Let-off device of warp knitting machine

Abstract

The invention relates to a textile manufacturing machine, in particular to a let-off device of a warp knitting machine. The let-off device comprises a creel let-off unit and a beam creel let-off unit. The creel let-off unit is located above the beam creel let-off unit. A top support of the beam creel let-off unit is supported on a mounting face through side supports. A beam is mounted on the side supports through a beam mounting component. A guide rod component is mounted on the top support. The creel let-off unit comprises at least one creel set mounted on the top support of the beam creel let-off unit. A pan head on the beam and a bobbin on the creel device are let off yarns to the warp knitting machine through the guide rod component. The let-off device has the advantages that the different requirements on let-off amount and tension are met, the whole warp knitting machine is compact in structure, space is fully utilized, plane area is reduced, let-off length is shortened, and yarn breakage caused by the fact that the excessive let-off length makes tension difficult to control is avoided effectively.

Description

technical field [0001] The invention relates to a textile machine, in particular to a let-off device of a warp knitting machine. Background technique [0002] The existing warp beam frame for double-needle bed warp knitting machine includes a plurality of pan head support seats fixedly connected to the lateral sides of the double needle bed warp knitting machine body, and the pan head set on the lateral sides. The supporting base is rotatably connected and arranged in parallel with a plurality of warp beams, a yarn guide rod assembly, a tension adjustment mechanism, and a yarn loop forming mechanism located at the lower part of the tension adjustment mechanism. The rod assembly includes a yarn guide rod base and a yarn guide rod installed thereon, and the tension adjustment mechanism includes a tension rod base, a tension rod and a tension sheet, and the tension adjustment mechanism is fixedly connected with the bed through the tension rod base; , the yarn passes through th...

Problems solved by technology

Such warp beam frames all use electronic let-off, so they cannot meet the different requirements for let-off amount and density when weaving different products, and the product types are limited, especially cannot meet the requirements for weaving double-sided forming jacquard plush fabrics.
