Spindle cleaning oil feeder

The utility model relates to a spindle cleaning and oiling machine in textile industry, which comprises a cleaning oil ejector, a negative pressure source, a filtrating device, and an oil tank. The cleaning oil ejector comprises a sleeve barrel with an opened lower end and a piston, and the two parts are supported by a spring and interstitially matched. An annular groove is arranged outside the upper section of the piston, a cavity with a downward opening is arranged inside the lower section, an annular groove and a sliding chute are peripherally arranged on the outside, and through holes communicated with the cavity are arranged on the groove. The passage inside the middle section of the piston is communicated with the cavity, and penetrates through the side wall of the piston, and an oil filler pipe is connected with one end where the passage and the cavity are communicated. A locating pin fixed and arranged under the sleeve barrel extends into the sliding chute, two through holes on the sleeve barrel are separately connected with the oil tank and the oil absorption opening of negative pressure source, and the filtrating device is connected between an oil outlet opening of the negative pressure source and the oil tank. The cleaning and oiling machine has the advantages that the quantity of hydraulic elements is small, the phenomenon of pipeline explosion, oil leakage, or oil injection does not exist, the work efficiency is high, the cleaning and oiling machine has energy saving and environmental protection.
