Technical Field

[0001] The present invention relates to the field of toughened laminated glass, and particularly to a multifunctional toughened laminated glass and its processing technology. Background Art

[0002] Toughened laminated glass is a composite material with high strength and high safety. It is usually composed of two or more pieces of toughened glass bonded together by an intermediate interlayer material (such as PVB or EVA). The interlayer material can not only improve the impact resistance of the glass but also prevent the fragments from flying when the glass is broken, thus enhancing the safety performance. This material is widely used in fields such as construction and automobiles to provide additional protection and durability.

[0003] There are the following problems in the existing toughened glass and its production process: the side lacks protection, which is easy to cause edge damage and crack propagation. And if it is necessary to coat a protective material on the side during the processing, manual scraping treatment is required, resulting in low work efficiency and waste of manpower.

[0041] Please refer to Figure 6 , Figure 7 and Figure 8, the adjusting mechanism 5 includes a fixing plate 51 for support. The lower left end of the front face of the fixing plate 51 is fixed to the support plate 1. The middle part of the back face of the fixing plate 51 is welded with a side frame 52. A third motor 53 is arranged on the back face of the side frame 52. A transmission component 54 is arranged in the middle of the fixing plate 51. The back of the transmission component 54 is connected to the third motor 53. Two guide members 55 are arranged at the front end of the transmission component 54. The front end of the bottom of the guide member 55 is connected to the top of the moving plate 3;

[0042] The transmission component 54 includes a gear 542 connected to the output shaft of the third motor 53. The bottom of the gear 542 meshes with a rack 543. The back of the rack 543 is matched with a guide rod 544. The back of the guide rod 544 is connected to the side frame 52 for support. Both ends of the front face of the rack 543 are connected to a displacement plate 546 through support rods 545. Two raised seats are fixed at both ends of the back face of the displacement plate 546.

The upper and lower ends of the support member 551 are hinged with main pulleys 552. The main pulleys 552 are in contact with the upper and lower ends inside the guide rail 547.

The bottom of the stabilizing member 554 is fixed to the moving plate 3. The moving plate 3 moves along with it.

[0044] The specific implementation process is as follows:

[0045] When it is necessary to evenly scrape the side of the glass coated with the upper side stabilizing layer d, by starting the first motor 62 to work, the first motor 62 drives the threaded rod 63 to rotate. During the rotation of the threaded rod 63, the sliding block 64 can be driven to move. The sliding block 64 drives the top support plate 2 through the connecting block 65. The support plate 2 moves to receive the glass from the previous station and sends it to the scraping position, that is, the top of the support plate 1;

[0046] Then start the third motor 53 to work. The third motor 53 drives the gear 542 to rotate. During the rotation of the gear 542, the rack 543 can be driven to move. The rack 543 moves under the guidance of the guide rod 544 and drives the displacement plate 546 through the support rod 545. The guide member 55 connected to the front end of the displacement plate 546 cooperates with the internal pulley 552 to move in the guide rail 547. During the movement, the moving plate 3 connected to the front stabilizing member 554 moves along and moves towards the glass on the support plate 2;

[0047] During the movement, the second motor 45 operates, driving the pulley 412 to rotate. The scraping belt 413 outside the pulley 412 can then move accordingly. During the movement, when it comes into contact with the side stabilizing layer d coated on the side of the glass, it evenly scrapes and levels it. The reciprocating scraping and leveling can be achieved by driving the third motor 53 to rotate forward and backward. After the scraping and leveling is completed, the moving plate 3 can be reset, and at the same time, the glass is sent out through the support plate 2.

[0048] When the scraping belt 413 needs to be cleaned, connect the water inlet pipe 43 to an external water supply device to allow water to enter the box body 411. Then start the second motor 45 to make the scraping belt 413 move. Next, start the cylinder 44 to operate. The push rod at the bottom of the cylinder 44 drives the bracket 417 below to move up and down, so that the inner cleaning brush 418 cleans the scraping belt 413 during movement, and the sewage is discharged through the opening at the bottom.

[0049] The above are only the preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
