Novel multi-station jacquard needle control device of knitting machinery

Abstract

The invention discloses a novel multi-station jacquard needle control device of knitting machinery. The novel multi-station jacquard needle control device of the knitting machinery comprises an upper steel ring, a lower steel ring, a lower pulling head, a needle cylinder, needle selectors and jacquard needles. The jacquard needles move back and forth axially in axial grooves of the outer wall of the needle cylinder, the upper steel ring is fixed onto the upper portion of the needle cylinder and is concentric with the needle cylinder, the lower steel ring is fixed onto the lower portion of the needle cylinder and is concentric with the needle cylinder, every three needle selectors forms a group, all the four groups of the needle selectors are evenly distributed and fixed on the periphery of the lower steel ring, a center circle formed by fixing holes for installing the needle selectors is concentric with the lower steel ring, and the jacquard needles are evenly distributed inside the axial grooves of the outer wall of the needle cylinder. The novel multi-station jacquard needle control device of the knitting machinery has the advantages that achieving the effect that the low pushing head is used for controlling the jacquard needles to perform radial extrapolation motion in multiple stations and abandoning old spring piece type jacquard weaving. Therefore, in a working state, the radial movement and the axial movement of the jacquard needles are more accurate, sensitive and reliable, and wrong needle, missed stitch and needle collision during selection of the jacquard needle can be avoided.

Description

technical field [0001] The invention relates to a novel multi-station jacquard needle control device of a knitting machine. Background technique [0002] The multi-station jacquard needle control device of the existing knitting machine adopts the shrapnel type jacquard needle to realize the radial outward elastic movement of the jacquard needle, and the jacquard needle in the needle selection device of the existing knitting machine performs radial outward elastic movement. At this time, the main power source comes from the rebound force of the jacquard needle back spring acting on the bottom of the needle cylinder groove, so as to realize the jacquard needle to maintain the external elastic state at different positions. When the jacquard needles in the jacquard needle control device of the existing knitting machine perform radial internal pressure movement, the power source comes from the force of the inner push of the needle selector blade and the reaction force of the inne...

AI Technical Summary

Problems solved by technology

[0003] 1. The shrapnel on the back of the jacquard needle is prone to mechanical fatigue and local plastic deformation, which makes the outer elastic force insufficient, resulting in the jacquard needle not popping up or the outer spring not in place, and the phenomenon of missed or wrong selection, resulting in increased output of defective products decline, which also limits the operating speed of the machine

[0004] 2. When the needle selector selects jacquard needles, the needle selector blade not only bears the centrifugal force thrown by the jacquard needle when it makes a circular motion, but also has the rebound force from the shrapnel on the back of the jacquard needle acting on the bottom of the cylinder groove, causing the needle selector blade to If the load is too heavy, the needle selector blades and jacquard needles are easy to wear, which will affect the service life and equipment stability of the needle selector blades and jacquard needles
