In the granular batching system, when the weighing module detects a shortage of material in the hopper scale, the pump motor starts and operates. The set feeding time and the feeding motor are activated and operate until the weighing module detects that the hopper scale is full of material, at which point all the working motors stop. The batching and discharging process of the system works as follows: when the weighing module detects that the material is in place and determines whether the measurement of the hopper scale by the weighing module reaches the set value, the discharging can be carried out.

Mixing Weighing dosing system based on PC and precise quantitative dosing is a set of machine, electricity, signal processing and dosing in one of the technical equipment, electrical part is mainly composed of weighing sensor, weighing instrument, programmable controller (PLC), frequency converter, 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 display 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 dust-free automatic feeding system is controlled by PLC timing. The mixer is always stirring. During stirring, liquid is added quantitatively. The material bin must be discharged when the material door of the temporary storage hopper is closed (if the temporary storage hopper is equipped with a weighing scale) and the scale is empty. After the material and miscellaneous bin is closed in place, the temporary storage hopper begins to discharge materials. The external storage tank and the in-plant material silo start to feed materials to the screw after a delay. The amount of material fed is controlled by the opening degree of the material door. The start and stop are controlled according to the start and end of material discharge in the temporary storage hopper. All controls are implemented by the PLC for interlocking control, and the PLC controls the sequential start and stop.

The Measurement feeding system is a complete set of automation equipment that realizes dynamic weighing and batching control through electrical control management and visualization man-machine software configuration. The electrical control part of the system adopts Siemens PLC, which is programmed and controlled according to the production requirements; the software adopts human-machine configuration, which controls the weight and flow of the materials loaded into the weighing hopper according to the process requirements through the monitoring system and the PLC program, thus realizing the precise measurement and dosage. The weighing system has strong stability and high cost performance, and can provide accurate measurement data and control means for production control and management of various industrial sites.

The Constant pressure feeding system is mainly used in plastic injection, extrusion or hollow process where a variety of raw materials are mixed according to weight ratio. The setting data will not be lost after the power is cut off by EEPROM, no battery is used; Use the human-machine interface status display touch keyboard data input, more convenient operation, but also can store a large number of formula data (500 groups); High speed and high precision AD grab weight faster and more stable; All the boredom is evenly mixed after gravity measurement, which can strictly control the accuracy. Check the weight data and the selected raw materials to ensure the precision and accuracy of the mix.

The pneumatic batching system adopts positive and negative two-way tracking, which further improves the tracking accuracy. After the batching operation, the weighing module constantly detects and tracks the position of the micro-switch to detect the machine, and after the signal is sent to the PLC through the program calculation, the positive and negative tracking of the motor is controlled by the PLC output, and the error of the packaging materials in the production process is found in time and accurately compensated and corrected, avoiding the waste of packaging materials. If the detection can not meet the technical requirements after tracking the predetermined number of times, it can automatically stop for inspection to avoid the generation of waste products.
