Problems solved by technology

However, the service life of Jacquard is inversely proportional to the driving voltage, and the increase of driving voltage will lead to a sharp decrease in the service life of Jacquard.
There is a contradiction between ensuring the operational reliability and service life of Jacquard, and it is impossible to have both

Abstract

The invention discloses a dual power supply and bidirectional drive circuit used in a piezoelectric ceramics jacquard comb. The drive circuit includes a power supply VCC1, a power supply VCC2, a piezoelectric ceramics wafer C1, a piezoelectric ceramics wafer C2, a control switch circuit S1 and a control switch circuit S2. According to the invention, the power supply VCC2 is configured to be in cooperation with the power supply VCC1, and a group of low-electricity drive voltages are added, which, on one hand, offsets a positive drive voltage so as to reduce voltages at two ends of a jacquard, and on the other hand produces an opposite force in the same direction as a positive force. The two forces are added and as a result of which a swing force is increased and compatibility between jacquard property and service life is achieved. Therefore, the drive circuit can increase jacquard drive voltage, at the same time meet requirements for jacquard properties, effectively prolongs service life of the jacquard, and reduces client usage and production cost.

Description

technical field [0001] The invention relates to a driving circuit for a piezoelectric ceramic chip, in particular to a dual-power bidirectional driving circuit for piezoelectric ceramic jacquard combs. Background technique [0002] Jacquard warp knitting machine is the main machine for producing mesh decorative fabrics, and its products are mainly used for interior decoration and decorative women's underwear fabrics and lace accessories. Since its inception in 1884, the jacquard device of the jacquard warp knitting machine has developed from mechanical to electromagnetic and now piezoelectric. Piezoelectric Jacquard. [0003] Piezoelectric jacquard warp knitting machine or piezoelectric jacquard crochet machine is a kind of textile machine that uses piezoelectric jacquard combs to jacquard. Generally, a jacquard comb is formed by combining multiple piezoelectric ceramic jacquard needles. The two sides of each piezoelectric ceramic jacquard needle are respectively pasted wi...
