Abstract

The invention relates to a prestress piezoelectric vibrator jacquard guide needle. The prestress piezoelectric vibrator jacquard guide needle comprises a substrate, a piezoelectric vibrator, a pre-tightening spring and a needle head, wherein a spring installation ring and two vibrator installation grooves are arranged on one side surface of the substrate; the piezoelectric vibrator consists of a U-shaped elastic base plate and piezoelectric sheet materials, the U-shaped elastic base plate comprises two cantilevers and a cantilever connecting area; a spring installation hole is formed in the cantilever connecting area; the tail ends of the two cantilevers are respectively arranged in two vibrator installation grooves in the substrate; the piezoelectric sheet materials are respectively attached to the upper surface and the lower surface of the two cantilevers; one end of the pre-tightening spring is connected with the spring installation ring, and the other end of the pre-tightening is connected with the spring installation hole; the needle head is arranged on the tail end of the piezoelectric vibrator cantilever connecting area. The prestress piezoelectric vibrator jacquard guide needle is widely applied to the field of a piezoelectric warp knitting machine. Compared with the traditional piezoelectric vibrator jacquard guide needle, the vibration amplitude is greater, and the output force is stronger.

Description

technical field [0001] The invention belongs to the technical field of piezoelectric ceramic warp knitting machines, and in particular relates to a prestressed piezoelectric vibrator jacquard yarn guide needle. Background technique [0002] The jacquard guide needle is used in the jacquard warp knitting machine and is the key part to realize the jacquard function. The deflection of the guide needle is realized by using the inverse piezoelectric effect. The polarized piezoelectric ceramic chip is applied with an alternating voltage to produce contraction and expansion deformation, which makes the yarn guide needle deviate to the left or to the right. The piezoelectric vibrator in the existing jacquard guide needle is formed by bonding a piece of ordinary elastic substrate with piezoelectric ceramics. The traditional jacquard guide needle formed by bonding such an ordinary piezoelectric vibrator to the guide needle , under the same voltage, the offset displacement and output ...
