Title:
WIRE WINDING REEL FOR THREE-DIMENSIONAL WOUND CORE TRANSFORMER
Document Type and Number:
WIPO Patent Application WO/2022/252498
Kind Code:
A1
Abstract:
Disclosed in the present invention is a wire winding reel of a three-dimensional wound core transformer, the wire winding reel comprising an outer reel, an inner reel and a tension assembly, wherein the outer reel is movably connected to the inner reel via a bearing assembly and rotates about an axis of the inner reel; the tension assembly comprises a screw rod, a spring and a connecting assembly; the connecting assembly comprises a fixing portion, a friction portion and a transmission portion, the friction portion and the transmission portion are both sleeved on the inner reel, and the transmission portion is fixedly connected to the outer reel; and a through hole is provided in a side surface of the inner reel, and the fixing portion passes through the through hole and is fixedly connected to the friction portion. By providing the outer reel and the inner reel, a foil strip wound around the outer reel can be stably and rapidly conveyed outwards as the outer reel rotates, and the winding efficiency of a three-dimensional wound core product is improved; and by providing the tension assembly, when the transmission portion is driven by the outer reel to rotate, the friction portion and the transmission portion generate a friction force, such that the outer reel applies tension to the foil strip or interlayer paper, the dislocation of the foil tape or the interlayer paper is avoided, and the coil quality is guaranteed.
