A doubling device with pretension function

Abstract

The invention discloses a doubling device with a pretension function. According to the technical scheme, the doubling device is characterized in that a substrate is included, and a doubling plate is arranged in the middle of the substrate; a plurality of yarn guide points are arranged in the position, on the periphery of the doubling plate, of the substrate; pretensioners for providing tension for yarn out of the yarn guide points are arranged in the position, corresponding to the yarn guide points, above the substrate; doubling points for combining multiple strands of yarn out of the pretensioners into plied yarn are arranged on the doubling plate. The disc type pretensioners are arranged on fixed plates, and composed of tension discs, disc sheets, weights, yarn guide rods and the like. Yarn penetrates through clearances of the tension discs and the disc sheets, and the tension of each strand of yarn can be adjusted by adding or reducing the weights so as to guarantee that the tension of all the yarn is consistent. Yarn hairness can be removed and floating yarn hairness can be reduced to a certain degree through the pretension function.

Description

【Technical field】 [0001] The invention relates to a yarn doubling winder, in particular to a yarn doubling device with a pretension function applied to the yarn doubling winder. 【Background technique】 [0002] The winding machine is a special equipment for the textile industry. As the last process of spinning and the first process of weaving, winding plays an important role in the textile field. Existing doubling and winding machines generally combine two or three strands of yarn together, and then bond the multiple strands of yarn into ply yarns by two-for-one twisting. But most of existing doubling devices are simple in structure, single in function and low in performance, and they simply play the most basic role of merging multiple strands of yarn together. Various problems such as inconsistent yarn tension, large yarn wear, and yarn breakage often occur, resulting in low work efficiency, high energy consumption, and unqualified product quality, which affects the compre...

Problems solved by technology

However, most of the existing yarn doubling devices have simple structures, single functions, and low performance, and only play the most basic role of combining multiple yarns together.

Various problems such as inconsistent yarn tension, large yarn wear, and yarn breakage often occur, resulting in low work efficiency, high energy consumption, and unqualified product quality, which affects the comprehensive benefits of the production enterprise
