Abstract
The utility model provides an auxiliary picking structure which comprises a foreign-shaped reed that is arranged between an upper crossbeam and a lower crossbeam. The foreign-shaped reed is composed of an upper reed strip, a reed grooved magnetic sheet with an arc edge, and a lower reed strip from top to bottom. The lower edge of the upper reed strip and the upper edge of the lower reed strip form the groove edge of the reed groove of the foreign-shaped reed. The arc edge of the reed grooved magnetic sheet forms the bottom of the reed groove. A first metal strip and a second metal strip respectively cover the lower edge of the upper reed strip and the upper edge of the lower reed strip. The first metal strip and the second metal strip are respectively connected with two poles of an electrostatic generator. The reed grooved magnetic sheet is internally provided with a magnet. A metal nozzle of a weaving machine is connected with a same electrostatic generator electrode of the second metal strip. According to the auxiliary picking structure, the weft yarn with electric charges overcomes gravity through an electric field force and a Lorentz force, thereby improving weft insertion precision.
Description
Affiliated technical field
The utility model relates to air-jet loom field, especially, is a kind of auxiliary picking structure that is applicable to air-jet loom.
Background technology
A good loom should reach high-quality, high yield, low consumption, environmental protection, and the key of head it off is to improve constantly the hard waste rate that enters latitude rate, minimizing weft yarn, elimination crapand, minimizing strut rail, reduction noise, the raising Automated water equality of loom.Along with improving constantly of loom speed, absolute time for wefting insertion is very short, in wefting insertion process, weft carrier in a short period of time weft traction accurately passes through whole shed open reposefully, the heavy shuttle wefting insertion that has obviously not too adapts to, therefore the application of the novel filling insertion way such as projectile shuttle, arrow shaft, jet, water spray is more and more general.
Pneumatic picking mechanism mainly comprises main burner and pilot jet, anti-airflow diffuser, air supply system.Anti-airflow diffuser mainly contains two kinds, and one is confuser, and another kind is special-shaped reed.Confuser composition pipeline, between confuser, to leave gap to hold warp thread, at the de-yarn groove of radially having of confuser, to complete after wefting insertion, weft yarn is deviate to stay in shed open from pipeline, the opening portion of confuser top, after completing for wefting insertion, weft yarn de-yarn groove from confuser is deviate from and stays in shed open.Special-shaped reed also claims groove reed, and main burner is aimed at reed groove, and the air-flow weft traction of ejection passes through shed open in the groove of this special dent.No matter be confuser or make special-shaped reed, weft yarn is kept away unavoidably because gravity sinks in crossing process, if the speed of wefting insertion is fast not, this sinking meeting directly affects the accuracy of wefting insertion, causes the accident of sluff-offs.
Utility model content
In order to address the above problem, the purpose of this utility model is to provide a kind of auxiliary picking structure, and when this auxiliary picking structure can effectively prevent picking, weft yarn declines.
The utility model solves the technical scheme that its technical problem adopts:
This auxiliary picking structure comprises the Profiled Reed being arranged in lower and upper cross-member, described Profiled Reed is divided into reed bar from top to bottom, reed groove magnetic sheet with curved edge and lower reed bar, the groove edge that forms below Profiled Reed reed groove with the top of described lower reed bar of described upper reed bar, the curved edge of described reed groove magnetic sheet forms the bottom land of reed groove, following and the top of described lower reed bar of described upper reed bar is coated with respectively the first bonding jumper and the second bonding jumper, described the first bonding jumper and the second bonding jumper are connected respectively the two poles of the earth of electrostatic generator, in described reed groove magnetic sheet, be provided with magnet, the metallic nozzle of loom is connected on the electrostatic generator electrode that the second bonding jumper is identical.
As preferably, the magnet in described reed groove magnetic sheet is electromagnet.
As preferably, the curved edge center of described reed groove magnetic sheet is provided with conductive layer, described conductive layer ground connection.
As preferably, described conductive layer is the irony after magnetization.
The utility model has the advantage of:
The electric field force that the first bonding jumper and the second bonding jumper form, make weft yarn overcome a part of gravity, and the impact that the magnetic field that reed groove magnetic sheet forms makes weft yarn be subject to long-range navigation thatch power makes weft yarn overcome another part gravity, weft yarn is not affected by gravity in the time of wefting insertion, improve into latitude precision.
Brief description of the drawings
Fig. 1 is the structural representation of this auxiliary picking structure.
Fig. 2 is the structural representation of this auxiliary picking structure reed slotted vane.
Fig. 3 is the schematic diagram that this auxiliary picking structure is subject to electric field force and the impact of long-range navigation thatch power.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated:
In the present embodiment, consult this auxiliary picking structure of Fig. 1 and Fig. 2 and comprise the Profiled Reed 100 being arranged in lower and upper cross-member 300, weft yarn 10 passes through the reed groove of described Profiled Reed 100 under the guiding of air-flow, described Profiled Reed 100 is divided into reed bar 110 from top to bottom, reed groove magnetic sheet 200 with curved edge and lower reed bar 120, the groove edge that forms below Profiled Reed 100 reed grooves with the top of described lower reed bar 120 of described upper reed bar 110, the curved edge of described reed groove magnetic sheet 200 forms the bottom land of reed groove, following and the top of described lower reed bar 120 of described upper reed bar 110 is coated with respectively the first bonding jumper 111 and the second bonding jumper 121, described the first bonding jumper 111 and the second bonding jumper 121 are connected respectively the two poles of the earth of electrostatic generator, in described reed groove magnetic sheet 200, be provided with magnet, the metallic nozzle of loom is connected on the electrostatic generator electrode that the second bonding jumper is identical.
Above-mentioned auxiliary picking structure, the magnet in described reed groove magnetic sheet 200 is electromagnet, by the magnetic field intensity of regulating magnet, can adjust weft yarn 10 and be subject to the size of long-range navigation thatch power, to adapt to the weft yarn 10 of unlike material.
Above-mentioned auxiliary picking structure, the curved edge center of described reed groove magnetic sheet 200 is provided with conductive layer 210, described conductive layer 210 ground connection, after wefting insertion operation completes, weft yarn 10 is by the operation of beating up, while beating up, described conductive layer 210 is squeezed into weft yarn 10 in the fell of warp thread formation, and conductive layer 210 is removed the static on weft yarn 10.
