Film suspended hollow glass and manufacturing method and continuous production line thereof

Abstract

The invention discloses film suspended hollow glass. The film suspended hollow glass comprises front glass, spacing frames and suspended films, wherein the front glass is bonded with the spacing frames, the suspended films are connected with the spacing frames, the area of the front glass is larger than that of the spacing frames, and a matched positioning structure can be additionally arranged between the front glass and the spacing frames according to needs. Film stretching frames and rear glass are additionally added, the film stretching frames are connected with the spacing frames throughthe suspended films to obtain single-glass film suspended hollow glass, and matched concave-convex structures are arranged on the connecting surfaces between the film stretching frames and the spacingframes; and a piece of rear glass is adhered to the other side of each film stretching frame to obtain double-glass double-cavity film suspended hollow glass, and two pieces of single-glass film suspended hollow glass are connected to obtain double-glass three-cavity film suspended hollow glass. The invention further discloses a manufacturing method of the pieces of glass and a glass manufacturing production line.

Description

technical field [0001] The invention belongs to the field of hollow glass, and in particular relates to a hanging film hollow glass, a manufacturing method and a continuous production line thereof. Background technique [0002] With the development of green and energy-saving buildings, higher and higher requirements have been put forward for the thermal insulation performance of the glass used. It has gradually developed from the original single-cavity insulating glass to three-glass two-cavity or even four-glass three-cavity insulating glass. The increase of the hollow cavity brings the problem that the thickness and weight of the insulating glass are doubled, and the cost of the frame and hardware is also increased, so the cost of the door and window is also doubled; The technology of the intermediate glass of multi-cavity insulating glass has been gradually accepted by users and the market. Since the optical plastic film has the same optical properties as ultra-thin glas...

Problems solved by technology

However, due to the complexity of its processing technology, it is difficult to combine with glass, resulting in many problems such as low production efficiency and unstable quality.

[0004] The structural characteristics of the existing suspended film insulating glass determine that its structure is too complex, the production process is cumbersome, and the production process is difficult.

Therefore, since the commercial production of suspended film insulating glass, the insertion of elastic elements, the fixing and tensioning of optical plastic films, and the packaging of the inner and outer glass have become technical bottlenecks restricting automatic continuous production.

[0005] At the same time, in order to ensure that the suspension film has pre-tension and film surface flatness, the stability of the spacer frame, and the bonding strength and sealing requirements of the glass, the packaging width at the edge of the glass is too wide, which brings about the "cold edge" problem. Thus affecting the thermal insulation effect
