Description

Letter gram device for flat knitting machine

Technical Field

The utility model relates to the technical field of computerized flat knitting machines, in particular to a signal gram device for a flat knitting machine.

Background

The sinker of the computerized flat knitting machine is arranged between two knitting needles and is controlled by a cam of a letter gram, so that the sinker swings back and forth and presses the fabric when closed, thereby facilitating the completion of knitting and needle turning actions, and the sinker is opened immediately before the completion of looping and needle joining.

The following problems exist with the current sigma delta:

when the traditional letter triangle acts on the mountain plate, the letter triangle can only move in one direction (such as transversely to the left and right or vertically upwards and downwards). Under the condition, due to the influence of the matching of the stitch inlet of the cam and the looping position and the singleness of the movement direction of the cam, when the machine is in the loop-off or stitch-turning position in normal knitting, the sinker can not completely play the role of assisting loop-off, and the loop can float up along with the knitting needle. Resulting in fabric blemishes such as floats and needle leaks. For some special flower-shaped products, because the signal gram triangle can only move horizontally and laterally or vertically and up and down independently, the signal gram triangle function can only be closed or the product can not be produced;

in the knitting process, when the knitting needle carries out multiple partial knitting or long-dashed line filling knitting, the coil or the long-dashed line on the knitting needle cannot be subjected to the traction force exerted by the traction mechanism on the flat knitting machine, the coil or the long-dashed line floats on the tooth mouth piece, when the sinker hook part is closed, the coil or the long-dashed line on the knitting needle cannot be effectively pressed, the coil moves upwards along with the knitting needle and cannot be separated from the needle latch of the knitting needle, and the coil cannot be retracted, so that the knitting needle cannot complete knitting, and the fabric quality is affected.
