At present, the weaving equipment of the carbon fiber cloth is mainly formed by taking a double-rapier loom (such as an imported multi-denier rapier loom) as a basis and adding a plurality of auxiliary components according to different structures of the carbon fiber cloth, wherein the double-rapier loom mainly comprises mechanisms of warp let-off, opening, picking, beating-up, reeling and the like, the warp let-off mechanism comprises warp beams and a creel, warp beams in weaving adopt radial unwinding, and creel warp yarns adopt axial unwinding to let off warp; the opening part is opened in a way that all warps penetrate into harness wire holes, the picking part picks up wefts by a rapier in a way that wefts fed by a weft accumulator of the loom are picked up, and the winding part winds by a cloth roller of the loom in a rotating way according to weft density.
Because the carbon fiber tows are flat wires, the high-quality carbon fiber cloth woven by the carbon fiber tows is particularly a bidirectional carbon fiber cloth, the carbon fiber flat tows are flat and smooth without broken filaments on the cloth surface, and once the flat wires of the carbon fiber cloth turn over and broken filaments appear, various technical indexes of the carbon fiber cloth material after post treatment can be greatly discounted. However, in the existing equipment and weaving method for weaving carbon fiber cloth, because carbon fiber yarns in the warp direction are axially unwound from a bobbin creel and can rotate and turn over in the weaving process, all warp yarns need to be lifted up and down through heddles to form openings for weft yarns to pass through and are subjected to severe beating through a reed, and the phenomenon that flat yarns turn over and are broken is avoided; the phenomenon that carbon fiber yarns are overlapped and turned over to form yarn is also generated when the weft-wise flat carbon fiber yarns are output from the weft accumulator, so that the quality of the woven carbon fiber cloth is seriously affected, and the technical performance of a product processed by post-treatment by taking the carbon fiber cloth as a matrix is further affected. Therefore, the improvement on the prior two-way carbon fiber cloth weaving equipment and the weaving method is a technical problem which needs to be solved in the industry.

Referring to fig. 2 and 3, the bi-directional carbon fiber cloth weaving device for flat spreading of the present embodiment mainly comprises a double rapier loom 1, a carbon fiber weft feeding mechanism 2, a bobbin cradle 3 and a tension combination roller cradle 4.
The double rapier loom 1 is a commercially available piece.

As can be seen from the foregoing, the weaving method of the tiled bidirectional carbon fiber cloth of the present embodiment adopts the tiled weaving, so that the weaving method is relatively simple, warp carbon fiber tows 51 are unwound from the carbon fiber warp bobbins 32 of the bobbin cradle 3 in the radial direction instead of in the axial direction as in the prior art, the flat carbon fiber tows cannot be turned over due to no axial rotation movement, the unwound warp carbon fiber tows 51 uniformly pass through the reed teeth of the reed 13 through the front beam of the direct weaving machine through the tension combination roller frame tension, and move forward in the movement, do not penetrate into heald holes as in the prior art, and therefore do not move up and down, so that the warp carbon fiber tows 51 cannot turn up the filaments laterally in the whole weaving process; the weft carbon fiber tows 53 are radially unwound from the carbon fiber weft bobbins 22 along the flat direction and are wound by the directional fixed-length disc 23 which actively rotates and has fixed length and then clamped by the lower rapier 15 of the double rapier loom 1, so that the weft carbon fiber tows 53 do not turn over the filaments; the lower rapier 15 and the upper rapier 14 of the picking machine are woven by picking and weft picking and beating-up one by one in a cyclic manner by using a weft carbon fiber tow 53 coiled from an oriented fixed length disc 23 and a weft glass fiber yarn 54 coiled from a weft accumulator 16-3, and the mode of picking the upper rapier and the lower rapier together in the prior art is not adopted; the warp and weft carbon fiber tows are firmly bound by warp and weft glass fiber tows after being tiled; although glass fiber yarns are also prone to fuzzing, the weaving method of the present invention is extremely simple in its movement path and does not fuzze. The flat bidirectional carbon fiber cloth 5 woven by the invention and shown in figure 1 has the advantages of no side turning, no broken filaments, uniform tension, ultra-thin and firm performance, no loss of physical indexes, and the user can conveniently use the cloth as a base material for post-treatment such as resin on modeling, etc. so as to manufacture the required application material.
The above embodiments are illustrative of the specific embodiments of the present invention, and not restrictive, and various changes and modifications may be made by those skilled in the relevant art without departing from the spirit and scope of the invention, and all such equivalent technical solutions are intended to be included in the scope of the invention.
