[0002] With the continuous progress of industrial automation, enterprises have higher and higher requirements for production efficiency and cost control. As a kind of efficient mechanized automatic packaging equipment, ton bag packaging machine is mainly used for packaging large-dose materials such as blocky, granular and powdery bulk materials, which can greatly improve the production speed, reduce the labor cost and save a lot of packaging cost for enterprises. After the material conveying is completed, the inflation bag needs to be inflated by air pressure to make the inflation bag deform to clamp and fix the ton bag, so as to ensure the subsequent ton bag sealing process. The existing air inflation structure usually installs a flange at the connection between the inflation bag and the inflation pipe to form a fixation, but as the inflation bag inflates, the flange mounting hole deforms to cause air pressure leakage, so that the ton bag cannot be fixed effectively, and the sealing effect is poor.

[0031] It should be noted that the telescopic sleeve body 1, the throat 2 and the variable diameter pipe 3 are provided with through holes, the through holes are consistent in width and are in communication with each other, and the inflatable inner container 13 penetrates the top of the expansion pipe 5 and is in communication with the through holes.

[0032] The telescopic sleeve body 1 is connected with an external feeding device, the conveyed material passes through the through holes of the telescopic sleeve body 1, the throat 2 and the variable diameter pipe 3 into the ton bag in the expansion pipe 5, the outer surface of the expansion pipe 5 is subjected to pressure and is deformed inwardly, thereby extruding and fixing the outer surface of the ton bag, and the plurality of connecting rods 6 and the welding plate 4 are fixed, thereby reserving installation fulcrums for subsequent limiting structures of the expansion pipe 5.

[0033] Referring to Figure 2 , Figure 3 The upper end surfaces of the expansion pipe 5 are provided with circular upper sealing plates 7, the opposite side surfaces of the two upper sealing plates 7 are provided with lower sealing plates 8, the lower sealing plates 8 are consistent in structure with the upper sealing plates 7 and are opposite in direction, the ends of the two upper sealing plates 7 and the lower sealing plates 8 away from the expansion pipe 5 are provided with protrusions, the abutment of the upper sealing plates 7 and the lower sealing plates 8 makes the two protrusions form an annular clamping groove, a T-shaped clamping block 15 provided with an embedded groove is arranged in the annular clamping groove, the side of the T-shaped clamping block 15 away from the annular clamping groove is fixedly provided with an expansion sleeve 9, the expansion sleeve 9 covers the upper sealing plates 7 and the lower sealing plates 8 at the upper and lower ends of the expansion pipe 5, thereby forming an inflatable outer container 10, and the opposite side surfaces of the two upper sealing plates 7 are welded with a plurality of welding flanges 11 (at least eight welding flanges 11), the middle portions of the plurality of welding flanges 11 are fixedly provided with screws, and the screws are screwed through the upper sealing plates 7 and the lower sealing plates 8 into the inflatable outer container 10.

[0034] It should be noted that the T-shaped clamping block 15 is consistent in material with the expansion sleeve 9, thereby improving the friction between the T-shaped clamping block 15 and the annular clamping groove and increasing the sealing property, one of the welding flanges 11 at one side of the top of the expansion pipe 5 is provided with a through hole in the middle portion of the screw, the through hole is in communication with the outside and the inflatable outer container 10, a gas conveying pipe 14 is arranged at the outlet of the through hole, the end of the gas conveying pipe 14 away from the inflatable outer container 10 is connected with an external gas pressure device, the outer surface of the expansion pipe 5 is provided with an annular limiting ring 12, the upper end surface of the limiting ring 12 is welded and fixed with the bottom portions of the plurality of connecting rods 6, and the diameter of the limiting ring 12 is consistent with the maximum deformation width of the expansion sleeve 9.

[0035] Two upper sealing plates 7, lower sealing plates 8 and the outer surface of the expansion pipe 5 are sealingly connected, cooperating with the T-shaped clamping block 15 and the annular clamping groove to form the integral sealing connection of the expansion sleeve 9, the upper sealing plate 7 and the lower sealing plate 8, and finally form the gas expansion outer container 10 as the input space reserved for gas pressure. At the same time, the gas expansion outer container 10 delivers gas pressure to form expansion, which applies a pushing force to the expansion pipe 5, extrudes and clamps the ton bag in the gas expansion inner container 13, facilitates the sealing process, and at the same time, the deformation of the expansion sleeve 9 applies a pulling force to the T-shaped clamping block 15, so that the T-shaped clamping block 15 is deformed and extruded in the annular clamping groove, thereby extruding the T-shaped clamping block 15 to the connecting port of the welded flange 11, thereby filling the connecting gap between the upper sealing plate 7, the lower sealing plate 8 and the welded flange 11, preventing gas pressure leakage.

[0036] The implementation principle of the gas expansion structure of the ton bag packaging machine according to the embodiment of the present application is as follows: when the device is used, the ton bag needs to be placed below the expansion pipe 5, and the opening of the ton bag is upwardly located in the gas expansion inner container 13, and then the external feeding device throws the material into the ton bag through the telescopic sleeve body 1, and the material falls into the ton bag through the through hole of the throat clamp 2 and the variable diameter pipe 3. When the material is finished, the ton bag is in a cylindrical shape, and then the hook structure pulls the tightening belt at the opening of the ton bag to complete the sealing of the ton bag.

[0037] During the pulling process of the hook structure, the gas pressure in the gas expansion outer container 10 is delivered by the gas delivery pipe 14, and as the gas pressure in the gas expansion outer container 10 fills the inner wall surface, an outward extrusion force is generated, thereby respectively applying an inward pushing force to the outer surface of the expansion pipe 5 and extruding the outer surface of the ton bag to the inner surface of the expansion pipe 5, so as to form clamping and fix the ton bag in the expansion pipe 5 to facilitate the sealing process, and at the same time, the excess pressure is applied to the inner surface of the expansion sleeve 9, so that the expansion sleeve 9 deforms outwardly to release the pressure, and the expansion sleeve 9 is wrapped by the limiting ring 12 as a whole, thereby limiting the excessive deformation of the expansion sleeve 9.

[0038] As the expansion sleeve 9 deforms outwardly, the connecting port of the welded flange 11 deforms, and at the same time, the expansion sleeve 9 also applies an outward pulling force to the T-shaped clamping block 15, and as the middle part of the T-shaped clamping block 15 is extruded outwardly to form a mutual force, the T-shaped protrusions at both ends of the T-shaped clamping block 15 stretch into the annular clamping groove, thereby filling the connecting port of the welded flange 11 to form a sealed state, preventing the gas pressure from leaking due to the deformation of the expansion sleeve 9, so that the gas expansion inner container 13 is in a continuous expansion state, thereby ensuring the fixing effect of the ton bag.
