A track 6 is installed on the opposite side of the drying tray outlet, and the drying tray support ring 3 is fitted onto the track 6. A drive device 9 is installed at the front of the track 6, which drives the gate 7 to slide on the track 6. A fixing device 5 is installed on the outside of the heating chamber 1. After the gate 7 moves into the heating chamber 1 with the drying tray support ring 3, it engages with the fixing device 5. In one possible implementation scenario, this device is installed on a contact lens production line.

[0021] Optionally, this device is specifically designed for the curing step of contact lenses. During the curing process, volatile substances are released from the polymerized lens precursor composition. These volatile byproducts accumulate inside the curing oven and must be manually cleaned. Existing ovens have multiple compartments for holding the oven trays, making them difficult to clean and creating many hard-to-reach areas. This device effectively isolates the tray holder from the heating element. During cleaning, simply removing the tray support ring 3 allows for easy manual cleaning of both the tray support ring 3 and the heating chamber 1, saving significant time and improving cleaning efficiency.
