[0014] The present invention provides a continuous fiber composite material rotary structure multi-axis integrated 3D printer. It has the following beneficial effects: (1) The invention drives the screw drive device and the moving frame to rotate by rotating the disc, and the rotation of the moving frame drives the multi-axis integrated printer to achieve 360-degree printing. At the same time, the screw drive device drives the moving frame to move up and down by rotating forward and reverse. The up and down movement of the moving frame drives the multi-axis integrated printer to move up and down. The multi-axis integrated printer can be moved up and down to achieve printing at different heights. The upward movement through the card slot will be limited by the limit plate to prevent the vibration generated during the rotation process from causing defects in the printed parts and affecting the printing effect. The mold is clamped by the clamping plate to prevent the centrifugal force generated during the rotation of the rotating device from causing the mold position to shift and affecting the part printing.

[0015] (2) In the present invention, the movement of the connecting plate toward the mold will drive the slide bar toward the mold, and the movement of the slide bar toward the mold will drive the correction plate toward the mold. The position of the mold is corrected by the correction plate to prevent position deviation from causing problems with the printed parts. At the same time, the lifting device moves downward, and the movement of the L-shaped short plate away from the mold will drive the trapezoidal plate toward the triangular block. The trapezoidal plate will push the triangular block and the slide plate upward. The upward movement of the slide plate will separate the printed parts from the mold, preventing the parts from sticking to the mold and affecting the demolding effect.

[0016] (3) In the present invention, the protruding rod moves toward the direction of the triangular block and contacts the rotating block, which is limited by the limiting block. The protruding rod moves toward the direction of the triangular block and pushes the rotating block to move upward. The upward movement of the rotating block drives the triangular block and the sliding plate to move upward. The vibration generated by the contact between the rotating block and the protruding rod allows the printed parts to be better separated from the mold, thereby improving the demolding effect. At the same time, the sealing plate moves away from the triangular block and is separated from the sealing ring, allowing the heat exhaust pipe to open. By opening the heat exhaust pipe to cool down, the print bed can be prevented from overheating, which helps to control the temperature uniformity during printing and avoid material shrinkage or warping.
