A high-efficiency and automatic molding method for large circular knitting machine needle cylinders

Abstract

The invention discloses a high-efficiency and automatic molding method for a large circular knitting machine needle cylinder, which comprises the following steps: processing an inner needle cylinder blank and a plurality of outer needle cylinder blanks that can be fixed and covered on the outer side wall of the inner needle cylinder blank; A threaded hole is processed on the inner wall of the inner syringe blank, and a connecting hole corresponding to the threaded hole is processed in the inner syringe blank; a plurality of outer syringe blanks are spliced ​​into a ring-shaped outer syringe blank body, and the outer syringe blank body is processed fixed; the outer wall of the main body of the outer syringe blank is processed until the outer wall of the main body of the outer syringe blank is covered with needle grooves; the main body of the processed outer syringe blank is fixedly connected with the inner needle blank; When the groove is damaged, the outer syringe blank can be replaced according to the damaged area, without the need to scrap the entire syringe, which is more environmentally friendly and reliable; and by processing multiple outer syringe blanks, the fault tolerance rate of the overall syringe processing is improved, and it will not be caused by processing A mistake caused the entire syringe to be scrapped.

Description

technical field [0001] The invention relates to the field of knitting machinery, in particular to a high-efficiency and automatic molding method for a needle cylinder of a large circular knitting machine. Background technique [0002] Large circular knitting machines are widely used in the textile industry. Large circular knitting machines have many knitting systems, high speed, high output, flower shape changes, good fabric quality, less processes, and strong product adaptability, so they develop rapidly. In large circular knitting machines, The needle cylinder is very important. The function of the needle cylinder is mainly to fix the knitting needles of the large circular machine and drive the knitting needles to work; most of the existing needle cylinder processing is to cut the needle groove on the outer wall of the needle cylinder blank at one time, and cut the needle groove Sometimes due to the shaking of the cutting device or the unstable fixing of the needle cylinde...

[0002] Large circular knitting machines are widely used in the textile industry. Large circular knitting machines have many knitting systems, high speed, high output, flower shape changes, good fabric quality, less processes, and strong product adaptability, so they develop rapidly. In large circular knitting machines, The needle cylinder is very important. The function of the needle cylinder is mainly to fix the knitting needles of the large circular machine and drive the knitting needles to work; most of the existing needle cylinder processing is to cut the needle groove on the outer wall of the needle cylinder blank at one time, and cut the needle groove Sometimes due to the shaking of the cutting device or the unstable fixing of the needle cylinder, the cutting of individual needle grooves is incomplete, resulting in the scrapping of the entire needle cylinder, which is a waste of raw materials; the processing of needle cylinders through this processing technology has a very high error tolerance rate. the small
