Description

Technical Field

[0001] This invention relates to a processing system for cables used in new energy electric vehicles, belonging to the field of cable processing technology. Background Technology

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information, and realize the conversion of electromagnetic energy. In a broad sense, wires and cables are also simply referred to as cables. In a narrow sense, cables refer to insulated cables, which can be defined as: an assembly consisting of one or more insulated cores, and their respective possible covering layers, overall protective layer, and outer sheath.

[0003] The outer protective layer of wires and cables is also known as the outer protective sleeve. Existing silicone rubber extrusion production lines mainly include equipment such as wire feeding, front traction, extruder, vulcanization pipe, rear traction, and wire take-up. They usually adopt the overhead conveyor vulcanization tube vulcanization process and the horizontal hot drying tunnel vulcanization process. However, since the silicone rubber vulcanization and setting time is about 2 minutes, and during this period, the cable cannot be supported by the wire guide rollers, and the length from the die head to the setting end is about 10 meters, without the support of the wire guide rollers, the excessively long cable will not only sag due to its own weight, but also cause the cable to shake due to the instability of traction, resulting in poor cable forming quality. Summary of the Invention

[0004] The purpose of this invention is to provide a processing system for cables used in new energy electric vehicles. This vertical production line ensures that the rubber, which is in a thermoplastic state and has low hardness after extrusion, will not become eccentric on the conductor due to gravity because the conductor of the cable is in a horizontal state, thereby improving the forming quality of the cable.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a processing system for cables for new energy electric vehicles, comprising a wire feeding reel, a first traction machine, an oven, an extruder, a vulcanizing device, a second traction machine, and a take-up reel installed in sequence. The vulcanizing device includes an upward vulcanizing section, a downward vulcanizing section, and a reversing wheel. The upward vulcanizing section and the downward vulcanizing section are arranged in parallel and vertically.

[0006] The reversing wheel is located above the upward vulcanizing section and the downward vulcanizing section. The shortest distance between the parallel segments of the cable passing through the upward vulcanizing section and the downward vulcanizing section is the first length. The diameter of the reversing wheel is the same as the first length. The pay-off reel and the take-up reel are installed side by side on the ground and correspond to the upward vulcanizing section and the downward vulcanizing section respectively. A guide wheel is installed directly below the upward vulcanizing section and the downward vulcanizing section. The extruder is installed between the upward vulcanizing section and its corresponding guide wheel. The drying oven is installed between the first traction machine and its corresponding guide wheel.

[0007] Both the upward vulcanizing section and the downward vulcanizing section include at least two vulcanizing tubes, and there is a gap between two adjacent vulcanizing tubes in the upward vulcanizing section or the downward vulcanizing section. Each vulcanizing tube further includes two vulcanizing tube units. These two vulcanizing tube units are connected together and have vulcanizing cavities on the connecting side. These two vulcanizing cavities form a vulcanizing through hole for cables to pass through. A transparent tube is installed at the gap and communicates with the two vulcanizing through holes on both sides of the gap. At least one vulcanizing tube unit of a vulcanizing tube is mounted on a frame or wall by a cylinder, and the cylinder is mounted on the side of the vulcanizing tube unit away from the vulcanizing cavity.

[0008] A preheater is installed between the upward vulcanization section and the extruder. The preheater includes an insulating tube, a spiral copper tube coil, and a cooling tube. The inner diameter of the insulating tube is larger than the outer diameter of the cable. The spiral copper tube coil is wound around the outer circumference of the insulating tube and electrically connected to a high-frequency power supply. The cooling tube is wound around the outer circumference of the insulating tube and connected to a water-cooling box.

[0009] A vertical wire storage frame is installed between the second traction machine and the take-up reel. The vertical wire storage frame includes a pole, a first wire storage wheel and a second wire storage wheel. The first wire storage wheel is mounted on the pole by a bracket, and the second wire storage wheel is mounted on the pole by a sliding frame. A spark tester, a printing machine and an electrostatic powder coating machine are installed sequentially between the vertical wire storage frame and the take-up reel.

[0010] The following are further improvements to the above technical solution:

[0011] 1. In the above scheme, a baffle plate is installed at the bottom of the upward vulcanization section, and a through hole for the cable to pass through is opened in the center of the baffle plate.

[0012] 2. In the above scheme, a diameter measuring instrument is installed between the extruder and the upward vulcanization section.

[0013] 3. In the above scheme, the diameter measuring instrument is installed between the extruder and the preheater.

[0014] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0015] 1. The present invention relates to a processing system for cables used in new energy electric vehicles. Its vulcanization device includes an upward vulcanization section, a downward vulcanization section, and a reversing wheel. By dividing the vulcanization device into vertically arranged upward and downward vulcanization sections, the rubber, which is in a thermoplastic state and has low hardness after extrusion, will not experience eccentricity on the conductor due to gravity, as is common in traditional horizontal production lines where the conductor is horizontal. This prevents the rubber from affecting the cable's manufacturing quality and reducing the defect rate. Simultaneously, it solves the vibration problem caused by the lack of supporting guide wheels in the first two vulcanization sections of horizontal production lines. By using segmented upward and downward vulcanizing sections in conjunction with parallel cable reels and take-up reels on the ground, the vertical space occupied by the vulcanizing device is reduced, thus lowering the difficulty of installation and operation. This also allows for a more organized layout of other equipment, facilitating cable feeding and take-up operations from the same location, reducing manual labor and improving processing efficiency. Furthermore, by setting the diameter of the reversing wheel to be the same as the shortest distance between the two parallel sections of the cable, the cable can be reversed at the top of the upward and downward vulcanizing sections. Increasing the diameter of the reversing wheel reduces the stress on the cable during reversal, thereby minimizing its impact on the size and shape of the initially vulcanized cable and improving cable quality.

[0016] 2. The processing system for cables used in new energy electric vehicles of the present invention includes at least two vulcanizing tubes in both the upward and downward vulcanizing sections, and a gap exists between adjacent vulcanizing tubes in either the upward or downward vulcanizing section. Each vulcanizing tube further includes two vulcanizing tube units, which are connected together and have vulcanizing cavities on the connecting side. These two vulcanizing cavities form a vulcanizing through-hole for the cable to pass through. At least one vulcanizing tube unit of one of the vulcanizing tubes is mounted on a frame or wall by a cylinder. On the one hand, vertically oriented cables will not sag horizontally. Since there is no need to provide space for sag, the diameter of the vulcanizing through-hole can be significantly reduced, thereby reducing the space required for heating the vulcanizing tube and significantly improving its heating efficiency. This effectively improves processing efficiency while reducing production energy consumption. On the other hand, by disassembling the upward or downward vulcanizing section... The vulcanizing tubes, arranged in multiple intervals, allow for temperature control based on the varying vulcanization states at different locations, improving overall vulcanization quality and efficiency. The gaps also facilitate observation of the rubber's vulcanization status, simplifying operation and maintenance. Heat from the lower vulcanizing tubes is transferred to the upper tubes with rising hot air, further reducing energy consumption and improving energy efficiency. Furthermore, the cylinder-driven vulcanizing tube units can be fully opened for easy cable threading, or, after threading, only the bottom section of the upper vulcanizing segment can be opened for start-up testing, appearance, and structural inspection. During shutdown and reel replacement, the fully opened vulcanizing tubes quickly dissipate heat from the vulcanizing unit, preventing excessive cross-linking of the rubber and conductor oxidation, thus improving cable quality.

[0017] 3. The processing system for cables used in new energy electric vehicles of the present invention includes a preheater installed between the upper vulcanization section and the extruder. This preheater includes a water cooling system, an insulating tube, a spiral copper coil, and a cooling tube. The inner diameter of the insulating tube is larger than the outer diameter of the cable. The spiral copper coil is wound around the outer circumference of the insulating tube and electrically connected to a high-frequency power supply. By passing a high-frequency current converted from direct current into the copper coil, an alternating electromagnetic field is generated when the coil passes through the copper coil. When the magnetic lines of force of the electromagnetic field pass through the conductor of the metal material, a strong eddy current is generated, causing the conductor of the metal material to heat up rapidly. This achieves individual heating of the conductor. After the heated conductor and rubber enter the upper vulcanization section, the vulcanization tube heats the rubber from the outside to the inside, and the high-temperature conductor heats the rubber from the inside to the outside. This synchronizes the vulcanization speed and cross-linking degree of the inner and outer layers of the rubber, thereby reducing the stress difference between the inner and outer layers after the rubber vulcanization and cross-linking are completed. This prevents the insulation layer from cracking due to a large amount of internal stress during cable molding and use, thus affecting its service life and improving the quality of the cable.

[0018] 4. The processing system for cables used in new energy electric vehicles of the present invention includes a vertical cable storage rack installed between the second traction machine and the take-up reel. This vertical cable storage rack includes a vertical pole, a first cable storage wheel, and a second cable storage wheel. Through the cooperation of the first and second cable storage wheels in the vertical cable storage rack, the cable on the vertical cable storage rack can continue to store the cable pulled out by the second traction machine even after the cable on the vertical cable storage rack is disconnected from the take-up reel. This avoids the need for machine shutdown due to reel replacement or problems with the equipment behind the vertical cable storage rack, which would affect the cable processing efficiency. The extruder is installed in the upward vulcanization section and its corresponding guide. Between the guide rollers, by installing the extruder between the upward vulcanization section and its corresponding guide roller, the stress of the guide rollers when reversing the cable is avoided from affecting the size and shape of the rubber extruded onto the conductor, thus damaging the cable molding. The oven is installed between the first traction machine and its corresponding guide roller. Before extruding the rubber, the conductor is preheated by the oven installed in front of the guide roller. This not only removes impurities such as moisture and oil from the conductor surface and reduces the bulging problem of the cable in the vulcanization device, but also avoids excessive temperature difference between the conductor and rubber during rubber extrusion, which would affect the molding quality of the rubber on the conductor surface.

[0019] 5. The processing system for cables used in new energy electric vehicles of this invention includes a transparent tube installed at the gap. This transparent tube is connected to two vulcanization through holes on both sides of the gap. The addition of the transparent tube does not obstruct the operator's observation of the cable vulcanization process through the gap, and it also guides the heat generated in the lower vulcanization tube to rise, improving its utilization rate. Two driven wheels are installed at the gap of the lower vulcanization section. These two driven wheels are clamped on both sides of the cable and have no pressure contact with the cable. The driven wheels at the lower vulcanization section stabilize the cable routing, improve the overall processing quality of the cable, and at this time, the rubber on the cable has almost completed vulcanization and cross-linking. The pressureless contact of the driven wheels will not affect its size and shape. A baffle plate is installed at the bottom of the upper vulcanization section. The baffle plate installed below the vulcanization through holes collects impurities that precipitate onto the inner wall of the vulcanization tube during the vulcanization of the cable in the upper vulcanization section, preventing impurities from falling onto the equipment below the upper vulcanization section and affecting the normal operation of these devices.

[0044] When using the above-mentioned processing system for cables for new energy electric vehicles, by dividing the vulcanization device into vertically arranged upward vulcanization sections and downward vulcanization sections, the rubber, which is in a thermoplastic state and has low hardness after extrusion, will not experience eccentricity on the conductor due to gravity, as is the case in traditional horizontal production lines where the conductor of the cable is horizontal. This prevents the rubber from affecting the quality of cable production and reduces the defect rate of finished products. At the same time, it solves the vibration problem caused by the lack of support guide rollers in the first two sections of the vulcanization pipe in horizontal production lines.

[0045] By using segmented upward and downward vulcanizing sections in conjunction with parallel cable reels and take-up reels on the ground, the vertical space occupied by the vulcanizing device is reduced, thus lowering the difficulty of installation and operation. This also allows for a more organized layout of other equipment, enabling workers to perform cable feeding and take-up operations from the same location, reducing manual labor and improving processing efficiency. Furthermore, by setting the diameter of the reversing wheel to be the same as the shortest distance between the two parallel parts of the cable, the cable at the top of the upward and downward vulcanizing sections can be reversed. Increasing the diameter of the reversing wheel reduces the stress on the cable during reversal, thereby minimizing its impact on the size and shape of the cable after initial vulcanization and improving cable quality.

[0046] Furthermore, on the one hand, vertically oriented cables do not produce horizontal sags. Since there is no need to provide space for sags, the diameter of the vulcanizing through-holes can be significantly reduced, thereby decreasing the space required for heating the vulcanizing tubes and greatly improving heating efficiency. This effectively increases processing efficiency while reducing production energy consumption. On the other hand, by dividing the upward or downward vulcanizing section into multiple vulcanizing tubes with intervals, the heating temperature of different vulcanizing tubes can be controlled and adjusted according to the different vulcanization states at different locations to improve the overall vulcanization quality and efficiency of the cable. Additionally, the vulcanization state of the rubber can be observed through the gaps. This design facilitates debugging and operation by staff, and the heat in the lower vulcanizing tube can be transferred to the upper vulcanizing tube with the rising hot air, further reducing energy consumption and improving energy efficiency. In addition, the vulcanizing tube unit is driven by a cylinder, allowing the vulcanizing tube to be in an open state. It can be fully opened for easy wire threading, or after threading, only the bottom section of the upper vulcanizing section can be opened for easy start-up debugging, appearance and structural inspection. When changing reels and wiring during shutdown, the fully opened vulcanizing tube can quickly dissipate the heat at the vulcanizing device, preventing excessive cross-linking of the rubber and oxidation of the conductor in the vulcanizing tube, thereby improving cable quality.

[0047] In addition, by passing a high-frequency current converted from direct current into the spiral copper tube coil, the alternating electromagnetic field generated when the coil passes through the coil generates strong eddy currents when the magnetic lines of force pass through the conductor of the metal material, causing the conductor to heat up rapidly on its own. This achieves individual heating of the conductor. After the conductor and rubber enter the upward vulcanization section, the vulcanization tube heats the rubber from the outside in, while the high-temperature conductor heats the rubber from the inside out. This synchronizes the vulcanization speed and cross-linking degree of the inner and outer layers of the rubber, thereby reducing the stress difference between the inner and outer layers after the rubber vulcanization and cross-linking are completed. This prevents the insulation layer from cracking due to excessive internal stress during cable molding and use, thus affecting its service life and improving cable quality.

[0048] Furthermore, the cooperation of the first and second wire storage wheels in the vertical wire storage rack allows the rack to continue storing cables pulled out by the second traction machine even after the cables are disconnected from the take-up reel. This avoids the need for machine shutdowns due to reel changes or problems with equipment behind the rack, thus improving cable processing efficiency. By installing the extruder between the upward vulcanization section and its corresponding guide wheel, the stress from the guide wheel reversing the cable direction is prevented from affecting the size and shape of the rubber extruded onto the conductor, thus preventing damage to cable forming. Before extruding the rubber, preheating the conductor in an oven installed in front of the guide wheel not only eliminates moisture, oil, and other impurities on the conductor surface, reducing bulging issues in the vulcanization unit, but also prevents excessive temperature differences between the conductor and rubber during extrusion, which could affect the quality of rubber forming on the conductor surface.

[0049] In addition, the addition of a transparent tube not only does not obstruct workers from observing the cable vulcanization process through the gap, but also guides the heat generated in the lower vulcanization tube upward, improving its utilization rate. The driven wheel set at the lower vulcanization section stabilizes the cable routing, improving the overall processing quality of the cable. At this point, the rubber on the cable is almost completely vulcanized and cross-linked, and the pressureless contact of the driven wheel will not affect its size and shape. The baffle plate installed below the vulcanization through hole collects impurities that precipitate onto the inner wall of the vulcanization tube during the upper vulcanization section, preventing impurities from falling onto the equipment below the upper vulcanization section and affecting the normal operation of these devices.
