Description

Manufacturing method of hollow glass with built-in adjustable film and transmission structure

The invention relates to a manufacturing method and a transmission structure for installing a tunable film in a hollow glass to improve the energy-saving effect of the hollow glass and increase the dimming function.

Prior art prior to the present invention

Insulating glass has been widely used due to its unique thermal and sound insulation properties. In order to further improve the energy-saving function of insulating glass on the existing basis, various methods have been adopted, such as using selectively coated glass to make insulating glass, and adding one or more layers of film to the interior of the insulating glass to block the interior. Gas flow heat transfer and so on. Although these improvement methods have certain effects, for climate change throughout the year, these static structures are difficult to meet the different energy-saving requirements of insulating glass under various climate conditions. On the other hand, because glass cannot be dimmed, curtains are usually installed for dimming after the glass is installed. Although there are many designs and products of hollow glass with jalousie, the structure of the jalousie is bulky and complicated, and A wide space is required for the turning of curtain blades, and it is difficult to install it in hollow glass, which has a wide internal gap of less than 12mm.

In order to simultaneously achieve the dual objectives of improving the energy-saving performance of the insulating glass and increasing the dimming function,

— Designs of hollow glass with built-in adjustable roller blinds, such as the PCT patent application, entitled "INSULATING GLASS PANE COMPRISING AN INTEGRATED ROLLER BLIND DEVICE)", and the application number is WO01 / 53647A1. U.S. Patent, entitled "INSULATING GLASS ARRANGEMENT WITH A FOIL SHADE)), Patent No. US6,557,613B2. These designs have certain characteristics, but the shortcomings are also obvious, such as the large size and the complicated transmission mechanism. It will be more difficult to use it inside hollow glass with an internal gap of less than 12mm.

Object of the invention

The task of the present invention is to propose a method for manufacturing a kind of built-in adjustable thin-film hollow glass and a transmission structure. The film and the transmission mechanism are installed in the hollow glass with an internal gap of 12 mm or less. The pieces do not touch the transmission to adjust and control the film movement in the insulating glass, so that the insulating glass has the dual adjustable function of adjusting heat insulation performance and light.

Technical solution adopted by the present invention

The manufacturing method of the built-in adjustable thin-film insulating glass of the present invention is as follows: Adopt anti-aging thin film material with a thickness of less than 0.05tnm, such as polyester film, polycarbonate film or other organic film.

1

Confirm this The substrate can be processed through molding before or after molding, such as atomization, dyeing, surface vacuum or magnetron sputtering coating. The film has various functions required, such as light transmission and opacity similar to frosted glass, coated or dyed with different shades of color, and selective transmission of light from different wavelengths from ultraviolet to infrared. One end of these films with specific functions is wound on a reel mounted on the top of an insulating glass, and the other end is fixed on a bar with a certain weight. Or two ends of the film are wound on two reels respectively, and the two reels are respectively installed on two sides in the hollow glass in parallel.

The transmission structure of the built-in adjustable thin-film insulating glass of the present invention can have three basic transmission structure modes, which are used in occasions with different requirements. The first type is a direct drive type. The film reel is mounted on a support in an insulating glass. The film reel directly unwinds the film. At the same time, the film reel is driven by the inner magnetic part on the shaft end and the outer magnetic part on the outer coaxial line of the glass. The second type is a parallel shaft transmission type. There are two parallel shafts on the inner frame of the hollow glass, which are driven by gears. One of the shafts is a film reel for unwinding the film. The other is a transmission shaft. An internal magnetic transmission part and a screw nut can be installed on the shaft. The internal magnetic part and the external magnetic part arranged parallel to the outside of the glass do not contact the transmission. The screw and nut are used for positioning the rotating shaft. The third type is a vertical shaft transmission type. In the hollow glass, there are two shafts on each of the two sides that are perpendicular to each other. The two shafts are driven by bevel gears, and one of the shafts is a reel for unwinding the film. An inner magnetic part and a screw nut are mounted on the other shaft. The inner magnetic parts are arranged in parallel with the outside of the glass. The outer magnetic parts are not in contact with the drive. Screws and nuts are used to position the rotating shaft.

When the area of the insulating glass is large, such as when the height of the glass exceeds the unrolled length of a single roll of film, several film reels can be arranged in parallel in the glass by the first or third transmission method, and synchronized or controlled separately outside the glass. Unwinding of the film. If the width of the glass is too wide, a bracket can be added to the appropriate place of the reel to allow the film to be coaxially wound in sections.

The manufacturing method and transmission structure of the built-in adjustable thin-film insulating glass of the present invention can better solve the problem of installing adjustable curtains in the widely used hollow glass with small gaps. This type of insulating glass can greatly improve the related functions of insulating glass after being loaded with low-cost processing to obtain a variety of corresponding performance films. Insulating glass made with these ordinary glasses can truly have modern architectural requirements. Glass has comprehensive functions related to energy saving, intelligence, and intelligence.

For example, in terms of improving the energy saving of the insulating glass, the insulating glass produced by the present invention may obtain the best energy saving effect in each season. For example, insulating glass made of ordinary transparent glass has a poor anti-radiation heat transfer effect. If silver and other low-radiation films are plated inside the glass, the film can be unfolded when the sunlight is strong in summer. Most of the solar radiation is blocked outdoors and reduces the The airflow transfers heat and is a good blackout curtain. In winter, the film is rolled during the day, and most of the solar heat can be put into the room. At night, the film can be unrolled, which can prevent the indoor heat from being lost to the outdoors in the form of radiation.

In terms of increasing the dimming performance of the insulating glass, the present invention can realize the dimming effect of integrating the glass and the curtain. For example, two different sets of independent films can be installed in the insulating glass. One set of films is matt and opaque, and the other is dark and opaque, which becomes a day and night curtain suitable for day and night. It is also possible to apply different shades of color to different areas of the same film rolled in two axes. When the film is unfolded in different areas in the glass, the light transmittance is also changed, so that the hollow glass has stepless dimming. Effect.

The present invention will be described in further detail below with reference to the drawings and specific embodiments.
