Abstract
The invention discloses a needle-pressing mechanism for a warp-knitting machine. The needle-pressing mechanism comprises a transmission main shaft, a jacquard needle bed, a jacquard needle-pressing assembly, a push needle, a push need guide block and a bearded needle. The transmission main shaft drives the push needle to perform reciprocating motion by means of a push needle movement mechanism in order to open and close the bearded needle so that knitting in loops is finished. The push needle movement mechanism comprises an eccentric wheel, an eccentric sleeve connecting rod, a first connecting rod, a second connecting rod, a first triangular connecting rod, an oil tank output rod, a second triangular connecting rod, a third connecting rod, a push needle shaft and a guide seat. The left end of the second connecting rod is rotatably connected with the right upper end of the first triangular connecting rod. The left upper end of the first triangular connecting rod is rotatably connected with the lower end of the oil tank output rod. The upper end of the oil tank output rod is rotatably connected with the left upper end of the second triangular connecting rod. The push needle shaft is arranged along a horizontal direction.
