[0002] Cables are a common material in the field of power transmission, mainly used to transmit electrical energy or control signals. Control cables are mainly used for controlling equipment. Generally, there are multiple control cables, so control cables often use multi-core cables. This requires that the core cables are twisted together with multiple strands of core wires coated with insulation layers and nylon ropes during the cabling process to form a multi-core cable. The above process is also called cabling.

[0003] In the above twisting process, it is often necessary to twist several core wires and nylon ropes of the same or different diameters together in a specific direction and rule to form an overall multi-core composite cable;

[0042] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0043] Embodiment 1: Figures 1 to 11 As shown, a cable twisting device according to an embodiment of the present invention comprises a base 1, a fixing box 2 is fixedly connected to the upper surface of the base 1, a built-in motor is arranged inside the fixing box 2, a fixing shaft 21 is fixedly connected to the output end of the built-in motor, a plurality of fixing rods 23 are fixedly connected to the circumferential surface of the fixing shaft 21, a wire wheel 22 is fixedly connected to the circumferential surface of each fixing rod 23, a positioning disk 27 is also fixedly connected to the circumferential surface of the fixing shaft 21, a plurality of fixing columns 28 are fixedly connected to one side of the positioning disk 27, and a same twisting disk 29 is fixedly connected to the side of the plurality of fixing columns 28 away from the positioning disk 27;

[0044] A spraying assembly is provided on the surface of the capstan 29, and the spraying assembly includes a first gear 32 fixedly connected to the middle part of the capstan 29, a first motor 312 is fixedly connected to the end of the fixed shaft 21 close to the capstan 29, the first motor 312 is fixedly connected to the first gear 32, the first gear 32 is meshed with a plurality of second gears 33, and a plurality of nozzles 35 are fixedly connected to the side of each second gear 33 away from the positioning plate 27, the upper surface of the base 1 is fixedly connected to the bottom plate 3, the upper surface of the bottom plate 3 is fixedly connected to the fixing ring 31, the fixing ring 31 is rotatably connected to the capstan 29, a connecting pipe 38 is fixedly connected to the circumferential surface of the fixing ring 31, the upper surface of the base 1 is fixedly connected to the fixing table 4, the upper surface of the fixing table 4 is fixedly connected to the storage box 39, the storage box 39 is fixedly connected to the connecting pipe 38, and the upper surface of the storage box 39 is fixedly connected to the pressure pump 311.

[0045] Specifically, there is still a certain gap when twisting the nylon rope and the wire. When there is a large gap, the nylon rope and the wire may move relative to each other when the cable is bent or subjected to external force, thereby increasing the risk of wear and damage.

[0046] Therefore, the present invention solves this problem by setting a certain structure. First, after the wire wheel 22 is inserted into the fixing rod 23, the first screw 26 is screwed into the thread groove 25 at the top of the fixing rod 23, so that the cable is clamped between the chassis 24 and the first screw 26, thereby achieving the effect of fixing the wire wheel 22 and facilitating the installation and removal of the wire wheel 22. After several wire wheels 22 are fixed on the circumferential surface of the fixing shaft 21, the wire and nylon rope on the wire wheel 22 are passed through the twisting disk 29, and the wire and nylon rope passing through the twisting disk 29 are fixed by the traction machine. After the fixing is completed, the built-in motor in the fixing box 2 is started, and the built-in motor drives the fixing shaft 21 to rotate. The rotation of the fixing shaft 21 drives the twisting disk 29 to rotate, and the twisting disk 29 twists the wire and nylon rope into a cable. During the twisting process, the first motor 312 of the fixing shaft 21 close to one end of the twisting disk 29 is started, and the first motor 312 can drive the first gear 32 to rotate. The wheel 32 drives the plurality of second gears 33 meshing therewith to rotate. The second gears 33 rotate and the pressure pump 311 is started. The pressure pump 311 pressurizes the colloid in the storage box 39 into the second cavity 37 inside the twisting disk 29, and sprays it out from the nozzle 35 on one side of each second gear 33. The sprayed colloid adheres to the surface of the nylon rope and the conductor, and then the nylon rope and the conductor are twisted more tightly, so that the gap between the nylon rope and the conductor is eliminated by the colloid, thereby increasing the contact area between the nylon rope and the conductor and improving the twisting strength.

[0047] The problem that a certain gap still exists in the existing process of twisting the nylon rope and the conductor is solved. When there is a large gap, the nylon rope and the conductor may move relative to each other when the cable is bent or subjected to external force, thereby increasing the risk of wear and damage.

[0048] like Figure 7 As shown, in this embodiment, a first cavity 36 is opened inside each second gear 33 on a side close to the nozzle 35 , and a second cavity 37 is opened inside the twisting disk 29 . The second cavity 37 is connected to the first cavity 36 of each second gear 33 .

[0049] Specifically, the pressure pump 311 pressurizes the colloid, and the colloid enters the second cavity 37 inside the twisting disk 29 along the connecting pipe 38, and then flows into the first cavity 36 inside each second gear 33 under pressure, and finally is sprayed out from the nozzle 35 on one side of the second gear 33, thereby achieving the effect of spraying the wire and the nylon rope at the same time.

[0050] like Figure 6 As shown, in this embodiment, a plurality of cleaning rods 34 are fixedly connected to the inner wall of each second gear 33 close to the positioning plate 27, and the plurality of cleaning rods 34 are used to clean the surface of the conductor and the nylon rope.

[0051] Specifically, during the rotation of the second gear 33, the cleaning rod 34 fixed to the inner wall of the side close to the positioning plate 27 rotates accordingly, contacts the surface of the passing wire and nylon rope, realizes the cleaning effect, can effectively remove impurities on the wire and nylon rope, and improves the twisting quality.

[0052] like Figure 5 As shown, a threaded cover 310 is threadedly connected to the upper surface of the storage box 39 in this embodiment.

[0053] Specifically, by rotating the threaded cover 310, it can be tightly connected or separated from the upper surface of the storage box 39, thereby sealing or filling the colloid in the storage box 39, making it convenient to replenish the colloid at any time, while ensuring that the storage box 39 can effectively prevent the colloid from volatilizing or being contaminated when not in use.

[0054] like Figure 3 As shown, in this embodiment, a base plate 24 is fixedly connected to the circumferential surface of the fixing rod 23 , a thread groove 25 is formed at the top end of the fixing rod 23 , and a first screw rod 26 is threadedly connected to the inner thread of the thread groove 25 .

[0055] Specifically, after the wire wheel 22 is inserted into the fixing rod 23, the first screw 26 is screwed into the threaded groove 25 at the top of the fixing rod 23, so that the cable is clamped between the chassis 24 and the first screw 26, thereby achieving the effect of fixing the wire wheel 22 and facilitating the installation and removal of the wire wheel 22.

[0056] Embodiment 2: Figures 1 to 11 As shown, compared with Example 1, another embodiment of the present invention is: a second motor 5 is arranged on the upper surface of the base 1, and the output end of the second motor 5 is fixedly connected to the first rotating wheel 51, the first rotating wheel 51 is drivingly connected to the first strip steel 52, the end of the first strip steel 52 away from the first rotating wheel 51 is drivingly connected to the second rotating wheel 53, the middle part of the second rotating wheel 53 is fixedly connected to a reciprocating screw 54, the lower surface of the storage box 39 is fixedly connected to a limiting block 55, the limiting block 55 is rotatably connected to the reciprocating screw 54, the limiting block 55 is used to limit the reciprocating screw 54, one end of the reciprocating screw 54 is fixedly connected to a rotating gear 511, the rotating gear 511 is meshed with an auxiliary gear 512, the auxiliary gear 512 is rotatably connected to one side of the fixed platform 4, the inner wall of the auxiliary gear 512 is fixedly connected to a plurality of positioning blocks 513, and a coating roller 514 is rotatably connected between every two positioning blocks 513.

[0057] Specifically, after the stranding disk 29 is stranded, the second motor 5 is started, and its output end drives the first rotating wheel 51 to rotate. The first rotating wheel 51 drives the first steel strip 52 to transmit through the transmission connection. The other end of the first steel strip 52 is connected to the second rotating wheel 53. Therefore, the movement of the first steel strip 52 will drive the second rotating wheel 53 to rotate. The middle part of the second rotating wheel 53 is fixedly connected to the reciprocating screw 54. As the second rotating wheel 53 rotates, the reciprocating screw 54 rotates under the limit of the limit block 55. One end of the reciprocating screw 54 is fixedly connected to the rotating gear 511. The rotating gear 511 is meshed with the auxiliary gear 512. Therefore, when the reciprocating screw 5 When the auxiliary gear 512 rotates, it will drive the auxiliary gear 512 to rotate synchronously. The inner wall of the auxiliary gear 512 is fixed with a plurality of positioning blocks 513. A coating roller 514 is rotatably connected between every two positioning blocks 513. As the auxiliary gear 512 rotates, the coating roller 514 rotates with the support of the positioning blocks 513, thereby realizing uniform coating of the colloid extruded from the circumferential surface of the twisted cable, realizing automatic coating of the colloid, and greatly improving production efficiency. At the same time, the rotation of the reciprocating screw 54 enables the coating roller 514 to evenly apply the colloid to the circumferential surface of the twisted cable, thereby improving the twisting quality of the cable.

[0058] like Fig. 9 As shown, the circumferential surface of the reciprocating screw 54 of this embodiment is slidably connected to a sliding rod 56, a piston rod 57 is fixedly connected to one side of the sliding rod 56, a piston tube 58 is fixedly connected to the position of the fixed platform 4 corresponding to the piston rod 57, the piston rod 57 is plugged into the piston tube 58, a positioning ring 59 is fixedly connected to one side of the piston tube 58, and a plurality of nozzles 510 are opened on the inner wall of the positioning ring 59, and the plurality of nozzles 510 are used for rapid solidification of the colloid.

[0059] Specifically, as the reciprocating screw 54 rotates, the slide bar 56 sliding on its circumferential surface also reciprocates accordingly. One side of the slide bar 56 is fixedly connected to the piston rod 57. When the slide bar 56 moves, the piston rod 57 is inserted in the piston tube 58, thereby changing the volume of the internal space of the piston tube 58. One side of the piston tube 58 is fixedly connected to the positioning ring 59. The inner wall of the positioning ring 59 is provided with a plurality of nozzles 510. When the piston rod 57 moves toward the inside of the piston tube 58, the pressure in the piston tube 58 increases, and air is ejected through the nozzles 510, thereby realizing rapid solidification of the colloid after coating.

[0060] like Fig. 9 As shown, in this embodiment, a piston cavity 515 is opened in the piston tube 58, and a rotating plate 516 is rotatably connected to the inner wall of the piston cavity 515.

[0061] Specifically, a rotating plate 516 is rotatably connected to the inner wall of the piston cavity 515. When the piston rod 57 is inserted into the piston tube 58, the rotating plate 516 is in a closed state, and the air will be squeezed into the positioning ring 59, and then sprayed out from the nozzle 510. Then, when the piston rod 57 is pulled out of the piston tube 58, the internal pressure of the piston cavity 515 decreases, and the external atmospheric pressure squeezes the rotating plate 516, allowing the external gas to enter the piston cavity 515, thereby achieving the effect of balancing the internal and external pressures of the piston tube 58, and timely replenishing the gas in the piston tube 58.

[0062] like Fig.10 As shown, in this embodiment, a clamping plate 63 is fixedly connected to one side of the fixed platform 4 close to the auxiliary gear 512, and a collecting box 6 is clamped on the surface of the clamping plate 63. A clamping groove 62 is provided at the position of the collecting box 6 corresponding to the clamping plate 63, and a collecting groove 61 is provided inside the collecting box 6.

[0063] Specifically, the clamping plate 63 is fixed to the fixed platform 4 and engaged with the clamping slot 62 of the collecting box 6 to ensure that the collecting box 6 is stable. When the coating roller 514 is rotating and coating, the dripping colloid falls into the collecting slot 61, effectively collecting the excess colloid, avoiding waste and pollution of the environment, and facilitating subsequent processing and reuse.

[0064] Embodiment 3: A cable twisting method of a cable twisting device, specifically comprising:

[0065] Step 1: Preparation: First, fix a plurality of wire wheels 22 on the circumferential surface of the fixed shaft 21, and then pass the wires and nylon ropes on the wire wheels 22 through the twisting disk 29, and use a traction machine to fix the wires and nylon ropes passing through the twisting disk 29;

[0066] Step 2: twisting: start the built-in motor in the fixed box 2, the built-in motor drives the fixed shaft 21 to rotate, the rotation of the fixed shaft 21 drives the twisting disk 29 to rotate, the twisting disk 29 twists the wire and the nylon rope into a cable, during the twisting process, start the first motor 312 of the fixed shaft 21 close to one end of the twisting disk 29, the first motor 312 can drive the first gear 32 to rotate, the first gear 32 drives a plurality of second gears 33 meshing therewith to rotate, the second gear 33 rotates and starts the pressure pump 311, the pressure pump 311 pressurizes the colloid in the storage box 39 into the second cavity 37 inside the twisting disk 29, flows into the first cavity 36 of each second gear 33 through the second cavity 37, and then sprays out from the nozzle 35 on one side of each second gear 33, the sprayed colloid adheres to the surface of the nylon rope and the wire;

[0067] Step 3: After twisting, the cables are rolled up.

[0068] Working principle, firstly, after the wire wheel 22 is inserted into the fixing rod 23, the first screw 26 is screwed into the thread groove 25 at the top of the fixing rod 23, so that the cable is clamped between the chassis 24 and the first screw 26, thereby achieving the effect of fixing the wire wheel 22 and facilitating the installation and removal of the wire wheel 22. After several wire wheels 22 are fixed on the circumferential surface of the fixing shaft 21, the wire and nylon rope on the wire wheel 22 are passed through the twisting disk 29, and the wire and nylon rope passing through the twisting disk 29 are fixed by the traction machine. After the fixing is completed, the built-in motor in the fixing box 2 is started, and the built-in motor drives the fixing shaft 21 to rotate. The rotation of the fixing shaft 21 drives the twisting disk 29 to rotate, and the twisting disk 29 twists the wire and the nylon rope into a cable. During the twisting process, the first motor 312 at one end of the fixing shaft 21 close to the twisting disk 29 is started, and the first motor 312 can drive the first gear 32 to rotate, and the first gear 32 drives several second gears meshing with it. 33 rotates, and the pressure pump 311 is started while the second gear 33 rotates. The pressure pump 311 pressurizes the colloid, and the colloid enters the second cavity 37 inside the twisting disk 29 along the connecting pipe 38, and then flows into the first cavity 36 inside each second gear 33 under pressure, and finally sprays out from the nozzle 35 on one side of each second gear 33. The sprayed colloid adheres to the surface of the nylon rope and the wire, and then the nylon rope and the wire are twisted more tightly, so that the gap between the nylon rope and the wire is eliminated by the colloid, thereby increasing the contact area between the nylon rope and the wire and improving the twisting strength;

[0069] During the rotation of the second gear 33, the cleaning rod 34 fixed to the inner wall of the side close to the positioning plate 27 rotates accordingly, and contacts with the surface of the wire and nylon rope passing by, so as to achieve a cleaning effect, effectively remove impurities on the wire and nylon rope, and improve the twisting quality;

[0070] After the stranding disk 29 is stranded, the second motor 5 is started, and its output end drives the first rotating wheel 51 to rotate. The first rotating wheel 51 drives the first steel strip 52 to transmit through the transmission connection. The other end of the first steel strip 52 is connected to the second rotating wheel 53. Therefore, the movement of the first steel strip 52 will drive the second rotating wheel 53 to rotate. The middle part of the second rotating wheel 53 is fixedly connected to the reciprocating screw 54. As the second rotating wheel 53 rotates, the reciprocating screw 54 rotates under the limit of the limit block 55. One end of the reciprocating screw 54 is fixedly connected to the rotating gear 511. The rotating gear 511 is meshed with the auxiliary gear 512. Therefore, when the reciprocating screw 54 rotates When the auxiliary gear 512 is moved, it will drive the auxiliary gear 512 to rotate synchronously. The inner wall of the auxiliary gear 512 is fixed with a plurality of positioning blocks 513. A coating roller 514 is rotatably connected between every two positioning blocks 513. As the auxiliary gear 512 rotates, the coating roller 514 rotates with the support of the positioning blocks 513, thereby realizing uniform coating of the colloid extruded from the circumferential surface of the twisted cable, realizing automatic coating of the colloid, and greatly improving production efficiency. At the same time, the rotation of the reciprocating screw 54 enables the coating roller 514 to evenly apply the colloid to the circumferential surface of the twisted cable, thereby improving the twisting quality of the cable.

[0071] At the same time, as the reciprocating screw 54 rotates, the slide bar 56 sliding on its circumferential surface also reciprocates accordingly. One side of the slide bar 56 is fixedly connected to the piston rod 57. When the slide bar 56 moves, the piston rod 57 performs plugging movement in the piston tube 58, thereby changing the volume of the internal space of the piston tube 58. One side of the piston tube 58 is fixedly connected to the positioning ring 59. The inner wall of the positioning ring 59 is provided with a plurality of nozzles 510. When the piston rod 57 moves into the piston tube 58, the pressure in the piston tube 58 increases, and air is ejected through the nozzles 510, thereby realizing the rapid solidification of the colloid after coating.

[0072] In addition, the clamping plate 63 is fixed to the fixing table 4 and is engaged with the clamping slot 62 of the collecting box 6 to ensure that the collecting box 6 is stable. When the coating roller 514 is rotating and coating, the dripping colloid falls into the collecting slot 61, effectively collecting the excess colloid, avoiding waste and pollution of the environment, and facilitating subsequent processing and reuse.

[0073] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
