Abstract

The invention discloses a guide bar moving mechanism of a warp knitting machine. The guide bar moving mechanism comprises a transmission main shaft and a guide bar swinging mechanism, wherein the transmission main shaft is installed inside a warp knitting machine oil tank in a rotating mode. The guide bar swinging mechanism comprises a guide bar base, a first connecting rod transmission mechanism and a swinging main shaft installed on a warp knitting machine frame in a rotating mode. The guide bar base is fixedly installed on the swinging main shaft. A plurality of guide bars are installed on the guide bar base. At least one guide bar is a jacquard guide bar. During knitting, the transmission main shaft drives the swinging main shaft through the first connecting rod transmission mechanism to swing, and the swinging main shaft drives the guide bar base and the guide bars on the guide bar base to swing at the same time when swinging. The guide bar moving mechanism further comprises a jacquard guide bar vertical-moving mechanism which is driven by the transmission main shaft through a second connecting rod transmission mechanism so as to enable the jacquard guide bar to swing and conduct vertical linear motion at the same time. According to the guide bar moving mechanism, it is ensured that jacquard guide bar yarn laying is accurate and reliable, the missed stitch accident is avoided, and the fabric quality is improved.
