[0028] The working principle of this utility model is as follows: The fifth driving component drives the fifth stop block to close the discharge port. The vibrating plate feeds multiple gemstone materials into the material channel through the feed port. The placement platform is in a horizontal state and is in contact with the second platform. During operation, the third and fourth driving components are respectively pressed against the placement platform. The pushing mechanism moves the pushing block towards the placement platform. When it reaches the fifth stop block, the first material alignment is performed. After alignment, the fifth driving component drives the fifth stop block to descend, opening the discharge port. The pushing mechanism pushes the gemstone materials from the discharge port into the first limiting groove of the first limiting block. After the gemstone materials are aligned, the fourth driving component moves to raise the second limiting block, while the pushing block continues to move. The material is pushed towards the stop bar. After it reaches the stop bar, the push block retracts. The fourth drive component then presses the gemstone material into place. After pressing, the third and fourth drive components move synchronously to rise. The tilting cylinder drives the placement platform to change from a horizontal to a vertical state. After the change, the first drive component drives the first slide table to move forward along the first slide rail module. After it moves into place, the gemstone material is placed against the polishing assembly for polishing. After the polishing is completed, the first drive component drives the placement platform to retract and reset. The unloading mechanism pushes the gemstone product off the placement platform for unloading. After the unloading is completed, the tilting cylinder resets the placement platform from a vertical to a horizontal state for feeding the next batch of materials.

[0029] This invention utilizes a discharge seat with an arc-shaped feed inlet to input gemstone materials. Combined with a material trough for arranging the materials, it saves time and steps in discharging and arranging. A pushing mechanism automatically pushes multiple gemstone materials from the trough onto the placement platform, improving feeding efficiency. A pushing limit mechanism with baffles ensures the gemstone materials are positioned correctly on the platform, repeatedly pressing and limiting them to ensure they adhere to the platform surface, guaranteeing the quality and uniformity of subsequent polishing. A flipping mechanism quickly rotates the platform from horizontal to vertical, changing the orientation of the gemstone materials from upward to forward, facilitating polishing by the front-facing polishing mechanism. This invention automates the discharging, feeding, pressing, and flipping of gemstone materials, improving feeding efficiency, reducing manual labor, and increasing subsequent polishing efficiency.
