[0029] Example 2, refer to Figure 3 , Figure 4 , Figure 5 and Figure 6This embodiment solves the problem that in existing sodium-ion battery electrode production pressing devices, when pressing coated and heated battery electrodes, the coating on the surface of the electrode tends to adhere to the upper pressure roller, causing dents in the subsequently pressed electrodes and affecting the quality of electrode production. This new sodium-ion battery electrode production pressing device further includes a pressing mechanism 4 comprising a lower pressure roller 401 rotatably mounted on the bottom left side of a fixed plate 3, an upper pressure roller 402 rotatably mounted on the upper left side of the fixed plate 3, and a mounting plate 403 fixedly connected to the left rear end of the rear fixed plate 3. The upper surface of the mounting plate 403... A first motor 404 is mounted on the surface. The power output end of the first motor 404 is connected to the lower pressure roller 401. A pulley 405 is fixedly connected to the middle of the rear ends of the lower pressure roller 401 and the upper pressure roller 402. A belt 406 is sleeved on the outer surface of the pulley 405. The scraping mechanism 5 includes an arc-shaped scraper 501 mounted on the fixed plate 3.

The blocking mechanism 6 includes a T-shaped plate 601 installed on the left side of the upper surface of the fixed plate 3. An curved plate 602 is installed at the upper end of the T-shaped plate 601. Fixing bolts 603 are inserted on the left and right sides of the T-shaped plate 601.

The cooling roller mechanism 7 includes a cooling rod 701 rotatably mounted on the fixed plate 3, a cooling roller 702 fixedly connected to the outer surface of the cooling rod 701, a spiral air guide vane 703 installed at the rear end of the inner cavity of the cooling rod 701, a second motor 704 installed in the middle of the front end of the front fixed plate 3, a sprocket 705 installed at the power output end of the second motor 704 and the front end of the cooling rod 701, a chain 706 sleeved on the outer surface of the sprocket 705, a ventilation groove opened in the inner cavity of the cooling roller 702, and the cooling roller 702 is made of alloy steel.
[0030] Working principle: When this device is in use, after connecting the dried electrode sheet to the take-up roller 11, the third motor 10 is turned on to facilitate the winding of the electrode sheet. When the electrode sheet passes through the pressing mechanism 4, it is pressed by the lower pressing roller 401 and the upper pressing roller 402. Simultaneously with passing through the lower pressing roller 401 and the upper pressing roller 402, the first motor 404 is turned on, which drives the lower pressing roller 401 to rotate. This rotation is achieved through the pulley 405 and the belt 406. The design facilitates the synchronous rotation of the lower pressure roller 401 and the upper pressure roller 402, enabling efficient conveying and pressing of the extruded material. Simultaneously, the arc-shaped scraper 501 removes coatings and impurities adhering to the surface of the upper pressure roller 402, preventing them from causing dents in the subsequently pressed electrode sheets. The inclusion of a collection trough 503 and a storage drawer 504 facilitates the collection of scraped coatings and impurities, preventing them from falling onto the electrode sheet surface and affecting subsequent material handling. The system incorporates an arc-shaped plate 602 and a baffle 604 to shield the surface of the upper pressure roller 402 from coatings and impurities that may scrape against it. This prevents the coatings and impurities from bouncing off and falling onto the electrode surface, causing them to be squeezed during winding and resulting in electrode breakage, thus affecting the quality of the electrode production. The system also includes a T-shaped plate 601 and fixing bolts 603 to facilitate the disassembly and installation of the arc-shaped plate 602. When the electrode passes through the cooling roller 702, it is activated by a second motor 70... 4. The sprocket 705 is driven to rotate, causing the multiple sprockets 705 connected by the chain 706 to rotate synchronously. This causes the spiral air guide vanes 703 inside the cooling rod 701 to rotate, which can guide external air into the inner cavity of the cooling roller 702 for continuous cooling and ensure the effectiveness of the cooling of this device. The cooling roller 702 is made of alloy steel, which is convenient for cooling the dried and pressed electrode sheets. After the electrode sheets are cooled, they can be wound up by the winding roller 11.
