Outside-takeup double-twisting machine

Abstract

The invention relates to an outside-takeup double-twisting machine which comprises a takeup bobbin, a traction wheel assembly, a rotating body, a left spindle and a right spindle. The left spindle and the right spindle are arranged on two sides of the rotating body, the takeup bobbin is arranged in the rotating body, thread distributing discs corresponding to the takeup bobbin are arranged on two sides in the rotating body, thread pressing molds are arranged between the thread distributing discs and the rotating body and correspond to the left spindle and the right spindle respectively, thread passing guide wheels are arranged in the left spindle and the right spindle, the left spindle corresponds to the traction wheel assembly, a third rotating spindle is arranged between the left spindle and the traction wheel assembly, and a thread passing guide wheel is also arranged in the third rotating spindle. The outside-takeup double-twisting machine has the advantages that a pair of thread distributing discs and the thread pressing molds are increased in the rotating body, the operability of the double-twisting machine is improved, the halt-production overhaul problem produced by the problems of the left spindle and the right spindle is avoided, constant working of the double-twisting machine is ensured, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of metal wire production, in particular to an outer take-up double-twisting machine. Background technique [0002] Since my country's reform and opening up, the production of metal products has developed rapidly, and the production and demand of metal wire ropes have continued to increase. However, the production technology and production equipment of metal wire ropes have not been greatly improved. What is currently used is the tubular stranding machine of the 1970s, commonly known as the tubular stranding machine. [0003] The rotating body of the tubular stranding machine is a long tube (tube) that can rotate at high speed. Only one pay-off I-shaped wheel is outside the tube, and the rest are inside the tube, so there are many holes on the tube wall for replacement. I-wheel window. A conduit in which the steel wire (or strand) runs along the inner (inner thread) or outer edge (outer thread) of the pipe...

AI Technical Summary

Problems solved by technology

The rotating body of the tubular stranding machine has many disadvantages: first, the moment of inertia is large, which limits the increase of the speed; second, the length-to-diameter ratio is large, and it is difficult to achieve a good dynamic balance; Intensity, and the "diabolo" effect makes the noise louder; the fourth is to limit the capacity and number of I-shaped wheels
