A yarn feeding device capable of adjusting the density of yarn division

Abstract

The invention discloses a yarn conveying device capable of adjusting the yarn-dividing density, and relates to the technical field of textiles. The yarn conveying device comprises a yarn conveying wheel and a yarn-dividing device. The yarn-dividing device comprises a core bar which is divided into an upper core bar section, a middle core bar section and a lower core bar section from top to bottom. The center axis of the upper core bar section in the bar length direction is a vertical line, the center axis of the middle core bar section and the center axis of the lower core bar section in the bar length direction are located on the same straight line, the center axis of the middle core bar section and the center axis of the lower core bar section deviate from the vertical line, and an included angle exists between the center axes of the middle core bar section and the lower core bar section and the vertical line. A device enabling the core bar to rotate with the upper core bar section as an axis is arranged so that the core bar can rotate with the upper core bar section as the axis. Yarn wound on the yarn conveying wheel can be arranged according to the thickness and the density by rotating a handle and the core bar, and it is ensured that the yarn on the yarn conveying wheel can be wound by 12 to 16 circles in order and cannot slide. A yarn-dividing sleeve is provided with a bearing, the yarn walk freely on the surface of the yarn-dividing sleeve and the surface of the yarn conveying wheel, the kinetic friction force to the yarn from the yarn-dividing sleeve and the yarn conveying wheel is very small, and the quality of a woven product can be improved easily.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a yarn feeding device capable of adjusting the density of divided yarns. Background technique [0002] The main component of the yarn feeding device of the circular knitting machine is the yarn feeding wheel (also known as the yarn storage tube). It has three functions: first, the function of yarn storage, the yarn is sent to the yarn feeding wheel through the yarn inlet eye of the clamping and filtering mechanism, and wound on the yarn feeding wheel for storage; The yarn is neatly and orderly wound round by round on the yarn feeding wheel, and cannot be piled up, and the yarns of each circle cannot be pressed against each other, so that it is easy to send out from the subsequent yarn guide eye; thirdly, the yarn can be adjusted according to the thickness of the yarn. The density of the yarns arranged on the yarn feeding wheel, if the yarn is thin, it will be arranged more tigh...

AI Technical Summary

Problems solved by technology

However, this technical solution has some defects: 1) It is inconvenient and inconvenient to manually wrap the yarn on the yarn feeding wheel and the yarn dividing rod at the beginning of the operation; 2-3 rounds of yarn, if there is more, the yarn will slip on the yarn feeding wheel, and the stability of yarn feeding will be lacking

By arranging the yarn guide rod 70, the frictional resistance between the yarn and the surface of the yarn feeding wheel 30 is reduced, but the yarn guide rod 70 is fixed, and the tension of the yarn wound on the yarn feed wheel 30 is relatively large, and the yarn and the yarn feeding wheel The friction force on the surface of the wheel 30 is still relatively large, which will damage the gloss of the yarn surface and affect the quality of the weaving product.
