Description

Technical Field

[0001] The utility model relates to the technical field of wire splitting equipment of a stranding machine, and particularly relates to a lead wire structure of a stranding machine. Background Technique

[0002] A stranding machine is a mechanical device widely used in the stranding of various soft / hard conductor wires and electronic wires. It twists multiple single-conductor wires into one strand. During the operation of the stranding machine, the stranding disks rotate and rub against each other to tightly strand multiple wires together, which can enhance the mechanical strength of the cable. At the same time, it improves its electrical performance and anti-interference ability.

[0003] When stranding multiple cables, the cables will pass through multiple rotatable wire disks for twisting. For example, the Chinese utility model patent with the publication number CN210296037U: a lead wire disk of a copper wire stranding machine. This application can buffer the copper wire on the lead wire wheel through the buffer spring arranged at the lower end of the rotating shaft, thus effectively avoiding the situation that the copper wire breaks due to excessive pulling force. At the same time, through the cooperation of the telescopic spring and the U-shaped block, this application can not only limit the copper wire again, but also support the copper wire between the first wire disk and the second wire disk to avoid the copper wire between the two from becoming loose or collapsing. However, after a certain period of use, the springs cooperating with the lead wire wheel and the U-shaped block will have reduced spring force due to metal fatigue, resulting in different positions of multiple lead wire wheels and U-shaped blocks after being pressed, which will affect the guiding and output of the cable. In addition, the structural setting in this application requires replacing the spring, reducing the maintenance efficiency of the equipment. Moreover, when the cable passes through the through-tube in the second wire disk and the rubber hose, since the cable is transported from the first wire disk to the second wire disk and passes through the second wire disk, a certain angular change in the guiding will occur, resulting in continuous friction between the cable and the rubber hose, accelerating the damage progress of the rubber hose. As a result, the cable will directly rub against the through-tube from the damaged part of the rubber hose without timely maintenance of the rubber hose, causing the cable to be damaged by skinning.

A plurality of second wire wheels 10 are movably installed between the first mounting ring 8 and the second mounting ring 9. A plurality of balls 11 are movably installed at both ends of the second wire wheel 10.

[0024] As Figure 2 shown, a plurality of first mounting grooves 13 are opened on one side of the stranding eye plate 3. Eye holes 14 are opened on the inner sides of the first mounting grooves 13. The first mounting grooves 13 and the eye holes 14 opened in the stranding eye plate 3 can enable the combination of the first mounting ring 8 and the second mounting ring 9 to penetrate and be fixedly installed in the stranding eye plate 3;

[0025] As Figure 1 , Figures 3-4As shown in the figure, two limiting side plates 15 are fixedly installed on both sides of the installation cover 28. A fixing seat 16 is fixedly installed at the center of the top of the installation cover 28. The installation cover 28 is inserted and installed in the U-shaped groove 12 through the two limiting side plates 15 on both sides. A rotating block 17 is fixedly installed at the bottom of the adjusting screw rod 6. An installation seat 18 is inserted and installed on the outer side of the adjusting screw rod 6. A gasket 19 is inserted and installed on the adjusting screw rod 6 above the installation seat 18 and is limited by a nut. A compression spring 20 is sleeved on the adjusting screw rod 6 between the installation seat 18 and the gasket 19. The bottom of the adjusting screw rod 6 is rotationally installed in the fixing seat 16 through the rotating block 17. The installation seat 18 is fixedly installed on the outer side of the wire spool 2 by screws. A first wire guide wheel 5 is rotationally installed in the installation cover 28. With the arrangement of the adjusting screw rod 6 and the compression spring 20, a certain tension can be provided for the cable to ensure the normal traction of the cable.

[0026] As Figures 1-2 , Figures 5-6 shown in the figure, a second installation groove 21 is opened on one side of the first installation ring 8. A second installation groove 21 is also opened on one side of the second installation ring 9. A plurality of connecting blocks 22 are fixedly installed in the second installation groove 21. First rotating grooves 23 are opened on both sides of the connecting block 22. A fixing ring 24 is fixedly installed on the other side of the second installation ring 9. The first installation ring 8 and the second installation ring 9 are fixedly connected to each other by screws. The combined body of the first installation ring 8 and the second installation ring 9 is inserted and installed in the corresponding eye hole 14. The fixing ring 24 is inserted into the first installation groove 13 and fixed by screws. Annular second rotating grooves 25 are opened at both ends of the second wire guide wheel 10.

[0027] It should be noted that the present utility model is a lead wire structure of a stranding machine. After the cable passes through the first wire wheels 5 in two wire loading discs 2 in sequence, one end of the cable passes through the corresponding first mounting ring 8 and second mounting ring 9 in the stranding eye disc 3 and extends out. Since the distance between multiple cables is gradually shortened between the first wire wheel 5 and the first mounting ring 8, the cable will exert pressure on the first wire wheel 5 towards the center point of the wire loading disc 2. Thus, the first wire wheel 5 drives the mounting cover 28 to move towards the center point of the wire loading disc 2 in the corresponding U-shaped groove 12. At the same time, the mounting cover 28 drives the adjusting screw 6 to move through the fixing seat 16, and the adjusting screw 6 compresses the compression spring 20 towards the mounting seat 18 through the gasket 19, thereby being able to play a role in buffering the pulling force of the cable. When the compression spring 20 needs to be adjusted or replaced due to reasons such as metal fatigue in the later stage, only the compression degree of the compression spring 20 needs to be adjusted by the nut on the adjusting screw 6 or the compression spring 20 can be quickly replaced;

[0028] In addition, when the conveying direction of the cable changes after passing through the combination of the first mounting ring 8 and the second mounting ring 9, the cable will drive the corresponding second wire wheel 10 to rotate in the second mounting groove 21, and the second wire wheel 10 rotates between two connecting blocks 22 located in the second mounting groove 21 with the help of multiple balls 11 at both ends, thereby reducing the friction force of the cable output. At the same time, the connecting blocks 22 will also fill the gap between the two second wire wheels 10 to prevent damage to the cable skin.

[0029] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model.
