[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] In this embodiment of the utility model, please refer to Figures 1 to 4 A feeding device for packaging ultrafine powder includes a fixed plate 1 and a hopper 2, wherein the fixed plate 1 is connected to the hopper 2, the hopper 2 contains ultrafine powder, the top of the hopper 2 has a feed inlet, the bottom of the hopper 2 has a discharge outlet, and the discharge outlet is equipped with a control valve. The device also includes:

[0045] A stirring mechanism, connected to hopper 2, is used to stir the fine powder inside the hopper;

[0046] Motor 2, number 6, is connected to the fixed plate 1;

[0047] A threaded rotating rod 15 is connected to the output end of motor 6, and a threaded groove is provided on the upper part of the threaded rotating rod 15.

[0048] Rotating disk 7 is rotatably connected to threaded rotating rod 15;

[0049] A fixed frame 8 is connected to a rotating disk 7. The fixed frame 8 is provided in several groups and is arranged in a circle with equal spacing to support the packaging bag.

[0050] The fixing mechanism is connected at one end to the discharge port at the bottom of the hopper 2 and at the other end to the threaded rotating rod 15. It is used to fix the packaging bag and at the same time to close the discharge port.

[0051] The bag changing mechanism is connected to the rotating disk 7 at one end and to the fixing mechanism at the other end, and is used to replace the packaging bags.

[0052] As one embodiment of this utility model, please refer to Figure 1 The stirring mechanism includes:

[0053] Motor 3 is connected to the top of hopper 2;

[0054] Drive rod 4 is connected to the output terminal of motor 3;

[0055] The stirring rod 5 is connected to the drive rod 4, and the stirring rod 5 is provided in several groups.

[0056] When motor 3 starts, its output drives the drive rod 4 to rotate, which in turn causes the stirring rod 5 to rotate in the hopper 2. Several sets of stirring rods 5 thoroughly stir the ultrafine powder to prevent it from clumping in the hopper 2 and ensure smooth and uniform feeding.

[0057] As one embodiment of this utility model, please refer to Figure 1 , Figure 2 and Figure 4 The fixing mechanism includes:

[0058] Sliding ring 10 is slidably connected to the discharge port of hopper 2;

[0059] The fixed ring 11 is slidably connected to the sliding ring 10;

[0060] Spring 12 has one end connected to sliding ring 10 and the other end connected to fixed ring 11;

[0061] The sleeve rod 13 is threadedly connected to the threaded groove on the threaded rotating rod 15 and is also connected to the sliding ring 10;

[0062] Spring 2 14 is connected at one end to sleeve rod 13 and at the other end to hopper 2.

[0063] In the initial state, spring 12 and spring 24 are in their natural state, and sleeve 13 is threadedly connected to the threaded groove of threaded rotating rod 15;

[0064] When the packaging bag is placed on the fixing frame 8 to fix the packaging bag, the second motor 6 drives the threaded rotating rod 15 to rotate, which in turn drives the sleeve rod 13 to move downward. The sleeve rod 13 drives the sliding ring 10 to move downward synchronously. The sliding ring 10 drives the fixing ring 11 to move downward, so that the fixing ring 11 abuts against the opening of the packaging bag. Together with the fixing frame 8, the packaging bag is fixed. The first spring 12 is compressed, generating a certain clamping force, so that the packaging bag is firmly fixed below the discharge port. At this time, the second spring 14 is in a stretched state.

[0065] When the packaging bag is released, motor 2 6 starts and drives the threaded rod 15 to rotate in the opposite direction. The sleeve 13 moves upward along the threaded groove, driving the sliding ring 10 to move upward, and then driving the fixed ring 11 to move upward until it separates from the opening of the packaging bag. When the sleeve 13 moves upward to a position where there is no threaded groove on the threaded rod 15, the sleeve 13 can no longer move upward. At this time, spring 2 14 is in a compressed state, which is used to provide pressure when motor 2 drives the threaded rod 15 to rotate in the forward direction, so that the sleeve 13 is reconnected to the threaded groove.

[0066] As one embodiment of this utility model, please refer to Figures 1 to 3 The bag changing mechanism includes:

[0067] Ratchet 16 is connected to rotating disk 7;

[0068] The sliding sleeve 17 is slidably connected to the threaded rotating rod 15;

[0069] The fixed rod 18 is connected to the sliding sleeve 17;

[0070] The locking block 19 is rotatably connected to the fixing rod 18;

[0071] The spiral spring 20 is connected at one end to the locking block 19 and at the other end to the fixing rod 18;

[0072] Rotating ring 24 is rotatably connected to sleeve rod 13;

[0073] One end of the folding rod 21 is connected to the rotating ring 24;

[0074] The connecting cylinder 22 is slidably connected to the folding rod 21 and is also connected to the sliding sleeve 17;

[0075] Spring 23 has one end connected to the other end of the bending rod 21 and the other end connected to the connecting cylinder 22.

[0076] During the process of fixing the packaging bag, the locking block 19 does not engage with the ratchet 16. At this time, the ratchet 16 cannot rotate, so the rotating disk 7 cannot rotate. After the fixing is completed, the locking block 19 is located at the bottom of the ratchet 16, and there is a certain distance between the two in the longitudinal direction.

[0077] When the packaging bag needs to be replaced, motor 6 drives the threaded rod 15 to rotate in the opposite direction. At this time, the sleeve rod 13 drives the locking block 19 to move upward. When the fixing ring 11 moves upward until the packaging bag opening is disengaged, the locking block 19 remains at the bottom of the ratchet 16. As the fixing ring 11 continues to move upward, the locking block 19 moves to engage with the ratchet 16. At this time, the locking block 19 drives the ratchet 16 to rotate, and the ratchet 16 drives the rotating disk 7 to rotate, so that another set of packaging bags rotates to the bottom of the discharge port. The packaging bag filled with powder rotates away from the discharge port, and motor 6 stops rotating.

[0078] In this embodiment, the rotation speed of the second motor 6 is relatively slow.

[0079] As one embodiment of this utility model, please refer to Figure 1 It also includes:

[0080] Rotating wheel 9 is connected to rotating disk 7 and abuts against fixed plate 1.

[0081] The rotating wheel 9 supports the rotating disk 7.

[0082] The working principle of this utility model is as follows: In the initial state, spring 12 and spring 24 are in their natural state, and sleeve rod 13 is threadedly connected to the threaded groove of threaded rotating rod 15.

[0083] When the packaging bag is placed on the fixing frame 8 to fix it, the motor 6 drives the threaded rotating rod 15 to rotate, which in turn drives the sleeve rod 13 to move downward. The sleeve rod 13 drives the sliding ring 10 to move downward synchronously. The sliding ring 10 drives the fixing ring 11 to move downward, so that the fixing ring 11 abuts against the opening of the packaging bag. Together with the fixing frame 8, the packaging bag is fixed. The spring 12 is compressed, generating a certain clamping force, so that the packaging bag is firmly fixed below the discharge port. At this time, the spring 14 is in a stretched state. During the process of fixing the packaging bag, the locking block 19 does not engage with the ratchet 16. At this time, the ratchet 16 cannot rotate, so the rotating disk 7 cannot rotate. After the fixing is completed, the locking block 19 is located at the bottom of the ratchet 16, and there is a certain distance between the two in the longitudinal direction.

[0084] When the control valve is opened, the powder falls from the outlet into the packaging bag for collection. Motor 3 starts, and its output end drives the drive rod 4 to rotate, which in turn causes the stirring rod 5 to rotate in the hopper 2. Several sets of stirring rods 5 fully stir the ultrafine powder to prevent the ultrafine powder from clumping in the hopper 2 and ensure smooth and uniform feeding.

[0085] After a certain weight of material is discharged, the control valve closes, and motor 6 starts, driving the threaded rod 15 to rotate in the opposite direction. The sleeve rod 13 moves upward along the threaded groove, driving the sliding ring 10 to move upward, which in turn drives the fixed ring 11 to move upward until it separates from the packaging bag opening. When the sleeve rod 13 moves upward to a point where there is no threaded groove on the threaded rod 15, the sleeve rod 13 can no longer move upward. At this time, spring 14 is in a compressed state. The sleeve rod 13 drives the locking block 19 to move upward. When the fixed ring 11 moves upward until it separates from the packaging bag opening, the locking block 19 is still located at the bottom of the ratchet 16. As the fixed ring 11 continues to move upward, the locking block 19 moves to engage with the ratchet 16. At this time, the locking block 19 drives the ratchet 16 to rotate, and the ratchet 16 drives the rotating disk 7 to rotate, causing another set of packaging bags to rotate to the bottom of the discharge port. The packaging bags filled with powder rotate away from the discharge port, and motor 6 stops rotating.
