[0101] The right twisting cylinder 3 is provided with the rounding mechanism 7, which is used for rounding the twisted secondary cable two 12;

[0102] The rounding mechanism 7 comprises:

[0103] Two U-shaped rods one 71 are symmetrically arranged on the outer wall of the twisting cylinder 3;

[0104] The U-shaped rod two 72 is connected to the outer wall of the U-shaped rod one 71;

[0105] A plurality of limiting slide rods two 73, two groups of active through U-shaped rod one 71 and U-shaped rod two 72;

[0106] Compression plate two 75, fixedly connected on two limiting slide rods two 73, and combined with the secondary cable two 12 after twisting, used for pressing the secondary cable two 12;

[0107] Spring two 74, sleeved on the outer wall of the limiting slide rod two 73, and connected with the compression plate two 75, used for pushing the compression plate two 75 to the secondary cable two 12;

[0108] The whole cylinder 76 is fixedly connected to the other end of the U-shaped rod one 71, used for whole cylinder after twisting the cable.

[0109] The inside of the wire passing cylinder 4 is provided with an adjusting mechanism 8 for adjusting the wire entering angle of the main cable 10;

[0110] The adjusting mechanism 8 comprises:

[0111] A plurality of adjusting rods 81 are circumferentially divided and arranged on the inner wall of the wire passing cylinder 4, and combined with the main cable 10;

[0112] The push rod 82 is connected in the movable hole opened in the inner wall of the wire passing cylinder 4 through the spring three 83, used for pushing the push rod 82 and the adjusting rod 81 to the main cable 10;

[0113] The adjusting screw 85 is threadedly connected on the wire passing cylinder 4, and connected with one end of the adjusting rod 81 through the pull rope 84, and the deflection of the adjusting rod 81 is changed by pulling the pull rope 84;

[0114] The movable hole diameter is greater than the push rod 82 diameter, and the push rod 82 is synchronously deflected in the movable hole when the adjusting rod 81 is deflected.

[0115] Working principle: when the cable is twisted, the cable is twisted on the main cable 10 layer by layer, which improves the fastening performance of the twisted cable, therefore, the secondary cable one 11 and the secondary cable two 12 are respectively threaded through the distribution block one 1 and the distribution block two 2 for distribution, and then the secondary cable one 11 and the secondary cable two 12 are respectively threaded through the two twisting cylinders 3 for sequential twisting, realizing synchronous twisting and improving the twisting efficiency;

[0116] But when twisting, the distance between the two distribution blocks needs to be adjusted, in order to avoid the secondary cable one 11 from being separated from the guide wheel 94, at this time the slide rod one 51 with the threaded groove one 52 is rotated, which pushes the distribution block two 2 to move to one side, thereby changing the distance between the distribution block two 2 and the distribution block one 1, so as to change the angle of the secondary cable one 11 to the twisting cylinder 3, so as to realize the adjustment and avoid the secondary cable one 11 from being broken under stress;

[0117] When the angle between the secondary cable one 11 and the main cable 10 becomes larger, the support force of the guide wheel 94 to the secondary cable one 11 decreases, and the guide wheel 94 is pushed upward under the action of the spring four 91, so that the guide wheel 94 always pushes and contacts the secondary cable one 11, supports the secondary cable one 11, and avoids the secondary cable one 11 from being separated from the guide wheel 94, thereby affecting the guidance;

[0118] Further, when the spring four 91 is deformed and pushes, the guide wheel 94 is excessively pushed to contact the secondary cable one 11, the rotating screw 96 is rotated, the U-shaped push rod 95 is pushed to move, the two U-shaped plates 93 above are pushed to move, the guide wheel 94 is pushed to move downward, the contact force on the secondary cable one 11 is reduced, the secondary cable one 11 is prevented from being excessively tightened, the breakage is avoided, the smoothness of the stranded wire is improved;

[0119] Meanwhile, when the stranded wire is performed, the distribution disc one 1 rotates, the oil in the oil storage cavity rotates, the oil in the oil storage cavity falls under the action of gravity when the oil storage cavity rotates to the upper side, is adsorbed and conducted to the lubricating block 97 which also has the adsorption and conduction function through the adsorption slide rod 98, is applied to the outer wall of the guide wheel 94, lubricates the secondary cable one 11, and avoids the secondary cable one 11 from directly rubbing the stranded wire cylinder 3 when the stranded wire is performed. The lubrication can form a lubricating film on the surfaces of the two, reduces the friction coefficient, reduces the wear of the surface of the wire, makes the surface of the cable smoother, prolongs the service life of the stranded wire cylinder and the equipment, reduces the production cost, reduces the tension required in the stranded wire process due to the reduction of friction, thereby reducing the energy consumption of the equipment, improving the production efficiency, and preventing the wire and the equipment from being damaged due to overheating by lubricating the cable, the stranded wire, and the like. This helps to maintain the physical properties of the wire, avoids the change of the metal organization due to high temperature, protects the equipment, and prolongs the service life of the equipment;

[0120] When the slide rod two 61 with the threaded groove two 62 of the rotating belt is rotated, the L-shaped connecting seat 64 and the bearing 63 are synchronously moved, the distance between the stranded wire cylinder 3 and the distribution disc two 2 is adjusted when the L-shaped connecting seat 64 and the bearing 63 are moved left and right, the angle between the secondary cable two 12 and the main cable 10 is changed, and the subsequent adjustment and effect are the same as those described above;

[0121] When the secondary cable one 11 and the secondary cable two 12 are stranded in sequence, the spring one 67 pushes the pressing plate one 68 to contact the outer wall of the secondary cable one 11, extrudes the secondary cable one 11, and then the spring two 74 pushes the pressing plate two 75 to extrude the secondary cable two 12; and when the cable is rotated and stranded, the pressing plate two 75 rotates relative to the pressing plate two 75, thereby promoting the rotation and pressing of the secondary cable two 12, and the secondary cable two 12 is rotated and pressed and then enters the rounding cylinder 76, thereby realizing further rounding processing and improving the roundness of the cable;

[0122] Further, when the main cable 10 is twisted during transmission, the angle of the main cable 10 is deflected, the angle of the main cable 10 needs to be adjusted to ensure that the appropriate deflection angle can make the secondary cable uniformly twisted around the main cable according to the design requirements, avoiding the situation that the twisted wire is tight or loose, at the same time, if the deflection angle is not properly set, the secondary cable may be subjected to excessive tension or friction during the twisting process, resulting in surface wear, breakage and other damage of the single wire, at this time, the spring 83 directly pushes the push rod 82, and then pushes the adjusting rod 81 to move towards the main cable 10, so as to realize the resistance of the main cable 10, when the main cable 10 deviates, the adjusting screw 85 in the opposite direction of the deviation is directly adjusted, at this time, the adjusting rod 81 will be deflected by the pull rope 84, and then the angle of the main cable 10 will be changed. The force of the incoming line to reset the deflection angle, so as to ensure the angle of the main cable 10, reduce the load and wear of each part of the equipment, prolong the service life of the equipment, reduce the downtime caused by equipment failure, improve the production efficiency, and make the twisting machine run at a higher speed. Because the deflection angle is reasonable, the twisting state of the single wire is stable, and the equipment can maintain good working condition when running at high speed, thereby improving the production efficiency.

[0123] The application provides a power cable core twisting and dividing device, and there are many methods and approaches to specifically realize the technical scheme. The above description is only the preferred embodiment of the application, and it should be pointed out that, for ordinary skilled in the art, some improvements and refinements can be made without departing from the principle of the application, and these improvements and refinements should also be regarded as the protection scope of the application. The components not explicitly described in the embodiment can be realized by the existing technology.
