Embodiment Construction

[0013] The invention discloses an improved latch needle, which includes a needle head, a needle neck, a needle body and a needle tail. The needle head includes a needle hook 1 and a needle latch 2. There is a small hole, the thin end of the first spring piece 3 is inserted in the small hole, and the other end is fixedly arranged on the needle body. On the b surface of the latch needle, a long strip-shaped groove 4 is milled in the middle of the needle body. A second spring piece 5 is placed in the groove 4 , one end of the second spring piece 5 facing the needle tail is inserted into the groove 4 , and the other end is fixedly arranged in the groove 4 .

[0014] One end of the first spring piece 3 fixedly arranged on the needle body and one end of the second spring piece 5 fixedly arranged in the groove are both arranged on the needle body by welding.

[0015] The middle parts of the first spring piece 3 and the second spring piece 5 both protrude, and both are higher than the...

Abstract

The invention discloses an improved latch needle which comprises a needle head, a needle neck, a needle body and a needle butt, wherein the needle head includes a beard and a latch. On an a side of the latch needle, a pore is arranged on the needle neck in a direction in which the needle neck faces the needle head, the small end of a first spring piece is inserted in the pore, and the other end of the first spring piece is fixed on the needle body. On a b side of the latch needle, an elongated groove is milled in the middle of the needle body, a second spring piece is disposed in the groove, one end of the second spring piece, which faces the needle butt, is inserted in the groove, and the other end of the second spring piece is fixed in the groove. According to the improved latch needle, contact areas between the spring pieces and needle grooves are enlarged, the latch needle is enabled to work in the needle grooves more stably by means of tension of the spring pieces, knitting accuracy is guaranteed, durability of the spring pieces is improved, and the needle butt of the latch needle is not needed to be processed to be arc-shaped any more.

Description

technical field [0001] The invention relates to the technical field of flat knitting machines, in particular to an improved latch needle. Background technique [0002] At present, the needle tail of the traditional latch needle is curved in an arc shape, and the needle tail is in contact with one side of the needle groove (insert piece) of the loom. The purpose is to avoid the inertia effect of the latch needle in the needle groove, but such a latch needle The stability in the work is not ideal, and the knitting accuracy cannot be guaranteed; the spring leaf of the traditional latch needle is processed together with the needle body by stamping and riveting. In order to facilitate the stamping of the spring leaf, the local hardness of the needle body is reduced. , In the traditional process, the stamping of the spring leaf cannot effectively control the connection firmness of the spring leaf and the needle body. Contents of the invention [0003] The problem to be solved b...
