A connecting gear is fixedly installed at the center of the outside of the hollow rotating cylinder. A drive gear is fixedly installed at the bottom of the drive shaft.

[0014] Beneficial effects: This invention provides a rapid prototyping machine for Arctic wing molds, offering the following advantages: Through its structural design, the device allows meat paste and minced meat to be added separately to a coaxial double-helix feeding structure. This structure separates the meat paste and minced meat into inner and outer paths, eliminating the need for two independent feeding systems. A servo motor is then activated, driving a gearbox that in turn rotates the coaxial double-helix feeding structure. This rotation conveys both inner and outer materials downwards. The materials enter from the two inlets of a Y-shaped mixer, where they are thoroughly mixed before entering the molding die. The molding die shapes the mixture, and the shaped filling is separated by a cutter. The Arctic wing pieces are then passed through a roller cutter and fed to the next process. Compared to existing technologies, this invention, through its coaxial double-helix feeding structure design, effectively solves the problem of large footprint in traditional dual-feed hopper systems. This structure integrates the conveying channels for minced meat and meat paste onto the same axis, achieving synchronous conveying of both materials through nested spiral blades. Compared to traditional parallel-arranged dual-feed hopper systems, the equipment width is reduced, resulting in a more compact overall structure. This significantly improves space utilization and is suitable for the high-density production line needs of modern food processing enterprises. Attached Figure Description
