Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a feeding device for agglomerated powder and its vibrating feeding mechanism. Background Technology

[0002] In the dry electrode film-forming composite machine, the tendency of the film powder to agglomerate during the film-forming process can easily lead to localized material accumulation during the roller pressing stage. This affects the uniformity of film thickness and areal density, resulting in poor film quality and easy breakage. In existing technologies, to avoid powder agglomeration affecting film quality, the powder is typically manually sieved before being added to a hopper. The powder in the hopper is then conveyed by a conveyor belt to the rollers for pressing. This manual sieving and feeding method requires small, multiple feedings, significantly increasing labor costs and failing to overcome powder agglomeration during the conveying process. Utility Model Content

[0003] In view of this, the present invention provides a vibrating feeding mechanism, which reduces the labor intensity of workers, reduces labor costs, has high efficiency in powder screening, provides powder with better uniformity for film formation, and improves the quality of the film.

[0004] This utility model also provides a feeding device for agglomerated powder.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vibrating feeding mechanism includes a receiving mechanism, a grading and screening mechanism, and a vibrating conveying mechanism arranged sequentially along the conveying direction. The grading and screening mechanism conveys the material transported by the receiving mechanism to the vibrating conveying mechanism. The grading and screening mechanism includes a plurality of screening devices stacked at intervals along the height direction. Each layer of screening devices is connected to a first vibrator that drives its vibration. Each screening device includes a screen, and in adjacent screening devices, the mesh size of the screen of the upper screening device is smaller than that of the screen of the lower screening device.

[0007] As can be seen from the above technical solution, the vibration feeding mechanism provided by this utility model replaces the manual screening method used in the prior art by setting up a grading screening mechanism. It eliminates the need for small-batch, multiple feedings, reducing the labor intensity and labor costs of workers. Through step-by-step screening, the agglomerated powder is gradually screened into particles, resulting in high powder screening efficiency and more uniform powder size. This provides powder with better uniformity for film formation and improves the quality of the film.

[0008] This utility model also provides a feeding device for agglomerated powder, including a vibrating feeding mechanism. The discharge position of the vibrating feeding mechanism is correspondingly set to the feed position of the film-forming roller. The vibrating feeding mechanism is the aforementioned vibrating feeding mechanism.

[0009] The agglomerated powder feeding device of this utility model includes the above-mentioned vibrating feeding mechanism, and therefore has the advantages of the above-mentioned vibrating feeding mechanism, which will not be described in detail here. Attached Figure Description

[0041] This utility model discloses a vibrating feeding mechanism, which reduces the labor intensity of workers, lowers labor costs, has high efficiency in powder screening, provides more uniform powder for film formation, and improves the quality of the film.

[0042] This utility model also discloses a feeding device for agglomerated powder.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] See Figures 1 to 2 The vibrating feeding mechanism of this utility model includes a receiving mechanism 1, a grading and screening mechanism 2, and a vibrating conveying mechanism 3, which are sequentially connected along the conveying direction. The receiving mechanism 1 is used to receive the added powder, and the grading and screening mechanism 2 is used to grade and screen the powder flowing out of the receiving mechanism 1 to prevent the powder from agglomerating during the transmission process. This ensures that the powder flowing to the vibrating conveying mechanism 3 is in a loose, non-agglomerated state. The vibrating conveying mechanism 3 vibrates and conveys the powder to the roller 5, preventing the powder from agglomerating during the transmission process and ensuring that the particle size of the powder flowing to the roller 5 is within the required range.

[0045] The grading and screening mechanism 2 includes several screening devices 201 stacked at intervals along the height direction. Each layer of screening devices 201 is connected to a first vibrator 202 that drives its vibration. The screening devices 201 in different layers are spaced apart to avoid affecting their respective vibration screening operations. Each screening device includes a screen 2011, which is used to screen powder. In adjacent screening devices 201, the mesh number of the screen 2011 in the upper layer is smaller than that in the lower layer. The mesh number describes the number of openings in the screen; the higher the mesh number, the finer the particles. Therefore, the grading and screening mechanism 2 in this invention is a structure where the powder obtained by screening layer by layer from top to bottom becomes increasingly fine, thus achieving step-by-step screening of the powder. This allows the powder that is agglomerated during storage to be gradually screened into particles, resulting in high screening efficiency and more uniform powder size. The screening device 201 has at least two layers.

[0046] The vibrating feeding mechanism of this utility model replaces the manual screening method used in the prior art by setting up a grading screening mechanism 2. It eliminates the need for small-batch, multiple feedings, reducing the labor intensity and labor costs of workers. Through step-by-step screening, the agglomerated powder is gradually screened into particles, resulting in high powder screening efficiency and more uniform powder size. This provides more uniform powder for film formation and improves the quality of the film.

[0047] Specifically, the screening device 201 is a box structure with a sealed bottom and an open top, including a screen 2011 and side baffles 2012, such as... Figure 5 As shown, a side baffle 2012 surrounds the edge of the screen 2011, which serves as the bottom plate of the box structure. The screen 2011 has mesh openings. The side baffle 2012 prevents powder from falling out from the side of the screening device 201 during vibration screening. The screening device 201 is mounted on the first support frame 203. Figure 3 and Figure 4 As shown, the first vibrator 202 drives the screening device 201 to vibrate, thereby achieving automatic screening of powder. Screening devices 201 in different layers are arranged correspondingly along the height direction so that the powder screened by the upper screening device 201 is received by the lower screening device 201. A second support frame 8 is provided at the bottom of the first support frame 203, as shown... Figure 1 and Figure 2 As shown, the bottom of the second support frame 8 is slidably connected to the slide rail 6, facilitating the sliding of the grading and screening mechanism 2 along the slide rail 6 to change its position. The slide rail 6 is fixedly connected to the support plate 7. When the vibrating conveying mechanism 3 is in operation, it is positioned at the bottom of the second support frame 8 to receive the powder sieved by the grading and screening mechanism 2. The power output end of the first vibrator 202 is connected to the side baffle 2012. The support plate 7 is connected to the main support structure.

[0048] To facilitate control of the discharge from the grading and screening mechanism 2, a discharge hopper 205 is provided at the outlet end of the bottom screening device 201. The discharge hopper 205 can be used to store a portion of the powder, such as... Figure 4 , Figures 6 to 8 As shown, the top opening of the discharge hopper 205 is connected to the outlet end of the bottom screening device 201. A first discharge port 207 is provided at the end of the discharge hopper 205 away from the screening device 201. A rotary paddle level switch 204 is provided inside the discharge hopper 205, positioned above the first discharge port 207. The rotary paddle level switch 204 is a level controller, including a motor 2041, a drive shaft 2042, and blades 2043. The motor 2041 is installed outside the discharge hopper 205, and its power output end is connected to the drive shaft 2042. The end of the drive shaft 2042 away from the motor 2041 is fixedly connected to the blades 2043. The motor 2041 drives the blades 2043 to rotate via the drive shaft 2042. When the powder stored in the discharge hopper 205 has not reached the position of the blade 2043, the blade 2043 is always rotating. When the powder stored in the discharge hopper 205 piles up to the height of the blade 2043, the blade 2043 is resisted. At this time, the motor 2041 stops working, the blade 2043 stops rotating, and the screening device 201 stops vibrating and screening to avoid excessive accumulation of powder in the discharge hopper 205.

[0049] To facilitate control of the opening size of the first discharge port 207, the first discharge port 207 is equipped with a first baffle plate 206 to control its opening size, such as... Figure 6 and Figure 7 As shown, a first baffle plate 206 is slidably connected to the first outlet 207. The first baffle plate 206 is driven by a first driving device, which moves the first baffle plate 206 to control the opening size of the first outlet 207. Preferably, two first baffle plates 206 are provided, and the two first baffle plates 206 are arranged opposite each other on the side of the first outlet 207. The two first baffle plates 206 move closer or further apart under the drive of the first driving device. To facilitate closing the first outlet 207, the first baffle plates 206 are arranged in a stepped shape. When the first outlet 207 is closed, the planes of the contact ends of the two oppositely arranged first baffle plates 206 are in contact.

[0050] In one embodiment, the first driving device for driving the first baffle 206 includes a drive screw 208, such as... Figure 9As shown, one end of the drive screw 208 is provided with a first forward thread section, and the other end is provided with a first reverse thread section. A first baffle plate 206 is threadedly connected to the first forward thread section, and another first baffle plate 206 is threadedly connected to the first reverse thread section. The end of the drive screw 208 is connected to the power output end of the first motor. When the first motor rotates, it drives the drive screw 208 to rotate, and the drive screw 208 drives the two first baffle plates 206 to move closer or further apart, thereby adjusting the opening width of the first discharge port 207. By adjusting the opening width, the discharge width is adjusted.

[0051] The vibrating conveying mechanism 3 includes a material box 301, such as... Figures 10 to 12 As shown, the material bin 301 is a box with an open top and a sealed bottom. The top opening of the material bin 301 corresponds to the discharge end of the grading and screening mechanism 2. Specifically, the top opening of the material bin 301 corresponds to the first discharge port 207, and is used to receive the material discharged from the first discharge port 207. The material bin 301 is connected to the second vibrator 311 that drives its vibration. The material bin 301 is provided with a second discharge port 312, which is located on the side wall of the material bin 301. Figure 10 and Figure 11 As shown. The second vibrator 311 is connected to the support plate 7, and the bottom of the material box 301 is connected to the second vibrator 311.

[0052] To facilitate adjustment of the material-accommodating space of the material bin 301, the inner cavity of the material bin 301 is provided with a first baffle 302 and a second baffle 304 with an adjustable interval. The first baffle 302, the second baffle 304, the side walls of the material bin 301, and the bottom plate form a receiving cavity 303 of the material bin 301. The width of the receiving cavity 303 is the interval between the first baffle 302 and the second baffle 304, and the width of the receiving cavity 303 is not less than the width of the first discharge port 207 to avoid material leakage during receiving. The width of the first discharge port 207 is aligned with the width of the receiving cavity 303. The width of the receiving cavity 303 is the same as the width of the second discharge port 312, thereby improving the consistency of the thickness of the discharged material along the width direction. When adjusting the interval between the first baffle 302 and the second baffle 304, the first baffle 302 and / or the second baffle 304 move along the length direction of the material bin 301 to change the installation position of the corresponding baffle. A material level sensor (not shown in the figure) is installed in the receiving chamber 303 to detect the material level in the material box 301.

[0053] To facilitate adjustment of the installation position, the bottom of the first baffle 302 is provided with a first connecting flange 3021, and the first connecting flange 3021 is provided with a first connecting through hole 3022. Correspondingly, the bottom plate of the material box 301 is provided with a third connecting through hole 3013 at a position corresponding to the first connecting through hole 3022, and each first connecting through hole 3022 is provided with a row of third connecting through holes 3013, such as... Figure 13 As shown, several third connecting through holes 3013 are arranged in the same row. The spacing of these third connecting through holes 3013 is adjusted according to different film width requirements. The first baffle 302 is connected to the bottom plate of the material box 301 through the first connecting through hole 3022. Similarly, the bottom of the second baffle 304 is provided with a second connecting flange 3041, and a second connecting through hole 3042 is provided on the second connecting flange 3041. Correspondingly, a fourth connecting through hole 3014 is provided on the bottom plate of the material box 301 at the position corresponding to the second connecting through hole 3042. Each second connecting through hole 3042 corresponds to a row of fourth connecting through holes 3014, such as... Figure 13 As shown, several fourth connecting through holes 3014 are provided in the same row. The spacing of the several fourth connecting through holes 3014 is set according to different film width adjustment requirements. The second baffle 304 is connected to the bottom plate of the material box 301 through the second connecting through hole 3042. The bottom end of the side wall of the material box 301 is provided with a third connecting flange 3011, and a fifth connecting through hole 3012 is provided on the third connecting flange 3011. The side wall of the material box 301 is connected to the bottom plate of the material box 301 through a connector connected in the fifth connecting through hole 3012.

[0054] To accommodate different film widths, the second discharge port 312 extends along the length of the corresponding side wall of the material box 301, such as... Figure 14 As shown, the second discharge port 312 is located near the bottom plate of the material box 301, and a third baffle 308 is provided at the top of the second discharge port 312. The length of the third baffle 308 is not less than the length of the second discharge port 312, and the third baffle 308 is slidably connected to the side wall where the second discharge port 312 is located. Figure 14 As shown, the second discharge port 312 is arranged along the length of the corresponding side wall of the material box 301. The bottom end of the side wall of the material box 301 corresponding to the second discharge port 312 is spaced a predetermined distance from the bottom surface of the material box 301. This predetermined distance is not less than the maximum discharge height required by the second discharge port 312. An elongated hole 309 extending along the height direction is provided on the side wall of the material box 301 corresponding to the second discharge port 312. The third baffle 308 is bolted to the position of the elongated hole 309. For ease of connection, the third baffle 308 is connected to the position of the elongated hole 309 by a wing bolt 310, as shown. Figure 11 As shown.

[0055] In one embodiment, an extension plate 307 for conveying powder is provided at the bottom of the material bin 301. The extension plate 307 is connected to the bottom plate of the material bin 301. The extension plate 307 is connected to the side of the second discharge port 312 away from the inner cavity of the material bin 301. The end of the extension plate 307 away from the material bin 301 is suspended at the feeding position of the roller 5 to facilitate feeding the roller 5. Alternatively, the extension plate 307 and the bottom plate of the material bin 301 are the same plate, such as... Figure 14 As shown, the extension plate 307 extends from the bottom plate of the material box 301 into the inner cavity of the second discharge port 312 away from the material box 301. The length of the extension plate 307 is not less than the length of the second discharge port 312, and the length of the extension plate 307 is parallel to the length of the second discharge port 312. In order to limit the feed width to the roller 5, a limiting structure for limiting the powder discharge width is provided on the extension plate 307.

[0056] Furthermore, the limiting structure includes a fourth baffle 305 and a fifth baffle 306 with an adjustable interval. The interval between the fourth baffle 305 and the fifth baffle 306 is the same as the interval between the first baffle 302 and the second baffle 304. The main body of the first baffle 302 corresponds to the main body of the fourth baffle 305, and the main body of the second baffle 304 corresponds to the main body of the fifth baffle 306. This facilitates the flow of material confined between the first baffle 302 and the second baffle 304 into the conveying space enclosed by the fourth baffle 305 and the fifth baffle 306, which have the same width. Figures 10 to 12 As shown.

[0057] In this design, the main bodies of the fourth baffle 305 and the fifth baffle 306 extend along the powder conveying direction. One end of the main body of the fourth baffle 305 and the fifth baffle 306 contacts the side wall of the material box 301, and the other end extends out of the end of the extension plate 307, thereby facilitating the reliable conveying of powder to the feeding position of the roller 5 and preventing material leakage during the powder conveying process. Specifically, as shown... Figure 15 As shown, the fourth baffle 305 includes a first main body 3051, a first auxiliary plate 3052, and a first connecting plate 3053. The first connecting plate 3053 has a first elongated through-hole 3054, which connects it to the extension plate 307. The first auxiliary plate 3052 is connected to the end of the first main body 3051 near the material box 301, and abuts against the side wall of the material box 301, improving the sealing performance between the fourth baffle 305 and the end of the material box 301. The first main body 3051 is used to limit the conveyed powder. By providing the first elongated through-hole 3054 on the first connecting plate 3053, which extends along the spacing adjustment direction of the fourth baffle 305, it is convenient for the fourth baffle 305 to be connected to the extension plate 307 as needed. A connecting threaded hole is provided on the extension plate 307 at a position corresponding to the first elongated through-hole 3054. Similarly, as... Figure 16 As shown, the fifth baffle 306 includes a second main body 3061, a second auxiliary plate 3062, and a second connecting plate 3063. The second connecting plate 3063 has a second elongated through-hole 3064, which connects it to the extension plate 307. The second auxiliary plate 3062 is connected to the end of the second main body 3061 near the material box 301, and abuts against the side wall of the material box 301, improving the sealing performance between the fifth baffle 306 and the end of the material box 301. The second main body 3061 is used to limit the conveyed powder. By providing the second elongated through-hole 3064 on the second connecting plate 3063, which extends along the spacing adjustment direction of the fifth baffle 306, it is convenient for the fifth baffle 306 to be connected to the extension plate 307 as needed. A connecting threaded hole is provided on the extension plate 307 at a position corresponding to the second elongated through-hole 3064.

[0058] To prevent powder from agglomerating within the receiving mechanism 1, the receiving mechanism 1 includes a feeding device 104 and a stirring device. The feeding device 104 has a feed inlet at its top and a third discharge outlet 107 at its bottom. The stirring device is rotatably mounted within the inner cavity of the feeding device 104. The feeding device 104 can be a cylindrical cylinder, such as... Figure 17 As shown. The stirring device is used to stir the powder placed in the feeding device 104, thereby breaking up the powder. The third discharge port 107 on the receiving mechanism 1 is normally closed, and only opens when the grading and screening mechanism 2 needs to feed material. The stirring operation of the stirring device is continuous.

[0059] In one embodiment, the stirring device includes a power unit 101 and a stirring element 105, such as... Figure 17 and Figure 18 As shown, the power output end of the power unit 101 is connected to the stirring element 105. Specifically, the stirring element 105 is connected to the power unit 101 via a connecting shaft 103, and the stirring element 105 is positioned near the bottom of the material holding device. A connecting bracket 102 is fixedly connected to the top of the material holding device 104, and the power unit 101 is connected to the connecting bracket 102. The connecting bracket 102 is used to support the power unit 101. Figure 18 As shown, the stirring element 105 can be a stirring fan blade. In other embodiments, the stirring element 105 can also be a stirring rod or a stirring tank, which is not limited here. The power unit 101 can be an electric motor.

[0060] To control whether the third discharge port 107 discharges material, a second baffle plate 106 with an adjustable opening is provided at the third discharge port 107. The second baffle plate 106 is rotatably mounted at the third discharge port 107, and its position is driven by a motor, thereby realizing the opening control of the third discharge port 107.

[0061] When the grading and screening mechanism 2 is not in the feeding state, the two first baffles 206 approach each other until their end faces press together, thus closing the first discharge port 207. At this time, the blades 2043 of the rotary paddle level switch 204 are still rotating. When the material in the discharge hopper 205 exceeds the set height, the blades 2043 stop rotating due to the resistance of the material. At this time, the second baffle 106 closes the third discharge port 107 under the drive of the motor, stopping the feeding of the grading and screening mechanism 2, and the screening device 201 stops screening. When the material level sensor (not shown in the figure) in the receiving chamber 303 detects that the material level in the receiving chamber 303 is lower than the set value, the first discharge port 207 opens to feed the material box 301. At this time, the powder discharge level in the discharge hopper 205 drops, the blade 2043 of the rotary paddle level switch 204 starts to rotate, the screening device 201 starts to screen, the second baffle plate 106 opens, and the third discharge port 107 starts to feed.

[0062] In one specific embodiment, the screening device 201 has six layers, arranged from top to bottom as follows: a first layer screening device, a second layer screening device, a third layer screening device, a fourth layer screening device, a fifth layer screening device, and a sixth layer screening device. The first layer screening device uses a 3-mesh screen, which uses high-frequency vibration to evenly disperse the powder and allow it to fall into the second layer screening device, which uses a 4-mesh screen and operates on the same principle as the first layer screening device. This continues in the same manner, with the third layer using a 5-mesh screen, the fourth layer using a 6-mesh screen, the fifth layer using a 7-mesh screen, and the sixth layer using an 8-mesh screen. After passing through the 8-mesh screen, the powder falls into the inner cavity of the discharge hopper 205. When the discharge hopper 205 is full, the upper multi-layer screening device 201 stops vibrating and screening. The opening and closing size of the first baffle plate 206 at the first discharge port 207 can be set by parameters. The opening and closing time of the first baffle plate 206 is controlled according to the amount of powder in the material area above the roller 5, so that a certain amount of powder is fed into the discharge port and then enters the material box 301 of the vibrating conveying mechanism 3 from the discharge port. The powder in the material box 301 is evenly fed into the area above the roller 5 under the vibration of the second vibrator 311.

[0063] The vibrating feeding mechanism of this utility model effectively solves the problem of powder agglomeration by setting up a receiving mechanism 1 and a grading and screening mechanism 2, and realizes uniform powder feeding. When the material box 301 is short of material, it automatically feeds the powder, reducing the requirements for manual feeding and eliminating the need for excessive manual intervention, thus greatly reducing labor costs. The feeding width can be adjusted according to the film forming width. The vibrating feeding mechanism includes a quick-installation structure, making adjustment more convenient.

[0064] This utility model also provides a feeding device for agglomerated powder, including a vibrating feeding mechanism. The discharge position of the vibrating feeding mechanism corresponds to the feed position of the film-forming roller 5. In order to smooth the powder at the feed position of the roller 5, a material smoothing mechanism 4 is also provided at the feed position of the roller 5. The vibrating feeding mechanism is the vibrating feeding mechanism described above.
