[0040] Working principle and technical effect of the present invention:

[0041] When the rotary drive component 2 drives the molding rotor 1 to rotate, the baffle plate 13 and the molding port 103 are correspondingly fitted to each other, and the baffle plate 13 realizes the sealing of the molding port 103, and then the raw material is added into the molding rotor 1 by the feeding pipe 8, and the liquid level of the raw material in the molding rotor 1 is detected by the sensor group 11, and a pressurized cavity is reserved at the top of the molding rotor 1; during the extrusion molding process, the rotary drive component 2 continues to drive the molding rotor 1 to rotate, thereby the baffle plate 13 and the molding port 103 are separated from each other, and the inflation pressurization component 9 introduces gas into the pressurized cavity on the top surface of the molding rotor 1, so that the raw material in the molding rotor 1 is pressurized and quickly discharged from the molding port 103 and molded. During the rotation of the forming rotor 1, the centrifugal force can be used to keep the formed sheet straight; when the rotating drive assembly 2 drives the forming rotor 1 to rotate and is formed by the forming port 103, when the baffle plate 13 moves to the forming port 103 and seals the forming port 103, the cutting knife 704 of the cutting knife assembly 7 cooperates with the matching knife plate 102 to cut the formed sheet, thereby processing the formed sheet in a reciprocating cycle; after the cutting knife 704 of the cutting knife assembly 7 cooperates with the matching knife plate 102 to cut the formed sheet, the formed sheet slides downward under the obstruction and collection of the outer baffle shell 501 and falls on the conveyor belt 4 from the lower discharge port 504, and can be transported and discharged by the conveyor belt 4.
