The wireless weighing fork is equipped with a weighing console on the electric forklift, and the weighing instrument is installed on the console. The data lines installed with weighing sensors at the lower parts of the two fork support legs are connected with the digital instrument. When the elastic body adopting digital weighing is subjected to force from the stress direction (such as the gravity of goods), the elastic body generates corresponding micro deformation, which is transmitted to the digital weighing instrument through the force transmission mechanism, and the gravity signal output by the sensor is amplified and filtered. It is sent to an A/D converter to be converted into a digital signal, and the microprocessor calculates the weight value according to the mechanical mathematical model. When the forklift mast is in a vertical state, the weighing data is prompted to be read, and the digital weighing LED displays the results. The real-time data is uploaded to the computer control room by the weighing instrument through wireless.
020-34563445Electric forklift Electronic scale refers to all kinds of wheeled handling vehicles that carry out loading and unloading, weighing, stacking and short-distance transportation of pallet goods. ISO/TC110 is called electronic scale industrial vehicle. Belonging to a material handling and weighing machine. Widely used in stations, ports, airports, factories, warehouses and other national economic departments, it is an efficient electronic scale weighing equipment for mechanized loading and unloading, metering, stacking and short-distance transportation. The forklift electronic scale is a widely used weighing machine for lifting, loading, unloading and transportation, which is widely used for loading, unloading, stacking, weighing and short-distance transportation of finished goods in ports, docks, warehouses, freight yards and industrial and mining enterprises.
The forklift electronic scale is a new type of electronic weighing technology developed by combining modern microelectronics technology and microcomputer technology. The sensor body is composed of four weighing elastomers on the base, and the strain gauges attached to it are slightly deformed, which leads to their resistance changes. In order to measure the resistance changes, the weighing sensors are connected into a bridge circuit, and the bridge is balanced when the sensor has no external force. When the sensor is acted by external force, the terminal voltage of CD is not equal. The voltage change is measured by the amplifier circuit and converted into the corresponding quality value for display.
In order to ensure the measurement accuracy of forklift weighing in various environments, linear compensation, zero compensation and temperature compensation, as well as anti-corrosion treatment of sensor surface are generally added to the bridge of forklift weighing strain gauge. At the same time, in order to ensure the accuracy of remote excitation of the sensor, two wires are generally output to the weight transmitter or weighing terminal at the excitation ends of the strain gauge to calculate the loss compensation of the excitation voltage during long-distance transmission.
The forklift electronic scale adopts sealed junction box, which is dust-proof and moisture-proof to ensure reliable signal transmission. The weighing instrument adopts special industrial process controller, and communicates with the central control room through RS-485 bus, which can be controlled independently and online by PLC. It is composed of computer, weighing module and peripheral equipment, which serves as the man-machine interface of the whole system. Complete all system parameter setting, process monitoring and data recording.
