[0030] See Figures 1-9 This utility model provides a ton bag unloading station, comprising a receiving tray 1, an operating chamber 2, a dust removal box 4, and a mixing chamber 7, which are arranged from top to bottom and connected in sequence.

[0031] like Figures 1-4 The receiving tray 1 is funnel-shaped. Two striking balls 3 and two power cylinders 10 are installed on the receiving tray 1. The power cylinders 10 are installed on the lower surface of the receiving tray 1 through the mounting bracket. The piston rod of the power cylinder 10 passes vertically through the wall of the receiving tray 1 and is connected to the striking balls 3. The striking balls 3 converge toward the center of the receiving tray 1 in an inclined upward manner and make reciprocating motion. The striking balls 3 are evenly distributed on the receiving tray 1 with the lower opening of the receiving tray 1 as the center.

[0032] The lower end of the receiving tray 1 is open and connected to the operating chamber 2. Two operating ports are opened on the side wall of the operating chamber 2, and two corresponding operable operating chamber doors 11 are installed. Figure 4 A support frame 25 is also installed on the lower surface of the receiving tray 1 to support the receiving tray 1. The support frame 25 is hinged to the cylinder of the gas spring 26. The piston rod of the gas spring 26 is hinged to the operating chamber door 11. The gas spring 26 is used to support the operating chamber door 11 and keep the operating chamber door 11 in a closed state. A semi-circular opening 27 is opened at the lower end of the side wall of the operating chamber 2. A ring valve is installed at the semi-circular opening 27 of the operating chamber 2. The ring valve is existing technology and is commonly used in powder mixing equipment. The ring valve has an opening in the middle and can control the opening and closing, the size of the opening, and lock it.

[0033] like Figure 1 , 5 6. It also includes a dust removal system, which includes a first dust removal chamber 12, a second dust removal chamber 13, an exhaust fan 5, and a dust bag 6. The first dust removal chamber 12 is located on the upper side inside the dust removal box 4. The first dust removal chamber 12 has three dust removal chamber through holes 28. The first dust removal chamber 12 is connected to the dust removal box 4 through the dust removal chamber through holes 28. The first dust removal chamber 12 is connected to the second dust removal chamber 13. The dust bag 6 is detachably installed between the first dust removal chamber 12 and the second dust removal chamber 13. The second dust removal chamber 13 is connected to the exhaust fan 5.

[0034] like Figures 5-6An internal air blowing pipe 15 is installed in the second dust removal chamber 13. The internal air blowing pipe 15 is connected to five air blowing ports 14. The air blowing ports 14 face the dust removal bag 6 and correspond to each other. The internal air blowing pipe 15 is connected to the external air blowing pipe 16. The external air blowing pipe 16 passes through the second dust removal chamber 13 and is connected to the control valve 17 and the compressed air tank 18 located outside.

[0035] See Figures 5-6 When the exhaust fan 5 is operating, the control valve 17 remains closed, and no gas is ejected from the air outlet 14. The exhaust fan 5 creates negative pressure in the first dust removal chamber 12 and the second dust removal chamber 13, causing air and airborne powdery materials to flow through the dust collection box 4 into the first dust removal chamber 12. The dust collection bag 6 in the first dust removal chamber 12 separates the powdery materials from the air. When the exhaust fan 5 stops operating, the control valve 17 can be opened, allowing compressed gas from the compressed air tank 18 to be blown out through the control valve 17, the external air pipe 16, the internal air pipe 15, and the air outlet 14, removing the powdery materials from the dust collection bag 6 and ensuring that the dust collection bag 6 maintains good filtration performance.

[0036] The bottom of the dust collector 4 is open and a filter screen 19 is installed to filter out powdery materials and foreign objects that have turned into lumps. The side of the dust collector 4 is open and a switchable dust collector door 20 is installed. When the dust collector door 20 is opened, small and medium-sized packaging bags can be poured into the dust collector 4. A locking device is installed on the dust collector 4 to seal and lock the dust collector door 20 when it is closed. The dust collector door 20 is provided with a viewing window for observing the working conditions inside the dust collector 4.

[0037] like Figures 7-9 The mixing chamber 7 is equipped with rotating mixing blades 8. The mixing chamber 7 is an irregularly shaped chamber. The mixing blades 8 rotate in contact with the inner wall of the mixing chamber 7. The mixing blades 8 are roughly U-shaped. The shape swept out by the rotating mixing blades 8 is roughly frustum-shaped. A material collection box 21 is set at the bottom of the mixing chamber 7. When the mixing blades 8 rotate to the bottom of the mixing chamber 7, they push the powdery material into the material collection box 21. The material collection box 21 is connected to a suction pipe 22. The suction pipe 22 is connected to an external suction machine to suck away the powdery material in the material collection box 21.

[0038] The rotating shaft of the stirring blade 8 is set at an angle, and the stirring motor 9 is connected to the rotating shaft of the stirring blade 8 through a reducer to transmit power.

[0039] The mixing chamber 7 has an opening on its body and a corresponding mixing chamber door 23 is installed. A rotary level gauge 24 is installed on the mixing chamber door 23 to detect the height of the powdery material in the mixing chamber 7.

[0040] When unloading large-sized ton bags, refer to Figure 2The staff closes the dust collector door 20, operates the aperture valve at the semi-circular opening 27 of the operating chamber 2 to open the aperture valve, and turns on the exhaust fan 5 to create airflow from the receiving tray 1, operating chamber 2, and dust collector 4 to the first dust collector chamber 12; the lower end of the ton bag 29 is equipped with a ton bag discharge port 30, which is sealed tightly with a rope 31. The ton bag 29 is hoisted onto the receiving tray 1 and slowly lowered. The ton bag discharge port 30 is located in the operating chamber 2 and opened. On the side of the operating compartment 2, through the operating compartment door 11, the operator inserts the lower end of the ton bag discharge port 30 downwards through the opening of the aperture valve. The operator then operates the control handle of the aperture valve to narrow the opening, locking the ton bag discharge port 30. After releasing the binding rope 31, the operating compartment door 11 is closed. The control handle of the aperture valve is located outside the operating compartment 2. Operating the control handle of the aperture valve opens the aperture valve and controls its size, thereby controlling the discharge speed of the ton bag discharge port 30. If unloading of the ton bag 29 needs to be stopped midway, the operator operates the control handle of the aperture valve to close and lock the ton bag discharge port 30. The operator then opens the operating compartment door 11, uses the binding rope 31 to secure the ton bag discharge port 30, opens the aperture valve opening, and uses hoisting equipment to lift the ton bag 29 upwards.

[0041] During the unloading process, the power cylinder 10 controls the striking ball 3 to reciprocate, patting the ton bag and promoting faster falling of the powdery material in the ton bag.

[0042] During the unloading process, the exhaust fan 5 operates to suck away and remove the powdery material scattered in the air of the dust collector 4. After the unloading is completed and the powdery material scattered in the air of the dust collector 4 is cleaned, the exhaust fan 5 is turned off. The mixing blades 8 in the mixing chamber 7 mix the powdery material. After the mixing is completed, the external suction machine sucks away the powdery material in the mixing chamber 7 through the connected suction pipe 22 and the material collection box 21.

[0043] When unloading small and medium-sized packaging bags, the staff opens the dust collector door 20 and turns on the exhaust fan 5. The powdery material from the small and medium-sized packaging bags is poured into the dust collector 4 through the opening of the dust collector door 20. The powdery material enters the mixing chamber 7 through the dust collector 4. After the unloading is completed, the dust collector door 20 of the dust collector 4 is closed. After the exhaust fan 5 has sucked up and removed the powdery material scattered in the air in the dust collector 4, the exhaust fan 5 is turned off. The mixing blades 8 in the mixing chamber 7 mix the powdery material. After the mixing is completed, the external suction machine sucks away the powdery material in the mixing chamber 7 through the connected suction pipe 22 and the material collection box 21.

[0044] In summary, this utility model's ton bag unloading station features a receiving tray at the top for unloading large-sized ton bags. In the operating chamber, the outlet of the large-sized ton bag is connected to the aperture valve for easy control of the unloading speed. An opening on the side of the dust collector in the middle allows for unloading of small and medium-sized packaging bags. This utility model's ton bag unloading station has a wide range of applications, capable of unloading powdery materials from packaging bags of different sizes, and includes a dust removal system to prevent powdery materials from scattering into the working environment during unloading.
