DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe the detailed embodiments of the present utility model with reference to the drawings in the specification.

[0026] Refer to Figures 1-4, which is an embodiment of the present utility model, provides a bottom-flushing degassing packaging machine. Such a bottom-flushing degassing packaging machine includes a frame 1, two operation platforms 2, a conveyor line 3, a control cabinet 4, and a blanking pipe 7. The frame 1 is located between the opposite faces of the two operation platforms 2. The conveyor line 3 passes through the inner cavity of the frame 1. The blanking pipe 7 is inserted and installed in the middle of the top of the frame 1. Chain lifting components 5 are installed at the four corners inside the frame 1. The chain lifting components 5 are existing mature technologies, so they will not be elaborated here. A lifting frame 6 is fixedly connected between the movable ends of the four chain lifting components 5. The chain lifting components 5 drive the lifting of the ton bag, reducing the drop between the discharge end of the blanking pipe 7 and the bottom of the ton bag, thereby playing a role in reducing dust during blanking;

[0027] A filling port assembly 8 is provided at the bottom of the lifting frame 6, and the discharge end of the blanking pipe 7 is located inside the filling port assembly 8. A fixing frame 16 is fixed on the upper side of the outer end of the filling port assembly 8. Hook assemblies 10 are installed at the four corner ends of the fixing frame 16. The hook assemblies 10 are existing mature technologies, so they will not be elaborated here. A clamping assembly 9 for clamping the packaging bag is installed on one side of the outer wall of the filling port assembly 8. The clamping assembly 9 is an existing mature technology, so it will not be elaborated here.

[0028] Multiple measures are used in combination to achieve the purpose of reducing dust spillage and reducing the gas content, avoiding environmental pollution and dust spillage, and achieving high-precision packaging.

[0029] A metering assembly 11 is installed at the top of the lifting frame 6. A weighing end of the metering assembly 11 is fixedly provided with a metering frame 13, and the metering frame 13 and the fixing frame 16 are fixedly connected by columns. The metering assembly 11 weighs the weight inside the ton bag and will automatically stop after the filling reaches the metering weight.

[0030] A packing seal assembly 12 for sealing the blanking pipe 7 is provided in the middle of the inner cavity of the metering frame 13. The blanking pipe 7 passes through the inner cavity of the packing seal assembly 12 and is in a movable connection state with the packing seal assembly 12. The packing seal assembly 12 is an existing mature technology, so it will not be elaborated here. When the chain lifting component 5 lifts the lifting frame 6 for lifting and lowering, the blanking pipe 7 and the filling port assembly 8 are in a relative motion state. The packing seal assembly 12 plays a sealing role on the blanking pipe 7, further reducing the powder spillage.

[0031] An air extraction chamber 14 for the blanking pipe 7 to pass through is installed at the top of the packing seal assembly 12. A flexible connection 15 is installed between the bottom end of the air extraction chamber 14 and the top end of the filling port assembly 8, and the blanking pipe 7 passes through the inner cavity of the flexible connection 15. An air extraction chamber 14 is provided above the flexible connection 15. The dust raised during blanking will be extracted when passing through the inside of the air extraction chamber 14, reducing the amount of powder leakage.

[0032] The filling port assembly 8 includes a filling port pipe 81, and the clamping assembly 9 is fixed on one side of the outer wall of the filling port pipe 81. A flange is welded to the top of the filling port assembly 8. Inflation interfaces 82 and exhaust interfaces 84 are respectively welded at the inlet and outlet on both sides of the outer wall of the filling port pipe 81. During the discharging process, the air inside the ton bag is also pumped out to reduce the air inside the ton bag and enable it to exhaust quickly.

[0033] A dust suppression baffle 83 is welded inside the filling port pipe 81, and the longitudinal section of the dust suppression baffle 83 is in a "Y" shape.

[0034] A rubber expansion tube 86 is fixed at the lower end of the outer wall of the filling port pipe 81. An inflation chamber 88 is fixed on one side of the inner wall of the filling port pipe 81. A communication port 89 for connecting the inner cavity of the inflation chamber 88 and the rubber expansion tube 86 is opened below one side of the filling port pipe 81. An injection port 87 communicating with the inner cavity of the inflation chamber 88 is opened above one side of the filling port pipe 81. An injection pipe 85 is welded at a position on the outer wall of the filling port pipe 81 opposite to the injection port 87. When inflating into the injection pipe 85, the gas enters the inner cavity of the inflation chamber 88 through the injection port 87. The gas in the inner cavity of the inflation chamber 88 enters the inner cavity of the rubber expansion tube 86 through the communication port 89, causing the rubber expansion tube 86 to inflate and expand. When the rubber expansion tube 86 and the clamping assembly 9 are used in combination, the bag mouth of the ton bag is fully tightened and sealed, so that dust will not spill out from the bag mouth at all.

[0035] During use, an operator hangs the ton bag on the hook assembly 10, puts the bag mouth over the discharging end of the filling port assembly 8, and controls the clamping assembly 9 to clamp the bag mouth tightly. The filling port assembly 8 is used to inflate and form the ton bag internally. The chain lifting assembly 5 is used to lift the ton bag. The discharging end of the blanking pipe 7 gets closer and closer to the bottom of the ton bag as the chain lifting assembly 5 rises, and then starts to discharge materials;

[0036] The chain lifting assembly 5 also descends during discharging. The chain lifting assembly 5 drives the lifting and lowering of the ton bag, reducing the height difference between the discharging end of the blanking pipe 7 and the bottom of the ton bag, thereby reducing dust during discharging;

[0037] The weighing component 11 weighs the weight inside the ton bag. After the filling reaches the weighing weight, it will automatically stop. Then, an operator closes the bag mouth, releases the fixing of the hook assembly 10 on the ton bag, and the ton bag filled with materials falls on the conveyor line 3. The product is conveyed to the next process through the conveyor line 3.
