[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To address the technical problem of dust overflowing from the feed inlet of a powder mixer caused by tilting feeding, this utility model provides a feeding device that can transport a sagger containing powder into the outer shell via a conveying mechanism, a flipping mechanism, a receiving mechanism, and a discharging mechanism. The device then flips and dumps the powder, creating a barrier between the sagger and the feed inlet to reduce dust overflow. Furthermore, the sagger can be pushed out from the discharging mechanism, enabling automatic feeding and discharging, facilitating operation, improving efficiency, and reducing dust generated during feeding.

[0020] It should be noted that the feeding device described in this utility model is used for, but not limited to, mixing and feeding of battery positive electrode powder. For ease of explanation, this utility model only uses the application of the feeding device to mixing and feeding of battery positive electrode powder as an example. The principle of the feeding device applied to other types of equipment is essentially the same as that applied to mixing and feeding of battery positive electrode powder, and will not be described in detail here.

[0021] Please see Figure 1-6 This utility model provides a feeding device for pouring powder from a sagger 6 into a powder mixer. The device includes a housing 1, a conveying mechanism 2, a tilting mechanism 3, a receiving mechanism 4, and a discharging mechanism 5. One end of the housing 1 has an inlet 101, and the other end has an outlet 102. The inlet 101 is horizontal, and the outlet 102 faces downwards. The outlet 102 is connected to the inlet of the powder mixer, forming a horizontal conveying mechanism for the sagger 6, which is tilted and tilted downwards to feed the powder. The conveying mechanism 2 is located at the inlet 101 and is used to convey the sagger 6 containing powder along the length of the housing 1, transporting the sagger 6 into the interior of the housing 1. The housing 1 forms an external enclosure, creating a certain distance between the tilting area and the inlet 101 to reduce dust spillage. The tilting mechanism 3 is installed inside the housing and has a rotatable drive end for tilting the sagger 6 and, together with the sagger 6, disconnecting the inlet 101 from the tilting side of the sagger 6, thus tilting it to the tilting position. When the dust generation is at its maximum, the feed inlet 101 is blocked to prevent dust overflow. Combined with the distance control between the pouring area and the feed inlet 101, the dust overflow prevention effect is relatively good before and after the entire pouring process. The receiving mechanism 4 is installed inside the outer shell and has a rotatable receiving frame for receiving the overturned sagger 6 and pushing the inverted sagger 6 to move. When the sagger 6 is overturned, dust residue inside the sagger 6 is avoided. The discharge mechanism 5 is installed inside the outer shell and has a valve plate that can be opened and closed elastically. It is set on the outer shell 1 along the pushing direction of the receiving mechanism 4, so that the sagger 6 can push open the valve plate. After the sagger 6 leaves, it elastically pulls back and closes the valve plate. When the sagger 6 is overturned, its bottom surface is facing upward and is in a flat state. At this time, the valve plate can fit against its bottom surface, so that a large gap is avoided at the opening of the valve plate, and the position where the sagger is pushed out also has a dust overflow prevention effect.

[0022] In one embodiment, please refer to Figure 2 and Figure 3 To create a partition between the inlet 101 and the sump during the flipping action, the flipping mechanism 3 includes a first telescopic drive member 31, a plate 32, and a cylindrical seat 33. The cylindrical seat 33 is rotatably connected to the inner bottom wall of the outer shell 1. A right-angle groove 301 is formed at the top of the cylindrical seat 33. The plate 32 is connected to one side of the right-angle groove 301, allowing one side of the sagger 6 to be inserted into the right-angle groove 301 and abut against the top of the plate 32. During the conveying action of the sagger 6, it is conveyed onto the plate 32 and inserted into the right-angle groove 301. At this time, the front and rear sides of the sagger 6 abut against and slide against the front and rear side walls of the outer shell 1, respectively. During rotation, the entire sagger 6 forms a baffle structure. When its right side abuts against the inner top wall of the outer shell 1, a partition is formed. For details, please refer to [reference needed]. Figure 3 and Figure 4 .

[0023] In one embodiment, please refer to Figure 2 and Figure 3 To receive the sagger 6 and avoid obstructing the powder feeding, the receiving mechanism 4 includes a second telescopic drive 41, an upper frame 42, and a support frame 43. The upper frame 42 has two connecting ends, which are respectively hinged to the two support frames 43. The support frames 43 correspond to the front and rear sides of the sagger 6. When inverted, they support the top two sides of the sagger 6. The two support frames 43 are respectively hinged to the front and rear side walls of the outer shell 1, forming an open space between the two support frames 43 for the powder to pass through, thus avoiding obstructing the powder feeding. The telescopic end of the second telescopic drive 41 is hinged to the upper frame 42, and the other end of the second telescopic drive 41 is hinged to the outer shell 1. Through the telescopic action of the second telescopic drive 41, the support frame 43 can be lifted to flip upward or lowered to rotate downward.

[0024] Specifically, the upper frame 42 is U-shaped and can be fitted onto the outside of the plate 32 and the entire sagger 6 so as not to interfere with the flipping of the sagger 6. The support frame 43 is L-shaped and can support the end face and bottom face of the sagger 6 after it has been flipped.

[0025] Understandably, when the right-angle groove 301 rotates to the tilting position, it is parallel to and docks with the L-shaped support frame 43, thus forming a bottom guide. The L-shaped support frame 43 abuts against the bottom of the sagger 6 at this position, allowing the sagger 6 to slide onto the support frame 43. That is, the height of the right-angle groove 301 is less than the height of the sagger 6, which matches the bottom of the L-shaped support frame 43 at this position of the sagger 6.

[0026] Furthermore, position sensors 104 can be installed at both the tilting position and the receiving position to detect whether the crucible 6 has detached from the plate 32 and whether the crucible 6 has moved to the receiving position of the support frame 43. Existing mature position sensing technology can be used, which is an existing mature control method of automation control, and will not be elaborated on here.

[0027] Understandably, the position sensor 104 can be a proximity sensor or a laser sensor; there is no single limitation, as long as it can achieve the purpose of position detection.

[0028] In one embodiment, please refer to Figure 2 and Figure 3 In order to transport the sagger 6 and provide a accommodating space for the plate 32, the conveying mechanism 2 includes two conveyor belts 21, which are respectively installed on the front and rear side walls of the outer casing 1 and placed on both sides of the plate 32.

[0029] Furthermore, the discharge port 102 is located at the bottom of the outer shell 1 and directly below the receiving mechanism 4. The inlet 101 is located on one side of the outer shell 1, and the discharge mechanism 5 is located on the other side of the outer shell 1. The sagger 6 is horizontally conveyed in, and after being flipped, it is fed downwards.

[0030] In one embodiment, please refer to Figure 2 and Figure 3 The discharge mechanism 5 includes a valve plate body 51. The outer shell 1 has a bowl outlet 103 on the side opposite to the open space. The valve plate body 51 is hinged in the bowl outlet 103 and a torsion spring is installed between it and the outer shell 1. The torsion spring provides elastic pull-back. After unfolding, it can be elastically pulled back to the original position.

[0031] In one embodiment, please refer to Figure 2 and Figure 6 In order to push out the sagger 6, the discharge mechanism 5 also includes a third telescopic drive member 52. The third telescopic drive member 52 is installed inside the outer shell 1, and its telescopic end is directly opposite to the valve plate body 51. A push plate 53 is connected to the telescopic end of the third telescopic drive member 52 to push the sagger 6 toward the valve plate body 51. By telescopically extending and retracting the third telescopic drive member 52, the push plate 53 is pushed to move, pushing the sagger 6 out of the outlet 103.

[0032] In one embodiment, please refer to Figure 3The outer shell 1 includes a cylindrical feeding section 11, an arc-shaped section 12, and a discharging section 13. The cylindrical feeding section 11, the arc-shaped section 12, and the discharging section 13 are connected sequentially along the conveying direction of the sagger 6. The height of the cylindrical feeding section 11 is less than the diameter of the arc-shaped section 12, so that after the sagger 6 is flipped, it can be separated and leave an empty space above, preventing a large amount of dust from overflowing into the feed inlet 101. The diameter of the arc-shaped section 12 matches the length of the plate 32, thereby forming a partition. The sagger 6 also matches the length of the plate 32, can rotate without obstruction, and can be close to the inner top wall of the arc-shaped section 12.

[0033] It is understandable that the first telescopic drive component 31, the second telescopic drive component 41, and the third telescopic drive component 52 can all be existing equipment with telescopic functions, such as hydraulic push rods, and are not limited to one specific device.

[0034] This utility model also provides a feeding device, including the feeding device as described in any of the above embodiments, which is installed on the feeding end of the feeding device.

[0035] To better understand this utility model, the following is combined with... Figures 1 to 6 The technical solution of this utility model is described in detail as follows: The sagger 6 is inserted into the feed inlet 101 and placed on top of the two conveyor belts 21 for conveying. It is conveyed to the plate 32 and continues to move until it enters the right-angle groove 301 of the cylindrical seat 33. Then, the first telescopic drive member 31 extends, pushing the plate 32 and the cylindrical seat 33 to rotate, flipping the sagger to the left so that it is tilted to the lower left. At this time, the powder is poured out, and the sagger 6 contacts the support frame 43 and slides to the left. Then, the first telescopic drive member 31 retracts, and the plate 32 and the cylindrical seat 33 return to their original positions. Then, the second telescopic drive member 41 extends and retracts, rotating the support frame 43 from the tilted state to the horizontal state, inverting the sagger 6 and pouring out all the remaining powder. Finally, the third telescopic drive member 52 moves the push plate 53, pushing the sagger 6 towards the outlet 103, pushing the valve plate body 51 to rotate, and pushing it out of the outlet 103.

[0036] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
