In the production process of rubber and plastic products, the rubber sheet cooling line is a key equipment connecting the pre-forming and post-processing stages. It undertakes core tasks such as cooling, shaping, and winding of rubber sheets, directly affecting the dimensional accuracy, physical properties, and production efficiency of the final products. Its operational stability and cooling effect play a decisive role in the quality control of rubber and plastic products.

The working principle of the rubber sheet cooling line centers on "precision cooling + stable conveying". High-temperature rubber sheets formed by pre-processes such as open mixing and calendering are smoothly fed into the cooling area by the conveying mechanism. Gradient cooling is achieved through multi-stage cooling rolls, cooling water tanks, or air cooling devices—first quickly reducing the surface temperature of the rubber sheet, then gradually conducting it to the interior, avoiding cracking and deformation of the rubber sheet due to rapid cooling, and eliminating internal stress at the same time. During the cooling process, the tension adjustment system equipped with the equipment can real-time control the conveying speed and tension of the rubber sheet, ensuring the sheet is flat and wrinkle-free, laying a solid foundation for subsequent processes such as cutting and vulcanization.
