Abstract

The utility model provides a formula weft accumulator sways, include the unwrapping wire head of exporting the woof downwards, unwrapping wire head setting reciprocating motion on sways the track, be provided with under the unwrapping wire head and lead the yarn wheel pair, constantly emit the woof in the time of unwrapping wire head tremor pendulum, the woof is in with gravity because of swaing constantly descend and the expansion in storing up the screen cover, from this the resistance of woof by corrugated storage, during effective woof backing -off.

Description

A kind of swing weft accumulator

Technical field

The utility model relates to weaving auxiliary equipment field, especially, is that swing weft accumulator is used in a kind of weaving.

Background technology

In weaving process, the constant of strict control weft tension is vital for raising fabric quality.Along with developing rapidly of edge-less loom and improving constantly of filling insertion rate, more outstanding to the control problem of weft tension, the use of weft accumulator has just been arisen at the historic moment.If weft yarn is directly drawn from bobbin during wefting insertion, because wefting insertion process accounts for 120 degree to about the 180 degree times of one turn, main shaft, now the withdrawal speed of weft yarn is equivalent to 2 to 3 times into latitude rate, and wefting insertion is again interval generation, the weft unwinding be interrupted and cause weft tension to have larger fluctuation along with the continuous minimizing of bobbin unwinding radius, causes weft breakage and the various float caused by wefting insertion constantly to increase.Employ weft accumulator, weft yarn, after unwinding bobbin, is first winding on weft accumulator and stores, and then by wefting insertion, weft yarn is got off to introduce rib mouth from unwinding weft accumulator.

Tradition weft accumulator generally adopts metal creel to store weft yarn, and therefore, weft yarn also exists certain resistance after unwinding creel, is not suitable for loom and improves the speed of a motor vehicle further.

Utility model content

In order to solve the problem, the purpose of this utility model is to provide a kind of swing weft accumulator, and the resistance of this swing weft accumulator weft unwinding is less.

The utility model solves the technical scheme that its technical problem adopts:

This swing weft accumulator comprises the unwrapping wire head exporting weft yarn downwards, and described unwrapping wire head is arranged on reciprocating motion on a wobble channel, is provided with yarn guiding wheel pair immediately below described unwrapping wire head.

As preferably, described unwrapping wire head and described yarn guiding wheel between be provided with the yarn storage cover holding weft yarn.

As preferably, described yarn storage cover increases progressively downwards along the width in unwrapping wire head tremor pendulum direction.

As preferably, the upper end of described yarn storage cover is provided with the air-blast device to the lower end air-blowing of yarn storage cover.

As preferably, described yarn storage cover inwall is provided with the downward passage in direction, in described passage, is provided with air nozzle.

As preferably, described yarn storage cover is provided with conductive layer along on the both sides inwall of unwrapping wire head vibration-direction, the two poles of the earth of two-layer described conductive layer and an electrostatic generator.

The utility model has the advantage of:

Constantly release weft yarn while described unwrapping wire head tremor pendulum, described weft yarn constantly declines and expansion with gravity because waving in described yarn storage cover, and weft yarn is by corrugated storage thus, resistance during effective weft unwinding.

Accompanying drawing explanation

Fig. 1 be this swing weft accumulator face tangent plane structural representation.

Fig. 2 is the A-A structural representation of this swing weft accumulator Fig. 1 embodiment.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is further illustrated:

In the present embodiment, consult Fig. 1 and Fig. 2, this swing weft accumulator comprises the unwrapping wire head 200 exporting weft yarn 10 downwards, and described unwrapping wire head 200 is arranged on reciprocating motion on a wobble channel, is provided with yarn guiding wheel to 500 immediately below described unwrapping wire head 200.

Above-mentioned swing weft accumulator, described unwrapping wire head 200 and described yarn guiding wheel are provided with the yarn storage cover 100 holding weft yarn between 500, the width that described yarn storage cover 100 waves direction along unwrapping wire head 200 increases progressively downwards, releases rear continuous decline generation expansion to adapt to weft yarn 10 by unwrapping wire head 200.

Consult Fig. 2, described yarn storage cover 100 is made up of two pieces of narrow sides be oppositely arranged, 110,120 and two blocks of wide side plates 130.

Above-mentioned swing weft accumulator, the upper end of described yarn storage cover 100 is provided with the air-blast device 300 to yarn storage cover 100 lower end air-blowing, described air-blast device 300 is ventilated to yarn storage cover 100 by the gas-permeable nets of yarn storage cover 100 upper end, described air-blast device 300 can control the speed that weft yarn 10 declines, to control the density of yarn storage.

Above-mentioned swing weft accumulator, described yarn storage cover 100 inwall is provided with the downward passage in direction 140, air nozzle 400 is provided with in described passage, downward airflow layer is formed at the inner surface of described yarn storage cover 100 by described passage 140, prevent from weft yarn 10 and yarn storage cover 100 from producing to rub, the air-flow that passage 140 sprays simultaneously can supplement the throughput that the downward air-flow of air-blast device 300 lacks because of yarn storage cover 100 width expansion.

Above-mentioned swing weft accumulator, described yarn storage cover 100 is provided with conductive layer along on the both sides inwall 110,120 of unwrapping wire head vibration-direction, the two poles of the earth of two-layer described conductive layer and an electrostatic generator, make described weft yarn 10 in decline process, the electric charge of weft yarn 10 inside is because moving in the direction of electric field force to sensing both sides conductive layer, make the both sides bending point difference conductive layer of weft yarn 10 close, make the fluctuating range of weft yarn 10 wider.

The operation logic of above-mentioned swing weft accumulator:

Consult Fig. 1, weft yarn 10 is constantly released while described unwrapping wire head 200 waves, described weft yarn 10 constantly declines and expansion with gravity because waving in described yarn storage cover 100, by controlling the size of the downward air-flow of air-blast device 300, the density of weft yarn 10 in yarn storage cover 100 (i.e. Chu Weiliang) can be controlled, described conductive layer can control the electric charge conductive layer both sides migration in weft yarn 10, and then attracting weft yarn 10 to control the Pulse Width of weft yarn 10, the air-flow that described passage 140 sprays can prevent weft yarn 10 from contacting yarn storage cover 100.

Describedly be only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included in protection domain of the present utility model.
