Liquid Automatic filling machine using computers to achieve the human visual function, the machine instead of the human eye to do the measurement and judgment, the use of photoelectric imaging system to collect the image of the controlled target, by the computer or special image processing module for digital processing, according to the image of the pixel distribution, brightness and color information, such as size, shape, color and other identification. This organically combines the rapidity and repeatability of the computer with the high degree of intelligence and abstraction of the human eye's vision, which greatly improves the flexibility and automation of the production process inspection, saves a lot of manpower, improves inspection efficiency and ensures product quality.

Weighing Quantitative filling machine can adjust the size of the filling volume by changing the rotational speed of the frequency converter gear, through the filling valve to the filling container dispensing liquid, control the switch on and off of the solenoid valve, drive the implementation of the lever drive to make the conical spool in the filling valve open or close, realize the liquid circuit intermittent opening and closing, showing the whole filling control process. Also can be achieved by controlling the number of running steps of the stepper motor to accurately control the number of revolutions of the gear pump so as to achieve the purpose of accurate measurement.

Liquid filling machine is a highly automated packaging equipment, its main function is to liquid materials into a predetermined set of weight. In the filling process can effectively avoid the material overflow, to prevent the maximum extent of the material itself on the environmental pollution, so as to effectively protect the operator labor. The system is stable and reliable, easy to operate and accurate in filling. It mainly consists of filling gun device, PLC system control part, weighing system, filling rack table, conveying equipment and so on.

The methanol filling machine reads the data stored in the chip through the interface of the weighing module, processes the data of the weighing module through the serial port, and is responsible for receiving the polling signal sent by the server to the base station to give the response information. If the communication frame is the data frame sent by the server to the base station, the data sent by the weighing module is directly sent to the serial port sending buffer. The received data is checked and simply analyzed and sent to the serial port receiving area to ensure the stability of the signal.

Automatic filling machine has human-computer interaction, communication, display and storage, printing and other functions, which can realize real-time process data monitoring, set up alarms for running process events and switch between manual and automatic control. The computer downloads the program and monitors the operation of the equipment through Ethernet PLC on-line. The computer communicates with PLC through Modbus 485 communication protocol to display the running status of the equipment and set the running parameters for starting and stopping the equipment. The actuator is responsible for executing the commands from the PLC and performing the corresponding actions.

The weighing and dropping system realizes the process control of batching. According to the need of batching, various control function program modules and control subroutines are designed in the control software. It mainly includes "control system state initialization", "automatic work control", "manual work control", "automatic batching", "state test", "fault detection" and so on. The dosing control software follows the automatic control and manual control modes. In order to improve the performance of the batching control system, improve the accuracy and speed of the batching system, and ensure the reliable operation of the control system, effective measures are taken.

Labeling inspection machine consists of weighing module, when the items through the load cell, the load cell records the weight of the size, so that after the analog collection of signals through the conversion needs. Digital signals processed through the microprocessor display, the current display equipment are to apply the liquid crystal display, when the collection of weight data and printing and labeling, these data through the microprocessor can be analyzed, sorted to meet the requirements of the weight of the simplest and most common is the current widely used small electronic scales.

Checkweigher can be selected does not meet the requirements of the set weight value, with the conveyor belt and reject equipment to do not meet the requirements of the weight of the production of mouth separation, to meet the requirements of the pass. Has included a lot of today's needs of the function, using the world's advanced digital weighing unit, to achieve high-speed, stable measurement. Patented scale frame structure ensures accuracy and stability. Multi-mode LCD graphic display operating system, Chinese, English and Korean operating interface, easy to learn. Powerful statistical function to record the inspection data of each shift. Adopting dismounted conveyor belt, easy to maintain automatic counting, automatic rejection of nonconforming products or alarm when encountering nonconforming products. Testing standard weight can be set, real-time display of testing weight and quantity, and display of inspection results.

After the checkweigher gets the weight signal of the product, the system will compare it with the pre-set weight range to sort the product, and the sorting type will be different according to the application, and there are mainly the following types: non-conforming products are rejected, and overweight and underweight are rejected separately, or conveyed to different places, and sorted to different weight categories according to different weight ranges.
