The liquid Filling machine is composed of electrical control of the control unit and detection unit. It uses flexible and high-performance computer intelligent batch management to achieve filling control. It adopts Modbus protocol to communicate with the host computer to facilitate measurement management and control, meet the production of different products and different batches of the same product, flexibly set different filling quantities for filling, and uses the original imported quality testing equipment. Ensure that the measured flow rate does not change with temperature and pressure changes, rapid and accurate measurement; Less equipment composition, easy maintenance, low failure rate, high filling efficiency; With good interface expansion function, it is suitable for the intelligent upgrade of information management.

The filling process of automatic filling machine is mainly divided into several parts: cap removal, gun insertion, barrel removal and return. When the barrel is put into the working platform, the manipulator grabs the protective bottle cap under the drive of the cylinder, and then the working platform is moved to the end position. When the barrel is in place, the filling gun assembly is lowered under the drive of the cylinder, and the gun head is inserted into the barrel. Divided into high and low double head components. The solvent used for dilution is pumped from a high level by a peristaltic pump, which increases the pressure in the barrel so that the liquid reaches the target value. The upper control unit of the stepper motor based on ISA bus forms a master-slave control structure with the industrial computer. The industrial computer is responsible for the management of the human-computer interaction interface and the operation of the control system, and completes the filling work. At the same time, it can connect the position, speed, limit and other signals to realize the position detection, protection and other functions.
