[0002] Multi-layer composite flooring is favored by the European and American markets for its beautiful decorative effect and very convenient paving construction. In recent years, it has become a new star in the field of floor decoration. After the multi-layer composite flooring adopts the hot pressing process of stacking different functional sheets, due to the large difference in thermal expansion coefficients between different sheets, internal stress will be generated after hot pressing and cooling, causing the floor to deform. Therefore, heat treatment must be performed after hot pressing. The current heat treatment process has heating and water cooling processes. The current heat treatment technology generally uses electric heating, but electric heating has the problem of overheating or uneven heating, and there is also the phenomenon of rapid cooling after heating and generating new stress. After water cooling, the floor needs to be dried. At present, air drying equipment or drying equipment is used after the water cooling process to remove the attached water on the surface of the floor, but the use of a single air drying equipment often cannot remove all the water, and installing both will increase energy consumption.
[0003] Therefore, the above problems are issues that should be considered and solved in the process of floor production. Summary of the invention
