Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of wire unwinding anti-sticking structure. BACKGROUND

[0002] When the electric wire is transported to the processing equipment, the reel is in the state of axial vertical, and the electric wire on the reel is unwound upward by the external power source and guided to the processing equipment through the wire guide. In the process of unwinding the electric wire upward, the electric wire is easy to rub with the rim of the reel or even be stuck on the rim. Since a large amount of electric wire is wound on the reel, the reel is heavy and cannot rotate smoothly by itself, so when the electric wire is stuck on the rim, it will cause the unwinding to be not smooth, and it may cause damage to the surface of the electric wire.

[0013] Compared with the prior art, the wire unwinding anti-blocking structure has the following beneficial effects: the wire rotating disc is additionally arranged on the top of the winding disc, and the outer diameter of the wire rotating disc is greater than the outer diameter of the winding disc, so that the wire unwinding upwards contacts the periphery of the wire rotating disc, when the wire and the periphery of the wire rotating disc have large friction or are blocked at the edge, the upward tension of the wire can make the wire rotating disc adaptively rotate actively, so that the wire is prevented from being blocked at the periphery of the wire rotating disc and the surface of the wire is prevented from being damaged, and smooth wire unwinding is realized.
