Abstract

The invention discloses a knitting machine needle selector driven by piezoelectric ceramic sheet. Said needle selector is formed from machine frame, piezoelectric ceramic driving sheet, positioning plate, needle-selecting blade, latch and cover plate. Said invention adopts the symmetric and parallel type piezoelectric ceramic sheets, and provides its concrete structure, and its working principle and its operation steps.

Description

technical field [0001] The invention relates to a needle selector for a knitting machine, in particular to an improved needle selector for a knitting machine driven by piezoelectric ceramic double diaphragms. Background technique [0002] At present, the known piezoelectric ceramic needle selector is designed using the bending driving principle of piezoelectric ceramic symmetrical double diaphragms, and is composed of a frame, a piezoelectric ceramic driving piece, a needle selection knife and a connecting device. However, the piezoelectric ceramic drive piece of the general piezoelectric ceramic needle selector is long, the fixing method and the transmission connection method are complex, the electromechanical conversion efficiency is low, and the needle selector is large in size. Contents of the invention [0003] In order to make up for the above-mentioned shortcomings, the present invention provides an improved needle selector for knitting machines with simple and comp...
