Description
Technical Field
The utility model relates to a spinning machine, it relates to a rapier weaving machine is weaving the sparse fabric's that is evenly sensitive to the eye and prevents grade fault application device specifically to say so.
Background
The reed is fixed on the sley of the rapier loom in the prior art, warp yarns penetrate between the reed dents, and the warp yarns are moved up and down by the heald frame to form a shed by upper-layer warp yarns and lower-layer warp yarns. The sley swings back and forth, when the sley is far away from the cloth fell, weft yarns are introduced into a shed formed by upper-layer warp yarns and lower-layer warp yarns, the reed pushes the weft yarns in the cloth fell to beat to the cloth fell in the process that the sley moves towards the cloth fell, and meanwhile, the upper-layer warp yarns move down and the lower-layer warp yarns move upwards to be interlaced to finish one-time interlacing, so that the warp yarns and the weft yarns are interlaced to form cloth at the cloth fell. The weaving machine take-up roller leads the woven cloth away from the weaving opening. The region from the weft just beaten to the fell to the weft which does not move relatively due to beating-up relation and affects the buckling change of the warp and weft is called a fabric forming region. The stabilization of the fabric structure does not end after one beat-up, but the relative movement of weft and warp threads still takes place in the fabric forming zone at a distance from the weaving shed. The weft yarns in the fabric forming area have not yet obtained a definite fabric structure. The cloth supporting table of the rapier loom plays a key role in stabilizing the position of a cloth fell, and the minimum interval size between the front cloth supporting edge of the cloth supporting table of the rapier loom and a reed is 2 mm. When the common fabric with high density and compact fabric structure is woven, the stability of the cloth fell can be well ensured, and the fabric structure can not be influenced.
The rapier loom weaves sparse fabric which is uniformly sensitive to the eyelets, the eyelet range is 10-30 meshes, the surface of the fabric yarn is smooth, the woven eyelet structure is unstable before shaping, and the woven eyelet structure can deform when being scraped by an external object, so that the basic requirement of uniform eyelets can not be met.
In the process of normally weaving the sparse fabric which is uniformly sensitive to the holes, the woven cloth passes through the front cloth supporting edge of the cloth supporting platform in one continuous direction, and the hole structure of the cloth is kept stable. However, if warp and weft break occur, the loom has an automatic motion of cloth fell compensation, the loom can move forwards and backwards at a slow speed, the cloth cover automatically moves back and forth, and when the minimum gap between the front cloth supporting edge of the cloth supporting table of the loom and the reed is 2 mm, the front cloth supporting edge of the cloth supporting table can stir the weft yarns in the fabric forming area at the cloth fell back and forth. The minimum clearance between the front cloth supporting edge of the loom cloth supporting table and the reed is 2 mm, and the several unstable wefts at the cloth fell are shifted away from the normal position by the front cloth supporting edge of the loom cloth supporting table, so that the fabric structure is damaged, and the uniformity of cloth cover holes is influenced. Meanwhile, the weaving machine rolls up that the route leading the woven cloth away from the weaving opening forms an included angle of about 13 degrees with the horizontal line, a cloth cover forms a larger fold line at the front cloth supporting edge of the cloth supporting table, the shifting strength of the front cloth supporting edge of the cloth supporting table to weft yarns is increased, the weft yarns are shifted away from the normal position, and the cloth cover can form a defect after the weaving machine is driven. Therefore, the applicable range of the rapier loom is limited by the size that the gap between the front cloth supporting edge of the cloth supporting platform of the rapier loom and the reed is 2 mm.
