Oil detecting and alarming system for sewing machine

The utility model provides an oil detecting and alarming system for a sewing machine. The oil detecting and alarming system comprises a liquid level sensor, an oil stabilizer, a signal processing module, and a display. The oil stabilizer comprises a cylinder; the top end of the cylinder is provided with an air hole; the bottom end of the cylinder is provided with an oil hole; the oil stabilizer is arranged in an oil receiver of the sewing machine; the liquid level sensor is arranged inside the cylinder of the oil stabilizer; the liquid level sensor is connected with the signal processing module; the signal processing module is connected with the display. The oil detecting and alarming system has the advantages that the oil stabilizer can effectively control surface fluctuation of oil in the oil receiver, caused by operation of an oil pump and mechanical vibration, and the liquid level sensor can detect oil volume precisely; detection signals of the liquid level sensor are transmitted to the signal processing module; when the oil volume is minimum, the signal processing module transmits an alarm signal to the display, the display sends out a warning in time, the interference of mistaken warning upon normal operation of the sewing machine is avoided, sufficient lubrication is guaranteed for a sewing machine drive system, and the service life of the sewing machine is prolonged.
