LOWER SPINNING ASSEMBLY OF FIBER STRAND CONVEYING MECHANISM OF RING SPINNING FRAME
Document Type and Number:
WIPO Patent Application WO/2022/262567
Kind Code:
A1
Abstract:
A lower spinning assembly of a fiber strand conveying mechanism of a ring spinning frame, comprising a lower supporting member and a lower spinning block (57). The lower spinning block (57) is detachably connected to the lower supporting member; and an upper arc-shaped surface of the lower spinning block (57) supports yarns or an upper arc-shaped surface composed by the upper arc-shaped surface of the lower spinning block (57) together with the lower supporting member supports the yarns. A gap and a curve formed by a fiber strand passing through the gap are changed by changing the arc-shaped surface of the spinning block (57), so that the conversion of a working arc-shaped surface of the lower spinning assembly is facilitated, and a spinning yarn levelness index is optimized; a collection recess (5731) is provided on the spinning block, such that a yarn hairiness index is improved; and carding recesses (5761, 5771) are provided on the spinning block, such that the requirements of siro spinning and solo spinning are met.
