[0028] An adjusting mechanism 8 is arranged inside the wire passing cylinder 4 for adjusting the inlet angle of the main cable 10; The adjusting mechanism 8 includes: A plurality of adjusting rods 81, which are arranged at equal circumferential intervals on the inner wall of the wire passing cylinder 4 and are in contact with the main cable 10; A push rod 82, which is connected in a movable hole opened on the inner wall of the wire passing cylinder 4 through a third spring 83 and is used to push the push rod 82 and the adjusting rod 81 to be in contact with the main cable 10; An adjusting screw rod 85, which is threadedly connected to the wire passing cylinder 4 and is connected to one end of the adjusting rod 81 through a pull rope 84. By pulling the pull rope 84, the deflection of the adjusting rod 81 is changed; The diameter of the movable hole is larger than the diameter of the push rod 82. When the adjusting rod 81 deflects, the push rod 82 deflects synchronously in the movable hole.

[0029] Working principle: When stranding the cable, by stranding the cable layer by layer onto the main cable 10, the fastening performance of the stranded cable is improved. Therefore, by passing the first sub-cable 11 and the second sub-cable 12 through the first wire distributing disc 1 and the second wire distributing disc 2 respectively for wire distribution, and then passing the first sub-cable 11 and the second sub-cable 12 through the two stranding cylinders 3 respectively for sequential stranding, synchronous stranding is achieved, and the stranding efficiency is improved; However, when stranding, it is necessary to adjust the distance between the two wire distributing discs. To prevent the first sub-cable 11 from detaching from the guide wheel 94, at this time, by rotating the sliding rod 51 with the first thread groove 52, the second wire distributing disc 2 will be pushed to move to one side, and then the distance between the second wire distributing disc 2 and the first wire distributing disc 1 can be changed, thereby changing the angle of the first sub-cable 11 entering the stranding cylinder 3, so as to achieve adjustment and prevent the first sub-cable 11 from being broken due to force; When the angle between the first sub-cable 11 and the main cable 10 becomes larger, at this time, the supporting force of the guide wheel 94 on the first sub-cable 11 decreases. Under the action of the fourth spring 91, the guide wheel 94 is pushed upward, so that the guide wheel 94 always pushes and abuts against the first sub-cable 11 to support the first sub-cable 11 and prevent the first sub-cable 11 from detaching from the guide wheel 94 and affecting its guiding; Furthermore, when the fourth spring 91 deforms and pushes, when the guide wheel 94 is overly pushed and abuts against the first sub-cable 11, by rotating the screw rod 96, the U-shaped push rod 95 will be pushed to move at this time, and then the two upper U-shaped plates 93 will be pushed and the guide wheel 94 will be pushed downward, thereby reducing the abutting force on the first sub-cable 11, so as to prevent the first sub-cable 11 from being overly tightened and avoid breakage, and improve the smooth effect of stranding; When the stranding operation is in progress, the wire distributing disc 1 will rotate, driving the oil in the oil storage cavity to rotate. When the oil storage cavity rotates to the upper side, the oil inside will fall by gravity and be adsorbed and conducted through the adsorption slide rod 98 to the lubricating block 97 which also has the function of adsorption and conduction, and smear the outer wall of the guide wheel 94, thereby lubricating the secondary cable 11 to prevent the secondary cable 11 from directly rubbing against the stranding drum 3 during stranding. This lubrication can form a lubricating film on both surfaces, reduce the friction coefficient, reduce the wear on the surface of the wire, make the cable surface smoother, and at the same time extend the service life of the stranding drum and the equipment, reduce production costs. At the same time, due to the reduction of friction, the pulling force required during the stranding process will also be correspondingly reduced, thus reducing the energy consumption of the equipment and improving production efficiency. Moreover, by lubricating the cable, heat will be generated due to the deformation and friction of the metal wire during stranding, and the lubricating liquid can quickly carry away this heat, preventing the wire and the equipment from being damaged due to overheating. This helps to maintain the physical properties of the wire, avoid changes in the metal structure caused by high temperature, and at the same time protect the equipment and extend its service life; When rotating the slide rod 61 with the threaded groove 62 on the rotating belt, the L-shaped connecting seat 64 and the bearing 63 will be driven to move synchronously. When it moves left and right, the distance between the stranding drum 3 and the wire distributing disc 2 can be adjusted, thereby changing the angle between the secondary cable 12 and the main cable 10. The subsequent adjustment and effect are the same as above; After the secondary cable 11 and the secondary cable 12 are stranded in sequence, the spring 67 pushes the pressing plate 68 to abut against the outer wall of the secondary cable 11, squeezing and tightening it. Then the spring 74 pushes the pressing plate 75 to realize the pressing of the secondary cable 12; and when the cable rotates during stranding, it rotates relative to the pressing plate 75, thereby promoting the rotational pressing of the secondary cable 12. At the same time, after being rotationally pressed, it enters the integral cylinder 76 to realize further circularity processing and improve the regularity of the cable; Furthermore, when the angle of the main cable 10 deflects during the transmission process, it is necessary to adjust the angle of the main cable 10 to ensure that the appropriate deflection angle can make the auxiliary cable evenly twisted around the main cable according to the design requirements to avoid the situation where the twisted wires are not uniformly tight. At the same time, if the deflection angle is improperly set, the auxiliary cable may be subjected to excessive tension or friction during the twisting process, resulting in damage such as wear and breakage of the single wire surface. At this time, the push rod 82 is directly pushed by the spring three 83, and then the adjustment rod 81 is pushed toward the main cable 10 to achieve resistance to the main cable 10. When the main cable 10 deviates, the adjustment screw 85 in the opposite direction of the deviation is directly adjusted to rotate. At this time, the adjustment rod 81 will be driven to deflect through the pull rope 84, thereby changing the force on the entry angle of the main cable 10, thereby resetting the deflection angle, thereby ensuring the entry angle of the main cable 10, so as to reduce the load and wear of various components of the equipment, extend the service life of the equipment, reduce the downtime caused by equipment failure, improve production efficiency, and enable the twisting machine to run at a higher speed. Because the deflection angle is reasonable and the twisting state of the single wire is stable, the equipment can maintain a good working condition when running at high speed, thereby improving production efficiency.

[0030] The present invention provides a power cable core twisted wire splitting device. There are many methods and ways to implement the technical solution. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention. All components not specified in this embodiment can be implemented by existing technologies.
