The electronic scale of the oil drum handling vehicle adopts a clever combination of movement and electronic scale weighing. It can be weighed during handling or unloading. It is composed of a hydraulic handling mechanism and weighing components. The electric hydraulic scale platform can rise and fall, and the vehicle can be moved horizontally by manual push. Improve the professional production level of oil drum vehicle handling and measurement, expand the production scale of enterprises, and enhance the overall survival ability and competitiveness.

The real-time and TCP/IP-based communication on a line is realized by wireless PROFINET communication, and the controller, distributed I/O system and other Ethernet-based devices can be integrated into a common communication framework. It really realizes the synchronization of weighing and handling, and the data information of each weighing can be displayed automatically on the weighing instrument, which truly ensures the dual-purpose function of one machine and completes the weighing and transportation at the same time.

The weighing of stacker truck is a weighing and measuring instrument for weighing the loaded materials during the loading process of loading equipment, which is developed for mobile weighing. The handling and weighing of goods are combined into a whole, and the handling and weighing are completed at one time, thus avoiding the waste caused by extra idle driving, saving time to the maximum extent and improving work efficiency. Can provide the cumulative value of the weighed material and print list.

The weighing sensor uses the compensation network based on radial basis function neural network to complete the nonlinear error compensation of the sensor; In the lower limit region, a digital filter is used to complete the nonlinear error compensation. In the middle area, the weighing sensor does not compensate, and at the same time, the selection of subsection compensation is completed by using the adaptive selection network. The piecewise compensation model of nonlinear error is established to obtain good compensation effect.

Weighing sensor is a kind of mass (weight) measurement method that converts mass (weight) into electricity through the stressed structure. The output electric quantity signal and the input quality (weight) signal have a single value linear correspondence; It has the required accuracy and high sensitivity; It has good frequency response characteristics and less inertia; Little influence on the state of the weighed object; Able to work in poor environmental conditions; Good stability, reliability and long service life.

The Instruction Dosing System utilizes PLC as the central control area to complete the whole process of weighing and feeding. The PLC central control area sends out a signal to start the corresponding solenoid valve to inject the liquid into the reaction kettle, and at the same time, the weighing module starts to work. When the amount of liquid in the reaction kettle increases to the same value as the weight set by the quantitative setting finger, the central control area receives the action signal from the weighing module, and immediately closes the solenoid valve for adding liquid and stops adding liquid. Automatically start the stirring switch, the control area sends out the instruction to start the corresponding solenoid valve of the mixer and the timer set by the program starts to time, the mixer stirs the solution evenly; when the timer time reaches the set value, the control area sends out the instruction to close the solenoid valve and stops the stirring.

The hardware of the temperature control system mainly consists of a frequency converter, temperature control, and PLC process control components. After receiving the speed and torque signals from the PLC, the frequency converter controls the frequency converter drive to set the corresponding speed and direction to make the motor operate. At the same time, it transmits the feedback signal back to the PLC to monitor whether the armature temperature, speed, and torque exceed the set values. The PLC process control is based on the on-site signals to control the operation of the feed-in, main unit, conveyor, and temperature unit, and provides corresponding working status displays for the operators to monitor.

The human-machine interface of the Spiral feeding system is developed based on the operating system, which can meet the requirements of monitoring and controlling the production process as well as archiving and processing the production data. The user interface drawn by WinCC is simple and easy to operate with a good human-machine interface, which can dynamically display the operation status of various equipment on the site and the various parameters of the dosage operation. The operator can also flexibly control the starting and stopping of the field equipment and change the operating parameters of the dosage according to the needs.

The adjustment batching system sends a full material signal to the PLC through the weighing module. The PLC then controls the conveyor to stop the screw. When the material reaches the minimum storage level, the weighing module sends a signal to start the conveyor's screw rotation. The step motor drives the conveying pipe to rotate, enabling the switching of material transportation between different branches. The step motor rotates the rotating support frame, thereby driving the screw conveying pipe to rotate and connecting it to one of the discharge outlets. This achieves the functions of arbitrary switching of the system distribution machine's conveying pipeline, automatic opening and closing of the electric valve, automatic adjustment of the screw conveying discharge speed, and automatic starting and stopping of the screw.
