooling box 101. The copper conductor wrapped with molten anti-aging rubber extruded from the forming hole of the forming head 401 can directly enter the cooling water for cooling and molding, so that the molten anti-aging rubber can be cooled and shaped quickly. Then, the copper conductor wrapped with molten anti-aging rubber can enter the cooling water through the guide wheel I 104, and the copper conductor with the anti-aging layer formed can be guided out of the cooling water through the guide wheel II 105. Finally, it is wound up and stored.

[0050] Further:

[0051] The centerline of the cavity tube 203 is tangent to the outer edge of the guide wheel I 104.

[0052] By setting the tangentially, the copper conductor wrapped with molten anti-aging rubber extruded from the forming hole of the forming head 401 can avoid bending when it moves toward the guide wheel I 104, thus ensuring the shape of the molten anti-aging rubber and the quality of the anti-aging layer.

[0053] Further:

[0054] Two support plates 202 are fixed at both ends of the arc baffle 201, and the two support plates 202 rotate at both ends of the central shaft 103.

[0055] By setting up two support plates 202, the arc baffle 201 can drive the cavity tube 203 to rotate on the two side circular plates 102 with the central axis 103 as the axis. During the rotation, the center line of the cavity tube 203 is always tangent to the outer edge of the guide wheel I 104. Thus, while ensuring that the copper conductor wrapped with molten anti-aging rubber between the forming head 401 and the guide wheel I 104 is not bent, the water immersion length of this section of copper conductor can be controlled. The water immersion length of this section of copper conductor can be controlled according to the thickness of the anti-aging rubber layer. The thicker the layer, the longer the water immersion length, the better the cooling effect, and the faster the forming. Conversely, the thinner the layer, the shorter the water immersion length, the worse the cooling effect, and the slower the forming. This ensures that the anti-aging rubber can be cooled and formed when this section of copper conductor moves to the guide wheel I 104, avoiding deformation when guided by the guide wheel I 104.

[0056] Moreover, by rotating the arc baffle 201, the center line of the cavity tube 203 can be kept vertical at the beginning of processing. This state facilitates the initial introduction of the molten anti-aging rubber and copper conductor into the cavity tube 203. As processing progresses, the arc baffle 201 is rotated until the forming head 401 is immersed in the cooling water. This effectively prevents the cooling water from entering the cavity tube 203 first and affecting the processing.

[0057] like Figure 1-12 As shown:

[0058] The cross frame 106 is fixed on the two side circular plates 102. The drive shaft 301 rotates on the cross frame 106 and is meshed with the arc baffle 201 for transmission. The worm gear 302 rotates on the cross frame 106 and is connected to the worm wheel on the drive shaft 301 for transmission.

[0059] By rotating the worm gear 302, the transmission worm wheel can be engaged to drive the transmission shaft 301 to rotate, and then the transmission arc baffle 201 drives the cavity tube 203 to rotate, thereby adjusting the length of the copper conductor wrapped with molten anti-aging rubber between the molding head 401 and the guide wheel I104, so that the cooling degree is adapted to the thickness of the anti-aging rubber layer, ensuring the continuous cooling effect of the cooling water.

[0060] like Figure 1-12 As shown:

[0061] The tensioning frame 601 rotates on the central shaft 103 and is located inside the cooling box 101. The guide wheel Ⅲ 602 rotates at the end of the tensioning frame 601 away from the central shaft 103. A tension spring 603 is provided between the tensioning frame 601 and the end of the cooling box 101 away from the central shaft 103.

[0062] Throughout the entire processing, the equipment at the rear end that winds the cable simultaneously exerts a pulling force on the copper conductor wrapped with the insulation layer, ensuring that the copper conductor wrapped with the insulation layer can continuously move within the cavity tube 203. However, when the position of the cavity tube 203 is adjusted by the worm gear 302 during processing, although the copper conductor wrapped with molten anti-aging rubber between the forming head 401 and the guide wheel I 104 is kept unbent, the length of the copper conductor from the forming head 401 to the guide wheel II 105 remains unchanged, but the wrap angle with the guide wheel I 104 changes, thus requiring... While maintaining the tension of the copper conductor between the forming head 401 and the guide wheel I 104, the path is adjusted. This is achieved by setting up a tensioning frame 601. Through the elastic force of the tension spring 603, the guide wheel III 602 tensions the copper conductor between the forming head 401 and the guide wheel II 105. When the arc baffle 201 rotates, the tensioning frame 601 overcomes the tension spring 603 and drives the guide wheel III 602 to rotate. This ensures that the overall length of the copper conductor between the forming head 401 and the guide wheel I 104 remains unchanged and that the path is adjusted while maintaining the tension, thus avoiding damage to the copper conductor or the anti-aging rubber layer.

[0063] like Figure 1-12 As shown:

[0064] The outer frame 205 is fixed to the end of the cavity tube 203 away from the tapered tube 204. Two support frames 501 slide on both sides of the outer frame 205 respectively. There are clamping wheels 502 rotating between the two support frames 501. Each support frame 501 and the outer frame 205 are provided with a spring 503 so that the two clamping wheels 502 press against each other.

[0065] The two clamping wheels 502 clamp each other to clamp the copper conductor entering the feed hole in the center of the rotating seat 402, thereby effectively preventing the copper conductor from bending and squeezing at the feed hole port, which would damage the copper conductor or insulation layer.

[0066] like Figure 1-12 As shown:

[0067] Both stirring shafts 701 rotate at their lower ends within the cooling box 101, and both stirring shafts 701 are fixed with spiral plates II 702.

[0068] The first motor installed at the lower end of the cooling box 101 drives the two stirring shafts 701, causing the two stirring shafts 701 to drive the two spiral plates II 702 to rotate at the lower end inside the cooling box 101, forming a spiral push and stirring of the cooling water. This causes the cooling water in the cooling box 101 to flow between the two side circular plates 102, thereby making the overall temperature of the cooling water uniform and better cooling the anti-aging rubber layer.

[0069] The cable prepared by the aforementioned cable processing method has an external anti-aging layer wrapped around its exterior.

[0070] By adding an anti-aging layer, the cable's anti-aging performance can be enhanced when used outdoors, as it is affected by climate.
