A large-stroke frictionless spindle of a braiding machine

Abstract

The invention provides a large-stroke friction-free spindle mechanism of a braider, belonging to spindle mechanisms of braiders. The spindle comprises a lower yarn passing wheel, a plummet, a spindle blade, an upper yarn passing wheel, a threading sleeve, a take-up and pay-off device, a clamp spring, a bobbin shaft, a faceplate, a tensioner, a lifting pin and a pressure spring, wherein the plummet is connected below the spindle blade; the lifting pin and the pressure spring are connected to the spindle blade at one end of the plummet; the lower yarn passing wheel is connected at the other end of the plummet; the faceplate is arranged in the middle of the spindle blade; the bobbin shaft is arranged in the center of the faceplate and is connected with the spindle blade into a whole; the tensioner is connected between the faceplate and the spindle blade; the upper yarn passing wheel is connected in the middle of one side of the spindle blade; the threading sleeve is connected above one side of the spindle blade; one end of the take-up and pay-off device is connected to the bobbin shaft by the clamp spring and the other end of the take-up and pay-off device is hinged with the top end of the spindle blade. The spindle has the advantages that the pay-off stroke of the spindle is increased by adopting the rolling and take-up modes, so the spindle is suitable for two-dimensional and three-dimensional guide rail braiders; yarn surfaces are friction-free and yarn material surfaces are not damaged, thus increasing the product quality and yield.

Description

technical field [0001] The invention relates to a spindle of a braiding machine, in particular to a large-stroke frictionless spindle of a braiding machine. Background technique [0002] The high-speed machine spindles generally used on braiding machines, such as figure 1 As shown, including: spindle rod (1-1), bobbin (1-2), thread pendant (1-3), bobbin shaft (1-4), porcelain eye (1-5), brake cutting shaft ( 1-7), brake cutting shaft horizontal pin (1-8), face plate (1-9), outlet hole (1-10) and wire pendant porcelain eye (1-11); There is bobbin shaft (1-4), bobbin (1-2) is sleeved on bobbin shaft (1-4), thread pendant (1-3) is stuck on both sides of spindle bar (1-1), thread pendant (1-3) One end is provided with thread drop porcelain eyes (1-11), and the spindle bar (1-1) is provided with porcelain eyes (1-5). When working, the yarn (1-6) passes through the spindle bar porcelain eyes ( 1-5), and then bent to the outlet hole (1-10) through the thread drop porcelain eye (...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a large-stroke frictionless spindle of a knitting machine, which solves the problem of large friction of the existing spindle, easy wear and tear on the surface of the yarn, labor-intensive unwinding, and short stroke of the thread drop, making it uneven in weaving and fine yarns. breakable problem
