[0044] Referring to Figure 1 As shown, the battery powder feeding device described in the embodiment of the present application may include a bracket 10. The bracket 10 includes four columns 102 and a fixing plate 101 fixed to the top of the columns 102. The feeding hopper 11 passes through the fixing plate 101 and is welded and fixed to the fixing plate to fix the feeding hopper. The feeding port of the vibration pipe 12 is opened at the top of one end of the vibration pipe, and the discharging port of the vibration pipe 12 is opened at the bottom of the other end of the vibration pipe. The two ends of the first flexible connection 13 are respectively connected to the discharging port of the feeding hopper 11 and the feeding port of the vibration pipe 12. The first flexible connection 13 loosens the degree of freedom when adjusting the inclination angle of the vibration pipe 12, making it possible to adjust the inclination angle of the vibration pipe 12. The hanging plate 14 is welded and fixed to the discharging end of the feeding hopper 11. One end of the first hanging rod 15 is welded or fixed with a fastener to one side of the bottom of the hanging plate 14 near the feeding end of the vibration pipe 12, and the other end of the first hanging rod 15 is rotatably connected to the feeding end of the vibration pipe 12; the vibration pipe 12 can rotate around the other end of the first hanging rod 15. The number of the first hanging rods 15 is two, which are respectively located on both sides of the vibration pipe 12, so that the vibration pipe 12 can rotate more stably around the other end of the first hanging rod 15. The power end of the lifting assembly 16 is rotatably connected to the other side of the bottom of the hanging plate 14, and the lifting end of the lifting assembly 16 is rotatably connected to the outer wall of the vibration pipe 12.

[0045] The power end of the lifting assembly 16 provides power, so that the lifting end of the lifting assembly 16 drives the discharging end of the vibration pipe 12 to rotate around the bottom of the first hanging rod 15, adjusts the angle of the vibration pipe 12, and achieves the purpose of adjusting the flow rate of the battery powder in the vibration pipe 12, avoiding irreversible battery powder ratio errors caused by excessive flow rate of the battery powder at the discharging port of the vibration pipe 12.

[0046] In one embodiment, as Figure 1As shown in the figure, the lifting assembly 16 may include a motor 161a, a screw rod 162a, and a sleeve 163a. At the bottom of the other side of the hanging plate 14, two opposite support plates 167a are fixedly provided. Between the opposite support plates 167a, a rotatable rotating shaft 167b is provided. A third bushing 167c is sleeved on the rotating shaft 167b. A connecting block 167d is fixedly connected between the top of the third bushing 167c and the top of the motor 161a, so that the motor 161a is rotatably connected to the bottom of the other side of the hanging plate 14. The other side of the hanging plate 14 is the side away from the first suspension rod 15. The bottom of the sleeve 163a is rotatably connected to the outer wall of the vibrating pipe 12. One end of the screw rod 162a may be fixedly connected to the output shaft of the motor 161a through a coupling (not shown). An internal thread adapted to the thread of the screw rod 162a is provided in the sleeve 163a. The other end of the screw rod 162a is screwed into the sleeve 163a. The number of the lifting assemblies 16 may be two groups, which are respectively located on both sides of the vibrating pipe 12, and the vibrating pipe 12 can be lifted more stably.

[0047] Specifically, during the process of adjusting the angle of the vibrating pipe 12, the motor 161a rotates, driving the screw rod 162a to rotate, so that the sleeve 163a screwed to the screw rod 162a rises or falls. The sleeve 163a drives the discharge end of the vibrating pipe 12 to rotate around the bottom of the first suspension rod 15, adjusting the angle of the vibrating pipe 12, so as to achieve the purpose of adjusting the flow rate of the battery powder in the vibrating pipe 12, and avoid irreversible battery powder ratio errors caused by too large or too small inclination angles of the vibrating pipe 12, resulting in too large flow rates of the battery powder at the discharge port of the vibrating pipe 12.

[0048] In one embodiment, as Figure 3 shown, the lifting assembly 16 includes a telescopic cylinder 161b and a telescopic rod 162b. The telescopic cylinder 161b is rotatably connected to the bottom of the other side of the hanging plate 14. The other side of the hanging plate 14 is the side away from the first suspension rod 15. One end of the telescopic rod 162b is fixedly connected to the output end of the telescopic cylinder 161b, and the other end of the telescopic cylinder 161b is fixed to the outer wall of the discharge end of the vibrating pipe 12.

[0049] Specifically, during the process of adjusting the angle of the vibrating pipe 12, the telescopic cylinder 161b drives the telescopic rod 162b to rise or fall. The telescopic rod 162b drives the discharge end of the vibrating pipe 12 to rotate around the bottom of the first suspension rod 15, adjusting the angle of the vibrating pipe 12, so as to achieve the purpose of adjusting the flow rate of the battery powder in the vibrating pipe 12, and avoid irreversible battery powder ratio errors caused by too large flow rates of the battery powder at the discharge port of the vibrating pipe 12 due to too large flow rates of the battery powder in the vibrating pipe 12.

[0050] In one embodiment, as Figure 1As shown in the figure, the battery powder feeding device may further include a first shaft rod 163 and a first shaft sleeve 164 sleeved on the first shaft rod 163 and rotatably connected to the first shaft rod 163; one end of the first shaft rod 163 is fixedly connected to the outer wall of the feeding end of the vibration tube 12 by welding, and the other end of the first suspension rod 15 is welded or fixedly connected to the first shaft sleeve 164 by a fastener. The number of the first shaft rod 163 and the first shaft sleeve 164 is two, respectively located on both sides of the vibration tube 12, making the fixation of the vibration tube 12 more firm and the feeding end of the vibration tube 12 more stable during the rotation around the first shaft sleeve 164.

[0051] In one embodiment, as Figure 1 shown, the battery powder feeding device may further include a second shaft rod 165 and a second shaft sleeve 166; one end of the second shaft rod 165 is fixedly connected to the outer wall of the vibration tube 12 near the discharging end by welding, the second shaft sleeve 166 is sleeved on the second shaft rod 165 and rotatably connected to the second shaft rod 165, and the lifting end of the lifting assembly 16 is fixed to the second shaft sleeve 166. During the lifting process of the lifting end of the lifting assembly 16, the discharging end of the vibration tube 12 rotates around the bottom of the first suspension rod 15, and the vibration tube 12 makes an arc-shaped movement. The second shaft sleeve 166 is rotatably connected to the second shaft rod 165, so that the vibration tube 12 releases the rotational freedom and realizes the arc-shaped movement of the vibration tube 12.

[0052] In one embodiment, as Figure 1 shown, the battery powder feeding device may further include a humidity sensor 17 and a control unit 18. The sensing end of the humidity sensor 17 is located inside the vibration tube 12. The number of the humidity sensors 17 may be three, respectively located at the feeding end, the middle and the discharging end inside the vibration tube 12, which can monitor the humidity of the battery powder in the vibration tube 12 at multiple points, more accurately reflect the humidity of the battery powder in the vibration tube, and thus provide a reference for more accurately adjusting the angle of the vibration tube 12 in the future. The driving member of the lifting assembly 16 may be a motor 161a or a telescopic cylinder 161b, and the humidity sensors 17 are all electrically connected to the control unit 18.

[0053] The humidity sensor 17 detects the humidity of the battery powder in the vibration tube 12, and then adjusts the specific angle to be adjusted of the vibration tube 12 according to the humidity; specifically, as Figure 4 and Figure 5 shown, the left end of the vibration tube 12 is the feeding end, and the right end of the vibration tube is the discharging end; when the angle between the vibration tube 12 and the horizontal plane is positive, the discharging end of the vibration tube 12 is inclined upward, and when the angle between the vibration tube 12 and the horizontal plane is negative, the discharging end of the vibration tube 12 is inclined downward. For example:

[0054] When the humidity of the battery powder is between 46.5% RH and 53.0% RH, the angle range between the vibration tube 12 and the horizontal plane needs to be adjusted between +8.5° and +5.5°. At this time, the feeding speed of the battery powder in the vibration tube 12 is between 450.65 g / s and 556.30 g / s;

[0055] When the humidity of the battery powder is between 65.0% RH and 72.5% RH, the angle range between the vibration tube 12 and the horizontal plane needs to be adjusted between -6° and -22°. At this time, the feeding speed of the battery powder in the vibration tube 12 is between 406.68 g / s and 463.45 g / s.

[0056] In one embodiment, as Figure 1 shown, the battery powder feeding device may further include a vibrator 19; the vibrator 19 is fixed to the bottom of the vibration tube 12. The vibrator 19 vibrates the vibration tube 12 to improve the fluidity of the battery powder in the vibration tube 12.

[0057] In one embodiment, as Figure 4 shown, the battery powder feeding device may further include a feeding tube 20, a second flexible connection 21 and a horizontal adjustment and positioning assembly 22; both ends of the second flexible connection 21 are respectively fixed to the feeding tube 20 and the discharging end of the vibration tube 12. The battery powder in the vibration tube 12 falls into the feeding tube 20 through the second flexible connection 21 and then falls into the next process that needs to be fed with battery powder through the feeding tube 20. The second flexible connection 21 loosens the degree of freedom for adjusting the position when the feeding tube 20 is docked.

[0058] The horizontal adjustment and positioning assembly 22 includes a positioning plate 221 and a positioning rod 222. The positioning plate 221 is fixed below the discharging end of the vibration tube 12 through a second suspension rod 224. One end of the second suspension rod 224 is fixed to the bottom of the vibration tube 12, and the other end of the second suspension rod 224 is fixed to the top of the positioning plate 221. One end of the positioning rod 222 is fixed to the outer wall of the feeding tube 20, and the other end of the positioning rod 222 is placed on the positioning plate 221.

[0059] Specifically, during the process of adjusting the feeding tube 20, hold the positioning rod 222 and move the positioning rod 222 to align the feeding tube 20 with the feeding end of the next process to be docked. After alignment, place the positioning rod 222 on the positioning plate 221, and then fix the feeding tube 20 to the feeding end of the next process to be docked, making the docking of the feeding tube 20 with the feeding end of the next process more convenient and improving the docking speed.

[0060] In one embodiment, the horizontal adjustment positioning assembly 22 further includes a placement plate 223. The placement plate 223 is fixed to the bottom of the other end of the positioning rod 222, and the placement plate 223 is placed on the positioning plate 221. After the blanking pipe 20 is docked, the placement plate 223 is placed on the positioning plate 221. The placement plate 223 can increase the contact area with the positioning plate 221, make the positional relationship between the positioning rod 222 and the positioning plate 221 more firm, reduce the movement of the position of the blanking pipe 20 after positioning, and when fixing the docking end of the blanking pipe 20 and the next process, it will not be affected by the shaking or movement of the blanking pipe 20.

[0061] In one embodiment, a number of lower convex points 2211 are provided on the positioning plate 221, and upper convex points 2231 corresponding to the lower convex points 2211 are provided on the placement plate 223. The upper convex points 2231 and the lower convex points 2211 are arranged in a staggered manner. The upper convex points 2231 are placed on the lower convex points 2211, which can increase the friction between the positioning plate 221 and the placement plate 223, and further make the positional relationship between the blanking pipe 20 and the positioning plate 221 more firm.

[0062] Describe the overall working process of the device:

[0063] Put battery powder into the hopper 11. The battery powder enters the vibrating pipe 12 through the first flexible connection 13. At this time, the motor 161a or the telescopic cylinder 161b is started to drive the discharge end of the vibrating pipe 12 to rise or fall. At the same time, the humidity sensor 17 detects the humidity of the battery powder, and the control unit 18 calculates the required angle between the vibrating pipe 12 and the horizontal plane according to the humidity of the battery powder. The vibrating pipe 12 rotates around the first shaft rod 163. After rotating the vibrating pipe 12 to the above required angle, the vibrator 19 vibrates the vibrating pipe 12 to make the battery powder enter the blanking pipe 20 from the discharge end of the vibrating pipe 12.

[0064] Beneficial effects:

[0065] Avoid irreversible battery powder ratio errors caused by the excessive or too small inclination angle of the vibrating pipe 12, resulting in too large a flow rate of the battery powder at the discharge port of the blanking pipe 20

[0066] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
