[0033] The following will, with reference to the drawings, through specific embodiments and their application scenarios, provide a detailed description of a mixing device provided by an embodiment of the present application.

[0034] Reference Figure 1 and Figure 3 , a mixing device according to some embodiments of the present application includes a feeding cylinder 1, a feeding pipe 2, a mixing cylinder 3, and a knocking mechanism 4. The feeding pipe 2 communicates with 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 knocking mechanism 4 includes a knocking component 41, a base 42, and a driving component 43. The base 42 is disposed opposite to the feeding pipe 2. The knocking component 41 is slidably connected to the base 42. The driving component 43 is disposed in the base 42. A cam 44 is provided in the driving component 43. The driving component 43 is used to drive the cam 44 to move so as to push the knocking component 41 to knock the feeding pipe 2.

[0035] In an embodiment of the present application, the feeding pipe 2 communicates with the feeding cylinder 1 and the mixing cylinder 3. The material in the feeding cylinder 1 enters the mixing cylinder 3 through the feeding pipe 2. The base 42 is disposed opposite to the feeding pipe 2. The knocking 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 knocking component 41 to knock the feeding pipe 2. By knocking, the feeding pipe 2 is caused to vibrate, and the blocked material in the feeding pipe 2 is shaken off to facilitate better feeding. In this way, the blockage of the feeding pipe 2 is avoided, enabling the material to enter the mixing cylinder 3 in time for mixing, thereby improving the mixing efficiency of the mixing device.

[0036] In a specific application, along the vertical direction, the feeding cylinder 1, the material conveying pipe 2, and the mixing cylinder 3 are connected in sequence. The material conveying pipe 2 communicates with the feeding cylinder 1 and the mixing cylinder 3. The user puts the material into the feeding cylinder 1 and inputs it into the mixing cylinder 3 through the material conveying pipe 2 for mixing. Since the inner diameter of the material conveying pipe 2 is smaller than the size of the feeding cylinder 1, when more materials are put in, it is easy to cause blockage. Therefore, a knocking mechanism 4 is arranged at the relative position of the material conveying pipe 2 to knock on the material conveying pipe 2, so that the material conveying pipe 2 vibrates to shake off the blocked materials.

[0037] It can be understood that the mixing device in this application can be used for raw material mixing in the lithium battery production process. Its materials are generally in powder form, making it easy for the materials to be blocked when entering the material conveying pipe 2 from the feeding cylinder 1. Of course, it can also be applied to other scenarios, which are not limited in this application.

[0038] Specifically, along the direction perpendicular to the axis of the material conveying pipe 2, the knocking mechanism 4 is arranged opposite to the material conveying pipe 2. The base 42 of the knocking mechanism 4 can be connected to the feeding cylinder 1 or the mixing cylinder 3. Those skilled in the art can set it according to needs, and this application does not limit this.

[0039] Among them, the knocking component 41 is slidably connected to the base 42, and the driving component 43 drives the cam 44 to push the knocking component 41 to knock on the material conveying pipe 2. The cam 44 has a relative distal end and proximal end from its rotation center. Therefore, during the rotation of the cam 44, it will intermittently push the knocking component 41 to knock on the material conveying pipe 2.

[0040] Furthermore, when the knocking component 41 is pushed by the cam 44 to knock on the material conveying pipe 2, it can be that the distal end of the cam 44 directly pushes the knocking component 41 to slide towards the material conveying pipe 2 to knock on the material conveying pipe 2. Since a large impact needs to be generated between the knocking component 41 and the material conveying pipe 2 when knocking on the material conveying pipe 2, in order to avoid the situation of limit locking in the direction perpendicular to the axis of the material conveying pipe 2 when the cam 44 pushes the knocking component 41 and the material conveying pipe 2, an elastic telescopic part can be arranged at the contact part between the knocking component 41 and the material conveying pipe 2.

[0041] Reference Figure 3 and Figure 4, according to some embodiments of the present application, the knocking component 41 includes a first elastic member 411, a sliding member 412, and a knocking member 413. The base 42 is provided with a chute 421. The sliding member 412 is slidably connected within the chute 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. The sliding member 412 is elastically connected to the base 42 through the first elastic member 411; the knocking 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 assembly 43 is used to drive the cam 44 to move, so that the cam 44 pushes the sliding member 412 to drive the knocking member 413 to reciprocate between the base 42 and the feed pipe 2 to knock the feed pipe 2.

[0042] In the embodiments of the present application, the base 42 is provided with a chute 421. The sliding member 412 is slidably connected within the chute 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. The sliding member 412 is elastically connected to the base 42 through the first elastic member 411.

[0043] Thus, when the sliding member 412 is pushed by the cam 44 to slide away from the feed pipe 2, the first elastic member 411 is compressed and deformed to store energy; when the farthest end of the cam 44 from the rotation center is separated from the sliding member 412, the first elastic member 411 rebounds to push the sliding member 412 to slide towards the feed pipe 2, so as to drive the knocking member 413 to knock the feed pipe 2. In this way, the knocking member 413 reciprocates between the base 42 and the feed pipe 2 to knock the feed pipe 2 under the action of the cam 44 and the first elastic member 411.

[0044] Furthermore, through knocking, the feed pipe 2 vibrates, and the blocked materials in the feed pipe 2 are shaken off, so as to facilitate better feeding; in this way, the blockage of the feed pipe 2 is avoided, so that the materials can enter the mixing cylinder 3 in time for mixing, thereby improving the mixing efficiency of the mixing device.

[0045] It can be understood that the first elastic member 411 rebounds to push the sliding member 412, so as to drive the knocking member 413 to knock the feed pipe 2, so that when the knocking member 413 knocks the feed pipe 2, it has a greater impulse, the vibration amplitude of the feed pipe 2 is greater, and the blocked materials in the feed pipe 2 are more likely to fall off.

[0046] In a specific application, the cam 44 is disposed relative to the sliding member 412, so that the farthest end of the cam 44 from the rotation center pushes the sliding member 412 to move away from the feed pipe 2 to compress the first elastic member 411; when the farthest end of the cam 44 from the rotation center is separated from the sliding member 412, the first elastic member 411 rebounds to push the sliding member 412 to slide towards the feed pipe 2, so as to drive the knocking member 413 to knock the feed pipe 2.

[0047] ReferenceFigure 3 In some embodiments of the present application, the sliding member 412 includes a slider 4121 and a fixing plate 4122. The slider 4121 is slidably connected to the chute 421. The fixing plate 4122 is disposed on the side of the slider 4121 facing the material conveying pipe 2. The fixing plate 4122 is connected to the slider 4121. The knocking 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. The fixing 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.

[0048] In the embodiments of the present application, the slider 4121 is slidably connected to the chute 421. The fixing plate 4122 is disposed on the side of the slider 4121 facing the material conveying pipe 2. The fixing plate 4122 is connected to the slider 4121. The knocking 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. The fixing plate 4122 is elastically connected to the base 42 through the first elastic member 411.

[0049] Thus, when the driving assembly 43 drives the cam 44 to rotate, when the farthest end from the rotation center rotates in the direction away from the material conveying pipe 2, it pushes the slider 4121 to slide in the direction away from the material conveying pipe 2, thereby compressing the first elastic member 411. The first elastic member 411 elastically connects the fixing plate 4122 and the base 42, so that the first elastic member 411 has a longer compression stroke and has a greater impulse when rebounding to drive the knocking member 413 to knock on the material conveying pipe 2.

[0050] It can be understood that the first elastic member 411 can also be disposed between the slider 4121 and the base 42, but the first elastic member 411 needs to have a greater elastic coefficient so that the first elastic member 411 stores higher potential energy when compressed and has a greater impulse when rebounding to push the knocking member 413 to knock on the material conveying pipe.

[0051] In a specific application, the slider 4121 has a side wall corresponding to the fixing plate 4122, so that the farthest end of the cam 44 from the rotation center pushes the corresponding side wall of the slider 4121 to compress the first elastic member 411. Therefore, the slider 4121 can be "C-shaped" or "L-shaped", and those skilled in the art can set it according to actual needs, and the present application does not limit this.

[0052] It can be understood that when the knocking piece 413 knocks the feed pipe 2, the first elastic piece 411 rebounds to the length in the free state; when the cam 44 pushes the sliding piece 4121 to slide in the direction away from the feed pipe 2, the first elastic piece 411 is compressed; thereby, when the first elastic piece 411 rebounds, all the stored potential energy is converted into the kinetic energy of the sliding piece 412, so as to drive the knocking piece 413 to knock the feed pipe 2.

[0053] refer to Figure 2 and Figure 4 The driving assembly 43 includes a first driving member 431 and a first rotating shaft 432; the first driving member 431 is installed in 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 is used to drive the first rotating shaft 432 to drive the cam 44 to rotate, so that the cam 44 is close to or away from the side of the sliding member 412 away from the knocking member 413 at the farthest end of the first rotating shaft 432.

[0054] In the embodiment of the present application, the first driving member 431 is installed in 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 is used to drive the first rotating shaft 432 to drive the cam 44 to rotate, so that the cam 44 is close to or away from the side of the sliding member 412 away from the knocking member 413 at the farthest end of the first rotating shaft 432. In this way, when the first driving member 431 drives the first rotating shaft 432 to drive the cam 44 to rotate, when the farthest end of the cam 44 from the first rotating shaft 432 is close to the side of the sliding member 412 away from the knocking member 413, the sliding member 412 is pushed to slide in the direction away from the feeding pipe 2, thereby pressing The first elastic member 411 is contracted to store elastic potential energy; when the farthest end of the cam 44 from the first rotating shaft 432 is away from the side of the sliding member 412 away from the knocking member 413, the first elastic member 411 rebounds and pushes the sliding member 412 to slide in the direction of the feeding pipe 2, and the elastic potential energy of the first elastic member 411 is converted into kinetic energy, driving the knocking member 413 to knock the feeding pipe 2, and so on and so forth, intermittently knocking the feeding pipe 2, so that the feeding pipe 2 is shaken by knocking, and the material blocked in the feeding pipe 2 is shaken off, so as to better discharge the material; the blockage of the feeding pipe 2 is avoided, and the material enters the mixing barrel 3 for mixing in time, thereby improving the mixing efficiency of the mixing device.

[0055] In a specific application, the output end of the first driving member 431 is connected to the first rotating shaft 432, and the end of the first rotating shaft 432 facing away from the first driving member 431 is connected to the cam 44, and the cam 44 is arranged between the sliding member 412 and the knocking member 413. Therefore, when the first driving member 431 is working, it drives the cam 44 to rotate so that the cam 44 is close to or away from the side of the sliding member 412 facing away from the knocking member 413 at the farthest end of the first rotating shaft 432. The first elastic member 411 stores energy or rebounds in this process, so that the knocking member 413 reciprocates between the base 42 and the feed pipe 2 under the joint action of the cam 44 and the first elastic member 411 to knock the feed pipe 2.

[0056] It is understandable that the first driving member 431 can be a motor, a cylinder or a hydraulic cylinder. Those skilled in the art can select one according to their needs, and this application does not impose any limitation on this.

[0057] refer to Figure 2 and Figure 5 In some embodiments of the present application, a dustproof component 5 is further included. A feeding port 11 is provided on the side of the feeding barrel 1 facing away from the feeding pipe 2. The dustproof component 5 is provided at the feeding port 11. The dustproof component 5 is rotatably connected to the feeding barrel 1. The dustproof component 5 can rotate relative to the feeding barrel 1 to cover or unblock the feeding port 11.

[0058] In the embodiment of the present application, a feeding port 11 is provided on the side of the feeding barrel 1 facing away from the conveying pipe 2, and a dustproof component 5 is provided at the feeding port. The dustproof component 5 is rotatably connected to the feeding barrel 1, thereby blocking or unblocking the feeding port 11 to prevent material dust in the feeding barrel 1 from escaping, posing a hazard to the operating personnel and causing pollution to the working environment.

[0059] In a specific application, since the material is generally in powder form, when the operator puts the material into the feeding barrel 1 from the feeding port 11, flying powder is easily generated, which is inhaled by the operator and affects the body. Therefore, a dustproof component 5 is provided at the feeding port 11, and the dustproof component 5 is rotatably connected to the feeding barrel 1. In this way, when the operator puts the material into the feeding barrel 1, the dustproof component 5 removes the covering of the feeding port 11; when the feeding is finished, the dustproof component 5 covers the feeding port 11 again to prevent the flying powder of the material from escaping.

[0060] refer to Figure 2 and Figure 5, in some embodiments of the present application, the dust-proof component 5 includes a second rotating shaft 51, a second elastic member 52, and a baffle 53. The second rotating shaft 51 is arranged 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 arranged 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 to block or unblock the feeding port 11.

[0061] In an embodiment of the present application, the second rotating shaft 51 is arranged 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 arranged 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. In this way, when an operator inputs materials from the feeding port 11, under the action of the gravity of the materials themselves, the baffle 53 releases the blockage of the feeding port 11, so that the materials can be input into the feeding cylinder 1. When the material input is completed, the second elastic member 52 rebounds, driving the baffle 53 to rotate back to its original position to block the feeding port 11.

[0062] 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, the second elastic member 52 is arranged 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 to block or unblock the feeding port 11.

[0063] 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, the second elastic member 52 is arranged 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.

[0064] Reference Figure 2 and Figure 5 , in some embodiments of the present application, the dust-proof component 5 further includes a partition 54. The partition 54 is arranged 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 a dust-proof component 5 is provided at each sub-feeding port 111.

[0065] In the embodiment of the present application, a partition plate 54 is further provided at the feeding port 11. The partition plate 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, and a dust-proof component 5 is provided at each sub-feeding port 111. Thus, when a single dust-proof component 5 is provided, the self-weight of the baffle 53 is too heavy, and a second elastic member 52 with a relatively high elastic coefficient is required. When there is less material left to be put in, the baffle 53 rebounds under the action of the second elastic member 52, resulting in the situation where the material cannot be completely put into the feeding cylinder 1.

[0066] In a specific application, the selection of the second elastic member 52 is related to the self-weight of the baffle 53 to ensure that the baffle 53 can rotate to block the feeding port 11 under the action of the second elastic member 52.

[0067] It can be understood that by providing the partition plate 54 at the feeding port 11 to divide the feeding port 11 into at least two sub-feeding ports 111, on the one hand, it is convenient to select the second elastic member 52 and the baffle 53, and on the other hand, it is more convenient for the material to be put into the feeding cylinder 1 through at least two sub-feeding ports 111.

[0068] Reference Figure 3 and Figure 5 In some embodiments of the present application, the dust-proof component 5 further includes a material blocking member 55. One end of the material blocking member 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 feeding pipe 2 to block the gap between the second rotating shaft 51 and the inner wall of the feeding cylinder 1.

[0069] In the embodiment of the present application, since the second rotating shaft 51 is connected to the feeding cylinder 1, along the direction perpendicular to the axis of the second rotating shaft 51, a gap will inevitably be formed between the second rotating shaft 51 and the feeding cylinder 1. One end of the material blocking member 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 feeding 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 through this gap, improving the operation safety of the operator.

[0070] It can be understood that the material blocking member 55 can be integrally formed with the feeding cylinder 1, or can be bonded, screwed, or clamped to the side wall of the feeding cylinder 1. Those skilled in the art can make a choice according to requirements, and the present application does not limit this.

[0071] In a specific application, an arc surface adapted to the surface of the second rotating shaft 51 is provided at one end of the material blocking member 55 facing the second rotating shaft 51, thereby further improving the blocking of the gap between the second rotating shaft 51 and the inner wall of the feeding cylinder 1.

[0072] Reference Figure 6In some embodiments of the present application, the mixing device also includes a second driving member 61, a third rotating shaft 62 and a stirring member 63. A mixing chamber 31 is provided in the mixing barrel 3. The second driving member 61 is installed on the mixing barrel 3. The third rotating shaft 62 is connected to the second driving member 61. The third rotating shaft 62 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.

[0073] In the embodiment of the present application, a mixing chamber 31 is provided in the mixing barrel 3, the second driving member 61 is installed on the mixing barrel 3, the third rotating shaft 62 is connected to the second driving member 61, the third rotating shaft 62 extends into the mixing chamber 31, the 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 to complete the mixing of the input material.

[0074] In a specific application, a discharge port is further provided on the side of the mixing barrel 3 facing away from the feeding pipe 2, and the material after mixing is completed flows out from the discharge port.

[0075] refer to Figure 6 In some embodiments of the present application, the mixing device also 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 arranged on the third rotating shaft 62 at intervals, 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, and 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.

[0076] In the embodiment of the present application, at least two connecting members 71 are arranged on the third rotating shaft 62 at intervals along the axial direction of 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. Therefore, 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, and at the same time, drives the scraper 72 to scrape off the material attached to the inner wall of the mixing chamber 31. On the one hand, all the materials can be fully mixed, and on the other hand, the materials are prevented from adhering to the inner wall of the mixing chamber 31 to affect the subsequent use of the mixing device.

[0077] It can be understood that at least two connecting members 71 are arranged at intervals on the third rotating shaft 62, one end of each connecting member 71 is connected to the third rotating shaft 62, and the other end is connected to the scraper 72. In the vertical direction, the two ends of a scraper 72 are respectively connected to a connecting member 71, so that the scraper 72 can stably scrape the material attached to the inner wall of the mixing chamber 31.

[0078] Reference Figure 6 In some embodiments of the present application, an arc surface is provided on one side of the scraping plate 72 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.

[0079] In an embodiment of the present application, an arc surface is provided on one side of the scraping plate 72 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, thereby reducing the friction between the scraping plate 72 and the inner wall of the mixing chamber 31 and improving the efficiency of scraping off the attached materials.

[0080] It can be understood that an arc surface is provided on one side of the scraping plate 72 facing the inner wall of the mixing chamber 31, so that a line contact is formed between the scraping plate 72 and the mixing chamber 31, thereby reducing the friction between the scraping plate 72 and the mixing chamber 31.
