AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.

Abstract

A locking mechanism for a rotating shaft can include a locking pin having a locking pin shaft side and a locking pin spindle side, a compressed air supply port in fluid communication with a compressed air supply source, and a spring configured to place the locking pin spindle side in direct mechanical communication with the compressed air supply port when the compressed air supply source is not activated.
