AI Technical Summary
Existing rotary atomizers lack an effective mechanism to securely lock the rotating shaft during operation and maintain airtight sealing, leading to potential leakage and operational inefficiencies.
A locking mechanism for the rotating shaft, comprising a locking pin with a spring and compressed air interface, ensures secure locking and airtight sealing by using a spring to prevent engagement when air is off and enabling engagement when air is on, with an O-ring seal to prevent leakage.
The mechanism provides secure locking and airtight sealing, preventing leakage and enhancing operational efficiency by ensuring the locking pin engages only when compressed air is active, thus maintaining a sealed connection.
