At the same time, the coordination of the electronic crane scale instrument controller 7 and the locking mechanism 9 further ensures the quantitative control of the raw material delivery, thereby improving the accuracy and efficiency of the raw material delivery.

[0028] The working principle of the above embodiment is:

[0029] (1) The operator first uses a forklift to transport the raw material ton bag 4 containing raw materials to the position for placing ton bags in front of the ton bag unloading equipment frame 1, and then starts the electric hoist 2 to move the electric hoist 2 to the top of the raw material ton bag 4 containing raw materials. Then, the raw material ton bag 4 is lifted by operating the electric hoist 2, and then the electric hoist 2 is driven to move, thereby moving the raw material ton bag 4 containing raw materials until it moves to a suitable position. Here, the raw material ton bag 4 is also driven to slowly descend by operating the electric hoist 2, so that the raw material ton bag 4 containing raw materials can smoothly approach the ton bag discharge port 5 and the raw material input port 8, until the ton bag discharge port 5 stops descending to the raw material input port 8.

[0030] (2) Then, the ton bag value of the electronic crane scale meter controller 7 is recorded, the value of the raw materials to be put in is calculated and the corresponding value is input into the electronic crane scale meter controller 7. Then, the operator opens the ton bag discharge port 5 and starts unloading. The electronic crane scale meter controller 7 monitors the weight change in real time until the preset value is reached. At this time, the electronic crane scale meter controller 7 can prompt the drive motor 902 to start, thereby driving the first worm 903 and the transmission wheel 905 to rotate, and then the second worm 904 can also rotate. Then, the worm wheel 908 can rotate to drive the threaded rod 907 to rotate, and the threaded sleeve 909 can move to drive the clamping plate 910 to move. At the same time, the slider 912 also moves with the clamping plate 910 moves until the two clamping plates 910 fit together, at which time the ton bag discharge port 5 can be clamped, and then the operator manually tightens the ton bag discharge port 5, and opens the clamping plate 910 again through the above steps, and can cooperate with the electric hoist 2 to lift the raw material ton bag 4 filled with raw materials to a certain height and run it to the position where the ton bag is placed, and then it is transported away by a forklift to complete a cycle. The device achieves accurate measurement of the weight of the raw materials through the coordinated use of the electric hoist 2 and the raw material ton bag 4, ensuring accurate weight delivery. At the same time, the coordinated use of the electronic crane scale instrument controller 7 and the locking mechanism 9 effectively ensures the quantitative control of the raw material delivery, thereby improving the accuracy and efficiency of the raw material delivery.
