[0002] In the early stages of wire and cable production, cabling was mainly done manually or semi-mechanized, which was inefficient and difficult to ensure quality. With the acceleration of industrialization, simple mechanical cabling machines began to appear, which twisted multiple single wires or insulated wires together through a rotating twisting disk to form cables with certain strength and electrical properties.

[0003] In the cable manufacturing process, cabling is a crucial link. Early cabling machines were mostly single-layer twisted designs, that is, all cables were twisted on the same plane. However, with the complexity of cable structures and the improvement of performance requirements, single-layer twisting can no longer meet all needs. Although there are horizontal cabling machines that can complete the production of double-layer twisted umbilical cables, the overall production line of the horizontal cabling machine is very long, resulting in a large footprint. In addition, the horizontal structure of the cabling machine has more capstans, and the operation of the upper reel is more complicated. At the same time, there is a lack of corresponding tension adjustment. When the winding tension is insufficient, the winding may not be firm, and excessive tension may damage the cable or cause the cable to be thinned or even broken.

The second wire drum rack 20 is connected to the second support plate 4 through a second lifting block 21 with limited sliding. The second lifting block 21 is threadedly connected to the second screw rod 22. The second screw rod 22 is rotatably installed inside the second support plate 4. The second worm gear 23 is fixedly connected to the second screw rod 22, and the second worm gear 23 is meshingly connected to the second worm 24. The second worm gear 24 is rotatably installed inside the second support plate 4.

[0039] Furthermore, the inner layer tension adjustment mechanism also includes a second motor 27 for driving the second worm gear 24 to rotate, one end of the second worm gear 24 is fixedly connected to the third bevel gear 25, the third bevel gear 25 is meshingly connected to the fourth bevel gear 26, the fourth bevel gear 26 is fixedly connected to the output shaft of the second motor 27, the second motor 27 is fixedly installed inside the support column 28, and the rotation of adjacent third bevel gears 25 does not interfere with each other.

[0040] Furthermore, the inner layer wrapping mechanism includes a first wrapping disk 46 for wrapping connection, the first wrapping disk 46 is provided with a first wrapping belt 47 for winding, the first wrapping disk 46 is rotatably mounted on the first gear 43, the first gear 43 is rotatably mounted on the third support frame 41, the third support frame 41 is fixedly mounted on the first support frame 5, the first support frame 5 is provided with a second threading hole 40 for passing the outer cable 17 and the inner cable 18, the first gear 43 is meshingly connected with the second gear 44, the second gear 44 is fixedly connected to the output shaft of the fourth motor 45, the fourth motor 45 is fixedly mounted on the third support frame 41, and the third support frame 41 is provided with a avoidance groove 42 for avoiding and guiding the outer cable 17.

[0041] Preferably, one end of the inner cable 18 is wound and released to be connected to the second winding roller 19, and the other end of the inner cable 18 is driven by the traction machine 7, and the inner cable 18 passes through the first threading hole 30 on the limit plate 29 and the second threading hole 40 on the first support frame 5 in sequence to form a twist. When the tension twisting strength of the inner cable 18 is adjusted according to the traction needs of the traction machine 7, the output shaft of the second motor 27 drives the fourth bevel gear 26 to rotate, and drives the second worm 24 to rotate under the meshing connection between the fourth bevel gear 26 and the third bevel gear 25, and drives the second lead screw 22 to rotate under the meshing connection between the second worm 24 and the second worm gear 23, so that the second wire drum frame 20 can drive the second winding roller 19 to move up and down under the threaded connection between the second lifting block 21 and the second lead screw 22 and the limiting guiding action of the second lifting block 21 itself, so as to realize the tension adjustment of the inner cable 18 to a certain extent, so as to facilitate the subsequent wrapping processing operation.

At this time, the limit block 31 moves in the direction close to the connecting cover 33 under the reset action of the spring 36, and the tension adjustment is simpler, which further improves the stability of the inner layer twisting of the inner cable 18. The second rotating base 3 can correspondingly drive the inner cable 18 at the second winding roller 19 on the second support plate 4 to rotate and twist around the support column 28 as the center.

[0043] When the inner cable 18 passes through the third support frame 41 for twisting, the output shaft of the fourth motor 45 drives the second gear 44 to rotate, and drives the first wrapping disk 46 to rotate about the center of the twisting of the inner cable 18 under the relationship of the second gear 44 and the first gear 43 being meshed and connected. At this time, the first wrapping belt 47 on the first wrapping disk 46 can be rotatably wrapped around the twisted inner cable 18 to complete the wrapping operation of the inner layer inner cable 18.

[0044] Example 2 like Figure 1 to Figure 17 As shown, on the basis of Example 1, this embodiment further includes an outer layer tension adjustment mechanism, which is installed at the connection between the first support plate 1 and the first support frame 5, and is used to adjust the tension of the traction twisting of the external cable 17.

When the tension twisting strength of the outer cable 17 is adjusted according to the traction needs of the traction machine 7, the output shaft of the first motor 8 drives the first bevel gear 9 to rotate, and drives the first worm 11 to rotate under the relationship of the first bevel gear 9 and the second bevel gear 10 being meshed and connected, and the first worm 11 is meshed and connected with the first worm wheel 12. , drives the first screw rod 13 to rotate under the relationship, so that under the threaded connection between the first lifting block 14 and the first screw rod 13 and the limiting guiding action of the first lifting block 14 itself, the first wire drum frame 15 can drive the first winding roller 16 to move up and down, thereby realizing the tension adjustment of the external cable 17, which is convenient for the subsequent wrapping processing operation. The first rotating base 2 can correspondingly drive the external cable 17 at the first winding roller 16 on the first support plate 1 to rotate and twist around the support column 28 as the center, and the rotation of the first rotating base 2 and the second rotating base 3 is relatively independently set, that is, the outer layer and the inner layer can be twisted in the same way or can be twisted and rotated in the opposite direction.

At this time, the second wrapping tape 50 on the second winding disk 49 can be rotatably wrapped around the twisted outer cable 17 and the inner cable 18, thereby completing the double-layer wrapping processing of the outer cable 17 and the inner cable 18 accordingly.

[0049] Through this tension adjustment, the tension of each cable in the twisting process can be made more uniform, avoiding problems such as twisting, deformation or breakage of the cable due to uneven tension, thereby improving the overall quality and reliability of the cable. At the same time, moderate tension can make the wires inside the cable fit tightly, reducing wear and fatigue caused by looseness or excessive gaps, thereby helping to extend the service life of the cable and reduce the frequency of replacement and maintenance.

[0050] This device adopts a multi-reel design and can process multiple cables at the same time, which greatly improves the parallel processing capability of the twisting process, significantly improves production efficiency, increases production flexibility and diversity, and meets the production needs of cables of different specifications and types. The vertical design enables the cables to better maintain a vertical state during the twisting process, reduces the problem of uneven tension caused by gravity, improves the uniformity and consistency of twisting quality, and effectively utilizes vertical space.
