[0002] With the continuous improvement of economic level, solvent-free composite machines have been widely used. Solvent-free composite machines are equipment that use solvent-free adhesives to composite two or more substrates together. In the composite process of single-component solvent-free adhesives, single-component polyurethane adhesives are cured by reacting with hydroxyl groups provided by water molecules in the air. The air humidity at the production site is required to be greater than 60%, otherwise poor curing is likely to occur. Therefore, it is necessary to humidify the solvent-free adhesive to ensure sufficient moisture.

[0003] At present, solvent-free laminating machines generally have a steam humidifier installed on the machine body. Steam is used for humidification during the lamination process of the solvent-free substrate. After humidification, the steam diffuses and is not easy to recycle and reuse, resulting in a waste of water resources. Summary of the Invention

[0025] Further as Figure 3 As shown, it is worth noting that the interior of the condensing frame 2 is hollow, and the water passage cavity of the condensing frame 2 is connected to the circulating water tank 3.

[0026] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth noting that one end of the water outlet pipe 4 is fixed to the water outlet end of the circulating water pump 5 , and the other end of the water outlet pipe 4 is fixed to a side surface of the condensing frame 2 .

[0027] Further as Figure 4 As shown, it is worth noting that the water inlet end of the circulating water pump 5 is fixed on the lower end surface of the circulating water tank 3, the circulating water tank 3 is connected to the water inlet pipe 6, and the water outlet pipe 4 is connected to the condensation frame 2.

[0028] Further as Figure 1 As shown, it is worth noting that the humidification water tank 9 is fixed on the inner top wall of the condensation frame 2 , and a water storage chamber 10 is provided inside the humidification water tank 9 .
