Middle-edge needle separating knife assembly for hosiery machine

Abstract

The invention discloses a middle-edge needle separating knife assembly for a hosiery machine. The needle separating knife assembly is composed of an upper needle separating knife and a lower needle separating knife by overlapping, wherein the right end of the lower needle separating knife main body of the lower needle separating knife is provided with a lower protrusion extending downward at a right angle, the right end of the upper needle separating knife main body of the upper needle separating knife is provided with an upper protrusion extending downward at a right angle, and the right inner side of the lower board 404 of the lower needle separating knife is provided with a first upper protrusion which is attached to the end surface of a push rod of a built-in cylinder core. In the invention, a middle-edge needle block knife has been improved and is divided into upper and lower needle separating knives stacked in a middle-edge seat, two cylinders are used to push and move, the upperneedle separating knife and the lower needle separating knife are reset by springs after the cylinder is depressurized and deflated, and the processes can be executed separately or jointly under thecommands of an operating system of the hosiery machine, which solves the problem of a single function that the original hosiery machine can only knit two-way elastic socks and the knife needs to withdraw when knitting the hosiery body, and also eliminates the problem of sock stitches and short stitches caused by the sock needles passing through the middle corners when the hosiery machine is running at a high speed.

Description

Technical field [0001] The invention relates to the technical field of sock knitting machines, in particular to a middle-edge minute needle knife assembly for sock knitting machines. Background technique [0002] Hosiery knitting machine is a knitting machine for producing socks. The main feature is that it can weave the heel and toe of the bag in both directions. The function of the knitting mechanism in the hosiery machine is to knit the yarn into a tubular stocking blank through the loop forming machine. The loop forming machine is composed of face needle, sinker, bottom corner piece and jacquard needle. The face needle moves up and down in the cylinder for knitting. The jacquard needle is set under the face needle to lift up the knitting needle when needed. [0003] The middle angular structure is an important part of the knitting mechanism, which provides a needle path for the needles raised to a certain height. The existing middle angular structure is usually like image 3 , ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a middle-angle minute knife assembly for hosiery machines. The minute knife assembly is composed of an upper minute knife and a lower minute knife. The right end is provided with a lower bump that extends downward at right angles. The upper bump one is combined, the present invention improves the needle-blocking knife in the middle corner, decomposes it into two needle cutters, the upper minute needle knife and the lower minute needle knife, and stacks them in the middle corner corner seat. After pressing and releasing the air, use the spring to reset the upper minute needle knife and the lower minute needle knife, both of which can be executed separately or jointly under the command of the operating system of the hosiery machine, which solves the problem of the single function of the original hosiery machine that can only weave two-way elastic socks. The problem that the knife needs to exit when knitting the sock body also eliminates the problem of missing needles and short threads of the sock machine caused by the inertia of the sock needle passing through the middle edge and downward when the sock machine is running at high speed
