When the position on the machine base 1 is sensed When the device 12 detects that the weighing component 7 is rotated in place, if the weight measured by the weighing component 7 also meets the requirements, the telescopic bag press 58 retracts to release the packaging bag. Under the action, the weighing component 7 is turned over and separated from the weighing component 7 to enter the next process; if the weighing component 7 detects that the weight of the powder entering the packaging bag is not enough, the packaging bag continues to rotate on the weighing component 7 and the feeding component 4 continues The material is conveyed until the required weight is finally reached. When it passes through the position sensor 12 again, the packaging bag is detached.
