Abstract
A patterning finger tricot machine, the needle being integrated with the intermediate by dielectric made of electric materials, and then fixed onto the guide bar. The dielectric has piezoelectric coatings on both sides, which consist of interior electrode, piezoelectric coating covered by exterior electrode. The exterior electrode binds one control circuit which produces electron-positron pair to affect exterior electrode. The structure of this instrument is simple and the cost is low.
Description
Technical field
The present invention relates to field of textile machinery, especially for the warp knitting machine that has a sley bar at least, its sley point nationality helps jacquard weave control can be offset a needle gage at least.
Background technology
Traditional warp knitting machine adopts mechanical jacquard method, its complex structure, and it is big to take up room, and the machine driving during work is many, and the conversion difficulty of decorative pattern, and safety coefficient is also not high.Chinese patent ZL94117618.5 discloses a kind of warp knitting machine, its sley point by one by at least one flexural piezoelectric transducers effect flexible support strip in the middle of connect and to be fixed on the sley bar, support strip is made by electrically insulating material, and an effectively coating forming of layer and outer electrode and have a control circuit can be selectively to provide to internal electrode to control voltage and with outer electrode ground connection of the piezoelectricity that covered by internal electrode is provided on one side at least.The technical scheme of this invention can reach the effect of sley point skew, but its electrode constitutes, the circuit structure complexity, and cost is higher.
Summary of the invention
The purpose of this invention is to provide a kind of jacquard weave feed carrier that is used for simple in structure, the warp knitting machine that safety coefficient is high on the warp knitting machine.
The realization of above-mentioned purpose must be on the warp knitting machine that has a sley bar at least, and its sley point can be realized the skew of a needle gage at least by external control, and sley point fuses by insulating materials and intermediate, and then is fixed on the sley bar.Wherein, each intermediate is made by conductive material, on its two sides, all be loaded with the piezoelectricity coating, this coating is made up of internal electrode, piezoelectric deforming layer and the outer electrode that covers on the piezoelectricity coating, outer electrode connects a control circuit, and this control circuit produces positive negative potential and acts on outer electrode.
Internal electrode is for directly coating the intermediate of conductive glue, and is simple in structure, easy to operate.
In addition, exposed nonisulated section of being used for wiring adopts insulating materials on the outer electrode, and be as the resin mass of palisade that all different outer electrodes are isolated one by one, thereby guarantee the mutually insulated between each piezoelectric deforming device.
Compare with traditional mechanical jacquard weave or the existing warp knitting machine of piezoelectric deforming device sley point that adopts, advantage of the present invention is not only effectively to have saved mechanical space, reduced machine driving, the conversion decorative pattern is very convenient, and external control voltage adopts 50 volts, can not damage human body, security is good, in addition, electrode constitutes in the piezoelectric deforming device of the present invention, the control circuit structure is also very simple, and relative cost is lower.

Provide preferred forms of the present invention below in conjunction with description of drawings.
Preferred forms
Intermediate 3 is by conduction and have certain flexible material such as silicon steel sheet to make, in its coated on both sides conductive material such as conductive glue, so form an internal electrode 4 and 5 respectively on the two sides of intermediate 3, because internal electrode 4,5 and intermediate 3 all are conductors, so two internal electrodes 4 conduct mutually with 5.
Form two piezoelectric deforming devices 12 (comprising 3,4,6,8,10) and 13 (comprising 3,5,7,9,11) thus altogether.
As Fig. 2, adopted a control circuit 16 that positive negative potential can be provided, its two outputs 18 and 19 provide one positive one negative two kinds of current potentials, the terminals on the external electrode (20,21) respectively, behind lead M, N short circuit, be connected with positive and negative current potential selectively by switch 24 again.Internal electrode is always zero potential.Thereby form two loops with two outer electrodes.
Position shown in Fig. 2, piezoelectric deforming device 12,13 bends to the direction of arrow shown in the figure simultaneously, because controlled by positive potential on the terminals 20,21, so intermediate 3 takes place also as direction of arrow bending among the figure, sley point 1 is also done to be offset accordingly as the direction of arrow thereupon, and the switching by switch 24 can make intermediate 3 take place and direction of arrow opposite curvature.
Among Fig. 3, by the fixture of being made by insulating materials 14 intermediate 3 is fixed on the sley bar 15, because whole sley bar 15 ground connection, intermediate 3 contacts fully with sley bar 15, has therefore guaranteed intermediate 3 ground connection all the time.
Among Fig. 4, pilot M1~Mn or N1~Nn under the terminals on each intermediate 3 are drawn separately control the independent offset that just can realize each sley point 1 by external circuit, and the extreme position of sley point 1 skew is determined by the limited block on the sley bar 23.
