Ultrahigh-speed air jet loom

Abstract

The invention discloses an ultrahigh-speed air jet loom which adopts the host structure of a high-speed air jet loom and comprises a conventional brake disc, an air pocket without air channel and a main nozzle, wherein the air pocket without the air channel comprises an electromagnetic valve and an air pocket; the electromagnetic valve is arranged on the air pocket; the brake disc is provided with two groups of electromagnetic coils; and the main nozzle is a pressurizing main nozzle with diameter of 2.15mm and length changed into 42.15mm. In the invention, by connecting the air pocket and the electromagnetic valve, the air channel can be shortened, the air pressure is increased, and the gas waste is reduced; ultrahigh-speed braking can be effectively realized by adopting an efficient dual-coil brake disc; by adopting a thick long-range main nozzle, the weft insertion pressure and air quantity can be increased, the normal operation of the high-speed air jet loom at a speed greater than 1,000rpm can be completely realized, and an ultrahigh-speed air jet loom of which the speed under normal working conditions can reach 1,500rpm is provided; and the ultrahigh-speed air jet loom has the obvious advantages of high weaving efficiency and energy conservation.

Description

Technical field [0001] The invention belongs to the field of textile machinery, and in particular relates to an air-jet loom, in particular to an ultra-high-speed air-jet loom. technical background [0002] Ultra-high-speed air-jet loom refers to the air-jet loom whose host speed is equal to 1000 rpm in production and operation. High-speed air-jet looms usually mean that the speed of the main engine can reach 450-1000 rpm during production and operation. From the perspective of theory, experiment and test prototype, the speed of the main engine of the air-jet loom can reach more than 1000 rpm. In actual production and application, there is no air-jet loom that can reach more than 1000 rpm at present. The main reasons are: first, the braking angle of the brake disc is generally around 200°, which cannot meet the requirements of ultra-high-speed air-jet looms. , and even the problem of damage to loom parts and fabrics caused by parking; because in actual production applicatio...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that the above-mentioned high-speed air-jet loom cannot exceed 1000 rpm in actual production and operation, the present invention provides a practical production method by significantly improving the brake, air bag and main nozzle components of the high-speed air-jet loom. In operation, the speed of the main engine can completely exceed 1000 rpm to 1500 rpm.
