Jacquard warp tension device for warp knitting machine

Abstract

A jacquard warp tensioning device for a warp knitting machine, comprising a pair of side panels (1) disposed on two sides of the machine casing, a warp beam (2) positioned at the upper portions of the side panels (1), a plurality of warp guide rods (3, 4, 5) disposed at positions lower than that of the warp beam (2) and a flat spring warp dividing device (16), wherein an upper tension balancing device (6) and a lower tension balancing device (11) are disposed between the warp beam (2) and the warp guide rods (3, 4, 5), the upper tension balancing device (6) comprising an upper rotating shaft (7) with two ends thereof disposed on the side panels (1), an upper servo motor (8) disposed at one end of the upper rotating shaft (7) and an upper tensioning rod (9) fixedly disposed on the upper rotating shaft (7) by means of a plurality of upper connecting rods (10), the lower tension balancing device (11) comprising a lower rotating shaft (12) with two ends thereof disposed on the side panels (1), a lower servo motor (13) disposed at one end of the lower rotating shaft (12) and a lower tensioning rod (14) fixedly disposed on the lower rotating shaft (12) by means of a plurality of lower connecting rods (15), the upper servo motor (8) and the lower servo motor (13) being connected with an industrial computer (17) through a servo driver (19), respectively. The jacquard warp tensioning device proactively controls warp tension and has a high level tension compensation, thereby making the yarns not prone to being broken and enabling smooth surfaces of woven fabrics.
