Round machine for knitting waistbands of underclothes

Abstract

The invention provides a round machine for knitting waistbands of underclothes, and belongs to the field of textile machinery. The round machine for knitting the waistbands of the underclothes comprises a rack, a weaving mechanism, a transmission mechanism, a yarn feeding mechanism, a blanking mechanism and a control system. The yarn feeding mechanism and the weaving mechanism are arranged above the rack and are sequentially arranged from top to bottom. The transmission mechanism drives the weaving mechanism, the yarn feeding mechanism and the blanking mechanism to act. The control system is connected with the mechanisms and controls the mechanisms to act. The weaving mechanism comprises a base, a pneumatic device, an opening setting and tying system, an auxiliary looping assembly, a sinker assembly, a knitting needle assembly, needle selecting assemblies and needle pressing assemblies, wherein the opening setting and tying system, the auxiliary looping assembly, the sinker assembly, the knitting needle assembly, the needle selecting assemblies and the needle pressing assemblies are sequentially arranged from top to bottom. By matching of the opening setting and tying system, the auxiliary looping assembly, the sinker assembly, the knitting needle assembly, the needle selecting assemblies and the needle pressing assemblies, the requirements of automatic opening setting, opening tying, weaving and simple jacquard are achieved, and the problems that the weaving efficiency of the waistbands of the underclothes are low and the machine arrangement is wasteful are solved.

Description

technical field [0001] The invention belongs to the field of textile machinery, and in particular relates to a circular knitting machine for knitting underwear waist. Background technique [0002] Existing knitted underwear can be divided into two parts of the waist and the body structurally. There are two main stages in the waist weaving process: the beginning stage and the tie stage. The process of opening is: when weaving the first row, the knitting needles rise one by one and pad into the opening line. Due to the pushing action of the sinker, the yarn on the pad is pushed towards the center of the needle cylinder, so that the yarn is in the undeveloped position. The back of the raised knitting needles forms a one-by-one padding of yarn; when knitting the second row, all the knitting needles are inserted into the yarn; when knitting the third row, use the needle selection system to select one by three needles The 1st, 5th, and 9th needles go up and catch the yarn, and...
