A seamless underwear machine equipped with a spandex bobbin fixing bracket

Abstract

The invention discloses a seamless underwear machine with a spandex yarn tube fixing support, and belongs to the technical field of textile machines. The seamless underwear machine comprises a yarn conveying mechanism, a weaving mechanism, a pulling and batching mechanism and a transmission control mechanism. The yarn conveying mechanism comprises a yarn support, a steel rod and a conveyor, the steel rod is arranged on the yarn support, yarn tubes can be inserted in the steel rod, and the conveyor is used for conveying yarns. The seamless underwear machine is characterized in that the spandex yarn tube fixing support is arranged on the yarn support, and the yarns can be stably conveyed by the spandex yarn tubes under the control of the spandex yarn tube fixing support. The seamless underwear machine has the advantages that shortcomings of blistering, wrinkling and unevenness of woven seamless underwear due to the fact that spandex yarn tubes on a steel rod originally arranged on an existing seamless underwear machine jump abnormally and spandex yarns with high smoothness are conveyed unstably can be overcome, and accordingly spandex yarns can be completely mixed and woven by the existing seamless underwear machine to obtain intermediate-grade seamless underwear in China.

Description

technical field [0001] The invention belongs to the technical field of textile machines, and in particular relates to a seamless underwear machine provided with a spandex bobbin fixing bracket. Background technique [0002] The seamless underwear machine is the main textile machine for underwear production. The seamless underwear textile machines owned by my country account for 45% of the world. The seamless underwear produced is a pillar industry of the underwear industry. The seamless underwear machine has the advantages of fast production speed, With the characteristics of high efficiency and high technological content, the underwear produced by it is generally favored by the majority of women. At present, there is still a certain gap between the medium-grade seamless underwear produced in my country and the seamless underwear produced in foreign countries, and a large part of the medium-grade seamless underwear is made of elastic materials that can be stretched 5-8 times ...

Problems solved by technology

At present, there is still a certain gap between the medium-grade seamless underwear produced in my country and the seamless underwear produced in foreign countries, and a large part of the medium-grade seamless underwear is made of elastic materials that can be stretched 5-8 times and are not easy to age. Spandex mixed weaving, and the existing seamless underwear machine uses spandex mixed weaving, which will cause uneven and asymmetric spandex yarns of the seamless underwear, resulting in blistering, wrinkling, and unevenness of the seamless underwear

According to the long-term research of Zhejiang Textile Technology Co., Ltd., the above-mentioned disadvantages are because spandex is a kind of polyurethane elastic fiber, which has great slipperiness and strong fluctuation, and it is difficult to control its stable feeding during the wire feeding process. Wire

The existing spandex thread feeding is to insert the spandex bobbin on the steel rod of the yarn support on the seamless underwear machine, and then transport the spandex yarn to the weaving mechanism of the seamless underwear machine through the conveyor; The hole diameter is relatively large, about 10 cm, while the diameter of the steel rod is only 1 cm. When the spandex bobbin is directly placed on the steel rod, as the loom runs, the spandex yarn pulls the spandex bobbin to rotate, and the spandex bobbin The jump on the steel rod is very large. When the running speed of the loom reaches 90 revolutions per minute, because the spandex is extremely slippery, the abnormal jump of the spandex bobbin directly affects the normal introduction of the spandex yarn into the conveyor, and it is sometimes loose and sometimes tight. The spandex yarns of the woven seamless underwear are uneven and asymmetrical, resulting in blistering, wrinkling, and unevenness of the seamless underwear

Because of the above reasons, our country can't use the existing seamless inner machine to weave medium-grade seamless underwear with spandex mixed weaving.
