Automatic pressure-reducing type bobbin loader

Abstract

The invention relates to an automatic pressure-reducing type bobbin loader and belongs to the field of auxiliary equipment for drawing and coiling steel wires. The automatic pressure-reducing type bobbin loader comprises a disc-shaped base plate and a conical drum wound with steel wires, wherein the drum is fixed on the base plate; a hollow protecting pillar is fixed at the center of circle of thebase plate; a rotating shaft is arranged in the protecting pillar; one end of the rotating shaft is fixedly connected with a plane bearing while the other end is fixedly connected with the rotating shaft of the plane bearing (decelerating effect) through a nut; the lower end of the plane bearing is fixed with the base plate; the lower end of the plane bearing is arranged on the base and is connected with the interior of the base. The structure is simple and the practicability is high; on the basis of the conical design of the drum, the self-adaptive tensioning of the steel wires is realized under the effects of the cycle number increasing and the gravity increasing and the balancing of the tensioning force index is realized; under the effects of the pressure bearing of the plane bearing on the lower part and the speed reduction of the plane bearing on the upper part, the disordered and broken wires are greatly reduced; the subsequent working pressure is also relieved; the working efficiency and the product quality are obviously increased; the potential safety hazard existing in the working process is reduced.

Description

technical field [0001] The invention belongs to the field of auxiliary equipment for wire drawing and take-up of steel wires, and in particular relates to a self-decompression wire reel rack. Background technique [0002] At present, the main function of the wire reel frame is to wind the electric wire, cable or steel wire on the barrel of the reel, and then use the wound electric wire, cable or steel wire after defense. The existing reels are all wound in a straight cylinder, which is okay for wires and cables, but when the fine metal wires are drawn and then used to take up the wires, the wires are broken in the middle of the winding process, and the wire winding is too common. With the continuous increase of steel wires, coupled with the effect of gravity, a greater pressure will be exerted on the lower part of the reel, and the outer diameters of the upper and lower ends are different, which makes it difficult to transport after the winding is completed, increasing the ...

Problems solved by technology

The existing reels are all wound in a straight cylinder, which is okay for wires and cables, but when the fine metal wires are drawn and then used to take up the wires, the wires are broken in the middle of the winding process, and the wire winding is too common. With the continuous increase of steel wires, coupled with the effect of gravity, a greater pressure will be exerted on the lower part of the reel, and the outer diameters of the upper and lower ends are different, which makes it difficult to transport after the winding is completed, increasing the There is a great potential safety hazard in the case of uneven stress on the boom of the crane

And because the internal pressure generated by the steel wire itself is easy to break in the middle, which reduces the work efficiency and is very inconvenient
