Seaming device for fabrics with different needle pitches

Abstract

The invention discloses a stitching device of different needle distances of fabrics. The stitching device comprises a main motor, a rotating speed ratio conversion device, a loop transfer device, a collar shifting needle rake and a disk stitching machine; the rotating speed ratio conversion device comprises a main transmission wheel which sleeves a motor shaft of the main motor; one end of a first conveyor belt and one end of a second conveyor belt sleeve the main transmission wheel; the other end of the first conveyor belt sleeves a needle rake movable device; the other end of the second conveyor belt sleeves a disk movable device; the needle rake movable device comprises a third gear which is used for driving the collar shifting needle rake; the disk movable device is fixed on a disk of the disk stitching machine; the disk movable device comprises a fourth gear which is used for driving the disk to rotate; the loop transfer device is arranged on a base of the needle rake movable device. According to the stitching device of the different needle distances of fabrics, the manpower required by the manual coil sleeving in the prior art is omitted, the wrong stitch and the missed stitch produced in the process of abutting joint of the fabrics are avoided, and accordingly the stitching efficiency and the stitching quality of the fabrics are greatly increased.

Description

technical field [0001] The invention belongs to the technical field of knitting machinery, in particular to a sewing device for fabrics with different needle pitches. Background technique [0002] In the prior art, the fabric woven by the flat knitting machine can be kept on the neck transfer needle rake, and the fabric on multiple neck transfer needle rakes can be transferred to the same needle rake through a professional device, and then the needle rake with the fabric can be directly transferred to the same needle rake. Put it on a special sewing machine and sew it directly. But this method is only applicable to the needle pitches on the neck shifting rakes with fabrics are all the same, and the needles can be directly docked. When the needle pitches of the fabrics to be stitched are different, the neck rake cannot be docked, so the fabric can only be taken off, and two pieces of fabrics with different needle pitches are placed on the disc by hand for sewing. This metho...

Problems solved by technology

This method is not only a waste of manpower and low work efficiency, but also prone to wrong stitches and missing stitches, which greatly affects the quality and aesthetics of the fabric.
