[0003] The existing cables have multiple conductors inside, but these conductors are distributed in parallel. Although this can save materials, the connection between the conductors is poor, resulting in poor cable transmission performance. Furthermore, when the conductors in the cable core are connected by twisting, the winding rollers for storage and guidance need to be replaced periodically. Most of the existing winding rollers are fixed with bolts, and bolt removal tools are required for disassembly and assembly, which involves many steps.

[0004] Therefore, this application proposes a multi-core control cable and a concentric stranded cable mechanism. Summary of the Invention

[0011] As a further aspect of the present invention: the upper connecting seat is provided with a connecting mounting bracket and a rotary downward pressing cylinder connected to the mounting bracket.

[0012] As a further aspect of the present invention: a pressure block is provided on the mounting frame, an arc-shaped part is provided on the pressure block, a groove is provided inside the winding roller, and after the ball is inserted into the groove, the arc-shaped part inside the pressure block abuts against the outer wall of the winding roller.

[0016] The advantages of this invention compared to the prior art are: 1. The present invention provides a multi-core control cable and a concentric stranding cable mechanism. When the unwinding drive motor is started, it can drive the square rod to rotate. The winding roller is provided with a drive component. When the square rod is inserted with the drive component, the unwinding drive motor can drive the drive component and the winding roller to rotate, releasing the wire wound on the winding roller.

[0028] Example 3

[0029] like Figure 1 - Figure 7 As shown, an embodiment of the present invention provides a concentric stranding cable mechanism, including a winding roller 1 on which a wire 2 is wound, a winding bracket 3 for mounting the winding roller 1, a rotating disk 4 for mounting the winding bracket 3, a support base 5 rotatably cooperating with the rotating disk 4, and a stranding drive motor 6 mounted on the support base 5 and connected to the rotating disk 4 in a transmission manner.

[0030] The twisting drive motor 6 is used to drive the winding roller 1 on the rotating disk 4 to rotate, twisting the wires 2 released from the winding roller 1 together to form the wire core 11.

[0031] The winding roller 1 cooperates with the winding bracket 3. Multiple winding brackets 3 are provided and are arranged around the center line of the rotating disk 4. When the twisting drive motor 6 is started, the rotating disk 4 can be driven to rotate. The rotating disk 4 can drive the winding bracket 3 and the winding roller 1 on it to rotate.

[0032] In order to assist and restrict the movement of the conductor 2, a guide tube 7 is provided on the winding bracket 3, and a guide hole is provided inside the guide tube 7, through which the conductor 2 passes.

[0033] In order to release the wire 2 wound on the winding roller 1, an unwinding drive motor 8 is provided at the winding bracket 3. A square rod is provided at the output end of the unwinding drive motor 8. A drive component 9 is inserted into the winding roller 1. A square groove is provided in the drive component 9.

[0035] In order to fix the winding roller 1 on the winding bracket 3, several positioning units 10 are provided at the winding bracket 3. When the positioning unit 10 is activated, the winding roller 1 can be pressed onto the winding bracket 3.

[0036] Specifically, the positioning unit 10 includes a ball bearing 1001, a lower connecting seat 1002, and an upper connecting seat 1003. The lower connecting seat 1002 and the upper connecting seat 1003 form an installation cavity. The ball bearing 1001 is inserted into the installation cavity and is in rolling connection with the installation cavity. The lower connecting seat 1002 and the upper connecting seat 1003 are fixedly connected by a pin. The upper connecting seat 1003 is provided with a mounting bracket 1005 and a rotary pressing cylinder 1006 connected to the mounting bracket 1005. The mounting bracket 1005 is provided with a pressure block 1004. The pressure block 1004 is provided with an arc-shaped part. The winding roller 1 is provided with a groove 101. After the ball bearing 1001 is inserted into the groove 101, the arc-shaped part in the pressure block 1004 abuts against the outer wall of the winding roller 1.

[0037] The rotary pressing cylinder 1006 can be of model ACK25-90R / L, which can achieve 90° rotation and pressing functions. When the winding roller 1 is placed on the winding bracket 3, the rotary pressing cylinder 1006 is started, which can drive the mounting bracket 1005 to rotate and press down. The balls 1001 located at the upper and lower ends of the mounting bracket 1005 enter the groove 101, pressing the winding roller 1. When the winding roller 1 rotates, the groove 101 inside it cooperates with the balls 1001 to fix the position of the winding roller 1. Meanwhile, a pressure block 1004 is set on the mounting frame 1005. The pressure block 1004 moves together with the mounting frame 1005 and eventually abuts against the outer wall of the winding roller 1. When the winding roller 1 rotates, the pressure block 1004 can restrict the outer wall of the winding roller 1, further locking the position of the winding roller 1 and preventing the winding roller 1 from falling off the winding bracket 3. Through the cooperation of components such as the rotating pressing cylinder 1006, the winding roller 1 can be quickly locked and released, which facilitates the loading and unloading of the winding roller 1.

[0038] In order to guide the stranded wire core 11, a winding roller 12 with a power function is provided at the support base 5 for winding the wire core 11.

A connecting frame 14 for installation is provided at the auxiliary tube 13. A lifting unit 15 is provided at the connecting frame 14. A support platform 16 is provided at the lifting unit 15. The lifting unit 15 is installed on the support platform 16. The lifting unit 15 can be a cylinder.

[0039] The winding roller 12 rotates, which can wind and wind up the wire core 11 formed by twisting the wire 2, so that the production of the wire core 11 can be carried out continuously.

[0040] The lifting unit 15 can adjust the height of the auxiliary tube 13, while the wire core 11 moves along the auxiliary tube 13 during the movement. The auxiliary tube 13 can assist in positioning and limiting the movement of the wire core 11.

[0041] like Figure 8 As shown, a multi-core control cable includes a frame 17 and wire cores 11. The frame 17 has a storage area, and the wire cores 11 are inserted into the storage area. The frame 17 is wrapped with an outer sheath 18.

[0042] The cable is composed of multiple cores 11, and each core 11 is made up of multiple conductors 2 twisted together. The internal structure of the cable is stable and the power transmission effect is good.

[0043] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will now be explained in conjunction with specific application scenarios: This invention provides a multi-core control cable and a concentric stranding cable mechanism. When the unwinding drive motor 8 is started, it can drive the square rod to rotate. The winding roller 1 is provided with a drive component 9. When the square rod is inserted into the drive component 9, the unwinding drive motor 8 can drive the drive component 9 and the winding roller 1 to rotate, releasing the wire 2 wound on the winding roller 1. The winding roller 1 cooperates with the winding bracket 3. Multiple winding brackets 3 are provided, and the multiple winding brackets 3 are arranged around the center line of the rotating disk 4. When the stranding drive motor 6 is started, it can drive the rotating disk 4 to rotate. The rotating disk 4 can drive the winding brackets 3 and the winding roller 1 on it to rotate. The wire 2 on the winding roller 1 is stranded together to form a wire core 11.

[0044] Place the winding roller 1 on the winding bracket 3, start the rotary pressing cylinder 1006, which can drive the mounting bracket 1005 to rotate and press down. The balls 1001 located at the upper and lower ends of the mounting bracket 1005 enter the groove 101, pressing the winding roller 1. When the winding roller 1 rotates, the groove 101 inside it cooperates with the balls 1001 to fix the position of the winding roller 1. Meanwhile, a pressure block 1004 is set on the mounting frame 1005. The pressure block 1004 moves together with the mounting frame 1005 and eventually abuts against the outer wall of the winding roller 1. When the winding roller 1 rotates, the pressure block 1004 can restrict the outer wall of the winding roller 1, further locking the position of the winding roller 1 and preventing the winding roller 1 from falling off the winding bracket 3. Through the cooperation of components such as the rotating pressing cylinder 1006, the winding roller 1 can be quickly locked and released, which facilitates the loading and unloading of the winding roller 1.

[0045] The cable is composed of multiple cores 11, and each core 11 is made up of multiple conductors 2 twisted together. The internal structure of the cable is stable and the power transmission effect is good.
