The automatic gear Batching system consists of a weighing module, a junction box, a weighing instrument, a wiring cabinet, and a PLC control cabinet. The main hardware consists of two computers, a high-performance microcomputer controller, a human-machine interface, a high-speed and high-precision weighing unit, and internationally renowned low-voltage electrical appliances. Combined with self-developed professional control software, it realizes the batching system for chemical liquid production; At the beginning of each ingredient cycle, the difference between the previously set feeding amount and the actual feeding amount is calculated as the compensation value for the feeding amount set for this cycle, in order to eliminate the cumulative error of each scale feeding amount. The feeding system automatically adds two or more materials into the reaction tank in a certain weight ratio, and the stirring motor is turned on and off after a specified time. When the mixing motor is turned off, the material is prepared to be sent out to the material tank under the drive of the gear pump. The weight generated by the weighing module and weighing instrument is amplified by the weight signal generated by the weighing instrument and then collected by the PLC and computer. When the predetermined weight is reached, the PLC drives the closure of the pneumatic valve, and the batching process is completed in one go. The process of automatic discharge after mixing to meet the predetermined requirements. At the beginning of each ingredient cycle, the difference between the previously set feeding amount and the actual feeding amount is calculated as the compensation value for the feeding amount set for this cycle, in order to eliminate the cumulative error of each scale feeding amount.

The main hardware of the weighing control system consists of two computers, a high-performance microcomputer controller, a human-machine interface, a high-speed and high-precision weighing unit, and internationally renowned low-voltage electrical appliances. Combined with self-developed professional control software, it realizes the batching system for chemical liquid production; Set up two working modes: "automatic" and "manual". "Manual" work is to complete a certain control step separately, such as "feeding", "mixing", and "discharging" separately. The "pause/continue" button is allowed to pause, and parameters can be modified in the paused state; The 'automatic' task is to complete a complete cycle of control, including feeding, mixing, discharging, and other processes. During the 'automatic' operation, only the 'pause/continue' button is allowed to be valid, and the 'manual' buttons are invalid and parameters cannot be modified; Having an immediate stop function: When the "stop" button is activated, any control process will stop and return to the weight display state; Equipped with zero setting function: Pressing the "zero setting" button while weighing can reset the displayed value to zero. If it exceeds the zero setting range, it cannot be reset and an error message will be displayed; Equipped with a tare function: Pressing the "tare" button while weighing will deduct the displayed weight as tare weight, and pressing the "tare" button again will restore the original displayed weight.

The weighing and batching machine adopts a weighbridge for measurement, with multiple hopper scales at the top of the weighbridge and a feeding mechanism built into the hopper scales that can be vertically lifted and lowered; The feeding mechanism adopts opposite sliding grooves set on both sides of the hopper scale, as well as sliding blocks embedded in the sliding grooves and arranged from the top to the bottom of the sliding grooves, measuring rods, and springs. The hopper scale also has a feeding bag inside, which is fixedly connected to the sliding block and slides along the direction of the sliding groove through the sliding block. There is also a card knife inside the hopper scale and located at the bottom of the feeding mechanism. The direction of the card knife's blade is facing the feeding bag. The weighing frame has a flow channel inside, which has multiple feeding ports connected to the bottom of the hopper scale, as well as a discharge port. The flow channel near the discharge port is equipped with a stirring device, and the bottom end of the stirring device is equipped with a receiving groove, which faces the weighing scale. Set up and form a material retrieval channel on the side. The bottom of the feeding bag has a fragile opening, which is driven by a slider and slides towards the bottom of the hopper scale. The fragile opening is cut open by a card cutter for feeding. The hopper adopts a material retrieval bin, which can be inserted into the material retrieval channel and coincides with the material receiving groove. The upper end of the weighing scale is also equipped with a motor, which drives the mixing device to rotate through the shaft, crushing and mixing the materials.
