Special ejector for picanol air jet loom

Abstract

The invention belongs to the field of dust removal or demisting equipment, and relates to a special ejector for a picanol air jet loom. The ejector comprises an ejector body; a weft insertion channelis arranged in the middle of the ejector body in the axial direction, one end of the weft insertion channel is provided with a yarn inlet, the other end of the weft insertion channel is provided witha yarn outlet, a ceramic ring is arranged in the weft insertion channel at one end of the yarn inlet, a middle through hole is formed in the ceramic ring, and the outer wall of the ceramic ring and the wall of the weft insertion channel are fixed; and the end part of the ejector body at one end of the yarn outlet is provided with an annular sawtooth nozzle, the annular sawtooth nozzle comprises aplurality of sawteeth which are uniformly arranged in the circumferential direction, and the tips of the sawteeth are along the outside of the ejector body and in the axial direction of the ejector body. The ejector is reasonable in structural design; rebounded yarns can be hooked, so that the elastic yarns can be effectively prevented from being rebounded and the weft insertion effect is guaranteed; and the ceramic ring is arranged at the yarn inlet and the wear resistance of the ceramic ring is good, so that serious wear of the yarn inlet is prevented and the overall service life is prolonged.

Description

technical field [0001] The invention relates to a special injector for picanol air-jet looms, which belongs to the technical field of textile machinery. Background technique [0002] As a popular textile loom, Picanol air-jet looms are favored by textile factories and are suitable for weaving various raw material yarns. However, when weaving elastic yarn varieties, the yarn rebounds quickly. When the weft feeder switches the weft insertion, the yarn in the main nozzle rebounds, causing the weft shrinkage of the cloth surface, or blowing the yarn to break the twist, affecting the cloth surface. Quality; and the yarn inlet position is severely worn, which affects the overall service life. Contents of the invention [0003] The object of the present invention is to propose a special injector for picanol air-jet looms, the annular sawtooth nozzle of the special injector for picanol air-jet looms can hook the rebound yarn, effectively prevent the rebound of the elastic yarn, a...
