[0018] Beneficial effects of the present invention:

[0019] 1. When the die head spits out the material, the positive electrode slurry and AT9 Juncong flow out from the lip position. By dividing the receiving rack into a recovery chamber and a waste chamber, the positive electrode slurry flows vertically downward from the lip under the gravity into the recovery chamber directly below. A dividing rack is set between the waste chamber and the bottom plate. The dividing rack is set below the AT9 flow channel. AT9 flows out from the lip and falls onto the dividing rack. The mixed waste formed by AT9 and a small amount of positive electrode slurry flows from the dividing rack into the waste chamber to prevent the slurry from being collected in the barrel and cannot be recycled.

[0020] 2. The air pump drives the air intake port to inhale air. When the adjusting knob is turned at the same time, the adjusting cylinder drives the connecting rod to move through the threaded cooperation, the connecting rod drives the push rod to move, and the push rod drives the adjusting plate to move through the inclined surface. The air intake port is in a trapezoidal shape with an opening facing outward. The air intake port sucks the AT9 expelled from the lip toward the middle through suction force, thereby preventing the AT9 from expanding to both sides during the exhalation process and exceeding the dividing rack and falling into the recovery barrel. The adjusting plate is driven to move by the adjusting knob, and the air intake channel of the air intake port can be changed through the adjusting plate to change the suction force so that different slurries can be used.

[0021] 3. When the adjusting knob drives the adjusting plate to move to both sides, the air intake channel is reduced to increase the suction force of the air intake port. At the same time, the adjusting rod is driven up through the inclined surface of the L-shaped support rod, thereby driving the rotating drum up and reducing the distance between the rotating drum and the push plate. The height of the push plate driven by the push rod is increased, so that the push plate can push the slurry more, making the slurry flatter more quickly and preventing the occurrence of different heights during the slurry coating process.

[0022] In summary, the equipment has the advantages of preventing slurry pollution and stable slurry recovery, and is particularly suitable for the field of lithium battery coating technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0039] Embodiment 1

[0040] like Figures 1 to 13As shown, a lithium battery positive electrode slurry AT9 diversion recovery method includes an operating platform 1, a side plate 2, and a die assembly 3. The side plates are arranged on both sides of the operating platform 1. The die assembly 3 is divided into an upper die 4 and a lower die 5. A lip 6 is formed between the upper die 4 and the lower die 5. The lip 6 is used to spit out the positive electrode slurry and AT9 for coating. A feed trough 7 is provided on the surface of the lower die 5. A plurality of air intake ports 8 are provided below the feed trough 7. An air intake channel 9 communicating with the plurality of air intake ports 8 is further provided inside the lower die 5. Adjustment plates 10 and a push rod 11 for driving the adjustment plate 10 to move are slidably provided on both sides of the air intake port 8. A push rod 11 for driving the push rod 11 is provided on the side of the lower die 5. A movable adjustment knob 12, a plurality of push plates 13 are slidably arranged on the surface of the feed chute 7, a rotating drum 14 is rotatably arranged below the feed chute 7, a motor 15 for driving the rotating drum 14 to rotate is arranged on the side of the lower die head 5, a plurality of push rods 16 are staggeredly arranged on the surface of the rotating drum 14, and the push plates 13 are driven up by the push rods 16 while the rotating drum 14 rotates, the adjustment button drives the push rod 11 to move forward and backward while driving the rotating drum 14 up and down, and the push rod 11 moves while driving the adjustment plate 10 to change the size of the air intake port 8, and the rotating drum 14 moves while changing the distance between the push rod 16 and the push plate 13, thereby changing the rising height of the push plate 13.

[0041] like Figure 1 , Figure 7 As shown, a transmission roller 21 is rotatably arranged between the side plates 2 on both sides, a bottom plate 22 is slidably arranged on the side plate 2, the die head assembly 3 is arranged on the bottom plate 22, a material receiving rack 23 is arranged between the bottom plate 22 and the transmission roller 21, a recovery chamber 24 and a waste chamber 25 are arranged on the material receiving rack 23, a material distribution rack 26 is set between the waste chamber 25 and the bottom plate 22, and the material distribution rack 26 is arranged below the AT9 flow channel.

[0042] In addition, by setting up the dividing rack 26 below the AT9 flow channel, the positive electrode slurry flow channel is set between the AT9 flow channels, when the die head spits out the material, the positive electrode slurry and AT9 both flow out along the lip position, the positive electrode slurry is vertically left from the lip by gravity into the recovery chamber 24, and the AT9 is left by gravity onto the dividing rack 26, and a small amount of the positive electrode slurry will flow into the dividing rack 26 during the process of vertically leaving, and the dividing rack 26 will flow the mixed waste of AT9 and a small amount of positive electrode slurry into the waste chamber 25, so as to avoid contamination in the recovery barrel and inability to recycle.

[0043] like Figure 1 , Figure 6 , Figure 8As shown, the air intake port 8 is trapezoidal and its opening is arranged outward, the adjusting plate 10 is arranged parallel to the side of the air intake port 8, a limiting rod 31 is arranged on the side of the adjusting plate 10, the limiting rod 31 is slidably arranged on the side of the air intake port 8, the push rod 11 is arranged on the limiting rod 31, the contact surface between the push rod 11 and the adjusting plate 10 is arranged to be an inclined surface, a connecting rod 33 is arranged on the side of the push rod 16, an adjusting cylinder 34 is arranged on the side of the adjusting knob 12, the connecting rod 33 and the adjusting cylinder 34 are threadedly matched, and an air pump 35 for allowing the air intake port 8 to inhale is arranged on the operating platform 1.

[0044] It is worth explaining here that suction is generated at the air inlet 8 by the air pump 35, and when the lip 6 spits out AT9, the air inlet 8 draws the outflowing AT9 to both sides by suction, thereby preventing AT9 from spreading to both sides and thus exceeding the dividing rack 26 and falling into the recovery chamber 24. When a slurry with higher viscosity is used, the suction force of the air inlet 8 is insufficient, and the adjusting knob 12 is rotated, and the adjusting knob 12 drives the adjusting cylinder 34 to rotate, and the adjusting cylinder 34 drives the connecting rod 33 to move through a threaded connection, and the connecting rod 33 drives the push rod 11 to move, and the push rod 11 drives the adjusting plate 10 to move to both sides through the inclined surface, thereby reducing the suction channel of the air inlet 8, thereby increasing the suction force of the air inlet 8.

[0045] like Figure 4 , Fig. 9 As shown, an adjusting cavity 41 is provided in the lower die head 5, the rotating cylinder 14 is arranged in the adjusting cavity 41, slide grooves 42 are provided on both sides of the adjusting cavity 41, and slide rods 43 are provided on the slide grooves 42. A slider 44 is provided on the side of the rotating cylinder 14, and the slider 44 is slidably set on the slide rod 43. The rotating cylinder 14 is rotatably set on the slider 44, and a support rod 45 is provided on the lower end surface of the push plate 13. The support rod 45 is slidably set in the lower die head 5, and a spring is provided between the support rod 45 and the lower die head 5.

[0046] It should be noted that the rotating drum 14 is slidably set on the sliding rod 43 through a slider 44, the slider 44 is elastically set on the sliding rod 43 through a spring, and the rotating drum 14 is rotatably set on the slider 44. The rotating drum 14 rotates under the action of the motor and drives the push rod 16 to rotate. The push rod 16 drives the push plate 13 to rise through the inclined surface, and several push plates 13 are staggered to flatten the slurry in the lower die head 5, so that the slurry flows out from the lip more smoothly.

[0047] like Figure 6 As shown, an L-shaped support rod 51 is clamped on the connecting rod 33, and an adjusting rod 52 is arranged at the lower end of the rotating drum 14, and the contact surfaces of the L-shaped support rod 51 and the adjusting rod 52 are both arranged to be inclined surfaces.

[0048] It is worth mentioning here that when the adjusting knob 12 drives the connecting rod 33 to move and drives the rotating drum 14 to rise through the L-shaped support rod 51, so that the connecting rod 33 drives the adjusting plate 10 to change the suction channel of the suction port 8 to increase the suction force of the suction port 8, it means that the viscosity of the slurry is relatively large and the suction force needs to be adjusted. At the same time, by driving the rotating drum 14 to rise, the distance between the rotating drum 14 and the pushing plate 13 is reduced, thereby increasing the pushing height of the pushing plate 13 and increasing the material withdrawal effect of the pushing plate 13.

[0049] like Fig. 9 As shown, a spring sleeved on the slide rod 43 is arranged between the slide block 44 and the slide slot 42 .

[0050] like Figure 6 As shown, the push plate 13 is arranged as an inclined surface and the inclined surface is arranged toward the lip 6, and the inclined surface of the push plate 13 is inclined toward both sides.

[0051] As shown in the figure, a recovery channel 81 and a recovery bucket 82 connected to the recovery channel 81 are provided at the lower end of the recovery chamber 24, and a waste channel 83 and a waste bucket 84 connected to the waste channel 83 are provided at the lower end of the waste chamber 25.

[0052] It is worth mentioning that the positive electrode slurry in the recovery chamber 24 is uniformly recovered into the recovery barrel 82 through the recovery channel 81 , and the AT9 and a small amount of positive electrode slurry in the waste chamber 25 enter the waste barrel 84 through the waste channel 83 .

[0053] like Figure 6 As shown, the adjusting knob 12 is arranged on the end face of the lower die head 5 and has a rough surface.

[0054] It is explained here that by arranging the adjusting knob 12 on the end surface of the lower die head 5 and providing a rough surface, manual twisting can be facilitated.

[0055] The width of the air inlet 8 is smaller than the width of the material distribution rack 26 .

[0056] It should be mentioned that by making the width of the air intake port 8 smaller than the material distribution rack 26, the outflow width of the AT9 slurry from the air intake port 8 can be smaller than the material distribution rack 26, thereby preventing the AT9 slurry from flowing out of the material distribution rack 26 and falling into the recovery barrel 82 to cause slurry contamination.
