The discharge system is a production measurement equipment for continuous conveying, dynamic metering and feed control of various powder and loose granular materials. It integrates powder material feed transportation, weighing measurement and quantitative feed control, and is used for quantitative feeding of loose materials, detected weight signal and speed signal for calculus processing. Displays the instantaneous flow rate in tons per hour and the cumulative volume in tons.
020-34563445The batching machine is composed of feeding bin, screw machine, weighing module, vibration motor, trigger circuit and alarm circuit, etc. An industrial computer is responsible for the monitoring of multiple Electronic scales and batching production line. In the batching production process, the powder is evenly distributed on the spiral bin by each bin through the feed hopper, the spiral load weighing mechanism is detected by the weighing sensor, and the spiral speed is detected by the tonometry generator. The signal is rectified and amplified and then input into the control system. The control system is subjected to the load signal of the spiral motor and the speed signal of the belt. The actual feed rate is compared with the set feed rate constantly and the spiral speed is adjusted to make it accurately feed at the set feed rate, so as to achieve quantitative feed and measurement.
After the weight of the material and the speed of the spiral are detected and amplified by the load weighing module and the speed metering module, the gravity display with the weighing instrument as the core is displayed, and the conversion circuit becomes a digital pulse signal. The PC bus computer is used as the central controller to monitor the operation of the electronic scale and the batcher production line. After photoelectric isolation and isolation, the measured pulse signal is sent to the signal composed of weighing instrument as the core, which is controlled by the industrial computer to send it to the weighing instrument in batches for counting. The computer calculates and processes the material weight and spiral speed signals obtained by weighing instrument to obtain the actual flow rate of the batching. In order to improve the control speed of the whole system, and make full use of part of the circuit of the batching controller at low system cost, the actual flow rate obtained by the computer and the given flow rate are converted into an analog signal and then sent to the analog control circuit of the weighing controller, and the excitation coil current of the clutch is controlled by the trigger circuit to realize the speed control of the transmission spiral and the flow control of the batching.
