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

[0042] Example 1: Bandage assembly and bandage method

[0043] 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.

[0044] 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

[0052] Embodiment 2: stretch film frame assembly deformation one

[0053] 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

[0056] Embodiment 3: stretch film frame assembly deformation two

[0057] 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.

[0058] The present invention has following characteristics:

[0059] 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 can be adj...

Abstract

The stretching method and the stretching film assembly of the hollow glass inner suspension optical film are composed of a rotating frame and a structural frame made of a co-extruded polymer profile with a gradient modulus distribution. The rotation of the rotating frame around the fulcrum of the structural frame drives the On the rotating frame, the protruding chucks are distributed in dots at intervals to realize the stretching of the film. The chuck that fixes the film around the film has good elasticity and low modulus to generate the force to pull the film outwards, and can produce a small tension in any direction of 360o with the tension film and the change of film stress during use. deformation, thereby maintaining the flatness of the film. The structural frame with high modulus ensures good dimensional stability of the entire stretch film assembly. The dry spacer frame with two horizontal and vertical chambers replaces the traditional spacer frame and cooperates with the optical film to realize the double insulating glass packaging structure. The invention controls the tension of the inner hanging film through the rotation and cooperation of the stretch film components, so that the quality and efficiency of the inner hanging film can be 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...
