The lower side of the upper reed strip and the upper side of the lower reed strip form the edge of a profiled reed groove, and the cambered edge of the reed groove magnetic sheet forms the bottom of the reed groove. The lower side of the upper reed strip and the upper side of the lower reed strip are covered with a first metal strip and a second metal strip respectively, and the first metal strip and the second metal strip are connected with two electrodes of an electrostatic generator respectively. A magnet is arranged in the reed groove magnetic sheet, and a metal nozzle of a loom is connected the electrostatic generator electrode which is connected with the second metal strip. According to the structure, electric field force and Lorentz force are used for enabling weft yarns with charges to overcome gravity, so that the weft feeding accuracy is improved.
Description
Art
The present invention relates to air-jet loom field, especially, is a kind of auxiliary picking structure being 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 be to improve constantly loom the hard waste rate entering latitude rate, reduce weft yarn, eliminate crapand, reduce strut rail, reduce noise, improve Automated water equality.Along with improving constantly of loom speed, absolute time for wefting insertion is very short, in wefting insertion process, weft carrier accurately will pass through whole shed open by weft traction in a short period of time 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, gap to be left to hold warp thread between confuser, de-yarn groove is had in the radial direction of confuser, so that after completing wefting insertion, weft yarn is deviate to stay in shed open from pipeline, opening portion above confuser, 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 accuracy sinking can directly affect wefting insertion, causes the accident of sluff-offs.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of auxiliary picking structure, when this auxiliary picking structure effectively can prevent picking, weft yarn declines.
The technical solution adopted for the present invention to solve the technical problems is:
This auxiliary picking structure comprises the Profiled Reed be 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, following and the top of described lower reed bar of described upper reed bar forms the groove edge of Profiled Reed reed groove, 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 the first bonding jumper and the second bonding jumper respectively, described first bonding jumper and the second bonding jumper are connected the two poles of the earth of electrostatic generator respectively, magnet is provided with in described reed groove magnetic sheet, the metallic nozzle of loom is connected on the identical electrostatic generator electrode of the second bonding jumper.
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 invention has the advantages that:
The electric field force that first bonding jumper and the second bonding jumper are formed, weft yarn is made to overcome a part of gravity, and the impact that the magnetic field that reed groove magnetic sheet is formed makes weft yarn be subject to Lorentz force makes weft yarn overcome another part gravity, weft yarn is not affected by gravity when wefting insertion, improves into latitude precision.
Accompanying drawing explanation
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 Lorentz force impact.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
In the present embodiment, consult this auxiliary picking structure of Fig. 1 and Fig. 2 and comprise the Profiled Reed 100 be 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, following and the top of described lower reed bar 120 of described upper reed bar 110 forms the groove edge of Profiled Reed 100 reed groove, 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 the first bonding jumper 111 and the second bonding jumper 121 respectively, described first bonding jumper 111 and the second bonding jumper 121 are connected the two poles of the earth of electrostatic generator respectively, magnet is provided with in described reed groove magnetic sheet 200, the metallic nozzle of loom is connected on the identical electrostatic generator electrode of the second bonding jumper.
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 the size that weft yarn 10 is subject to Lorentz force, 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 will carry out the operation of beating up, when beating up, weft yarn 10 is squeezed in the fell of warp thread formation by described conductive layer 210, and the electrostatic on weft yarn 10 is removed by conductive layer 210.
Above-mentioned auxiliary picking structure, described conductive layer 210 is the irony after magnetization, makes conductive layer 210 not affect the magnetic field of reed groove magnetic sheet 200.
The working method of above-mentioned auxiliary picking structure:
Consult Fig. 2 and Fig. 3, the weft yarn 10 of static electrification sprays by the metallic nozzle of loom, weft yarn 10 is through the reed groove of Profiled Reed 100, the electric field force that first bonding jumper 111 and the second bonding jumper 121 are formed, weft yarn 10 is made to overcome a part of gravity, and the impact that the magnetic field that reed groove magnetic sheet 200 is formed makes weft yarn 10 be subject to Lorentz force makes weft yarn 10 overcome another part gravity, weft yarn 10 is not affected by gravity when wefting insertion, improves into latitude precision.
