[0032] Dry electrode fabrication technology, as a novel electrode manufacturing technology, has become a key focus of research and development in the global battery industry in recent years. Compared with traditional wet electrode technology, dry electrode technology has the following advantages: the entire manufacturing process of dry electrodes is environmentally friendly; dry electrodes eliminate the baking process after coating, thus greatly reducing energy consumption; the manufacturing cost, investment cost, and material cost of dry electrodes are all lower than those of wet processes; the electrode sheets synthesized by dry electrodes have better performance; the dry electrode process is significantly more efficient than the wet process; and the dry electrode process has better compatibility.

[0033] Dry electrode fabrication eliminates the need for liquids. The technology involves dry mixing of active materials, binders, and conductive additives in specific proportions. The binder's fibrous action forms a supportive film, which is then bonded to the current collector via a roll forming process. The main synthesis processes for dry electrodes include material mixing, material fibrosis, formation of a self-supporting film, and film-current collector lamination. Material mixing is the first step in dry electrode fabrication, and the uniformity of this mixing directly affects the electrode quality.

[0034] However, current dry electrode material mixing processes primarily utilize traditional equipment such as high-speed mixers and air jet mills. While these devices can meet production demands to some extent, their production methods have limitations. Specifically, they mainly employ an intermittent production model, requiring frequent shutdowns and restarts, resulting in long mixing cycles, low efficiency, and difficulty in meeting the demands of large-scale, continuous production. This restricts efficiency improvements and increases production costs.

[0035] To address the aforementioned issues, the inventors investigated the limitations of existing material mixing mechanisms, improved upon them, and designed a device capable of continuous material mixing without the need to replace the mixing equipment. This prevented the problem of low mixing efficiency caused by discontinuous material mixing processes and achieved the goal of improving the continuity of the material mixing process.

[0036] Based on this, the present application discloses a material mixing mechanism that solves the problem of decreased mixing efficiency caused by discontinuous material mixing process.

[0037] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0038] Please refer to Figures 1, 2 and 3. Figure 1 is a structural schematic diagram of the material mixing device 200 provided in the embodiment of this application. Figure 2 is a structural schematic diagram of the first screw mixing module 1 provided in the embodiment of this application. Figure 3 is a structural schematic diagram of the second screw mixing module 2 provided in the embodiment of this application. This application embodiment provides a material mixing mechanism 100, including: a first screw mixing module 1, which includes a first housing 11 and a first mixing component 12. The first housing 11 has a first mixing chamber 11a inside, and is provided with a first inlet and a first outlet. The first inlet and the first outlet are arranged at intervals along a first horizontal direction X and are connected to the first mixing chamber 11a. The first mixing component 12 is located in the first mixing chamber 11a and is used to push the material along the first horizontal direction X to the first outlet, and to perform preliminary mixing of the material during the pushing process; and a second screw mixing module 2, which includes a second housing 21 and a second mixing component 22. The second housing 21 has a second mixing chamber 21a inside. The second housing 21 is provided with a second inlet and a second outlet, which are arranged at intervals along the first horizontal direction X. The second inlet and the second outlet are connected to the second mixing chamber 21a, and the second inlet is connected to the first outlet. The second mixing component 22 is located in the second mixing chamber 21a. The second mixing component 22 is used to push the pre-mixed material along the first horizontal direction X to the second outlet, and to perform secondary mixing on the pre-mixed material during the pushing process. The drive component 3 is connected to the first mixing component 12 and the second mixing component 22. The drive component 3 is used to drive the first mixing component 12 and the second mixing component 22 to rotate in opposite directions, so that the first mixing component 12 and the second mixing component 22 push the material along the first horizontal direction X, and to mix the material during the pushing process.

[0039] The first screw mixing module 1 includes a first housing 11, which is used to accommodate the other components included in the first screw mixing module 1. The first housing 11 provides a stable operating space for the other components included in the first screw mixing module 1, and can protect the other internal components from dust, moisture and other substances, thereby ensuring the effective operation of the first screw mixing module 1.

[0040] Optionally, the surface of the first housing 11 may be provided with an openable sealing cover. When it is necessary to replace, clean or repair the components inside the first screw mixing module 1, the operator can open the sealing cover without disassembling the entire first housing 11, thereby shortening the maintenance time and reducing the difficulty of operation.

[0041] The first housing 11 has a first mixing chamber 11a inside to accommodate the material to be mixed. The first housing 11 is provided with a first inlet and a first outlet, which are connected to the first mixing chamber 11a. The material can enter the first mixing chamber 11a through the first inlet.

[0042] The first feed inlet and the first discharge outlet are arranged at intervals along the first horizontal direction X. The first mixing component 12 is located in the first mixing chamber 11a. The first mixing component 12 is used to push the material along the first horizontal direction X to the first discharge outlet and to perform preliminary mixing of the material during the pushing process. After being pushed to the first discharge outlet, the material after preliminary mixing can be discharged from the first mixing chamber 11a under the action of gravity.

[0043] Optionally, the first mixing component 12 may be a spiral mixing structure, or it may be a vibration structure or other structure that can mix materials while pushing them to move. This application does not limit this aspect.

[0044] The second screw mixing module 2 includes a second housing 21, which is used to accommodate the other components included in the second screw mixing module 2. The second housing 21 provides a stable operating space for the other components included in the second screw mixing module 2, and can protect the other internal components from dust, moisture and other substances, thereby ensuring the effective operation of the second screw mixing module 2.

[0045] Optionally, the surface of the second housing 21 may be provided with an openable sealing cover. When it is necessary to replace, clean or repair the components inside the second screw mixing module 2, the operator can open the sealing cover without disassembling the entire second housing 21, thereby shortening the maintenance time and reducing the difficulty of operation.

[0046] The interior of the second housing 21 forms a second mixing chamber 21a to accommodate the pre-mixed material. The second housing 21 is provided with a second inlet and a second outlet. The second inlet and the second outlet are connected to the second mixing chamber 21a. The second inlet is connected to the first outlet. The pre-mixed material enters the second mixing chamber 21a after passing through the first outlet and the second inlet.

[0047] The second inlet and the second outlet are arranged at intervals along the first horizontal direction X. The second mixing component 22 is located in the second mixing chamber 21a. The second mixing component 22 is used to push the pre-mixed material to move along the first horizontal direction X to the second outlet. During the pushing process, the pre-mixed material is mixed a second time. After being pushed to the second outlet, the material after the second mixing can be discharged from the second mixing chamber 21a under the action of gravity.

[0048] Optionally, the second mixing component 22 may be a spiral mixing structure, or it may be a vibration structure or other structure that can perform secondary mixing of materials during the process of pushing the materials to move. This application embodiment does not limit this.

[0049] Thus, the material mixing mechanism 100 provided in this embodiment can continuously mix materials. Materials enter the first mixing chamber 11a through the first inlet and are initially mixed by the first mixing component 12. After initial mixing, materials enter the second mixing chamber 21a through the second inlet and are then mixed a second time by the second mixing component 22. After the second mixing is completed, the materials are discharged through the second outlet. There is no need for interruption or transfer to other devices between the initial and secondary mixing processes, achieving continuous mixing and improving mixing efficiency. Simultaneously, the absence of material transfer processes reduces material loss.

[0050] Please refer to Figure 4, which is a schematic diagram of the structure of the first mixing assembly 12 provided in an embodiment of this application. In some embodiments, the first mixing assembly 12 further includes: a first screw 121, which is rotatably connected to the first housing 11 and located in the first mixing chamber 11a, and the first screw 121 extends along the first horizontal direction X; a second screw 122, which is rotatably connected to the first housing 11 and located in the first mixing chamber 11a, and the second screw 122 extends along the first horizontal direction X; the first screw 121 and the second screw 122 are arranged at intervals along the second horizontal direction Y; the driving assembly 3 can drive the first screw 121 and the second screw 122 to rotate.

[0051] Specifically, after the material enters the first mixing chamber 11a through the first feed inlet, it can contact the first screw 121 and the second screw 122. The first screw 121 and the second screw 122 can rotate in opposite directions under the drive of the drive assembly 3, so that the material is mixed by the opposite rotation of the first screw 121 and the second screw 122.

[0052] Furthermore, the structure of the first screw 121 and the second screw 122 can push the material along the first horizontal direction X to the first discharge port during rotation, and achieve mixing of the material during the process of pushing the material. The pre-mixed material can be discharged from the first discharge port under the action of gravity.

[0053] Referring to Figure 4, in some embodiments, the first screw 121 includes: a first rotating shaft 1211 located in the first mixing chamber 11a, the first rotating shaft 1211 being rotatably connected to the first housing 11, the first rotating shaft 1211 extending along the first horizontal direction X, and the first rotating shaft 1211 being connected to the drive assembly 3; and a first threaded member 1212 detachably sleeved on the first rotating shaft 1211, the outer surface of the first threaded member 1212 having a first thread structure, and the first threaded member 1212 being able to rotate with the first rotating shaft 1211 to push the material to move along the extension direction of the first rotating shaft 1211 through the first thread structure.

[0054] The second screw 122 includes: a second rotating shaft 1221 located in the first mixing chamber 11a, the second rotating shaft 1221 being rotatably connected to the first housing 11, the second rotating shaft 1221 extending along the first horizontal direction X, and the second rotating shaft 1221 being connected to the drive assembly 3; and a second threaded member 1222 detachably sleeved on the second rotating shaft 1221, the outer surface of the second threaded member 1222 having a second thread structure, the second threaded member 1222 being able to rotate with the second rotating shaft 1221 to push the material to move along the extension direction of the second rotating shaft 1221 through the second thread structure, the first thread structure and the second thread structure having opposite rotation directions, and the first rotating shaft 1211 and the second rotating shaft 1221 rotating in opposite directions.

[0055] The first rotating shaft 1211 is disposed in the first mixing chamber 11a and extends along the first horizontal direction X. The first rotating shaft 1211 is rotatably connected to the first housing 11 to avoid friction or obstruction between the first rotating shaft 1211 and the first housing 11, so as to ensure that the first rotating shaft 1211 can rotate freely under the drive of the drive assembly 3, and also to ensure the stability of the first rotating shaft 1211.

[0056] The first threaded component 1212 is disposed on the first rotating shaft 1211 and can rotate with the first rotating shaft 1211. When the drive assembly 3 is activated and drives the first rotating shaft 1211 to rotate, the first threaded component 1212 also rotates with the first rotating shaft 1211, thereby causing the first threaded structure of the first screw 121 to contact the material and mix or stir the material in the first mixing chamber 11a. The first threaded component 1212 not only improves the mixing efficiency of the material, but also ensures the uniformity of the material mixing.

[0057] The second rotating shaft 1221 is disposed in the first mixing chamber 11a and extends along the first horizontal direction X. The second rotating shaft 1221 is rotatably connected to the first housing 11 to avoid friction or obstruction between the second rotating shaft 1221 and the first housing 11, so as to ensure that the second rotating shaft 1221 can rotate freely under the drive of the drive assembly 3, and also to ensure the stability of the second rotating shaft 1221.

[0058] The second threaded component 1222 is disposed on the second rotating shaft 1221 and can rotate with the second rotating shaft 1221. When the drive assembly 3 is activated and drives the second rotating shaft 1221 to rotate, the second threaded component 1222 also rotates with the second rotating shaft 1221, thereby causing the second threaded structure of the second screw 122 to contact the material and mix or stir the material in the first mixing chamber 11a. The arrangement of the second threaded component 1222 not only improves the mixing efficiency of the material, but also ensures the uniformity of the material mixing.

[0059] Please refer to Figure 4. In some embodiments, there are multiple first threaded parts 1212, which are sequentially sleeved on the first rotating shaft 1211. The first thread structure of the multiple first threaded parts 1212 may be the same or different. There are multiple second threaded parts 1222, which are sequentially sleeved on the second rotating shaft 1221. The second thread structure of the multiple second threaded parts 1222 may be the same or different.

[0060] Furthermore, multiple first threaded parts 1212 are arranged sequentially along the direction from the first feed port to the first discharge port, so that after the material enters the mixing component from the first feed port, it will first pass through one first threaded part 1212, then through another first threaded part 1212, and finally be discharged from the first discharge port, thereby gradually achieving the ideal mixing effect during the mixing process.

[0061] In this way, the first threaded component 1212 achieves synergistic effect through different thread pitches, realizing effective mixing of materials, improving mixing efficiency, and ensuring mixing quality. At the same time, through the reasonable arrangement of multiple first threaded components 1212, the materials can gradually reach the ideal mixing state during the mixing process.

[0062] Furthermore, the pitch, tooth profile, and tilt angle of the multiple first threaded parts 1212 can be different. Since the first threaded parts 1212 are detachably sleeved on the first rotating shaft 1211, in actual production, different first threaded parts 1212 can be matched with different materials to achieve an ideal mixing state.

[0063] In some embodiments, the outer surface of the first rotating shaft 1211 is provided with a first spline, and the inner circumferential surface of the first threaded member 1212 is provided with a first spline groove corresponding to the first spline, and the first spline and the first spline groove are connected in a mating manner.

[0064] The outer surface of the first rotating shaft 1211 is provided with a first spline, and correspondingly, the inner circumferential surface of the first threaded component 1212 is provided with a first spline groove that matches the first spline. The first threaded component 1212 can achieve a stable connection with the first rotating shaft 1211 through the engagement of the first spline and the first spline groove. The first spline and the first spline groove have load-bearing capacity and stability, and also ensure transmission stability, making the transmission between the first rotating shaft 1211 and the first threaded component 1212 more efficient and stable.

[0065] Please refer to Figure 5, which is a schematic diagram of the material mixing mechanism 100 provided in an embodiment of this application. In some embodiments, the second mixing component 22 further includes: a third screw 221, which is rotatably connected to the second housing 21 and located in the second mixing chamber 21a, and the third screw 221 extends along the first horizontal direction X; a fourth screw 222, which is rotatably connected to the second housing 21 and located in the second mixing chamber 21a, and the fourth screw 222 extends along the first horizontal direction X; the fourth screw 222 and the third screw 221 are arranged at intervals along the second horizontal direction Y; the driving component 3 can drive the third screw 221 and the fourth screw 222 to rotate.

[0066] Specifically, after the material enters the second mixing chamber 21a through the second feed inlet, it can contact the third screw 221 and the fourth screw 222. The third screw 221 and the fourth screw 222 can rotate in opposite directions under the drive of the drive assembly 3, so that the material is mixed by the reverse rotation of the third screw 221 and the fourth screw 222.

[0067] Furthermore, the structure of the third screw 221 and the fourth screw 222 can push the pre-mixed material along the first horizontal direction X to the second discharge port during rotation, and realize secondary mixing of the material during the process of pushing the pre-mixed material. The material after secondary mixing can be discharged from the second discharge port under the action of gravity.

[0068] Please refer to Figures 2, 3, and 6. Figure 6 is a cross-sectional structural schematic diagram of the material mixing device 200 provided in an embodiment of this application. In some embodiments, the drive assembly 3 includes: a first gear assembly 31 disposed on the first screw 121 and the third screw 221, which can drive the first screw 121 and the third screw 221 to rotate synchronously; a second gear assembly 32 disposed on the first screw 121 and the second screw 122, which can drive the first screw 121 and the second screw 122 to rotate synchronously; a third gear assembly 33 disposed on the third screw 221 and the fourth screw 222, which can drive the third screw 221 and the fourth screw 222 to rotate synchronously; and a drive member 34 connected to the first screw 121, which can drive the first screw 121 to rotate.

[0069] The drive assembly 3 includes a first gear assembly 31, a second gear assembly 32, a third gear assembly 33, and a drive member 34. The first gear assembly 31 is disposed on the first screw 121 and the third screw 221. When the drive member 34 drives the first screw 121 to rotate, the first gear assembly 31 will also rotate with the first screw 121 and drive the third screw 221 to rotate synchronously.
