The automatic weighing and Filling machine uses weighing instruments to collect data through Weighing modules and perform calculations to control the execution components, achieving automatic weighing and unloading of materials for filling. The measuring filling machine is a weighing instrument that controls only one measuring bucket, consisting of a weighing instrument, material preparation bucket, measuring bucket, discharge bucket, weighing sensor, filling machine, bracket, etc. The material is fed into the preparation bucket by the feeding motor, and then enters the measuring hopper from the preparation bucket. The weight of the material in the measuring hopper is collected by the weighing module through A/D conversion by the weighing instrument. The weighing instrument continuously collects data and calculates the current feeding speed of the measuring hopper based on the collected time difference. Then compare the pre-set value with the weight of the material in the current measuring bucket and calculate the time needed to continue feeding. The Liquid filling machine continuously collects data and makes judgments to calculate the new feeding speed and required feeding time. In addition, the feeding port size of the material preparation bucket and the measuring hopper is controlled by a weighing instrument, which can ensure the accuracy of the measurement. The weighing instrument controls the size of the feeding port of the ingredient bucket. At the beginning, the feeding port is the largest (large feeding). When the weight of the material in the measuring bucket approaches 70%~80% of the set value (specifically set by the software part of the weighing instrument), the feeding port shrinks partially (medium feeding). When it approaches 80%~95% (specifically set by the software part of the weighing instrument), the feeding port shrinks to the smallest feeding port (small feeding). Finally, when the weight of the material in the measuring bucket plus the weight of the material falling from the air reaches the set value, the feeding port of the material bucket is closed and the weighing is completed. The measuring bucket can be unloaded into the filling bag for sealing.
