Description

Technical Field

[0001] The utility model relates to the technical field of knitting machines, in particular to a graded transmission device of a knitting machine. Background Art

[0002] A knitting machine is a machine used to weave knitted fabrics. It can produce a variety of knitted fabrics and knitted products, such as sweaters, gloves, etc. Knitting machines can be divided into different types, including flat knitting machines and flat needle machines, among which flat knitting machines are mainly used to produce plain knitted fabrics.

[0003] During the transmission process of the knitting machine, a graded transmission device is required to adjust the running speed of the machine body and set the appropriate speed according to work needs. Common graded transmission devices include sliding gear speed change, exchange gear speed change and clutch speed change. Because mechanical transmission needs to be re-matched when changing speed, if the speed is changed during operation, it may cause problems in the coordination between mechanical components, resulting in equipment failure.
