Description

Technical Field

[0001] The present invention relates to the field of power cables, and in particular to a system and process for preparing a crack-proof, halogen-free, low-smoke, flame-retardant power cable. Background Art

[0002] Power cables are used to transmit and distribute electrical energy. They are commonly used in urban underground power grids, power station outgoing lines, internal power supplies for industrial and mining enterprises, and underwater transmission lines across rivers and seas. The proportion of cables in power lines is gradually increasing. Power cables are used to transmit and distribute high-power electrical energy in the backbone lines of power systems. The basic structure of a power cable consists of four parts: a core, an insulation layer, a shielding layer, and a protective layer. The core is the conductive part of the power cable, used to transmit electrical energy and is the main component of the power cable. The insulation layer electrically isolates the core from the ground and between cores of different phases to ensure power transmission and is an indispensable component of the power cable structure.

The utility model realizes that the twisting angle can be adjusted as needed during the twisting process of the wires through the arrangement of structures such as the base plate, the auger disk, the shaping tube, the adjustment mechanism and the twisting mechanism. By setting the adjustment mechanism, the angles of several wires are changed synchronously, so that the angles during the twisting process are changed, thereby making it possible to manufacture different types of cables.

However, when the cables are rolled up, the cables may fall and deform due to the influence of gravity, which makes the cables not tightly rolled up, making them easy to spread out after being rolled up, affecting the collection of the cables.

[0020] The present invention also discloses a preparation process of a crack-proof halogen-free low-smoke flame-retardant power cable preparation system, which uses the above-mentioned crack-proof halogen-free low-smoke flame-retardant power cable preparation system, including the following steps:

[0021] S1. The cable insulation inner wall is placed on one side of the placement plate by setting a placement roller, and the conductor copper wire is placed on the other side of the placement plate by setting a conductor roller. Then, the cable insulation inner wall is moved through the placement plate by setting a winding mechanism, and the conductor copper wire is moved synchronously, so that the conductor copper wire passes through the first extruder, and the surface of the conductor copper wire is wrapped with low-smoke halogen-free flame-retardant polyolefin plastic;

[0022] S2. Through the arrangement of the hollow box and the through-holes, the copper wire wrapped with smoke-free halogen-retardant polyolefin plastic conductor is wound on the surface of the cabling roller. Through the cabling motor and the belt, the linkage block rotates, driving the cabling drum to rotate synchronously, thereby rotating the cabling roller. Through the arrangement of the stranding drum, the auger drum and the shaping tube, and through the mutual cooperation of the hollow tube and the shaping tube, the copper wire conductor on the surface of the cabling roller is entangled with the inner layer of the cable insulation, thereby forming a cable;

[0023] S3. After the wires are cabled, the cables are passed through the mounting ring and the rotating disk. The drive motor is set to cause the connecting gear to drive the gear ring and the rotating disk to rotate, thereby wrapping the bandage wrapped around the surface of the anti-cracking roller around the cable.

[0024] S4. The cable surface is wrapped with a synthetic sheath made of highly flame-retardant, low-smoke, halogen-free plastic and rubber by a second extruder. A water pump is used to draw water from the water tank into the connecting groove to cool the cable passing through the cooling plate. Simultaneously, the connecting groove and the circulation pipe cooperate to allow the used cooling water to re-enter the water tank.

[0025] S5. After the wires are cabled, the winding motor is set so that the driving gear drives the linkage gear to rotate, thereby causing the winding roller to rotate and the cable to be wound. The guide mechanism is set so that the cable moves back and forth inside the guide plate through the reciprocating screw rod, so that the cable moves back and forth on the winding roller to be wound.

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

[0027] 1. Through the arrangement of the conductor assembly mechanism, cabling mechanism, winding mechanism, guide mechanism, water cooling mechanism and anti-cracking mechanism, after the power wires are cabled, the cables are passed through the mounting ring and the rotating disk, and the driving motor is started, so that the connecting gear drives the gear ring to rotate inside the mounting ring, thereby causing the rotating disk to rotate synchronously, driving the two anti-cracking rollers to rotate synchronously, so that the bandages on the surface of the anti-cracking rollers are wound around the surface of the cable, so that the cable is wound more tightly during use, so that after the cable is produced, the internal wires of the cable are prevented from spreading and the sheath on the surface of the cable is squeezed, thereby preventing the cable surface from cracking, making the cable more durable during use;

[0028] 2. Through the arrangement of the conductor assembly mechanism, cabling mechanism, winding mechanism, guide mechanism, water cooling mechanism and anti-cracking mechanism, during the power cable production process, the power wires are wound around the inner surface of the insulated cable through the cabling mechanism, the adjusting motor is started to rotate the threaded rod, and the limit rod is arranged so that the threaded rod drives the adjusting disk to slide on the surface of the hollow tube, thereby adjusting the position between the adjusting disk and the auger disk, so that the angles of several wires are changed synchronously, thereby changing the angles during stranding, thereby manufacturing different types of cables, so that the cables can be applied to more different situations in subsequent use;

[0029] 3. Through the arrangement of the conductor assembly mechanism, cabling mechanism, winding mechanism, guide mechanism, water cooling mechanism and anti-cracking mechanism, after the cable surface is wrapped with a synthetic sheath made of highly flame-retardant, low-smoke and halogen-free plastic and rubber, the cable is passed through the guide groove and fixed to the winding roller, the winding motor is started, the winding roller rotates, and the cable is wound. Through the mutual cooperation of the driving rod and the belt, the reciprocating screw rod rotates synchronously, so that the reciprocating screw rod slides back and forth inside the guide groove, pushing the cable to slide synchronously inside the guide groove, so that when the cable is wound on the winding roller, the winding position moves back and forth on the winding roller, so that the cable is wound more tightly, and the mutual cooperation of the guide mechanism and the winding mechanism prevents the cable from being affected by gravity and deforming when winding.

[0030] 4. Through the arrangement of the conductor assembly mechanism, cabling mechanism, winding mechanism, guiding mechanism, water cooling mechanism and anti-cracking mechanism, the winding mechanism drives the wire to move, so that the wire passes through the arrangement of the first extruder, and the surfaces of several wires are wrapped with low-smoke halogen-free flame-retardant polyolefin plastic, which improves the flame retardant effect of the wire and reduces the toxicity of wire burning. The cabling mechanism allows several wires to be entangled with the inner lining of the insulated cable to form a cable. Afterwards, the anti-cracking mechanism cooperates with the clamping plate and other structures to make the cable winding more tightly. Through the arrangement of the second extruder, the surface of the cable is wrapped with a synthetic sheath made of highly flame-retardant, low-smoke halogen-free plastic and rubber to protect the cable, thereby making the cable safer when in use. At the same time, the produced cable is automatically wound by the winding mechanism, which facilitates the collection of the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] In this embodiment: through the setting of the through hole and the wire entry hole 306, the conductor copper wire passes through the hollow box 301 and the cable drum 305, and the conductor copper wire wrapped with low-smoke halogen-free flame-retardant polyolefin plastic is wound on the surface of the corresponding cable roller 307, and the cable insulation inner lining is synchronously passed through the hollow box 301 and the cable drum 305, and the conductor copper wire and the cable insulation inner lining are synchronously inserted into the interior of the hollow tube 310. Then, the cable motor 302 is started, and its output end drives the linkage disk 303 to rotate, so that the linkage block 304 rotates through the setting of the belt, so that the cable drum 305 rotates on the surface of the hollow tube 310, thereby driving the cable roller 307 to rotate synchronously, so that the conductor copper wire on the surface of the cable roller 307 is wound on the surface of the cable insulation inner lining, so that the conductor copper wire and the cable insulation inner lining are cabled, so that the power cable is cabled and passes through the mounting frame 308. The arrangement of the auger disc 311 and the capstan disc 309 guides and supports the conductor copper wire, making the conductor copper wire more stable when rotating;

[0054] Please refer to Figures 5 to 7 The upper surface of the preparation base plate 1 is fixedly connected with a shaping tube 8 near the auger disc 311, and the surface of the hollow tube 310 is fixedly connected with an adjusting motor 9. The output end of the adjusting motor 9 is fixedly connected with a threaded rod 10. The surface of the threaded rod 10 is threadedly connected with an adjusting disk 11 that is slidably sleeved on the surface of the hollow tube 310. The surface of the adjusting disk 11 is slidably inserted with a limiting rod 12 fixedly connected to the hollow tube 310. The adjusting disk 11 corresponds to the auger disc 311. The upper surface of the preparation base plate 1 is fixedly connected with a clamping plate 14 near the anti-cracking roller 707. A wire entry hole 15 is opened on the surface of the clamping plate 14. The two inner walls of the wire entry hole 15 are slidably connected with an arc plate 16. The outer arc surfaces of the two arc plates 16 are fixedly connected with an elastic block 17 fixedly connected to the inside of the wire entry hole 15.

[0055] In this embodiment, the cable insulation lining and the conductor copper wire are passed through the shaping tube 8 by the setting of the shaping tube 8. As a result, when the cable drum 305 and the cable roller 307 rotate, the conductor copper wire is wound around the surface of the cable insulation lining. As a result, the conductor copper wire and the cable insulation lining form a cable after passing through the shaping tube 8. At the same time, the cable is inserted into the interior of the clamping plate 14 through the wire entry hole 15. The elastic block 17 is provided so that the two arc plates 16 clamp the cable, making the cable more stable during subsequent processing.

[0056] When it is necessary to process power cables with different requirements, the adjusting motor 9 can be started so that its output end drives the threaded rod 10 to rotate. By setting the limit rod 12, the adjusting disk 11 is moved on the surface of the threaded rod 10, so that the adjusting disk 11 slides on the surface of the hollow tube 310, and the distance between the adjusting disk 11 and the auger disk 311 is adjusted, so that the adjusting disk 11 can push the position of several conductor copper wires, adjust the angle between the conductor copper wire and the auger disk 311, and the conductor copper wire slides inside the auger disk 311, so that the angle between the conductor copper wire and the shaping tube 8 is changed, so that the angle of the cabling mechanism 3 when stranding is changed, so that different types of power cables can be manufactured, so that the power cables can be applied to more different situations in subsequent use;

[0057] Please refer to Figures 1 to 8 The water cooling mechanism 6 includes a cooling plate 601 fixedly connected to the upper surface of the preparation base plate 1 and close to the mounting plate 401. A connecting groove 605 corresponding to the guide groove 502 is opened inside the cooling plate 601. A water tank 602 fixedly connected to the preparation base plate 1 is fixedly connected to one side of the cooling plate 601. A water pump 603 is fixedly connected to the upper surface of the water tank 602. The output end of the water pump 603 is fixedly connected to a drainage pipe 604 connected to the connecting groove 605. The input end of the water pump 603 is fixedly connected to a water suction pipe 606 connected to the water tank 602. A circulation pipe 607 connected to the connecting groove 605 is fixedly connected to one side of the water tank 602. A water adding pipe connected to the water tank 602 is fixedly connected to one side of the upper surface of the water tank 602. The upper surface of the preparation base plate 1 is fixedly connected to a second extruder 13 near the cooling plate 601.

[0058] In this embodiment, after the cable passes through the clamping plate 14, the second extruder 13 is set to wrap the cable surface with a synthetic sheath made of highly flame-retardant, low-smoke, and halogen-free plastic and rubber to protect the cable surface. Then, the cable is inserted into the cooling plate 601, and the water pump 603 is started so that its input end draws the cooling water in the water tank 602 into the water pump 603 through the suction pipe 606. The cooling water in the water pump 603 is discharged into the connecting groove 605 through the drainage pipe 604. The connecting groove 605 allows the cooling water to fall on the cable surface, cooling the highly flame-retardant, low-smoke, and halogen-free plastic and rubber synthetic sheath on the cable surface. Thus, the cable can achieve the effect of highly flame-retardant, low-smoke, and halogen-free when in use, making the power cable safer when in use. Moreover, the circulation pipe 607 cooperates with the connecting groove 605 to allow the used cooling water to re-enter the water tank 602 so that the cooling water can be recycled.

[0059] In combination with the above-mentioned crack-proof halogen-free low-smoke flame-retardant power cable preparation system, a preparation process of the crack-proof halogen-free low-smoke flame-retardant power cable preparation system is provided, which specifically includes the following steps:

[0060] S1. The cable insulation inner wall is placed on one side of the placement plate 201 by the placement roller 202, and the conductor copper wire is placed on the other side of the placement plate 201 by the conductor roller 204. Then, the cable insulation inner wall is moved through the placement plate 201 by the winding mechanism 4, and the conductor copper wire is moved synchronously, so that the conductor copper wire passes through the first extruder 205, and the surface of the conductor copper wire is coated with low-smoke halogen-free flame-retardant polyolefin plastic.

[0061] S2. Through the arrangement of the hollow box 301 and the through-holes, the copper wire wrapped with the smoke-free, halogen-free, flame-retardant polyolefin plastic conductor is wound on the surface of the cabling roller 307. Through the cabling motor 302 and the belt, the linkage block 304 rotates, driving the cabling drum 305 to rotate synchronously, thereby rotating the cabling roller 307. Through the arrangement of the stranding drum 309, the auger drum 311 and the shaping tube 8, and through the mutual cooperation of the hollow tube 310 and the shaping tube 8, the copper wire on the surface of the cabling roller 307 is entangled with the inner layer of the cable insulation, so that the wires are cabled;

[0062] S3. After the wires are cabled, the cables are passed through the mounting ring 703 and the rotating disk 706. The drive motor 708 is configured to cause the connecting gear 704 to drive the gear ring 705 and the rotating disk 706 to rotate, thereby wrapping the bandage wrapped around the surface of the anti-cracking roller 707 around the cable. At the same time, the curved plate 16 and the elastic block 17 cooperate with each other to clamp and smooth the cable wrapped with the bandage.

[0063] S4. The cable surface is wrapped with a synthetic sheath made of highly flame-retardant, low-smoke, halogen-free plastic and rubber by the second extruder 13. Water from the water tank 602 is pumped into the connecting groove 605 by the water pump 603 to cool the cable passing through the cooling plate 601. Simultaneously, the connecting groove 605 and the circulation pipe 607 cooperate to allow the used cooling water to re-enter the water tank 602.

[0064] S5. After the electric wires are cabled, the winding motor 406 is set to make the driving gear 405 drive the linkage gear 404 to rotate, thereby causing the winding roller 403 to rotate and rewind the cable. The guide mechanism 5 is set to make the cable move back and forth inside the guide plate 501 through the reciprocating screw rod 504, so that the cable moves back and forth on the winding roller 403 to be rewound.

[0065] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
