Problems solved by technology

When the mechanic adjusts the yarn guide distance, he can only set a yarn guide distance according to the weft insertion needs at that time. As the diameter of the package becomes smaller and smaller, the optimal yarn guide distance will become shorter and shorter. If the yarn distance remains the same, the tension fluctuation will be too large due to too many nodes, especially when the package yarn is poorly formed, it is more likely to cause the machine to stop and even cause weaving defects that seriously affect the quality of the fabric surface

Embodiment Construction

[0021] Now in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0022] The method for automatically adjusting the yarn guide distance of the present invention is realized in this way. The bobbin support device 6 is connected to the spring 17, and the spring is compressed by the bobbin's own weight. When the bobbin is full, the spring is compressed to the maximum extent. Long, when the bobbin is decomposed into a small bobbin, the spring is as straight as possible. To achieve the purpose of long yarn guiding distance for large bobbins and short yarn guiding distance for small bobbins. The bobbin supporting device 6 is composed of three rings, the combination of the first ring 13 and the second ring 14 can satisfy the placement of tapered bobbins, and the combination of the second ring 14 and the third ring 16 can satisfy the placement of parallel bobbins.

Abstract

The invention discloses a method for adjusting thread guide distance automatically. It makes a combined support ring body connect with a spring. The self-weight of bobbin is used to compress the spring to achieve long thread guide distance of big bobbin and short thread guide distance of small bobbin. The combined ring body comprises three ring bodies. The combination of the first ring body and the second ring body is used to satisfy the placement of taper bobbin and the combination of the second ring body and the third ring body is used to satisfy the placement of parallel bobbin. Compared with prior technology, merits of the invention is that by adjusting the distance of unwinding thread guide automatically, the diameter of bobbin yarn is corresponding to the optimal thread guide distance; the tension wave of yarn is decreased; the number of weft stop is decreased and the production quality is improved.

Description

technical field [0001] The invention belongs to the field of textiles, and relates to a method and a device for automatically adjusting the weft guide distance of a loom. Background technique [0002] With the development of science and technology, the weft insertion rate of looms is getting higher and higher. The weft insertion rate of air-jet looms has reached 2000-2500m / min, and the weft insertion rate of the latest air-jet looms has reached 3200m / min. A high weft insertion rate necessarily requires a high quality weft yarn supply. At present, the yarn guiding distance of all creels supplying weft yarns is not variable during the production process, but the actual situation is that the optimal yarn guiding distance of a full bobbin and a small bobbin is very different, and the optimal yarn guiding distance of a full bobbin is twice that of a small bobbin ,even more. When the mechanic adjusts the yarn guide distance, he can only set a yarn guide distance according to the...
