The specific embodiment

The present invention adopts general machine design method design, and main body is frame, mainly contains on the frame to comprise four great institutions: spooler, shedding mechanism, weft insertion device, warp-feeding mechanism.

As shown in Figure 1 and Figure 2, two groups are batched guide rail 2 is fixed on frame 1 front end along X-direction by screw for groove shapes both sides, yarn-fixing plate 3 and yarn dividing plate 4 all are comprised of four long thin bars, yarn-fixing plate and yarn dividing plate are fixed on along Z-direction by nut and batch on the plate 16, batch integrated circuit board and in batching guide rail groove, rely on rack-and-pinion to carry out transmission, it can be moved around batching guide rail.Yarn-fixing plate is fixing X-direction warp thread, is the main source of curling pulling force, and yarn dividing plate is dividing sinker mechanism, guarantees the level of yarn.When yarn passes through yarn dividing plate, utilize the wide thin bar of layer to divide and be laminated into yarn dividing plate, guaranteed globality and the level of yarn, the X-direction yarn is concentrated and is pressed on the yarn-fixing plate, here not having the level requirement, mainly is the main source of curling pulling force, also makes things convenient for the transfer of woven fabric.When woven fabric reaches certain-length, can pack into endways and batch plate, cut off the X-direction yarn, woven fabric just can conveniently break away from loom.

Such as Fig. 1, Fig. 2, Fig. 4 and shown in Figure 5, radially reed 5 is the long thin bars with dent, radially reed by two-way nut compress be fixed on radially reed plate 6 along Y-direction on, radially the reed integrated circuit board is in Y-direction opening guide rail 17 grooves, radially the reed plate can move in Y-direction opening guide rail groove.Wefting insertion pin 7 is in the middle of the radially reed plate of two subtends, and wefting insertion cushion is on the wefting insertion frame, and the wefting insertion frame is stuck in the Z-direction wefting insertion guide rail 19, can move up and down at its guide rail, and wefting insertion frame upper end is hung on the harness lever by thin wire, and it moves up and down by programme-control.After two radially the reed plate stretched into, dent can accurately block every one thread, made yarn form rubbing, had so just formed opening, and the wefting insertion needle mould is intended the form of Sewing needles and introduced with the yarn Z-direction, had just finished opening and the action of Z-direction wefting insertion of Y-direction.

Many heald frames 9 pass through the thin wire connecting hanging on harness lever 10, control its motion by harness lever, many heald frame lower ends are connected to the frame bottom by spring, play the effect of tension return, arrow shaft is mobile at the tooth bar of arrow shaft frame 8 along Z-direction by gear driven, and the arrow shaft frame again can be along moving on the Y-direction wefting insertion guide rail.Adjacent X-direction yarn passes adjacent heald frame, the relative motion of adjacent heald frame just makes yarn form opening in Y-direction, single arrow shaft is fixed on the wefting insertion bar, can be mobile at the wefting insertion bar, the wefting insertion bar is fixed on the rack rail and can moves along Y-direction, and the Z-direction motion on the wefting insertion bar of the Y-direction motion of wefting insertion bar and arrow shaft combines and finishes the work of Y-direction wefting insertion.

Such as Fig. 1, Fig. 2 and shown in Figure 3, warp let-off frame 13 is fixed on the frame end, warp let-off frame is fixed with many (X) root warp beam 14 by bearing from top to bottom, connect with gear between the every warp beam, adjacent two warp beam counter motions, i.e. the reverse warp let-off of adjacent warp beam, spreader 11 is fixed on the frame by screw along Y-direction, vertically arrange a lot of thin bars in the spreader, the yarn of can the combing warp-feeding mechanism sending.The n row warp of sending carries out the dividing sinker arrangement at spreader, and the assurance yarn can fitly be sent into shedding mechanism and weft insertion device by level.

The present invention adopts through-drive, and the machine running part has motor, decelerator, bevel gear and power transmission shaft 15.By motor-driven, motor and turbine and worm decelerator are fixed on the frame bottom by screw, connect by belt, friction plate is installed in decelerator low speed end and realizes intermittently control, friction plate is connected with power transmission shaft by angular wheel 18, power transmission shaft is to be fixed on the frame side with bearing, and each between centers also adopts bevel gear to connect.

The running of yarn: as shown in Figure 1, warp-feeding mechanism is sent, and process Z-direction shedding mechanism, Y-direction weft insertion device, Y-direction shedding mechanism, Z-direction weft insertion device are to spooler successively.

M row X-direction yarn 12 is by the warp let-off of m/2 root warp beam; Y-direction is by many heald frame openings, and n arranges rapier weft inserting, and Z-direction is by warp-wise reed opening, and n arranges wefting insertion pin band Z-direction yarn wefting insertion; Because the laxity of three-dimensional woven fabric need not beating device; Batch with warp-feeding mechanism synchronously, because it can not volume property, adopt and batch dolly and batch.
