The decentralized weighing batching machine can automatically or semi-automatically complete the processes of ratioing each raw material, weighing, loading the mixture, and distribution, until the required number of weighing/batching cycles for each batch is completed. At this point, the PLC performs a series of calculations and control operations. Next, the following operations will be carried out: calculating the next target value, calculating the target value of the raw materials, and automatically correcting parameters, etc. Relevant parameters will be displayed on the main screen of each raw material and the parameter setting window, which can be used as a control reference by the operator.

The weighing instrument converts the weight information received by the weighing module into a millivolt-level voltage signal and outputs it to the instrument. This signal is then amplified by an amplifier and converted into a digital quantity by an AD converter for calculation. After the calculation is completed, a series of data processing and analysis will be carried out, and various control signals will be generated. These signals are driven through multiple levels and ultimately control the solenoid valve to achieve the control process.

The weighing batching machine can be equipped with one, two or more Weighing modules according to specific circumstances. Each weighing batching machine samples using three weighing modules. Each weighing batching machine has an upper soft connection, a discharge door, a lower soft connection and a wall vibration device. Before receiving the material, the upper soft connection rises to align with the feed port; before discharging, the lower soft connection drops to align with the discharge port. After receiving and discharging, the upper or lower soft connection returns to its initial position, which can reduce the dust released into the air. During discharging, the wall vibration device vibrates the Weighing system to reduce the residue of the material in the bin and ensure the accuracy of weighing.

The Batching system refers to the entire process of transporting the material from the storage bin to the mixing bin. The storage bin is conveyed through a vibrating screen, while the mixing bin is conveyed through the batching machine. According to the specified material batching list, it is sent to the hopper scale for weighing and then discharged, and accordingly sent to the internal funnel of the bin. Each storage bin has a vibrating screen, which directly conveys the material to the weighing funnel inside the bin. When the material reaches the material bin, the door of the hopper is fixedly closed, and it is received by the top receiving valve, upper sealing valve, throttling regulating valve, and lower sealing valve through the distribution channel, and then evenly transported to the bin interior. The weighing batching machine controls the discharge speed of the screw conveyor based on the rate of weight decrease of the material to achieve quantitative batching. When the material in the feed scale reaches the lower limit of weighing, the screw conveyor discharges at the current speed, and at the same time, the material in the storage bin is rapidly lowered into the feed scale. When the filling reaches the upper limit of the scale, filling stops. Rapid feeding can shorten the feeding time and improve the accuracy and control precision of weighing. By controlling the fixed value of the volume of each stage of material, automatic batch control and the collection and transmission of a series of signals can be achieved during the production process, thereby achieving precise control of feeding.
