Problems solved by technology

[0005] Secondary impregnation and drying machinery has particularly strict requirements on the environment, such as the temperature or humidity in the environment. Due to the drastic changes in the external temperature, the yield of the product will be greatly reduced, and the quality cannot be guaranteed; at the same time, the service life of the machine will be seriously reduced. In addition, most of the heat generated by the heating and drying device in the secondary impregnation and drying machine is directly discharged into the air, resulting in energy loss. At the same time, it also increases the temperature of the secondary impregnation and drying machine itself. changes, which are extremely detrimental to the production process

Abstract

The invention discloses an adhesive film paper dipping drying method which comprises the following steps: fully dipping in a first dipping mechanism; heating and drying in a first drying mechanism; fully secondarily dipping in a second dipping mechanism; heating and drying in a second drying mechanism; cooling to room temperature in a cooling mechanism; and sending the cooled adhesive film paper into a stacking mechanism for stacking storage. The first drying mechanism is provided with a dipping agent recovery device, part of a dipping agent carried out from the first dipping mechanism is recovered, and returned to the first dipping mechanism, system temperature fluctuation can be improved by the device, and the production process tends to be a stable environment.

Description

technical field [0001] The invention belongs to the technical field of dipping and drying machines, and in particular relates to a method for dipping and drying filmed paper. Background technique [0002] At present, impregnation machinery has been more and more widely used in people's daily life, especially the secondary impregnation and drying production line is mainly used for furniture boards, melamine veneer paper, decorative surface sheets for reinforced composite floors, wear-resistant paper, Plywood kraft paper, decorative paper; production of kraft paper for cement templates and production of alkali-free glass fiber cloth, cotton cloth, wood pulp paper, and copper foil. [0003] Patent application number 201120414760.9 discloses a double-cone rotary vacuum dryer, which can realize the function of supplying liquid materials to the barrel of the double-cone rotary vacuum dryer under vacuum and rotation. The double-cone rotary vacuum dryer includes a cylinder, a hollo...
