Description

Composite needle for spinning

Technical Field

The invention relates to the technical field of knitting machinery, in particular to a composite needle for spinning.

Background

The composite needle in the flat knitting machine with the publication number of CN109706615A in the prior art comprises a main needle and a needle sleeve sleeved on the main needle; the main needle is of an elongated shape, and the head part of the main needle is provided with a needle hook; the top end of the needle sleeve is provided with a vertex angle, one side of the needle sleeve facing the main needle is provided with a first fastener and a second fastener, the front side surface and the rear side surface of the main needle are provided with a first concave surface and a second concave surface in a segmented mode, and the first fastener and the second fastener are respectively buckled on the first concave surface and the second concave surface of the main needle; the side surface of the main needle facing the needle sleeve and the side surface of the needle sleeve facing the main needle are in mutual interference fit, so that when the needle sleeve moves, the vertex angle moves from the accommodating groove of the main needle to the needle hook of the closed main needle, the coil stripping resistance on the composite needle of the device is small, the loop stripping stroke is small, and the knitting speed is high; the knitting needles at the relative positions can be guided into the needle turning positions, the needle turning is reliable, and the action is simple and beneficial; the compound needle slides stably in the needle groove and the cloth cover is flat.
