Therefore, they are widely used in the construction of communication lines.

[0003] In the production process of communication cables, single twisting machines are one of the important cable twisting equipment. Single twisting machines can generally be divided into three types: vertical single twisting machines, cantilever single twisting machines and suspension frame single twisting machines.

Then reset the mounting base and use the limit bolts to fix it to the fixing hole on the base plate. If you want to reduce the number of twisted original wires, just reduce the original wire winding roller in the mounting ring seat. When processing the communication stranded wire, the servo motor The output shaft of one drives the reducer one to rotate, and the reducer one drives the rotating shaft to rotate synchronously while rotating.

At the same time, the servo motor two drives the cantilever to rotate through the reducer two, thereby rotating the collection line passing through the traction wheel two to form a lay pitch, and at the same time, the servo motor three drives the take-up roller in the cantilever to rotate, so that the twisted wire of the communication cable is arranged left and right on the take-up roller and wound on the take-up roller.

[0017] The present invention provides a fully automatic cantilever single twisting machine for communication cables, which has the following beneficial effects:

[0018] 1. The present invention uses an adjustable original wire winding roller. The number of original wire winding rollers on the rotating shaft can be adjusted and set according to the needs of the user or the specifications of the communication cable. In addition, by using a method of leading multiple wires on one shaft, the output balance of the original wires on the original wire winding rollers of the communication cable is ensured, the tension balance of the communication cable strands is increased, and the processing and use of the communication cable are facilitated.

[0019] 2. The present invention sets a front traction mechanism, a middle traction mechanism and a rear traction mechanism, so that the original wire output by the original wire winding roller passes through the front traction mechanism, the middle traction mechanism and the rear traction mechanism in turn to pull the twisted wire on the same horizontal line, thereby reducing the bending of the original wire cable during the twisting process and improving the quality of the finished communication cable.

[0020] 3. The present invention sets the lay length through the control panel and controls it through the display screen and function buttons on the control panel. At the same time, the computer automatically tracks and corrects the pitch, so the pitch error is small and can be adjusted at any time, which is convenient for the processing and control of communication cables.
