Description

A knitting machine thread cutting mechanism

technical field

The utility model relates to the technical field of knitting machines, in particular to a thread cutting mechanism of a knitting machine.

Background technique

Knitting Machine: A machine that knits "knitted fabrics". In 1589, the English priest William Lee invented the first hand knitting machine. In the 1870s, with the invention of the electric motor, the hand knitting machine was replaced by the high-speed electric knitting machine. Knitting refers to the use of knitting needles to form loops of various raw materials and varieties of yarn, and then connect them into knitted fabrics through strings. process. The knitted material is soft and has good wrinkle resistance and breathability, as well as greater extensibility and elasticity, and is comfortable to wear. In addition to being used for consumption and decoration, knitted products can also be used in the fields of industry and agriculture, as well as medical care and national defense. Knitting is divided into two categories: manual knitting and machine knitting. Hand knitting uses stick needles, which has a long history, exquisite skills, and flexible flower shapes, and has been widely spread and developed among the people.

At present, the existing thread trimming mechanisms of knitting machines generally use scissors-type thread trimmers for thread trimming.
