Description

Technical Field

[0001] The utility model relates to the field of enameling machines, in particular to a wire-releasing mechanism and an enameling machine thereof. Background Art

[0002] The enameling machine is a device used to coat insulating varnish on the surface of metal conductors. It is usually composed of a pay-off device, an annealing device, a painting device, a baking device, a wire-reeling device, etc. The working principle of the enameling machine is to pay out the metal conductor from the pay-off device, anneal it in the annealing device, and then enter the painting device to coat a uniform layer of insulating varnish on the surface of the conductor, and then bake it in the baking device to solidify the insulating varnish, and finally reel it in by the wire-reeling device. The advantages of the enameling machine are uniform coating, stable quality, and high efficiency, which can meet the production of enameled wires of different specifications and requirements.

[0003] When the wire pay-off device on the enameling machine is working, the wire drum is usually installed on a rotatable shaft, and in order to ensure the stability of the wire drum installation, the wire drum is usually locked by a limit disc and a locking nut. However, the wire drum is restrained by the locking nut. When the wire drum is replaced, the employee needs to manually rotate and remove the locking nut. When the locking nut is too tight, it is necessary to use a wrench to remove it, thereby reducing the convenience of replacing the wire drum. Utility Model Content
