Three-roller positive double-core core-spun yarn production device

Abstract

The invention discloses a three-carrier roller positive production device used for a twin-core core-spun yarn and installed on a spinning frame in textile industry. The three-carrier roller positive production device used for the twin-core core-spun yarn comprises a cross beam and a godet roller arranged below the cross beam, and also comprises a carrier roller III and a rubber covered roller, wherein the carrier roller III is arranged on the cross beam, and the rubber covered roller is externally tangent to the carrier roller III; a jaw for a second core silk to pass through is formed between the carrier roller III and the rubber covered roller; the carrier roller III rotates around the axis of the carrier roller III under the driving action of a driving motor; the second core silk passes through the jaw formed by the carrier roller III and the rubber covered roller, and then, is led into jaws of front rollers and front rubber covered rollers of the spinning frame by the godet roller. According to the three-carrier roller positive production device used for the twin-core core-spun yarn, disclosed by the invention, on the basis of an existing first core silk tensioner, a tensioner for the second core silk is additionally arranged; the carrier roller III is independently driven by the driving motor, and the tension of the second core silk can be adjusted by changing a gear or directly adjusting the speed of the motor, and therefore, the tension of the second core silk is adjustable, and the defect, which is likely to occur, that an original twin-core yarn is poor to coat poor or elasticity is not stable can be eliminated.

Description

Technical field [0001] The invention relates to a production device for core-spun yarn, in particular to a three-roller active double-core core-spun yarn production device. Background technique [0002] At present, in the spinning process of the textile industry, one or two chemical fibers with special properties are often added to the yarn, and the original yarn is wrapped in the yarn core to form a single-core yarn or a double-core yarn to improve the yarn performance. performance. [0003] Traditional production equipment for double core yarn figure 1 As shown, it includes a cross beam 7, an idler 9 and a second idler 8 mounted on the cross beam 7. A godet wheel 11 and three sets of rollers are arranged under the beam 7 and each set of rollers is composed of rubber rollers and rollers. During production, the spandex yarn 10 is unwound under the active drive of idler 2 8 and idler 9 and is guided by the guide wheel 11 into the jaws of the front roller 14 and the front rubber rol...

AI Technical Summary

Problems solved by technology

During production, the spandex yarn 10 is unwound under the positive drive of the supporting roller 2 8 and the supporting roller 1 9, and under the guidance of the godet 11, enters the jaws of the front roller 14 and the front rubber roller 12 of the spinning frame; The core yarn 2 of another chemical fiber can only be wrapped in the yarn core under the control of free or external non-positive tensioner, so the produced double-core yarn is prone to the disadvantages of poor covering or unstable elastic force
