Abstract
The invention provides a weft catching and cutting device of a weaving machine. The weft catching and cutting device comprises a cutting component, a conductive weft yarn injection orifice and a deviation correction ring arranged at the weft catching end. Weft yarn passes through the deviation correction ring. The deviation correction ring is composed of two arc-shaped bars with coincident axes. Two gaps are formed between the end faces of the two arc-shaped bars. The inner sides of the arc-shaped bars are provided with conducting layers. The cutting component is composed of two cutting bars, wherein the tip ends of the two cutting bars swing and pass through the two gaps respectively. The cutting bars separate and close on the motion trail of the weft yarn through reciprocating swing. When the weft yarn passes through the deviation correction ring, the cutting bars are located in the gaps. The tip ends of the cutting bars are provided with conducting plates. The conducting layers, the conducting plates and the conductive weft yarn injection orifice are all electrically connected with a pole of an electrostatic generator. According to the weft catching and cutting device, the arc-shaped bars and the conducting plates on the cutting bars have the same electric charge as the weft yarn and are arranged around the weft yarn so that the position of the weft yarn can be corrected before weft catching.
Description
Art
The present invention relates to textile machine apparatus field, especially, be a kind of shuttleless loom catch latitude cutter sweep.
Background technology
Shuttleless loom is after fly-shuttle loom, a kind of new loom of birth.Shuttleless loom is separated from shuttle at weft yarn package, or only carrying a small amount of weft yarn replaces massive shuttle with small and light weft insertion device, for high speed wefting insertion provides favourable condition.In the supply of weft yarn, directly adopt package again, enter weft insertion device, loom is broken away from weft replenishment action frequently by storage Weft handling device.Therefore, adopt shuttleless loom for increase fabric variety, adjust fabric construction, reduce fabric defects, improve fabric quality, reduce noise, improve working conditions significant.The shuttleless loom speed of a motor vehicle is high, usually than fly-shuttle loom efficiency height 4-8 doubly.
The mode clipped weft yarns such as shuttleless loom employing is sprayed water, jet carry out picking operation, the accuracy of its flight path is kept by the mechanical structure that the weft yarn clamped is unfixing, therefore the flight of shuttleless loom weft yarn is easily subject to various interference, and this has efficient weft yarn trap setting accurately to catch weft yarn with regard to requiring at the end of weft yarn flight path.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of loom to catch latitude cutter sweep, latitude cutter sweep caught by this loom accurately can catch weft yarn.
The technical solution adopted for the present invention to solve the technical problems is:
This loom is caught latitude cutter sweep and is comprised shear component, conductive warp yarns jet and be arranged on the correction ring of catching latitude end, weft yarn movement locus is by described correction ring, described correction ring is made up of the arc bar of two axis coincidings, described arc bar is symmetrical along axle center, article two, form two gaps between described arc bar end face, the inner side of described arc bar is provided with conductive layer, described shear component is made up of the slitting of two tip oscillation respectively through two described gaps, described slitting distributes along the axisymmetrical of described arc bar, described slitting is separated by reciprocally swinging and closes on weft yarn movement locus, when weft yarn is by described correction ring, described slitting is positioned at described gap, described slitting is closed behind described gap, the tip of described slitting is provided with conducting strip, described conductive layer, conducting strip and conductive warp yarns jet are all electrically connected with a pole of an electrostatic generator.
As preferably, when described slitting is positioned at described gap, described conducting strip parallels with weft yarn transmission locus.
As preferably, the width at described slitting tip is more than 1.1 times of diameter of the weft yarn.
The invention has the advantages that:
Weft yarn is static electrification lotus after described conductive warp yarns jet, when weft yarn enters described correction ring, described arc bar is with identical electric charge on the conducting strip band yarn on slitting and be periphery around yarn, correct to described correction ring axe movement under the effect that yarn repels at like charges electrostatic force, described slitting swings, and the tip of slitting is near catching weft yarn, when slitting contacts completely, weft yarn is truncated, and the position of weft yarn before catching latitude is corrected.
Accompanying drawing explanation
Fig. 1 is that the not closed side-looking structural representation of latitude cutter sweep slitting caught by this loom.
Fig. 2 is that the closed side-looking structural representation of latitude cutter sweep slitting caught by this loom.
Fig. 3 be this loom catch latitude cutter sweep correction ring face structural representation.
Fig. 4 is the side-looking structural representation that latitude cutter sweep slitting caught by this loom.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
Consult Fig. 1 and Fig. 3, in the present embodiment, this loom is caught latitude cutter sweep and is comprised shear component, conductive warp yarns jet and be arranged on the correction ring 200 of catching latitude end, weft yarn 10 movement locus is by described correction ring 200, described correction ring 200 is made up of the arc bar of two axis coincidings, described arc bar is symmetrical along axle center, article two, form two gaps between described arc bar end face, the inner side of described arc bar is provided with conductive layer 210, described shear component is made up of the slitting 100 of two tip oscillation respectively through two described gaps, described slitting 100 distributes along the axisymmetrical of described arc bar, described slitting 100 is separated by reciprocally swinging and closes on weft yarn movement locus, when weft yarn 10 is by described correction ring 200, described slitting 100 is positioned at described gap, described slitting 100 is closed behind described gap, the tip of described slitting 100 is provided with conducting strip 110, described conductive layer 210, conducting strip 110 and conductive warp yarns jet are all electrically connected with a pole of an electrostatic generator.
Consult Fig. 4, when described slitting 100 is positioned at described gap, described conducting strip 110 parallels with weft yarn transmission locus, the described conducting strip 110 on two described slittings 100 is parallel to each other, the electric-field intensity of generation is uniformly distributed.
Consult Fig. 2, the width at described slitting 100 tip is more than 1.1 times of weft yarn 10 diameter, makes the enough wide error that can overcome weft yarn 10 and also exist after electric field correction of slitting 100.
The operation principle of latitude cutter sweep caught by above-mentioned loom:
Consult Fig. 1, Fig. 2 and Fig. 3, weft yarn 10 is static electrification lotus after described conductive warp yarns jet, when weft yarn 10 enters described correction ring 200, described arc bar and the conducting strip 110 on slitting 100 are with electric charge identical on yarn 10 and be periphery around yarn 10, yarn 10 doing of repelling of like charges electrostatic force with under correct to described correction ring 200 axe movement, described slitting 100 swings, the tip of slitting 100 is near catching weft yarn 10, consult Fig. 2, when slitting 100 contacts completely, weft yarn 10 is truncated.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included in protection scope of the present invention.
