[0020] Working principle: When the impregnation device for producing decorative paper is in operation, an appropriate amount of impregnation liquid is first injected into the impregnation tank 1. The raw material paper enters the impregnation tank 1 from the feed roller 301. The feed motor 201 is started to drive the feed roller 301 to rotate, providing power for the conveying of the raw material paper. After entering the impregnation tank 1, the raw paper is immersed in the impregnation liquid under the guidance of the conveying roller 3. The conveying roller motor 2 is started to drive the conveying roller 3 to rotate, ensuring that the raw paper can fully contact the impregnation liquid and complete the impregnation process. The discharge motor 202 is started to provide power for the rotation of the discharge roller 302, and the paper is output from the impregnation tank 1 under the action of the discharge roller 302. Because the bottom of the immersion tank 1 is higher at the back and lower at the front, the debris generated during the immersion process will move with the immersion liquid toward the outlet on the bottom of the immersion tank 1, and thus enter the drain outlet 4 and the drain pipe 5. The first motor 10 starts and drives the turntable 907 to rotate. The rotation of the turntable 907 drives the turntable connecting block 906 to rotate. The rotation of the turntable connecting block 906 drives the limiting groove 905 to move up and down. The up and down movement of the limiting groove 905 drives the sliding rod connecting block 904 to move up and down, thereby driving the sliding rod 901 to slide up and down in the sliding rod groove 903, and thus causing the piston 902 to reciprocate in the piston box 9. When piston 902 moves upward, a negative pressure is formed in drain pipe 5, the front piston door 503 opens and the rear piston door 504 closes, and the impregnation liquid containing debris enters drain pipe 5 from drain port 4; when piston 902 moves downward, the front piston door 503 closes and the rear piston door 504 opens, and the impregnation liquid is forced into filter pipe 6; in filter pipe 6, filter screen 604 filters the impregnation liquid to remove debris, and the filtered impregnation liquid returns to impregnation tank 1 through water filling pipe 7 and water filling port 8, realizing the recycling of impregnation liquid. The threaded connection between connecting fitting 602 and threaded sleeve 603 facilitates the disassembly and replacement of filter pipe 6 to ensure filtration effect. The turntable 907 is driven to rotate by motor 10. Through the structural transmission of turntable connecting block 906, limiting groove 905 and sliding rod connecting block 904, piston 902 reciprocates in piston box 9, causing impregnation liquid with debris to enter drain pipe 5. Then it is filtered through filter screen 604 in filter pipe 6. The filtered impregnation liquid flows back to impregnation tank 1, which can continuously remove debris in impregnation liquid, reduce the amount of debris adhering to the paper surface, and thus improve the surface quality of paper after impregnation.
[0021] The threaded connection between the connecting fitting 602 and the threaded sleeve 603 facilitates the disassembly and replacement of the filter tube 6, ensuring the continuity of the filtration effect and allowing the impregnating liquid to remain clean for a long time through circulation filtration.
