Abstract

The utility model provides a reed traversing mechanism, and belongs to the technical field of textiles. According to the reed traversing mechanism, guide grooves are arranged on upper and lower surfaces of the original sley for fixing a reed; small wheels which can rotate freely are arranged around the reed, and two guide rails are arranged correspondingly on a weaving machine frame additionally; and the two guide rails form an angle of 30 degrees with weft yarns and are parallel to each other. According to the reed traversing mechanism, the reed can slide freely back and forth along the guide grooves by the upper and lower small wheels; and the reed only can do reciprocating motion along the specified angles of the guide rails by the guide rails and the left and right small wheels of the reed, so that the front and back reciprocating motion and left and right traverse motion of the reed are realized, and the weaving of wide-angle cloth is feasible.

Description

The reed transversing mechanism

Technical field

The utility model relates to a kind of Loom reed transversing mechanism, and particularly a kind of Loom reed transversing mechanism that is used to weave Wide-angle cloth belongs to textile technology field.

Background technology

Wide-angle cloth is a kind of industry cloth, and it is by common woven plain cloth development.See from structure; It also is to be made up of two system's yarns; But the angle that different with the common machine fabric is between two system's yarns is not 90 ° but 120 °; This special construction makes Wide-angle cloth higher than the deformability of common machine fabric, and especially the deformability along the cloth cover vertical direction is more outstanding.

On the other hand, 120 ° angle makes it on ordinary loom, be difficult to weave between two system's yarns.Have in shuttle or the shuttleless loom what generally use at present, the formation of fabric is to rely on beating motion to accomplish.Beating motion essence is a kind of reciprocating motion: conjugate cam (adopting four connecting rods or six bar mechanism on the part loom) drives tightening weft axis and comes back rotation; Tightening weft axis drives slay move back and forth (parts that slay is promptly installed reed); Thereby make reed thereupon move reciprocatingly, that is beating motion.Through the vertical fabric of weft yarn, reed adopts fixing means to be installed on the slay for traditional, can only move back and forth, about can not traverse, thereby can't knit system Wide-angle cloth fabric.The utility model aims to provide a kind of Loom reed traversing gear, and it can make reed when beating up, accomplish and traverse about certain, thereby makes the angle of cut that warp thread and weft yarn become to need, and realizes weaving of Wide-angle cloth.

Summary of the invention

The utility model provides a kind of Loom reed transversing mechanism.

The technical scheme that the utility model adopted is: at the former chute of installation up and down that fixes the slay of reed; With about the reed, about add the steamboat that can freely rotate with different directions; And the corresponding position installs two special guide rails additional on woven frame, and these two guide rails become 30 ° and parallel to each other with weft yarn.Because the existence of steamboat makes reed to be free to slide back and forth along chute up and down; And the existence of guide rail and reed left and right sides steamboat makes the reed reciprocating motion to carry out along the angle of guide rail regulation, then the front-rear reciprocation movement of having realized reed with about traverse.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further to detail.

The described reed traversing gear of the utility model embodiment; As shown in Figure 1, comprise reed 1, be installed on left directive wheel 2-1 and right directive wheel 2-2 on the reed 1, go up left movable pulley 3-1, go up right movable pulley 3-2, left movable pulley 4-1, right movable pulley 4-2, gliding groove 6-1, upper hopper chute 6-2 down down.Being contained in the last left movable pulley 3-1 on the reed 1, last right movable pulley 3-2, following left movable pulley 4-1 and following right movable pulley 4-2 makes reed 1 being free to slide among chute 6-1 and the 6-2 up and down.During loom work, conjugate cam 7 drives tightening weft axis 8 and moves back and forth, and makes reed 1 move reciprocatingly.But this reciprocating motion is because the existence of left and right rail 5-1 and 5-2, oblique the carrying out of route that can only confirm along guide rail, promptly when reed forwards moves, the reed while in chute to left movement; Otherwise retreating then, reed traverses to the right along chute.

During practical implementation; Guide rail 5-1,5-2 adopt the special construction like Fig. 2: guide rail can be similar to regard as by two taggers and be welded; During making tagger one end in top is cut into 30 ° of angles and welds with the below tagger is vertical, perforate above the tagger of below is conveniently to use bolt.In addition, during reed 1 reciprocating motion, the side sees and is actually that to do with axle 8 be the circular motion in the center of circle, thereby the bending that arches upward in the middle of also being processed into according to this movement locus of guide rail top tagger.Fabrication and installation method such as Fig. 3 of each steamboat on the reed 1: the reed top is gone up left movable pulley 3-1 and is flat, and promptly install sidewards on the parallel and dent plane of its turning cylinder, goes up right movable pulley 3-2 roughly the same.Reed below left movable pulley 4-1 down also is flat, and its turning cylinder is perpendicular to the dent plane, promptly endways dress, and following right movable pulley 4-2 is roughly the same.This installation method major consideration of slide down driving wheel is the strong effect of the power of beating up to reed.Left side directive wheel 2-1 is the long tubular of axial length, and its turning cylinder is parallel to the dent plane, and right directive wheel 2-2 roughly the same.Above-mentioned directive wheel and guide rail are the critical pieces that makes that reed traverses, and the active force of the two is also stronger, so they all adopt the high-quality antifriction alloy to process.Chute 6-1 and 6-2 directly are packed on the slay, and its material adopts alloy, smooth surface, and certain thickness and intensity are arranged, the resistance that produces when resisting loom beating-up.

During work, with bolt guide rail is fixed on correspondence position on the loom front rest, the two length equals reed length, loads onto to adopt behind the reed and normally weaves knitting technology and can realize that reed traverses, and carries out weaving of Wide-angle cloth.
