Abstract

The invention discloses a protection device for a high-pressure air guiding pipe. The protection device for the high-pressure air guiding pipe comprises an upper clamping head and a lower clamping head, wherein the upper clamping head and the lower clamping head are fastened through a screw nail assembly; the upper clamping head is provided with a first opening through which the screw nail assembly passes, an upper bearing channel for clamping the high-pressure air guiding pipe and an upper buffer groove; the lower clamping head comprises an installation base, a lower bearing channel for clamping the high-pressure air guiding pipe and a lower buffer groove; and a second opening is arranged on the installation base. The upper bearing channel, the upper buffer groove, the lower bearing channel and the lower buffer groove are made of elastic rubber. According to the protection device for the high-pressure air guiding pipe, disclosed by the invention, the upper buffer groove and the lower buffer groove are made of the elastic rubber, so that harmful vibration brought to the air guiding pipe from a pulse high-pressure airflow can be largely reduced.

Description

Technical field [0001] The invention relates to a textile equipment, more specifically, a high-pressure air duct protection device for an air jet loom. Background technique [0002] The air-jet loom is a shuttleless loom that uses jet airflow to pull the weft through the shed. The working principle is to use air as the weft insertion medium. The compressed airflow is used to generate frictional traction on the weft yarn to draw the weft yarn through the shed. The jet generated by the air jet achieves the purpose of weft insertion. In the process of jetting high-speed airflow from the high-speed jet tube of the existing air-jet loom, the high-pressure airflow is delivered from the air pump to the jet nozzle through the air guide tube, and the air guide tube is usually simply fixed with nylon buckles, which is extremely prone to shaking. [0003] Chinese invention patent ZL200920290328.6 discloses an air supply system for the main nozzle of a multi-weft air-jet loom, which includes ...
