Quantitative filling machine using photoelectric imaging system to collect the image of the controlled target, by computer or special image processing module for digital processing, filling head down control motor to reach the weight to stop, the weight reaches the issued signal, the solenoid valve stops moving, the filling valve filling is complete, the filling nozzle rises, to complete the filling process.

The main use of quantitative filling machine servo motor to realize the rotor pump stroke control, and then realize the filling volume control. Before filling, the front weighing module obtains the weight of empty barrel, after filling, the rear weighing module obtains the weight of filling and transmits it to the weighing instrument, which will read out the filling data in real time to get the weight deviation, and the filling algorithm calculates the control volume of large materials, the weighing system will send the control volume to the servo drive, which will drive the quadratic rotor pump to perform the early closure of the small material volume and then control the filling valve of the small material, and the upper computer will read out the filling data in real time through the Ethernet connection with the weighing instrument. The upper computer is connected to the weighing instrument via Ethernet to read the filling data in real time, and the process parameters can be set to monitor the operation of the production line.

Small material filling machine through the cylinder drive a piston to extract and hit the material with a one-way valve to control the flow of materials, with a reed switch to control the cylinder's stroke to regulate the amount of filling, the use of weighing module and weighing instrument connected with a data line, in the process of measurement of electronic scales of pressure signals are constantly transmitted to the weighing instrument, in the preset quantitative weight to control the meter control to stop the pump, close the pneumatic valves.

Ethanol Filling Machine reads the internal state of weighing instrument and real-time data of quantitative filling in real time, and displays the data in the upper computer, with report function, it can generate daily report, real time report, monthly report, annual report and so on. Dynamic addition and modification of the reports, by setting the permissions that give the technician or operator the right to modify and add the filling forms, while recording the date of modification and the number of operators. Power failure recovery function: in case of sudden power failure, the measurement records before power failure can be recovered; LAN sharing function, the host can share the data in LAN, which is convenient for the workshop supervisor to know the progress of the project and so on.

Pus Liquid Filling Machine is mainly used to collect the set value of filling quantity, process the pulse signal of weighing module, drive the relay to drive the frequency converter to control the motor and centrifugal pump to convey the material, calculate the pulse signal of pipeline tube flow through weighing module, get the weight of liquid actually discharged from the weighing system, and control the operation of the motor according to the difference between the actual filling quantity and the set value, so as to realize the precise control of filling quantity according to the actual need.

Pesticide filling machine is realized by the fast and slow pulse frequency input through weight sensing. In order to achieve the purpose of adjustable measurement size and improve measurement accuracy, the adjustable speed of screw and accurate positional positioning are required, and the stepping motor is adopted to control the speed and number of revolutions of the screw. In the case of not overloading, the speed of the stepping motor, and the position of the stopping only depend on the frequency of the pulse signals and the number of pulses, and are not affected by the load change.
