The automatic feeding system mainly completes the data state acquisition and output control of the relevant analog and switching quantities of the on-site equipment. The touch screen is used in conjunction with the metering tank PLC, which makes the application of the tank PLC more flexible. The touch screen can set parameters, display data and depict the production process in the form of animation, which makes the application of PLC visualized. The weighing system uses RS232 interface to connect the touch screen to the PLC via communication cable. The remote touch screen (HMIA) and the local touch screen (HMIB) are connected via Ethernet, both of them can display the instrument data and equipment status, and both of them can control the field equipment.

The weighing and feeding system is usually used for batch mixing of two or more raw materials in proportion to each other, and programmed to make the batch mixing continuous, so as to achieve uniformity in the mixing ratio. The human-machine interface is used to input the corresponding proportioning parameters, the signal of each weighing scale is transmitted to the weighing instrument through the load cell, and then the signal is converted by the weighing instrument and connected to the central controller, which, combined with the set formula and according to the real-time data of each weighing unit, controls the charging time and the amount of each kind of material, when all the raw materials are weighed and finished, they all enter into the reactor, and then, after sufficient mixing, enter into the dosing kettle by means of screw or gravity. After sufficient mixing, they will enter into the dosage tank by screw or gravity.

The weighing and feeding system adopts the new WINXP system platform, which is faster and more stable. The real-time dynamic production screen shows the production process, and the operation is intuitive and clear; the powerful report function can record and store a large amount of various types of data and tabulate and print, and it automatically prints the dosage report after the completion of each production, and provides the information of date, time, report number, and the actual consumption of each kind of material; the report extraction adopts the PC manual query method. The report is extracted manually by PC, and the end-of-production report is stored in the computer, which can be read indefinitely to ensure the correctness and completeness of the production report. Simple operation, the system has three production modes: manual, semi-automatic and fully automatic.

Automatic feeding system is a comprehensive automatic system that integrates computer production process control and data management such as weighing and feeding, formula control and discharging. It displays parameters such as temperature, pressure, liquid level, weight and volume in real time, and makes corresponding ultra-high or ultra-low alarm warning for the storage tank according to the conditions. It integrates various control functions, such as pump and valve control and alarm system. It can carry out warehouse management, inventory management, procurement management, cost management and so on.

Feeding system combined with industrial control technology and Internet of Things technology professionally developed a set of flexible and variable production control system software, the production process of the various control points integrated into a control software, the customer only in the central control room can control the entire factory production process. It really realizes a highly integrated, automated and unmanned efficient workshop. Central control data acquisition control system: comprehensive observation, centralized management. With PLC/DCS as the core control, the computer system is responsible for formula calculation, personnel management, data collection, query and printing. The central control computer monitors and controls the on-site production situation, reflecting the operation of each production unit in real time.

The feeding system is an indispensable equipment for the mixing tank, which realizes the process of automatic conveying, storage, weighing and feeding. According to the physical properties of raw materials, all kinds of materials are sucked into the mixing tank by negative pressure once or many times in order, measured and temporarily stored, waiting for the mixing tank feeding signal, and then start the next batch of sub-metering action after completion.

The automatic feeding system adopts DCS control system, the pneumatic, stopping and running of the whole system are controlled and monitored in the control room; the whole equipment is equipped with fault detection system, if the equipment in the rear section fails, the equipment in the front section stops by itself and displays the location of the fault point and the reason, and shows the system running status with alarm light; the control mode adopts three-level control mode: upper machine position → PLC → dosage instrument. The control interface is simple and clear, with animation displaying the dosage process and dosage data, which is clear and eye-catching; the personnel in the control room contact with the field personnel through the walkie-talkie.

Weighing conveyors are ideal for high speed applications, with a large dimensional measurement range and processing efficiency to count packages and provide data for correct sorting. Flexible configuration according to different requirements of users. Used to measure the regular shape of the object transmitted on the raceway, installed above the raceway, no need to separate the transmission belt, the raceway can be bidirectional transmission, the front and rear objects can be placed together through the measuring head, increasing the total throughput.

The weighing and feeding system adopts the screw metering method, and adjusts the material flow by controlling the screw speed through frequency conversion. When the system enters into working condition, the material from the spiral is conveyed and passed through the load cell for weight detection, and the speed sensor installed at the end for speed detection, the detected weight signal and speed signal are sent to the weighing instrument together, and the weight of the material in the spiral is detected and inputted into the totalizer with the help of the weighing module, and the frequency converter detects the speed of the motor, and inputs the speed information into the totalizer. The totalizer will process the received spiral speed signal and weight signal to get the cumulative amount of material and the time flow.
