Description

Technical Field

[0001] The utility model relates to the technical field of enameled wire processing, in particular to an enameled wire surface lubricating oil coating device. Background Art

[0002] During the production and processing of enameled wire, it is necessary to apply lubricating oil to the surface. The existing oiling device uses an oil pump to regularly add lubricating oil to the oil storage box, and the felt siphons the lubricating oil in the oil storage box, and the felt works by coating the lubricating oil on the surface of the enameled wire.

[0003] However, the existing oiling device cannot quantify the amount of oil applied, and the amount of oil applied to the surface of the enameled wire is uneven. When the oil pump fills the oil storage box, the amount of oil applied will go through a cycle of continuous decrease from a large amount, and then increase again at the next oil pumping point. In addition, the existing oiling device does not have an alarm. When the surface of the enameled wire is not coated with lubricating oil, the existing oiling device will not sound an alarm, which is easy to cause scrapped products and affect product quality.
