Problems solved by technology

Therefore, the air-jet loom must use a large jet power for air-jet weft insertion or use a component that restricts the airflow to prevent the diffusion of the airflow. , but unclosed notches still diffuse the airflow and even cause the weft to deviate

Abstract

The invention provides a fully-closed pipeline sheet of an air jet loom, which comprises a pipeline sheet, wherein the pipeline sheet comprises an arc flaky supporting rod; two ends of the flaky supporting rod are fixed between an upper cross beam and a lower cross beam; an upper elastic sheet and a lower elastic sheet are arranged at the two ends of the flaky supporting rod respectively; magnets are arranged at the other ends of the upper elastic sheet and the lower elastic sheet, and are contacted on one side of the middle of the flaky supporting rod; a first arc elastic sheet and a second arc elastic sheet for being propped against the upper elastic sheet and the lower elastic sheet respectively are arranged in the middle of the flaky supporting rod; arc openings of the first arc elastic sheet and the second arc elastic sheet are opposite; warps passing through the pipeline sheet are interweaved to form a shed; magnetic guide rollers with the same magnetic poles as the magnets are arranged on the upper side and the lower side of the shed respectively. According to the invention, an open weft passage on the traditional pipeline sheet can be closed by the upper elastic sheet and the lower elastic sheet to enable airflow inside the weft passage to be less prone to diffusing, so that the picking is further and more precise.

Description

technical field [0001] The invention relates to the field of shuttleless looms, in particular to a fully enclosed duct piece of an air-jet loom that reduces airflow diffusion. Background technique [0002] The air-jet loom is a shuttleless loom that uses jet air to pull the weft through the shed. The working principle is to use the air as the weft insertion medium, and use the compressed air jet to generate friction and traction on the weft yarn to pull the weft yarn through the shed, and achieve the purpose of weft insertion through the jet generated by the air jet. This weft insertion method enables 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 ...
