Explosion-proof dispenser utilizes the analog input template in PLC to collect real-time data on the site, calculate the actual standard filling value according to the weight of each weighing system, and save the value of the converted value for calculation to minimize the fluctuation of the weight to facilitate the application of numerical values and PID loop adjustment to ensure the accuracy of the adjustment of the falling error. The PLC output is controlled by three ways of rationing, dosing and frequency giving to the on-site frequency converter. When the operator selects rationing on the operation screen, he only needs to input the total weight of filling and the rationing ratio of each sub-scale, and then the amount of discharging of each scale can be calculated automatically, and tracking adjustment can be carried out according to this discharging amount.
020-34563445Weighing and Filling machine is a kind of equipment that can automatically weigh and quantitatively fill different containers such as bags, bottles, cans and buckets according to their weight. It senses the weight of bags, bottles, cans and buckets through the Weighing system and controls the discharging accordingly to realize the quantitative filling. It is responsible for measuring the weight of bags, bottles, cans and buckets and controlling the amount of material supply and filling. According to the instruction from the weighing system, provide the corresponding material supply for filling. Responsible for accurate filling of supplied materials into containers such as bags, bottles, cans and buckets. Convey materials to be filled from storage area to filling area, or convey filled containers to sealing or packaging area. Monitors equipment operation and responds to malfunctions in a timely manner.
The weighing and distribution machine consists of programmable controllers and Electronic scales to form a two-stage computer control network, and the distribution system connects on-site weighing instruments, control computers, PLCs, inverters and other intelligent and fast processing equipment through field buses. PLCs are mainly responsible for detecting, displaying and alarming the faults of the automatic filling machine, and at the same time, outputting signals to inverters to complete the regulation of the rotational speed of the electronic scales. PLC is mainly responsible for fault detection, display and alarm of the automatic filling machine and output signal to the frequency converter at the same time.
Liquid filling machine adopts the most widely used PID regulation in industrial control for the actual control of weight, according to the weight deviation, using proportional, integral, differential calculation of the control amount, through the frequency converter to regulate the speed of electronic scales, adjusting the amount of feed to make it equal to the set value, to complete the filling process.
