Screw conveyor has a powerful data management function and summary, industrial computer monitoring and PLC detection, calculation and control is the most advanced and most reliable industrial automation control mode. The average continuous trouble-free operation time of Siemens PLC can reach tens of thousands of hours, and is most suitable for strong interference, harsh environment of the industrial site, industrial control computer is also specifically designed for the industrial site, can run continuously, safely and reliably, and industrial computer is one of the best on-site measurement and control of the ideal choice.

The weighing conveyor feeds the measured value as an input signal into a calculating device with multiplication and integration functions. The belt feed detector, integrated controller and drive unit, the coal charging detector, belt feed detector and drive unit are installed as parts of the feeder, the loading detection unit consists of a bearing roll and two weighing modules, two weighing modules measure the mass (gravity) of the precision weight table and transmit the signal to the integrated controller, and the signal of each sensor is consistent with the previous data. The signal of another sensor is compared, thus testing the effectiveness of the signal, if the signal is effective, the signal is multiplied by the correction factor to obtain the actual mass per unit length of the belt.

Weighing conveyor adopts weighing controller technology and gravity weighing principle to design a continuous material flow weighing equipment. Combined with servo motor stacking and careful mechanical design, the weighing instrument and microcomputer are the control core, the piezomagnetic sensor is the weighing module, and the weighing instrument is the analog-to-digital conversion device. In addition to some auxiliary control circuit and power amplifier circuit of the weighing conveyor loading system, can be used for material measurement can also be used as a quantitative feeding equipment.

Weighing conveyors are ideal for high speed applications, with a large dimensional measurement range and processing efficiency to count packages and provide data for correct sorting. Flexible configuration according to different requirements of users. Used to measure the regular shape of the object transmitted on the raceway, installed above the raceway, no need to separate the transmission belt, the raceway can be bidirectional transmission, the front and rear objects can be placed together through the measuring head, increasing the total throughput.

Weighing conveyor is a kind of equipment that can carry out on-line dynamic weighing of materials. It is mainly composed of a belt suspended on the bracket, a weighing sensor and a control system.

Weighing conveyor through the weighing module installed under the conveyor, the weight of the material itself will act on the sensor when it passes through the measuring section of the conveyor, and then it will generate a millivolt signal, and at the same time, the speed sensor will provide a conveyor belt speed signal, and these two signals will enter into the weighing system at the same time and carry out the arithmetic operation, and then the weight data can be displayed.

Weighing conveyor will pass through the material on the belt, through the weighing scale frame under the load cell to detect the weight, the feeding controller will be the flow and set the flow rate for comparison, the output signal from the controller to control the frequency converter speed regulation, to achieve the requirements of quantitative feeding. It is an automatic scale that continuously weighs the bulk material on the conveyor belt without the need to subdivide the mass or interrupt the movement of the conveyor belt.

Weighing conveyor is from the weight of the material on the belt, the weighing signal and the speed signal of the belt running together transmitted to the microprocessor weighing controller, automatically calculate the instantaneous flow of the material. By continuously comparing the set flow rate and the actual flow rate, the speed of the belt is adjusted so that the actual material flow rate is kept at the set flow rate value.

The weighing conveyor is used for the quantitative feeding of bulk materials, the feeding process is a spiral rotating continuous feeding, the materials from the user feed bin or other feeding equipment will be transported and through the weighing bridge for weight detection; at the same time installed in the end of the speed sensing screw for speed detection; the detected weight signal and speed signal together into the weighing controller for calculus processing and display in tons per hour unit of instantaneous flow and cumulative amount in tons per hour. Instantaneous flow rate in tons per hour and cumulative flow rate in tons per hour are displayed.
