Double-spray-nozzle multi-yarn weaving device

Abstract

The invention provides a double-spray-nozzle multi-yarn weaving device. The double-spray-nozzle multi-yarn weaving device comprises weft storage units, a main spray nozzle, a secondary spray nozzle, a heald frame and a sliding module; the secondary spray nozzle is arranged between the main spray nozzle and the warp opening position; the sliding module comprises a sliding rail, springs and an active block, the secondary spray nozzle is assembled on the horizontal sliding rial in a sliding mode, the secondary spray nozzle is connected with the active block through the springs, the active block is assembled on a rack, the lower portion of the secondary spray nozzle is designed with a knocking plate which perpendicularly extends downwards, the front part of the knocking plate is designed with a cam which rotates around the axis, and the cam is designed with a near end and a far end; the far end of the cam can knock on the knocking plate during rotating. In this way, the secondary spray nozzle can greatly increase the jet velocity of weft yarn; meanwhile, simultaneous conveying capacity to a single weft yarn and multiple weft yarns is greatly improved, and the cloth cover quality of gray fabric is improved.

Description

technical field [0001] The invention relates to the technical field of textile machinery and equipment, in particular to a double-nozzle multi-yarn weaving device. Background technique [0002] Textile fabrics are usually woven by alternate warp threads and weft threads. During the weaving process, the warp threads are usually divided into two parts that open up and down by the heald frame, and the weft threads pass through the middle. In the past, the threading action of the loom was usually performed by a belt With the development of society, the textile equipment is also changing with each passing day. In the current spinning equipment, the shuttle is used less and less. The current weaving equipment usually uses the air-jet loom with a new weft threading structure. , Water jet loom. The weft threading process of the air-jet loom is completed by the high-pressure airflow driving the weft thread through the gap between the two warp threads controlled by the heald frame. ...

AI Technical Summary

Problems solved by technology

Due to the instability of the air flow on the traditional air-jet loom, the fabric is prone to defects such as lack of weft, hundreds of feet, and weft shrinkage after the gray fabric is unloaded, and the quality of the fabric surface cannot be guaranteed.

Especially when multiple weft threads are aggregated together and pass through the opening of two warp threads, it is often difficult to carry out the weft threading operation when multiple weft threads are together, which greatly increases the probability of problems on the cloth surface, and the loose weft threads make the cloth surface more prone to wear and tear.
