10. use wide cut carbon fiber knit machine to produce a method for carbon fiber mesh fabric, comprise the steps, it is characterized in that:
Steps A: a kind of method of using wide cut carbon fiber knit machine to produce carbon fiber mesh fabric, the paper of taking in of release paper roll is placed on braiding platform, and Scroll is sent into in the one end of taking in paper, by organizing the carbon fiber wire band expanding after fibre, be placed on warp thread creel more, by expanding carbon fiber wire band after fibre, by drawing transmission shaft, penetrate respectively and on warp thread pulling apparatus, lift the sending in yarn hole of tooth, be placed in taking on paper on braiding platform, one group of carbon fiber wire band expanding after fibre is placed on weft yarn creel, by expand carbon fiber wire band after fibre penetrate put on yarn feeding device several directive wheels between, be placed in the weft yarn holder of Weft cutting-off apparatus, and lean out 3-5cm,
Step B: electric cabinet control to start braiding machine, and two one of pulling apparatus move upward, and one moves downward, is often separated by one and separates up and down organize the carbon fiber wire band expanding after fibre more;
Step C: weft yarn draw-gear starts, by servomotor, drive the drive link on transmission slide rail to move to Weft cutting-off apparatus direction, the finger cylinder inductor of drive link front end receives signal, gripping finger is opened, behind carbon fiber wire band position after the expansion fibre of the 3-5cm that the gripping finger motion of drive link front end to weft yarn holder leans out, point cylinder inductor and receive signal, gripping finger is closed, and the carbon fiber wire band after expansion fibre is stung and strained at the other end of dragging back braiding platform;
Step D: the weft yarn translating device of braiding platform both sides starts, the finger cylinder inductor of weft yarn translating device receives signal, gripping finger is opened, by translation drive unit driving mechanical arm, move forward, the gripping finger of weft yarn translating device is moved to the carbon fiber wire band position after the expansion fibre pulling go back to, finger cylinder inductor receives signal, gripping finger is closed clamps the carbon fibre tow band expanding after fibre, cylinder inductor receives signal, Weft cutting-off apparatus starts, and by filament cutting mechanism, the carbon fiber wire band expanding after fibre is cut off;
Step e: stepping sensor receives signal, weft yarn is put yarn feeding device and is started, stepper motor drives directive wheel to rotate the carbon fiber wire band expanding after fibre is sent to weft yarn holder, and stop after leaning out 3-5cm, simultaneously, the finger cylinder inductor of weft yarn draw-gear receives signal, gripping finger is opened, after the translation drive unit driving mechanical arm of weft yarn translating device, move, weft yarn is drawn in to braiding platform, the finger cylinder inductor of weft yarn translating device receives signal, gripping finger is opened, the mechanical arm of weft yarn translating device moves after continuing with the carbon fiber wire band expanding after fibre throws off,
Step F: Scroll rotates a distance that expands the carbon fibre tow bandwidth after fibre, completes weft yarn braiding process one time;
According to A, B, C, D, E, the reciprocating motion of F process mechanism, can realize the automation braiding of expanding the carbon fiber wire band grid cloth after fibre.
