Description
Technical Field
[0001] The utility model relates to the field of yarn guides, in particular to a yarn guide for a flat knitting machine. Background Art
[0002] The yarn guide includes a yarn guide base and a yarn guide hook. The yarn guide base is provided with a yarn guide through groove, and the yarn guide hook is fixedly connected to the upper opening edge of the yarn guide through groove, and the yarn guide hook partially shields the upper opening of the yarn guide through groove. Yarn guides need to be respectively arranged near the yarn feeding bobbin and near the yarn basket on the frame. The yarn of the yarn feeding bobbin is led through the yarn guide near the yarn feeding bobbin, so that the moving path of the yarn faces the yarn basket above the frame.
[0003] When the existing yarn guide for a flat knitting machine is in use, the yarn is traction-limited by the yarn guide hook. However, the number of yarns that can be selected when the flat knitting machine is working is not unique. The winding of multiple yarns will increase the thickness of the synthetic yarn, and the thicknesses of different yarns are also different. The yarn guide hook can only simply limit the yarn. When the yarn is too thin, it is difficult to achieve the limiting effect, and if the yarn cannot be tightened, it is easy to cause the yarn to be wound together. Summary of the Utility Model

[0016] The utility model has the following beneficial effects:
[0017] 1. Compared with the prior art, for this knitting flat knitting machine yarn guide, through the handle, the second bevel gear, the first bevel gear, the threaded rod, the moving block, the first connecting bar, the second connecting bar, the first pin, the second pin, the first limiting ring, the fixed shaft and the second limiting ring, turning the handle can drive the second bevel gear to rotate, which in turn drives the first bevel gear to rotate, then drives the threaded rod to rotate, and then drives the moving block to move downward, which in turn drives the first connecting bar and the second connecting bar to move downward, then drives the first pin and the second pin to move downward, and then drives the first limiting ring to rotate clockwise around the fixed shaft and the second limiting ring to rotate counterclockwise around the fixed shaft. Thus, the space between the first limiting ring and the second limiting ring can be controlled, which is convenient for traction and limitation of yarns with different thicknesses. Compared with the existing knitting flat knitting machine yarn guides, when in use, the yarn is traction-limited by a yarn guide hook. However, the number of yarns that can be selected when the knitting flat knitting machine is working is not unique. Wrapping of multiple yarns will increase the thickness of the synthetic yarn, and the thicknesses of different yarns are also different. The yarn guide hook can only perform simple limitation on the yarn. When the yarn is too thin, it is very difficult to achieve the limiting effect, and if the yarn cannot be tightened, it is very easy for the yarn to get tangled together. This knitting flat knitting machine yarn guide can control the space between the first limiting ring and the second limiting ring, which is convenient for traction and limitation of yarns with different thicknesses.
[0018] 2. Compared with the prior art, for this yarn guide of a knitting flat knitting machine, through the sliding strip and the yarn guide body, the sliding strip can effectively reduce the friction between the yarn and the yarn guide body, avoiding the situation where the yarn breaks due to friction.
