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. 1-3, the yarn breakage preventing and feeding disc for the knitted fabric comprises two guide discs 1 fixed through connecting rods, wherein adjusting cavities 12 are formed in the middle of the guide discs, a plurality of threading holes 11 communicated with the adjusting cavities 12 are formed in the guide discs 1 at equal intervals, and deflecting mechanisms 2 capable of deflecting in a self-adaptive mode to clamp broken yarns during yarn breakage are further arranged on the guide discs 1. Two groups of guide discs are arranged, so that broken yarns at two ends can be clamped and limited after the broken yarns are broken.

Wherein, as shown in fig. 2, the deflection mechanism 2 includes a T-shaped guide rod 21 rotatably disposed on the guide disc 1 and extending into the adjustment chamber 12, a torsion spring 22 inserted at both ends of the T-shaped guide rod 21 and the guide disc, and a connecting rod 23 fixed at one end of the T-shaped guide rod 21 extending into the adjustment chamber 12, wherein the connecting rod 23 is provided with a threading slot 3 with an open end for threading yarn, and a rubber ring 31 fixed in the adjustment chamber 12 for tightly attaching to the yarn after restoration to play a clamping role in the rotation direction of the restoration of the connecting rod 23.

Referring to fig. 4 and 5, one end of the connecting rod 23 corresponding to the threading slot 3 is sleeved with a clamping block 4 which can reset and slide axially when yarn is broken, a corresponding threading slot is also formed in the clamping block 4, meanwhile, the corresponding end side of the connecting rod 23 is rotatably connected with a movable block 24, and the movable block 24 is embedded into the clamping block 4 and can drive the movable block 24 to close and clamp yarn when the clamping block 4 resets.
