Manual Liquid filling machine consists of stepping motor, gear pump filling head, conveyor belt and electrical control box, controlled by PLC programmable, the container is fed into the scale body at the same time when the motorized drum running, weighing module on the photoelectric switch detected by the container issued by the signal, the filling mechanism through the speed reducer to stay in the E stepping motor's output shaft is connected to the drive shaft of the ruler wheel pump, through the control of the stepping motor's running steps to achieve the Accurately control the number of revolutions of the gear pump to achieve the purpose of accurate measurement.

The Explosion-proof automatic filling machine realizes the filling operation diagnosis, real-time monitoring, automatic control and so on to meet the requirements of real-time, stability and reliability of the system. Intelligent multi-functional faceplate, man-machine operation interface is simple and suitable, through the RS-422/485 interface can be rapid communication and setup. The control index of the filling weighing is mainly to judge whether the initial weighing and rechecking weighing related indexes meet the weighing requirements, and the automatic adjustment of the liquid level in the storage tank and the intermediate tank in the filling process, and the control design of the peripheral hand-held code scanner are also an important part of the control part.

The Weighing automatic filling machine is mainly composed of filling management, metering and delivery control modules. The central control and management system is connected to the industrial Ethernet to obtain the filling request from the filling system in the workshop, optimize the scheduling, and send the filling instruction to the metering and transfer control system. After receiving the instruction, it opens the corresponding pipeline valves and uses centrifugal pumps and manipulators to carry out transmission and gripping, and automatically transports the product to the corresponding position for control.

The Electronic scale filling machine sends the barcode data to the server by weighing module to get the barrel file data, and then sends it down to the filling scale through the weighing module. It adopts Profibus system configuration with PLC controller as the master and ET200 distributed I/0 as the slave to realize the control of the electronic scale, frequency converter and centrifugal pump as well as the monitoring of the level of each barrel and the manipulator. It accomplishes the functions of status monitoring, alarm display and manual operation of the metering and conveying process.

Liquid Quantitative filling machine filling adopts stepping motor to drive the filling valve up through the screw according to the pre-set speed: when the filling requirement is reached, the filling is closed. Adopting automatic capping, capping, sealing one by one, the filled pail is accurately sent to the automatic capping machine, the capping machine, through the robot, sucks up one pail cap each time and accurately places it on the top of the filled pail, and the automatic sealing machine will immediately cooperate with the action of the pail cap to accurately squeeze the pail cap, sealing the filled pail.

Quantitative filling machine consists of cylinder actuator and weighing module, which is used to monitor the assembly line filling device and related data management to ensure that the equipment to complete the expected operation, and its main function is to achieve accurate measurement of the product material, and the equipment consisting of heating mechanism, automatic capping mechanism, transmission mechanism and other units to complete the work of the product packaging, coding printing, and transportation of finished products.

Automatic filling machine to realize the instrumentation and PLC and the host computer communication connection, real-time processing and the corresponding components of the formula for comparison of the settings. The use of RS485 bus type to realize the connection with the filling machine port, in order to achieve the instrumentation and PLC and the host computer running state is consistent, read through the interface stored in the filling machine touch screen, easy to fill management and query.

The dust-free automatic feeding system is controlled by PLC timing. The mixer is always stirring. During stirring, liquid is added quantitatively. The material bin must be discharged when the material door of the temporary storage hopper is closed (if the temporary storage hopper is equipped with a weighing scale) and the scale is empty. After the material and miscellaneous bin is closed in place, the temporary storage hopper begins to discharge materials. The external storage tank and the in-plant material silo start to feed materials to the screw after a delay. The amount of material fed is controlled by the opening degree of the material door. The start and stop are controlled according to the start and end of material discharge in the temporary storage hopper. All controls are implemented by the PLC for interlocking control, and the PLC controls the sequential start and stop.

The Measurement feeding system is a complete set of automation equipment that realizes dynamic weighing and batching control through electrical control management and visualization man-machine software configuration. The electrical control part of the system adopts Siemens PLC, which is programmed and controlled according to the production requirements; the software adopts human-machine configuration, which controls the weight and flow of the materials loaded into the weighing hopper according to the process requirements through the monitoring system and the PLC program, thus realizing the precise measurement and dosage. The weighing system has strong stability and high cost performance, and can provide accurate measurement data and control means for production control and management of various industrial sites.
