[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Example 1

[0031] Reference Figures 1-6 As shown, this utility model discloses a composite optical cable stranding device for stranding the wires, sheaths, and filler ropes of a composite optical cable. It is installed on the stranding spindle A of a cable production equipment. A wire divider plate B is coaxially sleeved on the stranding spindle. The wire divider plate has multiple wire-passing holes arranged in a circular array around its center, including…

[0032] Cable cage 1, with a central through hole coaxially opened on cable cage 1;

[0033] The first wire splitting mold 2 is coaxially connected to one end of the cable cage 1. The first wire splitting mold 2 has multiple first wire splitting holes 21 arranged in a ring around its center. The end of the first wire splitting mold 2 away from the cable cage 1 is coaxially connected to the main shaft of the stranding body.

[0034] The second wire splitting mold 3 is coaxially connected to the end of the cable cage 1 away from the first wire splitting mold 2. The second wire splitting mold 3 has a plurality of second wire splitting holes 31 coaxially opened on it, which correspond to the positions of the wire, the insulation wire and the filler rope respectively.

[0035] The cable holder 4 has one end coaxially connected to the end of the cable cage 1 where the second splitting mold 3 is installed, and the cable holder 4 has a cable hole 41 coaxially opened on it.

[0036] Specifically, the multiple wires, drop wires, and filler ropes of the composite optical cable first pass through a wire-passing hole, then pass through a first branching hole 21 and a second branching hole 31 in sequence, and finally exit from the cable-gathering hole 41. The diameter of the circle containing the wire-passing hole is larger than the diameter of the circle containing the first branching hole 21, and the coverage area of ​​the first branching hole 21 is larger than the coverage area of ​​the second branching hole 31. Therefore, the wires, drop wires, and filler ropes that move forward and pass through the guide and limit are gradually gathered towards the center. At the same time, during the gathering process, the cable cage 1, the first branching mold 2, and the second branching mold 3 will rotate with the main shaft of the stranding body to twist the wires, drop wires, and filler ropes into a cable core.

[0037] It is conceivable that during the twisting process, the wires, drop wires, and filler ropes undergo three or more rounds of gathering and guiding. During each rounding and guiding process (i.e., passing through the wire hole, the first wire splitting hole 21, and the second wire splitting hole 31 in sequence), the relative positions of the wires, drop wires, and filler ropes are also defined. This ensures the accuracy of the relative positions of each wire during the twisting process, prevents misalignment of each unit during the twisting process, and ultimately ensures that the composite optical cable has better roundness and performance.

[0038] Even better, multiple branch plates can be set on the main shaft of the cable strand, and the diameter of the circle containing the wire passage hole on each branch plate can be gradually reduced, thereby providing better and more uniform guidance and positioning for each wire, which is beneficial to the final structural accuracy of the cable.

[0039] Reference Figure 3 and Figure 4 As shown, the first splitting mold 2 is a circular plate structure. Multiple grooves 22 are spaced apart around its circumference on the circumferential surface of the first splitting mold 2. Multiple limiting protrusions 11, each matching one of the grooves 22, are vertically arranged on the end face of one end of the cable cage 1. The first splitting mold 2 is engaged with the cable cage 1 through the grooves 22 and the limiting protrusions 11. It is conceivable that the cooperation between the limiting protrusions 11 and the grooves 22 can prevent relative rotation between the first splitting mold 2 and the cable cage 1, thereby ensuring the accuracy of the position of each wire.

[0040] Reference Figure 2 As shown, it further includes a transition shaft 5, whose two ends are coaxially connected to the main shaft of the stranding body and the first dividing mold 2 via fasteners. Specifically, the transition shaft 5 includes an intermediate shaft and two connecting plates coaxially connected to both ends of the intermediate shaft. Each connecting plate has multiple first bolt holes arranged in a circular array, which are screwed onto the second bolt holes on the main shaft of the stranding body and the first dividing mold 2, respectively. Installation and disassembly are convenient, and transition shafts of different lengths can be used according to actual needs.

[0041] Reference Figure 6 As shown, the cable tray 41 further includes a tapered section and a straight section. The smaller diameter end of the tapered section connects to the straight section, and the larger diameter end of the tapered section connects to the cable tray 1. Specifically, the tapered section guides the stranded wires, allowing each wire to ultimately enter the straight section and complete the final stranding.

[0042] Reference Figure 5As shown, the second branching hole 31 further includes an electrical wire branching hole 311, a protective cable branching hole 312, and a filler rope branching hole 313. The electrical wire branching hole 311 is a flat hole, the protective cable branching hole 312 is a rectangular hole, and the filler rope branching hole 313 is a round hole.

[0043] Furthermore, there is one wire branching hole 311, which is coaxially opened at the center of the second branching mold 3. There are four filling rope branching holes 313, which are arranged in a rectangular array with the wire branching hole 311 as the center. There are two drop wire branching holes 312, which are symmetrically distributed on both sides of the wire branching hole 311 (specifically, they are located on one side of the two flat positions close to the wire branching hole 311). The two drop wire branching holes 312 are located between two adjacent filling rope branching holes 313.

[0044] Furthermore, a limiting groove 12 is formed on the end face of the cable cage 1 away from the first splitter mold 2. The second splitter mold 3 includes an integrally formed main body 32 and a limiting part 33. The main body 32 is fitted into the central through hole, and the limiting part 33 is fitted into the limiting groove 12. Specifically, the limiting groove 12 is a rectangular groove extending radially along the cable cage 1. The main body 32 has a cylindrical structure and is fitted into the central through hole and fixed by screws screwed into the side of the cable cage 1. After the main body 32 is embedded in the central through hole, the limiting part 33 at one end (the shape and height of the limiting part 33 correspond to the shape and height of the limiting groove 12) is embedded in the limiting groove 12. The cooperation between the limiting part 33 and the limiting groove 12 can prevent relative rotation between the second splitter mold 3 and the cable cage 1, and also facilitates installation by the operator. At the same time, when producing different cables, the second splitter mold 3 can be easily replaced, making the entire device more versatile and economical.

[0045] Furthermore, both the first wire branching hole 21 and the second wire branching hole 31 have chamfers at the ends near the main shaft of the stranding body. The chamfers can guide the wires passing through them and reduce friction between them, thus protecting the wires to a certain extent.

[0046] Furthermore, the side of the cable tray 1 is perforated. The perforated structure facilitates pre-production operations and allows operators to easily monitor the production process. Example 2

[0047] This utility model also discloses a production line, including a composite optical cable stranding device as described in Embodiment 1.

[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
