Yarn pressing device and working method of flat knitting machine

Abstract

The invention relates to a yarn pressing device for a flat knitting machine and a working method thereof. A sinker is installed in a sinker receiving groove; the sinker includes a sinker body, an elastic presser foot part, a power plate heel and a yarn pressing part; the sinker There are three rotation positioning holes on the body, and a limiting through hole on the yarn pressing part; there are three through grooves on the sinker needle plate, and a No. 1 positioning steel wire is installed in each through groove. No. 1 positioning steel wires are respectively passed through three rotation positioning holes; the axis center lines of the three No. 1 positioning steel wires are not on the same straight line as the three intersection points generated by the same cross section. The three intersection points determine a virtual circle, and the center of all virtual circles A virtual axis is formed; the heel of the power plate causes the sinker to rotate forward and backward around the virtual axis under the action of power. This yarn pressing device reduces the requirements for the use of rollers, presser feet and other flat knitting machines during knitting, facilitates the optimization of the structural design of the integrated garment machine, and is conducive to controlling the overall production cost.

Description

technical field [0001] The invention relates to the technical field of computerized flat knitting machines, in particular to a yarn pressing device of a flat knitting machine and a working method thereof. Background technique [0002] Computerized flat knitting machines need to be filled with a large amount of yarn when weaving. In order to prevent yarn floating, yarn pressing devices are usually installed on the front and rear needle beds to press the yarn so that it does not float up. The sinker in the existing yarn pressing device is usually Threaded on a positioning steel wire, as shown in the patent application with publication number CN111005143A, under the power drive, the sinker rotates with the positioning steel wire as the rotating shaft, and the sinker with this structure still has the possibility of forming loops and floating pieces High shortcomings, so it is necessary to improve and optimize it.
