Constant tension pay-off device of multifunctional extra-large-stroke yarn storage device

Abstract

The invention relates to two-dimensional and three-dimensional knitting machine yarn storage devices, in particular to a constant tension pay-off device of a multifunctional extra-large-stroke yarn storage device. a yarn storage device shaft is nested a the yarn storage device shaft seat through a pay-off device bearing, the upper end of the yarn storage device shaft seat is provided with a yarn storage device shaft positioning sleeve, and the yarn storage device shaft positioning sleeve is connected with the yarn storage shaft through a key; a clutch plate base plate is sequentially arrangedin the groove at the upper end of the storage device shaft positioning sleeve from bottom to top, and a clutch plate base plate, a friction plate and a clutch plate sleeve an outer cylinder of the storage device shaft; the yarn storage device shaft is a hollow blind hole shaft, a pressure spring seat, a pressure spring and a pressure cap are nested in a hole of the yarn storage device shaft, the pressure cap is connected to the upper end of the yarn storage device shaft, the pressure spring is positioned between the pressure spring seat and the pressure cap, and a positioning clamp is connected to the top end of the pressure cap; the pressure spring seat, the yarn storage device shaft and the clutch plate are connected through pins; a yarn storage device sleeves the upper part of the yarnstorage device shaft and rotates around the yarn storage device shaft; The constant tension pay-off device has the advantages that continuous paying-off is carried out under constant tension, brakingis performed upon thread breakage with no interruption, no shaking occurs, no noise is produced, and paying-off tension is adjustable.

Description

technical field [0001] The invention relates to a yarn storage and release device of a two-dimensional and three-dimensional knitting machine, in particular to a constant tension thread release device for a multi-functional super-large-stroke yarn storage and release device. Background technique [0002] At present, the high-speed machine spindles generally used in braiding machines are usually as figure 1 As shown, it is provided with a spindle bar (1-1), a bobbin (1-2), a thread pendant (1-3), a bobbin shaft (1-4), a porcelain eye (1-5), and a spindle bar ( 1-1) is provided with a bobbin shaft (1-4), the bobbin (1-2) is set on the bobbin shaft (1-4), and the thread pendant (1-2) is set on the spindle bar (1-1 ), one end of the thread pendant (1-3) is provided with a porcelain eye (1-5), and the spindle bar (1-1) is provided with a porcelain eye (1-5), and the yarn (1-6) passes through the spindle during work. Rod porcelain eyes (1-5), then bend through the thread drop po...
