AI Technical Summary
When traditional pressing devices absorb the filter at the adsorption end, they require a large suction force and the steel ball is easily displaced during the pressing process, resulting in a decrease in the air pressure in the confined space, affecting the pressure-assembly effect.
Design a solenoid valve end filter pressing device, which is arranged in the suction channel in the suction head to avoid the mesh hole in the center of the opening filter, and matches the suction channel through several positioning protrusions, so that the adsorption is more firm, and a vacuum generator is used. And pressure reducing valves control the airflow size to prevent the steel ball from shifting.
It reduces the demand for suction and the risk of steel ball displacement, and achieves a more stable filter pressing effect.
