Abstract

The utility model relates to a yarn feedind cutting structure for a thread adjuster and belongs to an inner yarn feeding device of a thread adjuster for a knitting machine. The yarn feedind cutting structure for a thread adjuster comprises an outer plate, a yarn feeding finger and a yarn cutter, wherein two push-and-pull rods arranged in a parallel manner are movably installed in the middle portion of the outer plate via a pin shaft; a yarn cutter swing arm and an actuating arm are respectively installed on the lower portions of the push-and-pull rods via a pendulum shaft; a pressing head of one of the push-and-pull rods is movable fit with the yarn cutter swing arm; a pressing head of the other push-and-pull rod is movable fit with the actuating arm; the yarn cutter is installed at the lower end of the yarn cutter swing arm; the yarn feeding finger is fixed at the bottom portion of the outer plate; a yarn setting hole is mounted at the bottom portion of the yarn feeding finger; and yarns led out from the yarn setting hole are exactly positioned on the swing track of the edge of the yarn cutting cutter. The yarn feeding cutting structure for a thread adjuster overcomes a shortcoming that movement of the yarn feeding finger is fixed by a traditional thread adjuster cutter, and leads the yarn feeding finger to fixedly depend on the swing of the cutter to clamp and cut yarns; can avoid flying of yarns caused by yarn skipping in a yarn changing process, thereby ensuring stability of yarn feeding and cutting of the thread adjuster, and simplifying debugging procedure of machines.

Description

The knot structure is cut in the yarn changing device yarn feeding

Technical field:

The utility model relates to the yarn changing device yarn feeding and cuts the knot structure, belongs to the inner yarn feeding device of knitting machine yarn changing device.

Background technology:

Existing yarn changing device, it is to refer to swing by yarn feeding that yarn principle great majority are cut in its yarn feeding, with the feeding of the yarn that weaving fixing cut the yarn edge of a knife, finish the task of folder (cutting) yarn, though some yarn changing devices adopts movable blade to cut yarn, yarn feeding complex structure and do not manage yarn hole (folder) and cut the yarn cutter when cutting yarn and can certain influence be arranged to the yarn of duty.Yet, when yarn can be along with the rhythm of knitting needle is slightly beated in the braiding process, change yarn at yarn changing device and receive that yarn feeding refers to drive the yarn swing when referring to, can aggravate beating of yarn in the motion process, needing to finish yarn clipping in this state cuts yarn and just the Installation and Debugging of yarn changing device is proposed higher requirement, cut less than yarn as debugging improper just might causing slightly, fly the yarn phenomenon; Even debugging puts in place also unstable when running up.

The utility model content:

The utility model is intended to address the above problem, and can guarantee that the yarn changing device yarn feeding cuts the stability of yarn and provide a kind of, simplifies the yarn changing device yarn feeding of board debug process and cuts the knot structure.

The technical solution adopted in the utility model is: the knot structure is cut in a kind of yarn changing device yarn feeding, comprise outside plate, yarn feeding refers to, cut the yarn cutter, this outside plate middle part is movably installed with two pull bars that be arranged in parallel by bearing pin, two pull bars below is equipped with by balance staff respectively and is cut swing arm of yarn cutter and transmission arm, the pressure head of one of them pull bar with cut the swing arm of yarn cutter movingly, the pressure head of another pull bar and transmission arm are movingly, cutting the yarn cutter is loaded on and cuts yarn cutter swing arm lower end, yarn feeding refers to be fixed on the outside plate bottom, yarn feeding refers to that the bottom is provided with reasonable yarn hole, and the yarn of being derived by this reason yarn hole is positioned on the track of cutting the swing of the yarn cutter edge of a knife just.

Compared with prior art, the beneficial effects of the utility model are: overcome traditional yarn changing device cutter fixedly yarn feeding refer to movable drawback, yarn feeding by the reasonable yarn of fixed band hole refers to avoid changing in the yarn process because the generation that flies the yarn phenomenon that yarn is beated and caused, thereby guarantee the stability that yarn is cut in the yarn changing device yarn feeding, simplified the board debug process.

Among the figure: locate fast 1, outside plate 2, threading board 3, yarn feeding refers to 4, yarn cutter 6 is cut in reason yarn hole 5, transmission arm balance staff 7, transmission arm 8 is cut yarn cutter swing arm 9, cuts yarn cutter swing arm balance staff 10, transmission arm pull bar 11 is cut yarn cutter swing arm pull bar 12, bearing pin 13.

The specific embodiment:

The utility model is described in further detail below in conjunction with embodiment that accompanying drawing provides.

As shown in Figure 1, it is fast 1 that the top of this outside plate 2 is fixed with the location, and the yarn feeding of this yarn changing device is cut the knot structure and located fast 1 integral installation on machine by this.The middle part of this outside plate 2 is movably installed with the transmission arm pull bar 11 that be arranged in parallel and cuts yarn cutter swing arm pull bar 12 by bearing pin 13, this is cut yarn cutter swing arm pull bar 12 belows and is equipped with and cuts yarn cutter swing arm 9 by cutting yarn cutter swing arm balance staff 10, transmission arm 8 is equipped with by transmission arm balance staff 7 in these transmission arm pull bar 11 belows, this is cut the pressure head of yarn cutter swing arm pull bar 12 and cuts yarn cutter swing arm 9 movingly, the pressure head of this transmission arm pull bar 11 and transmission arm 8 are movingly, cutting yarn cutter 6 is loaded on and cuts yarn cutter swing arm 9 lower ends, yarn feeding refers to that 4 are fixed on outside plate 2 bottoms, yarn feeding refers to that 4 bottoms are provided with reasonable yarn hole 5, and the yarn of being derived by these reason yarn 5 holes is positioned on the track of cutting the swing of yarn cutter 6 edges of a knife just.

During work, earlier knitting yarn is passed threading board 3 and refer to that along yarn feeding the reason yarn hole 5 feeding knitting needles on 4 weave.

When cutting yarn cutter swing arm pull bar 12 and pushing ahead, drive and cut yarn cutter swing arm 9 and swing to assigned address (as shown in Figure 2), wait for that the Yarn guide mechanism on the knitting machine finishes the guide task this moment around cutting yarn cutter swing arm balance staff 10.

When guide was finished, transmission arm pull bar 11 moved backward, impelled that transmission arm 8 is stressed cuts yarn cutter 6 to pressing down, and put cutter operation (as shown in Figure 3).

When finishing braiding, cutting yarn cutter swing arm pull bar 12 is drawn out, drive is cut yarn cutter swing arm 9 and is swung to and cut the yarn position, cutting yarn cutter 6 edges of a knife this moment contains from yarn feeding and refers to the yarn (as shown in Figure 4) that comes out in 4 reason yarn holes 5, this time, the transmission arm pull bar 11 was drawn out, and impelled transmission arm 8 to drive to cut yarn cutter 6 closures to finish tongs yarn action (as shown in Figure 5).
