Metering filling control machine

CN2573468Y
Metering and filling control mechanisms include stepper motors, screw rods, pistons, metering cylinders, combination valves, and controllers. The stepping motor is connected with one end of the screw rod, the other end of the screw rod is connected with the piston, the screw rod and the piston are arranged in the measuring cylinder body, the controller controls the action of the stepping motor and the combination valve, and the stepping motor drives the screw rod and the piston The reciprocating motion in the measuring cylinder. Compared with the prior art, the metering and filling control mechanism has the advantages of simple design structure, high filling accuracy, and wide range filling.
