Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

Referring to fig. 1-4, the yarn breakage preventing yarn guide drum mechanism for the hosiery machine comprises a yarn guide drum 1, wherein the yarn guide drum 1 comprises a lower drum 11 and an upper drum 12 which are connected in an opposite direction, a yarn guide hole 13 is formed in the middle of the opposite surface of the lower drum 11 and the upper drum 12, yarn guide rubber rings 14 are arranged in the yarn guide holes 13 at the two ends of the lower drum 11 and the upper drum 12 and used for penetrating yarns 0, and the yarn guide rubber rings 14 are clamped between the lower drum 11 and the upper drum 12; the middle part of the lower barrel 11 is provided with an adjusting groove 3 which is arranged in a penetrating way, the adjusting groove 3 is internally provided with a thread passing plate 4 which can be jacked upwards in a self-adaptive mode when a thread is broken, the middle part of the thread passing plate 4 is provided with a thread way 41 for a yarn 0 to pass through, a pressing plate 5 is fixed at the bottom of the upper barrel 12 corresponding to the thread way 41 (the pressing plate 5 can be directly welded on the upper barrel 12), and the size of the pressing plate 5 is matched with the thread way 41, so that the pressing plate 5 can extend into the thread way 41 and be attached to the surface of the thread way 41.

With further reference to fig. 2 and 3, the bottom of the adjusting groove 3 and the bottom of the wire passing plate 4 are both provided with spring mounting seats 31, and a compression spring 32 is sleeved in the spring mounting seats 31, and the compression spring 32 applies a compression force when the yarn 0 passes through the yarn path, so that the yarn path 41 has a certain interval with the compression plate 5. In this embodiment, the yarn path 41 is an arc-shaped yarn path, which is convenient for supporting yarn and applying downward pressure to the yarn passing board 4, so as to better extrude the pressing spring 32. Meanwhile, the pressing plate 5 is also in an arc-shaped convex shape, so that the yarns in the yarn channel 41 can be better extruded.
