Improved single-arm yarn carrier

Abstract

The invention provides an improved single-arm yarn carrier comprising a shell consisting of a cover body and a base, a pivoting device arranged in the shell, a connecting piece connected with the pivoting device, a yarn guiding arm connected with the connecting piece and a yarn guiding eye arranged at the free end of the yarn guiding arm, wherein the pivoting device comprises a swing member; the swing member is provided with a body, as well as a first pivot shaft and a second pivot shaft which are integrally extended out of the body; at least one hook rod is arranged on the body; a spring is connected between the hook rod and the base; the swing member is arranged in the cover body and the base in a pivoting manner through the first pivot shaft and the second pivot shaft; and after penetrating through the cover body, the first pivot shaft is connected with the connecting piece so that the swing member can be interlocked with and drive the yarn guiding arm arranged on the connecting piece to swing through the first pivot shaft.

Description

technical field [0001] The invention relates to a yarn guide device of a knitting machine, in particular to a single-arm yarn guide device. Background technique [0002] Press, the existing knitting machine guides the yarn into the yarn feeding device through a yarn guide device, and then performs subsequent quantitative or variable yarn feeding operations, such as Chinese Patent Publication No. CN1690283, which discloses a single-arm The yarn guide rod device has a base and a cover that are mutually covered and consolidated on the outside of the yarn guide rod device, and a swing mechanism drives the yarn guide rod (yarn guide arm). [0003] The swinging mechanism includes a mandrel and a yarn guide rod, the mandrel is passed through the shaft hole on the cover body and connected with the base by a tension mechanism. The upper part of the mandrel is provided with an axial screw hole and a positioning groove passing through the screw hole transversely, and a transverse hole...

AI Technical Summary

Problems solved by technology

Since the connection between the mandrel and the yarn guide rod is only pressed by a single screw from the screw lock, the yarn guide arm will swing extremely momentarily during the fast yarn feeding operation, which makes the yarn guide rod easy to loosen or break after a period of use. Shaking instability, coupled with the fact that the mandrel needs to cooperate with the tension mechanism at the same time to transmit the tension of the extension spring, makes the bending part at the end of the connecting piece in the hole at the bottom of the mandrel easy to slide and loosen, and there will be friction. Affects the tension transmission of the mandrel and the tension spring
