Description

Weft insertion knitting structure of computerized flat knitting machine

Technical Field

The utility model relates to a computerized flat knitting machine, in particular to a weft insertion knitting structure of the computerized flat knitting machine.

Background

The cam device on the flat knitting machine needle bed is like a group of plane cams, the stitches of the knitting needles can enter the grooves of the cams, the cams are moved to force the knitting needles to regularly move up and down in the grooves of the needle bed, and the yarns can be knitted into a knitted fabric through the actions of the needle hooks and the needle tongues. During the ascending process of the knitting needle, the coil gradually withdraws from the needle hook, the needle latch is opened, and the withdrawing needle latch is hung on the needle rod. During the descending process of the knitting needle, the needle hook hooks the newly laid yarn and draws and bends the newly laid yarn into a coil, meanwhile, the original coil is pulled out of the needle hook, the new coil passes through the old coil and is connected with the old coil in series, and a plurality of coil strings woven by a plurality of knitting needles are mutually connected to form a braided fabric

The flat knitting machine is provided with the sinker mechanism, and sinkers on the sinker mechanism press or block coils in the looping process of the flat knitting machine, so that the knitting function of the flat knitting machine is greatly increased, and the patterns of knitted fabrics are enriched. When some thin fabrics are knitted, the sinker presses the yarn into the opening of the needle plate in the knitting process, the knitting needle hooks the yarn for knitting, the range of pressing the yarn downwards by the needle plate is small when the thick fabrics are knitted at present, particularly when the thick yarns are filled, the yarn cannot be pressed once the sinker exceeds the radius, the knitting needle cannot hook the yarn, the yarn which floats above the knitting needle cannot be pressed back, the yarn participates in looping and turns out, the knitting action is unstable, and even the sinker cannot rotate any more, so that the needle path of the manufactured fabrics is uneven, and the production quality of the fabrics is seriously reduced. The reason for causing this kind of phenomenon is mainly that the sinker structure that installs on the faller at present moves single position, and then the protrusion distance is shorter, the line ball radius is less, and in addition, current sinker structure still has the inconsistent defect of stroke of pushing down, finally leads to unable vamp and the clothing of weaving thicker.
