[0002] In the modern printing and dyeing textile industry, fabrics that have just gone through the printing and dyeing process contain a lot of water, which also carries chemicals such as dyes and auxiliaries. In order to effectively separate this water, dehydration technology is usually used, and common methods include centrifugal dehydration and extrusion dehydration. However, the centrifugal process may cause wrinkles or damage to the fabric, so extrusion dehydration has gradually become a more popular choice. However, traditional extrusion dehydration equipment can only provide a fixed pressure level, which has limitations when processing fabrics of different thicknesses and moisture contents. In view of this, it is particularly important to develop an intelligent dehydration system that can automatically adjust the pressure according to the fabric characteristics and moisture content.

[0003] In an existing dehydration device, a support plate with a plurality of through holes is arranged under the cloth. This arrangement makes it impossible for the through holes to be subjected to force during extrusion, thus greatly affecting the dehydration effect. Summary of the invention
