A high-efficiency two-for-one twister

Abstract

The invention provides a high-efficiency two-for-one twisting ply machine, including a ply twister, the ply ply machine includes a fuselage support and a left spindle device and a right spindle device symmetrically installed on the fuselage support; the left spindle device includes a hollow outer spindle and an inner core The shaft and the rotating bearing seat fixed on the outer main shaft, the inner mandrel shaft is rotatably fitted in the outer main shaft; the outer main shaft is rotatably equipped with a central reversing assembly, and the rotating bearing seat is eccentrically equipped with a speed change transmission mechanism, which is respectively connected to the inner mandrel shaft and Center reversing assembly. The inner mandrel shaft of the present invention is set in the outer main shaft, and the overall structure is compact, and at the same time, the overall rigidity of the inner mandrel shaft and the outer main shaft is more stable; the power is realized through the rotating bearing seat, the central reversing assembly, the speed change transmission mechanism, and the reversing gear box Commutation; through the servo motor and encoder, the traction speed can be controlled steplessly, and the purpose of arbitrary lay length control can be achieved. The overall production efficiency is high and the versatility is strong.

Description

technical field [0001] The invention relates to the technical field of twisting machines, in particular to a high-efficiency two-for-one twisting machine. Background technique [0002] Steel wire twisting products are produced by rotating multiple monofilaments through twisting equipment. Generally, single-twisting machines and double-twisting machines are used for production, so the production efficiency of steel wire twisting is limited. [0003] 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...

Problems solved by technology

[0003] 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 gear 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, technicians are required to match the ratio between the driving wheel and the driven wheel. The gear reduction ratio is not only troublesome to replace, but also needs to reserve the ratio of active and driven gears corresponding to various specifications of steel wires, and the production cost is high.

Another important defect is that the gear reducer needs to be maintained regularly, and the oil in the reducer needs to be replaced. If the sealing of the gear reducer is not in place, there will be oil leakage
