Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] The mixing device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0036] Referring to Figures 1 and 3, a mixing device according to some embodiments of this application includes a feeding cylinder 1, a conveying pipe 2, a mixing cylinder 3, and a striking mechanism 4. The conveying pipe 2 connects the feeding cylinder 1 and the mixing cylinder 3, and is used to input the material in the feeding cylinder 1 into the mixing cylinder 3. The striking mechanism 4 includes a striking component 41, a base 42, and a driving component 43. The base 42 is disposed opposite to the conveying pipe 2. The striking component 41 is slidably connected to the base 42. The driving component 43 is disposed in the base 42 and has a cam 44. The driving component 43 is used to drive the cam 44 to move, so as to push the striking component 41 to strike the conveying pipe 2 through the cam 44.

[0037] In the embodiments of this application, the conveying pipe 2 connects the feeding cylinder 1 and the mixing cylinder 3. The material in the feeding cylinder 1 enters the mixing cylinder 3 through the conveying pipe 2. The base 42 is arranged opposite to the conveying pipe 2. The striking component 41 is slidably connected to the base 42. A driving component 43 is provided in the base 42. A cam 44 is provided in the driving component 43. The driving component 43 drives the cam 44 to move, thereby pushing the striking component 41 to strike the conveying pipe 2. The striking causes the conveying pipe 2 to vibrate, shaking off the material blocking the conveying pipe 2 so as to better discharge the material. In this way, the blockage of the conveying pipe 2 is avoided, and the material enters the mixing cylinder 3 in time for mixing, thereby improving the mixing efficiency of the mixing device.

[0038] In practical applications, the feeding cylinder 1, the conveying pipe 2, and the mixing cylinder 3 are connected in sequence along the vertical direction. The conveying pipe 2 connects the feeding cylinder 1 and the mixing cylinder 3. The user puts the material into the feeding cylinder 1 and then into the mixing cylinder 3 through the conveying pipe 2 for mixing. However, since the inner diameter of the conveying pipe 2 is smaller than that of the feeding cylinder 1, it is easy to cause blockage when a large amount of material is put in. Therefore, a knocking mechanism 4 is set at the relative position of the conveying pipe 2 to knock the conveying pipe 2, thereby causing the conveying pipe 2 to vibrate and shake off the blocked material.

[0039] Understandably, the mixing device in this application can be used for mixing raw materials in lithium battery production processes. The materials are generally in powder form, which makes them prone to clogging when entering the conveying pipe 2 from the feeding cylinder 1. Of course, it can also be applied to other scenarios, which are not limited here.

[0040] Specifically, the striking mechanism 4 is arranged opposite to the conveying pipe 2 along the axis perpendicular to the conveying pipe 2. The base 42 of the striking mechanism 4 can be connected to the feeding cylinder 1 or the mixing cylinder 3. Those skilled in the art can make the setting according to their needs, and this application does not limit it.

[0041] The striking component 41 is slidably connected to the base 42, and the driving component 43 drives the cam 44 to push the striking component 41 to strike the feed pipe 2. The cam 44 has a relatively far end and a near end from its rotation center. Therefore, during the rotation of the cam 44, it will intermittently push the striking component 41 to strike the feed pipe 2.

[0042] Furthermore, the striking component 41 is pushed by the cam 44 to strike the feed tube 2. Alternatively, the distal end of the cam 44 can directly push the striking component 41 to slide toward the feed tube 2 to strike the feed tube 2. Since the striking component 41 needs to generate a large impact with the feed tube 2 when striking the feed tube 2, in order to avoid the situation where the cam 44 pushes the striking component 41 and the feed tube 2 to be limited and locked in the direction perpendicular to the axis of the feed tube 2, an elastic telescopic part can be provided at the part of the striking component 41 that contacts the feed tube 2.

[0043] Referring to Figures 3 and 4, according to some embodiments of this application, the striking component 41 includes a first elastic member 411, a sliding member 412, and a striking member 413. The base 42 is provided with a groove 421, and the sliding member 412 is slidably connected in the groove 421. Along the sliding direction of the sliding member 412, the first elastic member 411 is disposed between the sliding member 412 and the base 42, and the sliding member 412 is elastically connected to the base 42 through the first elastic member 411. The striking member 413 is connected to the side of the sliding member 412 facing the feed pipe 2. The cam 44 is disposed opposite to the sliding member 412. The driving component 43 is used to drive the cam 44 to move, so that the cam 44 pushes the sliding member 412 to drive the striking member 413 to reciprocate between the base 42 and the feed pipe 2 to strike the feed pipe 2.

[0044] In this embodiment, the base 42 is provided with a groove 421, and the slider 412 is slidably connected in the groove 421. Along the sliding direction of the slider 412, the first elastic member 411 is disposed between the slider 412 and the base 42, and the slider 412 is elastically connected to the base 42 through the first elastic member 411.

[0045] As a result, when the sliding member 412 is pushed by the cam 44 to slide away from the conveying pipe 2, the first elastic member 411 is compressed and deformed to store force; when the cam 44 separates from the sliding member 412 at the farthest point from the center of rotation, the first elastic member 411 rebounds and pushes the sliding member 412 to slide towards the conveying pipe 2, so as to drive the striking member 413 to strike the conveying pipe 2. This process is repeated. Under the action of the cam 44 and the first elastic member 411, the striking member 413 reciprocates between the base 42 and the conveying pipe 2 to strike the conveying pipe 2.

[0046] Furthermore, by striking the conveying pipe 2, the material blocking the conveying pipe 2 is shaken off, so that the material can be discharged more effectively. In this way, the blockage of the conveying pipe 2 is avoided, and the material can enter the mixing cylinder 3 in time for mixing, thereby improving the mixing efficiency of the mixing device.

[0047] Understandably, the first elastic element 411 rebounds and pushes the sliding element 412 to drive the striking element 413 to strike the conveying pipe 2, so that the striking element 413 has a greater impulse when striking the conveying pipe 2, the vibration amplitude generated by the conveying pipe 2 is greater, and the material blocked in the conveying pipe 2 is easier to fall out.

[0048] In a specific application, the cam 44 is positioned relative to the slider 412, such that the farthest point of the cam 44 from the rotation center pushes the slider 412 to move away from the feed pipe 2, thereby compressing the first elastic member 411; when the farthest point of the cam 44 from the rotation center separates from the slider 412, the first elastic member 411 rebounds and pushes the slider 412 to slide towards the feed pipe 2, thereby driving the striking member 413 to strike the feed pipe 2.

[0049] Referring to Figure 3, in some embodiments of this application, the slider 412 includes a slider 4121 and a fixed plate 4122. The slider 4121 is slidably connected in the groove 421. The fixed plate 4122 is disposed on the side of the slider 4121 facing the feed pipe 2 and is connected to the slider 4121. The striking member 413 is connected to the fixed plate 4122. The cam 44 is disposed between the slider 4121 and the fixed plate 4122. The first elastic member 411 is disposed between the fixed plate 4122 and the base 42. The fixed plate 4122 is elastically connected to the base 42 through the first elastic member 411. The driving assembly 43 is used to drive the cam 44 to move so that the cam 44 pushes the slider 4121 to move.

[0050] In this embodiment, the slider 4121 is slidably connected to the groove 421, the fixing plate 4122 is disposed on the side of the slider 4121 facing the feed pipe 2, the fixing plate 4122 is connected to the slider 4121, the striking member 413 is connected to the fixing plate 4122, the cam 44 is disposed between the slider 4121 and the fixing plate 4122, the first elastic member 411 is disposed between the fixing plate 4122 and the base 42, and the fixing plate 4122 is elastically connected to the base 42 through the first elastic member 411.

[0051] When the drive assembly 43 drives the cam 44 to rotate, the farthest end from the rotation center, when rotating to a direction away from the feed pipe 2, pushes the slider 4121 to slide in a direction away from the feed pipe 2, thereby compressing the first elastic member 411. The first elastic member 411 elastically connects the fixed plate 4122 and the base 42, so that the first elastic member 411 has a longer compression stroke and a larger impulse when rebounding, so as to drive the striking member 413 to strike the feed pipe 2.

[0052] Understandably, the first elastic element 411 can also be disposed between the slider 4121 and the base 42, but the first elastic element 411 needs to have a larger elastic coefficient so that the first elastic element 411 stores higher potential energy when compressed, and has a larger impulse when it rebounds and pushes the striking element 413 to strike the feed tube.

[0053] In a specific application, the slider 4121 has a sidewall corresponding to the fixed plate 4122, so that the cam 44 pushes the sidewall corresponding to the slider 4121 at the farthest point from the rotation center to compress the first elastic member 411. Therefore, the slider 4121 can be "C-shaped" or "L-shaped". Those skilled in the art can set it according to actual needs, and this application does not limit it.

[0054] Understandably, when the striking element 413 strikes the feed tube 2, the first elastic element 411 rebounds to its free length; when the cam 44 pushes the sliding element 4121 to slide in a direction away from the feed tube 2, the first elastic element 411 is compressed; thus, when the first elastic element 411 rebounds, it can convert all the stored potential energy into the kinetic energy of the sliding element 412, so as to drive the striking element 413 to strike the feed tube 2.

[0055] Referring to Figures 2 and 4, the drive assembly 43 includes a first drive member 431 and a first rotating shaft 432. The first drive member 431 is mounted in the base 42, the first rotating shaft 432 is connected to the first drive member 431, and the cam 44 is connected to the first rotating shaft 432. The first drive member 431 is used to drive the first rotating shaft 432 to rotate the cam 44 so that the farthest end of the cam 44 from the first rotating shaft 432 is close to or away from the side of the slider 412 away from the striking member 413.

[0056] In this embodiment, the first driving member 431 is installed inside the base 42, the first rotating shaft 432 is connected to the first driving member 431, and the cam 44 is connected to the first rotating shaft 432. The first driving member 431 drives the first rotating shaft 432 to rotate the cam 44, so that the farthest end of the cam 44 from the first rotating shaft 432 is closer to or farther away from the slider 412 away from the striking member 413. Thus, when the first driving member 431 drives the first rotating shaft 432 to rotate the cam 44, when the farthest end of the cam 44 from the first rotating shaft 432 is closer to the slider 412 away from the striking member 413, it pushes the slider 412 to slide away from the conveying pipe 2, thereby pressing... The first elastic element 411 is compressed and stores elastic potential energy. When the cam 44 is at its farthest point from the first rotating shaft 432, away from the sliding element 412 and away from the striking element 413, the first elastic element 411 rebounds, pushing the sliding element 412 to slide towards the conveying pipe 2, converting the elastic potential energy of the first elastic element 411 into kinetic energy, which drives the striking element 413 to strike the conveying pipe 2. This process is repeated intermittently, causing the conveying pipe 2 to vibrate and dislodge any blocked material, thus improving the material discharge efficiency. This prevents blockage of the conveying pipe 2 and allows the material to enter the mixing cylinder 3 in a timely manner for mixing, thereby improving the mixing efficiency of the mixing device.

[0057] In a specific application, the output end of the first driving member 431 is connected to the first rotating shaft 432. The end of the first rotating shaft 432 away from the first driving member 431 is connected to the cam 44. The cam 44 is located between the sliding member 412 and the striking member 413. When the first driving member 431 works, it drives the cam 44 to rotate, so that the farthest end of the cam 44 from the first rotating shaft 432 is closer to or farther away from the sliding member 412 away from the striking member 413. During this process, the first elastic member 411 stores energy or rebounds. Thus, under the combined action of the cam 44 and the first elastic member 411, the striking member 413 reciprocates between the base 42 and the conveying pipe 2 to strike the conveying pipe 2.

[0058] Understandably, the first driving component 431 can be a motor, a cylinder, or a hydraulic cylinder, and those skilled in the art can select one according to their needs. This application does not impose any restrictions on this.

[0059] Referring to Figures 2 and 5, in some embodiments of this application, a dustproof component 5 is also included. A feeding port 11 is provided on the side of the feeding cylinder 1 away from the feeding pipe 2. The dustproof component 5 is located at the feeding port 11 and is rotatably connected to the feeding cylinder 1. The dustproof component 5 can rotate relative to the feeding cylinder 1 to block or unblock the feeding port 11.

[0060] In this embodiment, a feeding port 11 is provided on the side of the feeding cylinder 1 away from the conveying pipe 2. A dustproof component 5 is provided at the feeding port. The dustproof component 5 is rotatably connected to the feeding cylinder 1, thereby blocking or unblocking the feeding port 11 to prevent material dust in the feeding cylinder 1 from escaping, causing harm to the operators and polluting the working environment.

[0061] In practical applications, since the materials are generally in powder form, when operators put the materials into the feeding cylinder 1 through the feeding port 11, it is easy to generate flying dust, which can be inhaled by the operators and affect their health. Therefore, a dustproof component 5 is installed at the feeding port 11. The dustproof component 5 is rotatably connected to the feeding cylinder 1. In this way, when the operator puts the materials into the feeding cylinder 1, the dustproof component 5 releases the cover on the feeding port 11; when the feeding is finished, the dustproof component 5 covers the feeding port 11 again to prevent the flying dust from escaping.

[0062] Referring to Figures 2 and 5, in some embodiments of this application, the dustproof component 5 includes a second rotating shaft 51, a second elastic element 52, and a baffle 53. The second rotating shaft 51 is located at the feeding port 11 and connected to the feeding cylinder 1. The baffle 53 is connected to the second rotating shaft 51. The second elastic element 52 is located between the second rotating shaft 51 and the feeding cylinder 1. One end of the second elastic element 52 is connected to the feeding cylinder 1, and the other end is connected to the baffle 53. The baffle 53 can rotate relative to the feeding cylinder 1 to block or unblock the feeding port 11.

[0063] In this embodiment, the second rotating shaft 51 is located at the feeding port 11 and connected to the feeding cylinder 1. The baffle 53 is connected to the second rotating shaft 51. The second elastic member 52 is located between the second rotating shaft 51 and the feeding cylinder 1. One end of the second elastic member 52 is connected to the feeding cylinder 1, and the other end is connected to the baffle 53. The baffle 53 can rotate relative to the feeding cylinder 1. Thus, when the operator feeds material into the feeding port 11, the baffle 53 releases its obstruction of the feeding port 11 under the action of the material's own weight, allowing the material to be fed into the feeding cylinder 1. When the material feeding is completed, the second elastic member 52 rebounds, causing the baffle 53 to rotate and reset, thus obstructing the feeding port 11.

[0064] Optionally, the second rotating shaft 51 is rotatably connected to the feeding cylinder 1, the baffle 53 is fixedly connected to the second rotating shaft 51, and the second elastic member 52 is disposed between the second rotating shaft 51 and the feeding cylinder 1. One end of the second elastic member 52 is connected to the feeding cylinder 1, and the other end is connected to the second rotating shaft 51. In this way, the second rotating shaft 51 rotates relative to the feeding cylinder 1, thereby driving the baffle 53 to rotate relative to the feeding cylinder 1, so as to block or unblock the feeding port 11.

[0065] Optionally, the second rotating shaft 51 is fixedly connected to the feeding cylinder 1, the baffle 53 is rotatably connected to the second rotating shaft 51, and the second elastic member 52 is disposed between the second rotating shaft 51 and the feeding cylinder 1. One end of the second elastic member 52 is connected to the feeding cylinder 1, and the other end is connected to the baffle 53. In this way, the baffle 53 rotates relative to the feeding cylinder 1 to block or unblock the feeding port 11.

[0066] Referring to Figures 2 and 5, in some embodiments of this application, the dustproof component 5 further includes a partition 54, which is disposed at the feeding port 11 and connected to the side wall of the feeding port 11, dividing the feeding port 11 into at least two sub-feeding ports 111, and each sub-feeding port 111 is provided with a dustproof component 5.

[0067] In this embodiment, a partition 54 is also provided at the feeding port 11. The partition 54 is connected to the side wall of the feeding port 11, dividing the feeding port 11 into at least two sub-feeding ports 111. Each sub-feeding port 111 is provided with a dustproof component 5. This avoids the situation where, when a dustproof component 5 is provided, the baffle 53 is too heavy, requiring a second elastic element 52 with a high elastic coefficient. Furthermore, when only a small amount of material remains, the baffle 53 rebounds under the action of the second elastic element 52, preventing all the material from being fed into the feeding cylinder 1.

[0068] In specific applications, the selection of the second elastic element 52 is related to the weight of the baffle 53 itself, so as to ensure that the baffle 53 can rotate to block the feeding port 11 under the action of the second elastic element 52.

[0069] Understandably, a partition 54 is provided at the feeding port 11 to divide the feeding port 11 into at least two sub-feeding ports 111. On the one hand, this facilitates the selection of the second elastic element 52 and the baffle 53. On the other hand, the at least two sub-feeding ports 111 make it easier to feed materials into the feeding cylinder 1.

[0070] Referring to Figures 3 and 5, in some embodiments of this application, the dustproof assembly 5 further includes a material blocking member 55, one end of which is connected to the feeding cylinder 1, and the other end extends to the side of the second rotating shaft 51 away from the feeding pipe 2, so as to block the gap between the second rotating shaft 51 and the inner wall of the feeding cylinder 1.

[0071] In this embodiment, since the second rotating shaft 51 is connected to the feeding cylinder 1, a gap will inevitably be formed between the second rotating shaft 51 and the feeding cylinder 1 along the axial direction perpendicular to the second rotating shaft 51. One end of the baffle 55 is connected to the feeding cylinder 1, and the other end extends to the side of the second rotating shaft 51 away from the conveying pipe 2, thereby blocking the gap between the second rotating shaft 51 and the inner wall of the feeding cylinder 1 to prevent the material powder in the feeding cylinder 1 from escaping from the gap, thus improving the safety of the operator.

[0072] Understandably, the baffle 55 can be integrally formed with the feeding cylinder 1, or it can be bonded, screwed, or snapped onto the side wall of the feeding cylinder 1. Those skilled in the art can choose according to their needs, and this application does not impose any restrictions on this.

[0073] In specific applications, the end of the baffle 55 facing the second rotating shaft 51 is provided with an arc surface that matches the surface of the second rotating shaft 51, thereby further improving the shielding of the gap between the second rotating shaft 51 and the inner wall of the feeding cylinder 1.

[0074] Referring to Figure 6, in some embodiments of this application, the mixing device further includes a second driving member 61, a third rotating shaft 62, and a stirring member 63. The mixing cylinder 3 is provided with a mixing chamber 31. The second driving member 61 is installed in the mixing cylinder 3. The third rotating shaft 62 is connected to the second driving member 61 and extends into the mixing chamber 31. The stirring member 63 is connected to the third rotating shaft 62. The second driving member 61 is used to drive the third rotating shaft 62 to rotate, so as to drive the stirring member 63 to stir the material in the mixing chamber 31.

[0075] In this embodiment, a mixing chamber 31 is provided inside the mixing cylinder 3. A second driving member 61 is installed in the mixing cylinder 3. A third rotating shaft 62 is connected to the second driving member 61 and extends into the mixing chamber 31. A stirring member 63 is connected to the third rotating shaft 62. The second driving member 61 drives the third rotating shaft 62 to rotate, thereby driving the stirring member 63 to stir the material in the mixing chamber 31, so as to complete the mixing of the input material.

[0076] In practical applications, the mixing cylinder 3 is also provided with a discharge port on the side opposite to the conveying pipe 2, and the material after mixing is completed flows out from the discharge port.

[0077] Referring to Figure 6, in some embodiments of this application, the mixing device further includes at least two connecting members 71 and a scraper 72. Along the axial direction of the third rotating shaft 62, at least two connecting members 71 are spaced apart on the third rotating shaft 62. One end of the connecting member 71 is connected to the third rotating shaft 62, and the other end is connected to the scraper 72. The scraper 72 is at least partially in contact with the inner wall of the mixing chamber 31. The second driving member 61 is also used to drive the third rotating shaft 62 to rotate, so as to drive the scraper 72 to scrape off the material attached to the inner wall of the mixing chamber 31.

[0078] In this embodiment, at least two connecting members 71 are spaced apart on the third rotating shaft 62 along its axial direction. One end of the connecting member 71 is connected to the third rotating shaft 62, and the other end is connected to the scraper 72. The scraper 72 is at least partially in contact with the inner wall of the mixing chamber 31. Thus, when the second driving member 61 drives the third rotating shaft 62 to rotate, the stirring member 63 mixes the material in the mixing chamber 31. At the same time, it drives the scraper 72 to scrape off the material attached to the inner wall of the mixing chamber 31. This ensures that all the material is fully mixed and prevents the material from adhering to the inner wall of the mixing chamber 31, which would affect the subsequent use of the mixing device.

[0079] Understandably, at least two connectors 71 are spaced apart on the third rotating shaft 62. One end of each connector 71 is connected to the third rotating shaft 62, and the other end is connected to the scraper 72. In the vertical direction, a connector 71 is connected to each end of a scraper 72, so that the scraper 72 can stably scrape off the material adhering to the inner wall of the mixing chamber 31.

[0080] Referring to Figure 6, in some embodiments of this application, the scraper 72 has an arc surface on the side facing the inner wall of the mixing chamber 31, and the arc surface is at least partially in contact with the inner wall of the mixing chamber 31.

[0081] In this embodiment, the scraper 72 has an arc surface on the side facing the inner wall of the mixing chamber 31. The arc surface is at least partially in contact with the inner wall of the mixing chamber 31, thereby reducing the friction between the scraper 72 and the inner wall of the mixing chamber 31 and improving the efficiency of scraping off the attached material.

[0082] Understandably, the scraper 72 has an arc surface on the side facing the inner wall of the mixing chamber 31, so that the scraper 72 and the mixing chamber 31 form a line contact, thereby reducing the friction between the scraper 72 and the mixing chamber 31.

[0083] Although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the claims and their equivalents.
