Problems solved by technology

[0003] In order to overcome the defect that the existing pipe piece air-jet loom cannot meet the requirements of fabric wide weaving, the present invention provides an integral pipe piece and relay auxiliary nozzle, so that the original "main nozzle + pipe piece airflow channel" The weft insertion method has also been changed to the relay weft insertion method of "main nozzle + auxiliary nozzle + pipe sheet airflow channel" to meet the requirements of fabric wide weaving

Embodiment Construction

[0008] Such as image 3 As shown, an integral duct piece relay auxiliary nozzle and an integral duct piece together form an air flow channel unit, the length of which is L. In each air flow channel unit, the center of the injection hole of the integral duct sheet relay auxiliary nozzle is concentric and at the same angle as the center of the conical groove on the integral duct sheet, and the auxiliary jet flow ejected from the auxiliary nozzle injection hole, Guided by the conical grooves on the integral pipe piece, it enters the main jet flow channel of the pipe piece and meets the main jet flow to form a relay weft insertion airflow. Both the relay auxiliary nozzle of the integral duct piece and the integral duct piece are formed by one-time pressing with a mold, and the concentricity between each airflow channel unit is guaranteed by positioning pins.

[0009] The number of the air channel units depends on the width of the fabric, and several air channel units are closely ...

Abstract

The invention relates to an integral conduit sheet type relay assistant nozzle for a jet loom, which consists of an integral conduit sheet type relay assistant nozzle, an integral conduit sheet provided with a conical air guide groove, and an air inlet pipe joint. The integral conduit sheet type relay assistant nozzle for the jet loom can change the prior weft insertion means of 'a main nozzle and a conduit sheet type air channel' into the relay weft insertion means of 'a main nozzle, an auxiliary nozzle and a conduit sheet type air channel', so as to meet the demand of weaving wide textile fabrics.

Description

Technical field [0001] The invention relates to an integral pipe piece and a relay auxiliary nozzle used on an air-jet loom, belonging to a new type of weaving equipment for weaving fabrics in textile mills. technical background [0002] Air-jet looms can be divided into two categories according to their air flow channels: pipe-type air-jet looms and special-shaped reed-type air-jet looms. At present, the existing pipe-type air-jet looms at home and abroad all adopt the weft insertion method of "main nozzle + pipe-type air flow channel", while the special-shaped reed air-jet looms all use "main nozzle + auxiliary nozzle + special-shaped Reed-type airflow channel" relay weft insertion method. The advantage of the relay weft insertion method of the special-shaped reed air-jet loom is that it is suitable for wide-width weaving of fabrics. The disadvantages are: ①Because the airflow channel is "U"-shaped and semi-closed, the airflow leakage is serious and the air consumption is...
