[0047] The present application is described in detail below through specific embodiments:

[0048] See also Figure 1 and Figure 2, an embodiment of the present application provides a feeding device 100, which includes a silo 110, a material tapping assembly 120 and a driving assembly 121. The silo 110 has a feed port 111 and a discharge port 112 along its height direction, and the discharge port 112 is located below the feed port 111. The silo 110 is used to hold materials; the material tapping assembly 120 includes a first material tapping roller 122 and a second material tapping roller 123 arranged in parallel in the silo 110 along a first direction, the first material tapping roller 122 and the second material tapping roller 123 can rotate around a first rotation axis and a second rotation axis extending in a second direction, respectively, and the first direction, the second direction and the height direction of the silo 110 are perpendicular to each other; the driving assembly 121 is arranged on the outside of the silo 110, connected to the first material tapping roller 122 and the second material tapping roller 123, and is used to drive the first material tapping roller 122 and the second material tapping roller 123 to rotate relative to each other to refine the material and transport it to the discharge port 112.

[0049] The height direction of the silo 110 is Figure 1 Optionally, the silo 110 is a symmetrical structure, and the silo 110 includes a first silo and a second silo that are interconnected, wherein the first silo is close to the feed port 111, the second silo is close to the discharge port 112, and the material shifting assembly 120 is located in the second silo and close to one end of the first silo, so that when the material shifting assembly 120 stops working, the material will accumulate in the first silo.

[0050] Furthermore, a protective shell may be provided on the outside of the silo 110 , so that the driving assembly 121 is provided on the protective shell, and a driving shaft of the driving assembly 121 passes through the protective shell and extends into the silo 110 to connect with the first material dispensing roller 122 and the second material dispensing roller 123 .

[0051] Optionally, the first silo and the second silo are integrally formed, thereby simplifying the assembly process of the silo 110 .

[0052] In addition, the structure in which the first material-dividing roller 122 and the second material-dividing roller 123 can refine the material when rotating includes but is not limited to providing refinement teeth, refinement brushes, etc. on the peripheral walls of the first material-dividing roller 122 and the second material-dividing roller 123.

[0053] In addition, the first direction mentioned above refers to Figure 1 The second direction is the direction indicated by the X arrow. Figure 1 In the direction indicated by the Y arrow, the driving component 121 can be a rotary motor, a rotary motor, etc.

[0054] Since the first material dispensing roller 122 and the second material dispensing roller 123 are arranged along the first direction in the silo 110, and the driving component 121 can drive the first material dispensing roller 122 and the second material dispensing roller 123 to rotate to refine the material, when conveying the material to the discharge port 112, the first material dispensing roller 122 and the second material dispensing roller 123 can convey the material falling on the two to the discharge port 112 at a preset speed, and at the same time, can refine the conveyed material, so that it can avoid the occurrence of bridging between the material falling on the electrode sheet and the material in the silo 110, thereby ensuring the continuity of the film formation of the material on the electrode sheet, and avoid the accumulation of the material falling on the electrode sheet, thereby improving the uniformity of the material falling on the electrode sheet, thereby improving the preparation quality of the battery.

[0055] In addition, the rotation speed of the first feed roller 122 and the second feed roller 123 can be adjusted by controlling the driving assembly 121, so as to control the speed of conveying materials by the first feed roller 122 and the second feed roller 123, thereby meeting the production speed requirement of the electrode sheet.

[0056] In addition, optionally, the discharge port 112 of the silo 110 is an open structure, so that the material bridging phenomenon caused by the material falling through the discharge port 112 can be further avoided.

[0057] It should also be noted that the first material roller 122 and the second material roller 123 rotate relative to each other. It should be understood that the first material roller 122 and the second material roller 123 rotate in opposite directions, or the first material roller 122 and the second material roller 123 rotate in the same direction, but there is a speed difference between the first material roller 122 and the second material roller 123.

[0058] In some possible embodiments, see Figure 2 , Figure 3 and Figure 4 A plurality of first material-dividing teeth 1221 are arranged on the peripheral wall of the first material-dividing roller 122, and the plurality of first material-dividing teeth 1221 are evenly distributed along the circumference of the first material-dividing roller 122; a plurality of second material-dividing teeth 1231 are arranged on the peripheral wall of the second material-dividing roller 123, and the plurality of second material-dividing teeth 1231 are evenly distributed along the circumference of the second material-dividing roller 123, and the plurality of second material-dividing teeth 1231 and the plurality of first material-dividing teeth 1221 are staggered with each other along the second direction.

[0059] The above-mentioned multiple refers to a number of three or more.

[0060] In addition, the above-mentioned multiple second material-digging teeth 1231 and the multiple first material-digging teeth 1221 are staggeredly arranged along the second direction, which means that when the first material-digging roller 122 and the second material-digging roller 123 rotate, the first material-digging teeth 1221 on the first material-digging roller 122 are located between two adjacent second material-digging teeth 1231 on the second material-digging roller 123. In other words, there is no situation where the tooth tops of the first material-digging teeth 1221 on the first material-digging roller 122 and the tooth tops of the second material-digging teeth 1231 on the second material-digging roller 123 are abutted against each other.

[0061] Since the plurality of first material-dividing teeth 1221 are evenly spaced along the circumference of the first material-dividing roller 122, and the plurality of second material-dividing teeth 1231 are evenly spaced along the circumference of the second material-dividing roller 123, when the first material-dividing roller 122 and the second material-dividing roller 123 rotate, the first material-dividing teeth 1221 and the second material-dividing teeth 1231 can divert a corresponding amount of material to be transported to the discharge port 112, thereby further ensuring the uniformity of material dropping.

[0062] Furthermore, since the plurality of second material-dividing teeth 1231 are staggered with the plurality of first material-dividing teeth 1221 , the first material-dividing teeth 1221 and the second material-dividing teeth 1231 can refine the conveyed material during the rotation of the first material-dividing roller 122 and the second material-dividing roller 123 .

[0063] In some possible embodiments, see Figure 4 The first material-stripping tooth 1221 is inclined from the tooth root to the tooth top along the rotation direction of the first material-stripping roller 122 , and the second material-stripping tooth 1231 is inclined from the tooth root to the tooth top along the rotation direction of the second material-stripping roller 123 .

[0064] The first feeding roller 122 rotates in the following direction: Figure 4 The direction indicated by the arrow z1 and the rotation direction of the second material feeding roller 123 are as follows: Figure 4 The direction indicated by the arrow z2.

[0065] In addition, the tooth root of the first material-pulling tooth 1221 refers to the end close to the first material-pulling roller 122, and the tooth top refers to the end away from the first material-pulling roller 122. Similarly, the tooth root of the second material-pulling tooth 1231 refers to the end close to the second material-pulling roller 123, and the tooth top refers to the end away from the second material-pulling roller 123.

[0066] Since the first material-dividing tooth 1221 is inclined from the tooth root to the tooth top along the rotation direction of the first material-dividing roller 122, and the second material-dividing tooth 1231 is inclined from the tooth root to the tooth top along the rotation direction of the second material-dividing roller 123, when the first material-dividing roller 122 and the second material-dividing roller 123 rotate towards each other, the first material-dividing tooth 1221 and the second material-dividing tooth 1231 cooperate to refine larger particles of material and force the material to be fed to the discharge port 112, thereby ensuring the continuity and uniformity of material falling.

[0067] Of course, in other embodiments, if both the first material-moving roller 122 and the second material-moving roller 123 are provided with radially-directed material-moving brushes, the first material-moving roller 122 and the second material-moving roller 123 may rotate in the same direction.

[0068] In some possible embodiments, see Figure 1 The driving assembly 121 includes a first driving member 1211 and a second driving member 1212 . The first driving member 1211 is connected to the first material-moving roller 122 , and the second driving member 1212 is connected to the second material-moving roller 123 .

[0069] By connecting the first driving member 1211 to the first material-discharging roller 122 and the second driving member 1212 to the second material-discharging roller 123, the rotation speeds of the first material-discharging roller 122 and the second material-discharging roller 123 can be independently controlled. In other words, by adjusting the rotation speed ratio between the first driving member 1211 and the second driving member 1212, the material refining effect can be further optimized.

[0070] For example, the first driving member 1211 and the second driving member 1212 may be controlled separately so that the rotation speeds of the first material-digging roller 122 and the second material-digging roller 123 are different.

[0071] In some possible embodiments, see Figure 5 The feeding device 100 also includes a first bearing seat 131 and a second bearing seat 132 which are movably arranged on the silo 110 along the first direction. The output shaft of the first driving member 1211 is connected to the first material-discharging roller 122 through the first bearing seat 131, and the output shaft of the second driving member 1212 is connected to the second material-discharging roller 123 through the second bearing seat 132. The first bearing seat 131 and the second bearing seat 132 can approach or move away from each other in the first direction to adjust the distance between the first material-discharging roller 122 and the second material-discharging roller 123.

[0072] Since the output shaft of the first driving member 1211 is connected to the first material removal roller 122 through the first bearing seat 131, and the output shaft of the second driving member 1212 is connected to the second material removal roller 123 through the second bearing seat 132, the friction between the output shaft of the first driving member 1211 and the silo 110 and between the output shaft of the second driving member 1212 and the silo 110 is reduced.

[0073] In addition, since the first bearing seat 131 and the second bearing seat 132 can be moved closer to or farther away from each other along the first direction, when the first bearing seat 131 and the second bearing seat 132 are adjusted to be closer to or farther away from each other along the first direction, the distance between the first material transfer roller 122 and the second material transfer roller 123 can be adjusted, thereby adjusting the amount of material passing through the first material transfer roller 122 and the second material transfer roller 123.

[0074] For example, when the amount of material falling needs to be increased, the first bearing seat 131 and the second bearing seat 132 are moved away from each other along the first direction. Otherwise, the first bearing seat 131 and the second bearing seat 132 are moved closer to each other along the first direction.

[0075] In addition, optionally, the output shaft of the first driving member 1211 is connected to the first bearing seat 131 through a first coupling, and the output shaft of the second driving member 1212 is connected to the second bearing seat 132 through a second coupling.

[0076] In some possible embodiments, see Figure 5 and Figure 6 The feeding device 100 further includes a guide structure 140 , which guides along a first direction, and the first bearing seat 131 and the second bearing seat 132 are disposed on the silo 110 through the guide structure 140 .

[0077] Therefore, by setting up the guide structure 140, and the first bearing seat 131 and the second bearing seat 132 are set on the silo 110 through the guide structure 140, the consistency of the movement trajectories of the first bearing seat 131 and the second bearing seat 132 in the first direction can be ensured, thereby avoiding the first bearing seat 131 and the second bearing seat 132 deviating from the first direction during the movement and getting stuck.

[0078] In addition, the guide structure 140 has various structures. In one possible structure, see Figure 5 and Figure 6 The guide structure 140 includes a guide rail 141 and a first slider 142 and a second slider 143 slidably disposed on the guide rail 141 . The guide rail 141 extends along a first direction. The first bearing seat 131 is disposed on the first slider 142 , and the second bearing seat 132 is disposed on the second slider 143 .

[0079] Since the first slider 142 and the second slider 143 are provided on the guide rail 141, and the first bearing seat 131 is provided on the first slider 142, and the second bearing seat 132 is provided on the second slider 143, the first bearing seat 131 and the second bearing seat 132 can be guided by providing a guide rail 141, and the structure is simple.

[0080] Of course, in some other possible structures, the guide structure 140 may also include a screw structure.

[0081] In some possible embodiments, see Figure 5 and Figure 6The feeding device 100 also includes a first limit member 151 disposed on the silo 110 , and the first limit member 151 is located between the first bearing seat 131 and the second bearing seat 132 to limit the minimum distance between the first bearing seat 131 and the second bearing seat 132 .

[0082] Specifically, the first limiting member 151 includes a connecting portion and a limiting portion that are interconnected, wherein the connecting portion is connected to the side wall of the guide rail 141, the limiting portion extends in a direction away from the silo 110 and is located between the first bearing seat 131 and the second bearing seat 132, and the thickness of the limiting portion in the first direction is the minimum distance between the first bearing seat 131 and the second bearing seat 132.

[0083] Therefore, by setting the first limit member 151, the first bearing seat 131 and the second bearing seat 132 can be prevented from continuing to move closer to each other in the first direction, that is, the minimum distance between the first bearing seat 131 and the second bearing seat 132 is ensured, thereby avoiding interference between the first material tooth 1221 on the first material roller 122 and the second material tooth 1231 on the second material roller 123, thereby ensuring the stability of the first material tooth 1221 and the second material tooth 1231 in cooperating with each other to convey materials.

[0084] In some possible embodiments, see Figure 7 The feeding device 100 also includes two second limiting members 152 arranged on the silo 110, and the two second limiting members 152 are arranged at intervals along the first direction. The first bearing seat 131 and the second bearing seat 132 are located between the two second limiting members 152 to limit the maximum distance between the first bearing seat 131 and the second bearing seat 132.

[0085] Among them, the second limit member 152 can be a limit block, a limit rod or other structures. For example, when the second limit member 152 is a limit rod, by making the ends of the limit rod respectively abut against the first bearing seat 131 and the second bearing seat 132, the first bearing seat 131 and the second bearing seat 132 can be prevented from moving away from each other in the first direction.

[0086] Therefore, by setting two second limit members 152 and making the first bearing seat 131 and the second bearing seat 132 located between the two second limit members 152, when the first bearing seat 131 and the second bearing seat 132 move away from each other in the first direction, when the first bearing seat 131 and the second bearing seat 132 respectively abut against the two second limit members 152, the two second limit members 152 can prevent the first bearing seat 131 and the second bearing seat 132 from continuing to move away from each other in the first direction, thereby preventing the first bearing seat 131 and the second bearing seat 132 from detaching from the silo 110.

[0087] In some possible embodiments, see Figure 7 The feeding device 100 further includes an adjusting member 160 disposed on the silo 110 , and the adjusting member 160 is used to adjust the distance between the first bearing seat 131 and the second bearing seat 132 .

[0088] By setting the adjusting member 160, the distance between the first bearing seat 131 and the second bearing seat 132 can be adjusted according to the material drop speed and quantity, and then the distance between the first material-dispensing roller 122 and the second material-dispensing roller 123 can be adjusted, so as to meet different production requirements of electrode sheets. In addition, by setting the adjusting member 160, the distance between the first material-dispensing roller 122 and the second material-dispensing roller 123 can also be determined according to different looseness of the material and the material in different states.

[0089] In addition, the adjustment member 160 can automatically adjust the distance between the first bearing seat 131 and the second bearing seat 132 , or can manually adjust the distance between the first bearing seat 131 and the second bearing seat 132 .

[0090] In some possible embodiments, see Figure 7 The feeding device 100 also includes two mounting plates 163 spaced apart along the first direction; the adjusting member 160 includes a first adjusting member 161 and a second adjusting member 162, the first adjusting member 161 and the second adjusting member 162 are rotatably arranged on the two mounting plates 163 respectively, the first adjusting member 161 is also threadedly connected to the first bearing seat 131, and the second adjusting member 162 is also threadedly connected to the second bearing seat 132.

[0091] The first adjusting member 161 and the second adjusting member 162 may be adjusting screws, adjusting bolts, adjusting lead screws, etc.

[0092] Therefore, when the first adjusting member 161 is tightened toward the first bearing seat 131 and the second adjusting member 162 is tightened toward the second bearing seat 132, the first bearing seat 131 and the second bearing seat 132 can be brought closer to each other, thereby bringing the first material transfer roller 122 and the second material transfer roller 123 closer to each other. Conversely, when the first adjusting member 161 is unscrewed toward the first bearing seat 131 and the second adjusting member 162 is unscrewed toward the second bearing seat 132, the first bearing seat 131 and the second bearing seat 132 can be brought closer to each other, thereby bringing the first material transfer roller 122 and the second material transfer roller 123 closer to each other. It can be seen that by rotating the first adjusting member 161 and the second adjusting member 162, the first bearing seat 131 and the second bearing seat 132 can be independently controlled to move in the first direction, so as to flexibly adjust the distance between the first material transfer roller 122 and the second material transfer roller 123.
