A device for removing yarn hairiness with precise direction and selective selection

Abstract

The invention relates to a directed accurate selection type yarn hairiness removing device and belongs to the technical field of textile processing. According to the directed accurate selection type yarn hairiness removing device, an adjusting slide block is movably arranged in a rectangular through slot of a fixing plate, an air inlet groove is opened in the middle of the adjusting slide block, the plane with the air inlet of the air inlet groove is parallel to the plane with a first yarn guide wheel groove and a second yarn guide wheel groove, an air blowing seat is corresponding to the adjusting slide block, and compressed air current enables the yarn hairiness to stretch in a directed blowing mode; a locating bolt is arranged between the adjusting slide block and the rectangular through slot, a resistance wire is arranged in the air inlet groove in the middle of the adjusting slide block, the resistance wire is located in the projection of one end of the air outlet of an air conveying pipeline on the adjusting slide block, the vertical distance between the yarn trunk and resistance wire can be precisely adjusted in the range of 1 to 3 millimeters, the harmful hairiness section is precisely selected to remove from the hairiness which spreads and straightens in the fixed direction by means of the resistance wire, and the beneficial hairiness is reserved. The directed accurate selection type yarn hairiness removing device is simple and reasonable in structure, convenient to operate and easy to popularize and use.

Description

technical field [0001] The invention relates to a device for removing yarn hairiness with precise direction and selection, and belongs to the technical field of textile processing. [0002] technical background [0003] Yarn hairiness refers to the fiber end or fiber ring exposed on the surface of staple fiber yarn. When the yarn is stressed, the hairiness lacks a gripping force point, which does not help the yarn strength; and if the yarn hairiness is too much, the friction of the yarn increases, and the yarn is more likely to be worn and broken in subsequent processing, which affects the processing efficiency; During the process, yarns with too much hairiness tend to get entangled together, resulting in unclear shedding, which affects weaving efficiency and quality. Yarn hairiness also affects the appearance quality of the final product. Therefore, hairiness has always been one of the important indicators of yarn quality that textile enterprises are most concerned about. ...

Problems solved by technology

[0012] Due to the adoption of the above technical scheme, compared with the prior art, a device for removing hairiness of yarns with precise orientation and selective selection according to the present invention has the advantage that: the device of the present invention adopts a rectangular through slot in the middle of the working surface of the fixing plate, The adjustment slider is movably installed in the rectangular slot of the fixed plate. There is an air inlet slot in the middle of the adjustment slider. The air inlet of the air inlet slot is in the shape of a rounded rectangle. The plane where the wheel groove of the second wire guide wheel is parallel, the blowing seat corresponds to the adjustment slider, and there is an air pipeline in the middle of the blowing seat, and the air pipeline is connected to the air compressor through the guide pipe. The function of stretching the yarn hairiness makes the yarn running to the center of the air inlet in a tensioned manner, the yarn trunk is tensioned, and the hairiness on the surface of the yarn is stretched and straightened in the air inlet slot on the vertical center of the air inlet ;The adjustable slider is installed in the rectangular slot of the fixed plate, and the positioning bolt is set between the adjustable slider and the rectangular slot, and the resistance wire is set in the air inlet slot in the middle of the adjustment slider, and is located On the side of the air inlet, the resistance wire is located in the projection of the air outlet end of the air pipeline on the adjustment slider", so that the vertical distance between the yarn trunk and the resistance wire can be precisely adjusted within the range of 1-3 mm. Finally, the directional stretched surface hairiness is accurately and selectively removed under the action of high-temperature resistance wire, and the harmful hairiness section whose length is longer than the vertical distance between the yarn Y main body and the resistance wire is accurately and effectively removed by the resistance wire, solving the problem of The technical problem of "the prior art uses lodging and re-wrapping in a loose form to fit the yarn hairiness, and the reduced hairiness of the yarn is easy to rebound again after friction"; at the same time, the length is less than or equal to the vertical distance between the yarn trunk and the resistance wire The beneficial hairiness is all preserved, and the harmful hairiness on the yarn surface is selectively removed, which fundamentally eliminates the hairiness reduction technology involved in the process of spinning, winding, warping, singeing, etc., just blindly and simply , Indiscriminately reduce yarn hairiness, unable to implement the technical disadvantages and shortcomings of eliminating harmful hairiness and retaining beneficial hairiness on yarn
