Double nozzle multi-yarn weaving device

Abstract

The invention provides a double-nozzle multi-yarn weaving device, which includes a weft feeder, a main nozzle, a sub-nozzle, a heald frame, and a sliding module; the sub-nozzle is placed between the main nozzle and the warp opening; the The sliding module includes a sliding track, a spring, and a movable block. The auxiliary nozzle is slidably assembled on the horizontal sliding track. The auxiliary nozzle is connected to the movable block through a spring. The movable block is assembled on the frame. The lower part is designed with a knocking plate extending vertically downwards, and the front part of the knocking plate is designed with a cam that rotates from the axis, and a proximal end and a distal end are designed on the cam; the far end of the cam rotates Can be tapped onto the pad. In this way, the sub-nozzle can greatly increase the injection speed of the weft yarn, and also greatly improve the simultaneous conveying capacity of single or multiple weft yarns, and improve the surface quality of the gray cloth.

Description

technical field [0001] The invention relates to the technical field of weaving devices, 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. When the traditi...

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.
