AI Technical Summary

Technical Problem

In the existing technology for spraying vertical honeycomb through-hole ceramics, the airflow cannot evenly cover all the through-hole walls, resulting in insufficient or excessive spraying and uneven coating thickness.

Method used

A wall flow processing mechanism was designed, including a motor-driven rotating shaft and an irregularly shaped shell, with a suction component and a clamping component. By slow rotation and negative pressure suction, the spray material is ensured to uniformly cover the inner wall of the honeycomb through holes, and the clamping component prevents the workpiece from deviating, controls the direction of spray material flow, and improves the comprehensiveness and stability of spraying.

Benefits of technology

It achieves all-around spraying of honeycomb ceramics, improves coating uniformity, reduces material waste, and enhances spraying efficiency and equipment stability.
