[0014] Compared with the prior art, the utility model provides a microwave forming device for ceramic processing, which has the following beneficial effects:

[0015] 1. This utility model utilizes the negative pressure generated by the blower during operation to draw air in through the suction nozzle. The air is then discharged outside the microwave drying chamber through the air distribution pipe, the inner cavity of the electric telescopic rod, and the air intake pipe. The electric telescopic rod drives the pneumatic mechanism to gradually descend into the clay vessel. Several suction nozzles arranged around the fixed plate draw the relatively humid air inside the clay vessel out of the microwave drying chamber. As the air pressure inside the clay vessel decreases, air from outside the clay vessel is drawn into it, achieving air circulation between the inside and outside of the ceramic clay vessel to improve drying efficiency.

[0016] 2. This utility model uses an infrared ranging probe to detect the spatial distance of the inner wall of the ceramic clay vessel from a radially outward-facing laser detector, thereby activating the motor and adjusting the distance between the air inlet of the suction nozzle and the inner wall of the ceramic clay vessel to a suitable range. Meanwhile, another infrared ranging probe is used to detect the spatial distance of the bottom wall of the vessel from a vertically downward-facing laser detector. When the suction nozzle approaches the bottom wall of the ceramic clay vessel, the electric telescopic rod starts to pull up the pneumatic mechanism, causing the suction nozzle to rise. This maintains suction power while preventing contact with the ceramic clay vessel throughout the process, thus avoiding any impact on the structure of the ceramic clay vessel and further improving the drying efficiency of the ceramic clay vessel.
