Abstract

The invention discloses a piezoelectric jacquard element of a warp knitting machine, which includes two piezoelectric ceramic wafers and a base sheet. The two piezoelectric ceramic wafers are bonded on both sides of the base sheet. The base sheet is composed of a fiber layer. Both sides are coated with copper films, and the fiber layer is composed of one or more unidirectional fiber layers and one or more layers of warp and weft fiber layers, using one or more layers of unidirectional fiber layers and one or more layers of warp and weft fibers. The layer composition design can effectively remove the influence of the fiber bending with the flow of glue during the pressing process of the single-layer unidirectional fiber cloth, improve the flatness of the surface layer of the fiber board, and make the fiber board less likely to crack during bending use.

Description

technical field [0001] The invention relates to the technical field of piezoelectric ceramic warp knitting machines, in particular to a piezoelectric jacquard element of a warp knitting machine. Background technique [0002] The warp knitting machine piezoelectric jacquard element is used to control the deflection of the jacquard guide needle on the warp knitting machine. It consists of two piezoelectric ceramic wafers separated by a substrate. The polarized piezoelectric ceramic chip will produce shrinkage and stretching deformation when applied with voltage. At the same time, in order to transmit the voltage, a copper-clad fiberboard with good elasticity and conductivity is used. Through the switching of the circuit switches on both sides, voltage is applied alternately on both sides of the piezoelectric jacquard element, and the piezoelectric ceramic is deformed, so that the yarn guide needle deviates to the left or to the right. Because the piezoelectric ceramic acts l...
