Feeding system through the weighing and feeding, formula control, mixing homogenization, material conveying and other processes, the use of microcomputer control and data management as one of the integrated automation system, the use of Mitsubishi or Siemens series PLC and industrial microcomputer to establish a high-performance control platform. Industrial control microcomputer, Mitsubishi or Siemens series PLC communication module and switching input/output module, as well as manual/automatic control switch, manual control button and indicator light are installed in the integrated control cabinet, easy to operate; Customized according to the basic requirements of the Batching system and the actual needs of users; High precision weighing module combined with weighing instrument; Using pneumatic valve control, screw frequency conversion for feeding and discharging control; Configure related mixing equipment according to material mixing and customer requirements; Screw feeding or pneumatic feeding is used to feed the specified position.

The Weighing system is mainly composed of raw material warehouse, electric vibration Feeder, hopper scale, weighing sensor, bucket door motor and computer control system. According to the requirement of the task, the high precision weighing system is applied to the weighing of metal powder on the assembly line. The system adopts the intermittent static weighing principle, according to the technical requirements, weighing 30 times per minute, that is, each cycle (2s) to complete the process of feeding, weighing and discharging. At the early stage of operation, the computer starts the electric vibration machine to send the raw materials into the weighing hopper, then the weighing sensor sends the material weight signal to the computer through the A/D conversion module and converts it into data. When the material weight data is equal to the weighing set value, the computer controls the electric vibration machine to stop, and then starts the hopper door motor to open the material port and send the raw materials into the next process bin. Considering that the blanking speed is too slow will affect the production, so the system adopts the blanking mode of first fast and then slow. When the material weight in the weighing hopper is set for the weighing, the fast vibration of the electric vibrator is switched to the slow vibration to stop, which can accelerate the batching speed of the batching system. Finally, the weighing system first discharge material, when the material head is transmitted to the hopper of the previous weighing system, open the discharge port of the weighing system, and so on. At this time, the computer starts the motor of the hopper door to close the discharge port of each weighing system to prepare for the next batching.

The electromagnetic vibrator feeding system is mainly used in the equipment of particles and powder materials for loading of weighing systems or feeding of belt conveyors. The electromagnetic vibrator has many advantages compared with other mechanical feeders, such as simple mechanism, no rotating parts, no deceleration mechanism, no need for lubrication and refueling, small size, easy maintenance, small driving power required, small starting current, the material in the feed trough according to the parabolic track jump forward, the trough wear is small, suitable for conveying wear and high temperature materials, Easy to start and stop, high control accuracy. The system uses two electric vibrators. The upper vibrator feeds the bucket bin of the Electronic scale, the lower vibrator disloads the finished materials and puts them into the bin, and the hopper scale uses pressure control weighing module to detect the weight. When loading, the power on vibrator works and sends the material into the hopper scale. After the weight is measured by the weighing module, it is sent to the processor. When the predetermined weight is reached, the computer sends a signal to stop the power on vibrator and start the power off vibrator at the same time, and the material in the hopper scale is removed and enters the mold.
