Knitting device and method of computerized flat knitting machine

Abstract

The invention discloses a knitting device and method of a computerized flat knitting machine. The knitting device comprises a triangular bottom plate and a knitting assembly. At least one knitting unit is arranged on the triangular bottom plate. The knitting units and the knitting assembly are matched for knitting. Each knitting unit comprises an upper left protection hill, a swing triangle, a needle turning triangle, an upper right protection hill, a left needle returning triangle, a right needle returning triangle, a left indexing triangle, a right indexing triangle, a left two-section indexing triangle, a right two-section indexing triangle, a knitting triangle, a disk hill, a guide triangle, a non-knitting press piece and a needle selecting triangle. The knitting assembly comprises a needle plate body. A needle groove is formed in the needle plate body and internally provided with a knitting needle assembly. The knitting needle assembly comprises a nest needle, a long needle pin, ashort needle pin and a needle selecting pin. The needle selecting triangle is simple in structural design and easy to machine, and three needle selecting positions of hanging, knitting and non-knitting are obtained; the bottom plate is more simplified in structure and relieved in weight; by means of the dual-layer indexing structure, seven knitting actions of knitting, hanging, needle turning, needle collecting, non-knitting, tight hanging and tight knitting can be conducted.

Description

technical field [0001] The invention relates to a computerized flat knitting machine, in particular to a knitting device and method for a computerized 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...

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
