Benefits of technology

This new design allows for faster movement than previous versions without damaging any part or causing unwanted noise from their components during operation.

Problems solved by technology

This patented describes an improvement in current air jet looms that uses cam shuttling systems instead of traditional methods like hydraulic lift or wire rope hoist machines. However, these improvements have limitations due to factors such as precise machining required during production, difficulty in achieving very accurate movements at speeds above 1900rpm, poor response time caused by friction between moving parts, and potential issues related to stress on certain critical components (such as bearings).

Abstract

The invention discloses a flat opening mechanism with a moving pair; the flat opening mechanism comprises a connecting rod mechanism with the moving pair as well as a pushing rod and swinging rod mechanism, wherein the pushing rod and swinging rod mechanism comprises a pull rod; two ends of the pull rod are respectively hinged with a first swinging rod and a second swinging rod; the first swinging rod and the second swinging rod are respectively hinged with a third swinging rod and a fourth swinging rod; the third swinging rod and the fourth swinging rod are respectively hinged with a first connecting rod and a second connecting rod; the first connecting rod and the second connecting rod are both hinged with a heald frame; and the pushing rod and swinging rod mechanism is connected with the connecting rod mechanism with the moving pair by the pull rod. According to the invention, in order to adapt to high rotation speed of 900-1000 rpm of the traditional air jet loom, the flat opening mechanism with the moving pair is designed from an angle of high speed of the loom; a cam opening mechanism is replaced with the connecting rod mechanism with the moving pair, so that the damages of other parts of the air jet loom are avoided when vibration sources such as a cam and a cam rotor are eliminated.
