Description

Technical Field

[0001] The utility model relates to a beating-up special-shaped reed for an air jet loom, belonging to the technical field of special-shaped reeds. Background Art

[0002] The profiled reed is an important part of the air jet loom. In actual production, due to the operation of guiding the weft yarn, the reed groove of the profiled reed will inevitably wear out. If the profiled reed is damaged to a certain extent, it will affect the safety performance of the profiled reed and easily cause the air jet loom to fail to operate normally. At present, the advanced air jet looms used in China all use profiled reeds. Profiled reeds are important consumables for weaving high-end, high-quality, and high-value-added refurbished weaving fancy varieties. Due to the increasingly high requirements for important indicators such as the structure, processing accuracy, precise size and parallelism of the profiled reed, and the uniformity of the reed teeth, the standards must be further improved. The profiled reed has been transformed from ordinary type to high-end dense type.

[0003] In the prior art, for example, the Chinese patent number CN105177841B, "A special-shaped reed for an air jet loom and an air jet loom", comprises a plurality of reed blades arranged side by side, each of which has a guide recess, an upper jaw and a lower jaw; the front end of the upper jaw has an upper jaw arc surface formed with a curvature radius R2, the front end of the lower jaw has an upper jaw arc surface formed with a curvature radius R3, the guide recess has an inner arc formed with a curvature radius R1 The upper jaw arc surface, the inner arc surface and the lower jaw arc surface are connected in sequence, and the distance between the upper jaw arc surface and the lower jaw arc surface is less than twice R1; the upper jaw portion extends forward by a distance L1 between its front end portion and the vertical tangent of the inner arc surface, and the lower jaw portion extends forward by a distance L2 between its front end portion and the vertical tangent of the inner arc surface, L1≤2(R1+R2)≤8mm, L2≤2(R1+R3)≤6mm, L1>L2>0.5L1. The beneficial effect is that the special-shaped reed has low air consumption and high weft insertion efficiency.

[0004] However, in the prior art, the yarn is beaten with a profiled reed. Due to the weight of the weft yarn itself, long-term beating will cause inconsistent tension in the middle and ends of the weft yarn, resulting in uneven tightness of the weft yarn, affecting the quality of textile weaving. The profiled reed needs to be tightened to improve its flatness level. Utility Model Content
