Axial pay-off device capable of preventing shutdown wire accumulation

Abstract

The invention relates to an axial pay-off device capable of preventing shutdown wire accumulation. The axial pay-off device comprises a wire conveying assembly, a brake assembly, a steel pipe, a supporting cross rod and a bobbin; the brake assembly is coaxially embedded in the bobbin; the shell of the brake assembly and the bobbin are fixedly mounted together; the lower end of the steel pipe arranged vertically is coaxially and rotatably mounted in the brake assembly, while the upper end portion of the steel pipe is fixedly mounted together with the wire conveying assembly; the supporting cross rod is radially and fixedly mounted on the steel pipe above the bobbin; the wire conveying assembly, the supporting cross rod and the steel pipe all rotate around the central axis. The pay-off device has the advantages that a cylindrical pin in the brake assembly can be inserted in the through hole of a brake sleeve instantaneously upon shutdown in the mode of motion of putting the wire conveying assembly and the brake assembly in linkage by use of tractive force generated by a steel wire rope, and therefore, the steel pipe stops rotating immediately at the moment of shutdown so that the bobbin also is stopped from rotating immediately, and consequently, the problem of wire accumulation due to that the bobbin rotates continuously after shutdown is effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of steel wire rope production, and relates to a pay-off device for steel wire ropes, in particular to an axial pay-off device for preventing parking and stacking of wires. Background technique [0002] In the process of processing steel wire ropes, the wire ropes are generally paid off through an axial pay-off device, so that the entire steel wire ropes can be gradually straightened before drawing or tinning. [0003] However, when it is necessary to stop unwinding due to work or failure, the wire rope at this time has no traction, and the wire payoff will rotate several times due to inertia, which will cause the wire rope on the outer layer to loosen and pile down, resulting in The phenomenon of chaotic lines. [0004] After searching, I found a patent document related to the content of this patent, the Chinese patent with the publication number CN202492234U, which discloses a pay-off device, including a f...
