A feeding chute, communicating with the feeding end of the furnace body, is formed through the side of the door frame away from the furnace body, and the feeding chute is connected to the sliding groove. The drive member drives the door body to cover or open the feeding chute. This application improves the operational safety of feeding or discharging materials from the sintering furnace.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:

[0005] The pre-pressing, static pressing, and demolding of neodymium iron boron magnets all require a lot of manual operation. When demolding the blank, workers need to place the mold on the workbench and tap it to remove the blank from the mold. When there are many molds that need to be demolded, the efficiency of workers can easily decrease. Utility Model Content

[0006] To address the problem of decreased worker efficiency when a large number of molds need to be demolded, the purpose of this invention is to provide an apparatus for preparing high resistivity sintered NdFeB magnets.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: a stirring and grinding integrated device for conductive slurry of lithium battery, including a box body, a first slot is provided on the top of the box body, a conveyor belt is provided inside the first slot, and a demolding component is provided on the outside of the box body;

[0008] The demolding assembly includes a demolding box, which is fixedly connected to a housing. The top of the demolding box has a slot, inside which a turntable is movably secured. A fixed box is fixedly installed at the top of the turntable, and evenly distributed strip plates are fixedly installed at the bottom of the fixed box. A first and second drop groove are evenly distributed on the top of the turntable and the lower inner wall of the slot, respectively. A pad is fixedly installed inside the first drop groove.

Detailed Implementation

[0025] 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.

[0026] like Figure 1-5As shown, this utility model discloses an integrated stirring and grinding device for lithium battery conductive slurry, and provides the following two embodiments:

[0027] Example 1: Includes a box body 1, with a first slot 11 on the top of the box body 1, a conveyor belt 12 inside the first slot 11, and a demolding assembly 2 on the outside of the box body 1.

[0028] The demolding assembly 2 includes a demolding box 21, which is fixedly connected to the box body 1. A slot 22 is provided on the top of the demolding box 21, and a turntable 23 is movably mounted inside the slot 22. A fixed box 24 is fixedly installed on the top of the turntable 23, and evenly distributed strip plates 25 are fixedly installed on the bottom of the fixed box 24. A first drop groove 26 and a second drop groove 27 are evenly distributed on the top of the turntable 23 and the lower surface of the inner wall of the slot 22, respectively. A pad 28 is fixedly installed inside the first drop groove 26. An electric push rod 29 is fixedly installed above the fixed box 24. The output end of the electric push rod 29 passes through the top of the fixed box 24, and a connecting ring 291 is fixedly connected to the output end of the electric push rod 29. A ring-shaped support plate 292 is fixedly installed on the outer side of the ring 291. A tapping pad 293 is fixedly installed on the side of the support plate 292 away from the connecting ring 291. The top of the fixed box 24 has evenly distributed second slots 294. Multiple support plates 292 pass through the corresponding second slots 294. Fixed rods 295 are fixedly installed inside the multiple second slots 294. Multiple fixed rods 295 move through the corresponding support plates 292. The top of the demolding box 21 has multiple conveying grooves 296. Multiple conveying grooves 296 are connected to the corresponding second dropping grooves 27. A rotating rod 297 rotates through the inside of the demolding box 21. One end of the rotating rod 297 is fixedly connected to the turntable 23.

[0029] Example 2 differs from Example 1 in that: symmetrically distributed connecting rods 3 are fixedly installed at the top of the housing 1, and first limiting plates 31 are fixedly installed on the outer sides of both connecting rods 3. Symmetrically distributed second limiting plates 32 are fixedly installed above the housing 1. The second limiting plates 32 are in contact with the first limiting plates 31. The mold is limited by the first limiting plates 31 and the second limiting plates 32, so that the mold is accurately inserted into the first drop groove 26, thereby preventing the mold from shifting during the tapping process and improving the demolding efficiency.

[0030] The top of the housing 1 is fixedly installed with symmetrically distributed stabilizing plates 4. Multiple stabilizing rods 41 are fixedly inserted through the outer side of each of the two stabilizing plates 4. The other end of the stabilizing rods 41 is fixedly connected to the second limiting plate 32. The stabilizing plates 4 and stabilizing rods 41 can support the second limiting plate 32, so that it can smoothly limit the mold.

[0031] A support frame 5 is fixedly installed on the top of the fixed box 24. The electric push rod 29 is fixedly installed on the top of the support frame 5. The output end of the electric push rod 29 passes through the support frame 5. The electric push rod 29 can be supported by the set stabilizer 5, thereby improving its operational stability.

[0032] A motor 6 is coaxially fixedly installed at the other end of the rotating rod 297 away from the turntable 23. The motor 6 is fixedly installed inside the demolding box 21. The motor 6 enables the rotating rod 297 to rotate smoothly, thereby demolding the blank.

[0033] The side of the box 1 closest to the demolding box 21 is inclined, which allows the mold to move on the inclined box 1 and thus smoothly insert it into the first drop groove 26.

[0034] There are four conveying channels 296, located on both sides of the demolding box 21, with three on one side and one on the other. By setting multiple conveying channels 296, the blanks can be conveyed and collected conveniently.

[0035] Working principle: In actual use, the mold containing the blank is placed above the conveyor belt 12. Under the limit of the first limiting plate 31 and the second limiting plate 32, the mold moves to the middle of two strip plates 25 and is stuck in the first drop groove 26. The mold is supported by the pad plate 28 to prevent it from falling. Then, the drive rotating rod 297 is rotated to drive the turntable 23 to rotate, so that the two strip plates 25 that are not loaded into the mold and the second limiting plate 32 are aligned, until all strip plates 25 are loaded into the mold.

[0036] By activating the electric push rod 29, its output end retracts. At this time, the support plate 292 rotates towards the electric push rod 29 under the limit of the fixed rod 295. Simultaneously, the striking pad 293 moves towards the mold and makes contact. This process is repeated, causing the striking pad 293 to strike the mold, thereby allowing the blank in the mold to enter the conveying groove 296 through the second drop groove 27, completing the demolding process of the blank.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
