Device for coating lubricant on varnished wire

The utility model discloses a device for coating lubricant on an enamelled wire. The device for coating the lubricant on the enamelled wire includes an enamelling machine, a wire coiling shaft and a lubricating liquid box. The bottom part of the inner wall of the lubricating liquid box is provided with a liquid level sensor. The liquid level sensor is connected with an input terminal of a controller. An output terminal of the controller is connected with an alarm device. By adopting the above structure, the device for coating the lubricant on the varnished wire has the following advantages. First, after the lubricating liquid in the lubricating liquid box runs out, the level sensor collects signals and transmits the signals to the controller. The controller processes the signals and controls an alarm light to alarm. A worker sees the alarm light and can fill the lubricating liquid into the lubricating liquid box timely, thereby avoiding accidents of missing the coating of the lubricant on the enameled wire. S
