Description

Technical Field

[0001] The present invention relates to the technical field of protective glass processing equipment, and particularly to a device for injecting fire-proof liquid into the inner cavity of protective glass. Background Art

[0002] Protective glass is a special glass product that can provide additional safety protection. It is usually processed specially and has characteristics such as impact resistance and explosion resistance. Protective glass is widely used in the construction industry and can be used in positions such as building windows, glass curtain walls, and skylights to enhance the safety of buildings. In addition, it is also used in the automotive field, such as the front windshield and side windshield of cars, which can effectively reduce the risk of injury to occupants when a vehicle accident occurs. Protective glass can be divided into various types according to different needs and uses. Among them, laminated glass and tempered glass are relatively common. Laminated glass fixes two layers of glass at intervals to form an inner cavity, and a fire-proof liquid is added inside the inner cavity to improve the fire-proof effect of the protective glass.

[0003] Currently, when adding fire-proof liquid into the protective glass, the protective glass is first clamped and positioned, openings are reserved at the four right angles of the protective glass in advance, then the pipeline of the liquid injection device is passed through the openings at the right angle positions of the protective glass and inserted into the inner cavity of the protective glass, and then the fire-proof liquid is introduced into the protective glass through the liquid injection device. Finally, the right angles of the protective glass are sealed. Although the liquid injection operation is simple, there are still the following problems:

[0004] 1. It is necessary to clamp the protective glass and then insert the pipeline of the liquid injection device into the inner cavity of the protective glass. The liquid injection process requires step-by-step operations, resulting in low liquid injection efficiency;

[0005] 2. When inserting the pipeline of the liquid injection device into the right angle opening of the protective glass, because the opening is small, it is generally difficult to accurately insert it into the right angle opening of the protective glass. The operation is very inconvenient, and it is also easy to cause the pipeline of the liquid injection device to collide with the glass, resulting in damage to the glass and reducing the quality of the protective glass;

[0006] In summary, there is a need for an injection device that can efficiently and accurately inject liquid into the protective glass. Summary of the Invention

Then, a right-angle sealing plate 85 is attached to the right-angle position, and a sealing plug 851 is inserted into the inner cavity for sealing.

[0057] The working principle and usage process of the present invention:

[0058] First, press Figures 1-9Take out the right-angle sealing plates 85 at two diagonals of the protective glass 8, pull out the sealing plugs 851 from the openings at the right-angle positions of the protective glass 8, then place the protective glass 8 on the L-shaped support plate 621, and then start the first motor 3 to drive the first screw 4 to rotate. The first screw 4 drives the translation frame 52 to slide on the U-shaped support frame 1. The slider 521 slides inside the first chute 11, and the guide rod 55 is inserted into the sleeve 56 in a guiding manner to improve the guiding property of the movement of the translation frame 52. The translation frame 52 drives the first positioning liquid injection mechanism 6 to move longitudinally as a whole and approach the second positioning liquid injection mechanism 7;

[0059] At the same time, start the second motor 53 to drive the second screw 54 to rotate, and drive the bottom plate 631 to move transversely on the translation frame 52, so that the first clamping plates 643 of the first positioning liquid injection mechanism 6 and the second positioning liquid injection mechanism 7 and the second clamping plates 653 are respectively attached to the four side edges of the protective glass 8 to pre-clamp the protective glass 8. At this time, the liquid outlet pipes 615 at the two diagonal positions are respectively aligned with the openings at the two right-angle positions on the protective glass 8;

[0060] Then start the third motor 636 to drive the first gear 634 to rotate. The first gear 634 drives the second gear 635 to rotate synchronously. The first gear 634 and the second gear 635 respectively drive the first toothed plate 641 and the second toothed plate 651 to move at the same time. The first sliding plate 642 drives the first clamping plate 643 to retract away from the side wall of the protective glass 8, and the second sliding plate 652 drives the second clamping plate 653 to retract away from the other side wall of the protective glass 8. During the retraction process of the first clamping plate 643 and the second clamping plate 653, start the first motor 3 and the second motor 53 again synchronously, so that the first positioning liquid injection mechanism 6 moves synchronously longitudinally and transversely, so that the first clamping plate 643 and the second clamping plate 653 can always clamp on the side edge of the protective glass 8, and the liquid outlet pipe 615 moves on the angular bisector of the L-shaped fixing frame 613 relative to the protective glass 8, so that the liquid outlet pipe 615 is accurately inserted into the right-angle opening inside the protective glass 8. Then start the water pump 611, and the fireproof liquid enters the liquid outlet pipe 615 through the liquid guide cylinder 614 and is introduced into the inner cavity of the protective glass 8 by the liquid outlet pipe 615;

[0061] After the liquid injection is completed, start the first motor 3, the second motor 53 and the third motor 636 to rotate in the reverse direction, drive the first positioning liquid injection mechanism 6 to move away from the second positioning liquid injection mechanism 7. At the same time, the first clamping plate 643 and the second clamping plate 653 keep clamping the protective glass 8, and the liquid outlet pipe 615 is pulled out from the inside of the protective glass 8. Finally, the sealing plug 851 is inserted into the right-angle opening inside the protective glass 8, and the right-angle sealing plate 85 is pasted at the right-angle position of the protective glass 8 to seal the protective glass 8.
