Stranding machine stranding tension automatic monitoring system

Abstract

The invention discloses a stranding machine stranding tension automatic monitoring system. The system comprises a human-computer interface, a programmable controller, a tension measuring mechanism, an analog quantity collection device, a wireless communication device, an output control device and a tension adjustment executing device. The human-computer interface transmits set operation state parameters to the programmable controller and displays the process data of the programmable controller in real time. Measuring data of the tension measuring mechanism is collected by the analog quantity collection device and is transmitted to the programmable controller through the wireless communication device. The programmable controller transmits control signals to the output control device through the wireless communication device so as to control the tension adjustment executing device to adjust the tension of stranded wire core. The system has the advantages that the magnitude of the tension on each stranded wire core is measured and controlled in real time in the operation process of a stranding machine, the tension on each stranded wire core is stabilized and balanced and is maintained in a set process requirement range, the requirements of special mechanical performance on cables are met, and the quality level of the products is improved.

Description

technical field [0001] The invention relates to the technical field of cable production equipment, in particular to an automatic monitoring system for strand tension of a stranding machine. Background technique [0002] Most of the stranding machines currently used by cable manufacturers rely on manual adjustment of the tightness of the brake belt of the pay-off reel to adjust the traditional strand production control method of the pay-off tension. During production, it is difficult for the operator to grasp the tension of each twisted wire core on the rotating twisting machine, and it is even more difficult to balance it. As a result, the tension of each stranded wire core of the produced stranded wire is often uneven, and even the problem of wire core breaking occurs during the production process. Cables with uneven core stranding tension have much poorer torsion resistance, and cores with greater stranding tension bear greater mechanical strength during use, so they are ...
