The automatic feeding system adds materials in proportion to the set ingredient quantity and performs feedback adjustment based on weight. The ingredient quantity and lag time can be set. When the drop value changes, the magnitude of the change and the magnitude of the ingredient adjustment can be set. Relevant quantities to be monitored and set (such as drop value, post-filter weight, etc.) can be selected.

​The metering batching system consists of a central feeding hopper, loading and discharging valves, and control equipment. A flap is installed in the central feeding hopper to control the loading of the 1st and 2nd weighing hoppers. The material conveyed by the belt conveyor passes through the flap in the central feeding hopper and falls into the weighing hopper set at the lower limit. When the weight of the material in this weighing hopper reaches the upper limit (full), the weighing instrument of this hopper will output two signals to control the flap in the central feeding hopper to switch, transferring the material from the 1st weighing hopper to the 2nd weighing hopper.

Quantitative Batching system realizes intelligent and networked management of small material batching, so that finished products and raw materials can be traced in both directions, production decision-making and production control are seamlessly connected, production execution is improved, and real-time and accurate production data are used as the basis for managers' decision-making, so as to prevent the occurrence of quality accidents. Help customers to solve the dosage error prevention, improve dosage precision, quality traceability products, intuitive image, over the limit of the sound and light alarm prompts the application of bar code to effectively prevent the occurrence of the wrong raw materials raw material lot number bar code and finished product lot number bar code fixed in the bar code block can be reused.

The given batching system uses rotor pumps for feeding and automatic metering control. A weighing module is installed under the material tank to monitor the batching weight. When the added materials in the tank meet the formulation requirements, the feeding will be automatically stopped and the delivery will be automatically shut off. A closed-loop weighing system composed of a computer and a frequency converter speed regulator is used.

The weighing of the reaction tank is transmitted from the industrial computer in the control center to the electronic scale and PLC controller through the communication line, and the weight of each link is collected and displayed, and the fast feeding and slow feeding strategies are adopted in different weight stages to improve the efficiency and the measurement accuracy of the electronic scale. When the ingredients reach the target value, the output stop measurement signal, and the related valves and pumps are closed by PLC control. At the same time, the action of unloading the reactor is completed, and the measuring instrument is automatically zeroed and peeled.

Automatic discharge system for a variety of different types of materials for conveying, proportioning, heating, mixing and finished products of the entire production process of automatic production lines. Control the action instructions of each part of the ingredients to fully complete the conveying of materials, accurate ratio, mixing, transportation and other processes. Through the material conveying device, all kinds of materials are automatically transported to the silo, and then automatically weighed in proportion and accurately, and then the mixed materials with a good ratio are automatically transported to the silo for mixing, and then automatically discharged after mixing.

The weighing and discharging system will reflect the running status of loading, batching, feeding and related equipment in the form of dynamic pictures according to the actual process of batching technology. When there is an over-limit fault during operation,  will appear Chinese character alarm warning, and start the alarm (sound and light), or stop the machine, or change the warehouse, and analyze the control status of the operation data. The dynamic batching process of the system is reflected by different color histogram.

The hazardous waste weighing system provides a human-machine interface to complete functions such as inputting control information, data management, displaying data, storing, statistics, and generating reports. The industrial control computer inputs the weight of the ingredients through the host keyboard, and based on the ratio of raw materials, generates the weights of various materials. These weights are then transmitted to the PLC through communication. During the ingredient mixing process, real-time dynamic monitoring is carried out. The detection signals and other switch quantities sent by each slave machine and the control system are collected at regular intervals, and the weight signals of each material are collected in real time and compared with the given signals to determine the next control scheme. At the same time, the weight signals are transmitted to the upper computer.

The feeding system adopts Siemens PLC to control the automatic operation of all its interlocking devices (start-stop, interlocking, position switching and other operations), and the upper computer is programmed by Siemens WINCC configuration software. The whole configuration operation screen is embedded into the whole weighing system, and the operation of equipment start-stop operation, operation display, fault inquiry record and maintenance are carried out. The system has the characteristics of friendly interface, concise operation and reliable operation.
