The invention is realized by adopting the following technical scheme:
reduce tensile of air jet loom slitter edge yarn length and assist system of spouting, including the steel sley is gone up from a left side to the right side fixed in proper order and is set up to assist and spout device, photoelectricity weft feeler (H1) and tensile assistance and spout the passageway, the assistance spout the device and include spray tube and base, the base on be equipped with the mounting hole, the spray tube passes the mounting hole and fixes on the base, the spray tube connect gradually the constitution from bottom to top by pipe, transition pipe and flat pipe, flat pipe and the perpendicular setting of reed seat, flat pipe top horizontal be equipped with the nozzle, the nozzle be 4-8mm to the distance of mounting hole the central axis, the air outlet of nozzle is facing to photoelectricity weft feeler and tensile assistance and is spouted the passageway.
The photoelectric weft feeler is arranged in contact with the stretching auxiliary spraying channel to guide the sprayed airflow and avoid the dispersion of the airflow.
The distance between the nozzle and the photoelectric weft feeler is 2mm, so that the flying distance and time of weft yarns can be ensured, and the length of waste selvage yarns is shortened under the premise of normal action of the photoelectric weft feeler.
The base on be equipped with the fixed orifices with the mounting hole intercommunication, threaded connection has the jackscrew in the fixed orifices, fixes the spray tube through the jackscrew.
The base is provided with a connecting hole, and the auxiliary spraying device can pass through the connecting hole through a bolt to fixedly install the base on the steel sley.
The bottom of the auxiliary spraying device is connected with a loom air pipe.
Compared with the prior art, the invention has the following beneficial effects:
1. according to the invention, the stretching auxiliary spraying channel is arranged behind the photoelectric weft feeler, so that weft can be tensioned and cannot retract to a weaving opening, normal interweaving of the weft and edge catching yarn is ensured, weft shrinkage formation is reduced, and weaving quality is ensured.
2. According to the invention, by improving the structure of the auxiliary spraying device, the nozzle is arranged at the upper right part, so that straight weft yarns can be sprayed forwards along with airflow, and the weft yarns are ensured to be difficult to retract.
3. The distance between the nozzle and the photoelectric weft feeler is set to be 2mm, so that the flying distance and time of weft can be ensured, the length of waste selvage yarns is shortened under the premise of normal action of the photoelectric weft feeler, and the length of the waste selvage yarns can be reduced by more than 2 cm.
4. According to the invention, the upper part of the auxiliary spraying device is provided with the flat pipe, so that the airflow of the air outlet can be increased, and the weft yarn is further ensured not to retract easily.
