[0003] Currently, the existing methods for coating lithium-ion battery electrodes mainly include comma roll transfer coating and slot extrusion coating. During the coating process, the coating roll contacts the coating slurry every time it rotates one week, and the coating slurry is coated onto the base fabric through the coating roll. However, there will be residual coating slurry on each coating roll. If the residual coating slurry is not processed in a timely manner, the thickness of each coating cannot be guaranteed, affecting the coating accuracy.

[0004] Therefore, we propose a high-precision pressure-sensitive coating machine. Content of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present utility model.

[0031] Embodiment: A high-precision pressure-sensitive coater, as Figure 1 and Figure 2 shown, includes an equipment frame 1. There is a drying chamber 2 on the equipment frame 1. A connection groove 3 runs through the equipment frame 1. Inside the connection groove 3, symmetrically arranged left and right connecting plates 4 are fixedly installed. A winding shaft 5 is rotatably installed between the two groups of connecting plates 4. An inlet / outlet opening communicating with the inside of the connection groove 3 runs through the top surface of the equipment frame 1. The drying chamber 2 also has an inlet / outlet opening running through it. Guide columns 14 are rotatably installed in the inlet / outlet openings;

[0032] As Figure 1 and Figure 3 shown, multiple support frames are provided on the top surface of the equipment frame 1. A guide roller 6 and a first coating roller 7 are respectively rotatably installed in the multiple support frames. The outer surfaces of the guide roller 6 and the first coating roller 7 are close to each other. The distance between the guide roller 6 and the first coating roller 7 is the same as the thickness of the base fabric. During use, the base fabric wound on the winding shaft 5 extends vertically upward through the inlet / outlet opening to the upper end of the top surface of the equipment frame 1. The upward-extending base fabric passes through the guide roller 6 for pressure-sensitive coating and is finally exported outward through the drying chamber 2. The coating on the base fabric is cured by the high temperature in the drying chamber 2;

[0033] As Figure 1 and Figure 3 shown, symmetrically arranged left and right extension arms 9 are fixedly installed on the inner side surface of the drying chamber 2. A second coating roller 10 is rotatably installed between the two groups of extension arms 9. The outer surface of the second coating roller 10 is in contact with the outer surface of the first coating roller 7;

[0034] As Figure 1 and Figure 4 shown, a support plate 11 is fixedly spliced on the side of the extension arm 9 away from the drying chamber 2. A paint cylinder 12 is fixedly installed between the two symmetrically arranged support plates 11. A paint discharge opening 13 is provided at the lower end of the paint cylinder 12. The paint discharge openings 13 are distributed at the place where the first coating roller 7 and the second coating roller 10 are close to and in contact with each other;

[0035] Among them, the rotation directions of the guide roller 6, the first coating roller 7, and the second coating roller 10 are all the same. During use, the paint cylinder 12 discharges the paint downward through the paint discharge opening 13. The paint is distributed between the first coating roller 7 and the second coating roller 10. The first coating roller 7 and the second coating roller 10 rotate simultaneously to evenly coat the paint on the base fabric passing through the guide roller 6. After the base fabric is coated, it is dried by the drying chamber 2 and exported outward;

[0036] As Figure 1 and Figure 5As shown in the figure, a cleaning roller assembly 8 is fixedly installed on the top surface of the equipment rack 1 through a support frame. The cleaning roller assembly 8 is distributed on the outer side surface of the first coating roller 7 and is in contact with the first coating roller 7. The cleaning roller assembly 8 includes a metal column core 801. The metal column core 801 is fixedly installed on the support frame through a mounting shaft 802. A plurality of groups of cleaning cotton blocks 803 are provided on the outer surface of the metal column core 801. A magnetic attraction plate 804 is fixedly installed on the inner side surface of the cleaning cotton block 803. The cleaning cotton block 803 is adsorbed and fixed on the outer surface of the metal column core 801 through the magnetic attraction plate 804. The plurality of groups of cleaning cotton blocks 803 are annularly arrayed on the outer surface of the metal column core 801 with the center of the metal column core 801 as the center. The plurality of groups of cleaning cotton blocks 803 completely cover the outer surface of the metal column core 801. A handwheel for controlling the rotation of the cleaning roller assembly 8 is provided on the support frame corresponding to the cleaning roller assembly 8. During use, the guide roller 6, the first coating roller 7, and the second coating roller 10 rotate together and perform a coating operation. When the first coating roller 7 rotates, it contacts the cleaning roller assembly 8. And when the first coating roller 7 rotates one circle, the outer surface of the first coating roller 7 will contact the cleaning cotton block 803 every time. The residual coating on the outer surface of the first coating roller 7 is adsorbed and cleaned by the cleaning cotton block 803. After a group of cleaning cotton blocks 803 is contaminated, the rotation of the cleaning roller assembly 8 is controlled by rotating the handwheel, so as to replace a group of cleaning cotton blocks 803 to contact the first coating roller 7, which is convenient for continuously cleaning the outer surface of the first coating roller 7, and enables the first coating roller 7 and the second coating roller 10 to evenly coat the coating on the base cloth passing through the guide roller 6 during rotation.

[0037] The working principle of the present utility model:

[0038] The paint cylinder 12 discharges the paint downward through the paint feeding port 13. The paint is distributed between the first coating roller 7 and the second coating roller 10. The first coating roller 7 and the second coating roller 10 rotate simultaneously to evenly coat the paint on the base cloth passing through the guide roller 6. After the base cloth is coated, it is dried in the drying chamber 2 and then exported outward.

[0039] During use, the guide roller 6, the first coating roller 7, and the second coating roller 10 rotate together and perform a coating operation. When the first coating roller 7 rotates, it contacts the cleaning roller assembly 8. And when the first coating roller 7 rotates one circle, the outer surface of the first coating roller 7 will contact the cleaning cotton block 803 every time. The residual coating on the outer surface of the first coating roller 7 is adsorbed and cleaned by the cleaning cotton block 803. After a group of cleaning cotton blocks 803 is contaminated, the rotation of the cleaning roller assembly 8 is controlled by rotating the handwheel, so as to replace a group of cleaning cotton blocks 803 to contact the first coating roller 7, which is convenient for continuously cleaning the outer surface of the first coating roller 7, and enables the first coating roller 7 and the second coating roller 10 to evenly coat the coating on the base cloth passing through the guide roller 6 during rotation.
