[0037] Please see Figures 1 to 7 To better understand the battery powder feeding device 10 of this application, the following further explanation of the battery powder feeding device 10 is provided:

[0038] One embodiment of the battery powder feeding device 10 includes a hopper 100, a feeding mechanism 200, and a discharging mechanism 300. The hopper 100 is mounted on a frame 400 and has an inner cavity 101 for buffering materials. The feeding mechanism 200 includes a feeding drive 210 and a feeding screw 220. The feeding drive 210 is fixedly mounted on the hopper 100, and one end of the feeding screw 220 is fixedly connected to the power output end of the feeding drive 210, passing through the inner cavity 101. The discharging mechanism 300 includes a distributor 310, a distributor opening and closing plate 320, a distributor frame 330, and a distributor drive. The moving part 340; the material feeder 310 has a material feeding chamber 3101 and a material discharge port 3102. The material discharge port 3102 and the inner cavity 101 of the hopper are both connected to the material feeding chamber 3101. The material feeding opening and closing plate 320 and the material feeding frame 330 are both located below the material feeder 310. The material feeding opening and closing plate 320 has a material passage port 3201. The material feeding drive 340 is installed on the frame 400. The material feeding drive 340 is used to drive the material feeding opening and closing plate 320 to slide relative to the material feeding frame 330, so as to adjust the relative opening and closing degree of the material discharge port 3102 and the material passage port 3201.

[0039] In this embodiment, the feeding screw 220 is driven to rotate by the feeding drive 210 to efficiently transport the material buffered in the inner cavity 101 of the hopper to the material distribution cavity 3101. Then, the material distribution drive 340 drives the material distribution opening and closing plate to slide relative to the material distribution frame 330, thereby adjusting the relative opening and closing degree of the discharge port 3102 and the passage port 3201. This allows the battery powder feeding device 10 to effectively control the flow rate and velocity of materials with different flowability passing through the discharge port 3102 and the passage port 3201 in sequence by adjusting the relative opening and closing degree of the discharge port 3102 and the passage port 3201. As a result, the battery powder feeding device 10 can better adapt to the high-precision material loading requirements.

[0040] It should be noted that the relative opening and closing degree of the discharge port 3102 and the passage port 3201 is the overlapping area of ​​the projection of the discharge port 3102 and the passage port 3201 on the same horizontal plane, so that the size of the discharge channel formed when the material passes through the discharge port 3102 and the passage port 3201 from top to bottom at the same time.

[0041] It should be noted that in this embodiment, the fabric frame 330 is a hollow structure, so the material will pass through the feeding port 3102, the material passage port 3201 and the fabric frame 330 in sequence during the feeding process, that is, it will finally be filled into the square casket 700 through the inner frame of the fabric frame 330.

[0042] like Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment, the feeding mechanism 300 further includes a rotating scraper 350, which is located in the material feeding cavity 3101. The rotating scraper 350 is sleeved on the feeding screw 220 and is used to scrape the material into the feeding port 3102.

[0043] It is understandable that by adding a rotating scraper 350 inside the fabric cavity 3101 and connecting the rotating scraper 350 to the feeding screw 220, the feeding screw 220 can drive the rotating scraper 350 to rotate synchronously. This effectively improves the flowability of the material through the rotation of the rotating scraper 350, allowing the material in the fabric cavity 3101 to be smoothly scraped into the discharge port 3102, thereby effectively reducing the risk of material blockage at the discharge port 3102.

[0044] like Figure 1 , Figure 2 and Figure 6 As shown, in one embodiment, the rotating scraper 350 includes a rotating body 3510 and a plurality of scraper blades 3520; the plurality of scraper blades 3520 are arranged at intervals around the periphery of the rotating body 3510, and the rotating body 3510 is fixedly connected to the other end of the feeding screw 220.

[0045] It is understandable that, since the rotating body 3510 is fixedly connected to the other end of the feeding screw 220, the feeding drive 210 can synchronously drive the feeding screw 220 and the rotating body 3510 to rotate, thereby improving the utilization rate of the power output of the feeding drive 210. This allows the rotating body 3510 to drive multiple scraper blades 3520 to rotate around the rotating body 3510, effectively improving the flowability of the material in the cloth cavity 3101. This ensures that the material in the cloth cavity 3101 is smoothly scraped into the discharge port 3102, thereby effectively reducing the risk of material blockage in the discharge port 3102 and effectively preventing the material in the cloth cavity 3101 from agglomerating. Specifically, in this embodiment, the rotating body 3510 and the other end of the feeding screw 220 are fixedly connected by a threaded connection, improving the ease of assembly of the rotating scraper 350. The helical direction of the threaded connection between the rotating body 3510 and the other end of the feeding screw 220 is opposite to the rotation direction of the feeding screw 220 to prevent the rotating body 3510 from loosening and falling off. In other embodiments, the rotating body 3510 and the other end of the feeding screw 220 are fixedly connected by a snap-fit ​​connection. Of course, this is not a limitation, and those skilled in the art can make other choices as needed.

[0046] It should be noted that the feeding drive unit 210 is a three-phase drive motor, which can provide greater torque, enabling the feeding screw 220 to adapt to the conveying of materials with different flow rates.

[0047] like Figure 1 and Figure 2 As shown, in one embodiment, the hopper 100 is further provided with a feed inlet 102 and an overflow outlet 103; both the feed inlet 102 and the overflow outlet 103 are connected to the inner cavity 101 of the hopper, and the inner cavity 101 of the hopper is connected to the material distribution cavity 3101 through the overflow outlet 103.

[0048] It is understood that in this embodiment, the feed inlet 102 is located at the top of the hopper 100. The material to be sintered at high temperature is pre-buried in the inner cavity 101 of the hopper through the feed inlet 102, so that the feeding screw 220 can efficiently transport the material from the inner cavity 101 of the hopper to the material distribution cavity 3101 through the overflow port 103. Since the hopper 100 gradually narrows from the inner cavity 101 to the overflow port 103, the material gradually concentrates towards the overflow port 103 under its own weight and the rotation of the feeding screw 220, thereby improving the material conveying efficiency.

[0049] Furthermore, the feed inlet 102 is equipped with a flow control device, which enables precise control of the flow rate and velocity of the material buffer.

[0050] like Figures 1 to 5As shown, in one embodiment, the feeder 310 includes a feed upper shell 3110 and a feed base 3120; the feed upper shell 3110 is connected to the bottom of the hopper 100, the feed upper shell 3110 and the feed base 3120 together form a feed cavity 3101, and the discharge port 3102 is opened in the feed base 3120.

[0051] It is understood that the fabric cavity 3101 is assembled and enclosed by the fabric upper shell cover 3110 and the fabric base 3120. Therefore, the relative opening and closing degree of the feed port 3102 and the feed port 3201 is minimized. That is, when the feed channel formed by the feed port 3102 and the feed port 3201 is closed by adjusting the feed port 3102 and the feed port 3201, the material can be restricted through the sealed fabric cavity 3101, effectively preventing the material from seeping out.

[0052] Specifically, in this embodiment, the fabric base 3120 has multiple discharge ports 3102, which are arranged in an array. The shape of the aggregate discharge port 3103 formed by the multiple discharge ports 3102 matches the shape of the loading port of the square sagger 700. This ensures that the material passing through the discharge ports 3102, the feed port 3201, and the fabric frame 330 is filled into the square sagger 700 with good uniformity, thereby greatly reducing the angle of repose of the material after loading, making the material in the square sagger 700 more compact and flat, and thus improving the space utilization of the square sagger 700.

[0053] like Figures 2 to 7 As shown, in one embodiment, the fabric frame 330 is fixedly connected to the fabric chassis 3120; the power output end of the fabric drive component 340 is connected to the fabric opening and closing plate 320 through a gear and rack transmission mechanism to drive the fabric opening and closing plate 320 to reciprocate relative to the fabric frame 330. This effectively ensures the stability and reliability of the reciprocating sliding of the fabric opening and closing plate 320 relative to the fabric frame 330.

[0054] Specifically, in this embodiment, the fabric opening and closing plate 320 has multiple material passages 3201, which are linearly distributed. By driving the fabric opening and closing plate 320 to slide relative to the fabric frame 330, the relative opening and closing degree of the multiple discharge ports 3102 and the multiple material passages 3201 can be adjusted simultaneously, thereby improving the uniformity of material discharge. In other embodiments, the fabric frame 330 is fixedly connected to the crossbeam structure of the frame 400.

[0055] It should be noted that in this embodiment, the fabric driving component 340 is a drive motor. The rotating shaft of the drive motor is connected to a transmission rod via a coupling. The gear on the transmission rod meshes with the rack on the fabric opening and closing plate 320, effectively ensuring the reliability and stability of the fabric driving component 340 driving the fabric opening and closing plate 320 to reciprocate relative to the fabric frame 330. In other embodiments, the power output end of the fabric driving component 340 is connected to the fabric opening and closing plate 320 via a double gear meshing transmission mechanism; in another embodiment, the power output end of the fabric driving component 340 is connected to the fabric opening and closing plate 320 via a double rack meshing transmission mechanism. Of course, this is not a limitation, and those skilled in the art can make other choices as needed. For example, the fabric driving component 340 is a drive cylinder, and the telescopic shaft of the drive cylinder is fixedly connected to the fabric opening and closing plate 320, driving the fabric opening and closing plate 320 to slide relative to the fabric frame 330.

[0056] like Figures 4 to 7 As shown, in one embodiment, the fabric opening and closing plate 320 slides relative to the fabric frame 330 along a first preset direction, so that the relative opening and closing degree between the feed port 3102 and the feed port 3201 changes from large to small; the fabric opening and closing plate 320 slides relative to the fabric frame 330 along a second preset direction, so that the relative opening and closing degree between the feed port 3102 and the feed port 3201 changes from small to large, and the first preset direction is opposite to the second preset direction.

[0057] It is understandable that by adjusting the relative opening and closing degree of the feeding port 3102 and the passing port 3201, the battery powder feeding device 10 can adopt a larger relative opening and closing degree in the early stage of material filling to accelerate the feeding; and adopt a smaller relative opening and closing degree in the later stage of material filling to achieve slow and high-precision feeding control.

[0058] It should be noted that, as Figure 6 As shown, the first preset direction is the direction indicated by the X arrow; conversely, the second preset direction is the direction indicated by the Y arrow.

[0059] Specifically, in this embodiment, each discharge port 3102 is an isosceles triangle, and the perpendicular bisector of each discharge port 3102 is parallel to the direction in which the fabric opening and closing plate 320 slides back and forth relative to the fabric frame 330. In one embodiment, each feed port 3201 is rectangular. Since the discharge port 3102 is an isosceles triangle, and the perpendicular bisector of the discharge port 3102 is parallel to the direction in which the fabric opening and closing plate 320 slides back and forth relative to the fabric frame 330, the relative opening and closing degree of the isosceles triangular discharge port 3102 and the rectangular feed port 3201 can be controlled to effectively control the flow rate and velocity through the discharge port 3102, the feed port 3201, and the inner frame of the fabric frame 330. Of course, this is not a limitation, and those skilled in the art can make other choices as needed. For example, the shape of the discharge port 3102 can be rectangular or semi-circular.

[0060] More specifically, such as Figure 7 (a) As shown in the diagram, when the projection of the isosceles triangle discharge port 3102 completely falls into the projection of the rectangular feed port 3201, the battery powder feeding device 10 is in a rapid feeding state; as shown in the diagram. Figure 7 As shown in states (b) and (c), when the projected portion of the isosceles triangular discharge port 3102 falls into the projected portion of the rectangular feed port 3201, the battery powder feeding device 10 is in a speed-adjusting feeding state; Figure 7 As shown in state (d), when the projection of the isosceles triangle discharge port 3102 does not fall into the projection of the rectangular feed port 3201, the battery powder feeding device 10 is in a stopped feeding state. Thus, especially for materials with good flowability, the battery powder feeding device 10 can achieve multi-stage speed control of feeding to effectively meet the high-precision material loading requirements, thereby improving the accuracy of material loading.

[0061] like Figure 3 and Figure 5As shown, in one embodiment, a first guide slider 3310 is provided on one side of the fabric frame 330, and a second guide slider 3320 is provided on the other side of the fabric frame 330. The two sides of the fabric opening and closing plate 320 slide against the first guide slider 3310 and the second guide slider 3320 respectively. The sliding direction of the first guide slider 3310 relative to the second guide slider 3320 is parallel to a first preset direction. This effectively improves the smoothness of the reciprocating sliding of the fabric opening and closing plate 320 relative to the fabric frame 330, allowing the fabric opening and closing plate 320 to more accurately control the relative opening and closing degree of the feed port 3102 and the feed port 3201 under the drive of the fabric driving member 340. Of course, this is not a limitation, and those skilled in the art can make other choices as needed. For example, the fabric opening and closing plate 320 and the fabric frame 330 can be slidably connected using a slider and a groove sliding method.

[0062] like Figure 4 As shown, in one embodiment, the first guide slider 3310 includes a plurality of first guide pulleys, which are linearly distributed and rotatably connected to the fabric frame 330; the second guide slider 3320 includes a plurality of second guide pulleys, which are linearly distributed and rotatably connected to the fabric frame 330. This effectively improves the smoothness of the reciprocating sliding of the fabric opening / closing plate 320 relative to the fabric frame 330, allowing the fabric opening / closing plate 320, driven by the fabric drive member 340, to more precisely control the relative opening and closing degree of the feed port 3102 and the feed inlet 3201.

[0063] Please refer to the following: Figures 1 to 8 This application also provides a battery powder feeding device, including a frame 400, a crucible conveyor line 500, a weighing module 600, and a battery powder feeding device 10 of any of the above embodiments. The crucible conveyor line 500 is used to transport square crucibles 700 to directly below the cloth frame 330. A crossbeam steel structure 510 is installed below the crucible conveyor line 500, and the crossbeam steel structure 510 is fixedly connected to the frame 400. The weighing module 600 is fixedly installed on the crossbeam steel structure 510 and aligned with the cloth frame 330. The weighing module 600 is used to weigh the weight of the square crucibles 700. The weighing module 600 is electrically connected to the control terminal of the feeding drive unit 210 and the control terminal of the cloth drive unit 340, respectively.

[0064] In this embodiment, the square crucible 700 is easily transported to the area directly below the fabric frame 330 via the crucible conveyor line 500, so that the loading port of the square crucible 700 is aligned with the combined unloading port 3103 composed of multiple unloading ports 3102. This helps to improve the automation level of the transportation of the square crucible 700.

[0065] Furthermore, when the square crucible 700 is conveyed by the crucible conveyor line 500 to the area directly below the fabric frame 330, the square crucible 700 falls into the weighing area of ​​the weighing module 600. The weighing end of the weighing module 600 abuts upward to lift the square crucible 700, causing it to leave the transport horizontal line of the crucible conveyor line 500, thereby performing a weighing operation on the square crucible 700. In this way, the weighing module 600 can transmit the weight information of the square crucible 700 to the feeding drive 210 and the fabric drive 340 in a timely manner via electrical signals to control the output power of the feeding drive 210 and the fabric drive 340.

[0066] Furthermore, a lifting cylinder is installed below the weighing module 600 to drive the weighing module 600 to move up and down; the sagger conveyor line 500 has a weighing cavity, and the weighing end of the weighing module 600 extends to the weighing cavity. In this way, by driving the weighing module 600 to rise through the lifting cylinder, the weighing end of the weighing module 600 can come into contact with the bottom of the square sagger 700.

[0067] like Figure 1 and Figure 8 As shown, in one embodiment, the battery powder feeding device 10 further includes a dust collection hopper 800, which is installed below the crucible conveyor line 500. The upper end of the dust collection hopper 800 is provided with a conical collection port 801, which is correspondingly arranged below the crucible conveyor line 500. The lower end of the dust collection hopper 800 is provided with a collection bin 802, and the conical collection port 801 is connected to the collection inner cavity of the collection bin 802. The collection inner cavity of the collection bin 802 is used to collect materials.

[0068] It is understandable that the cone-shaped material collection port 801 covers the bottom of the crucible conveyor line 500, and the dust collection hopper 800 can collect and utilize materials that are accidentally spilled during the filling process, effectively avoiding material waste and reducing pollution to the workshop environment.

[0069] The working principle of the battery powder feeding equipment is as follows: First, the square crucible 700 containing the material to be filled is automatically transported to the area directly below the material feeding frame 330 via the crucible conveyor line 500. The weighing end of the weighing module 600 weighs and records the weight of the square crucible 700 containing the material to be filled. Second, the weighing module 600 simultaneously transmits electrical signals to the feeding drive 210 and the material feeding drive 340. The feeding drive 210 is activated to drive the feeding screw 220 and the rotating body 3510 to rotate. The material feeding drive 340 is activated to drive the material feeding opening and closing plate 320 to slide relative to the material feeding frame 330, thereby adjusting the discharge port 3102 and the feed opening and closing plate 320. The relative opening and closing degree of the feed inlet 3201 is adjusted to perform the feeding operation; then, the weighing module 600 records the weight of the square sagger 700 in real time. The weighing module 600 synchronously controls the output power of the cloth-laying drive 340 through an electrical signal to continue adjusting the relative opening and closing degree of the feed inlet 3102 and the feed outlet 3201 until the material filling operation is completed; finally, the feeding drive 210 and the cloth-laying drive 340 stop working, and the weighing end of the weighing module 600 stops weighing the square sagger 700. At this time, the square sagger 700 falls back onto the sagger conveyor line 500 and is automatically transported to the next processing step.

[0070] It should be noted that the battery powder feeding device 10 disclosed herein only protects the telecommunication connection between each component and the weighing module 600, while the control method of the weighing module 600 belongs to the prior art and is not within the protection scope of this disclosure.

[0071] Compared with the prior art, the present invention has the following advantages, including but not limited to:

[0072] 1. The feeding screw 220 is driven to rotate by the feeding drive component 210 to efficiently transport the material buffered in the inner cavity 101 of the hopper to the material distribution cavity 3101. Then, the material distribution drive component 340 drives the material distribution opening and closing plate to slide relative to the material distribution frame 330, thereby adjusting the relative opening and closing degree of the discharge port 3102 and the passage port 3201. This allows the battery powder feeding device 10 to effectively control the flow rate and velocity of materials with different flowability passing through the discharge port 3102 and the passage port 3201 in sequence by adjusting the relative opening and closing degree of the discharge port 3102 and the passage port 3201. As a result, the battery powder feeding device 10 can better adapt to the high-precision material loading requirements.

[0073] 2. By adding a rotating scraper 350 inside the fabric cavity 3101 and connecting the rotating scraper 350 to the feeding screw 220, the rotating screw 220 can drive the rotating scraper 350 to rotate synchronously. This effectively improves the flowability of the material through the rotation of the rotating scraper 350, allowing the material in the fabric cavity 3101 to be smoothly scraped into the discharge port 3102, thereby effectively reducing the risk of material blockage at the discharge port 3102.

[0074] 3. The feed inlet 102 is located at the top of the hopper 100. The material to be sintered at high temperature is pre-buried in the inner cavity 101 of the hopper through the feed inlet 102, so that the feeding screw 220 can efficiently transport the material from the inner cavity 101 of the hopper to the material distribution cavity 3101 through the overflow port 103. In particular, since the hopper 100 has a gradually narrowing shape from the inner cavity 101 to the overflow port 103, the material gradually concentrates towards the overflow port 103 under its own weight and the rotation of the feeding screw 220, thereby improving the material conveying efficiency.

[0075] 4. The shape of the combined feeding port 3103, composed of multiple feeding ports 3102, matches the shape of the loading port of the square sagger 700. This ensures better uniformity of material filling into the square sagger 700 through the feeding port 3102, the material passage port 3201, and the material distribution frame 330, thereby greatly reducing the angle of repose of the material after loading, making the material in the square sagger 700 more compact and flat, and thus improving the space utilization rate of the square sagger 700.

[0076] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
