The invention discloses a textile fiber press molding machine adopting the principle of staggered flat combing. The textile fiber press molding machine structurally comprises a servo cabinet, an inspection door, a processing table, heat dissipation grooves, a main machine body, fixing foundation feet, a storage cabinet and a controller. The controller is mounted at the top of the storage cabinet in an embedded mode. The back surface of the storage cabinet is fastened with the right end of the surface of the main machine body. The processing table is used for laying and conveying textile fibers, at this time, a press plate is pressed downwards for molding, a separation mechanism is driven to increase the distance between conveying components, thus, the dragging intensity to the fibers is increased, the fibers can be more uniform and even, then, the fibers are shifted left and right and flatly combed through a flat combing component, the fibers are distributed effectively and extensively, deformation after pressing due to large-scale stacking is avoided, and the uniformity of the textile fabrics is prevented from being affected.
