Detection device of air jet loom weft insertion system

Abstract

A detection device of an air jet loom weft insertion system is characterized in that a pressure meter is arranged in an air flow hole in the top face of a base block, the lower end of the air flow hole is connected with a detection head which is arranged in a screw hole in the lower end of the left side of the base block, the detection head is fixed into the screw hole of the front side of the left lower end of the base block, and the front end of the detection head is flush with the bottom face of the base block; one end of a ranging rod is fixed to the bottom end face of the left side of the base block in a riveting mode, and the ranging rod is located behind the detection head; a positioning plate with a boss is arranged at and fastened to the upper end of the back face of the base block through bolts and nuts, and a groove is formed between the boss on the positioning block and the base block; the upper end of a special-shaped steel buckle is inserted into the groove formed between the boss on the positioning plate and the base block, and the lower end of the special-shaped steel buckle is inserted into a groove in an auxiliary spraying nozzle base; the detection head is inserted into a buckling groove in the special-shaped steel buckle, an auxiliary spraying nozzle is arranged on the auxiliary spraying nozzle base, the upper end of the auxiliary spraying nozzle makes contact with the groove in the bottom of the base block, and the lower end of the spraying nozzle is connected with one end of a gas delivery pipe.

Description

technical field [0001] The invention relates to a detection device for an air-jet loom, in particular to an on-line detection device for the weft insertion system of the air-jet loom. Background technique [0002] When air-jet loom weft insertion, when the main nozzle airflow and auxiliary nozzle airflow meet the air flow in the shaped reed reed groove, a bundle of synthetic airflow that meets the requirements of the weft insertion process is formed, and the weft yarn advances along the reed groove with the airflow; due to the manufacturing process It is complex and more difficult to manufacture than other reeds for shuttleless looms and shuttle looms. Reed sheet manufacturing and airflow adjustment testing are the key and difficult points of the entire production process. The current problems in the use of air-jet looms are: regardless of whether imported looms or domestic air-jet looms are used for a long time and the operating level of equipment maintenance personnel is d...

AI Technical Summary

Problems solved by technology

The current problems in the use of air-jet looms are: no matter whether imported looms or domestic air-jet looms are used for a long time and the operating level of equipment maintenance personnel is different, the most critical weft insertion system of air-jet looms varies with the production unit and is in good condition. It is also different, often the inspection only qualitatively judges whether it is good or bad, and cannot quantitatively check the status of the relay weft insertion of the auxiliary nozzle in the profiled reed.
