Abstract
A drive circuit board controlling movement of piezoelectric jacquard weaving devices in a warp knitting machine comprises a golden-finger insertion interface, a data channel selecting module, a group-selecting addressing module, a control logic module, a high and low-voltage photoelectric isolation module, a serial-in-parallel-out module A, a jacquard drive output interface module A, a serial-in-parallel-out module B and a jacquard drive output interface module B. The golden-finger insertion interface transmits pattern type data, addresses, control and clock signals to the eight-path data channel selecting module. The 16-bit group-selecting addressing module and the control logic module finish addressing and controlling signal conditioning. Photoelectric isolation is further performed on the signals through the high and low-voltage photoelectric isolation module. Low-voltage serial-input deviating movement data of the piezoelectric jacquard weaving devices are converted into high-voltage parallel-output data through the serial-in-parallel-out modules. The high-voltage parallel-output data are then output to the piezoelectric jacquard weaving devices through the jacquard drive output interface modules. The drive circuit board controlling the movement of piezoelectric jacquard weaving devices in the warp knitting machine has the characteristics of high integration level, low power dissipation, reliability and durability.
