Technical Field

The invention relates to a vertical high-speed twisting stranding machine, and belongs to the technical field of textile machinery.

Background

The cable is woven from a plurality of strands, each of which is made by a twist stranding machine. Most of the existing stranding machines are single-twisting stranding machines, the single-twisting stranding machines adopt an integral frame to rotate, the speed is low, the efficiency is low, after the accurate calculation of a technician is needed for the adjustment of the pitch of the wire arrangement, the stranding and twisting can be achieved only by replacing a matching gear, and the requirement on operators is high.

There is also a two-for-one twister on the market, but there are the following drawbacks:

1. narrow space and inconvenient operation: the existing two-for-one twister is provided with a twisting change gear which is arranged in a cover, and workers need to bend down to enter the cover;

2. the bobbin needs to be threaded, and the bobbin is inconvenient to take;

3. the twisting step is too much, the screw is loosened and rotated to pass through the direction of the wire wheel to be another twisting direction, and then the reversing seat is locked; then the winding direction of the grooved pulley is changed; then the screw is disassembled to mount the reversing fixed plate to the other fixed seat for locking; the position of the idler wheel in the change gear is adjusted again; finally, the motor is switched on the control panel to rotate positively and negatively, and the five steps are inexhaustible and complicated.
