Paying-off device for wire of excessively small diameter

Abstract

The invention discloses a paying-off device for a wire of an excessively small diameter. The paying-off device for the wire of the excessively small diameter structurally comprises locking pieces, a rotating shaft, a tension adjusting device, a paying-off disk, a loading and unloading frame, rotating wheels, locking bolts, a wire outlet hole, a traction guide roller and a paying-off body. When thepaying-off device for the fine wire starts to pay off the wire with the diameter smaller than 0.05 mm, the pressure and friction force between the paying-off disk and a tray are reduced, so that theconstraint borne by the paying-off disk during rotation is reduced; when paying-off is stopped, the pressure and friction force between tension wheels and a tension disk are increased, the rotating wheels are controlled through nitrile rubber mats, the tension disk assists the tray to adjust the speed of the paying-off disk, so that the paying-off disk and the rotating wheels evenly reduce the paying-off speed until stop, the tension change degree during paying off is reduced, the quality and yield of the wire are guaranteed, and the production efficiency and the paying-off efficiency of the wire are improved.

Description

technical field [0001] The invention relates to the field of wire pay-off, in particular to a wire pay-off device for wires with too small diameter. Background technique [0002] The pay-off device is a device used in the pay-off process of cables, bare wires, etc. When the wire diameter is less than 0.05 mm, it is inevitable that there will be breakage when paying off, especially at the moment when starting or stopping the wire, the tension of the wire will change rapidly when the pulling speed of the wire becomes faster or slower. , leading to wire breakage in the process of unwinding, which reduces the quality and pass rate of the wire, and affects the production of the wire and the efficiency of unwinding. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a wire pay-off device for wires with too small diameters, so as to solve the problem that the wire diameter of the existing pay-off rack...

[0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a wire pay-off device for wires with too small diameters, so as to solve the problem that the wire diameter of the existing pay-off racks cannot It is inevitable that there will be breakage when the wire less than 0.05 mm is paid out, especially at the moment when the wire is started or stopped, because the pulling speed of the wire becomes faster or slower, the tension of the wire changes quickly, resulting in The wire breakage phenomenon occurs during the pay-off process, which reduces the quality and pass rate of the wire, and affects the production of the wire and the efficiency of the wire release.
