The weighing machine uses the open-source embedded ACID associative database management system written in C language to obtain the filling data on the production line in real time (production time, filling weight, recording time), and store the data into the database, and then manage the data.
020-34563445Liquid Filling machine adopts constant pressure timing mode, that is, in the case of ensuring the liquid storage tank level is relatively stable, the filling amount is converted into the opening and closing time of the pneumatic Angle seat valve, so as to achieve quantitative filling. The time coefficient is determined according to the method of field measurement, and the opening time of the filling valve is obtained by dividing the filling amount by the time coefficient. Due to the deviation of the diameter of each filling valve channel, each filling head should add a filling correction time on the basis of the main opening time, and all parameters are set by the touch screen of the weighing filling machine. The calculation of the opening and closing time of each filling head is automatically calculated by the PLC, and the final use of this time to control the opening and closing of the pneumatic Angle seat valve, so as to achieve quantitative filling.
All parameters of the automatic filling machine are set on the touch screen, and the PLC works according to the preset program. When the filling is started, the conveyor starts operation, the outlet cylinder is closed, the inlet cylinder is opened, and the filling bottle is sent to the filling area. When the photoelectric switch for the bottle detection detects the sufficient number of bottles, the inlet cylinder is closed, the conveyor stops, and the left and right lifting cylinders move at the same time, driving the fixed frame to move downward. When all the filling bottles are ensured to enter the guide sleeve of the bottle and reach the lower limit, All filling quantitative Angle seat valves are opened, and when the total opening time reaches, the Angle seat valve is reset and closed. When all the filling quantity Angle seat valves are closed, the left and right lifting and lowering cylinders are retractable, the fixed frame drives the filling valve to move upward under the action of the reset spring, when all the filling bottle mouth leaves the bottle mouth guide sleeve and reaches the upper limit, the outgoing cylinder drives the bottle door knife to open, and the conveyor starts. When the outgoing bottle detection photoelectric switch detects that all the filling bottles have moved out of the filling area, The outgoing cylinder closes and enters the next working cycle.
