Knitting mechanism for computerized flat knitting machine and method

Abstract

The invention relates to a knitting mechanism for a computerized flat knitting machine and method. The knitting mechanism comprises a triangular bottom plate and a knitting assembly, wherein at leastone knitting unit is arranged on the triangular bottom plate; the knitting units and the knitting assembly are mutually matched for knitting; the knitting unit comprises a left upper protection plate,a right upper protection plate, a protruding plate, a stitch transfer cam, a left stitch cam, a right stitch cam, a left back stitch cam, a right back stitch cam, a knitting cam, a disc plate, a leftactuator, a right actuator, a left connecting needle pressing sheet, a tucking pressing sheet, a right connecting needle pressing sheet, a non-weaving pressing sheet, a guide cam and actuating cams,wherein two actuating cams are arranged as a pair; and the left connecting needle pressing sheet, the tucking pressing sheet and the right connecting needle pressing sheet are located between the two.The actuating cam structure is simply designed with three actuating positions; in comparison with the existing bottom plate, the bottom plate structure is more simplified, the weight is lighter, functions are still the same, the knitting efficiency is improved, five basic actions of knitting, tucking, stitch transfer, needle connecting and non weaving can be carried out, and a specific needle knitting method is given.

Description

technical field [0001] The invention relates to a computerized flat knitting machine, in particular to a knitting mechanism and method for a computerized flat knitting machine. Background technique [0002] The bottom plate structure on the head of the computerized flat knitting machine and the knitting needles on the needle bed cooperate 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 ...

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
