[0021] 3. When the oil-resistant powder coating is sucked and measured, the piston rod of the second cylinder pulls the rotating column to drive the shift block to rotate downward. At this time, the mounting seat of the second cylinder and the hinge shaft of the hinge seat rotate, and the rotating column drives the shift block to rotate the rotating shaft along the metering block, so that the rotating shaft drives the cylindrical block to rotate along the metering block until the through hole is vertical and stops. At this time, the connecting groove is connected to the metering tube, one end of the through hole is connected to the feed pipe, and the other end of the through hole is sealed with the metering block, which facilitates the suction and metering of the oil-resistant powder material by the metering tube, improves work efficiency, and ensures that the oil-resistant powder coating can accurately enter the metering tube through the feed pipe, thereby achieving precise metering, preventing leakage of the oil-resistant powder coating, and ensuring the cleanliness of the working environment and saving of coatings.
