背景技术Background technique
随着时代的不断前进，人们对于服装面料的要求不断提高，目前纺织服装业处于一个追求时尚、多元化和高品质的时代。因此，对纺织原料的发展也提出了新的要求，其中花式纱线已逐渐进入人们的视野中，占据着不可取代的地位。花式纱线是指在纺纱和制线过程中采用特种原料、特种设备或特种工艺对纤维或纱线进行加工而得到的具有特种结构和外观效应的纱线，是纱线产品中具有装饰作用的一种纱线。花式纱的结构独特、造型灵活，色彩表现丰富，原料的使用多元化，富有创造力，这些促使花式纱线产品容易推陈出新，生产出较多差异化纺织产品，在当今追求个性化消费的时代，市场赋予了花式纱线广阔的空间。其中，段彩纱是目前研究和应用较为广泛的一种花式纱，具有多颜色组合的新风格，其不仅在纱线轴向有粗细变化，而且有不连续分布交替出现的花式色彩，呈现不规则的独特的花色效果。目前段彩纱生产主要是在传统的带有三罗拉的细纱机上改造实现，白色粗纱由中罗拉连续喂入，一种彩色辅纱由后罗拉间断喂入，两种粗纱在前罗拉出口汇合，产生段彩效果。该方法改造成本较低，效率较高，但是纱线条干均匀度较差。针对此，在中国专利“段彩纺纱传动装置(专利号：ZL200420081737.2)”中给出了一种带有四罗的段彩纱生产装置，但是该装置仍采用双粗纱喂入，同时，第一罗拉与第二罗拉仍采用同一电机控制，因而主牵伸无法自由调节。With the continuous advancement of the times, people's requirements for clothing materials continue to increase. At present, the textile and clothing industry is in an era of pursuing fashion, diversification and high quality. Therefore, new requirements have been put forward for the development of textile raw materials, among which fancy yarns have gradually entered people's field of vision and occupy an irreplaceable position. Fancy yarn refers to the yarn with special structure and appearance effect obtained by processing fiber or yarn with special raw materials, special equipment or special technology in the process of spinning and thread making. It is a decorative yarn in yarn products. A kind of yarn that works. Fancy yarn has unique structure, flexible shape, rich color expression, diversified use of raw materials, and creativity.

It not only has thickness changes in the axial direction of the yarn, but also has fancy colors that appear alternately in discontinuous distribution. Presents irregular and unique flower and color effects. At present, the production of segment colored yarn is mainly carried out on the traditional spinning frame with three rollers. The white roving is continuously fed by the middle roller, and one colored auxiliary yarn is intermittently fed by the rear roller. Segment color effect. This method has lower modification cost and higher efficiency, but the yarn dryness uniformity is poor. In view of this, in the Chinese patent "Segment Color Spinning Transmission Device (Patent No.: ZL200420081737.2)", a segment color yarn production device with four loops is provided, but this device still uses double roving feeding, and at the same time , the first roller and the second roller are still controlled by the same motor, so the main draft cannot be adjusted freely.
针对上述问题，本发明给出一种V型双牵伸纺纱装置，在后罗拉和中罗拉下部通过传动轴连接有后下胶辊和中下胶辊，实现喂入的双粗纱的双区的独立的V型结构的牵伸和喂入的控制，继而实现各种不同花式效果的纱线的生产，从而增加纱线的品种，同时V型结构的牵伸可有效提高对牵伸区内纤维的运动控制，改善成纱综合质量。In view of the above problems, the present invention provides a V-type double draft spinning device, in which the rear lower rubber roller and the middle lower rubber roller are connected through the transmission shaft at the lower part of the rear roller and the middle roller, so as to realize the dual zone of the double roving fed. The independent V-shaped structure drafting and feeding control, and then realize the production of yarns with different fancy effects, thereby increasing the variety of yarns. At the same time, the V-shaped structure drafting can effectively improve the control of Fiber motion control improves overall yarn quality.
