Description

TECHNICAL FIELD OF THE INVENTION A manufacturing method of a thin film processed with a mechanical pattern and a device therefor {PREPARING METHOD OF THIN FILM PROCESSED WITH MECHANICAL PATTERN AND APPARATUS THEREOF}

The present invention relates to a method for producing a mechanically patterned thin film, and a device thereof, and more particularly, when a metal material such as a synthetic resin such as a thermoplastic resin or a thermosetting resin, or a metal material such as aluminum is extruded into a film or sheet, By passing a film or sheet extruded from a die for dynaflation, through a perforated and / or embossed mold roll heated to a constant temperature by a heater, a film and sheet capable of forming and / or perforating a certain pattern on the film or sheet can be produced. It is possible to perform the punching molding process and the embossing molding process at the same time in one mold roll in the production of perforation and / or embossing film or sheet, and by cooling directly in a straight line after high temperature molding, it has a constant pattern and fine molding Perforated and / or embossed film with possible and uniform patterns The method and apparatus for manufacturing a thin layer film or sheet having a mechanical pattern capable of producing a sheet and of course producing a film or sheet extruded from a die on the same line, which enables continuous mass production and improve productivity. It is about.

In general, a film or sheet that is embossed with a thermoplastic resin such as polyethylene resin, polyolefin resin, or polyvinyl chloride is embossed with a predetermined shape, and thus the reflectance is increased from light, and the pattern of embossing is different. The contact area with the object is small, and the film and sheet made of thermosetting resin such as unsaturated polyester resin are imprinted with a certain shape on the surface part to improve the appearance or prevent the surface part from slipping and friction with other objects. However, even when the surface is worn and scratched when contacted, the light reflectance is high, which can compensate for the surface flaw and make the exterior of the surface look beautiful. Patterned patterns allow embossing to form There. In addition, in case of a film or sheet manufactured by fine perforation, the flow of gas or liquid is made very smoothly and when the embossing pattern is imprinted therein, the flow of gas or liquid is made more smoothly by the pattern and perforated part of the embossing. Therefore, when laminating rubbery sheet products or when separating and stacking materials that are easily adhered or fused, the use of perforated embossing films facilitates the circulation of air and makes it easier to use other materials. It can solve the problem of adhesion, fusion, and adhesion by reducing the contact area of even more. When using perforated film as food waste bag, it removes moisture of food waste and facilitates the inflow of oxygen during landfill. Not only can it accelerate the rate of decay, but also degradable bacterium Facilitating the inflow and activity of ria results in reducing environmental harm. In addition, when the heat-curable synthetic resin sheet or thin metal plate or aluminum plate is made of finely perforated embossed sheet and used as a sound absorbing plate to remove noise, the sound absorption effect can be enhanced than that of a simple perforated sheet or metal plate. .

In general, in the method of forming embossing on the thermoplastic resin or thermosetting resin, conventionally, by performing a separate process of passing the product rolled up the film or sheet extruded from the die and passing the high-temperature die roll embossed again. The film or sheet is pressed between the upper plate and the lower plate by embossing or by pressing the press to allow the upper and lower plates to face each other with respect to the film or sheet cut into a predetermined shape such as a substantially square plate shape. . At this time, the press upper plate and the lower plate are provided with a heater, and the film heats the press upper plate and the lower plate and passes between the press upper plate and the lower plate in a pattern imprinted on the mold by the pressing force of the press and the heat of the heater. The embossing is molded, and the film or sheet on which the embossing is molded is cooled while passing through a cooling process to be formed into an embossing film or sheet.

On the other hand, in the conventional method of perforating a film or sheet such as a thermoplastic resin or a thermosetting resin, a film or sheet of a certain size is put into a press as described above, and then a film or sheet is Although perforating the sheet may be performed, such a method may reduce the work efficiency and limit the size and amount of the film or sheet to be processed, as the movement of the film or sheet is performed by a worker. Since each film or sheet is fused to each other by heat by punching in a large amount in the same press, there is a problem that is not suitable to continuously produce a large amount of films or sheets that are precisely punched and stamped.

Therefore, as described above, during the embossing and / or manufacture of the perforated film or sheet, the entire process from the extrusion of the resin to the manufacture of the molded film has to be introduced into different production processes instead of being serially arranged on the same line. Of course, it is difficult to continuously produce a large amount of embossing and / or perforated film or sheet, and a problem arises in that the films or sheets are fused together by perforating a large amount of film or sheet by heat during perforation of the film or sheet. And / or problems such as uneven or inaccurate shape of the perforated film or sheet. In particular, when manufacturing the embossed stamped perforated film or sheet, the perforation work and the embossing molding operation is performed separately, there was a disadvantage that it is difficult to manufacture a film or sheet of fine, accurate and uniform shape.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and the first object of the present invention is to continuously form mechanical patterns in the same production line in a continuous production method of a continuous thin film. By uniformly processing a fine pattern thereby to provide a continuous manufacturing method of a thin film processed mechanical pattern that can improve the productivity and productivity by continuous mass production.

It is a second object of the present invention to provide a method for producing a thin film that is more useful in terms of environment because it is possible to distribute moisture or air by efficient perforation of the thin film.

A third object of the present invention is to provide a method for producing a thin film that can improve adhesion, fusion, and adhesion during lamination.

It is a fourth object of the present invention to provide an apparatus for producing a thin film, in which mechanical patterns are processed to smoothly perform the first to fourth objects described above.
