Liquid filling machine is a high degree of automation of filling equipment, its main function is to liquid material into a predetermined weight. The drums in two states before and after filling are loaded on the high-precision electronic scale once by the manipulator. The controller obtains the electric signal of the high-precision electronic scale through the bus to obtain the tare and the total weight. After calculation and processing, the net weight and deviation value are obtained by comparing with the standard value.

The drums in two states before and after filling are loaded on the high-precision Electronic scale once by the manipulator. The controller obtains the electric signal of the high-precision electronic scale through the bus to obtain the tare and the total weight. After calculation and processing, the net weight and deviation value are obtained by comparing with the standard value. The controller determines whether the net weight of each barrel is beyond the limit by comparing, and the barrel whose filling weight does not meet the standard will be removed by the controller when it flows through the next station with the conveyor belt, so that it enters the waste removal channel, and the qualified product will enter the next station. At the same time, the filling CAM curve of the filling pump is adjusted online through the deviation value, that is, the displacement of the piston movement of the plunger pump is adjusted to adjust the filling amount, and so reciprocating until the liquid filling weight meets the standard. At the same time, the weighing instrument transmits the weighing data to the server in real time for data recording and analysis, and connects with the industrial computer through the switch to realize the visualization of the data and facilitate the operator to monitor the running state of the machine at any time.
The real-time measurement and control information and fault information of the Liquid filling machine are collected by the external weighing module and stored in the embedded database through the data processing program. The status of each control point can be obtained and updated in real time, and the command can be issued to achieve the purpose of real-time monitoring and control. Servo motor and drive system are used to realize the displacement and rotation of the filling pump. The main measuring parts of the filling pump are made of new composite ceramic materials which are resistant to wear, corrosion and high temperature. The filling pump has the characteristics of no adsorption liquid, no chemical reaction with liquid, accurate measurement, long service life, etc. The device has the characteristics of easy assembly, easy disinfection, long life and high precision. When the piston rod moves from top to bottom, the liquid flows into the pump through the piston rod groove to complete the liquid suction action, and then the piston rod rotates 180°, and then the piston rod moves from the bottom to the piston rod groove to pump out the liquid, the piston rod rotates 180° and returns to the initial state, so that a movement cycle of the piston pump ends.
