[0020] As an embodiment of the present invention, the inlet of the storage silo 1 is connected to the material source of the production line. A weighing device is installed inside the mounting cavity 22. The weighing device is a weighbridge 13. Four sets of fixing components are installed on the top surface of the weighing device. A ton bag 11 is placed on the top surface of the weighing device. The four sets of fixing components fix the ton bag 11 to the top surface of the weighing device. The fixing components include four sets of suspension brackets 10 installed on the top surface of the weighbridge 13. A spring rod 9 is installed on the top surface of each suspension bracket 10. The connecting end of the spring rod 9 is elastically connected to a hook 8. Four sets of lifting lugs 12 are connected to the outside of the ton bag 11. The lifting lugs 12 are hung on the hooks 8.

[0021] As an embodiment of the present invention, further, an outer sleeve 21 is fitted on the outer side of the discharge pipe 2 near its bottom end, and a sealing member is also installed on the outer side of the discharge pipe 2. The opening of the ton bag 11 is fitted on the outer side of the discharge pipe 2 and is located in the gap between the outer sleeve 21 and the discharge pipe 2. The sealing member drives the outer sleeve 21 to squeeze the opening of the ton bag 11. The sealing member includes a pair of cylinders 6 and a clamping frame 5 that are rotatably connected to the outer side of the discharge pipe 2 by hinges. The output end of the cylinder 6 and the clamping frame 5 are rotatably connected by hinges. The clamping frame 5 is L-shaped, and a pressure block 7 is installed on the free end of the clamping frame 5. The pressure block 7 squeezes the outer sleeve 21, and a sealing ring is installed on the inner wall of the outer sleeve 21 near its bottom end.

[0022] As an embodiment of the present invention, the air extraction component further extracts air from the gap between the outer sleeve 21 and the discharge pipe 2. The air extraction component includes a negative pressure fan 17 and a water seal tank 18 installed on the ground. A negative pressure extraction pipeline 20 is connected between the input end of the negative pressure fan 17 and the outer sleeve 21. An outlet pipeline is connected between the output end of the negative pressure fan 17 and the water seal tank 18. An exhaust pipeline 19 is connected to the top surface of the water seal tank 18. The negative pressure fan 17 is used to extract the air and dust discharged from the ton bag 11 by the material. The water seal tank 18 can wash away the dust.

[0023] As an embodiment of the present invention, the bottom opening of the storage silo 1 is connected to a discharge pipe 2, and the discharge pipe 2 is connected to a control component. The control component is used to control the flow of materials in the discharge pipe 2. The control component includes a manual slide gate valve 3 and a pneumatic slide gate valve 4 connected to the discharge pipe 2. The pneumatic slide gate valve 4 is located below the manual slide gate valve 3. The manual slide gate valve 3 facilitates isolation and downstream maintenance. The control component also includes a control cabinet 14. A weighing display 16 is installed on the surface of the control cabinet 14, and an analog-to-digital converter 16 is installed on the bottom surface of the weighbridge 13. The control cabinet 14 receives the weight weighed by the weighbridge 13 after conversion by the analog-to-digital converter 16 and displays the result on the weighing display 16. At the same time, when the weight displayed on the weighing display 16 reaches the preset weight, the control cabinet 14, which controls the pneumatic slide gate valve 4, receives the instruction to control the pneumatic slide gate valve 4 to close and end the packaging. The control cabinet 14 is provided with an on / off operation button and an automatic / manual switching button to facilitate automatic and manual control of the ton bag device.

[0024] Specifically, the working principle of this material ton bag device is as follows: First, water is added to the water seal tank 18. Then, the four lifting lugs 12 of the ton bag 11 are suspended from the four hooks 8 of the suspension bracket 10. The opening of the ton bag 11 is then placed over the end of the discharge pipe 2. Next, the cylinder extension / retraction button on the control cabinet 15 is used to press the pressure block 7 against the outer sleeve cylinder 21, thereby causing the sealing ring of the outer sleeve cylinder 21 to press against the surface of the ton bag 11, completing the seal between the outer sleeve cylinder 21 and the surface of the ton bag 11. Then, the negative pressure fan 17 is started to evacuate the gap between the outer sleeve cylinder 21 and the discharge pipe 2. After opening the manual slide valve 3 and the pneumatic slide valve 4, the material in the storage silo 1 flows down the discharge pipe... 2. The material enters the ton bag 11. After the material enters, the weighbridge 13 weighs it. At the same time, the analog-to-digital converter 16 collects the data from the weighbridge 13 and converts it, then transmits it to the control cabinet 14. The program in the control cabinet 14 transmits the weight data to the weighing display 15 for display. When the material in the ton bag 11 reaches 1000kg, the program in the control cabinet 14 issues an instruction and closes the pneumatic slide valve 4, thereby completing the material unloading and packaging process. During the material unloading and packaging process, the negative pressure pipeline 20 sends the air and dust squeezed out of the ton bag 12 into the water seal tank 18 through the negative pressure fan 17. The outlet pipeline is inserted into the water seal tank 18 to wash the dust, and the clean air is discharged into the atmosphere through the exhaust pipeline 19.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a control cabinet. The control circuit of the control cabinet can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
