The automatic Dosage system consists of an industrial computer as the upper computer, PLC programmable controller as the lower computer, powder dosage, liquid dosage, micro dosage and control system. This control system is a kind of automatic Weighing system with vacuum feeding, dosing screw quantitative dosing, weighing hopper automatic weighing and dosing, and cumulative weighing at the same time. It is suitable for precise measurement of materials and automatic batching operation in the production process.

The structure of weighing mixer consists of high level bin, valve, vibrating motor, weighing module and reactor, and a set of position detection device. During the dosing waiting phase, the mobile drum stops on the Electronic scale and at the position of the reaction tank dosing port to wait for the control command. According to the charging parameters entered by the operator, the silo valve opens to discharge the material. The amount of feed is continuously collected through the weighing module, and the valve is closed when it reaches the dosing set value of one advance, which can be calculated by the time of the valve or obtained by experience. When the added material reaches the specified weight, the valve is closed automatically.

Automatic feeding system composition

1, the dosage machine mainly completes the powder and a variety of liquid material dosage mixing, metering tank is set up separately, the liquid raw materials are separated from the measurement of the dosage, the bottom of each raw material tank are installed with a feeding pipeline, respectively, by the automatic valves and manual valves to control the switch, the automatic valve for each type of liquid material is installed close to the pipeline exit position, the feeding pump is responsible for the material through the pipeline to the metering tank, the feed pump at both ends of the return pipe and the return valve is set aside, the return valve is installed at the inlet of the metering tank, and the return valve is installed at the inlet of the metering tank. Measuring tank inlet installation of automatic valves, to achieve fast and slow feeding control of materials; liquid or powder through the pipeline can be added directly into the measuring tank, measuring tank of the four support feet and the support frame between the bottom of the installation of Weighing modules, responsible for the measurement of the weight of the material into the measuring tank.

2, through the measurement of the bottom of the tank's automatic diversion device, were automatically added to the corresponding mixing tank, in the measurement of the tank's total discharge valve after the installation of water body flat to each mixing kettle material automatic valves, the front end of each material automatic valves feed pipe with pipeline linkage, so that you can ensure that after unloading no material at all, to the unloading of each mixing kettle pipeline powder and liquid pipeline can be merged with a pipeline to reduce the cost of materials, pipelines, and the liquid material pipeline, the liquid material pipeline can be added directly into the measurement tank. Material cost. The stirred finished product is pumped to the finished product tank through the pipeline at the bottom of the reaction kettle, which is controlled by the automatic valve and pump.

3,All the dosage data are stored in the industrial computer database of the control center, and the dosage process is monitored by the configuration software, and the process operation is implemented through the control interface, and the production data are stored in the system database at the right time in order to complete the progress of storage and analysis of all kinds of production data, and at the same time, it can also achieve the management of raw materials and storage of materials, finished product management, personnel management, contract management and other functions.
