Abstract
The invention discloses a reed plate, which comprises a reed plate body. An airflow reed groove is formed in the middle of the reed plate body, an upper inner cavity is arranged in the upper half portion of the reed plate body, one end of the upper inner cavity is an upper air inlet which is arranged at the joint of the top end of the upper half portion of the reed plate body and an upper reed beam, the other end of the upper inner cavity is an upper nozzle which is arranged at the bottom end of the upper inner cavity, and airflow passes through the upper inner cavity from the upper air inlet and is ejected out from the upper nozzle to the airflow reed groove. A lower inner cavity is arranged in the lower half portion of the reed plate body, one end of the lower inner cavity is a lower air inlet which is arranged at the joint of the bottom end of the lower half portion of the reed plate body and a lower reed beam, the other end of the lower inner cavity is a lower nozzle which is arranged at the top end of the lower inner cavity, and the airflow passes through the lower inner cavity from the lower air inlet and is ejected out from the lower nozzle to the airflow reed groove. Ejecting airflow formed in the inner cavity of the reed plate is used as auxiliary airflow, so that capability of the ejecting airflow for crossing the integral reed plate is enhanced.
Description
Technical field
The invention belongs to the loom field, relate to air-jet loom, relate to the reed wire that a kind of air-jet loom uses specifically.
Background technology
In air-jet loom, the main jet air-flow has only 40cm to the effective range of wefting insertion yarn, and working-cloth width is at 200-400 cm.After length of yarn was greater than 40cm, the weft yarn tractive force that the main jet air-flow produces no longer increased.Therefore after 40cm; needs follow-up air-flow; The tractive force that acts on the leading end is decayed because of air-flow falls, and secondary air is the effective means of replenishing Wefting insertion in-slot air flow, and the secondary air that only relies on pilot jet to provide in the prior art can't reach preferable effect.
Represent the reed wire that air-jet loom uses in the prior art referring to Fig. 1.What use on the air-jet loom now is solid reed wire.
Summary of the invention
The present invention aims to provide a kind of reed wire, and this reed wire can provide secondary air to help weft yarn and leap reed width.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention realizes through following technical scheme:
A kind of reed wire; Comprise a reed wire body; Said reed wire body middle part constitutes air-flow reed groove, is provided with inner chamber in the first half of said reed wire body, and a said end of going up inner chamber is positioned at said the first half top and last reed beam connection place is last air inlet; It is last spout that the other end is positioned at said upward inner chamber bottom, and air-flow sprays entering said air-flow reed groove through the said inner chamber of going up from the said spout of going up from said upward air inlet; Be provided with a lower inner cavity in the latter half of said reed wire body; One end of said lower inner cavity is positioned at said the latter half bottom and is following air inlet with following reed beam connection place; The other end is positioned at said lower inner cavity top and is following spout, and air-flow gets into said air-flow reed groove through said lower inner cavity from the ejection of said spout down from said air inlet down.
Further, the angle of the end face of the air-flow exit direction of said upward spout and said air-flow reed groove is less than 45o.
Further, the angle of the bottom surface of the air-flow exit direction of said spout down and said air-flow reed groove is less than 45o.
Further, the wall thickness of said reed wire body is greater than 0.08mm.
Further, the material of said reed wire body is a pottery.
Reed wire is very thin, and the cross section of reed wire inner chamber and jet is less, and therefore the jet-stream wind from the reed wire ejection has at a high speed.The characteristics of secondary injection air-flow are to connect in proper order to draw, and a lot of distribution densities of reed wire are high again, and the high velocity air that produces from reed wire is desirable secondary injection air-flow.The back of the body that has largely remedied weft tracting flow from the jet-stream wind of reed wire is let out and preceding leakage.The speed that weft yarn leaps the reed groove depends on the order opening time of pilot air and the speed of air-flow, and emphasis is to guarantee that weft yarn leaps the speed of shed open.
Compared with prior art, the present invention has following beneficial effect:
The present invention utilizes the reed wire inner chamber to produce one jet-stream wind through air-flow, and a kind of as secondary air increased the ability of the jet-stream wind of crossing over whole reed width.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. detailed description.The specific embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
