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

[0031] Reference Figure 1 - Figure 3The utility model provides an embodiment: a vacuum device for producing foam boards, including a vacuum box 1, a placement box 2 is fixedly connected to the inner bottom wall of the vacuum box 1, a clamping base 8 is slidably connected inside the placement box 2, a clamping assembly is arranged inside the clamping base 8, a motor 3 is fixedly connected to the inner bottom wall of the placement box 2, a screw rod 4 is fixedly connected to the output end of the motor 3, two sliders 5 are threadedly connected to the outer side of the screw rod 4, the slider 5 is slidably connected to a slide rod 7, a rotating rod 6 is arranged between the clamping base 8 and the slider 5, a fixed block 23 is fixedly connected to the left part of the vacuum box 1, a vacuum pump 21 is fixedly connected to the left part of the fixed block 23, a derivation pipe 22 is fixedly connected to the left side of the vacuum pump 21, an air guide pipe 20 is fixedly connected to the top of the vacuum pump 21, and a sealing door 19 is rotatably connected to the front part of the vacuum box 1.

[0032] Specifically, first, the worker operates the driving turntable 13 to drive the screw rod 4 to rotate. This action causes the slider 5 to move, and then drives the rotating mechanism rotating rod 6. As the slider 5 moves, the clamping base 8 is adjusted up and down until a suitable position for placing the foam board is found and remains stable. When the foam board is accurately placed on the clamping base 8, the driving turntable 13 is started again to move it downward. This action will close the sealing door 19 to ensure the establishment of a vacuum environment. Subsequently, the vacuum pump 21 starts to work and extracts the air in the vacuum box 1 through the air guide tube 20 to form the required vacuum state. Finally, the air is discharged from the outlet pipe 22, and an ideal negative pressure environment is formed in the entire vacuum box 1, which is conducive to the foaming and curing of the foam material. In this process, the foam board can be formed under stable vacuum conditions, ensuring the quality and consistency of the product. When the foam board is formed, the system will automatically stop the vacuum pump 21 and start the subsequent non-vacuum stage to facilitate the workers to take out the finished product.

[0033] Reference Figure 2 and Figure 4 The clamping assembly includes two moving plates 10 and a second motor 14. The moving plate 10 is slidably connected to the inside of the clamping base 8. A second slide rod 11 is slidably connected to the inside of the moving plate 10. The second motor 14 is fixedly connected to the inner bottom wall of the clamping base 8. A turntable 13 is fixedly connected to the output end of the second motor 14. A connecting rod 12 is arranged between the second slide rod 11 and the turntable 13. A round table 15 is fixedly connected to the middle side of the top of the turntable 13. Two baffles 16 are fixedly connected to the bottom of the moving plate 10. A second screw rod 17 is threadedly connected to the inside of the baffle 16. Both ends of the second screw rod 17 are fixedly connected to pressure plates 18.

[0034] Specifically, after the foam board is formed, the motor 2 14 is started and the drive turntable 13 starts to rotate. This rotation acts on the connecting rod 12, causing the connecting rod 12 to rotate. The movement of the connecting rod 12 drives the movable plate 10 to move up and down along the slide rod 2 11. When the movable plate 10 moves to the appropriate position, that is, after confirming that the foam board has been firmly fixed in place, the motor 2 14 stops running. Then, the operation of twisting the pressure plate 18 located at the top of the screw rod 2 17 is implemented. The pressure plate 18 applies appropriate pressure through the precise adjustment of the screw rod to clamp the formed foam board. The key to this design is that in this way, it is ensured that the foam board will not slip due to slight movement or shaking during the subsequent lifting process, thereby effectively preventing possible damage to the board during the handling process.

[0035] Reference Figure 1 , Figure 3 and Figure 4 Both ends of the slide rod 11 are fixedly connected to the inside of the clamping base 8, one end of the connecting rod 12 is rotatably connected to the outer edge of the turntable 13, and the other end of the connecting rod 12 is rotatably connected to the bottom of the movable plate 10, the top of the round table 15 is rotatably connected to the inner top wall of the clamping base 8, one end of the rotating rod 6 is rotatably connected to the top of the slider 5, and the other end of the rotating rod 6 is rotatably connected to the bottom of the clamping base 8, both ends of the screw rod 4 are rotatably connected to the inside of the placement box 2, both ends of the slide rod 7 are rotatably connected to the inside of the placement box 2, two slide grooves 9 are provided inside the clamping base 8, and the right side of the air guide tube 20 is fixedly connected to the inside of the vacuum box 1.

[0036] Specifically, the sliding rod 11 serves as a bridge, and its two ends are respectively fixed inside the clamping base 8, ensuring the smooth movement of the moving plate 10. The connecting rod 12 plays a key transmission role, with one end connected to the turntable 13 to control the rotation of the entire device, and the other end connected to the moving plate 10 to ensure the accurate positioning of the foam board. The top of the round table 15 is connected to the inner top wall of the clamping base 8, providing a stable support point. The component rotating rod 6 is connected to the top of the slider 5 and the bottom of the clamping base 8 to ensure the rigidity and stability of the entire system. The screw rod 4 and the sliding rod 7 are both located inside the placement box 2, and they control the entry, exit and positioning of the foam board by precise rotation. The air duct 20 is fixed inside the vacuum box 1 to ensure the establishment and maintenance of the vacuum environment.

[0037] Working principle: During the production of foam board, the operator first drives the screw rod 14 to rotate by manipulating the driving turntable 13, thereby causing the slider 5 to move, and further links the rotating rod 6 to allow the clamping base 8 to move up and down accurately until the best placement position is found. After placing the board, the turntable 13 starts again, descends and closes the sealing door 19, and then the vacuum pump 21 starts to absorb the air in the vacuum box 1 and discharge it through the air guide 20 to complete the establishment of the vacuum environment and wait for the foam board to be cured. Once the molding is completed, the motor 2 14 intervenes to drive the turntable 13 to rotate, thereby driving the connecting rod 12 and guiding the moving plate 10 to move through the sliding rod 2 11. When the moving plate 10 is accurately in place, the motor 2 14 stops, and the operator will turn the pressing plate 18 on the screw rod 2 17 to accurately clamp the formed foam board to ensure that it will not slip during the subsequent lifting process, thereby protecting the foam board in all directions, avoiding potential damage, and ensuring the stability of product quality.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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 substitutions for some of the technical features therein.
