[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 - Figure 4 , the utility model provides an embodiment: a pressing machine for laminated glass, including a pressing machine housing 1, a vacuum mechanism is provided on the rear side of the pressing machine housing 1, the vacuum mechanism is used to extract the air inside the pressing machine housing 1, a cylinder 6 is fixedly connected to the inside of the pressing machine housing 1, a sealing door 8 is fixedly connected to the output end of the cylinder 6, a movable plate 7 is fixedly connected to the lower right side of the sealing door 8, a rotating block 11 is provided on the top of the movable plate 7, a motor 13 is fixedly connected to the inner bottom wall of the rotating block 11, a worm 14 is fixedly connected to the output end of the motor 13, a round table 22 is rotatably connected to the inside of the rotating block 11, and the bottom end of the round table 22 is fixedly connected There is a worm gear 12, which is meshed with the worm 14. A turntable 15 is fixedly connected to the middle part of the outer side of the frustum 22. Two clamping plates 18 are slidably connected inside the rotating block 11. A rotating rod 16 is provided between the turntable 15 and the clamping plate 18. A sliding rod 17 is slidably connected inside the clamping plate 18. A connecting block 19 is fixedly connected to the upper part of one side of the clamping plate 18. The connecting block 19 is threadedly connected to a screw rod 21. The bottom end of the screw rod 21 is fixedly connected to a clamping block 20. A plurality of heating elements 27 are provided on the inner bottom wall of the pressing machine chassis 1. The sealed door 8 is provided with a rotating mechanism, which is used to rotate the laminated glass.

[0032] Specifically, during operation, the driving cylinder 6 first drives the sealing door 8, the movable plate 7, and the support column 9 to move to the desired position and then stop. Next, the laminated glass is placed on the rotating block 11. At this time, the driving motor 13 is started, driving the worm 14 to rotate, and then driving the worm wheel 12, causing the round table 22 and the turntable 15 to operate. This series of actions further links the rotating rod 16, and the clamping plate 18 then slides along the outside of the slide rod 17 to achieve precise clamping of the laminated glass. According to the difference in glass thickness, by adjusting the screw rod 21, the clamping block 20 will move down accordingly to ensure that the glass is properly and evenly clamped. After clamping is completed, the glass is sent into the pressing machine housing 1 with the help of the driving cylinder 6, and the air in the housing is evacuated using the vacuum mechanism to create a vacuum environment. Subsequently, the rotating mechanism starts to operate, causing the laminated glass to rotate inside to ensure that it is heated evenly and avoid the generation of bubbles due to local overheating.

[0033] Reference Figure 4 The rotating mechanism includes a motor 23 and multiple bevel gears 26. The top of the bevel gear 26 is fixedly connected to the middle side of the bottom of the rotating block 11. One side of the motor 23 is fixedly connected to one side of the sealing door 8. The output end of the sealing door 8 is fixedly connected to a rotating rod 24. The outer side of the rotating rod 24 is fixedly connected to multiple bevel gears 1 25. The bevel gear 1 25 is meshed with the bevel gear 2 26.

[0034] Specifically, at this stage, the drive motor 23 starts running, and its power is transmitted to the rotating rod 24. The rotating rod 24 rotates accordingly, driving the bevel gear 1 25. As the bevel gear 1 25 rotates, the bevel gear 2 26 also rotates. This linkage effect continues to act on the rotating block 11, causing it to rotate. This continuous rotational motion ensures that the laminated glass can receive heat evenly. This uniform heating process helps prevent bubbles from being generated inside the laminated glass due to local overheating, thereby ensuring the quality and integrity of the final product. The entire process is designed to improve efficiency and reduce potential problems, and is a key link in the process flow.

[0035] Reference Figure 1 The vacuum mechanism includes a vacuum pump 2, one side of the vacuum pump 2 is arranged on the rear side of the pressing machine case 1, the top of the vacuum pump 2 is fixedly connected to an air suction pipe 3, and the left side of the vacuum pump 2 is fixedly connected to an air outlet pipe 4.

[0036] Specifically, the core component of the vacuum mechanism is the vacuum pump 2, which is mounted on the rear side of the press housing 1 to facilitate extraction of air from the interior. A suction pipe 3 is fixedly connected to the top of the vacuum pump 2. Its function is to guide external air into the vacuum pump 2 and draw the air in through the negative pressure mechanism inside the pump body.

[0037] At the other end of the suction pipe 3, that is, on the left side of the vacuum pump 2, there is a fixed outlet pipe 4. When the pump starts working, the suction pipe 3 introduces external air. After being processed by the vacuum pump 2, most of the air is extracted, forming a vacuum state. The outlet pipe 4 is responsible for discharging a small amount of gas inside the pump to maintain the normal operation of the system.

[0038] Reference Figure 1 - Figure 4 , a plurality of supporting legs 5 are fixedly connected to the bottom of the pressing machine case 1, two supporting columns 9 are fixedly connected to the bottom of the sealing door 8, and a pulley 10 is rotatably connected to the bottom of the support column 9. A controller 28 is provided on the front side of the pressing machine case 1, and the outer side of the movable plate 7 is slidably connected to the inner bottom wall of the pressing machine case 1. One end of the suction pipe 3 is fixedly connected to the rear side of the pressing machine case 1, and one end of the rotating rod 16 is rotatably connected to the clamping plate 18, and the other end of the rotating rod 16 is rotatably connected to the top edge of the turntable 15.

[0039] Specifically, the multiple support legs 5 at the bottom of the pressing machine housing 1 provide a stable foothold to ensure the stability of the equipment during use. The two support columns 9 at the bottom of the sealed door 8 are connected to the housing through a pulley 10, allowing the door to be opened and closed more flexibly and smoothly. The controller 28 is located on the front side of the pressing machine housing 1 and is responsible for monitoring and adjusting the operating parameters of the equipment to ensure the accuracy and safety of the operation. The movable plate 7 is designed to slide within the housing, making it easy to adjust its position to meet different work requirements. One end of the suction pipe 3 is fixed to the rear side of the housing for connecting to the vacuum pump 2 to ensure that the required vacuum environment can be formed in the housing. The rotating rod 16 is connected to the clamping plate 18 and the turntable 15. When the turntable 15 rotates, the rotating rod 16 drives the clamping plate to achieve the function of clamping and releasing the laminated glass.

[0040] Working principle: When in use, drive the cylinder 6, which in turn drives the sealing door 8, movable plate 7 and support column 9 and other components to move outward. When they move to the appropriate position, stop driving the cylinder 6. At this time, put the laminated glass on the rotating block 11. At this time, the driving motor 13 rotates, which in turn drives the worm 14 to rotate, which in turn drives the worm gear 12 to rotate, thereby driving the round table 22 and the turntable 15 to rotate, and then drives the rotating rod 16 to rotate, and then pulls the clamping plate 18 to slide on the outside of the slide rod 17, thereby clamping the laminated glass. At this time, according to the thickness of the laminated glass, twist the screw 21, which in turn drives the clamping block 20 to move downward, thereby clamping the laminated glass. After that, it is sent into the interior of the pressing machine housing 1 by driving the cylinder 6. At this time, the air inside the pressing machine housing 1 is sucked out by the vacuum mechanism to achieve a vacuum environment. At this time, the laminated glass is heated by the heating element 27. As the temperature rises, the laminated glass begins to fuse with the inner layer of colloid. After a period of heating, the laminated glass and the colloid are completely fused, and the laminated glass is pressed. At this time, the driving motor 23 drives the rotating rod 24 to rotate, and then drives the bevel gear 1 25 to rotate, so that the bevel gear 26 and the rotating block 11 rotate, and then the laminated glass rotates, so as to achieve uniform heating and avoid bubbles in the laminated glass.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
