Two-position control apparatus for superimposed cylinder stocking knitter shuttle

Abstract

A two-position control device of double-cylinder hosiery machine comprises a fixing block, a piston base, a shuttle guide plate, a shuttle fixing plate, and an action plate, a shuttle, cylinders and a torsional spring fixed on the shuttle guide plate, wherein a full-position piston is arranged on the piston base; the upper end of the full-position piston is matched with the action plate; a semi-position piston is also arranged on the piston base; the upper end of the semi-position piston is matched with the action plate; and the travel of the semi-position piston is smaller than the travel of the full-position piston. The two-position control device has the advantages that the occurrence of slip stitch of spandex thread is obviated in the initial period of knitting a main yarn and the spandex thread; and the hosiery can be knitted continuously by using one main yarn shuttle without frequently replacing the main yarn shuttle while knitting the leg, the heel, the bottom and the head of hosiery, thus obviating poor conditions such as the occurrence of joints, slip stitch, and omission of spandex. After changed, the device of the invention has no significant change in the general structure as compared with the original structure, the manufacture cost is not increased remarkably, and the device has convenient maintenance and extremely low maintenance cost.

Description

technical field [0001] The invention relates to a part of a double-cylinder hosiery machine, in particular to a two-position control device for a shuttle of a double-cylinder hosiery machine. Background technique [0002] The HDL fully computerized double-cylinder hosiery machine produced by Korean brother company, and many other similar fully computerized double-needle cylinder hosiery machines at home and abroad, have only one gear for the electric control shuttle. , and the toe of the sock must be constantly replaced, which is likely to cause bad phenomena such as too many joints, missing stitches, and spandex leakage. The role of the half position without the transitional role, it is easy to produce the phenomenon of spandex leakage, which affects the quality of socks. Contents of the invention [0003] The present invention aims at the problems existing in the prior art, and its purpose is to provide a two-position control device for double-needle hosiery machine shu...
