AI Technical Summary
In traditional spinning spindles, excessive sliding friction between the yarn and the fixed guide ring leads to yarn breakage, poor yarn splicing points, and dimensional deviations in the finished braided sleeves, affecting product quality and production efficiency.
A rotatable first yarn guide wheel is used to replace the fixed guide ring, realizing rolling friction during the yarn output process. Combined with a double guide wheel graded drag reduction system and a precise annular groove design, frictional resistance is reduced and stable yarn tension output is maintained.
It significantly reduces yarn output resistance, decreases yarn breakage rate, improves the geometric accuracy and quality stability of braided sleeve products, reduces the risk of fiber performance degradation, and enhances production efficiency and the reliability of textile equipment.
