The invention discloses a multi-axial thermoplastic sheet ply discharge platform and system. The multi-axial thermoplastic sheet ply discharge platform comprises a front driving roller, a rear driving roller and a driving motor, wherein the front driving roller and the rear driving roller are located on the same plane; the front driving roller is connected with the driving motor; a conveying belt is mounted on the front driving roller and the rear driving roller; conveying chains are mounted on two sides of the conveying belt, and a plurality of angle and gap control devices are arranged on the conveying chains; and the multi-axial thermoplastic sheet ply discharge system comprises a plurality of multi-axial thermoplastic sheet ply discharge platforms which are connected through linked conveying chains. With the adoption of the angle and gap control devices, ply lamination of multi-axial and multilayer sheets are realized, further, the ply angle can be accurately controlled, and the production efficiency and the mechanical property of a product are greatly improved.
