Problems solved by technology

Because the stranding device, wire reel frame and stranding eye mold of the above structure are located at the same horizontal position, and the stranding device, wire wheel frame and stranding eye mold are all on the same axis, the length of the equipment in the horizontal direction is longer. And the stranding method is single, the wire is prone to jumping when entering the stranding eye mold, and the quality of the stranding is not high

Embodiment 1

[0052] The untwisting and twisting machine described in this embodiment, such as Figure 1 to Figure 3 As shown, it includes an organic table 1, a wire feeding device 2, a wire twisting device 3, a wire winding device 4, and a transmission device 5. The machine table 1 is provided with a first working plate 11 and a second working plate 12, the first The working plate 11 and the second working plate 12 separate the machine into three working chambers, namely the first working chamber 13, the second working chamber 14 and the third working chamber 15, respectively. The second working chamber The two sides of 14 are provided with through holes 141; the present invention divides the working chamber formed by the inner cavity of the machine 1 into three, which is convenient for installing various devices inside, has a simple structure and is not easy to cause confusion. The wire feeding device 2 includes at least one set of built-in wire feeding devices 21, the built-in wire feedin...

Embodiment 2

[0056] The untwisting and twisting machine described in this embodiment, such as Figure 1 to Figure 3 As shown, the difference between this embodiment and the first embodiment is that the wire feeding bracket 212 includes a bracket portion 212a and a hollow shaft 212b, the wire feeding wheel 211 is clamped on the bracket portion 212a, and the hollow shaft 212b passes through Located at the lower end of the bracket portion 212a, the synchronous gear I213 is sleeved on the hollow shaft 212b. The wire feeding bracket 212 in this embodiment is composed of a bracket portion 212a and a hollow shaft 212b. The wire entering through the wire feeding wheel 211 can be conveyed downward along the hollow shaft 212b, and the wire feeding is stable and reliable.

[0057] Furthermore, the stranding device 3 further includes a lead wheel 34 which is arranged under the hollow shaft 212 b through a fixed bracket 35, and the fixed bracket 35 is fixedly installed on the machine table 1. By arrangin...

Embodiment 3

[0060] The untwisting and twisting machine described in this embodiment, such as Figure 1 to Figure 3 As shown, the difference between this embodiment and the first embodiment is that the winding device 4 further includes two linkage rods 44, and the two linkage rods 44 are respectively connected to a synchronous transmission rod 51 via a linkage gear 45. It is connected to the support rod 52 respectively, and the linkage gear 45 is arranged on the winding frame 41. In this embodiment, when the synchronous transmission rod 51 rotates, the linkage gear 45 can drive the linkage rod 44 to rotate at the same speed, thereby driving the winding frame 41 to rotate at the same speed.

[0061] Furthermore, the wire winding device 4 further includes a wire outlet wheel 46, which is fixed to the wire winding frame 41 and located below the stranding eye mold 32. In this embodiment, after the wire is stranded in the stranding die 32, the winding material can be conveyed along the wire exit ...

Abstract

The invention relates to the technical field of stranders, in particular to a back twist strander capable of eliminating torsion stress. The back twist strander comprises a stand, a feeding device, a stranding device, a transmission device and a coiling device, wherein the stand is provided with a first working plate and a second working plate which divide the stand into three working chambers. The back twist strander provided by the invention achieves the aim of eliminating torsion stress generated in the total stranding process of wires through controlling the rotating speed of a feeding end to be consistent with the rotating speed at a coiling end by using the same transmission device. The transmission device of the back twist strander transmits power through a synchronous transmission rod as well as a synchronous gear and a synchronous belt which are in the same specification. The back twist strander is simple and compact in structure, capable of totally stranding a plurality of wires, varied in stranding way and high in stranding quality, and no jumping phenomenon is caused in the total stranding process of the wires.

Description

Technical field [0001] The invention relates to the technical field of stranding machines, in particular to an untwisting stranding machine capable of eliminating torsional stress. Background technique [0002] Stranding machine is a widely used equipment in the wire and cable industry. It can be widely used in various types of soft / hard conductor wires (copper wire, enameled wire, tinned wire, copper clad steel, copper clad aluminum, etc.) and electronic wires. Twisted. In the process of stranding the above-mentioned wire, because the speed of the wire feeding device and the winding device are not synchronized, the wire is inevitably twisted during the stranding process, resulting in a torsional stress. The torsional stress will exist in the stranded wire. It is wound on the outlet reel, which will seriously affect the quality of the stranded wire and the effect of the outlet reel. Especially when the outlet reel is full and the stranded wire outside the outlet reel needs to b...
