Detailed Description

In order to more clearly understand the technical features, objects, and effects of the present application, embodiments of the present application will now be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.

An inner suspension film door and window as shown in fig. 1-2 comprises two glass sheets 1, and an inner suspension film 2 is arranged in a cavity between the two glass sheets 1, but it should be understood by those skilled in the art that two or more inner suspension films 2 can be arranged between the two glass sheets 1 according to the requirement.

The inner suspension film 2 is made of a plastic film with good heat-resistant and insulating effects, and needs to be tensioned between hollow glasses to keep light rays transmitted in parallel and avoid visual deformation.

In order to facilitate installation, the inner suspension film 2 is arranged in a tensioning frame 3 in a tensioning state, the tensioning frame 3 and the inner suspension film 2 in the tensioning state can be installed between two layers of glass 1 as an independent part, and therefore the problem of field tensioning of the inner suspension film 2 does not need to be considered when the glass door window is installed, and installation complexity is reduced. Further, in the illustrated embodiment, both sides of the tension frame 3 may be bonded between the two sheets of glass 1 by spacer bars 4. For example, the spacer 4 may be an existing composite butyl aluminum spacer, butyl rubber for adhesion is provided on both sides of the spacer 4, and a molecular sieve for adsorbing water vapor is provided in a hollow structure inside the spacer 4.

The tensioning operation of the inner suspension film in the prior art is very complicated, four edges of the inner suspension film need to be clamped on a plurality of elastic elements respectively during installation, and the tensioning force needs to be locally and repeatedly adjusted in order to prevent wrinkling. In order to solve the above problem, as seen in the exploded perspective view of the tension frame 3 shown in fig. 2, the four sides of the inner suspension film 2 of the present application are respectively wound around four reels 21, both ends of the four reels 21 are respectively snap-fixed together by corner connectors 60 (to be described in detail later), and then the inner suspension film 2 tensioned by the reels 21 and fixed by the corner connectors 60 can be disposed inside the tension frame 3 between the two sheets of glass 1.

In one illustrated embodiment, in order to facilitate the exposure of both ends of the winding shaft 21 while tensioning the inner suspension film 2, the inner suspension film 2 is rectangular with four corners cut off so that the width of the four sides of the inner suspension film 2 becomes narrower as they approach the edge positions, and thus the winding thickness of the inner suspension film 2 on the winding shaft 21 becomes thicker as it approaches the middle of the winding shaft 21 and becomes thinner as it approaches both ends of the winding shaft 21 when wound on the winding shaft 21. That is, the inner suspension film 2 wound around the bobbin 21 is formed into a spindle shape having a thick middle and thin ends. Therefore, as the inner suspension film 2 is tightly wound on the winding shaft 21, the tension of the middle position of the inner suspension film 2 is gradually greater than that of the corner positions, and the stretching and loosening of the film caused by the thermal expansion of the middle suspended inner suspension film can be counteracted. Meanwhile, the winding edge of the inner suspension film 2 tends to extend towards the two thinner ends, so that the phenomenon of wrinkles caused by local extrusion of the film is naturally eliminated.

In order to facilitate the winding of the inner suspension film 2 by the winding shaft 21 to generate a uniform tension, it is preferable that the section of the middle portion of the winding shaft 21 for winding the inner suspension film 2 is circular. In addition, in order to facilitate the connection of the corner connector 60 without loosening the tension after the tension, the cross section of the reel 21 for connecting both ends of the corner connector 60 is square, so that the reel 21 is not easily rotated.

This application is through rolling up four limits of interior suspension membrane respectively on four spools, can obtain bigger tensile force in the middle part of interior suspension membrane, has offset interior suspension membrane be heated relaxation, has eliminated the fold through coiling nature simultaneously, therefore when installing on the tensioning frame, only need the both ends of tensioning spool, need not adjust the tensile force one by one to every position of periphery of interior suspension membrane, greatly reduced the complexity of tensioning operation.

Further, as shown in fig. 2, the tension frame 3 includes a first frame body 31 and a second frame body 32 disposed on both sides of the internal suspension film 2 in a sandwiched manner. In the illustrated embodiment, four corner connectors 60 are provided at the corners of the four reels 21. The corner connector 60 may be fixedly installed inside the tension frame 3 by means of screwing, welding or bonding, so that the inner suspension membrane 2 in a tensioned state may be fixedly installed inside the tension frame 3.

As can be seen from the above description, in order to reduce the complexity of the mounting operation of the inner suspension film 2, it is first necessary to wind the inner suspension film 2 on the reel 21 and keep the inner suspension film 2 in a tensioned state. As shown in fig. 3, in general, the inner suspension film 2 made of a plastic film needs to be cut into a shape convenient for winding, that is, a rectangular film is cut at four corners, and the inner suspension films 2 having the cut shapes are stacked one on another. Then, four reels 21 are placed over the four edges of the inner suspension film 2 for the winding operation, the four edges of the inner suspension film 2 are fixedly connected to the four reels 21, respectively, for example, by gluing or double-sided tape, and the four edges of the inner suspension film 2 are bonded to the four rotating shafts 21, and finally, the reels 21 are rotated to wind the inner suspension film 2 on the reels 21.

As can be seen from the schematic diagram shown in fig. 3, although it does not seem complicated to wind the inner suspension film 2 on the winding shaft 21, in order to maintain the tension state of the inner suspension film 2 during the winding process, four rotating shafts 21 are required to be operated simultaneously and cannot be loosened, and any angular deviation causes the four winding shafts 21 after winding to fail to maintain the correct position, thereby causing the tension of the inner suspension film 2 to fail and being unavailable for installation between hollow glasses.

In order to solve the problems that the tensioning operation of the inner suspension film 2 is complex and easy to fail, the application provides an inner suspension film winding device which is used for winding four edges of the inner suspension film 2 on four reels 21 respectively and installing the inner suspension film 2 wound on the reels 21 in a tensioning manner inside a tensioning frame 3 between two layers of glass 1, as shown in the figure. Through the mechanical structure of the winding equipment, the winding equipment can realize more accurate alignment and coordinated uniform winding operation relatively to manual operation, avoids the problem of different angle deviation and winding tightness, and improves the integral tensioning quality and the production efficiency.

As shown in the figure, the winding device of the present application includes four belt pressing mechanisms 7 pressed above four reels 21, the four belt pressing mechanisms 7 are respectively pressed above the four reels 21 disposed on four sides of the inner suspension film 2, and the belt pressing mechanisms 7 rub the reels 21 to rotate by the friction force of the belt, so as to respectively tension and wind the four sides of the inner suspension film 2 on the four reels 21; the ends of the four reels 21 on which the inner suspension film 2 is wound under tension can be respectively fastened together by corner connectors 60 to maintain the tension of the reels 21 on the inner suspension film 2.

For the convenience of winding, as mentioned above, the four edges of the inner suspension film 2 may be fixedly connected to the four winding shafts 21, for example, glue is applied to the four edges of the inner suspension film 2, or a double-sided tape is adhered to the winding shafts 21 in advance. For example, when the reel 21 is disposed on the four edges of the inner suspension film 2, the protective film on the double-sided adhesive tape may be torn off, and then the reel 21 is pressed downward to bond the four edges of the inner suspension film 2 to the four rotating shafts 21.

As shown in fig. 6, the belt pressing mechanism 7 includes a pressing frame 71, two belt pulleys 72 are provided in the pressing frame 71, a belt 73 is provided around the two belt pulleys 72, and the belt pulleys 72 are driven by a motor 74 to reciprocate the belt 73 around the belt pulleys 72.

The belt 73 may be made of rubber or the like, has a certain friction and elasticity, and may be pressed against the middle of the winding shaft 21 by the lower surface of the belt 73, so that the winding shaft 21 may be twisted to rotate and the inner suspension film 2 may be wound on the winding shaft 21 one by one when the belt 73 moves around the pulley 72.

In the present application, the operation of winding the inner suspension film 2 on the reel 21 is mechanically handled by the four belt pressing mechanisms 7, and as long as the positions of the stacked inner suspension film 2 and the belt pressing mechanisms 7 are kept accurate, it is ensured that the angle of the winding operation does not deviate. In addition, because the belt 73 of the belt pressing mechanism 7 is elastic, the pressing and twisting force can be kept uniform, and relative sliding cannot occur, the number of winding layers can be controlled by only controlling the rotating speed and time of the motor 74, and the winding precision can be well ensured without worrying about the influence of human factors.

Fig. 4 shows a situation that four sides of the inner suspension film 2 are twisted and wound on four reels 21 by the belt pressing mechanism 7, and then the ends of the reels 21 can be respectively snap-fixed by the corner connectors 60. The four reels 21 holding the four corners are not relatively displaceable to thereby establish a fixed tension state, and the tension operation of one piece of the inner suspension film 2 is completed. Thereafter, the belt pressing mechanism 7 may be lifted, the tensioned inner suspended film 2 may be removed, the four reels 21 may be disposed again above the stacked inner suspended film 2, and the belt pressing mechanism 7 may be pressed above the four reels 21, and the next tensioning operation may be repeated.

As shown in fig. 4-5, further, in an embodiment, the belt pressing mechanism 7 may be fixedly mounted on an operation frame 8, and the operation frame 8 may be connected to a robot arm (not shown) or other driving mechanism via a cross beam 9 or the like for precisely controlling the pressing, lifting and positioning of the four belt pressing mechanisms 7. In the figure, a connecting column 81 is provided below the operating frame 8 corresponding to each belt pressing mechanism 7, and the belt pressing mechanisms 7 are fixedly connected to the ends of the connecting columns 81.

Still further, as shown in fig. 7, the operation frame 8 is provided with positioning hooks 82 corresponding to end positions of the four reels 21, and the ends of the reels 21 abut on the positioning hooks 82. As shown in the drawing, two positioning hooks 82 are provided for each reel 21, for a total of eight. Because the cross-section of the end of the reel 21 is square, the positioning hook 82 is bent into a right angle, and therefore two surfaces of the end of the reel 21 can be just attached to the right-angle edge of the positioning hook 82. The outer width of the two positioning hooks 82 corresponding to each reel 21 can be exactly equal to the length of the reel 21, so that the position of the reel 21 can be well determined when the reel 21 is placed above the two positioning hooks 82. Of course, other types of positioning hooks 82 may be provided, corresponding to the shape of the end of the reel 21.

When the reel 21 is placed above the stacked inner suspension film 2, first, both ends of the reel 21 are aligned and placed above the positioning hooks 82, the middle portion of the reel 21 slightly pushes up against the belt 73 of the belt pressing mechanism 7, so that the belt 73 is slightly bent upward, the middle portion of the reel 21 is pressed against the lower surface of the belt 73 of the belt pressing mechanism 7, and the reel 21 is firmly clamped. When the belt pressing mechanism 7 presses the edge of the stacked inner suspension film 2 downwards, the inner suspension film 2 pushes against the winding shaft 21 to further bend the belt 73 upwards, the operating frame 8 fixedly connected with the belt pressing mechanism 7 moves downwards relative to the belt 73 along with the bending of the belt 73, so that the positioning hook 82 is separated from the end part of the winding shaft 21, and when the belt pressing mechanism 7 rotates the winding shaft 21, the positioning hook 82 does not hinder the rotation of the winding shaft 21.

Further, as shown in the drawings, in a specific embodiment, the corner connector 60 includes two slots 61 arranged at a right angle, the cross section of each slot 61 corresponds to the cross section of the end of the winding shaft 21 (the size of each slot 61 is slightly larger than the end of the winding shaft 21), so that the ends of two adjacent winding shafts 21 arranged at a right angle can be respectively clamped in one slot 61. In order to prevent the end of the reel 21 from coming out of the notch 61, a stop slope 62 is provided at the top of the inner side of the notch 61. When the film winding device is installed, the end of the winding shaft 21 is pressed into the clamping groove 61 downward along the clamping inclined surface 62 (the inner suspension film 2 has elasticity and can be slightly elongated for a while and then restored), then the end of the winding shaft 21 is clamped below the clamping inclined surface 62, and under the tension of the inner suspension film 2, the inner side wall of the clamping groove 61 abuts against the tail end of the winding shaft 21. If the corner connector 60 is to be removed, the end of the reel 21 is pulled out a little distance along the slot 61, so that the end is disengaged from the restriction of the inclined plane 62, and the corner connector 60 can be removed smoothly.

As described above, the inner suspension film 2 tensioned by the reel 21 and fixed by the corner connector 60 may be directly disposed between the two sheets of glass 1, for example, double-sided adhesive tapes may be disposed on both sides of the corner connector 60 and bonded between the spacer bars between the two sheets of glass 1, so that the tensioning frame 3 is not required. Alternatively, the inner suspension film 2 tensioned by the reel 21 and fixed by the corner connector 60 may be directly disposed inside the tension frame 3 between the two sheets of glass 1 (e.g., bonded inside the tension frame 3 by a double-sided adhesive tape), and the tension frame 3 may be provided with the spacer 4 on both sides, as described above. The inner suspension film 2 under the two setting modes is a one-time tensioning structure and is suitable for inner suspension film doors and windows with small temperature difference deformation influence.

However, to the great interior membrane that hangs of temperature difference deformation influence, it is expend with heat and contract with cold repeatedly in long-term use, can lead to interior membrane extension after unable the recovery to make the interior membrane of hanging of extension crooked, fold, influence glass door and window's permeability, observe outdoor scenery can produce visual deformation because of the refraction. To avoid this problem, an elastic tension device (not shown) such as a spring may be further installed inside the tension frame 3 for pulling the end of the reel 21 to maintain tension in response to the elongation of the inner suspension film. In this case, the corner connectors 60 become a temporary part, and when the inner suspension film 2 is mounted inside the tension frame 3, the corner connectors 60 are detached one by one and hung on the corresponding elastic tension devices.

It should be appreciated by those skilled in the art that while the present application is described in terms of several embodiments, not every embodiment includes only a single embodiment. Such descriptions are merely for clarity reasons and should be understood by those skilled in the art as a whole and the technical solutions involved in the embodiments should be considered as being combinable with each other into different embodiments to understand the scope of the present application.

The above description is only illustrative of the present invention and is not intended to limit the scope of the present invention. Any equivalent alterations, modifications and combinations that may be made by those skilled in the art without departing from the spirit and principles of this application shall fall within the scope of this application.
