Wrap loosening device for air jet loom

Abstract

A warp loosening device for an air jet loom comprises an air jet loom frame (1), an air jet loom warp loosing shaft (2), a crank (3) is hinged on the air jet loom warp loosening shaft (2), a warp loosening rod (4) is hinged on the crank (3), the air jet loom frame (1) is fixedly provided with a support (5), the support (5) is fixedly provided with a guide block (6), the warp loosening rod (4) is sleeved outside the guide block (6) through insertion, one end of a pressure spring (7) acts on the warp loosening rod (4), and the other end of the pressure spring (7) acts on the guide block (6). Under the condition that the rotating speed of the loom is not high, the warp loosening device for the air jet loom enables the back rest roller inertia to be in a controllable range, enables the warp to be synchronous with the opening of the loom all the time and keep balanced tension, is clear in opening, and facilitates the weaving of multicolour different fiber yarn on the loom.

Description

Technical field: [0001] The invention relates to the technical field of solar energy, in particular to an easing device of an air-jet loom. Background technique: [0002] In the past, air-jet looms all adopted positive warp easing, and the positive warp easing device is that a rocker arm is hinged on the warp easing shaft of the air-jet loom, and the warp easing shaft of the air-jet loom is loosened by the swing force of the rocker arm. Its weak point is: the positive loose warp mode is suitable for the loom high-speed weaving of more than 500 revs / min of rotating speed, but is not suitable for the ultra-wide air-jet loom below 500 revs / min. Because, in the actual use of positive warp loosening, the cooperation with the shedding amount and shedding time of the loom cannot be closely unified, and there are large errors, which may easily cause additional shedding defects and warp damage. Invention content: [0003] The purpose of the present invention is to address the defi...

AI Technical Summary

Problems solved by technology

Its disadvantages are: the positive loose warp method is suitable for high-speed weaving of looms with a speed of more than 500 rpm, but it is not suitable for ultra-wide air-jet looms with a speed of less than 500 rpm

Because, in the actual use of positive warp easing, the cooperation with the shedding amount and shedding time of the loom cannot be closely unified, and there is a large error, which may easily cause additional shedding failure and warp damage
