Abstract

The invention discloses a novel warp knitting machine piezoelectric jacquard element which comprises two piezoelectric ceramic chips and a substrate. Two piezoelectric ceramic chips are adhered on both sides of the substrate. The substrate comprises a fiber layer, wherein both sides of the fiber layer are coated by copper thin films. The fiber layer is composed of one or more unidirectional fiber layers and one or more warp and weft fiber layers. Due to the fact that the fiber layer is composed of one or more unidirectional fiber layers and one or more warp and weft fiber layers, the problem that when monolayer and unidirectional fiber cloth is pressed, fiber flows and bends with watering can be effectively avoided. The flatness of the surface of a fiberboard is improved. The fiberboard is not easy to crack when bent and used.

Description

[0001] technical field [0002] The invention relates to the technical field of piezoelectric ceramic warp knitting machines, in particular to a novel piezoelectric jacquard element for warp knitting machines. Background technique [0003] 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...
