Description

Technical Field

[0001] The present invention relates to the technical field of charging pile cables, and in particular to a method for manufacturing a reinforced torsion-resistant charging pile cable. Background Art

[0002] With the increasing popularity of electric vehicles, the demand for charging piles is growing. As a key component connecting charging piles to electric vehicles, charging pile cables are subject to increasingly stringent performance requirements. In practice, charging pile cables need to be bent and reeled, subjecting them to frequent mechanical stresses such as bending and torsion.

[0003] During use, the charging pile cables currently on the market often suffer from problems such as damage to the internal structure of the cable, degradation of electrical performance, and sheath rupture due to torsion, which seriously affects the normal use of the charging piles and the charging safety of electric vehicles.

[0004] In order to solve these problems, reinforced torsion-resistant charging pile cables came into being; when manufacturing this type of cable, one of the key steps is to mix and extrude the raw materials of the cable.

[0005] There are many existing technologies for cable extruders, such as:

[0006] Chinese patent publication number CN108995171B discloses an extruder for processing wires and cables with a crushing function, which includes a shell, a crushing mechanism, a stirring mechanism and a cooling mechanism. An extrusion box is provided inside the shell, an extrusion head is provided below the shell, a stirring chamber is provided at the top of the shell, a melting chamber is provided above the stirring chamber, a crushing mechanism is provided above the melting chamber, stirring mechanisms are provided on both sides of the stirring chamber, and a cooling mechanism is provided on the extrusion head. The crushing mechanism is provided on the extruder for processing wires and cables, and the user can crush the raw materials put into the extruder for processing wires and cables through the crushing mechanism, so that the extruder for processing wires and cables has a better melting effect on the raw materials.

[0007] It can be seen that in the mixing process of most cable extruders, the fluidity of the raw materials is poor, which will lead to uneven mixing and affect the quality and performance consistency of the cable; at the same time, the raw materials are fused by heating during the mixing process, which not only increases the consumption of electricity and causes economic costs to rise, but also mixes in gas. If it cannot be effectively discharged, bubbles will form in the cable. These bubbles will weaken the insulation performance of the cable and increase the risk of breakdown, thereby shortening the service life of the cable.

[0008] In view of this, we propose a manufacturing method for a reinforced torsion-resistant charging pile cable. Summary of the Invention

[0009] The object of the present invention is to provide a method for manufacturing a reinforced torsion-resistant charging pile cable to solve the problems raised in the above background technology.

[0010] To achieve the above object, the present invention provides a method for manufacturing a reinforced torsion-resistant charging pile cable, comprising the following steps:

[0013] S3. Quality inspection: Conduct strict inspection on the cables to check their electrical performance, mechanical performance and appearance;

[0014] In the above process, the extrusion equipment used includes a crushing shell, a heat preservation barrel and a shell. Two support columns are provided on both sides of the lower side of the crushing shell for fixed connection with the heat preservation barrel. A crushing knife capable of crushing the raw materials is provided inside the heat preservation barrel.

[0015] A fusion component is provided inside the heat preservation barrel, flow components are provided on both sides of the upper side of the heat preservation barrel, and a feeding component capable of diverting the raw materials is provided on the inner wall below the heat preservation barrel;

[0016] The fusion component can stir the raw materials and rub the inner wall of the insulation barrel to increase the temperature inside the insulation barrel, so that the raw materials are heated and fused, and the fusion component cleans the inner wall of the insulation barrel;

[0017] The smooth flow component can change the direction of the raw material flow. At the same time, the fusion component drives the smooth flow component to move upward, so that the gas in the raw material inside the insulation barrel is discharged;

[0018] An extrusion assembly capable of extruding two insulating layers is arranged inside the shell.

[0019] As a further improvement of the present technical solution, the fusion assembly includes at least a rotating shaft, and the outer wall of the rotating shaft is provided with multiple groups of fusion rods, the multiple groups of fusion rods are arranged in a circular array, and a flow rod is provided at the end of each group of fusion rods away from the rotating shaft.

[0020] As a further improvement of the present technical solution, the flow assembly includes at least a flow plate, connecting plates are provided on both sides of the flow plate, exhaust grooves are provided on both sides above the insulation barrel, and an elastic part is provided on the upper surface of the connecting plate, and the upper end of the elastic part is fixedly connected to the inner wall of the exhaust groove.

[0022] As a further improvement of the present technical solution, the extrusion assembly includes at least two flow columns, the two openings below the heat preservation barrel are fixedly connected to the tops of the two flow columns respectively, an auger is provided inside the two flow columns, and a drainage pipe is provided below the outer wall of the two flow columns, the drainage pipe extends from one end away from the flow column to the bottom of the shell, and is fixedly connected to a double-layer extrusion head.

[0023] As a further improvement of the present technical solution, sealing strips are provided at the upper and lower ends of the two openings below the heat preservation barrel.

[0024] As a further improvement of the present technical solution, the flow-following rod is wavy in shape.

[0025] As a further improvement of the present technical solution, the heat preservation barrel is made of an alloy material with good thermal conductivity and wear resistance, and the flow-smoothing rod is made of a polymer composite material.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. In the manufacturing method of the reinforced torsion-resistant charging pile cable, the fluidity of the raw materials is effectively increased by using the combination of fusion components and free-flow components, which enables the various raw material components to be fully integrated in a short time, saving time and production costs, reducing economic consumption, and can also timely and efficiently discharge the gas in the raw materials, ensuring the density and high quality of the final product, greatly improving the torsion resistance of the charging pile cable production, thereby increasing the service life of the charging pile cable.

[0028] 2. In the manufacturing method of the reinforced torsion-resistant charging pile cable, the fusion component can stir the raw materials and rub the inner wall of the insulation barrel to increase the temperature inside the insulation barrel. While the raw materials are heated and fused, the fusion component cleans the inner wall of the insulation barrel to reduce the probability of raw material waste. This not only improves the work efficiency of the charging pile cable production, but also reduces the consumption of electricity, saves costs, and thus reduces economic losses.

[0029] 3. In the manufacturing method of the reinforced torsion-resistant charging pile cable, the raw materials are fed through the feeding assembly, which not only improves the flexibility of the extruder and controls the speed of the raw material flow, but also diverts the raw materials and assists the extrusion assembly to extrude two layers of insulation, thereby increasing the strength and protective performance of the charging pile cable, and also increasing the torsion resistance of the charging pile cable, thereby increasing the service life of the charging pile cable.

[0030] Furthermore, to further enhance cable performance and meet diverse application requirements, raw material diversion and double-layer extrusion technologies are employed. After mixing and degassing, the raw materials are evenly divided into two or more strands by a carefully designed diversion device. These strands then enter separate channels for double-layer or multi-layer extrusion. This double-layer extrusion structure not only increases the cable's strength and protective properties, but also allows for the selection of materials with different properties tailored to the functional requirements of the inner and outer layers. For example, the inner layer can focus on excellent conductivity and insulation, while the outer layer can prioritize properties such as wear resistance, weather resistance, and corrosion resistance.

[0031] 4. In the manufacturing method of the reinforced torsion-resistant charging pile cable, a double-layer insulation layer is extruded through the extrusion component, which not only increases the strength and protection performance of the cable, but also improves the wear resistance, weather resistance and corrosion resistance of the charging pile cable, thereby increasing the service life of the charging pile cable.

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] Example

[0045] See also Figure 1-Figure 7 As shown, the purpose of this embodiment is to provide a method for manufacturing a reinforced torsion-resistant charging pile cable, comprising the following steps:

[0046] S1. Raw material preparation: Select high-purity copper or aluminum as conductor materials, and select high-quality insulation materials;

[0047] S2. Mixed extrusion: Start the extrusion equipment to crush the raw materials first, then blend and stir the crushed raw materials, and then extrude the stirred raw materials into the second insulation layer;

[0048] S3. Quality inspection: Conduct strict inspection on the cables to check their electrical performance, mechanical performance and appearance;

[0049] In the above process, the extrusion equipment used includes a crushing shell 10, a heat preservation barrel 20 and a housing 30. Two support columns 11 are provided on both sides of the lower side of the crushing shell 10 for fixed connection with the heat preservation barrel 20. A crushing knife 12 is provided inside the heat preservation barrel 20 to crush the raw materials.

[0050] A fusion component 21 is provided inside the insulation barrel 20, flow components 22 are provided on both sides of the upper side of the insulation barrel 20, and a feeding component 23 capable of diverting the raw materials is provided on the inner wall of the lower side of the insulation barrel 20;

[0051] The fusion component 21 can stir the raw materials and rub the inner wall of the heat preservation barrel 20 to increase the temperature inside the heat preservation barrel 20 so that the raw materials are heated and fused. At the same time, the fusion component 21 cleans the inner wall of the heat preservation barrel 20.

[0052] The free-flow component 22 can change the direction of the raw material flow. At the same time, the fusion component 21 drives the free-flow component 22 to move upward, so that the gas in the raw material inside the insulation barrel 20 is discharged;

[0053] An extrusion assembly 31 capable of extruding two insulating layers is provided inside the housing 30 .

[0054] First, the specific structure of the fusion component 21 is disclosed. The fusion component 21 includes at least a rotating shaft 211. The outer wall of the rotating shaft 211 is provided with multiple groups of fusion rods 212. The multiple groups of fusion rods 212 are arranged in a circular array, and a flow rod 213 is provided at the end of each group of fusion rods 212 away from the rotating shaft 211.

[0055] Connect the motor to the power supply to make it work, and rotate the motor output shaft to drive the rotating shaft 211 to rotate, so that the fusion rod 212 and the flow rod 213 rotate at high speed, stir the raw materials, and rub the flow rod 213 against the inner wall of the insulation barrel 20 to increase the temperature inside the insulation barrel 20, so that the raw materials are heated and fused. The insulation barrel 20 also keeps the temperature warm. At the same time, the flow rod 213 also cleans the inner wall of the insulation barrel 20 to reduce the probability of raw material waste, which not only improves the work efficiency of the charging pile cable production, but also reduces the consumption of electricity, saves costs, and thus reduces economic losses.

[0056] Secondly, the specific structure of the flow assembly 22 is disclosed. The flow assembly 22 at least includes a flow plate 223. Connecting plates 224 are provided on both sides of the flow plate 223. Exhaust grooves 221 are provided on both sides above the insulation barrel 20. An elastic member 222 is provided on the upper surface of the connecting plate 224. The upper end of the elastic member 222 is fixedly connected to the inner wall of the exhaust groove 221.

[0057] When the flow-smoothing rod 213 rotates along the inner wall of the heat preservation barrel 20, the raw materials will be stirred. However, when the raw materials encounter the flow-smoothing plate 223, part of the raw materials will change the direction of flow, which is beneficial to adjust the rheological properties of the raw materials and improve the stability and efficiency of extrusion. Moreover, when the flow-smoothing rod 213 contacts the flow-smoothing plate 223, pressure is applied along the arcs on both sides of the flow-smoothing plate 223, causing the elastic member 222 to deform and contract, moving the flow-smoothing plate 223 to the inside of the exhaust groove 221. At the same time, the gas inside the heat preservation barrel 20 will flow out from both sides of the exhaust groove 221. Similarly, when the flow-smoothing rod 213 is away from the flow-smoothing plate 223, the flow-smoothing plate 223 is reset by the rebound force of the elastic member 222, reducing the temperature loss, effectively increasing the fluidity of the raw materials, and being able to timely and efficiently discharge the gas in the raw materials, ensuring the density and high quality of the final product, and greatly improving the torsion resistance of the charging pile cable production.

[0058] The specific structure of the feeding component 23 is disclosed again. The feeding component 23 at least includes a control groove 231. A two-way cylinder 232 is arranged inside the control groove 231. The piston rods at both ends of the two-way cylinder 232 are provided with feeding plates 233. A feeding groove 234 is provided on the middle side of the feeding plate 233 away from the two-way cylinder 232.

[0059] Connect the two-way cylinder 232 to the power supply to make it work, and push the feeding plate 233 to the two ends of the control groove 231 through the work of the piston rods at both ends of the two-way cylinder 232, so that the feeding groove 234 and the two openings below the insulation barrel 20 are staggered, and the two openings below the insulation barrel 20 are sealed. At this time, the raw materials can be fused; when the fusion is completed, the feeding groove 234 is aligned with the two openings below the insulation barrel 20 through the work of resetting the piston rod of the two-way cylinder 232. At this time, the fused raw materials flow to the extrusion assembly 31 by their own gravity, and the speed of the raw material flow can be controlled by the size of the reset of the two-way cylinder 232, which has the effect of feeding, which not only improves the flexibility of the extruder, but also diverts the raw materials, and assists the extrusion assembly 31 to extrude two layers of insulation, thereby increasing the strength and protection performance of the charging pile cable, thereby improving the service life of the charging pile cable.

[0060] Then the specific structure of the extrusion assembly 31 is disclosed. The extrusion assembly 31 includes at least two flow columns 311. The two openings below the heat preservation barrel 20 are fixedly connected to the tops of the two flow columns 311 respectively. A screw auger 312 is provided inside the two flow columns 311. A drainage pipe 313 is provided below the outer wall of the two flow columns 311. The drainage pipe 313 extends from one end away from the flow column 311 to the bottom of the shell 30 and is fixedly connected to a double-layer extrusion head 314.

[0061] Start the motor, and the motor output shaft rotates to drive the auger 312 to rotate, so that the raw materials diverted inside the two flow columns 311 are moved downward, so that the fused raw materials flow to the two drainage tubes 313, and flow through the two drainage tubes 313 to one layer of the double-layer extrusion head 314, and then are extruded through the double-layer extrusion head 314. This not only increases the strength and protection performance of the charging pile cable, but also improves the wear resistance, weather resistance and corrosion resistance of the charging pile cable, thereby increasing the service life of the charging pile cable.

[0062] When the feeding component 23 is in a sealed state on the insulation barrel 20, the fused raw materials will inevitably enter the interior of the control groove 231, affecting the effect of the feeding component 23. In serious cases, it will cause damage to the parts. Therefore, sealing strips 24 are provided at the upper and lower ends of the two openings below the insulation barrel 20. The improvement is that the sealing strips 24 can prevent the fused raw materials from entering the interior of the control groove 231, which not only avoids the waste of raw materials and reduces the factors affecting the production efficiency of the charging pile cable, but also improves the protection of the feeding component 23 and reduces the frequency of failure of the feeding component 23, thereby avoiding economic losses.

[0063] Taking into account that when the flow rod 213 squeezes the flow plate 223, the effect of gas outflow may be affected, the flow rod 213 is wavy. The purpose is: through the wavy shape of the flow rod 213, the position of squeezing the flow plate 223 can be staggered, the efficiency of gas outflow can be improved, and the gas in the raw material can be discharged in a timely and efficient manner, ensuring the density and high quality of the final product, thereby improving the practicality of the extruder.

[0064] In order to increase the temperature of raw material fusion, the insulation barrel 20 adopts an alloy material with good thermal conductivity and wear resistance, and the flow rod 213 adopts a polymer composite material, wherein the polymer composite material can be polyetheretherketone, which has excellent mechanical properties, high temperature resistance and chemical stability, increasing the safety of charging pile cable production, or polyphenylene sulfide, which is high temperature resistant and corrosion resistant, and also has good mechanical strength, greatly improving the yield of charging pile cable production, or polyimide, which can maintain good performance at high temperatures, and has high strength and high wear resistance; the improvement is that: the insulation barrel 20 adopts an alloy material with good thermal conductivity, and the alloy material includes tungsten-copper alloy, copper-nickel alloy, aluminum bronze and brass, and tungsten-copper alloy is preferably selected, which includes at least tungsten and copper, has high thermal conductivity, excellent electrical conductivity, good wear resistance and corrosion resistance, and can transfer the heat of the external heating source to the internal raw materials more quickly, thereby accelerating the heating process of the raw materials and improving production efficiency, and the alloy material with good wear resistance can extend the service life of the insulation barrel 20 and reduce the equipment maintenance and replacement costs caused by wear.

[0065] In summary, the working principle of this solution is as follows: first, the two-way cylinder 232 is powered on to start working. The piston rods at both ends of the two-way cylinder 232 push the feed plate 233 toward the two ends of the control groove 231, so that the feed groove 234 and the two openings below the heat preservation barrel 20 are staggered, thereby sealing the two openings below the heat preservation barrel 20;

[0066] Afterwards, the prepared raw materials are poured into the interior of the crushing shell 10, and the motor is started. The crushing blade 12 is driven by the motor to crush the raw materials, and the crushed raw materials flow into the interior of the heat preservation barrel 20. At this time, the motor is connected to the power supply to make it work, and the motor output shaft rotates to drive the rotating shaft 211 to rotate, so that the fusion rod 212 and the flow rod 213 rotate at high speed, stirring the raw materials, and the flow rod 213 rubs against the inner wall of the heat preservation barrel 20 to increase the temperature inside the heat preservation barrel 20, so that the raw materials are heated and fused. When the flow rod 213 contacts the flow plate 223, pressure is applied along the arcs on both sides of the flow plate 223, causing the elastic member 222 to deform and contract, and move the flow plate 223 to the inside of the exhaust groove 221. At the same time, the gas inside the heat preservation barrel 20 will flow out from both sides of the exhaust groove 221. When the flow rod 213 is away from the flow plate 223, the flow plate 223 is reset by the rebound force of the elastic member 222.

[0067] After the fusion is completed, the piston rod of the two-way cylinder 232 is reset to align the feed trough 234 with the two openings below the insulation barrel 20. At this time, the fused raw materials flow to the extrusion assembly 31 by their own gravity. At the same time, the motor is started and the output shaft of the motor rotates to drive the auger 312 to rotate, and the raw materials diverted inside the two flow columns 311 are moved downward, so that the fused raw materials flow to the two drainage pipes 313, and flow through the two drainage pipes 313 to one layer of the double-layer extrusion head 314 respectively, and then extrude through the double-layer extrusion head 314 to complete the extrusion of the charging pile cable.
