A two-for-one twisting and plying machine spindle transmission device

Abstract

The invention provides a two-for-one twisting plying machine main shaft transmission device, which relates to the technical field of plying machines, and includes a hollow outer main shaft and an inner mandrel, the inner mandrel is sleeved inside the outer main shaft; a double pulley set is rollingly installed on the outer main shaft, The outer main shaft is fixed with a rotating bearing seat, and the first speed change pulley set and the second speed change pulley set are installed on the rotating bearing seat, and the second speed change pulley set passes through the outer main shaft to connect to the inner mandrel shaft; the double pulley set is connected The first speed change pulley set and reversing gearbox. The inner mandrel shaft of the present invention is arranged inside the outer main shaft, which greatly shortens the axial dimension, simplifies the mechanism, and at the same time makes the overall rigidity of the inner mandrel shaft and the outer main shaft more stable; The first variable speed pulley set and the second variable speed pulley set transmit the reverse power to the inner mandrel, so as to realize the forward and reverse rotation of the small flywheel disc and the large flywheel disc; combined with the new line passing method, multiple times The purpose of the twist length is to double the twisting efficiency.

Description

technical field [0001] The invention relates to the technical field of twisting machines, in particular to a main shaft transmission device of a two-for-one twisting and plying machine. Background technique [0002] Steel wire twisted products are produced by rotating multiple monofilaments through twisting equipment. The twist length control method of the previous steel wire stranding machine is to use the ratio of the driving wheel and the driven wheel of the mechanical reduction box to adjust the gear reduction ratio and change the speed of the traction wheel, so as to control the twist length of the steel wire strand. The mechanical reduction box is used to adapt to the production cycle, because different specifications of steel wire strands have different lay lengths, so every time the machine tool changes a specification of steel wire, it is necessary for the craftsman to match the ratio between the driving wheel and the driven wheel. The gear reduction ratio is not o...

Problems solved by technology

[0004] In the existing tradition, single-twisting machines and double-twisting machines are generally used to produce steel wire twisted products, and their production efficiency is limited to a certain extent. Therefore, a four-fold twisting equipment can be developed. The constant speed forward and reverse rotation of the two flywheels achieves the purpose of multi-twisting steel wire
