AI Technical Summary

Technical Problem

Existing aerosol can valves are difficult to adjust in direction during transmission and have limited functionality, making them unable to adjust height and volume, which affects production efficiency.

Method used

A valve assembly was designed, comprising a valve seat, an outer valve ring, an upper cover plate, a valve lifting spindle, a valve guide rod, a valve fixing shaft, a valve worm gear, a valve seat, and a valve gear. The valve's direction and height can be adjusted through a rotation and lifting mechanism. Combined with inner and outer guide rails and a worm gear structure, the valve can be flexibly adjusted.

Benefits of technology

The valve allows for flexible directional adjustment and height adaptation, improving the efficiency of aerosol can production and achieving a high-efficiency production capacity of 160 cans/minute, while ensuring the reliability and safety of the equipment.
