[0018] Embodiment: As Figures 1-5 shown, the present utility model provides an intelligent tablet pressing device for a sodium-ion battery electrode sheet, including a bottom plate 1. Two mirror-image distributed fixing plates 2 are fixedly installed at the top end of the bottom plate 1. Two mutually cooperating mounting shafts 21 are installed at both ends of the opposite sides of the two fixing plates 2. A support frame 3 is fixedly installed in the middle of the top ends of the two fixing plates 2. An installation plate 32 is provided in the middle of the support frame 3. An electric push rod 31 is fixedly installed in the middle of the top end of the support frame 3. The middle of the top end of the installation plate 32 is fixedly installed at the driving end of the electric push rod 31. A first rolling shaft 34 is rotatably installed at the lower part of the installation plate 32. A third bevel gear 341 is fixedly installed on one side of the first rolling shaft 34 passing through the installation plate 32. A second rolling shaft 35 is rotatably installed in the middle of the opposite sides of the two fixing plates 2. A fourth bevel gear 351 is fixedly installed on one side of the second rolling shaft 35 passing through the fixing plate 2. A rotating shaft 12 is rotatably installed at the lower part of one side of the support frame 3. The upper part of the rotating shaft 12 is slidably clamped with a second bevel gear 14. The second bevel gear 14 is meshed and connected with the third bevel gear 341. The top end of the second bevel gear 14 is rotatably installed at the lower part of one side of the installation plate 32. A first bevel gear 13 is fixedly installed at the lower part of the rotating shaft 12. The first bevel gear 13 is meshed and connected with the fourth bevel gear 351. A driving assembly is provided on one side of the top end of the bottom plate 1.

[0019] A limiting roller 4 is rotatably installed at the upper part of one side of the two fixing plates 2. A screw rod 42 is rotatably installed in the middle of the limiting roller 4. The outer surface of both sides of the screw rod 42 is provided with left and right threads. Limiting plates 43 are threadedly installed on both sides of the screw rod 42.

[0020] The driving assembly includes a first motor 11. The bottom end of the first motor 11 is fixedly installed on one side of the top end of the bottom plate 1. The bottom end of the rotating shaft 12 is fixedly installed at the driving end of the first motor 11. By setting the first motor 11 and driving by the first motor 11, the first bevel gear 13 and the second bevel gear 14 can be rotated, thereby driving the third bevel gear 341 and the fourth bevel gear 351 meshed and connected therewith to rotate, thereby driving the first rolling shaft 34 and the second rolling shaft 35 to rotate, that is, performing tablet pressing treatment on the electrode sheet passing between the first rolling shaft 34 and the second rolling shaft 35.

[0021] Two mirror-symmetrically distributed sliding grooves 121 are provided in the upper part of the rotating shaft 12. The middle part of the second bevel gear 14 is slidably clamped inside the sliding groove 121. By providing the sliding groove 121 and slidably clamping the second bevel gear 14 inside the sliding groove 121, the second bevel gear 14 can be driven to rotate by the rotation of the rotating shaft 12 while being able to slide up and down on the outer surface of the rotating shaft 12 without being affected.

[0022] A limiting block 33 is fixedly installed in the middle of one side of the mounting plate 32. A second limiting groove 331 is provided in the middle of one side of the support frame 3. The limiting block 33 is slidably clamped inside the second limiting groove 331. By providing the limiting block 33 and the second limiting groove 331 and slidably clamping the limiting block 33 installed on one side of the mounting plate 32 inside the second limiting groove 331, the mounting plate 32 can move more stably when driven by the electric push rod 31 to move up and down.

[0023] A first limiting groove 321 is provided on one side of the support frame 3. One side of the mounting plate 32 is slidably clamped inside the first limiting groove 321. By means of the first limiting groove 321 and slidably clamping one end of the mounting plate 32 inside the first limiting groove 321, the mounting plate 32 is limited, that is, the mounting plate 32 can move more stably when driven by the electric push rod 31 to move up and down.

[0024] Two groups of mirror-symmetrically distributed moving grooves 41 are provided on the outer surface of the limiting roller 4. The middle parts of the two limiting plates 43 are slidably clamped inside the moving grooves 41. By providing the moving grooves 41 and slidably clamping the middle parts of the limiting plates 43 inside the moving grooves 41, the limiting plates 43 are limited and can also move by the rotation of the screw rod 42 to limit the pole piece.

[0025] A handle 44 is fixedly installed at one end of the screw rod 42 passing through the limiting roller 4. By providing the handle 44 and rotating the handle 44, the screw rod 42 is driven to rotate, and then the two limiting plates 43 threadedly installed on the outer surface of the screw rod 42 move relatively or away from each other, so as to limit the pole piece passing through the limiting roller 4.

[0026] Working principle: In actual use, the roller wound with the pole piece is installed in the middle of one of the mounting shafts 21. One end of the pole piece passes through between the first rolling shaft 34 and the second rolling shaft 35 and is then installed in the middle of the mounting shaft 21 at the other end of the fixed plate 2. Driven by the servo motor and transmitted by the transmission belt, the two mounting shafts 21 cooperate with each other. One end releases the pole piece outward, and the mounting shaft 21 at the other end winds the pole piece that has completed rolling. While the mounting shafts 21 rotate in cooperation with each other, the first motor 11 is started. Driven by the first motor 11, the rotating shaft 12 is driven to rotate, that is, the first bevel gear 13 and the second bevel gear 14 are driven to rotate. The first bevel gear 13 and the second bevel gear 14 are arranged oppositely, that is, the third bevel gear 341 and the fourth bevel gear 351 are driven to rotate in opposite directions, so that the first rolling shaft 34 and the second rolling shaft 35 rotate relatively, thereby pressing the pole piece. When it is necessary to adjust the distance between the first rolling shaft 34 and the second rolling shaft 35, the electric push rod 31 is started. Driven by the electric push rod 31, the mounting plate 32 is driven to move downward, thereby driving the first rolling shaft 34, the second bevel gear 14 and the third bevel gear 341 to move simultaneously, so as to adjust the distance between the first rolling shaft 34 and the second rolling shaft 35, and thus the pole piece to be pressed can be extruded into the required thickness;

[0027] By rotating the handle 44, the screw rod 42 is driven to rotate. Since the outer surface of the screw rod 42 is provided with a positive and negative thread, the two limit plates 43 threadedly mounted on the outer surface of the screw rod 42 are driven to move relatively or away from each other, so as to limit the pole piece passing through the limit roller 4.

[0028] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and its equivalent technologies, the present invention is also intended to include these modifications and variations.
