Abstract

The invention relates to a prestress jacquard guide needle. The prestress jacquard guide needle comprises a piezoelectric vibrator, a guide needle head, a lower positioning block and an upper positioning block, wherein the piezoelectric vibrator comprises an elastic base plate and four piezoelectric ceramics, the elastic base plate comprises a middle cantilever, a side cantilever and a cantilever connecting area, the piezoelectric ceramics are respectively distributed on the upper surface and the lower surface of the side cantilever, the guide needle head is bonded to one side of the cantilever connecting area, the piezoelectric vibrator is fixed by virtue of the upper positioning block and the lower positioning block, the piezoelectric vibrator has reciprocating curved deformation under the effect of the alternating-current voltage, the piezoelectric vibrator drives the guide needle head to move, the deviation of the entire guide needle head is realized, the needle head drives a yarn to move, the prestress jacquard guide needle is greater in deviation amount and greater in output force, and the service life of the jacquard guide needle can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of piezoelectric ceramic warp knitting machines, in particular to a prestressed jacquard guide needle. Background technique [0002] The jacquard guide needle is used in the jacquard warp knitting machine and is the key component to realize the jacquard function. The deflection of the guide needle is realized by using the inverse piezoelectric effect. The polarized piezoelectric ceramic chip will produce contraction and extension deformation when applied with voltage, so that the yarn guide needle will 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 force of the traditional yarn guide needle ar...
