Weft accumulator is the device of the processing weft yarn on textile machine.When loom works, because weft yarn run speed is fast, directly
Connect the supply yarn from yarn group easily to break yarn, so as to influence production efficiency, the effect of weft accumulator just can be rapidly certain
The yarn of length is twined onto itself yarn drum, needs the used time to release at a terrific speed, is broken with reaching to improve weaving speed and reduce
Head rate.
In actual yarn feeding, the yarn being pre-stored on weft accumulator yarn drum pulls out through hairbrush circle.Between hairbrush circle and yarn drum
Distance, space of exactly entrying.The tension adjustment that yarn is realized in spacing regulation can also be roused by hairbrush circle and yarn simultaneously.
The fast unit of existing technology regulation hairbrush circle and yarn drum spacing as shown in Figure 1 and Figure 2, includes housing 10, dress
In the inside of housing 10 and the inner tube 20 of hairbrush coil 90, screw rod 30 are installed with, the one end of screw rod 30 is equipped with spanner 40 and end cap
302nd, the other end is stretched in inner tube 20.There is a circle convex tendon 203 that inner tube 20 is divided into exocoel 201 and inner chamber on the inwall of inner tube 20

Conjunction has nut briquetting 60, and the outline of nut briquetting 60 carries plane, and cavity cross-section and the nut briquetting 60 of inner cavity chamber 202 match,
So that nut briquetting 60 will not produce circular-rotation.The inner face 205 of convex tendon 203 relies on the phase of tension spring 50 with nut briquetting 60
Mutual closing is together.
Spanner 40 on screw rod 30 is provided with helicla flute 401 as shown in Figure 3, Figure 4, in the appearance surface helix of spanner 40, and
Hitching post 80 is installed with the inside of housing 10.When spanner 40 rotates, helicla flute 401 can be slided along 80 outer surfaces are tied down
OK, realizing spanner 40, inwardly and outwardly reciprocating screw moves.Side in the end of helicla flute 401 is provided with positioning hole 402,

It is dynamic, it is close toward the direction of yarn drum 1 with electric brush coil 90, increase pressure to yarn.But in this process, termination 301 and convex
The distance between outer face 204 of muscle 203 is more and more remote, and thus the length of tension spring 50 becomes big, and tension spring 50 is always
Compressive state, length becomes means that spring force diminishes greatly, and is constantly in variable condition, that is to say, that in hairbrush circle
When frame 90 is more proximate to yarn drum 1, actual tension becomes smaller on the contrary.This causes actual hairbrush circle unstable to the tensile force of yarn
It is fixed.
The helicla flute 401 of other spanner 40 is complicated, and arc-shaped curved surface difficulty of processing is quite big, also easily grinds during use
Damage, while the installing space of locating dowel 403 is limited, causes the mechanism service life of fast positioning short, maintenance rate is high.
