Problems solved by technology

Roughly controlling the tension leads to a large tension error between the previous cycle and the subsequent cycle during the weaving process of the loom, which is manifested in the uneven gap between the weft yarns on the cloth surface. If it is light, the grade of the cloth will be reduced, and if it is serious, the fabric will become a waste product.

Embodiment Construction

[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0014] According to the tension control method of the present invention, according to the specific value of warp yarn tension accurately collected in the movement interference of heald frame, beating-up, warp stopper vibration and loom vibration during the operation of the loom, the collected value is passed through a data processing algorithm Calculate the real warp tension value, control the speed and position of the let-off motor according to the change of the real warp tension, and precisely control the warp tension through the tension control device to keep it constant.

Abstract

The invention discloses a tension control method. Specific number values of warp tension are accurately acquired according to a heald frame, beating-up, dropper shake and weaving machine vibration in the running process of a weaving machine, calculated by means of a data processing algorithm to obtain a real warp tension value, a detection value in the running process of the weaving machine is not influenced by measurement errors caused by rear beam movement and heald frame opening and closing through a tension control device, constant tension is achieved, and even and consistent upper weft threads of a fabric are kept.

Description

technical field [0001] The invention relates to the technical field of textile technology and equipment, in particular to a method and device for controlling the tension of a loom. Background technique [0002] The loom using electronic warp let-off in the textile production process needs to detect the tension of the warp yarn. It is ideal to keep the tension constant during the weaving process. In the actual production process, due to the many changes in the weaving process and fabric, the diameter of the warp beam supplying the warp yarn varies with the The supply of warp yarns is gradually decreasing, and warp yarn deformation cannot be predicted, so tension control is a technical difficulty. Generally, rough control is used to allow a large fluctuation range. Roughly controlling the tension leads to a large tension error between the previous cycle and the subsequent cycle during the weaving process of the loom, which is manifested in the uneven gap between the weft yarns...
