Spray device for producing polyester silk pieces

The utility model discloses a spray device for producing polyester silk pieces. The spray device is characterized in that an interval is arranged between an upper bathing groove and a lower bathing groove, multiple oil spray pipes are respectively arranged in the upper bathing groove and the lower bathing groove, multiple downward upper nozzles are arranged on the oil spray pipes in the upper bathing groove, multiple upward lower nozzles are arranged on the oil spray pipes in the lower bathing groove, the polyester silk pieces penetrate through the interval, and oil spray is carried out on the polyester silk pieces through the upper nozzles and the lower nozzles. Through the arrangement, oil is uniformly sprayed on the polyester silk pieces, thus the polyester silk pieces reach the drafting temperature evenly, drafting performance of the polyester silk pieces is improved, and a phenomenon of drafting roller winding of a back-end working procedure is greatly reduced.
