The automatic batching scale is used to feed different raw materials into the respective hopper in the feeding equipment, then feed into the weighing hopper according to the given ratio of the formula, and weigh, and then feed into the mixing machine for a certain period of time for mixing, and evenly mixed into finished products. Various fixed formulas are inputted into the computer beforehand, and the computer controls the discharging, weighing and mixing according to the proportion of the formulas, and detects the signals of the weighing module in real time, makes a judgment, and sends out the commands to each actuator of the dosage, so as to realize the automation of the dosage. The whole production system is equipped with a manual control auxiliary mechanism, which can control the operation according to the automatic or manual working mode.

The dosage scale consists of an industrial computer, a PLC, an industrial weighing instrument, a frequency converter, a vibration motor, a mixing machine, a sensor, a conveyor belt and other components. PLC provides human-computer interaction interface, completes the functions of control information input, data management, data display, storage, statistics and reports, etc. According to the operator's instruction, it reads a certain numbered recipe, and then according to the proportion and sequence of ingredients in the recipe, PLC sends out the instruction to start the batching, which makes PLC able to start a specific frequency converter.

Batching scale to achieve material transfer, batching control, formula design, production data management and other functions. And it can realize the collection control of multiple ingredients through the network. With PLC as the next machine ingredients, once the production plan is completed in the entire production process, the computer will weigh each raw material according to the plan, no longer need manual intervention. In this process, the worker only takes the material, and the computer checks the weight through the data sent by the electronic weighing, which reduces the work burden of the worker and improves the work efficiency.

The electrical part of pneumatic batching scale is mainly composed of weighing sensor, weighing instrument, programmable controller (PLC), inverter, industrial computer and printer. In the process of dynamic weighing, the weight signal of the weight sensor on the quantitative weighing hopper is received. When the weight of the material in the hopper reaches each set value, the output I/O quantitative signal to the PLC. PLC collects the quantitative output signal of the weighing instrument, and controls the output frequency of each frequency converter through PLC, so as to control the thickness and fine feeding amount of the corresponding vibration feeder and the switching door action of each weighing hopper.

The dosage scale is divided into material storage, dosage, measurement system and electrical control system, the formula feeding and discharging are all controlled by computer. Through the instrument or touch screen, the required weight of various materials is set, and then automatically conveyed to the dosage scale by the winch in sequence for weighing and flow control, so as to realize the measurement and dosage.

Batching scales through a variety of materials were automatically quantitative weighing to complete a dosage of automatic batching equipment, powdery materials for the control of feeding, dynamic measurement, continuous delivery of production metering equipment. Pre-given mass ratio, the equalizer for the weighing of several substances in the dosage measurement. Divided into single tube single layer and double tube double layer, single tube single layer together with the completion of measurement and transportation, double tube double layer structure, the upper layer to complete the flow stabilization and transportation, the base layer to complete the measurement and transportation, the effect of flow stabilization is better and save space.
