[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] Working principle: This filling machine adopts a bottom-filling filling method. The material is conveyed from the storage bin to the ton bag through the star-shaped discharge valve 2. The working process of the ton bag lifting mechanism 4 is as follows:

[0026] Bag opening preparation: The operator presses the control button, the lifting cylinder 43 extends, and the ton bag hook fixing frame 45 is lowered to the low position. The operator manually hangs the ton bag on the ton bag hook 46 and puts the bag opening into the filling port. The bag clamping air bladder 48 inflates and flexibly clamps the bag opening to ensure a seal.

[0027] Lifting and Tare: The lifting cylinder 43 retracts, and the ton bag is lifted to the set height. At this time, the weighing sensor 41 automatically deducts the weight of the ton bag and tare, and starts to monitor the weight of the material in real time.

[0028] Filling process: When the star-shaped discharge valve 2 is opened, the rare earth oxide material enters the ton bag through the filling port. The filling exhaust port 49 works simultaneously to discharge the gas in the bag or connect to a dust collection device to absorb dust.

[0029] Precise control: When the weighing sensor 41 detects that the material has reached the set weight, the control system immediately closes the star-shaped discharge valve 2 and stops the discharge.

[0030] Unloading and conveying: The lifting cylinder 43 extends again, lowering the ton bag to the pallet. The ton bag hook 46 automatically disengages, the bag clamping airbag 48 deflates and loosens the bag opening. After the bag opening is manually tightened, the ton bag flows to the next station through the ton bag conveyor line 3.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
