The utility model relates to a weft creel of a weaving machine with a multi-spray device. Yarn insertion spindles are mounted on a rear creel of a triangular columnar weft creel; the multi-spray device is mounted on a front creel of the triangular columnar weft creel; an electronic single-yarn prevention device is mounted at the front end of right-angled soldering iron of the multi-spray device; an open type glass-tube yarn guide device is mounted at the middle part of the right-angled soldering iron of the multi-spray device; and a mechanical single-yarn detection device is mounted at the tail end of the right-angled soldering iron of the multi-spray device. An insulating rubber gasket hole is formed in the front end of the mechanical single-yarn detection device, a yarn outgoing hole is formed in the tail end of the mechanical single-yarn detection device, a detection right-angled forearm is fixed on the mechanical single-yarn detection device after passing through the rubber gasket hole, the detection right-angled forearm is connected with the positive pole of a power source, and an iron sheet capable of rotating up and down is connected with the negative pole. When a weft yarn breaks, the electronic single-yarn detection device can detect the situation; when the operation environment is not suitable for detection and the situation is not detected, the rotating iron sheet on the mechanical single-yarn detection device falls down rapidly to form a circuit so as to realize shutdown. A round disc of the glass-tube yarn guide device is adjusted, so tension of all yarns is identical and tense and loose yarns can be avoided. According to the weft creel, in case that a weft yarn breaks, judgment can be made correctly and timely shutdown can be ensured, so the warehouse first-class rate can be ensured.
