Description

Technical Field

[0001] This utility model belongs to the field of laminated glass production technology, specifically relating to a pre-pressing device for laminated glass. Background Technology

[0002] Laminated glass is a composite glass product made by bonding one or more layers of organic polymer interlayer (usually PVB) between two or more pieces of glass. After special pre-pressing (or vacuuming) and high-temperature and high-pressure processes, the glass and interlayer are bonded together.

[0003] Before laminated glass enters the reactor for high-temperature and high-pressure treatment, it needs to undergo pre-compression, which involves initially pressing the laminated glass. The laminated glass is placed on a pressure platform, and hydraulic equipment drives the extrusion plate downward to compress the laminated glass. However, most existing extrusion plates are flat, and when dealing with curved laminated glass, they need to be replaced with arc-shaped extrusion plates. At the same time, the arc angle of the arc-shaped extrusion plate is fixed and cannot be adjusted according to the surface of the curved laminated glass, which can lead to uneven compression or even damage to the laminated glass. To address these issues, a new pre-compression device for laminated glass is proposed. Utility Model Content

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in an embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0027] like Figure 1 , Figure 2 and Figure 3 This is a schematic diagram of the pre-pressing equipment for laminated glass in this embodiment. The pre-pressing equipment for laminated glass in this embodiment includes: a first mounting frame 1, a second mounting frame 2, a first electric push rod 3, and a linkage mechanism 4. The second mounting frame 2 is provided on one side of the first mounting frame 1. The first electric push rod 3 is provided between the first mounting frame 1 and the second mounting frame 2. The linkage mechanism 4 for pressing the laminated glass is provided below the first electric push rod 3. The linkage mechanism 4 includes a first transmission block 41, a second transmission block 42, a connecting block 43, and a pressure plate 44. The first transmission block 41 and the second transmission block 42 are symmetrically provided below the first electric push rod 3. Four connecting blocks 43 are equidistantly provided between the first transmission block 41 and the second transmission block 42. The first transmission block 41, the second transmission block 42, and the connecting blocks 43 are rotatably connected by rods. The pressure plate 44 is fixedly installed at the bottom of the first transmission block 41, the second transmission block 42, and the connecting blocks 43.

[0028] In this embodiment, when the laminated glass is located below the linkage mechanism 4, the moving end of the first electric push rod 3 extends, driving the linkage mechanism 4 to squeeze the laminated glass for pre-compression. When facing curved laminated glass, the first transmission block 41 and the second transmission block 42 move upward along the arc. The first transmission block 41, the second transmission block 42 and the linkage block 43 form an arc surface, which, together with the pressure plate 44, can squeeze the curved laminated glass, improving the functionality of the pre-compression equipment. When facing curved laminated glass, there is no need to replace the arc-shaped extrusion plate.

[0029] like Figure 4As shown, a drive mechanism 5 for adjusting the curvature of the linkage mechanism 4 is fixedly installed at the bottom end of the first electric push rod 3. The drive mechanism 5 includes a drive mounting shell 51, a first rotating rod 52, and a second rotating rod 53. The drive mounting shell 51 is fixedly installed at the bottom end of the first electric push rod 3. The first rotating rod 52 is rotatably connected to the second transmission block 42, and the second rotating rod 53 is rotatably connected to the first transmission block 41. The other end of the first rotating rod 52 is rotatably connected to the drive mounting shell 51, and the other end of the second rotating rod 53 is rotatably connected to the drive mounting shell 51. The first rotating rod 52 and the second rotating rod 53 are meshed with each other through gears.

[0030] In this embodiment, the first rotating rod 52 rotates on the side with the gear, driving the second rotating rod 53 to rotate. The side of the first rotating rod 52 near the second transmission block 42 moves upward along the arc, and the side of the second rotating rod 53 near the first transmission block 41 moves upward along the arc, changing the linkage mechanism 4 from a plane to a curved surface. The linkage mechanism 4 can adjust the angle of the curved surface according to the rotation amplitude of the first rotating rod 52, and can be adjusted according to the curvature of the curved laminated glass.

[0031] like Figure 5 As shown, the drive mechanism 5 also includes a linkage gear 54, a linkage rack 55, and a second electric push rod 56. The linkage gear 54 is fixedly installed at the other end of the first rotating rod 52. The linkage rack 55 is slidably installed on the inner wall of the drive mounting housing 51. The linkage rack 55 is meshed with the linkage gear 54. The second electric push rod 56 is fixedly installed on the inner wall of the drive mounting housing 51. The moving end of the second electric push rod 56 is fixedly connected to the top end of the linkage rack 55.

[0032] In this embodiment, the moving end of the second electric push rod 56, which drives the inner wall of the mounting shell 51, extends, causing the connecting rack 55 to move downward. The connecting rack 55 contacts the connecting gear 54, causing the first rotating rod 52 to rotate upward along the arc, adjusting the curvature of the connecting mechanism 4. The second electric push rod 56 retracts and resets, causing the connecting rack 55 to move upward. The connecting gear 54 controls the first rotating rod 52 to rotate downward along the arc, turning the connecting mechanism 4 back to a horizontal plane. This allows the connecting mechanism 4 to be switched between planar extrusion and curved extrusion.

[0033] like Figure 6As shown, a moving mechanism 6 for moving the first electric push rod 3 is mounted on the first mounting bracket 1 and the second mounting bracket 2. The moving mechanism 6 includes a moving base 61, a reciprocating lead screw 62, and a drive motor 63. The moving base 61 is fixedly mounted on the top of the first electric push rod 3. The reciprocating lead screw 62 is rotatably connected to the first mounting bracket 1 and the second mounting bracket 2. The reciprocating lead screw 62 is reciprocating (linearly) connected to the moving base 61. The drive motor 63 is fixedly mounted on the second mounting bracket 2, and the output shaft of the drive motor 63 is fixedly connected to one side of the reciprocating lead screw 62. Specifically, the reciprocating linear motion connection structure between the reciprocating lead screw 62 and the moving base 61 can adopt the existing lead screw and nut linear transmission structure. Specific details of this existing technology, which is not an improvement of this utility model, will not be elaborated upon.

[0034] In this embodiment, the output shaft of the drive motor 63 rotates, driving the reciprocating lead screw 62 to rotate. The reciprocating lead screw 62 controls the moving seat 61 to move to one side. When the moving seat 61 moves to one edge, it will automatically move to the other side, enabling automatic reciprocating movement. When facing laminated glass with a large area, it is convenient for the moving linkage mechanism 4 to perform all-round compression. At the same time, there is no need to adjust the rotation direction of the drive motor 63 to achieve the reciprocating movement effect, reducing the wear of the drive motor 63.

[0035] like Figure 6 As shown, the moving mechanism 6 also includes a partition plate 64. The partition plate 64 is symmetrically fixedly installed on the surface of the first mounting frame 1, and the other side of the partition plate 64 is fixedly connected to the surface of the second mounting frame 2. The two partition plates 64 form a guide groove.

[0036] In this embodiment, when the movable seat 61 reciprocates, it moves along the inner wall of the guide groove formed by the partition plate 64, ensuring that the movable seat 61 will not deviate during the movement, thus improving the stability of the movement of the movable seat 61.

[0037] like Figure 1 As shown, the first mounting bracket 1 consists of a support rod, a connecting rod, and a base, and the second mounting bracket 2 also consists of a support rod, a connecting rod, and a base. A connecting rod is provided between the two support rods, and the two ends of the connecting rod are fixedly connected to the support rods. A base is fixedly installed at the bottom of the support rod, and a rectangular groove is provided in the middle of the support rod.

[0038] In this embodiment, the support rod and the connecting rod are welded together to form a support frame. The base can increase the stability of the support frame. The groove design saves the material used to manufacture the support rod while ensuring that the strength of the support rod remains unchanged.

[0039] like Figure 3 and Figure 4As shown, circular limiting posts are symmetrically fixedly connected to the first transmission block 41, and circular limiting posts are symmetrically fixedly connected to the second transmission block 42. The circular limiting posts are rotatably connected to the first rotating rod 52 and the second rotating rod 53.

[0040] In this embodiment, the side of the first rotating rod 52 near the second transmission block 42 is limited, and the side of the second rotating rod 53 near the first transmission block 41 is limited, to prevent the first rotating rod 52 and the second rotating rod 53 from rotating and colliding with the rotating rods on the surfaces of the first transmission block 41, the second transmission block 42 and the connecting block 43.

[0041] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
