Description

Technical Field

[0001] The present invention relates to the technical field of cable manufacturing, and in particular to a method for manufacturing a high-voltage cable in a new energy vehicle. Background Art

[0002] In the cable production process, cable outer sheath extrusion is usually the last process of cable production. The cable outer sheath extrusion process is carried out under high temperature conditions, and then needs to be cooled with cooling water. Before the cable is loaded on the reel, the water on the cable surface must be blown dry to remove the residual water on the outer sheath surface.

[0003] In the cable processing process, in order to cool the cable after the sheath is extruded, the extrusion process uses the method of intruding into the cooling water tank behind the extruder head to reduce the cable temperature and solidify the sheath. Therefore, the cable will have water on the surface after leaving the cooling water tank. In the prior art, water removal is often carried out by wind blowing or natural drying. Natural air drying takes a long time and is easily restricted by weather. Secondly, when the air outlet is vertical to the cable, the wind blows towards the windward side of the cable, and the water will slide along the cable surface to the leeward side under the action of gravity, that is, water droplets will gather on the leeward side of the cable, which will cause incomplete water removal, thereby affecting the printing quality of the printing equipment.

[0041] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0042] like Figure 1 , Figure 2 and Figure 6 As shown, a method for manufacturing a high-voltage cable in a new energy vehicle is provided, including a table 100, a conveying wheel 101, a shower 102, an air cooling device 130, a water removal part 200 and an ejection part 300. The specific method of using the cable manufacturing device for operation is as follows:

[0043] S1, conveying the sheathed cable through the conveying wheel 101;

[0044] S2, the cable is water-cooled by the shower 102, and then cooled by the air-cooling device 130;

[0045] S3, using the airflow generated by the air cooling device 130 to push the dewatering part 200 to move, the dewatering part 200 performs dewatering work, and the dewatering part 200 impacts the ejection part 300 to make the cable separate from the dewatering part 200;

[0046] The table 100 and the upper surface of the table 100 are provided with a conveying wheel 101, a drainage groove is opened on the table 100, a shower 102 is provided above the drainage groove, and the shower 102 is connected to the liquid storage box 140 provided below the drainage groove, wherein the water in the liquid storage box 140 is extracted by the shower 102 to cool the cable, and the cooled water is recycled into the liquid storage box 140 again through the drainage groove (this process belongs to the prior art and is not described in detail here), and a drain cylinder 120 is also provided on the table 100 between the conveying wheels 101 on both sides, and air rings 110 are provided on both sides of the drain cylinder 120, and the air ring 110 is connected to The air cooling device 130 is used to cool the cable. A dewatering portion 200 and an ejection portion 300 are arranged inside the drain cylinder 120. The gas blown out by the air cooling device 130 pushes the dewatering portion 200 to move. The dewatering portion 200 moves toward the opposite side of the air ring 110 and squeezes the ejection portion 300. The ejection portion 300 lifts the cable upward to separate the cable from the dewatering portion 200, and the dewatering portion 200 squeezes out the water inside it to achieve dewatering of the cable, thereby preventing the squeezed water in the dewatering portion 200 from contacting the cable again, resulting in residual water droplets on the cable, which affects the quality of printing.

[0047] It can be seen that when the cable is dewatered under normal conditions, as the cable is transmitted, the dewatering part 200 absorbs the water droplets on the cable. During this process, the water absorbed by the dewatering part 200 will be in a saturated state. Therefore, the water inside the dewatering part 200 is squeezed out by moving the dewatering part 200 toward the ejection part 300 so as to absorb the water droplets on the cable again.

[0048] The cooling process of the cable is as follows: the cable first passes through the shower head 102 for water cooling, and water droplets are attached to the cable passing through the shower head 102. Then, the cable passes through the air ring 110, the drain cylinder 120 and the air ring 110 away from the shower head 102 in sequence, and then the air is transported into the air ring 110 through the air cooling device 130 to cool the cable again. In this process, part of the water droplets on the cable will also evaporate under the action of the air flow.

[0049] Therefore, combined with Figure 3 , Figure 4 and Figure 5As shown, the liquid storage box 140 is connected to the auxiliary box 150, and the liquid storage box 140 and the auxiliary box 150 are both provided with temperature control components, which include a memory spring 160, and the end of the memory spring 160 is fixedly connected to a support 170, and the support 170 located in the liquid storage box 140 is fixedly connected to the liquid storage box 140, and the end of the memory spring 160 away from the support 170 is fixedly connected to a movable block 171, and the movable block 171 is slidably connected to the liquid storage box 140. On the other hand, the movable block 171 is fixedly connected to one end of the traction rope 161, and the other end of the traction rope 161 is fixedly connected to a baffle 162, and a return spring 164 is sleeved on the traction rope 161, and the bottom of the return spring 164 is against the shell 163, and the top is against the baffle 162, and the shell 163 is fixedly connected to the air pipe, and the air pipe is connected to the air ring 110 near the liquid storage box 140.

[0050] In this way, when the water flow inside the liquid storage box 140 is circulated and cooled under the action of the shower head 102, the water temperature in the liquid storage box 140 increases due to heat conduction. Because the memory spring 160 has a two-way memory function, the martensite phase (phase structure at low temperature) of the memory spring 160 is a hard phase, that is, a compressed state, and the parent phase (phase structure at high temperature) is a soft phase, that is, an extended state. Low temperature refers to room temperature under normal conditions, and high temperature refers to a temperature higher than room temperature.

[0051] Next, the air ring 110 near the liquid storage box 140 is in an open state under normal conditions, that is, the traction rope 161 in this state overcomes the elastic potential energy of the return spring 164 to separate the baffle 162 from the air pipe. When the temperature inside the water storage box 140 rises, the memory spring 160 releases the traction rope 161 with the assistance of the return spring 164. The released memory spring 160 gradually blocks the air pipe, so that the gas inside the air pipe no longer flows into the air ring 110 near the liquid storage box 140. Then, the gas in the air pipe flows to the air ring 110 on the opposite side, so as to provide power for the gas to push the water removal part 200 in the later stage.

[0052] Then, based on the above structure, Figure 6 The structure of the water removal part 200 is further disclosed. The water removal part 200 includes a first sponge 210 and a movable plate 220. The first sponge 210 is bonded to the movable plate 220. Under normal conditions, the first sponge 210 fits the cable. The movable plate 220 is provided with protrusions at both ends. The inner wall of the hydrophobic cylinder 120 is provided with a slide groove. The protrusion slides in the slide groove. The movable plate 220 is coaxially connected with a retaining ring 221. During the transmission of the cable, water droplets gather at the bottom of the cable under the action of gravity. The water droplets are absorbed after passing through the first sponge 210, thereby preventing moisture from remaining on the cable and affecting the printing quality of the printing device.

[0053] In addition, the inner walls of the air rings 110 on both sides are connected with exhaust pipes 111. The ends of the exhaust pipes 111 near the cables are provided with air holes perpendicular to the cables. The air holes are connected with side air holes, which point to the movable plate 220. The inner walls of the air rings 110 near the movable plate 220 are provided with conical buckets 112, which are located outside the exhaust pipes 111. In this way, when the air pipes are blocked, the air holes at the ends of the exhaust pipes 111 are blocked by the baffle rings 221, so the air flow is discharged from the side air holes to the movable plate 220. In order to increase the flow rate of the air flow ejected from the side air holes, pressure relief valves are provided in the side air holes. Therefore, the air pipes at both ends are in a blocked state at this time, and the pressure in the air pipes increases. When the air pressure breaks through the pressure relief valve, the ejected air flow is used to push the movable plate 220 to move toward the ejection part 300. During this process, the movable plate 220 moves like a piston. When the first sponge 210 is pressed against the ejection portion 300, the first sponge 210 squeezes out the moisture inside, thereby keeping the first sponge 210 dry so as to absorb the moisture on the cable again.

[0054] It should be noted that after the airflow instantly breaks through the pressure relief valve, the airflow is divided into two streams, one stream pushes the movable plate 220 to move, and the other stream flows out from the gap between the cable and the conical bucket 112 .

[0055] In order to return the movable plate 220 to its original position after the water in the first sponge 210 is squeezed out, a tension spring 222 is provided on the opposite side of the movable plate 220 and the first sponge 210. The tension spring 222 is symmetrically arranged, and the end of the tension spring 222 is fixedly connected to the movable plate 220, and the other end of the movable plate 220 is fixedly connected to the air ring 110. In the process of the movable plate 220 moving toward the ejection portion 300, the airflow pushes the movable plate 220 to overcome the elastic potential energy of the tension spring 222. When the movable plate 220 moves to the maximum displacement (i.e., the water in the first sponge 210 is squeezed out), the thrust of the airflow on the movable plate 220 disappears, and the elastic action of the tension spring 222 pulls the movable plate 220 in the opposite direction to make the movable plate 220 return to its original position, and the retaining ring 221 blocks the air hole again.

[0056] Below Figure 6 Based on and combined with Figure 7As shown, the structure of the ejection part 300 is disclosed. The ejection part 300 includes an airbag 310 and a second sponge 320. The airbag 310 is bonded to the bottom of the second sponge 320. An arc plate 330 is bonded to one side of the second sponge 320, and the other side is against the wind ring 110 close to the arc plate 330. Auxiliary rods 331 are fixedly connected at both ends of the arc plate 330. A tripod 332 is slidably connected above the auxiliary rod 331. The tripod 332 is slidably connected to a sliding rod 333. The sliding rod 333 is fixedly connected to the wind ring 110 close to the arc plate 330. In this way, when the curved plate 330 is hit, the second sponge 320 is squeezed under the action of the curved plate 330 and the air ring 110, and the tripod 332 slides on the slide rod 333. During this process, as the movable plate 220 moves, on the one hand, the moisture inside the second sponge 320 is squeezed out, and on the other hand, the squeezed airbag 310 expands, causing the second sponge 320 to push upward. The second sponge 320 and the curved plate 330 move upward to lift the cable, thereby preventing the first sponge 210 from expanding outward when being squeezed, causing the squeezed moisture to contact the surface of the cable again, and the moisture remains on the surface of the cable, affecting the quality and effect of printing.

[0057] After the squeezing of the arc plate 330 by the first sponge 210 disappears, the arc plate 330 moves downward under the action of gravity and returns to the initial state. While the cable is detaching from the first sponge 210, the second sponge 320 absorbs the moisture on the cable. As the first sponge 210 returns to its original position, the first sponge 210 contacts the cable again. In this way, the first sponge 210 and the second sponge 320 alternately remove moisture from the cable, thus avoiding the phenomenon of missing moisture after the cable is detached from the first sponge 210.

[0058] Further, in Figure 6 Based on and combined with Figure 2 As shown, a drain pipe 121 is provided at the bottom of the drain cylinder 120 , and the drain pipe 121 connects the drain cylinder 120 and the auxiliary box 150 , so that the squeezed water flows back to the inside of the auxiliary box 150 through the drain pipe 121 .

[0059] Return to Figure 3 and Figure 5As shown, a water supply pipe 141 and a return pipe 142 are connected between the liquid storage box 140 and the auxiliary box 150, a pump body 143 is arranged inside the water supply pipe 141, and a movable block 171 inside the auxiliary box 150 is fixedly connected with a blocking rod 180, and the blocking rod 180 is used to block the water supply pipe 141. Because the water droplets on the cable flow back into the auxiliary box 150 after being cooled by air cooling, the water temperature in the auxiliary box 150 is reduced. Under the action of the memory spring 160, the memory spring 160 pulls the blocking rod 180 to move toward the support 170, and the blocking rod 180 is separated from the blocking of the water supply pipe 141. Under the action of the pump body 143, the cold water in the auxiliary box 150 is transported to the liquid storage box 140, and the water temperature in the liquid storage box 140 is reduced, thereby improving the cooling effect on the cable.

[0060] At the same time, the water in the liquid storage box 140 flows back to the auxiliary box 150 through the return pipe 142. After the hot water is mixed with the cold water in the auxiliary box 150, the water temperature in the auxiliary box 150 increases, causing the blocking rod 180 to block the water supply pipe 141 again. Figure 4 and Figure 5 As shown, after the water temperature in the liquid storage box 140 drops, the traction rope 161 pulls the baffle 162 to open the air pipe again, while the air pipe on the other side is in a closed state. This cycle not only removes water from the cable, but also cools the cable to reduce the number of times the water in the liquid storage box 140 is replaced and improve the cooling effect.

[0061] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
