Abstract

The invention discloses a positive type adjustable tension yarn feeding device and a work method thereof. The device comprises a yarn disc, a clockwork spring mechanism, a direct current motor gear pair mechanism, a ratchet mechanism and the like. The clockwork spring mechanism is used for adjusting the yarn feeding tension, and yarn disc yarn recycling or conveying out is achieved through the direct current motor gear pair mechanism. The ratchet mechanism is matched with the yarn disc to move in a forward rotation or reverse rotation manner. A contactor on the outer side of the clockwork spring mechanism makes contact with a first contact point or a second contact point of the inner side of the yarn disc, accordingly, forward rotation or reverse rotation of a direct current motor is judged, and accordingly the problems about yarn feeding tension adjustment and yarn tension fluctuation in the yarn feeding process are solved. According to the work method, the yarn feeding tension is adjusted at random within a certain range, the requirement for tension adjustment in the weaving machine running process is met, and uneven fabric linings due to tension fluctuation are avoided.

Description

technical field [0001] The invention relates to the textile industry, in particular to a positive adjustable tension yarn feeding device and a working method thereof. Background technique [0002] With the continuous development of modern industry, the textile industry has developed rapidly, especially textile materials woven from high-performance fibers have been widely used in aerospace, automobiles, ships and other fields. And this high-performance fiber generally cannot adopt the warp beam of whole let-off roller type to complete the warp let-off action, and generally adopts creel form to satisfy the requirement of warp yarn beam feeding separately. Due to the variety of high-performance yarns and the different properties of fiber materials, especially because of the variety of fabric structures, it is often necessary to adjust the yarn tension to meet different weaving needs. In addition, due to opening, beating-up and other actions during the weaving process will caus...
