Spiral weighing Feeder (spiral scale, cutter scale) is a specialized batching equipment used for continuous weighing, batch feeding, and batching of various powdered and bulk materials. The weight signal of the materials in the spiral and the speed signal of the spiral operation are transmitted to the weighing instrument together, and the instantaneous flow rate of the materials and the cumulative output of the materials are automatically calculated. Through continuous comparison between the set flow rate and the actual material flow rate, the speed of the metering spiral operation is constantly adjusted, so that the material flow rate can always be stabilized at the set flow rate. The weighing conveyor adopts an advanced feedforward regulation system control system, which continuously adjusts the speed of the powder balance lock feeder according to the set feeding amount measurement, and achieves very accurate, stable, and continuous feeding. The feeding station adopts an advanced feedforward regulation system control system, uses a powder balance lock feeder to ensure stable feeding, and adopts dual control functions for simultaneous adjustment The powder balance lock and measuring screw have improved the measurement accuracy. Adopting large feed inlet, variable diameter, variable distance, and overflow outlet to ensure uniform sinking of materials, stable control, no collapse of the warehouse, no accumulation of materials, and no material channeling. Adopting high-precision digital Weighing modules and digital transmission technology, it has a simple and adjustable circuit Segmented components, high resolution, no signal attenuation, strong anti-interference. The controller adopts touch display technology, with graphical display in both Chinese and English, guided operation mode, simple operation, and no need for memory. Can connect to 485 communication, CAN communication, DCS, PLC and other interfaces. Using GPRS wireless data transmission function, it can provide functions such as SMS reporting, remote diagnosis, and scale calibration.

The weighing and batching machine includes a bracket and a material cylinder fixed on the bracket. The opening of the material cylinder is downward, and a feeding mechanism is provided below the material cylinder. A precise weighing device is provided below the feeding mechanism, and an electronic weighing scale is provided on the precise weighing device for placing the material to be weighed; The feeding mechanism is equipped with a feeding port and a discharging port. The feeding port is connected to the opening of the material cylinder through a pipeline, and the discharging port is located above the weighing scale. The feeding mechanism sends the material in the material cylinder to the discharging port through the feeding port and lands it on the weighing scale; The precise weighing equipment is connected to the control system, and the control system controls the feeding amount of the feeding mechanism through the weight of the material measured by the precise weighing equipment. The feeding mechanism includes a feeding sleeve with one end closed and the other end open. If a cover can be fixed at one end of the feeding sleeve, the feeding sleeve is inserted into the transmission shaft from the open end. The transmission shaft is fixed with a feeding screw at one end of the feeding sleeve, and the feeding screw is fixedly connected to the transmission shaft through a pin. The feeding screw is coaxially arranged with the transmission shaft, and the outer circumferential surface of the feeding screw is matched with the inner circumferential surface of the feeding sleeve. The end face of the feeding screw is pressed against the closed end face of the feeding sleeve. The feeding and discharging ports of the feeding mechanism are set on the circumference of the feeding sleeve. The feeding screw is threaded along the circumference, and the thread extends from the feeding port to the discharging port. The transmission shaft is connected to the driving device at one end outside the feeding sleeve, and the driving device drives the driving shaft. Rotate around the axis; The control system controls the speed of the transmission shaft through the driving device.
