CN-224199588-U - Transfer needle and circular knitting machine

Abstract

The utility model relates to the technical field of knitting, in particular to a transfer needle and a circular knitting machine. The knitting needle comprises a knitting needle body and a ring expanding piece, wherein the ring expanding piece is provided with a first guide section, and the first guide section is obliquely arranged from the bottom surface of the ring expanding piece to the side surface facing the direction of a needle passing hole and extends along the length direction of the ring expanding piece, so that the needle passing hole forms a flaring structure at the position of the first guide section. Through setting up first guide section on expanding the circle piece, make and cross the pinhole and form flaring structure, improved the fault-tolerant rate that the needle got into and cross the pinhole of receiving the circle, ensured to move the circle success rate.

Description

Transfer needle and circular knitting machine Technical Field The utility model relates to the technical field of knitting, in particular to a transfer needle and a circular knitting machine. Background The knitting process of the loop transferring organization of the knitting machine is to expand the loops by advancing the loop transferring needle with the loop expanding piece, then advancing the corresponding loop receiving needle at the other side, leading the needle hook to pass through the hole formed by the loop expanding piece and the knitting needle body in the loop transferring needle, and simultaneously passing through the expanded loops, then retracting the loop transferring needle, and leading the loops needing to be transferred to the needle hook of the loop receiving needle. With the development of the market, customers demand cloth with finer and finer needle pitches, the needle thickness of the transfer needle is smaller and smaller, the gap formed by the loop expanding piece and the knitting needle body for the loop receiving needle to pass through is smaller, the loop can compress the loop expanding piece to enable the loop expanding piece and the hole formed by the knitting needle body to be smaller while the transfer needle jacks up and expands the loop, and the loop transferring difficulty and even the loop transferring failure are caused. In order to solve the problems, the design of the transfer needle is improved. Disclosure of utility model In order to overcome the defects in the prior art, the utility model provides a transfer needle and a circular knitting machine for improving the transfer fault tolerance. The transfer needle comprises a knitting needle body and a ring expanding piece, wherein the ring expanding piece is arranged on one side face of the knitting needle body, the rear end of the ring expanding piece is fixedly connected with the knitting needle body, the front end of the ring expanding piece is tightly attached to the side face of the knitting needle body, the middle section of the ring expanding piece is bent to enable a needle passing hole to be formed between the side face of the ring expanding piece and the side face of the knitting needle body, the ring expanding piece is provided with a first guide section, and the first guide section is obliquely arranged from the bottom face of the ring expanding piece to the side face facing the needle passing hole direction and extends along the length direction of the ring expanding piece, so that the needle passing hole forms a flaring structure at the position of the first guide section. Further, the needle body is provided with a second guide section which is obliquely arranged from the bottom surface of the needle body to the side surface facing the needle passing hole direction and extends along the length direction of the needle body, so that the needle passing hole forms a flaring structure at the position of the second guide section. Further, the second guide section length range covers the length range of the first guide section. Further, the included angle between the first guide section and the vertical surface is 15-35 degrees, and the included angle between the second guide section and the vertical surface is 15-35 degrees.
