Description

Technical Field

[0001] This utility model relates to the field of photocatalytic composite processing technology, specifically to a vacuum-assisted lamination device for photocatalytic composite. Background Technology

[0002] Composite photocatalysts are made of nanocomposite materials, which completely solves the problem that photocatalysts must be exposed to ultraviolet light to function. They powerfully and persistently decompose harmful gases such as formaldehyde, benzene, ammonia, and TVOC, as well as various odors, oxidizing and decomposing them into harmless carbon dioxide and water. Composite photocatalysts can continuously release negative oxygen ions, making the air feel fresh and comfortable. They also have decomposition functions that activated carbon does not have, and can effectively decompose and remove various odors such as smoke, hydrogen sulfide, and ammonia in the room.

[0003] In the production process of photocatalytic composite materials, different layer structures need to be laminated to form a complete photocatalytic composite material. If the pressure distribution of the laminator is uneven or the temperature control is inaccurate during the pressing process of the photocatalytic composite material, the laminator may cause uneven lamination of the photocatalytic composite material, resulting in quality problems such as bubbles and delamination. Therefore, it is particularly important to design a new vacuum-assisted lamination device for photocatalytic composite to solve the above-mentioned technical defects and improve the practicality of the overall lamination device.

[0007] The connecting assembly is used to connect the connecting tube and the vacuum tube. The connecting assembly includes a fixed tube, and multiple sets of filter screens are fixedly connected inside the fixed tube. A rotating cylinder is rotatably connected to one end of the vacuum tube and the connecting tube near the fixed tube. Limit sleeves are fixedly connected to both ends of the fixed tube near the two sets of rotating cylinders. An annular limit block is fixedly connected to one end of the rotating cylinder near the limit sleeve.

[0008] The cooling device is used to cool the vacuum tube.

[0009] As a preferred embodiment of this utility model, threaded grooves are provided on both the outer side of the limiting sleeve and the inner side of the rotating cylinder, and the two sets of threaded grooves are threadedly connected to each other.

[0010] As a preferred embodiment of this utility model, the limiting sleeve and the annular limiting block are mutually limitingly connected, and a compression ring is slidably connected to the inner side of the limiting sleeve.

[0014] As a preferred embodiment of this utility model, sealing strips are provided on the outer side of the support platform and the inner side of the connecting platform, and the support platform and the connecting platform are respectively connected to the two sets of sealing strips through multiple sets of elastic compression blocks.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, the connecting component is designed to securely and sealably connect the connecting tube and the vacuum tube. This component includes a fixed tube, a filter screen, a rotating cylinder, a limiting sleeve, and an annular limiting block. Multiple sets of filter screens are installed inside the fixed tube to filter impurities that may enter the vacuum system. A rotating cylinder is rotatably connected to one end of both the vacuum tube and the connecting tube near the fixed tube, while limiting sleeves are fixedly connected to both ends of the fixed tube. An annular limiting block is fixed to one end of the rotating cylinder near the limiting sleeve, and the limiting sleeve and the annular limiting block are mutually limitingly connected to ensure that the rotating cylinder will not detach from the fixed tube. Furthermore, threaded grooves are provided on the inner and outer sides of both the limiting sleeve and the rotating cylinder, achieving a tight connection through threaded connection. The threaded connection and limiting design ensure a secure and reliable connection between the vacuum tube and the connecting tube, preventing loosening. The cooperation between the annular limiting block and the limiting sleeve, as well as the inclusion of a compression ring and a sealing ring, enhance the sealing performance of the connection, prevent gas leakage, and ensure the effective operation of the vacuum system. When cleaning or replacing the filter screen is required, the fixed tube can be easily disassembled by releasing the threaded connection, facilitating maintenance.

[0017] 2. In this utility model, the cooling device is designed to cool the vacuum tube, preventing condensation of substances inside the tube or affecting the performance of the vacuum pump due to high temperatures. The component includes a spiral tube, a water pump, a connecting cylinder, a thermoelectric cooler, and heat sinks. The spiral tube is tightly wound around the outside of the vacuum tube, with its two ends connected to the water pump and the connecting cylinder, respectively. The water pump draws coolant from the connecting cylinder, which then flows back to the connecting cylinder after passing through the spiral tube, forming a circulation. The thermoelectric cooler is attached to the outside of the connecting cylinder, lowering the temperature of the coolant through cooling. The heat sink helps dissipate the heat generated by the thermoelectric cooler. Through the circulation of the spiral tube and coolant, and the cooling treatment of the coolant, the temperature of the vacuum tube is effectively reduced, preventing condensation and lowering the temperature inside the vacuum tube. This reduces the risk of condensation or vaporization caused by high temperatures, thus protecting the vacuum pump from damage.

[0018] 3. In this utility model, the sealing strip is designed to enhance the sealing between the pressure plate and the connecting platform, preventing gas leakage from affecting the vacuum effect. The sealing strip is respectively set on the outer side of the support platform and the inner side of the connecting platform. Multiple sets of elastic compression blocks contact the pressure plate and generate a compression action, thereby achieving the sealing effect. Through the action of the elastic compression blocks, the sealing strip can tightly fit the inner and outer sides of the pressure plate, effectively preventing gas leakage. Enhancing the sealing performance helps to improve the vacuum degree of the vacuum system, thereby improving the lamination effect.

[0019] 4. In this utility model, through the design of the vacuum system, the gas and impurities in the photocatalyst composite material are effectively removed by the vacuuming operation, the bonding strength of the lamination interface is improved, and the bubbles and delamination are reduced, thereby improving the lamination quality.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] Please see Figures 1-5 This utility model provides a technical solution:

[0029] A vacuum-assisted lamination device for photocatalytic composite includes a laminator body 1, a pressure plate 2 slidably connected inside the laminator body 1, a connecting platform 3 fixedly connected inside the laminator body 1 and below the pressure plate 2, a vacuum tube 4 fixedly connected to the bottom of the connecting platform 3, a connecting pipe 5 provided at the end of the vacuum tube 4 away from the connecting platform 3, a connecting component 6 provided at the end of the connecting pipe 5 close to the vacuum tube 4, and a cooling device 7 provided on the outside of the vacuum tube 4.

[0030] The connecting component 6 is used to connect the connecting tube 5 to the vacuum tube 4. The connecting component 6 includes a fixed tube 8. Multiple sets of filter screens 9 are fixedly connected inside the fixed tube 8. The vacuum tube 4 and the connecting tube 5 are rotatably connected to the ends of the fixed tube 8. The fixed tube 8 is fixedly connected to the two sets of rotating tubes 10 at both ends. The rotating tube 10 is fixedly connected to the end of the rotating tube 10 near the limit sleeve 11 with an annular limit block 12.

[0031] The cooling device 7 is used to cool the vacuum tube 4.

[0032] Furthermore, threaded grooves 13 are provided on the outer side of the limiting sleeve 11 and the inner side of the rotating cylinder 10. The two sets of threaded grooves 13 are threaded together, so that the rotating cylinder 10 can be connected to the fixed pipe 8, thereby allowing the vacuum tube 4 to be connected to the connecting pipe 5. The connecting pipe 5 is connected to the vacuum pump, and together with the fixed pipe 8, a negative pressure is generated inside the vacuum tube 4.

[0033] The limiting sleeve 11 and the annular limiting block 12 are mutually limitingly connected. The inner side of the limiting sleeve 11 is slidably connected to the compression ring 14. The end of the compression ring 14 near the fixed tube 8 is fixedly connected to the sealing ring 15. The annular limiting block 12 is connected to the limiting sleeve 11. The limiting sleeve 11, in conjunction with two sets of threaded grooves 13, makes the rotating cylinder 10 and the fixed tube 8 limitingly connected. At the same time, when the annular limiting block 12 is connected to the limiting sleeve 11, the annular limiting block 12 drives the compression ring 14 to move, so that the compression ring 14 squeezes the sealing ring 15. When the vacuum tube 4 and the connecting tube 5 are connected to the fixed tube 8, the sealing performance of the connection between the vacuum tube 4 and the connecting tube 5 and the fixed tube 8 can be increased to prevent gas leakage and affect the vacuuming effect.

[0034] Secondly, the cooling device 7 includes a spiral tube 16 fixedly connected to the outside of the vacuum tube 4. A water pump 17 and a connecting cylinder 18 are fixedly connected to both ends of the spiral tube 16, respectively. The end of the water pump 17 away from the spiral tube 16 extends into the interior of the connecting cylinder 18. A semiconductor cooling chip 19 is fixedly connected to the outside of the connecting cylinder 18. A heat sink is fixedly connected to the outside of the semiconductor cooling chip 19. The connecting cylinder 18 is fixedly connected to the laminator body 1. When vacuuming, the cooling device 7 can cool the vacuum tube 4, thereby cooling the material introduced into the vacuum tube 4. As the temperature decreases, the material forms gel-like particles, which are easily filtered by multiple sets of filter screens 9 to prevent them from entering the vacuum pump and affecting its operation.

[0035] Furthermore, a support platform 20 is fixedly connected inside the connecting platform 3. The support platform 20 has multiple sets of through holes 21 inside, which are interconnected with the vacuum tube 4. When a negative pressure is generated inside the vacuum tube 4, the pressure plate 2 is connected to the connecting platform 3, and the negative pressure is generated inside the support platform 20 through the multiple sets of through holes 21 to perform vacuuming.

[0036] Furthermore, sealing strips 22 are provided on the outer side of the support platform 20 and the inner side of the connecting platform 3. The support platform 20 and the connecting platform 3 are connected to the two sets of sealing strips 22 respectively through multiple sets of elastic compression blocks 23. When the pressure plate 2 is connected to the connecting platform 3, the pressure plate 2 comes into contact with the two sets of sealing strips 22. The multiple sets of elastic compression blocks 23 drive the sealing strips 22 to move, so that the sealing strips 22 can fit the inner and outer sides of the pressure plate 2, increasing the sealing performance of the connection between the pressure plate 2 and the connecting platform 3 and preventing the vacuuming effect from being affected.

[0037] In this embodiment, the specific implementation scenario is as follows: In actual use, the photocatalyst composite material is placed inside the support platform 20, and the pressure plate 2 is brought into contact with the connecting platform 3. When the pressure plate 2 is connected to the connecting platform 3, the pressure plate 2 comes into contact with two sets of sealing strips 22. Multiple sets of elastic compression blocks 23 drive the sealing strips 22 to move, so that the sealing strips 22 can fit the inner and outer sides of the pressure plate 2, increasing the sealing performance of the connection between the pressure plate 2 and the connecting platform 3 and preventing any impact on the vacuuming effect. The two sets of threaded grooves 13 are threaded together, so that the rotating cylinder 10 can connect with the fixed tube. 8. Connect the vacuum tube 4 to the connecting tube 5. Connect the annular limiting block 12 to the limiting sleeve 11. The limiting sleeve 11, in conjunction with two sets of threaded grooves 13, limits the connection between the rotating cylinder 10 and the fixed tube 8. Simultaneously, when the annular limiting block 12 is connected to the limiting sleeve 11, the annular limiting block 12 causes the compression ring 14 to shift, causing the compression ring 14 to compress the sealing ring 15. This increases the sealing performance of the connection between the vacuum tube 4, connecting tube 5, and fixed tube 8, preventing leakage. The gas leakage affects the vacuuming effect. The vacuum pump is started, and through the connecting pipe 5 and the fixed pipe 8, a negative pressure is generated inside the vacuum tube 4. When a negative pressure is generated inside the vacuum tube 4, the pressure plate 2 connects to the connecting platform 3, and through multiple sets of through holes 21, a negative pressure is generated inside the support platform 20 for vacuuming. The semiconductor cooling chip 19 is started, and its cooling end cools the coolant inside the connecting cylinder 18. The water pump 17 is started, introducing coolant into the spiral tube 16, enabling the spiral tube 16 to cool the coolant. The vacuum tube 4 is cooled, causing the material introduced into the vacuum tube 4 to cool down and form gel-like particles as the temperature decreases. This facilitates filtration by multiple filter screens 9, preventing the material from entering the vacuum pump and affecting its operation. When cleaning and maintenance of the multiple filter screens 9 are required, the design of the connecting component 6 allows the fixing tube 8 to be detached from the vacuum tube 4 and the connecting tube 5, making it convenient to clean and maintain the filter screens 9. Compared with existing lamination devices, this invention improves the overall practicality of the lamination device through its design.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
