Description

Technical Field

[0001] This utility model relates to the field of battery production technology, and in particular to a feeding device for fibrous powder. Background Technology

[0002] Dry electrode manufacturing utilizes solid powder to directly mix active materials, conductive agents, and binders, then coats the mixture onto a current collector via pressing or other mechanical methods. The process steps for dry electrodes include dry material mixing, binder fibrillation and mixing, granulation, support film calendering, and current collector lamination. In the binder fibrillation and mixing step, the binder is mixed with the active material, conductive agent, and fixed electrolyte to form a fibrous powder.

[0003] In related technologies, fibrous powders exhibit a flocculent, agglomerated characteristic. This flocculent agglomeration can lead to powder bridging during the feeding process, making it difficult to ensure the uniformity and consistency of the powder's flow. Consequently, this can easily result in discontinuities in the subsequent dry electrode film formation, affecting the product quality of dry-process motors.

[0004] Therefore, there is an urgent need to invent feeding equipment and methods for fibrous powder to solve the above problems. Utility Model Content

[0017] As an optional solution, the driving structure further includes:

[0021] As an optional solution, the cutting mechanism includes:

[0022] The cutting and rolling assembly is disposed at the output end of the pressing mechanism; and

[0023] The third driving component has its output end connected to the cutting assembly. The cutting assembly is directly opposite the fibrous material block in a preset direction.

[0024] As an optional solution, the cutting assembly includes:

[0025] Support frame, with a hollow area; and

[0026] A rigid mesh is fixed on the support frame and seals the hollow area. The rigid mesh and the fibrous material block are directly opposite each other along the preset direction. The rigid mesh has a plurality of cutting holes.

[0027] As an optional solution, the feeding equipment for the fibrous powder also includes:

[0028] A screening mechanism, comprising a screening chamber and a screen, wherein the screening chamber has a screening cavity, and the screening cavity has a second inlet and a screening outlet, the second inlet being directly opposite the output end of the cutting mechanism;

[0034] The feeding device for fibrous powder provided by this utility model compresses the fibrous powder into fibrous blocks using a pressing mechanism, and then cuts the fibrous blocks into fibrous sheets of a preset thickness and size using a cutting mechanism. This allows the cut fibrous sheets to agglomerate together under their own surface tension and form fibrous particles, thus achieving the effect of preparing fibrous powder into fibrous particles. This solves the problem of powder bridging that occurs when directly conveying fibrous powder, and ensures the uniformity and consistency of the conveying of fibrous particles. Furthermore, before preparing the fibrous powder into fibrous particles, it is first compressed into fibrous blocks. This ensures that the density of the fibrous filaments in the fibrous powder is greater than that in the fibrous blocks, and that the degree of stretching of the fibrous filaments in the fibrous powder is also greater than that in the fibrous blocks. The fibrous blocks are then cut into fibrous sheets, and the surface tension of the fibrous sheets agglomerates them into fibrous particles. This ensures that the density of the fibrous filaments in the fibrous powder is less than or equal to the density of the fibrous filaments in the fibrous sheets and the fibrous particles, and that the degree of stretching of the fibrous filaments in the fibrous powder is less than or equal to that in the fibrous sheets and the fibrous particles. By compressing and cutting the fibrous powder, the fibrous filaments within it are repeatedly kneaded, increasing the degree of stretching and density of the filaments per unit area, thereby improving the fibrous effect and ensuring the processing quality of the subsequent electrode films.

[0042] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0043] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] The process steps for dry electrode fabrication include dry material mixing, binder fibrillation and mixing, granulation, support film calendering, and current collector lamination. In the binder fibrillation and mixing step, the binder needs to be mixed with active materials, conductive agents, and fixed electrolytes to form a fibrous powder. In related technologies, the fibrous powder exhibits a flocculent, agglomerated characteristic. This flocculent agglomeration characteristic can lead to powder bridging problems during the feeding process, making it difficult to ensure the uniformity and flow consistency of the fibrous powder. This, in turn, can easily result in discontinuities in the subsequent dry electrode film formation, affecting the product quality of the dry-process motor.

[0047] To solve the above problems, such as Figure 1 As shown, this embodiment provides a feeding device for fibrous powder. The feeding device includes a pressing mechanism 1 and a cutting mechanism 2. The pressing mechanism 1 can press the fibrous powder 1000 into fibrous blocks. The cutting mechanism 2 is located at the output end of the pressing mechanism 1 and can cut the fibrous blocks into fibrous sheets of a preset thickness and size. The fibrous sheets can agglomerate together under their own surface tension to form fibrous particles. The density of the fibers in the fibrous powder 100 is less than or equal to the density of the fibers in the fibrous sheets and the density of the fibers in the fibrous particles. The degree of stretching of the fibers in the fibrous powder 1000 is less than or equal to the degree of stretching of the fibers in the fibrous sheets and the degree of stretching of the fibers in the fibrous particles.

[0048] The feeding equipment for the fibrous powder compresses the fibrous powder 1000 into fibrous blocks using a pressing mechanism 1, and then uses a cutting mechanism 2 to cut the fibrous blocks into fibrous sheets of a preset thickness and size. This allows the cut fibrous sheets to agglomerate together under their own surface tension and form fibrous particles, thus achieving the effect of preparing the fibrous powder 1000 into fibrous particles. This solves the problem of powder bridging that occurs when directly conveying the fibrous powder 1000, and ensures the uniformity and consistency of the conveying of fibrous particles. Furthermore, before preparing the fibrous powder 1000 into fibrous granules, it is first compressed into fibrous blocks. This ensures that the density of the fibers within the fibrous powder 1000 is greater than that within the fibrous blocks, and that the tensile strength of the fibers within the fibrous powder 1000 is greater than that within the fibrous blocks. The fibrous blocks are then cut into fibrous sheets, and the surface tension of the sheets agglomerates them into fibrous granules. This further enhances the density of the fibers within the fibrous powder 1000. The degree of stretching of the fibers in the fiberized sheet is less than or equal to the fiber density in the fiberized granules. The degree of stretching of the fibers in the fiberized powder 1000 is less than or equal to the degree of stretching of the fibers in the fiberized sheet and the fiber density in the fiberized granules. By pressing and cutting the fiberized powder 1000, the fibers in the fiberized powder 1000 are repeatedly kneaded, which improves the degree of stretching and density of the fibers per unit area, thereby improving the degree of fiberization and ensuring the processing quality of the subsequent electrode film.

[0049] It should be noted that the fibrous powder 1000 can be graphite fibrous powder, NCM fibrous powder, or LFP fibrous powder. When the fibrous powder 1000 is graphite fibrous powder, the density of the graphite fibrous block prepared by the pressing mechanism 1 is 0.9–1.25 g / cm³. 3When the fibrous powder 1000 is NCM fibrous powder, the density of the NCM fibrous material block prepared by the pressing mechanism 1 is 2.0–3.1 g / cm³. 3 When the fibrous powder 1000 is LFP fibrous powder, the density of the LFP fibrous material block prepared by the pressing mechanism 1 is 1.2~2.2 g / cm³. 3 .

[0050] In this embodiment, the density of the graphite fiberized material block is 1.0 g / cm³. 3 The density of NCM fiberized material blocks is 2.0 g / cm³. 3 The density of LFP fiberized material blocks is 1.2 g / cm³. 3 In other embodiments, the density of the graphite fiberized material block can be 0.9 g / cm³. 3 1.1g / cm 3 1.15g / cm 3 1.2g / cm 3 1.25g / cm 3 Or at 0.9–1.25 g / cm³ 3 Any value within the range. The density of NCM fiberized blocks can be 2.1 g / cm³. 3 2.2g / cm 3 2.3g / cm 3 2.4g / cm 3 2.5g / cm 3 2.6g / cm 3 2.7g / cm 3 2.8g / cm 3 2.9g / cm 3 3.0g / cm 3 3.1g / cm 3 Or 2.0~3.1g / cm 3 Any value within the range. The density of LFP fiberized blocks can be 1.3 g / cm³. 3 1.4g / cm 3 1.5g / cm 3 1.6g / cm 3 1.7g / cm 3 1.8g / cm 3 1.9g / cm 3 2.0g / cm 3 2.1g / cm 3 2.2g / cm 3 Or 1.2~2.2g / cm 3 Any value within the range is not specifically limited in this embodiment.

[0051] As an optional solution, the pressing mechanism 1 includes a pressing chamber 16, a sealing piston 15, and a driving structure. The pressing chamber 16 has a pressing cavity 161 with an opening, a first feed port 162, and a first discharge port 163. The sealing piston 15 is movably disposed in the pressing cavity 161 along the opening. The sealing piston 15 and the cavity wall of the pressing cavity 161 form a pressing space. The pressing space is connected to the first feed port 162 and the first discharge port 163. The cutting mechanism 2 is disposed at the first discharge port 163. The output end of the driving structure is connected to the sealing piston 15, and the driving structure can drive the sealing piston 15 to move in a preset direction. By setting a pressing chamber 161 in the pressing chamber 16, and setting a first feed port 162, a first discharge port 163 and an opening on the pressing chamber 161, a sealing piston 15 is movably set in the pressing chamber 161 along the opening, so that the sealing piston 15 and the cavity wall of the pressing chamber 161 form a pressing space. The sealing piston 15 is driven by the driving structure to move along a preset direction, which can change the size of the pressing space, thereby pressing the fibrous powder 1000 that enters the pressing space along the first feed port 162 into fibrous blocks, and the pressed fibrous blocks are discharged along the first discharge port 163.

[0052] It should be noted that both the first inlet 162 and the first outlet 163 are equipped with sealing valves. These valves control the opening and closing of the first inlet 162 and the first outlet 163, respectively, so that the fibrous powder 1000 is compressed into fibrous blocks within a sealed compression space. It should also be noted that in this embodiment, the sealing valves are all solenoid valves. Solenoid valves have a simple structure, are highly responsive, and provide good sealing. In other embodiments, the sealing valves may also be ball valves, butterfly valves, or other valve bodies; this embodiment does not impose specific limitations.

[0053] When it is necessary to prepare fibrous powder 1000 into fibrous blocks, firstly, the sealing valve at the first feed port 162 is opened, allowing the fibrous powder 1000 to enter the pressing chamber 161 along the first feed port 162. Then, the sealing valve is resealed at the first feed port 162, and the driving structure drives the sealing piston 15 to move towards the fibrous powder 1000, so as to press the fibrous powder 1000 in the pressing chamber 161 into fibrous blocks. When it is necessary to discharge the pressed fibrous blocks from the pressing chamber 161, the sealing valve at the first discharge port 163 is opened, and the driving structure drives the sealing piston 15 to move towards the first discharge port 163, thereby discharging the fibrous blocks in the pressing chamber 161 along the first discharge port 163.

[0054] To facilitate the determination of the compression status of the fibrous powder 1000 within the compression space, the compression chamber 16 is made of a transparent material, and the compression chamber 16 has graduations extending in a predetermined direction. In other embodiments, the compression chamber 16 may also be made of a transparent material; this embodiment does not impose a specific limitation.

[0055] Specifically, the driving structure includes a first driving component 11 and a second driving component 12. The output end of the first driving component 11 is connected to the sealing piston 15, and the first driving component 11 can drive the sealing piston 15 to rotate around a preset direction. The output end of the second driving component 12 is connected to the first driving component 11, and the second driving component 12 can drive the first driving component 11 to move along the preset direction. By connecting the sealing piston 15 to the output end of the first driving component 11 and connecting the output ends of the first driving component 11 and the second driving component 12, the first driving component 11 drives the sealing piston 15 to rotate around the preset direction, and the second driving component 12 drives the first driving component 11 to move along the preset direction. This ensures the uniformity of extrusion of the fibrous powder 1000 along the preset direction and improves the stretching effect of the fibers in the subsequently rolled and formed fibrous sheets and fibrous particles. It should be noted that in this embodiment, the first driving component 11 is a rotary motor, and the second driving component 12 is a linear motor. Rotary motors and linear motors have simple structures, are highly responsive, and have stable output power. In other embodiments, the first drive member 11 may also be a combination of a rotary cylinder, a linear cylinder and a lead screw and nut, or other rotary drive structures, and the second drive member 12 may be a combination of a linear cylinder, a rotary motor and a lead screw and nut, or other linear drive structures.

[0056] In addition, in this embodiment, the first driving member 11 also includes a transmission structure composed of gears, chains and bearings to change the driving direction and driving accuracy of the first driving member 11.

[0057] To improve the driving accuracy of the sealing piston 15 along a preset direction, the driving structure further includes a connecting structure 13 and a guide rail 14. The connecting structure 13 is disposed between the first driving member 11 and the second driving member 12, and the guide rail 14 extends along the preset direction. The connecting structure 13 and the guide rail 14 are slidably connected. When the second driving member 12 drives the first driving member 11 and the sealing piston 15 to move along the preset direction, the connecting structure 13 slides along the guide rail 14 to provide guidance for the movement of the sealing piston 15 within the pressing cavity 161.

[0058] In addition, in this embodiment, the pressing mechanism 1 also includes a protective cover 17, which covers the outside of the first driving member 11, part of the second driving member 12, the guide slide rail 14 and the connecting structure 13. The sealing piston 15 can extend out of the protective cover 17 and enter the pressing cavity 161 to improve the protection of the sealing piston 15, the first driving member 11, part of the second driving member 12, the guide slide rail 14 and the connecting structure 13.

[0059] In an optional embodiment, the cutting mechanism 2 includes a cutting component 21 and a third driving member 22. The cutting component 21 is disposed at the first discharge port 163, and the third driving member 22 is connected to the output end of the cutting component 21. The cutting component 21 and the fibrous material block are directly opposite each other in a preset direction. The cutting component 21 has a cutting hole 2121 that is open in the preset direction. The third driving member 22 can drive the cutting component 21 to rotate around the preset direction. When the compressed fibrous material block needs to be cut, the third driving component 22 drives the cutting assembly 21 to rotate around a preset direction. Simultaneously, the first driving component 11 drives the sealing piston 15 to rotate around the preset direction, and the second driving component 12 drives the sealing piston 15 to move along the preset direction towards the cutting assembly 21. This causes the cutting holes 2121 within the cutting assembly 21 to cut the fibrous material block into fibrous sheets of a preset thickness and size. Furthermore, during the cutting process, the compressed fibrous material block can be stretched, and the fibers within the fibrous material block can be thoroughly kneaded. This results in the fiber density in the fibrous sheet at the cutting point being greater than or equal to the fiber density in the fibrous powder 1000, and the degree of stretching of the fibers in the fibrous sheet being greater than or equal to the degree of stretching of the fibers in the fibrous powder 1000. It should be noted that in this embodiment, the third driving component 22 is a rotary motor. Rotary motors have a simple structure, are highly responsive, and have stable output power.

[0060] Specifically, such as Figure 2 As shown, the cutting assembly 21 includes a support frame 211 and a rigid mesh 212. The support frame 211 has a hollow area, and the rigid mesh 212 is fixed to the support frame 211 and seals the hollow area. The rigid mesh 212 and the fibrous material block are directly opposite each other along a preset direction. The rigid mesh 212 has multiple cutting holes 2121. By setting the cutting assembly 21 as a support frame 211 and a rigid mesh 212 fixed to the hollow area of ​​the support frame 211, and by covering the rigid mesh 212 with cutting holes 2121, and by having the rigid mesh 212 and the fibrous material block directly opposite each other along a preset direction, when the fibrous material block is being cut, the rigid mesh 212 rotates around the preset direction, so that the cutting holes 2121 on the rigid mesh 212 cut the fibrous material block moving along the preset direction.

[0061] It should be noted that the rigid mesh 212 is made of carbon fiber filaments or stainless wear-resistant steel wire to ensure both structural strength and a long service life. The diameter of the carbon fiber filaments or stainless wear-resistant steel wire is between 0.05mm and 0.5mm. The mesh size of the cut holes 2121 is between 1*1mm and 5*5mm. In this embodiment, the rigid mesh 212 is made of carbon fiber filaments with a diameter of 0.1mm, and the mesh size of the cut holes 2121 inside the rigid mesh 212 is 1*1mm. In other embodiments, the diameter of the carbon fiber filament or stainless wear-resistant steel wire can be any value within the range of 0.05mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm or 0.05mm to 0.5mm, and the mesh size of the cutting hole 2121 can be any value within the range of 1*1mm, 3*3mm, 4*4mm, 5*5mm, 3*4mm, 2*4mm, 3*5mm, 4*5mm or 1*1mm to 5*5mm. This embodiment does not impose specific limitations.

[0062] In this embodiment, as Figure 1 As shown, the feeding equipment for fibrous powder also includes a screening mechanism 3, wherein the screening mechanism 3 includes a screening chamber 31 and a screen 32. The screening chamber 31 has a screening cavity 311, which has a second inlet and a screening outlet. The second inlet is directly opposite to the end of the cutting assembly 21 away from the pressing chamber 16 along a preset direction. The screen 32 is sealed in the screening cavity 311 and is located between the second inlet and the screening outlet. The screen 32 is configured to screen fibrous particles according to their diameter. By setting up a screening mechanism 3 consisting of a screening chamber 31 and a screen 32, a second feed inlet and a screening outlet are opened in the screening chamber 31. The second feed inlet is aligned with the end of the cutting assembly 21 away from the pressing chamber 16 in a preset direction, so that the fibrous sheet from the cutting process enters the screening chamber 311 through the second feed inlet. The screen 32 is then sealed between the second feed inlet and the screening outlet, so that the screen 32 can screen fibrous particles of different diameters. Fiber particles with a diameter smaller than the preset diameter can be discharged from the screening chamber 311 through the screening outlet, so as to ensure the consistency of the size specifications of the discharged fibrous particles and further ensure the consistency of the subsequent electrode film processing.

[0063] In addition, the screening mechanism 3 also includes a feed valve 33, which is located at the second feed inlet. The feed valve 33 is used to control the opening and closing of the second feed inlet to control the entry of fibrous particles into the screening chamber 311. It should be noted that in this embodiment, the feed valve 33 is a solenoid valve. Solenoid valves have a simple structure, are highly responsive, and have good sealing performance. In other embodiments, the feed valve 33 can also be a ball valve, butterfly valve, or other valve body; this embodiment does not impose specific limitations.

[0064] To further improve the processing consistency of the electrode film, the screening mechanism 3 has multiple screens 32, which are spaced apart in the screening chamber 311 along a preset direction. Multiple screening outlets are provided on the screening chamber 311 along the preset direction, and a screen 32 is provided between each pair of adjacent screening outlets. The mesh count of the multiple screens 32 gradually increases from the end closer to the second feed inlet to the direction away from the second feed inlet.

[0065] It should be noted that, in this embodiment, as Figure 1 As shown, the screening mechanism 3 has two screens 32 and three screening outlets. The three screening outlets are arranged in the following order from the second inlet to the outlet away from the second inlet along a preset direction: second outlet 312, third outlet 313, and fourth outlet 314. The two screens 32 are arranged in the same preset direction. The mesh counts of the two screens 32 are 8 and 12, respectively, from the second inlet to the outlet away from the second inlet. The screen 32 with a mesh count of 8, located near the second inlet, is designated as the first screen, and the screen 32 with a mesh count of 12, located away from the second inlet, is designated as the second screen. The screening chamber 311 has the second outlet 312 located between the first screen and the second inlet, the third outlet 313 located between the first screen and the second screen, and the fourth outlet 314 located at the end of the second screen away from the first screen along the preset direction. The second discharge port 312 is used to discharge fibrous particles with a diameter greater than 8 mesh; the third discharge port 313 is used to discharge fibrous particles with a diameter between 8 mesh and 12 mesh; and the fourth discharge port 314 is used to discharge fibrous particles with a diameter less than 12 mesh.

[0066] Understandably, in other embodiments, the specific number of screens 32 and the specific number of screening outlets can also be set according to actual needs. It is only necessary to ensure that the mesh number of the screens 32 gradually increases from the end near the second feed inlet to the direction away from the second feed inlet. This embodiment does not specifically limit the specific mesh number of the screens 32.

[0067] To further improve the screening efficiency of fibrous particles, the screening mechanism 3 also includes a vibration component 34. The output end of the vibration component 34 is connected to the screening chamber 31, and the vibration component 34 is configured to drive the screening chamber 31 to vibrate. By setting the vibration component 34 to drive the screening chamber 31 to vibrate, the fibrous particles in the screening chamber 31 can be moved relative to the screen 32, thereby improving the screening efficiency of the fibrous particles. It should be noted that in this embodiment, the vibration component 34 is a linear cylinder, which drives the screening chamber 31 to reciprocate to drive the screening chamber 31 to vibrate. In other embodiments, the vibration component 34 may also be a linear motor or other reciprocating drive structure; this embodiment does not specifically limit this.

[0068] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
