An anti-snag groove needle swing lever assembly

Abstract

The invention discloses an anti-snaking groove needle swing rod assembly, which comprises a groove needle and a swing rod. The groove needle has a longitudinal groove, and the swing rod main body is accommodated in the groove, and U-shaped Opening; the head of the upper end of the swing rod is in the shape of a "7" hook, and the lower end of the swing rod protrudes out of the longitudinal groove of the groove needle. The upper ends of the groove walls on both sides are provided with stepped surfaces, bounded by the stepped surfaces, the groove walls on both sides above the stepped surface are closely fitted, the groove walls on both sides below the stepped surface form longitudinal grooves, and the stepped surfaces of the groove walls on both sides form The top end of the longitudinal groove; the stepped surfaces on both sides are higher than the head of the swing rod. In the present invention, by changing the processing technology of the grooved needle, a stepped surface is processed on the head of the grooved needle, and the groove wall above the stepped surface is closely fitted, so that the head of the grooved needle is flattened and the gap is closed, thereby reducing the problem of yarn snagging of the grooved needle .

Description

technical field [0001] The invention belongs to the technical field of flat knitting knitting machines, and particularly relates to an anti-yarn groove needle swing rod assembly. Background technique [0002] When the computerized flat knitting machine is starting from the bottom, the starting needle used is the groove needle and the swing rod assembly includes a groove needle and a swing rod. When the groove needle swing rod assembly moves upward, the swing rod swings left and right to hook the yarn at the head, and then move to the side. Downward movement until the head yarn is pulled out of the roller and unlooped. [0003] The applicant has once applied for a patent for an opening needle, the patent number is 2008100604152, a sewing needle for a flat knitting machine, including a groove needle and a swing bar, the groove needle has a longitudinal groove, and the swing bar main body is accommodated in the groove, such as figure 1 As shown, the groove needle 5 is a rectan...

AI Technical Summary

Problems solved by technology

The slot needle and the swing bar are combined by rivets, and the swing bar swings left and right and cooperates with the U-shaped opening of the slot needle slot needle to carry out yarn hanging and yarn removal. However, since the original slot needle 5 is composed of two metal composites, the slot needle longitudinal The cross-section of the head is an inverted V-shaped structure 52, two pieces of metal are combined at an acute angle, and there is a gap between the two pieces of metal, that is, there is a gap 53 at the acute angle where the two pieces of metal form an inverted V shape, such as figure 2 shown

Therefore, when the swing lever releases the yarn, the gap in the middle of the grooved needle head can easily catch the yarn on the machine head, resulting in the situation that the grooved needle cannot be hooked or taken off when hooking the yarn.
