Problems solved by technology

The weft yarn unwound from the weft feeder penetrates along the center line of the main nozzle, and flies into the weft insertion airflow channel under the action of the compressed air sent by the main air pump. After the high-pressure gas is ejected, the airflow is seriously diffused. , causing the flow rate to drop rapidly, the weft yarn cannot fly out smoothly, which seriously affects the quality and efficiency of weft insertion, and the weight of the

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] Depend on Figure 1-2 It can be seen that a weft insertion system for an air-jet loom includes a special-shaped reed 8, a fixed-length weft feeder 3, a main nozzle, an auxiliary nozzle 9, a weft detector and scissors 7, and the special-shaped reed 8 is provided with a reed groove 14, and the reed groove 14 A number of auxiliary nozzles 9 are provided in the notch of the special-shaped reed 9, and a weft detector is arranged at one end of the special-shaped reed 8 adjacent to the auxiliary nozzles 9. The other end of the special-shaped reed 8 is provided with a main nozzle, and scissors are arranged between the main nozzle and the special-shaped reed 8 7. The weft yarn 2 withdrawn from the bobbin 1 is connected to the main nozzle through the fixed-length weft feeder 3 and the yarn guide 4. The main nozzle includes a fixed main nozzle 5 and a swinging main nozzle...

Abstract

The invention relates to a weft insertion system for an air-jet loom, comprising a special-shaped reed, a fixed-length weft feeder, a main nozzle, an auxiliary nozzle, a weft detector and scissors. Auxiliary nozzle, adjacent to the auxiliary nozzle, a weft detector is provided at one end of the profiled reed, and a main nozzle is provided at the other end of the profiled reed. The long feeder and yarn guide are connected to the main nozzle. The invention is simple in structure and reasonable in design. While ensuring the efficiency of weft insertion, the accuracy of weft insertion coordinates is improved, and at the same time, the tension of the weft yarn before it enters the swinging main nozzle is reduced, and the weft yarn is prevented from entering the trap after passing through a long shed. Accidents that cause weft detachment during the weft device.

Description

technical field [0001] The invention relates to a weft insertion system for an air-jet loom, belonging to the technical field of air-jet loom textiles. Background technique [0002] The air-jet loom is a shuttleless loom that uses jet air to pull the weft yarn through the shed. Its working principle is to use air as the weft insertion medium, and use the compressed air jet to generate frictional traction on the weft yarn to pull the weft yarn through the shed. The purpose of weft insertion is achieved by the jet generated by the air jet. This weft insertion method can enable the loom to achieve high speed and high production. Among several shuttleless looms, the air-jet loom is the one with the highest speed. Due to the reasonable weft insertion method, high weft insertion rate, easy and safe operation, wide variety adaptability, low machine material consumption and high efficiency , high speed, low noise and other advantages, it has become one of the most promising new clo...
