[0048] Working principle: During use, the jacquard fabric is passed through the gap between the bottom shell 1 and the top shell 2. Then, the gap between the top shell 2 and the bottom shell 1 is adjusted so that the guide rollers 11 of the top shell 2 and the bottom shell 1 squeeze the jacquard fabric. After that, the jacquard fabric is pulled by an external winding device. At the same time, the pressurized pump 6 is connected to the water supply pipeline. The drain end of the pressurized pump 6 is connected to two spray pipes 17. This can pull the jacquard fabric. At the same time, the drive motor 4 is started. The drive motor 4 drives the brush roller 3 to clean the surface of the jacquard fabric. After cleaning, the jacquard fabric passes through the gap between the two guide rollers 11. The squeezing of the two guide pipes can squeeze out some of the moisture in the jacquard fabric, avoiding excessive moisture that would affect the subsequent drying efficiency.
