Description

Technical Field

[0001] The utility model relates to the technical field of circular knitting machine needle cylinder machines, in particular to a needle cylinder structure of a double-sided circular knitting machine. Background Art

[0002] Circular knitting machine, scientific name is circular weft knitting machine (or circular weft knitting machine). Circular knitting machine has many loop forming systems (called yarn feeding route or loop forming route in enterprises, referred to as route), high speed, high output, fast pattern change, good fabric quality, few processes and strong product adaptability, so it has developed rapidly. The outer surface of the existing double-sided circular knitting machine needle cylinder mechanism is constructed with multiple needle grooves to place the knitting needles. When the knitting needles slide in the needle grooves, lubricating oil is required to avoid excessive friction. However, the lubricating oil is easily contaminated with lint on the yarn and dust in the air. After the dust accumulates, the knitting needles will be stuck by debris, affecting the operation of the equipment. The needle grooves need to be cleaned frequently. The existing cleaning method is generally to manually pick out the knitting needles in the needle grooves one by one, and then clean the needle grooves. The operation not only consumes a lot of manpower, but also consumes too much time, which seriously affects the production efficiency of the fabric.

[0003] This case was created to solve the above problems. Utility Model Content
