Description

Technical Field

[0001] The present application relates to the technical field of laminating equipment, and in particular to a laminated glass laminating equipment. Background Art

[0002] During the laminated glass production process, air bubbles form between the glass and the interlayer (e.g., PVB film) between the glass and the laminate. Laminating equipment, through pressure and other means, removes these bubbles, ensuring the transparency and aesthetics of the laminated glass. Commonly used laminating equipment for laminated glass production is vacuum bag laminating and autoclave laminating.

[0003] A search revealed that Chinese patent publication number CN220220041U discloses an autoclave for laminating laminated glass. Two sets of limit baffles are provided on a loading rack. When the laminated glass is placed, the limit baffles restrain the bottom of the laminated glass, preventing it from sliding outward and ensuring the stability of the laminated glass after placement. However, this device tilts the laminated glass group, which can easily cause the two glass sheets within the group to shift, affecting the quality of the laminated glass. Furthermore, although conventional technology places the laminated glass group horizontally, it is inconvenient to place multiple laminated glass groups into the interlayer of the loading rack when the groups are placed in layers. Therefore, a laminated glass laminating device is proposed to address the above-mentioned issues. Utility Model Content

[0024] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] The following describes in detail the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0026] See also Figure 1-7 , the utility model provides a technical solution for laminated glass pressing equipment:

[0027] A laminated glass pressing device includes a pressure autoclave 1, a lid 2 is provided on one side of the pressure autoclave 1, an electric heating wire is provided inside the pressure autoclave 1, an air pipe 3 is fixedly connected to the surface of the pressure autoclave 1, a bottom plate 4 is provided inside the pressure autoclave 1, a vertical shaft 5 is fixedly connected to the upper surface of the bottom plate 4, and a plurality of bearing units 6 are rotatably connected to the surface of the vertical shaft 5 for placing a laminated glass group 7. The upper bearing unit 6 can rotate around the vertical shaft 5 to avoid blocking the lower bearing unit 6.

[0028] Specifically, by providing a vertical axis 5 and a carrying unit 6 that can rotate around the vertical axis 5, after the laminated glass group 7 is placed on the upper carrying unit 6, the carrying unit 6 can be moved to rotate to the other side of the vertical axis 5 to prevent it from blocking the lower carrying unit 6, making it convenient to place the next group of laminated glass groups 7 on the lower carrying unit 6. At the same time, during the pressing process, multiple carrying units 6 can be rotated to a staggered state, which can increase the spatial distance between two adjacent carrying units 6, thereby improving the uniformity of heat transfer and pressure uniformity, and thereby improving the efficiency of bubble discharge. Therefore, the laminated glass pressing equipment solves the problem in the prior art that it is inconvenient to load multiple groups of laminated glass groups 7 into the carrier, wherein the pressure autoclave 1 is connected to the autoclave cover 2 by a flange.

[0029] The load-bearing unit 6 is connected to the vertical shaft 5 through a rotating component, which is a damping bearing. The damping bearing is provided to prevent the load-bearing unit 6 from deflecting under small vibrations. The damping bearing is an existing technology. It is a bearing with damping characteristics based on traditional bearings through special structural design or adding damping materials.

[0030] The supporting unit 6 includes a supporting plate 601. The upper surface of the supporting plate 601 is provided with a through hole. A plurality of support bars 602 are fixedly connected within the through hole to form a supporting area. The provision of the support bars 602 reduces the obstruction of the contact between the lower surface of the laminated glass group 7 and the gas in the reactor, thereby increasing the contact area between the lower surface of the laminated glass group 7 and the gas in the autoclave 1, so that the laminated glass group 7 is evenly heated and pressurized.

[0031] A mounting opening is provided on the upper surface of the carrying plate 601, and a bidirectional threaded screw 603 is rotatably connected to the inner wall of the mounting opening. Two internal thread blocks 604 are respectively threadedly connected to the two rotational sections on the surface of the bidirectional threaded screw 603. A clamping rod 605 is fixedly connected to the upper surface of the internal thread block 604, and a slider 606 is fixedly connected to the lower surface of the clamping rod 605. A slideway is provided on the upper surface of the carrying plate 601, and the slider 606 is slidably connected to the slideway. One end of the bidirectional threaded screw 603 extends to the outside of the carrying plate 601 and is fixedly connected to a handwheel 607. By rotating the handwheel 607, the bidirectional threaded screw 603 is driven to rotate, thereby driving the two sliders 606 closer to each other, and then driving the two clamping rods 605 closer to each other and clamping and fixing the laminated glass group 7, preventing the glass sheets from being offset due to vibration and improving the pressing quality.

[0032] Two support rods 8 are fixedly connected to the upper surface of the base plate 4, and a plurality of support blocks 9 are fixedly connected to the surface of the support rods 8 along the axial direction. Two notch grooves 10 are respectively provided on the front and rear sides of the upper surface of the supporting plate 601, wherein the upper surface of the support block 9 and the lower surface of the corresponding supporting plate 601 are in the same horizontal plane. The support block 9 can provide auxiliary support to the supporting plate 601 to improve the stability of the device.

[0033] The inner bottom wall of the autoclave 1 is formed with a horizontal support surface 11 , the upper surface of the support surface 11 is fixedly connected to a guide rail 12 , and the lower surface of the bottom plate 4 is fixedly connected to a limit block 13 , which is slidably connected to the guide rail 12 .

[0034] The air pipe 3 is connected to the external inert gas storage equipment, and a solenoid valve 14 is provided on the surface of the air pipe 3. The inert gas is injected into the pressure tank through the air pipe 3. The surface of the pressure tank is also provided with an exhaust pipe 3 and an exhaust valve for discharging the initial gas in the pressure vessel 1. The exhaust pipe 3 and the exhaust valve are not shown in the figure.

[0035] Working principle: When the laminated glass pressing equipment is used, the initial state is as follows: Figure 6 As shown, all the carrying units 6 are located on the same side, and then the first group of laminated glass groups 7 is placed on the uppermost carrying area, and then the hand wheel 607 is rotated, and the hand wheel 607 drives the bidirectional threaded screw 603 to rotate, and the bidirectional threaded screw 603 drives the two sliders 606 to move closer to each other, and the two sliders 606 drive the two clamping rods 605 to move closer to each other and clamp the laminated glass group 7 to prevent the glass sheets from shifting due to vibration and improve the pressing quality. Then, the uppermost carrying unit 6 is rotated to the other side, and the second group of laminated glass groups 7 is placed on the second layer of carrying units 6 in the same way. After the laminated glass group 7 is placed in this manner, one of the two adjacent carrying units 6 is rotated so that the multiple carrying units 6 are arranged in a staggered manner. Then, the limit block 13 is aligned with the guide rail 12, and the bottom plate 4, the carrying unit 6, and the laminated glass group 7 are pushed into the autoclave 1 and the autoclave cover 2 is closed. Then, inert gas is injected into the autoclave 1 through the air pipe 3. When the initial air in the autoclave 1 is discharged and the set pressure value is reached, the pressure is maintained and the electric heating wire is started to heat the laminated glass. The laminated glass pressing work is completed. Therefore, the laminated glass pressing device solves the problem of the inconvenience of loading multiple laminated glass groups into the carrier in the prior art.
