The weighing platform with added materials adopts electronic scale for quantitative filling through a filling valve. The valve operates in a switch mode. The filling valve is driven by a dual-position cylinder. When the filling starts, all the filling valves are fully opened for rapid filling. When the set value is reached, the dual-position cylinder operates, and the filling valves are partially opened for slow filling to ensure the filling accuracy. When the set value is reached again, the dual-position cylinder operates, and the filling valves are closed.

The canned weighing system uses the weighing platform to control the filling weight of the materials and automatically achieves precise filling of the materials. When an empty bucket enters the filling area, the front and rear bucket stoppers are pushed out. The front bucket stopper blocks the subsequent empty bucket and maintains a certain distance from the empty bucket in the filling area. The rear bucket stopper positions the empty bucket in the filling area. After a few seconds, the roller conveyor stops running. The pallet lifts the empty bucket, and the weighing controller takes the weight of the empty bucket and performs weight removal processing. The pneumatic gate valve opens, and the empty bucket is quickly filled with the required amount.

The can material scale is composed of filling, sealing, boxing, palletizing, weighing equipment, as well as corresponding conveyor belts, supplemented by automatic control and automatic adjustment systems. When the four-liter buckets reach the feeding conveyor belt, the filling bucket separator separates the buckets and sends them to the fixed scale platform. Quantitative filling involves symmetrically configuring the pistons of the cylinder around the rotating material bucket. Each piston is connected to an axle through a connecting rod, and the 180-degree forward circular motion causes the piston to rise, while the 180-degree backward circular motion causes the piston to descend. When the piston rises, the material is controlled by the valve to be sucked into the bucket from the upper cylinder. When the valve connecting the piston cylinder and the filling gun is opened, the material is injected into the lower bucket.

The filling scale adopts a weighing system for monitoring. The interface design controls the rotation angle of the stepper motor to regulate the filling feed volume of the servo mechanism. The circular pulse distributor distributes the control pulses output by the programmable controller to the corresponding windings in accordance with the energization sequence of the stepper motor. Using PLC to control the stepper motor, the pulse distribution can be realized through software for filling, capping, boxing, palletizing, weighing equipment, and corresponding conveyance.

Liquid dispenser is a weighing system that integrates weight information collection, amplification, transformation, transmission, processing and display, and controls each sensor, relay, switch and solenoid valve through PLC program. It draws on advanced technology and techniques, and combines with its own long-accumulated experience to integrate inventory management, filling management, filling and weighing, process control, and product traceability into one.

The weighing and distributing machine is composed of stepping motor, gear pump, filling head, conveyor belt and electric control box. The electric part mainly includes stepping motor driving power supply, locating solenoid valve, counter, cylinder filling head, conveyor motor and corresponding control circuit, the filling machine mechanism is connected by the output shaft of the stepping motor and the driving shaft of the gear pump through the variable-speed speed deceleration. The stepper motor can be used as a power source for filling liquid, and also can be used to accurately control the number of revolutions of the gear pump by controlling the number of running steps of the stepper motor to achieve the purpose of accurate measurement.

Weighing filling machine is a weighing filling, filling control, discharge and other computerized production process control and data management as one of the integrated automated filling control system, liquid filling machine using Mitsubishi Q series PLC and Advantech industrial control microcomputer to set up a high-performance control platform.

Weighing filler consists of feeding pump, solenoid valve, pipeline and weighing system. When the liquid level of the reaction tank is lower than a certain position, the solenoid valve opens, and the liquid flows into the dosing tank through the feeding pump and pipeline, and the solenoid valve closes when the liquid reaches the liquid level height.

The weighing and filling line picks up the weight through the pressure weighing module, and amplifies and filters the picked up weight signal, then enters into the A/D converter for analog-to-digital conversion, and then sends it into the microcontroller to analyze and process the signal, and the result is outputted to the industrial control through the serial port of RS232C communication, and meanwhile, it makes the corresponding reaction and executes the corresponding operation according to the result of the signal.
