Warp tension collection device

Abstract

The invention relates to a warp tension acquisition device, which comprises a support assembly, a tension sensor, a sensor bracket, a warp sheet bearing assembly and a presser bar; the tension sensor is connected with the support assembly through the sensor bracket; the warp sheet bearing assembly is arranged on the tension sensor; the presser bar is located at the upper part of the warp sheet bearing assembly, and is connected with the support assembly; the tension sensor is electrically connected with an electric cabinet control circuit of a weaving machine; the electric cabinet control circuit is used for controlling a let-off servo of the weaving machine according to a signal acquired by the tension sensor, and then, the rotating speed of a let-off servo motor of the weaving machine is controlled by the let-off servo. According to the warp tension acquisition device, the tension of a warp sheet can be converted into an electric signal through the tension sensor, and after the electric signal is received by the control circuit, the rotating speed of the let-off servo is controlled according to the set requirement or the production requirement; meanwhile, through the regulation of the rotating speed of the let-off servo motor, the tension of the warp sheet can also be constant within a certain range value, and the closed-loop accurate control of the weaving machine is realized.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a warp tension collection device mainly applied to glass fiber looms. Background technique [0002] The existing fiberglass looms only control the tension of the warp yarns alone, but do not control the tension of the warp yarns through the warp let-off motor. Moreover, the structure is complex, and the quality of the produced products is poor. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a warp tension collecting device with simple and reasonable structure, small volume and convenient installation. [0004] The object of the present invention is achieved in this way: [0005] A warp tension acquisition device, characterized in that it includes a support assembly, a tension sensor, a sensor holder, a yarn support assembly, and a yarn pressing rod, the tension senso...
