Roller assembly for transmitting after stranding of multiple copper stranded wires

Abstract

The invention discloses a roller assembly for transmitting after stranding of multiple copper stranded wires. The roller assembly comprises a workbench and two rows of side-pressing rollers, wherein a press-down roller is arranged on a supporting plate in a rotating way. Each side-pressing roller comprises an upper end cover, a side-pressing sleeve and a lower end cover, a stand column is arranged at the middle part of the lower end cover, the upper end part of the stand column penetrates through the upper end cover, the side-pressing sleeve of which the middle part is sunk inwards sleeves the stand column, a horizontal through hole is formed at the middle parts of the upper end face of the side-pressing sleeve and the upper end cover along the radial direction of the stand column, an adjusting hole is formed at the upper section of the stand column, a T-shaped block is mounted in the horizontal through holes, two sides of the horizontal section of the T-shaped block are respectively connected with the inner wall of the side-pressing sleeve, and the vertical section of the T-shaped block extends up inside the adjusting hole. After the side-pressing sleeves move up, spacing between contact points of two adjacent side-pressing sleeves and copper stranded wires is reduced, extrusion force generated by the outer walls of the side-pressing sleeves is increased and then the copper stranded wires have local bending; meanwhile, the pulled copper stranded wires regain tension through the local bending, thus avoiding the problem that the parts of the copper stranded wires, entering a winding drum, are too loose.

Description

technical field [0001] The invention relates to the field of copper stranded wire processing, in particular to a roller assembly for conveying multi-strand copper wire after twisting. Background technique [0002] The stranding machine is a kind of stranding mechanical equipment that can be widely used in various types of soft / hard conductor wires, so that multiple single conductors are twisted into one strand to meet the technical requirements of the wire. According to the twisting method, the stranding machine can generally be divided into single stranding machine, pair stranding machine, high-speed stranding machine, untwisting machine, cage stranding machine, frame stranding machine, tubular stranding machine and disc stranding machine machine etc. [0003] After the copper wire is twisted in the stranding machine, it is wound up into a reel through its outlet for easy transportation and storage. However, when the copper stranded wire is rewound, a motor drives the ree...

AI Technical Summary

Problems solved by technology

However, when the copper stranded wire is rewound, a motor drives the reel to rotate, and the copper stranded wire is drawn to the reel from the outlet of the stranding machine, because the reel body rotates continuously with the motor, and the copper stranded wire is pulled There will be a certain degree of radial runout, that is, local stress concentration on the copper strands; and once the reel motor stops, the tension of the drawn copper strands will directly decrease, that is, the copper strands will be slack, Causes uneven distribution of copper strands on the reel
