Abstract

The invention discloses an electric-hydraulic proportional opening device for an air jet loom. The electric-hydraulic proportional opening device for the air jet loom comprises multiple harness frames arranged in parallel, wherein the lower part of each of the harness frames is connected with a lifting driving connecting rod through a connecting rod; the lifting driving connecting rod is connected with a servo cylinder through the connecting rod; the servo cylinder is connected with a proportional servo valve through an oil path; and the proportional servo valve, a power amplifier device and a computer are connected in turn through a circuit. The invention also relates to a control method for the opening device. According to the invention, the adjustment for all the opening parameters is realized by changing preset program parameters by software, the weaving cost is lowered and the labor productivity is increased.

Description

technical field [0001] The invention belongs to the technical field of textile machinery and equipment, and in particular relates to an electro-hydraulic proportional opening device suitable for an air-jet loom, and also relates to a control method for the above-mentioned opening device. Background technique [0002] The electro-hydraulic proportional shedding technology is an advanced shedding technology suitable for air-jet looms. It applies the control signal generated by the computer to the proportional servo valve, and then controls the servo cylinder to make the heald frame move up and down according to a certain rule. The new technology of automatic shedding can greatly improve the performance of the air-jet loom. [0003] The traditional opening structure of the air-jet loom is a crank opening mechanism. The air-jet loom opening mechanism invented by Jiangsu Wangong (patent number: ZL200910186484) includes a left crank, a left connecting rod, a right crank, a right c...
