Description

TECHNICAL FIELD

[0002] In the zinc oxide pressure sensitive ceramic processing process, the zinc oxide pressure sensitive ceramic blank body formed by pressing needs to be sintered, and because the zinc oxide pressure sensitive ceramic blank body needs to add adhesive glue in the preparation process, the zinc oxide pressure sensitive ceramic blank body after stacking is easy to stick together and difficult to separate during sintering. Therefore, before sintering of the zinc oxide pressure sensitive ceramic blank body, a layer of anti -sticking powder is usually scattered on the surface of the zinc oxide pressure sensitive ceramic blank body, so as to avoid sticking.

[0003] The current zinc oxide pressure sensitive ceramic blank body anti -sticking powder scattering mode is usually as follows: first, the zinc oxide pressure sensitive ceramic blank body is single -layered and laid on the tray, then the hand -held screen with anti -sticking powder is shaken back and forth above the zinc oxide pressure sensitive ceramic blank body, so that the anti -sticking powder is evenly deposited on the surface of the zinc oxide pressure sensitive ceramic blank body after falling from the mesh, and then it is stacked and sintered.

[0004] This powder scattering mode has many problems in actual production: 1, the area of the hand -held screen is usually small, and the worker needs to move the screen position to scatter powder, and the efficiency is low; 2, when the worker moves the screen back and forth, the amount of anti -sticking powder received by the zinc oxide pressure sensitive ceramic blank body in different areas is different, and there are some areas too much and some areas too little, which affects the effect of anti -sticking; 3, the anti -sticking powder is very light, and when the worker scatters the powder, the anti -sticking powder will be filled around the whole operation table, which has certain harm to the health of the worker; 4, the operation table and the ground are full of anti -sticking powder, and the working environment is dirty and messy.
