Belt scale consists of steel mechanical weighing frame, speed sensor, high precision weighing sensor, electronic belt scale manipulation display instrument panel, etc. It can carry out continuous dynamic measurement and verification of solid materials. It is a fully automated electronic scale that continuously weighs the bulk material in the conveyor belt without the need for quality segmentation or termination of the conveyor belt movement.
020-34563445The structure of the belt scale adopts the double-roller weighing form, the weighing frame is supported by high-precision cross torsion springs, and is equipped with automatic belt tensioning mechanism, which can automatically adjust the tension and position of the belt, standard weights and weighting hammers, etc. The belt weighs the material on the belt through the Weighing system. The material on the belt is pressed on the pressure sensor by the weighing rollers, in which the counterweight is used to balance the weighing mechanism, so that the belt has a pre-pressure when it is unloaded.
The main control part of the belt scale adopts PLO Programming Controller (PLC), which consists of CPU module, I/O module, high-speed counting module, AD/DA module and scanner module. the CPU is used for the main program control, a 16-point digital input module and a 16-point digital output module, which is responsible for the digital input and output control of the whole electronic belt scale, as well as the provision of input and output signals required for the linkage with the external machine. The two 16-bit analog inputs and two analog outputs of the NI04I are used for weight sampling, and the D/A is used for frequency control and for outputting a 4-20 mA current signal for the current instantaneous flow. The weight signal is converted into 4-20mA current signal by the transmitter and sent to NI04I: the speed regulation signal processed by the computer is sent to the frequency converter by NI04I: the coded pulses from the speed encoder are sent to the high-speed counter to get the running speed of the belt by PLC operation.
Weighing frame structure and components to break through the inherent technology, the actual use of precision breakthrough 0.2%, much higher than the average market level, and can be maintained for a long time. Adapt to all kinds of on-site use, especially for trade occasions that require precise settlement.
Selected materials and precision components, lean technology production, the use of direct load-bearing weighing frame, no leverage support, no moving parts, there is no wear and tear of the support point and rubber aging problems and other issues, continuous and stable operation.
Convenient transportation and installation, low maintenance; remote monitoring, timely repair of faults, remote one-button operation. The horizontal surface is small, the accumulation of dust is small, do not need to clean often, daily use is basically free of maintenance trouble.
