Warp constant tension device for ribbon loom

Abstract

A warp constant tension device for a ribbon loom comprises a frame, a warp beam rotatably arranged on the frame, a tension stand, a regulating mechanism and two tension ropes arranged symmetrically, wherein the warp beam comprises two disks with the circumferential side provided with grooves, the two disks are fixedly connected through a winding post, the two tension ropes wind the upper ends and the lower ends of the left side and the right side of the tension stand respectively to be wound in the grooves of the two disks; the regulating mechanism can be arranged on the tension stand in a vertically movable mode; a plurality of warps are wound on the winding post; and the plurality of warps are pulled above the regulating mechanism and butted against the upper side of the regulating mechanism and then pulled to the ribbon boom. The warp constant tension device for the ribbon loom can guarantee tension balance at both ends of the warp beam, and achieve constant tension of warps of the warp beam, thus stabilizing quality of woven fabric ribbons. In addition, positions of supporting points of warps can be changed under the vertical action of the regulating mechanism; therefore fine adjustment of constant tension of warps can be achieved. Compared with the prior art, the accuracy is remarkably increased.

Description

technical field [0001] The invention relates to a device used in conjunction with a ribbon loom, in particular to a warp constant tension device of the ribbon loom. Background technique [0002] Ribbon looms include nylon looms, metal looms and resin looms. Their main function is to weave warp, weft or center lines together to form unreinforced zipper tapes or ribbed zipper tapes. The rib is the centerline. [0003] At present, the tension device of nylon and metal looms is to adjust the tension through a single-sided weight counterweight with a screw, and use nylon thread or rope to bear the weight, so that it may be affected by external factors, and the constant tension at both ends of the warp head cannot be achieved. Just can't realize warp thread constant tension fine-tuning, will cause the unstable quality of braided cloth belt.
