When the bobbin is extruded by the clamp plates three 54 and four 57, the bobbin is conveniently clamped by deforming the springs four and five. When the bobbin is taken out from the material rod, the first clamping arm 43 and the second clamping arm 44 can freely adjust the positions on the first sleeve 45 and the second sleeve 46, so that the bobbin can be conveniently taken down from the material rod. The mechanism can quickly take down and stack a yarn drum on the doffer, can continuously perform the operation, and has low fault-tolerant rate, high efficiency and greatly reduced labor force of workers.

Specifically, the second fixing frame 37 is fixed with a plurality of limiting pieces 60, and the limiting pieces 60 are used for limiting the first clamping arm 43 and the second clamping arm 44. The limiting piece 60 can limit the rotation angle of the first clamping arm 43 and the second clamping arm 44, so that the first clamping arm and the second clamping arm can move within a preset range.

Specifically, the third clamping plate 54 and the fourth clamping plate 57 are arc-shaped, and rubber pads are fixed on the third clamping plate 54 and the fourth clamping plate 57. The rubber pad can effectively prevent the yarn on the yarn barrel from being damaged by clamping. And meanwhile, the yarn cylinder can be prevented from slipping when being taken out.
