Description
The present invention relates to a high-speed lamination apparatus, and more particularly, to a lamination apparatus comprising a functional film used for a display, a fuel cell, various packaging materials, and the like. The film is heated by a preheating roll, The present invention relates to a high-speed laminating apparatus capable of preventing adhesion of an adhesive applied on a film to a film by improving the adhesive performance and laminating the film at a high speed.
Recently, functional films have been widely used in various fields such as displays, fuel cells, and various packaging materials.
The above-mentioned functional film is produced by a lamination apparatus in which two or three films are joined together by a roll-to-roll method.
1 schematically shows a process for producing a functional film using the "dry lamination" method.
The conventional dry lamination apparatus includes a

The above-mentioned "dry lamination method" is a method in which the structure is simple and the production speed is higher than that of the " extrusion lamination "method in which resin is supplied by resin extruder, Has the advantage of being fast.
In addition, the dry lamination method can be applied to metal foils such as copper and zinc as well as polymer films and aluminum foils because the material and adhesive of the film can be freely selected.
In the dry lamination method described above, since the first film F1 and the second film F2 are adhered to each other under heat and pressure, the heat transferred to the adhesive agent B and the pressing force exert the adhesion performance of the film It is the main variable to decide.
Accordingly, the joining
However, when the film is laminated at a high speed in the above conventional dry lamination apparatus, there is a problem that it is difficult to transfer sufficient heat to the adhesive because the film passes through the
That is, there is a problem that it is difficult to sufficiently transfer the heat of the
In order to solve the above-mentioned problem, the roll rotation speed of the
Therefore, it is pointed out that a conventional dry lamination apparatus is difficult to form a high-quality film at a high speed.
It is an object of the present invention to provide a high-speed lamination apparatus capable of producing a high quality laminated film at high speed.
Another object of the present invention is to heat the film by a preheating roll and then feed it to the joint so that the adhesive maintains optimum tackiness when the film is laminated.
It is still another object of the present invention to prevent a decrease in adhesive performance due to a decrease in the temperature of an adhesive applied to one side of a film.
It is a further object of the present invention to improve the bonding performance by allowing the film to be laminated at a constant temperature at all times.
In order to achieve the above-mentioned object, the present invention provides a film forming apparatus comprising: a first supply winder for supplying a first film; a coating part for coating an adhesive on one surface of the first film supplied from the first supply winder; A drying chamber for drying the coated adhesive in the coating portion by supplying or heating, a second feeder for feeding a second film, and a second film feeder for feeding the first film and the second feeder from the drying chamber A film lamination apparatus comprising a joining portion joining a first film and a second film, and a winding winder for winding a film laminated on the joining portion, wherein a first film passed through the drying chamber is heated And the preheating roll is further provided.
Further, the preheating roll is heated by a high temperature water vapor or a heating medium of oil.
The preheating roll is characterized in that an induction coil is inserted in the preheating roll and heated by an induction heating method using an alternating current.
In addition, the joining portion is provided inside a constant temperature chamber capable of maintaining a constant temperature.
In addition, the constant temperature chamber is provided with a thermostat.
The upper roll provided in the constant temperature chamber may be a heating roll.
Also, hot air supplied to the drying chamber is simultaneously supplied to the inside of the constant temperature chamber.
According to the present invention, the film is heated by the preheating roll and then supplied to the joint portion, so that there is an effect that the adhesive maintains optimum adhesiveness when the film is laminated.
As a result, a high-quality film can be produced at a high speed in a dry lamination apparatus, thereby improving productivity.
Further, there is an effect that the temperature of the adhesive applied to one side of the film is lowered, and the adhesion performance is prevented from being lowered.
Further, by allowing the film to always be laminated at a constant temperature, there is an effect that the bonding performance of the film can be improved.
