Problems solved by technology

Under the condition that only the same kind of spring can be used, it is difficult to guarantee the consistency of product performance
[0009] The inner suspension film technology using springs as elastic elements is cumbersome and difficult to operate, and the arrangement of springs is arbitrarily random, which makes it difficult to control the quality of the film
Due to the characteristics of the spring, the welding operation is difficult, and it is prone to solder joint quality problems such as over-welding, missing welding or virtual welding.
The quality of the solder joints directly affects the flatness of the film surface, and the quality problem of a single solder joint will lead to the welding failure of the entire film
These have become difficult problems for automated production and processing

Embodiment 1

[0045] Example 1: Bandage assembly and bandage method

[0046] like figure 1 As shown, the new technology of the hollow glass inner suspension membrane of the present invention is to complete the assembly of the inner suspension membrane of the insulating glass in a purification workshop with a certain level.

[0047] The stretch film assembly is assembled from a structural frame 4 and a rotating frame 5 . Structural frame 4 is an extruded profile with high modulus polymer (see figure 2 ). The rotating frame 5 is a co-extruded polymer profile with a special structure and a gradient modulus distribution (see image 3 ), the clamp 5.5, the clamp 5.3, the knob 5.2 and the main cavity are all extruded with high modulus raw materials, while the clamp 5.1 requires materials with a small modulus and good elasticity and recovery deformation ability to be co-extruded with the aforementioned parts into a profile. Chuck 5.1 During the co-extrusion process, it is cut in a zigzag ...

Embodiment 2

[0056] Embodiment 2: stretch film frame assembly deformation one

[0057] like Image 6 As shown, the rotating frame can also be replaced by a polymer structural section with a three-claw shape. The common point of the three claws is used as a rotating fulcrum and is also called a turning button. The claw on the side of the rotating frame close to the hollow glass cavity serves as a Decorative end plate (the end is used as the flange of the stretch film), the middle claw of the three-claw shape is the fixed side of the inner suspension film, and the end of the fixed side is a group of protruding chucks distributed at intervals, which are in direct contact with the film , with good elasticity and low modulus, and a tight contact point between the film and the chuck that can move in a small range is obtained by welding; the outer claw of the rotating frame close to the sealing structure of the outer end of the insulating glass has a backstop The locked tooth socket is called ...

Embodiment 3

[0061] Embodiment 3: stretch film frame assembly deformation two

[0062] like Figure 7 As shown, the rotating frame is also replaced by a polymer structural profile with a three-claw shape in cross-section, wherein the rotating fulcrum, that is, the turning button, is arranged on the fixed plate of the L-shaped structural frame near the inner end, and cooperates with the rotating fulcrum, that is, the turning button. The grooves are arranged on the rotating frame, and the processing and assembly of the stretch film assembly are as described in Examples 1 and 2.

[0063]

[0064] The present invention has following characteristics:

[0065]The rotating frame and the structural frame, which are composed of co-extruded polymer profiles with special structure and gradient modulus distribution, rotate around the fulcrum in the structural frame through the rotating frame, driving the chuck on it to pull the plastic film outward along the film periphery. Tighten, the chuck c...

Abstract

The invention discloses a method for film stretching of an internally-suspended film of hollow glass and a film stretching frame assembly. The film stretching frame assembly is composed of a rotary frame and a structure frame which are made of co-extrusion polymer section bars with gradient modulus distribution, the rotary frame rotates around a pivot inside the structure frame, so that protruding chucks distributed on the rotary frame in a spot shape and arranged at intervals are driven, and therefore a thin film can be stretched. The chucks fixing the periphery of the thin film are good in elasticity and low in modulus so that the force enabling the film to be stretched outwards can be generated, the chucks can slightly deform in any direction at 360 degrees along with the change of the stress of the thin film in the process of film stretching and use, and therefore flatness of the thin film can be kept. According to the structure frame with the high modulus, good size stability of the whole film stretching frame assembly can be guaranteed. A dry division bar frame provided with a vertical chamber and a transverse chamber replaces a traditional spaced frame and is matched with an optical film so that a double-sealing structure of the hollow glass can be achieved. According to the method for film stretching of the internally-suspended film of the hollow glass and the film stretching frame assembly, rotation of the film stretching frame assembly controls the tension of the internally-suspended thin film in a matched mode, and therefore the quality and the efficiency of the internally-suspended thin film are reliably guaranteed.

Description

technical field [0001] The invention belongs to the technical field of exterior protection of green energy-saving buildings, in particular relates to building energy-saving door and window systems and curtain wall systems, and provides a multi-hollow glass manufactured by inner suspending film stretch film components. Background technique [0002] Energy-saving buildings have higher and higher requirements for the optical and thermal performance of insulating glass, and technologies such as adding a heat-insulating hollow layer, filling inert gas, and low-emissivity coatings have been widely used. The addition of the insulating hollow layer will be restricted by multiple factors such as the material properties of the middle insulating layer, the difficulty of installation, and the impact on the overall structural strength and sealing. [0003] Double insulating glass made of glass is a relatively common technology, but the addition of intermediate glass makes the overall we...
