The invention relates to a multiaxial warp knitting machine. The multiaxial warp knitting machine comprises a machine frame, a warp yarn unwinding mechanism, a weft yarn unwinding mechanism, a weft yarn laying device, a knitting mechanism for knitting yarns, a cutting device and a winding mechanism. The weft yarn unwinding mechanism comprises a yarn arranging mechanism arranged on the machine frame. The yarn arranging mechanism comprises a yarn guide frame arranged on the machine frame. A swinging frame for performing reciprocating swinging relative to the yarn guide frame is arranged on the yarn guide frame. At least two yarn guide rollers arranged in a spaced mode are arranged in the yarn guide frame. Yarn guide rods with the number corresponding to the number of the yarn guide rollers and yarn penetrating plates assembled on the swinging frame and provided with yarn penetrating holes are arranged in the swinging frame. By means of the multiaxial warp knitting machine, the problem that in the prior art, as the width of yarn guide rollers needs to be increased, the tension of laid weft yarns is not coincident can be solved, it is finally guaranteed that the knitting process is smoothly carried out, the knitting efficiency is improved, and the product knitting quality can also be guaranteed.
