The other end of the supporting rod 1 is vertically provided with a connecting rod, and the tray 2 is horizontally arranged and is rotatably sleeved on the connecting rod through a bearing. The middle of the tray 2 is vertically provided with a central shaft 21, the core of the yarn cylinder 5 is sleeved on the central shaft 21, and the bottom of the yarn cylinder 5 is supported by the tray 2.

The buffer device 3 comprises a telescopic cylinder 31, a push block 32, a contact sensor, an installation rod 33 and a slide block 34, wherein the telescopic cylinder 31 is installed on the support rod 1, the telescopic direction is vertical to the support rod 1, and the push block 32 is installed at the telescopic end of the telescopic cylinder 31. The contact sensor is arranged on one side of the push block 32, which is far away from the telescopic cylinder 31, the mounting rod 33 is arranged on the side edge of the supporting rod 1, the slide block 34 is arranged on the mounting rod 33 in a sliding mode and is perpendicular to the supporting rod 1, and the slide block 34 can be abutted to or separated from the push block 32. The slider 34 is provided with a thread-drawing hole 341, and the yarn 51 passes through the thread-drawing hole 341 and the thread-outlet hole 11 in sequence.

The working process of the utility model is as follows: the yarn cylinder 5 is sleeved on the central shaft 21, the yarn 51 sequentially penetrates through the wire drawing hole 341 and the wire outlet hole 11, in the machining process, along with the fact that the length of the yarn 51 between the wire outlet hole 11 and the tray 2 is gradually reduced, the yarn 51 in the wire drawing hole 341 pushes the sliding block 34 to enable the sliding block 34 to slide to the pushing block 32, when the sliding block 34 abuts against the pushing block 32, the contact sensor works to enable the telescopic cylinder 31 to stretch out, the pushing block 32 pushes the sliding block 34 to slide in the direction far away from the telescopic cylinder 31, meanwhile, the sliding block 34 pulls the yarn 51 in the wire drawing hole 341 to enable the tray 2 and the yarn cylinder 5 to rotate, and therefore the yarn 51 is pre-pulled out.

According to the yarn feeding mechanism provided by the embodiment of the utility model, the rotatable tray 2 is arranged, so that the rotating stability and smoothness of the yarn drum 5 are improved, and the yarn 51 is pre-pulled out by arranging the buffer mechanism, so that the probability of breaking the yarn 51 is reduced.
