Problems solved by technology

The reed and the air channel of the pipe piece air-jet loom are separated, the cost is low, and it is easy to replace; but because there is no relay weft insertion, it cannot meet the requirements of weaving wide fabrics
The advantage of the special-shaped reed type air-jet loom is that it can realize the wide-width weaving of fabrics, but its disadvantages are: its airflow channel is U-shaped semi-closed, the airflow leakage is more serious, and the air consumption is large, and the special-shaped reed and the airflow channel are integrated, and the shape Complex, high cost, difficult to adapt to the requirements of frequent replacement of fabric varieties

Abstract

An electromagnetic-pneumatic combination weft insertion mechanism comprises a main jet weft-inserting device, a weft cut-off device, an airflow passage component, a weft detection sensor, a microprocessor and an auxiliary nozzle. The airflow passage component is composed of extensible electromagnetic-pneumatic integrated weft-inserters; one side of each extensible electromagnetic-pneumatic integrated weft-inserter is provided with an electromagnetic coil, while an electromagnetic disc composed of an extensible electromagnetic disc plastic layer and an electromagnetic disc magnet layer is pasted to the other side; the length of a required weft insertion passageway is determined flexibly according to fabric breadth. During operating processes, when detecting a weft, the weft detection sensornear a main nozzle provides feedback to the microprocessor; the microprocessor controls positive and reverse connections of electromagnetic coil circuits on the weft-inserters so that the adjacent weft-inserter electromagnetic discs perform sucking or rebounding under the action of an electromagnetic field, and a weft insertion passage is closed and reset. A novel weft insertion mode having a nearly-enclosed flight cavity is provided herein; the whole weft insertion process is more efficient and more energy efficient at the premise of weaving broad cloths.

Description

technical field [0001] The invention relates to a new type of weaving equipment for weaving fabrics in a textile factory, in particular to an electromagnetic gas composite weft insertion mechanism used on an air jet loom. Background technique [0002] The current mainstream air-jet looms can be divided into two categories according to the difference in air flow channels: pipe-type air-jet looms and special-shaped reed-type air-jet looms. At present, the existing pipeline piece air-jet looms at home and abroad all adopt the weft insertion method of main nozzle + pipeline piece air channel, and the special-shaped reed air-jet loom mainly adopts the relay weft insertion method of main nozzle + auxiliary nozzle + special-shaped reed. The reed and the air flow channel of the pipe piece air-jet loom are separated, the cost is low, and it is easy to replace; but because there is no relay weft insertion, it cannot meet the requirements of weaving wide fabrics. The advantage of the ...
