Description

Technical Field

[0001] The invention relates to the technical field of glass production, and in particular to a servo flat press for producing laminated glass. Background Art

[0002] Laminated glass, a composite glass product offering high safety, sound insulation, and light transmittance, is widely used in architectural curtain walls, automotive windshields, high-speed rail windows, and other applications. During its production, the flat pressing process is a critical step in ensuring a tight fit between the glass and the interlayer (such as PVB film) and eliminating bubbles and gaps. During the flat pressing process, the upper and lower rollers of the flat press apply uniform and controllable pressure to the laminated glass, allowing the interlayer to fully melt and bond to the glass surface, either under heating or at room temperature. This ensures the laminated glass's mechanical properties and service life.

[0003] Existing flat presses mostly use a single extrusion mode, which makes it difficult to completely remove the air inside the laminated glass, and is prone to problems such as bubbles and loose bonding. Especially for laminated glass with thicker thickness or special specifications, the extrusion force and frequency are insufficient, affecting the stability of product quality. In addition, the pressure and action frequency of the upper and lower pressing rollers are fixed, and it is difficult to flexibly adjust according to parameters such as the thickness of the laminated glass and the material of the intermediate film. As a result, some laminated glass still has problems such as bubbles and partial non-bonding after flat pressing, affecting product quality. Summary of the Invention

[0023] It should be noted that a partition column is provided in the middle of the reciprocating screw rod 602, and two sets of symmetrically arranged reciprocating threads are provided on the partition column, and the surfaces of the two sets of symmetrical reciprocating threads are both threadedly connected to the connecting rod 603, so that the two connecting rods 603 can move back and forth relative to each other.

[0024] Preferably, in the present invention, the upper pressing roller 3 is connected to the interior of the limit block 50 in a sliding and rotating manner, and is rotatably supported in the middle of the support block 52; Two auxiliary sliding grooves are provided on both sides of the middle sliding groove of the positioning plate 12 to provide stable guidance for the sliding of the positioning block 605.

[0025] It should be noted that the length of the sliding groove in the middle of the positioning plate 12 is greater than the length of the fixing block 609 to avoid interference during the movement of the fixing block 609.

[0026] Preferably, in the present invention, the secondary extrusion mechanism 6 is connected to a pushing mechanism 7, which can adjust the stroke and frequency of the up and down movement of the push rod 608; Preferably, the pushing mechanism 7 in the present invention includes: a small motor 2 702 fixed to the side of the support plate 604 and having an output end fixedly connected to an output shaft 707; The output shaft 707 is rotatably supported in the middle of the support plate 604; A connecting plate 701 is fixedly connected to the other end of the output shaft 707 and is fixedly connected to the rotating drum 700 via a connecting column on the side; A micro motor 704 is embedded in the drum 700 and has an output end fixedly connected to the threaded rod 705; A slide plate 706 is threadedly sleeved on the surface of the threaded rod 705 and slidably embedded in the slide groove of the rotating drum 700; A pushing block 703 is slidably disposed inside the rotating drum 700 and fixedly connected to one side of the sliding plate 706 .

[0027] Preferably, in the present invention, there are four push blocks 703 and they are arranged circumferentially; The two output ends of the micro motor 704 are fixed with symmetrically distributed threaded rods 705, and the surfaces of the threaded rods 705 are threadedly connected to the slide 706; There are two groups of micro motors 704, threaded rods 705 and slides 706, and each group is connected to two oppositely distributed push blocks 703 through the slide 706; The two groups are arranged in a cross pattern, one group is located on one side of the rotating drum 700, and the other group is located on the other side of the rotating drum 700; cross-shaped sliding grooves are provided on both sides of the rotating drum 700.

[0028] It should be noted that the micro motor 704 is a dual-output motor to facilitate driving the threaded rods 705 on both sides.

[0029] Preferably, in the present invention, the upper pressure roller 3 is fixedly connected to the output end of the upper roller output motor 10, and the upper roller output motor 10 is fixedly mounted on one side surface of the support block 52; The positioning plate 12 is slidably connected to the inner surface of the limiting slide rail 43; The lower pressure roller 2 is fixedly connected to the output end of the lower roller output motor 9 , and the lower roller output motor 9 is fixedly mounted on a side plate at one end of the middle portion of the frame 1 .

[0030] It should be noted that the outer layer where the upper pressing roller 3 and the lower pressing roller 2 come into contact is made of a flexible material to avoid causing damage to the laminated glass.

[0031] During the implementation process, when the laminated glass moves to the gap between the lower pressing roller 2 and the upper pressing roller 3, the lower roller output motor 9 and the upper roller output motor 10 are set to drive the lower pressing roller 2 and the upper pressing roller 3 to rotate respectively, so that the upper pressing roller 3 rotates and rolls on both sides of the laminated glass; When the upper pressure roller 3 rotates, a small motor 2 702 is set. The output end of the small motor 2 702 rotates along the middle of the support plate 604 with the output shaft 707. The output shaft 707 rotates with the connecting disk 701. The connecting disk 701 rotates with the rotating drum 700 and the pushing block 703. The pushing block 703 rotates to push the push plate 607. The push plate 607 is pushed downward by the pushing block 703. The push plate 607 moves downward with the push rod 608, the fixed block 609, and the ball 610 along the slide groove in the middle of the positioning plate 12 to push the upper pressure roller 3. The upper pressure roller 3 moves with the upper roller output motor 10 downward along the middle of the limit block 50 to push the support block 52. The support block 52 pushes the telescopic column 53 and the spring 1 54 along the slide groove inside the limit block 50, so that the upper pressure roller 3 rotates and squeezes the laminated glass for the second time. The push plate 607 rotates with the rotating drum 700 and is lifted up by the reverse thrust of the spring 2 606. The push rod 608 can rotate with the rotating drum 700 to move up and down along the slide groove in the middle of the positioning plate 12 with the fixed block 609 and the ball 610, and push the upper pressure roller 3 back and forth to achieve multiple and multi-level crushing. When it is necessary to adjust the reciprocating frequency and stroke of the push rod 608, the fixed block 609, and the ball 610, one of the micro motors 704 is set. One of the micro motors 704 drives the threaded rods 705 on both sides to rotate. The rotation of the threaded rods 705 causes the slides 706 on the surface to move along the chute on one side of the rotating drum 700 and be stored in the rotating drum 700, thereby reducing the amount of the pushing block 703 extending to achieve the adjustment of the pushing frequency. One group of micro motors 704 is set, and one group of micro motors 704 drives the threaded rods 705 on both sides to rotate. The rotation of the threaded rods 705 causes the slides 706 on the surface to move along the slide groove on one side of the rotating drum 700 with the pushing blocks 703, thereby adjusting the extension length of the pushing blocks 703 and adjusting the overall stroke of the push rod 608, the fixed block 609 and the ball 610.

[0032] Example 2 It shows another embodiment of the present invention based on the first embodiment, so the repeated parts will not be described again.

[0033] Preferably in the present invention, two sets of height adjustment mechanisms 4 are connected to both sides of the positioning plate 12 for adjusting the gap between the upper pressing roller 3 and the lower pressing roller 2 .

[0034] Preferably, in the present invention, the height adjustment mechanism 4 comprises: two limiting slide rails 43 fixedly connected to the inner side of the slide groove in the middle of one end of the frame 1; A reduction motor 40 fixed to the top of the frame 1, with the output end fixed to the threaded column 41; A connecting block 42 has a middle portion at one end threadedly sleeved on the surface of the threaded column 41 and the other end fixedly connected to the surface of the positioning plate 12 .

[0035] Implementation process: When the distance between the upper pressing roller 3 and the lower pressing roller 2 needs to be adjusted, a reduction motor 40 is provided. The output end of the reduction motor 40 drives the threaded column 41 to rotate. The rotation of the threaded column 41 causes the connecting block 42 to move the positioning plate 12 upward or downward along the limiting slide rail 43 for adjustment. The positioning plate 12 moves upward or downward with the limiting blocks 50 on both sides, the upper pressure roller 3 and the upper roller output motor 10 for adjustment.

[0036] Example 3 It shows another embodiment of the present invention based on the first and second embodiments, so the repeated parts will not be described again.

[0037] Preferably in the present invention, a middle plate 11 is fixed to the middle portion of the inner side of the frame 1 , and a conveying mechanism 8 is mounted on the middle plate 11 for conveying the laminated glass.

[0038] Preferably, in the present invention, the conveying mechanism 8 comprises: a large motor 80 fixedly mounted on the side plate at the other end of the middle portion of the frame 1; A transmission shaft 81 is fixedly connected to the output end of the large motor 80 and has a bevel gear 1 82 fixedly connected to the surface thereof, wherein the bevel gear 1 82 and the bevel gear 2 83 are meshed with each other; A rotating shaft 84 fixed to the middle of the second bevel gear 83 and having at least two conveying wheels 86 fixed to its surface; The limiting plates 85 are symmetrically distributed on both sides of the conveying wheel 86 and fixed to the surface of the middle plate 11 . The rotating shaft 84 is rotatably supported in the middle of the limiting plates 85 .

[0039] It should be noted that the material of the conveying wheel 86 is rubber material, which makes it easier to convey the laminated glass forward; The large motor 80 is a dual-output motor, and both ends of the large motor 80 are fixedly connected to a transmission shaft 81; The top height of the conveying wheel 86 is the same as the top height of the lower pressing roller 2 to ensure synchronous conveying.

[0040] During the implementation process, the laminated glass is placed on the surface of multiple horizontally arranged conveying wheels 86, and a large motor 80 is set. The output end of the large motor 80 drives the transmission shafts 81 on both sides to rotate, and the transmission shafts 81 drive the bevel gear 1 82 and the bevel gear 2 83 to rotate. The bevel gear 2 83 drives the rotating shaft 84 and the conveying wheel 86 to rotate along the middle of the limiting plate 85. The conveying wheel 86 rotates to realize the conveyance of the laminated glass, so that the laminated glass moves to the surface of the lower pressure roller 2.

[0041] It should be noted that the electrical components in this application are all electrically connected and remotely coordinated and controlled through wireless signal transmission via an external controller (not shown).
