Driving device of weft faller gill of crochet machine

Abstract

The invention discloses a driving device of a weft faller gill of a crochet machine. The driving device can enable weft to be fixed firmly. The driving device comprises a horizontal driving shaft rotationally arranged on a machine frame, a rotating base arranged on the machine frame to rotate around the horizontal axis, and the rotating central line of the rotating base is perpendicular to the driving shaft; the driving shaft is fixedly sleeved with an eccentric wheel, a transmission base is connected to the periphery of the eccentric wheel through a bearing, an installation base parallel to the driving shaft is movably arranged in the transmission base in a penetrating mode, the end, penetrating out of the transmission base, of the installation base is provided with the weft faller gill, and a connecting rod is hinged to the other end, penetrating through the transmission base, of the installation base; a cam is arranged on the rotating base, a transmission piece is hinged to the machine frame, one end of the rotating piece makes contact with the periphery of the cam, the end of the connecting rod is hinged to the other end of the transmission piece, the contact position of the transmission piece and the cam, the hinged position of the transmission piece and the machine frame and the hinged position of the transmission piece and the connecting rod are in a triangular shape; the periphery of the cam is divided into three driving hook face sections.

Description

technical field [0001] The invention relates to a driving device for a weft needle plate of a crochet machine. Background technique [0002] The crochet machine is to weave the warp yarn and weft yarn into the "cloth" of warp knitting and weft insertion, and then cut the cloth into strips (only cutting the weft yarn) by a blade. Or use warp yarn and weft yarn to directly weave into the tape-shaped yarn of warp knitting weft insertion organization. The feature of crochet fancy yarn is that the warp yarn is continuously looped, the weft yarn is used as a pad, and the yarn is formed into a flat shape. [0003] The weft yarn knitting of common crochet machine is to drive weft yarn by the weft yarn needle that is installed on the weft yarn needle plate. The weft needle is a device fixedly installed on the weft needle plate to guide the weft yarn to complete the weaving action. The head of the weft needle is a hollow tube in the middle, and the weft yarn moves with the movement...

AI Technical Summary

Problems solved by technology

[0005] For ordinary yarn, the warp yarn is continuously looped, and the weft yarn is fixed by the left and right warp yarns while swinging left and right under the drive of the weft needle, and then the weft yarn is divided into two by the middle blade. The warp yarn is only wound around once, the fastness of the weft yarn and warp yarn is not very good, and it is easy to cause the weft yarn to lose hair during use
