Problems solved by technology

[0003] In the existing stranding machine, the radius of the take-up wheel is measured according to the tracking, so as to calculate the real-time required take-up tension. The change of traction tension cannot keep up with the take-up speed, so the lay length of the stranded wire will inevitably change, and the stranded wire is easy to bend and twist, which affects the use

Abstract

Disclosed is a stranding machine with a frequency division lay control function. The stranding machine comprises a driving winch variable-frequency controller, a traction wheel motor and a winch driving motor; and the length of a real-time stranded wire is calculated through the rotating speed of the main motor and the rotating speed of the winch, the pulse quantity of the traction wheel is changed, and the electronic gear ratio of the driver is controlled to control the speed ratio of the traction wheel motor to the winch driving motor, so that the speed ratio of the traction wheel and the winch is changed so as to achieve the purpose of controlling the lay.

Description

technical field [0001] The invention relates to the technical field of stranding machines, in particular to a stranding machine for frequency division control of strand length. Background technique [0002] Stranding machine is a kind of cable equipment used for twisting core wires such as power cords, earphone cords, and electronic wires. During the twisting process, it is necessary to change the twisting distance by changing the tension of the take-up pulley, but during the take-up process , the radius of the take-up pulley is constantly increasing, and the required traction tension also needs to be changed. [0003] In the existing stranding machine, the radius of the take-up wheel is measured according to the tracking, so as to calculate the real-time required take-up tension. The change of traction tension cannot keep up with the take-up speed, so the lay length of the twisted wire will inevitably change, and the twisted wire is easy to bend and twist, which affects th...
