Knitting mechanism for flat knitting machine and method

Abstract

The invention relates to a knitting mechanism for a flat knitting machine and a method. The knitting mechanism comprises a triangular bottom plate and a knitting needle assembly. At least one knittingunit is arranged on the triangular bottom plate, the knitting unit and the knitting assembly cooperate to carry out knitting, the knitting unit comprises an upper left protection plate, a swing cam,a needle turnover cam, an upper right protection plate, a left stitch cam, a right stitch cam, a knitting cam, a disc assembly, a guide assembly corner, a non-woven pressing sheet and a needle selecting cam. A needle groove is formed in a needle plate body, combined knitting needles are arranged in the needle groove, and the combined knitting needles comprise a retreating needle, a long stitch, ashort stitch and a needle selecting stitch. The needle selecting triangular structure design is simple, processing is easy, and the needle selecting position is accurate. Compared with an existing bottom plate device, the bottom plate structure is more simplified, the weight is reduced, the long stitch is only provided with a needling butt, the structure is simple, five basic actions of knitting,ring gathering and needle turnover and non-weaving can be carried out, and a specific needling knitting method is provided.

Description

technical field [0001] The invention relates to a computerized flat knitting machine, in particular to a knitting mechanism and method for a flat knitting machine. Background technique [0002] The bottom plate structure on the head of the computerized flat knitting machine enables the knitting needles to complete the five basic actions of knitting, tucking, transfer, stitching and non-knitting. Needle selection is required before knitting, so as to implement different knitting, tuck or non-knitting states. The usual way of needle selection and movement is realized by the movement of various triangles installed on the needle selection master board. For example, the application announcement The Chinese patent with the number CN108085856A and the application publication date of 2018.05.09: double-system computerized flat knitting machine base plate, in the flat knitting machine base plate device, the needle selection is realized jointly by the lower guard, the needle push cam ...

Needle selection is required before knitting, so as to implement different knitting, tuck or non-knitting states. The usual way of needle selection and movement is realized by the movement of various triangles installed on the needle selection master board. For example, the application announcement The Chinese patent with the number CN108085856A and the application publication date of 2018.05.09: double-system computerized flat knitting machine base plate, in the flat knitting machine base plate device, the needle selection is realized jointly by the lower guard, the needle push cam and the needle selector. It is a haunted design, the back of the flat knitting machine base plate is equipped with a control mechanism for controlling the push pin cam, and the flat knitting machine base plate is also equipped with a long guard hill that cooperates with the lower guard hill, resulting in a complex structure of the entire flat knitting machine base plate and zero triangle. The number of parts is large, the installation is inconvenient, and mechanical failures such as firing pins are prone to occur, which affects the knitting efficiency

[0003] The Chinese patent also discloses an invention patent with the application publication number 106222866A and the application publication date of 2016.12.14: a double-mesh needle pressing panel. The needle pressing module in this application includes the knitting needle selection pressing sheet, the needle selection triangle and the pressing needle In this application, the cam device on the panel is greatly simplified, the structure is simple, and the number of cam parts is small, but the structure design of the needle selection cam is complicated, and the processing is time-consuming. The needle is prone to defects such as hitting the needle
