Description

Technical Field

[0001] The invention relates to the technical field of hollow glass production, and in particular to a hollow glass plate pressure-inflating device and a hollow glass production line. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In the current insulating glass production line, the space between two adjacent glass plates is inflated by a plate pressing and inflating device. For example, patent CN212051138U discloses a plate pressing and inflating mechanism and a plate pressing and inflating insulating glass production line. An inflatable member is arranged on the angle iron, and the angle iron is moved by a first inflating cylinder and a second inflating cylinder. When the first glass plate fixed by the second pressing member through the vacuum suction cup moves to a set distance from the spacing bar of the second glass plate on the lifting mechanism, the first inflating cylinder and the second inflating cylinder work together to move the inflatable member to the bottom of the gap between the two glass plates, and then inflate. After the air is inflated, the second pressing piece continues to move to press the two glass plates together. At this time, the vacuum suction cup is separated from the first glass plate, and then the pressed vacuum glass is sent out. When this structure is adopted, if vacuum glass with three or more glass plates is produced, the two or more pressed glass plates need to be retreated under the drive of the vacuum suction cup. At this time, except for the glass fixed by the vacuum suction cup, the other glass plates are not supported and are suspended. During the feeding process of new glass plates, the suspended glass plates are only fixed by the bonding force of the glue.

[0038] like Figure 4-6 As shown, an inflation mechanism is provided at the bottom end of the second pressure plate assembly 2 , and the inflation mechanism is used to inflate air between the two glass plates. The inflation mechanism includes a telescopic driving member, a lifting driving member, a first connecting member 11 and a second connecting member 12 .

[0039] The telescopic driving member adopts a telescopic driving cylinder 10, and the first connecting member 11 adopts an L-shaped plate, the L-shaped plate includes a first plate portion and a second plate portion, wherein the first plate portion is fixed to the bottom surface of the skeleton of the second pressure plate assembly 2 by multiple bolts, and the second plate portion is connected to the piston rod of the telescopic driving cylinder 10, and the axis of the telescopic driving cylinder 10 is arranged perpendicular to the second pressure plate assembly 2.

[0040] The cylinder body of the telescopic driving cylinder 10 is fixedly connected to the second connecting member 12 , and can drive the second connecting member 12 to move in a direction perpendicular to the second pressure plate assembly 2 .

[0041] The second connecting member 12 adopts a Z-shaped structure, including a first connecting part, and the two ends of the first connecting part are respectively provided with a second connecting part and a third connecting part facing oppositely, wherein the first connecting part is fixed to the cylinder body of the telescopic driving cylinder 10, and the third connecting part is connected to the lifting driving member, and the lifting driving member adopts the lifting driving cylinder 13, and the cylinder body of the lifting driving cylinder 13 is fixed to the third connecting part, and its piston rod is connected to the inflatable member 14, which can drive the inflatable member 14 to perform lifting and lowering movements.

[0042] In this embodiment, a first slider 15 is provided on the second connecting portion, and the first slider 15 is slidably connected to a first guide rail provided on the first plate portion of the first connecting member 11. The first guide rail is provided along the output movement direction of the telescopic driving cylinder 10 and is used to guide the movement of the second connecting member 12.

[0043] The inflatable member 14 is provided with a second slider 16 , which is slidably connected to a second guide rail provided on the first connecting portion. The second guide rail is provided along the output movement direction of the lifting drive cylinder 13 to guide the lifting movement of the inflatable member 14 .

[0044] The inflatable part 14 adopts an L-shaped structure, including a connecting part and an inflatable part, and a plurality of stiffening plates are arranged between the connecting part and the inflatable part, wherein the connecting part is slidably connected to the second connecting part 12 through a second guide rail and a second slider 16, and the connecting part is fixedly connected to the piston rod of the lifting drive cylinder 13, and the top surface of the inflatable part is provided with a plurality of grooves arranged at equal intervals to form a plurality of air chambers 17, and an air supply channel connected to the air chamber 17 is also provided in the inflatable part, and the air inlet end of the air supply channel is connected to the air supply mechanism, and the arrangement of the air supply mechanism, the air supply channel and the air chamber 17 can adopt the existing technology, which will not be described in detail here.

[0045] A support block 18 is provided on the upper surface area of ​​the inflation part between the adjacent grooves. The support block 18 is provided between the adjacent grooves to avoid the support block 18 affecting the inflation. At the same time, the position of the support block 18 is staggered with the position of the pushing member 9 to avoid the support block 18 and the pushing member 9 from interfering with each other so that the support block 18 can move between the top blocks of two adjacent pushing members 9. Countersunk holes are provided at both ends of the support block 18. The support block is fixedly connected to the inflation part through the countersunk holes and threaded fasteners. Preferably, the threaded fasteners are bolts or screws, which can be selected by technical personnel in this field according to actual needs. The countersunk depth of the countersunk hole is greater than the head thickness of the bolt or screw.

[0046] The stroke of the lifting mechanism is determined, therefore, the position of the glass plate on the second pressure plate assembly 2 is determined, therefore, the thickness of the support block 18, that is, the distance between the upper surface of the support block 18 and the upper surface of the inflation portion, is a set value, that is, the thickness of the support block is a set thickness, and the set thickness enables the upper surface of the support block 18 to contact the lower surface of the glass plate when the piston rod of the lifting drive cylinder 13 is extended to the maximum value, that is, the upper surface of the support block 18 is flush with the top surface of the top block, thereby supporting the glass plate.

[0047] At the same time, if Figure 7 As shown, a receiving groove 19 is provided at the bottom of the pressure plate of the second pressure plate assembly 2, and the receiving groove 19 matches the support block 18, so that when the telescopic driving cylinder 10 and the lifting driving cylinder 13 are in the maximum contraction state, the support block 18 can be located inside the receiving groove 19.

[0048] The specific set thickness of the support block 18 can be set according to actual needs.

[0049] The working method of the hollow glass plate pressure inflation device of this embodiment is that the hollow glass is made of three glass plates.

[0050] First, the first glass sheet enters the conveying mechanism and is supported by a plurality of conveying rollers 6 , and the first glass sheet rests on the pressure plate of the first pressure plate assembly 1 , and then the lifting mechanism works to lift the first glass sheet off the conveying rollers 6 .

[0051] The pressing drive mechanism drives the second pressing plate assembly 2 to move toward the first pressing plate assembly 1 until the vacuum suction cup contacts the glass plate. The vacuum suction cup works to adsorb and fix the first glass plate. Then the pressing drive mechanism drives the second pressing plate assembly 2 to move in the reverse direction and the lifting mechanism is reset at the same time.

[0052] The second glass plate with the spacer bar enters the conveying mechanism, and the lifting mechanism works to lift the second glass plate to make it separate from the conveying roller 6.

[0053] The pressing driving mechanism drives the first glass plate to move toward the second glass plate until a set distance is formed between the first glass plate and the spacing strip of the second glass plate.

[0054] The telescopic driving cylinder 10 works to drive the inflatable member 14 to extend to the bottom of the space between the two glass plates. The lifting driving cylinder 13 works to drive the inflatable member 14 to rise until the support block 18 contacts the bottom surfaces of the two glass plates. Then the air supply mechanism works to inflate the space between the two glass plates. After the inflation time is set, the pressing driving mechanism drives the first glass plate to move toward the second glass plate to achieve the pressing of the two glass plates.

[0055] After the pressing is completed, the second pressing plate assembly 2 moves in the reverse direction to reset, and at this time, the supporting block 18 keeps supporting the two glass plates.

[0056] After the second pressure plate assembly 2 is reset, the feeding of the third glass plate begins, the third glass plate enters the conveying mechanism, and the lifting mechanism lifts the third glass plate to make it separate from the conveying roller 6. Then, the telescopic drive cylinder 10 and the lifting drive cylinder 13 are reset, and the second pressure plate assembly 2 drives the first glass plate and the second glass plate that have been pressed to move toward the third glass plate until they have a set distance with the spacer strip of the third glass plate. Then, the telescopic drive cylinder 10 and the lifting drive cylinder 13 work together to move the inflatable member 14 to the bottom of the space between the second glass plate and the third glass plate, and make the support block 18 contact with the bottom surfaces of the three glass plates. At this time, the air supply mechanism works to inflate the space between the second glass plate and the third glass plate.

[0057] After the inflation is completed, the second pressure plate assembly 2 continues to move toward the first pressure plate assembly 1 to press the three glass plates together, the vacuum suction cup stops working, and the lifting mechanism drives the glass plate down until the glass plate falls to the conveying roller 6. The conveying roller 6 sends out the vacuum glass consisting of three glass plates that have been pressed together.

[0058] When the inflation device of the present embodiment is used, when the multiple glass plates that have been inflated and pressed are driven back by the second pressing plate assembly 2 to wait for the next glass plate to be fed, the support block 18 contacts the bottom surface of the glass plate, thereby supporting the glass plate and preventing the remaining glass plates except the glass plates fixed by the vacuum suction cup from falling. This is suitable for the inflation needs of hollow glass with three or more glass plates and heavier weight. Moreover, the device of the present embodiment only needs to fix the support block 18 on the surface of the inflation member 14 on the basis of the existing device, and there is no need to replace or modify the remaining structures, which makes the improvement of the entire device convenient and quick.
