Description

Technical Field

[0001] The invention relates to the technical field of electric power equipment, in particular to a cable stranding machine with adjustable strands. Background Art

[0002] Cable stranding machine is a kind of wire and cable processing equipment, which can be widely used in the stranding of various soft / hard conductor wires (such as cables, enameled wires, tinned wires, copper-clad steel, copper-clad aluminum, etc.) and electronic wires (such as power cords, headphone wires, telephone wires, PVC wires, network wires, etc.), and twisting multiple wires or conductor wires together according to a certain rule to form wire and cable products with certain strength and structure. Cable stranding machines can generally be divided into many types according to the stranding method, such as single stranding machines, pair stranding machines, high-speed stranding machines, back-twisting machines, cage stranding machines, frame stranding machines, tubular stranding machines and disc stranding machines. When the cable passes through the twisting bow on the stranding machine, the twisting bow uses a circular motion to make each single cable spirally wound together. After copper wires of different specifications and numbers are twisted together in a certain arrangement order and twist pitch, they become conductors with larger diameters. This kind of twisted conductor is much softer than a single cable of the same diameter, and the bending performance of the wires made is also better.

[0003] In the existing cable twisting machines, the substrate feeding rollers are mostly fixed during twisting. When the torsion between the cables is too large, the cables are prone to breakage. In addition, it is difficult to control the travel speed of the cables during twisting. After twisting, they need to be wrapped separately, which is costly and wastes manpower and material resources. Therefore, a cable twisting machine with adjustable twisting wires is proposed. Summary of the invention

When the driving shaft 8 rotates, it drives the third connecting shaft 27 to start rotating, so that the dividing rod 28 and the wire release hole 29 rotate accordingly. When the second connecting rod rotates, it drives the clamping jaw 25 to start rotating, so that the discharge roller inside the clamping jaw 25 rotates around the third connecting shaft 27 and rotates at the same time. At this time, the head end cables of the discharge rollers on both sides pass through the wire release holes 29 at the corresponding positions and enter the twisting reversing grooves 32 between the twisting wheels 31. They are twisted into one strand under the rotation of the dividing rod 28 and the self-rotation of the discharge rollers. The self-rotation of the discharge rollers can prevent the cables from breaking when the torque is too large, thereby improving the twisting effect.

[0033] When the driving shaft 8 rotates, it drives the first driving wheel 34 to start rotating. When the first driving wheel 34 rotates, it drives the first driven wheel 35 meshed with it through the first transmission chain 36 to start rotating, so that the fourth connecting shaft starts to rotate. When the fourth connecting shaft rotates, it drives the second driving wheel 38 to start rotating. The twisted cable passes through the axis of the rotating ring 49 along the feed hole 48. When the second driving wheel 38 rotates, it drives the second driven wheel 51 meshed with it through the second transmission chain 39 to start rotating, so that the fifth connecting shaft 50 starts to rotate. When the fifth connecting shaft 50 rotates, it drives the driving gear 54 to start rotating, so that the rotating ring 49 starts to rotate around the cable. When the rotating ring 49 rotates, it drives the unwinding rack and the coating roller 53 to start rotating around the cable. At this time, the head end of the coating film is wrapped around the surface of the cable. With the continuous rotation of the coating roller 53, the cable at the axis of the rotating ring 49 can be continuously and automatically coated, thereby realizing the synchronous coating of the twisted cable, so that the coating rate matches the twisting rate to avoid the phenomenon of leaking.

[0034] When the fifth connecting shaft 50 rotates, it drives the driving bevel gear 40 to start rotating. When the driving bevel gear 40 rotates, it drives the driven bevel gear 41 meshing with it to start rotating, so that the third driving wheel starts to rotate. When the third driving wheel rotates, it drives the third driven wheel 45 meshing with it through the third transmission chain 42 to start rotating, so that the take-up shaft 44 starts to rotate. The head end of the cable is coated and passes through the limit ring to be connected to the outer wall of the take-up roller 46. When the take-up roller 46 rotates, it can drive the cable to rotate accordingly, thereby realizing automatic winding of the cable. At the same time, the winding rate is matched with the twisting rate to avoid winding too fast and causing the cable to be pulled apart or winding too slowly and causing the cable to bend and affect the twisting effect.

[0035] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
