The hydrochloric acid filling machine adopts the filling mode on the liquid surface, which is suitable for filling a variety of foam-free liquid materials. The unique design of filling head device is easy to operate, and the filling is fast and accurate. It has a relatively complete function of data recording and statistical reporting, which meets the needs of enterprise production management. All kinds of reports include: shift operation report: including the start and end time of each shift, the control target value set according to the formula, the operation data of each scale, filling output and average output, etc.
020-34563445The automatic Filling machine has both on-off control and analog variable frequency speed control. The equipment can run automatically and continuously, and each movement point can be manually inched, so there are many input points corresponding to various operations and output points of action state information to be displayed. The scheme of combining PLC with touch screen is adopted. The screen of the touch screen is designed with special configuration software and then downloaded to the touch screen through the RS-232C serial communication port of the computer. The communication between PLC and touch screen is through serial interface, and the connection is simple.
Weighing and filling machine frequency conversion speed control system analog input point and an analog output point, speed motor measuring motor speed, voltage value signal access analog input point, after comparison with the given value, PID operation, the results of the operation from the analog output point output, as the control signal of the frequency converter, to achieve frequency conversion speed control. The main control unit adopts PLC product CPU224, plus two digital expansion modules EM223 and one analog expansion module EM235. The touch screen adopts Taiwan-made PWS3260, the analog input point of the frequency conversion speed control system and one analog output point, the speed measuring motor measures the speed of the motor, and the voltage value signal is accessed to the analog input point, which is compared with the given value and the PID arithmetic, and the arithmetic result is output from the analog output point to realize the frequency conversion speed control signal. The operation result is output from the analog output point as the control signal of the frequency converter to realize frequency conversion speed regulation.
The control program of the Filling system is prepared in the form of menu. The automatic functions include: run, pause, terminate, reset and so on. Manual functions include: advance, retreat, start, stop, etc. of all moving parts. The alternating button function in ADP3 configuration software is utilized for programming. When the button is pressed and lifted, the corresponding intermediate relay of the PLC is set respectively, so that the PLC realizes the in/out control of a certain moving part. Initial value setting: set the rotational speed, counting value and other parameters arbitrarily according to the user's demand, and monitor the upper limit of the parameter, and give a prompt once it is out of bounds. Operation monitoring: monitor the state of each device of the system, such as the abnormal state of the frequency converter, motor, etc., and protect it by power failure in time, and give an alarm.
