A seven-roller three-draft spinning device

technical field

The utility model relates to the technical field of spinning, in particular to a seven-roller and three-draft spinning device.

Background technique

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. These make fancy yarn products easy to introduce new ones and produce more differentiated textile products. In today's pursuit of personalized consumption In this era, the market has endowed fancy yarn with a broad space. Among them, segment colored yarn is a kind of fancy yarn that is widely researched and applied at present. It has a new style of multi-color combination. 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.

In view of the above problems, the utility model provides a seven-roller three-drawing spinning device, which uses seven drafting rollers to form three sets of independent drafting devices with a V-shaped structure in pairs on the left and right, and the respective drafting processes Parameters can be adjusted independently to increase fancy effects in fancy yarn production while improving overall yarn quality.

The drafting action of the first rear drafting zone between the stretching pairs, and then press output between the front roller and the front rubber roller, and be affected by the first front drafting zone between the first middle roller drafting pair and the front roller drafting pair The drafting effect, the second roving is fed between the second back roller and the second back rubber roller, and then passed between the second middle roller and the second middle rubber roller, and is drafted by the second back roller The drafting effect of the second rear drafting area between the second intermediate roller drafting pair and the pressing output between the front roller and the front rubber roller, and the drafting effect of the second intermediate roller drafting pair and the front roller drafting pair The drafting effect of the second front drafting zone, the third roving is fed between the third rear roller and the third rear rubber roller, and then passed between the third middle roller and the third middle rubber roller, It is drawn by the third rear drafting zone between the third rear roller drafting pair and the third middle roller drafting pair, and then passes through the pressing output between the front roller and the front rubber roller, and is drawn by the third middle roller drafting pair The drafting effect of the third front drafting area between the front roller drafting pair, the first roving, the second roving and the third roving after drafting are output after the front roller nip merges.

When spinning, the main motor drives the spindle to rotate through the spindle belt, and then drives the twist generated by the rotation of the bobbin to be transmitted from bottom to top, so that the yarn obtained after drafting rotates around its own axis, and then a mixed yarn with a certain twist is obtained. The obtained mixed yarn is wound on the bobbin after being passed through the yarn guide hook and the traveler. The rotation of the bobbin drives the traveler to rotate around the steel ring. Since the speed of the traveler is smaller than the speed of the bobbin, the mixed yarn is continuously wound on the bobbin. .

The utility model adopts seven drafting rollers to form three sets of independent drafting devices with a V-shaped structure in pairs, and the respective drafting process parameters can be adjusted independently, thereby increasing the fancy effect in fancy yarn production, At the same time, the comprehensive quality of yarn is improved.
