[0026] Reference Figure 1-Figure 6 A sodium ion battery pole piece pressing device comprises a fixing frame 1 and a pressing roller 2, wherein the pressing roller 2 is connected to a driving mechanism for driving the pressing roller 2 to rotate, and the sodium ion battery pole piece passes between two pressing rollers 2 and is squeezed into a suitable thickness under the pressure of the two pressing rollers 2;

[0027] Specifically, it also includes an interval adjustment mechanism 3 for adjusting the interval between the two sheet pressing rollers 2, the interval adjustment mechanism 3 includes an adjustment bracket, one sheet pressing roller 2 is rotatably mounted on the adjustment bracket, and the other sheet pressing roller 2 is rotatably mounted on an adjustment slider 302, the adjustment slider 302 is threadedly connected to an adjustment screw 301, the adjustment screw 301 penetrates the adjustment bracket, and an adjustment handle is installed on the top of the adjustment screw 301; the adjustment screw 301 is rotated to drive the adjustment slider 302 to slide up and down, thereby adjusting the interval between the upper and lower sheet pressing rollers 2, and adjusting the interval according to demand, so as to extrude the sodium ion battery pole piece into a suitable thickness;

[0028] In a further embodiment, a position adjustment mechanism 13 is installed on the fixed frame 1, and the position adjustment mechanism 13 is used to drive the oiling sponge 4 and the degreasing sponge group 5 to move axially along the sheeting roller 2. The oiling sponge 4 and the degreasing sponge group 5 are both installed on the angle adjustment frame 6. The angle adjustment frame 6 is connected to the angle adjustment mechanism 7 for adjusting its angle. The angle adjustment mechanism 7 drives the angle adjustment frame 6 to rotate so that it has at least two states, wherein the two states are respectively an oiling state and a degreasing state. In the oiling state, the oiling sponge 4 fits the outer surface of the sheeting roller 2, and oil is applied to the outer surface of the sheeting roller 2 under the drive of the position adjustment mechanism 13 to form a thin oil layer to prevent the sheeting roller 2 from directly contacting the air outside and preventing it from oxidizing. In the degreasing state, the degreasing sponge group 5 fits the outer surface of the sheeting roller 2, and the thin oil layer on the outer side of the sheeting roller 2 is removed under the drive of the position adjustment mechanism 13.

[0029] Specifically, the degreasing sponge group 5 includes a main sponge 501 and two secondary sponges 502. The main sponge 501 is located between the two secondary sponges 502. The main sponge 501 and the secondary sponge 502 are separated by a partition. The main sponge 501 and the secondary sponge 502 are both installed on a bracket. A main pipe 14 and two secondary pipes 15 are inserted in the bracket. The outlet of the main pipe 14 is aligned with the main sponge 501, and the outlet of the secondary pipe 15 is aligned with the secondary sponge 502.

Therefore, a cleaning box 8 is installed on the fixing frame 1. The cleaning box 8 is used to remove the oil adhered to the degreasing sponge group 5. The degreasing sponge group 5 completely enters the cleaning box 8 and enters the cleaning state. In the cleaning state, the control valves in the main pipe 14 and the secondary pipe 15 are opened, and anhydrous ether infiltrates the main sponge 501 and the secondary sponge 502;

[0031] Specifically, a cleaning block 10 is installed in the cleaning box 8. In the cleaning state, the cleaning block 10 is fitted with the outer surfaces of the main sponge 501 and the secondary sponge 502. A number of grooves are provided on the cleaning block 10 for the flow of anhydrous ether and oil. The cleaning block 10 is connected to a vibration mechanism 11 for driving the vibration thereof. The vibration mechanism 11 drives the cleaning block 10 to shake back and forth, and the oil adhered to the main sponge 501 and the secondary sponge 502 can be removed with the flowing anhydrous ether. After cleaning for a period of time, the control valves in the main pipe 14 and the secondary pipe 15 can be closed, and the vibration mechanism 11 drives the cleaning block 10 to continue to vibrate, so that the main sponge 501 and the secondary sponge 502 can be dried quickly.
