Abstract

The invention discloses a dehumidification drying device used in EVA photovoltaic encapsulation adhesive film production, and relates to the technical field of EVA adhesive film production equipment. The dehumidification drying device comprises a drying dehumidification box and an EVA adhesive film penetrating through the drying dehumidification box. The drying dehumidification box comprises a film inlet formed in the top face, a film outlet formed in the side wall, a roller set horizontally arranged in an inner cavity and a dehumidification mechanism arranged on the side wall. The dehumidification drying device disclosed by the invention is provided with the drying dehumidification box and used for providing a relatively-sealed space so that the EVA adhesive film and the roller set can be dried and dehumidified, and the phenomenon that roller sticking of the EVA adhesive film happens due to the fact that surface humidity of the roller set is excessively high is prevented. The drying dehumidification efficiency and the degree of automation are high, product quality is improved, raw material losses are reduced, and manpower is saved.

Description

technical field [0001] The invention belongs to the technical field of EVA adhesive film production equipment, and in particular relates to a dehumidification and drying device in the production of EVA photovoltaic packaging adhesive film. Background technique [0002] EVA (polyethylene-vinyl acetate) film is currently the most commonly used material in solar packaging technology, and is generally produced by extrusion-calendering or extrusion-casting. The production process includes melt blending, extrusion, calendering, traction and coiling, etc. Its physical and mechanical properties mainly include transparency, tensile strength, aging resistance, shrinkage, etc. If the film sticks to the roll surface during the calendering process, the shrinkage rate of the stretched film will inevitably increase, and its surface quality will also be affected. Therefore, the process requires that the roller temperature be lowered to cool the film to meet the production requirements. Th...
