[0033] Reference Figures 1-8 ,

[0034] A powder bagging device includes a powder bag 1 with an opening 11. The device comprises an air pump, a fixed frame 2, a movable frame 3, a discharge pipe 4, a first inflation sealing ring 5, a telescopic pipe 6, and a second inflation sealing ring 7. The first inflation sealing ring 5 has a first air inlet pipe connected to the air pump output. The air pump injects air into the first inflation sealing ring 5 through the first air inlet pipe. The second inflation sealing ring 7 is similarly described and will not be elaborated here. The movable frame 3 is movably mounted on the fixed frame 2. The movement of the movable frame 3 relative to the fixed frame 2 is prior art and will not be elaborated here. The fixed frame 2 has a bearing surface 211 for placing the powder bag 1. One end of the discharge pipe 4 extends through the fixed frame 2 and the movable frame 3 towards the bearing surface 211. The powder bagging device also includes a corrugated pipe 8. The connecting pipe includes a first pipe body and a second pipe body. The first pipe body passes through the fixed frame 2 and is fixed to the fixed frame 2. The end of the first pipe body facing the bearing surface 211 is connected to the corrugated pipe 8. The second pipe body passes through the movable frame 3 and is fixed to the movable frame 3. The end of the second pipe body facing away from the bearing surface 211 is connected to the corrugated pipe 8. When the movable frame 3 moves closer to or away from the bearing surface 211 on the fixed frame 2, the corrugated pipe 8 extends or retracts to allow the discharge pipe 4 to move closer to or away from the bearing surface 211. The bag opening 11 is connected to the discharge pipe 4. The end of the discharge pipe 4 facing away from the bearing surface 211 is connected to the hopper. The discharge pipe 4 is used to inject the powder in the hopper into the powder bag 1. The first inflatable sealing ring 5 is disposed on the end of the discharge pipe 4 near the bearing surface 211; the first inflatable sealing ring 5 abuts against the inner wall of the bag opening 11; one end of the telescopic tube 6 is connected to the movable frame 3, and the other end of the telescopic tube 6 extends towards the bearing surface 211; the diameter of the telescopic tube 6 is larger than the diameter of the discharge pipe 4; the second inflatable sealing ring 7 is disposed on the inner wall of the telescopic tube 6; the second inflatable sealing ring 7 abuts against the outer wall of the bag opening 11. By setting the first inflatable sealing ring 5 abutting against the inner wall of the bag opening 11 and the second inflatable sealing ring 7 abutting against the outer wall of the bag opening 11, a double seal is formed to prevent powder from overflowing from between the bag opening 11 of the powder bag 1 and the discharge pipe 4 during the powder filling process.

[0035] If some powder bags 1 are small, or the length of the bag opening 11 is too short, the user can first place the powder bag 1 on the bearing surface 211 and control the moving frame 3 to move towards the bearing surface 211. When the moving frame 3 moves towards the bearing surface 211, the corrugated pipe 8 set between the fixed frame 2 and the moving frame 3 will extend. After the moving frame 3 moves, the user can put the bag opening 11 of the powder bag 1 onto the discharge pipe 4. After the first inflation sealing ring 5 expands, it can press against the inner wall of the bag opening 11. Then the user pulls the telescopic pipe 6 towards the bearing surface 211, so that the second inflation sealing ring 7 is above the first inflation sealing ring 5, or the bag opening 11 is between the second inflation sealing ring 7 and the first inflation sealing ring 5, or the second inflation sealing ring 7 is below the first inflation sealing ring 5. At the same time, the second inflation sealing ring 7 can press against the outer wall of the bag opening 11 after inflation. At this time, the powder can be injected into the powder bag 1.

[0036] In other embodiments, the powder bagging device includes a telescopic rod and a fixed tube. One end of the telescopic rod is connected to the movable frame 3, and the other end of the telescopic rod is connected to the outer or inner wall of the fixed tube. A second inflatable sealing ring 7 is provided inside the fixed tube.

[0037] Specifically, refer to Figure 1 , Figures 4-6The powder bag 1 is provided with multiple lifting lugs 12; the powder bagging device also includes: a first hook 9, a U-shaped plate 100, and a hydraulic cylinder 101; the U-shaped plate 100 is provided with an installation gap 1001; the side of the U-shaped plate 100 facing away from the installation gap 1001 is connected to the movable frame 3; the first hook 9 is disposed within the installation gap 1001; one end of the first hook 9 located within the installation gap 1001 is rotatably connected to the U-shaped plate 100, and the other end of the first hook 9 located outside the installation gap 1001 forms an entrance 91 between it and the U-shaped plate 100 for the lifting lugs 12 to enter; the hydraulic cylinder 101 is disposed on the U-shaped plate 100, and the output end of the hydraulic cylinder 101 extends into the installation gap 1001 and is rotatably connected to the first hook 9, so that the entrance 91 becomes larger or smaller. In this embodiment, when the output end of the hydraulic cylinder 101 extends, the entrance 91 becomes smaller, and vice versa. After the user places the powder bag 1 on the bearing surface 211, the user can control the hydraulic cylinder 101 to enlarge the inlet 91, then hang the lifting lug 12 on the first hook 9, and then control the hydraulic cylinder 101 to reduce the inlet 91 to prevent the lifting lug 12 from detaching from the first hook 9 during the filling process. After the powder bag 1 is filled with powder, the powder bag 1 expands, and the lifting lug 12 will tighten towards the powder bag 1. At this time, the user will have difficulty removing the lifting lug 12 from the first hook 9. However, the hydraulic cylinder 101 in this embodiment can control the inlet 91 to enlarge. After the inlet 91 enlarges, the lifting lug 12 will slide on the first hook 9. When the end of the first hook 9 outside the installation gap 1001 faces the ground, the lifting lug 12 will detach from the first hook 9.

[0038] Specifically, refer to Figure 6 A limiting rod 1002 is also provided within the installation gap 1001; the first hook 9 is provided with an abutment portion 92; the abutment portion 92 is a block structure. When the abutment portion 92 abuts against the limiting rod 1002, the end of the first hook 9 located outside the installation gap 1001 is at its minimum distance from the U-shaped plate 100. In this embodiment, the hydraulic cylinder 101 is mounted on one side of the U-shaped plate 100 via a fixing plate, and the end of the first hook 9 located outside the installation gap 1001 is located below the hydraulic cylinder 101. To prevent the end of the first hook 9 located outside the installation gap 1001 from interfering with the hydraulic cylinder 101 when it is close to the U-shaped plate 100, a limiting rod 1002 is provided in this embodiment to limit the minimum distance of the inlet 91 of the first hook 9.

[0039] Specifically, refer to Figure 3The powder bagging device also includes: a support plate 21, a vibrating motor 102, and a shock-absorbing airbag 103. A support surface 211 is provided on the support plate 21, and the vibrating motor 102 is mounted on the side of the support plate 21 facing away from the support surface 211. The shock-absorbing airbag 103 is mounted on the support plate 21; the side of the shock-absorbing airbag 103 facing away from the support plate 21 abuts against the fixing frame 2. During the filling process, the vibrating motor 102 is used to vibrate the support plate 21 so that the powder bag 1 placed on the support surface 211 can be filled with powder. The shock-absorbing airbag 103 is provided to prevent the vibrating motor 102 from causing the fixing frame 2 to vibrate during operation.

[0040] Specifically, refer to Figures 4-5 A second hook 104 is also provided within the installation gap 1001. The end of the second hook 104 located outside the installation gap 1001 abuts against the end of the first hook 9 located outside the installation gap 1001. During the filling process, the position of the powder in the powder bag 1 is not fixed. When there is too much powder on one side of the powder bag 1, the powder bag 1 will tilt, and the lifting lug 12 will also move in the direction of the tilt of the powder bag 1. In some cases, the lifting lug 12 may even detach directly from the first hook 9. Therefore, in this embodiment, a second hook 104 is provided to prevent the lifting lug 12 from detaching from the hook.

[0041] Specifically, refer to Figure 6 The first hook 9 has an abutment groove 93 at one end outside the installation gap 1001, and the second hook 104 has its other end outside the installation gap 1001 abutting within the abutment groove 93. Specifically, the second hook 104 has an abutment surface at one end outside the installation gap 1001, and the abutment surface abuts within the abutment groove 93. Under normal circumstances, the ends of the first hook 9 and the second hook 104 that are in contact are usually in point contact. When the powder bag 1 tilts, the lifting lug 12 will pass directly between the first hook 9 and the second hook 104. Point contact cannot prevent the lifting lug 12 from detaching from the first hook 9. Therefore, in this embodiment, an abutment groove 93 is provided on the first hook 9, so that the end of the second hook 104 outside the installation gap 1001 abuts within the abutment groove 93, replacing the traditional point contact with surface contact, effectively preventing the lifting lug 12 from detaching from the hook.

[0042] Specifically, refer to Figures 4-5 The U-shaped plate 100 is also equipped with a slider 105; the movable frame 3 is equipped with a guide rail 106; the slider 105 is disposed on the side of the U-shaped plate 100 facing away from the installation gap 1001, specifically, the slider 105 is fixedly connected to the U-shaped plate 100 by bolts. The slider 105 is slidably connected to the guide rail 106. Some powder bags 1 are of different sizes, and the positions of the lifting lugs 12 disposed on the powder bags 1 are also different. Therefore, in this embodiment, the slider 105 and the guide rail 106 are provided so that the U-shaped plate 100 can move on the guide rail 106 so that the lifting lugs 12 in different positions can be hung on the first hook 9.

[0043] Specifically, refer to Figure 8 The inner wall of the telescopic tube 6 has protrusions 61, which are block-shaped structures. Two protrusions 61 are provided, and a mounting groove is formed between them. The second inflatable sealing ring 7 is placed within the mounting groove. The second inflatable sealing ring 7 is usually difficult to directly fix inside the telescopic tube 6. Therefore, in this embodiment, protrusions 61 are provided so that the second inflatable sealing ring 7 can be placed inside the telescopic tube 6 through the mounting groove. When the second inflatable sealing ring 7 is placed in the mounting groove, the second air inlet pipe on the second inflatable sealing ring 7 passes through the outer wall of the telescopic tube 6 and connects to the air pump. The user can provide threads on the outer wall of the second air inlet pipe and fix the second air inlet pipe to the outer wall of the telescopic tube 6 with a nut. The nut, in conjunction with the two protrusions 61, fixes the second inflatable sealing ring 7 inside the telescopic tube 6.
