Description

Technical Field

[0001] The invention belongs to the technical field of cables, and in particular relates to a cable stranding structure and method for cable production. Background Art

[0002] In today's era of high integration of digitalization and electrification, power supply is the cornerstone of social operation and the lifeblood of information transmission, and cables play an irreplaceable role.

[0003] Different fields have put forward strict and diverse requirements on cable performance. In the field of power transmission, in order to meet the needs of long-distance and large-capacity power transmission, ultra-high voltage cables must not only have excellent conductivity to reduce transmission losses, but also have strong mechanical strength to resist tension and torque during laying and thermal stress during long-term operation; in the field of communications, high-speed and large-capacity data transmission has prompted cables to develop in the direction of high frequency and low loss, requiring the internal structure of the cables to be highly regular to reduce signal interference and attenuation; and in special application scenarios such as aerospace and deep-sea exploration, cables need to adapt to extreme temperatures, pressures, and corrosive environments, and require extremely high levels of refinement in their materials, structures, and processes.

[0004] However, in the process of producing and twisting existing wire harnesses, they are often divided into main wires and auxiliary wires, and the auxiliary wires are often twisted on the main wires. However, the main wires are often long enough, but the auxiliary wires are easily not long enough. Therefore, in the process of twisting, when the auxiliary wires are separated from the unwinding roller, on the one hand, confusion is easy to occur, and on the other hand, when connecting them with the newly placed auxiliary wires, it is easy to find the joints, which causes more trouble.

[0044] Embodiment 2:

[0045] The difference between the above embodiment and this embodiment is that: Figures 1 to 3 and Figure 5 As shown, a cable stranding structure for cable production, the driving assembly includes a servo motor 201, the servo motor 201 is arranged on the mounting base 101, the output end of the servo motor 201 is fixedly connected with a rotating rod 2011, the end of the rotating rod 2011 away from the servo motor 201 is provided with a driving gear 2012, the driving gear 2012 is meshed with a gear ring 2013, and the gear ring 2013 is arranged on the first annular mounting plate 1021.

[0047] like Figures 1 to 6 and Figure 7 As shown, further, a placement plate 3023 is provided on the opposite side wall of the two L-shaped plates 3014, and a moving plate 302 is provided on the opposite ends of the two placement plates 3023.

[0048] like Figures 1 to 6 and Figure 7 As shown, further, two mutually symmetrical guide assemblies 107 are provided on the mounting base 101, and a main line body 106 is provided between the two guide assemblies 107, and the main line body 106 also passes through the first annular mounting plate 1021 and the second annular mounting plate 1023. In this configuration, the placement position of the main line body 106 is determined.

[0049] Embodiment 3:

[0050] The present invention also discloses a cable stranding method for cable production, the steps of which are as follows:

[0051] Step 1: First, the staff connects the main line body 106 and the wire harness body 1043 set on the placed wire harness roller 1041. When the connection is completed, the existing transmission equipment and the transmission unit 200 are started so that the wire harness body 1043 can be twisted on the main line body 106;

[0052] Step 2: When the wire harness body 1043 is missing during reuse, that is, when it just falls off from the wire harness roller 1041, the clamping plate 3015 in the clamping and disassembling unit 300 squeezes and clamps the wire harness body 1043 that is about to fall off on the main wire body 106;

[0053] Step three: When the clamping and disassembling unit 300 moves, it can also drive the annular positioning plate 105 to move, so that the annular positioning plate 105 can be away from the first fixed unwinding assembly 104 and the second fixed unwinding assembly 1045, thereby facilitating the disassembly and replacement of the placed wire harness roller 1041.

[0054] The implementation principle of a cable stranding structure and method for cable production in this embodiment is as follows:

[0055] First, the staff connects the main line body 106 with the wire harness body 1043 set on the placed wire harness roller 1041. When the connection is completed, the existing transmission equipment and the transmission unit 200 are started to operate;

[0056] When the transmission unit 200 is running, the servo motor 201 is running. When the servo motor 201 is running, it can drive the rotating rod 2011 to rotate. When the rotating rod 2011 rotates, it can drive the driving gear 2012 to rotate. When the driving gear 2012 rotates, it can drive the gear ring 2013 to rotate. Because the gear ring 2013 is set on the first annular mounting plate 1021, and the first annular mounting plate 1021 is rotatably set on the first mounting seat 102, it can ensure that the gear ring 2013 will not fall off, and at the same time, it can drive the first annular mounting plate 1021 to rotate.

[0057] When the first annular mounting plate 1021 rotates, it can drive the sliding rod 103 to rotate, and at the same time, it can also drive the positioning rod 1042 to rotate, because the positioning rod 1042 is connected to the telescopic rod 1053, and the telescopic rod 1053 is connected to the circular mounting plate 1052, and the circular mounting plate 1052 is connected to the annular positioning plate 105 through the fixed rod 1051, so that the annular positioning plate 105 is rotated, and when the annular positioning plate 105 rotates, it can also drive the first fixed unwinding assembly 104 and the second fixed unwinding assembly 1045 to rotate, so that the inner cavity structure of the first annular mounting plate 1021 also rotates together;

[0058] At the same time, when the telescopic rod 1053 rotates, the second annular mounting plate 1023 can also be driven to rotate through the connecting block 3024, because the inner cavity of the second annular mounting plate 1023 is provided with a mounting frame 301, so that the mounting frame 301 can rotate, and when the mounting frame 301 rotates, it can drive the bearing 3011, the rotating rod 3012, the torsion spring 3013 and the L-shaped plate 3014 to rotate, and when the L-shaped plate 3014 rotates, it can drive the placement plate 3023 to rotate, thereby driving the movable plate 302 to rotate, so that the inner cavity structure of the second annular mounting plate 1023 also rotates together;

[0059] When the harness body 1043 on the harness roller 1041 is completely unwound or squeezed, the transmission component slows down until the harness body 1043 is detached from the harness roller 1041, at which time the entire device stops running. However, at this time, the L-shaped plate 3014 can quickly drive the clamping plate 3015 to clamp the harness body 1043 to the main line body 106 with the assistance of the torsion spring 3013 and the rotating rod 3012 (because the harness body 1043 falls off, the harness body 1043 and the main line body 106 are in a taut state when they are not detached, so the clamping plate 3015 can no longer drive the taut harness body 1043 under the torsion of the torsion spring 3013, so the torsion spring 3013 will not act on the L-shaped plate 3014 to rotate), and the harness body 1043 is clamped and positioned, so that when the harness body 1043 is replaced, it is easy to find the harness head for connection;

[0060] When the L-shaped plate 3014 rotates, it can drive the placement plate 3023 to rotate, and when the placement plate 3023 moves, it can push the movable plate 302 to drive the annular positioning plate 105 to move horizontally (because a moving slide groove 3021 and a moving slider 3022 are provided between the placement plate 3023 and the movable plate 302, thereby ensuring that a moving force can be given to the movable plate 302, and the movable plate 302 is connected to the annular positioning plate 105, wherein the annular positioning plate 105 is connected via a connecting rod 1032 and a second sliding block 1034, and the second sliding block 1034 moves on the sliding rod 103, thereby ensuring that the annular positioning plate 105 can move);

[0061] When the annular positioning plate 105 moves, the circular mounting plate 1052 can be driven to move through the fixed rod 1051, so that the telescopic rod 1053 is contracted, thereby ensuring that the annular positioning plate 105 can leave the first fixed unwinding assembly 104 and the second fixed unwinding assembly 1045, so that it is convenient for the staff to take out the wire harness roller 1041 for replacement.
