[0028] The embodiments of the present disclosure are described below in detail. Examples of the embodiments are shown in the drawings. The same or similar numerals represent the same or similar elements or elements having the same or similar functions throughout the specification. The embodiments described below with reference to the accompanying drawings are exemplary. These embodiments are only used to explain the present disclosure, and should not be construed as a limitation to the present disclosure.
[0029] The present disclosure relates to an automatic powder sampling device, including a stock bin 100, a sampling assembly, a protective cover 200, and a drive assembly.
[0030] As shown in FIG. 1 to FIG. 7, an installing position is provided on a lower part of an outer side wall of the stock bin 100, and the lower part here does not include a bottom surface of the stock bin 100, rather a part of the outer side wall of the stock bin 100 that extends in a vertical direction. As shown in FIG. 1, the protective cover 200 passes through the installing position and is installed to the lower part of the outer side wall of the stock bin 100. A discharge port 210 for discharging a material is formed at a bottom of the protective cover 200. The protective cover 200 is configured to protect a material from external contamination during a sampling process. As shown in FIG. 2 to FIG. 6, the sampling assembly includes a scraping rod 300, a push unit, a sampling wheel 320, and a cam 330. As shown in FIG. 5, the sampling wheel 320 has a cylindrical structure, an end surface of the sampling wheel 320 is provided with a belt pulley 430, and the belt pulley 430 and the sampling wheel 320 are arranged on the same central axis. An outer side wall of the sampling wheel 320 abuts against or is close to an inner side wall of the protective cover 200, thereby reducing contact of a material on the sampling wheel 320 with the outside world. A groove 322 is formed on the outer side wall of the sampling wheel 320 to hold a material scraped by the scraping rod 300. The groove 322 may be provided with two second through holes 323, and the scraping rod 300 and the push unit are arranged in the sampling wheel 320 through the respective second through holes 323. A first installing hole 321 extending along a thickness direction of the sampling wheel 320 is provided at a center of the sampling wheel 320, and the first installing hole 321 is facilitate to sleeve the sampling wheel 320 on the cam 330, such that the sampling wheel 320 can be arranged in the protective cover 200. As shown in FIG. 4, the push unit includes a push rod 312 and a push plate 311 which arc integrally formed. The push plate 311 is shaped to match the groove 322 and arranged in the groove 322. The push plate 311 is provide with a first through hole which is sized to match a rod body of the scraping rod 300, and the scraping rod 300 passes through the first through hole and is slidable relative to the push plate 311. As shown in FIG. 7, the push rod 312 and the scraping rod 300 each are provided with a sliding portion 350 and a spring 340 which is arranged above the sliding portion 350. The spring 340 is used for elastic reset of the push rod 312 or the scraping rod 300 after extending out of the sampling wheel 320. As shown in FIG. 6 and FIG. 7, the cam 330 includes a first running portion and a second running portion which are fixedly connected. The cam 330 and the sampling wheel 320 are arranged on the same central axis. The scraping rod 300 and the push rod 312 could slide relative to surfaces of the first running portion and the second running portion, respectively, such that the scraping rod 300 and the push rod 312 cooperate with each other under the drive of the sampling wheel 320 to complete scraping and pushing procedures. Therefore, the automatic sampling device of the present disclosure has the characteristics of automatic sampling, high sampling efficiency, simple structure, and reduced material contamination during sampling, and is convenient for promotion in the field of automatic sampling during production of cathode and anode materials for lithium batteries.
[0031] In some embodiments of the present disclosure, as shown in FIG. 6 and FIG. 7, the cam 330 includes a first running portion and a second running portion which are fixedly connected. As shown in FIG. 6 and FIG. 7, the first running portion includes a first convex surface 3311, a first side surface 3313, and concave surfaces 3312. The first running portion has a cylindrical structure, and the first side surface 3313 is an outer side surface of the first running portion. The first side surface 3313 is in a shape of a semi-cylindrical outer side surface and accounts for a half of the outer side wall of the first running portion. The remaining part of the outer side wall of the first running portion includes a first convex surface 3311 formed due to a middle projection and two concave surfaces 3312 at two sides of the first convex surface 3311. After completing scraping, the scraping rod 300 slides on any concave surface 3312 to buffer vibration caused by reset of the spring 340. The second running portion includes a second convex surface 3321 formed due to a middle bulge and two inclined surfaces 3322 at two sides of the second convex surface 3321. When the push rod 312 slides along one inclined surface 3322 to the second convex surface 3321 with the rotation of the sampling wheel 320, the push rod 312 pushes the material in the groove 322 to a weighing unit 500. The inclined surfaces 3322 are used to buffer an elastic force produced due to the reset of the push rod 312 by the spring 340. Specifically, the first convex surface 3311 and the second convex surface 3321 are arranged at a same side of the cam 330, and both face towards the discharge port 210.
[0032] In a further embodiment of the present disclosure, as shown in FIG. 2, FIG. 3, and FIG. 7, the cam 330 is fixed to the sampling wheel 320, and the scraping rod 300 and the push rod 312 slide on the surfaces of the first running portion and the second running portion under the rotation of the sampling wheel 320, respectively. The second running portion further includes a second side surface, and the second side surface is in a shape of a semi-cylindrical outer side surface. When the scraping rod 300 rotates with the sampling wheel 320 to the first side surface 3313, the scraping rod 300 extends out of the sampling wheel 320 and rotates with the sampling wheel 320, and meanwhile, a material in the stock bin 100 is scraped to the outer side wall of the sampling wheel 320. When the scraping rod 300 rotates with the sampling wheel 320 to one concave surface 3312, the spring 340 undergoes elastic reset to make the scraping rod 300 return to the miginal position. When the scraping rod 300 rotates with the sampling wheel 320 to the first convex surface 3311, the scraping rod 300 is located at a lower position than the push rod 312 due to a height difference between the first convex surface 3311 and the second convex surface 3321, that is, the push rod 312 slides to the second convex surface 3321 and pushes the material to the weighing unit 500. When the push rod 312 rotates with the sampling wheel 320 to the second side surface, the push rod 312 remains stationary and a groove 322 for holding a material is formed by the push plate 311 and the outer side wall of the sampling wheel 320. When the push rod 312 rotates with the sampling wheel 320 to one inclined surface 3322, the spring 340 undergoes elastic reset to make the push rod 312 return to the original position.
[0033] In some embodiments of the present disclosure, as shown in FIG. 4 and FIG. 5, at least two grooves 322 may be formed in the sampling wheel 320, and two second through holes 323 are formed in each groove 322 Each second through hole 323 comprises an upper half section of the second through hole 323 and a lower half section of the second through hole 323. The upper half section of the second through hole 323 is sized to match with an upper half section of the scraping rod 300 or the push rod 312, and the lower half section of the second through hole 323 is sized to match with the sliding portion 350. When the scraping rod 300 or the push rod 312 extends out of the sampling wheel 320, the spring 340 is contracted by the sliding portion 350. When the scraping rod 300 or the push rod 312 completes scraping or pushing, that is, the scraping rod 300 or the push rod 312 rotates with the sampling wheel 320 to one concave surface 3312 or one inclined surface 3322 of the cam 330, the spring 340 provides an elastic force to reset the scraping rod 300 or the push rod 312. A plurality of grooves 322 are arranged at equal intervals on the outer side wall of the sampling wheel 320, and each groove 322 is provided with a scraping rod 300 and a push rod 312, such that the sampling wheel 320 can achieve sampling and pushing synchronously, thereby improving the sampling efficiency. It should be noted that a number of the grooves 322 is determined according to a size of the sampling wheel 320.
[0034] In other embodiments of the present disclosure, as shown in FIG. 1, the automatic powder sampling device further includes a weighing unit 500. A first bracket is welded to a bottom of the stock bin 100, which is an installing plate is shaped to match with a bottom surface of the stock bin 100. An end of the first bracket extends outwards to form a support portion which is welded with a second bracket and a third bracket. The second bracket is a bracket for a motor 400, and the third bracket has a chair-like structure. The second bracket and the third bracket are provided to support the drive assembly and the weighing unit 500, respectively, thereby improving the structural stability of the drive assembly when operating and the weighing unit 500 when weighing. As shown in FIG. 1, the drive assembly includes a motor 400, a driving wheel 410, a belt 420, and a belt pulley 430. The motor 400 is provided with a rotating shaft 401, by means of which the driving wheel 410 is rotatably connected to the motor 400. The belt pulley 430 rotates with the driving wheel 410 through the belt 420. The motor 400 drives the driving wheel 410 to rotate and thus drives the belt pulley 430 to rotate through the belt 420, such that the sampling wheel 320 rotates with the belt pulley 430. In the present disclosure, the belt 420 and the belt pulley 430 are in transmission connection to reduce a vibration generated when the drive assembly or the sampling wheel 320 rotates, thereby improving a weight accuracy of a sampled material.
[0035] In some embodiments of the present disclosure, as shown in FIG. 1, FIG. 2, and FIG. 3, the protective cover 200 is shaped and configurated to match with the sampling wheel 320, and the protective cover 200 may be a volute-like hollow housing. A side of the protective cover 200 away from the outer side wall of the stock bin 100 extends downwards to form a discharge port 210, and the discharge port 210 faces towards the weighing unit 500 or is arranged above the weighing unit 500. The protective cover 200 and the stock bin 100 are integrally formed, the protective cover 200 communicates with the stock bin 100, and a second installing hole is formed in a center of the protective cover 200. The sampling wheel 320 is rotatably arranged on the outer side wall of the protective cover 200 through the second installing hole. The outer side wall of the sampling wheel 320 abuts against or is close to an inner wall of the protective cover 200, such that the belt pulley 430 is arranged outside the protective cover 200, which is convenient for the connection between the belt pulley 430 and the drive assembly. The protective cover 200 is used to reduce the external contamination to a material sampled by the sampling assembly. Specifically, an end of the protective cover 200 towards the stock bin 100 is provided with an open feed port, such that, when the sampling wheel 320 rotates to the feed port, the scraping rod 300 extends out of the sampling wheel 320 and scrapes a material to the groove 322.
[0036] With the sampling of the sampling assembly as an example, an operator sets a sampling time and a sampling period, and when running, the motor 400 drives the sampling assembly to operate through the belt 420. ln the stock bin 100, the scraping rod 300 slides relative to the surface of the center cam 330 to extend out of the sampling wheel 320 for scraping such that a material falls on the outer side wall of the sampling wheel 320 with the sliding of the scraping rod 300. The sampling wheel 320 continues to rotate, and then the scraping rod 300 is reset under the drive of the concave surface 3312 of the cam 330 and the spring 340. When the material on the sampling wheel 320 is transferred out of the stock bin 100 and the sampling wheel 320 rotates to a position above the discharge port 210, the bottom of the push rod 312 slides to the second running portion of the cam 330, such that the push rod 312 pushes the material in the groove 322 to the protective cover 200 and the material slides along the inner wall of the protective cover 200 onto the weighing unit 500. The sampling device continuously rotates in a clockwise or counterclockwise direction for sampling and stops working when a set sampling amount is achieved, and a resulting sample is then manually packed into a packing bag.
[0037] In the description of the specification, reference to the terms such as "some examples" means that a specific feature, structure, material, or characteristic described in combination with the embodiment(s) or example(s) are included in at least one embodiment or example of the present disclosure. In this specification, the schematic representations of the above-mentioned terms do not necessarily refer to the same embodiment or example. Moreover, the described specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.
[0038] Although the embodiments of the present disclosure have been illustrated, it should be understood that those of ordinary skill in the art may still make various changes, modifications, replacements, and variations to the above embodiments without departing from the principle and spirit of the present disclosure, and the scope of the present disclosure is limited by the claims and legal equivalents thereof.
