Description

Technical Field

[0001] This utility model relates to the technical field of MOFs multifunctional membrane coating, specifically a high-efficiency MOFs multifunctional membrane coating machine. Background Technology

[0002] MOFs (Multifunctional Metal-Organic Fabrics) membranes are highly ordered porous materials composed of metal ions and organic ligands, exhibiting excellent gas adsorption, separation, and catalytic properties. In the manufacturing process of MOFs, the coating machine plays a crucial role. However, existing high-efficiency coating machines still have certain shortcomings in use. Specifically, conventional coating machines typically require removing the old rotating shaft and then removing and reinstalling the new one during the feeding process. This process is cumbersome and time-consuming, resulting in poor continuity of feeding and affecting production efficiency and the stability of continuous operation.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent with announcement number CN218287197U, announcement date January 13, 2023) provides a high-efficiency multi-functional film coating machine, including a machine body and a printer. The printer is fixedly installed at the rear of the machine body. A rotating feeder, a motor, and a guide seat are provided on the rear side of the printer. The rotating feeder is fixedly connected to the printer, and the motor is fixedly connected to the rotating feeder. The guide seat is located on the rear side of the rotating feeder. The lower ends of the machine body, printer, rotating feeder, and guide seat are all fixedly installed to the ground. The rotating feeder includes a guide seat, a rotating frame, a stop, a support leg, and a rotating rod. A bearing is provided on the side of the rotating rod. The guide seat is fixedly connected to the support leg. The rotating frame is rotatably installed in the middle of the guide seat. In this invention, the motor drives the rotating feeder to rotate and pour the film roll onto the guide seat. Then, the guide seat guides the film roll to the rear, while the rotating rod at the bottom turns to the front to prepare for feeding the printer, thus facilitating automatic feeding.

[0004] While existing technologies enable automatic unloading of film rolls via a guide seat, the rotating unloading frame, rotating rod, and guide seat require precise alignment and stable operation during operation, increasing the complexity and cost of equipment maintenance. Furthermore, the insufficient fixing of the coating structure and the lack of control precision during the coating process can easily lead to uneven coating surfaces, resulting in significant differences in film thickness and affecting the quality of the final product.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing MOFs multifunctional membrane high-efficiency coating machine. Therefore, we proposed that the MOFs multifunctional membrane high-efficiency coating machine can effectively solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a high-efficiency MOFs multifunctional film coating machine to solve the problems mentioned in the background art. Currently, the automatic unloading of film rolls is achieved through a guide seat, but during operation, the rotating unloading frame, rotating rod and guide seat need to be precisely aligned and run stably, which increases the complexity and cost of equipment maintenance. In addition, the fixed setting of the coating structure and the insufficient control precision during the coating process can easily lead to uneven coating surface, resulting in significant differences in film thickness and affecting the quality of the final product.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency MOFs multifunctional membrane coating machine, comprising a conveying structure, a frame mounted on the conveying structure, a storage tank for storing solutions mounted on the side of the conveying structure, a delivery pump mounted on the side of the storage tank, the input end of the delivery pump being connected to the inside of the storage tank via a pipe, the output end of the delivery pump being connected to a glue head via a first pipe, the glue head being located at the bottom of the frame, a protective plate being provided at the bottom of the glue head, a telescopic cylinder being installed inside the frame, a scraper being connected to the bottom of the telescopic cylinder, and the glue head and scraper being located directly above the conveying structure.

[0008] Preferably, the storage tank is equipped with a stirring assembly, which includes a motor mounted on the storage tank. The output end of the motor is connected to a rotating shaft, which extends through into the interior of the storage tank, and a stirring element is mounted on the outside of the rotating shaft.

[0009] Preferably, the storage box is equipped with a heating tube.

[0010] Preferably, a cleaning component is provided under the conveying structure. The cleaning component includes a support base installed at the bottom of the conveying structure. A cleaning roller and a cleaning seat are installed on the support base. The cleaning roller is located at the upper end of the cleaning seat, and an arc groove adapted to the cleaning roller is formed on the upper surface of the cleaning seat.

[0011] Preferably, a conveying assembly is provided under the conveying structure, the conveying assembly including a fan installed under the conveying structure, and the input end of the fan is connected to a second pipe.

[0012] Preferably, an insulated box is fitted outside the storage box, and the end of the second pipe is connected through the inside of the insulated box.

[0013] Preferably, the blower output end is connected to the inner cavity of the cleaning seat through a third pipe, and the cleaning seat has a through hole.

[0014] Preferably, a drying box is connected to the third pipe via a fourth pipe, and the drying box is installed under the frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This MOFs multifunctional membrane high-efficiency coating machine uses a conveying structure to continuously move the substrate to be coated along a set path, avoiding the time waste of intermittent operation. Furthermore, it facilitates the overall transport of the film roll, reducing the problem of increased maintenance costs caused by complex structures. A telescopic cylinder drives the scraper to move up and down, adjusting its distance from the substrate surface, thereby controlling the coating thickness and improving film quality. The specific details are as follows: The conveying structure drives the substrate to move continuously, which not only significantly shortens the production cycle of a single batch and significantly increases the output per unit time, but also reduces energy waste and equipment wear caused by frequent start-ups and shutdowns, providing a stable guarantee for efficient mass production. The overall structure facilitates the transport of film rolls and reduces the problem of increased maintenance costs caused by complex structures.

[0016] The telescopic cylinder inside the frame drives the scraper to move up and down, which can precisely adjust the distance between the scraper and the substrate surface, thereby flexibly controlling the coating thickness. The versatility greatly improves the equipment's adaptability to a variety of products, reduces the cost of equipment modification and debugging for different products, and enhances production flexibility.

[0017] The motor-driven stirring unit continuously stirs the MOFs solution in the storage tank, which can effectively prevent MOFs particles from settling and ensure uniform solution composition. The heating tube and the heat preservation box work together to achieve precise control of solution temperature, optimize solution flow and adhesion, and improve product qualification rate and performance.

[0018] The cleaning component below the conveyor structure removes surface dust through cleaning rollers. The arc groove design of the cleaning seat self-cleans the cleaning rollers and prevents secondary pollution. The fan utilizes the residual heat of the insulation box and sprays hot air through the through holes to enhance the cleaning effect, reduce the scrap rate caused by pollution, and ensure continuous and stable production.

[0019] The fan transports the waste heat gas in the insulation box to the cleaning seat through the third pipe for cleaning the cleaning roller. At the same time, some of the waste heat enters the drying box through the fourth pipe to accelerate the drying of the coating layer. The waste heat recovery method reduces the consumption of additional heating energy and can also shorten the drying time. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: In this example, the telescopic cylinder 8 inside the frame 2 drives the scraper 9 to move up and down, adjusting its distance from the substrate surface, thereby controlling the coating thickness. By flexibly adjusting the spacing of the scraper 9, the production requirements of MOFs films of different thicknesses can be met, such as... Figures 1-4The technical solution shown includes a conveying structure 1, a frame 2 mounted on the conveying structure 1, a storage tank 3 for storing the solution mounted on the side of the conveying structure 1, a delivery pump 4 mounted on the side of the storage tank 3, the input end of the delivery pump 4 being connected to the inside of the storage tank 3 via a pipe, and the output end of the delivery pump 4 being connected to a glue head 6 via a first pipe 5. The glue head 6 is located at the bottom of the frame 2, and a protective plate 7 is provided at the bottom of the glue head 6. A telescopic cylinder 8 is installed inside the frame 2, and a scraper 9 is connected to the bottom of the telescopic cylinder 8. The glue head 6 and the scraper 9 are located directly above the conveying structure 1. The conveying structure 1 will drive the substrate to be coated to move continuously along a set path, avoiding the time waste of intermittent operation, and facilitating the overall transport of the film roll, reducing the problem of increased maintenance costs caused by complex structures. The storage tank 3 is used to store the MOFs solution to be coated. The delivery pump 4 is started, and the delivery pump 4 draws MOFs solution from the storage tank 3 through the input end pipe and delivers it to the glue head 6 through the first pipe 5. The glue head 6 evenly applies the solution onto the moving substrate surface on the delivery structure 1. The protective plate 7 at the bottom of the glue head 6 can prevent solution splashing, protect the surrounding structure, and reduce the workload of subsequent cleaning and maintenance. After the initial coating, the substrate continues to move under the scraper 9. The telescopic cylinder 8 inside the frame 2 drives the scraper 9 to move up and down, adjusting its distance from the substrate surface, thereby controlling the coating thickness. By flexibly adjusting the distance of the scraper 9, the production needs of MOFs films of different thicknesses can be met, improving the versatility of the equipment and its adaptability to diverse products. When the substrate passes through the scraper 9, the scraper 9 scrapes off the excess MOFs solution on the surface, making the coating thickness uniform and the surface smooth, thus improving the quality of the film layer.

[0024] Example 2: In this example, the heating tube 12 inside the storage tank 3 can heat the solution, and together with the insulation box 18, it can achieve precise temperature control of the solution, ensuring the coating effect. Precise temperature control can optimize the fluidity and adhesion of the MOFs solution, specifically as follows: Figures 3-6As shown, a stirring assembly is installed on the storage tank 3. The stirring assembly includes a motor 10 mounted on the storage tank 3. The output end of the motor 10 is connected to a rotating shaft, which extends through into the interior of the storage tank 3. A stirring element 11 is installed on the outside of the rotating shaft. A heating tube 12 is installed inside the storage tank 3. A cleaning assembly is installed below the conveying structure 1. The cleaning assembly includes a support base 13 installed at the bottom of the conveying structure 1. A cleaning roller 14 and a cleaning seat 15 are installed on the support base 13. The cleaning roller 14 is located above the cleaning seat 15, and an arc groove adapted to the cleaning roller 14 is opened on the upper surface of the cleaning seat 15. When the motor 10 is turned on, the motor 10 drives the rotating shaft and the stirring element 11 on the outside to rotate, continuously stirring the MOFs solution in the storage tank 3, preventing the MOFs particles in the solution from settling, ensuring the uniformity of the solution, and improving the stability of product quality. The heating tube 12 inside the storage tank 3 can heat the solution. Heating is performed, and the solution temperature is precisely controlled in conjunction with the heat preservation box 18 to ensure the coating effect. Precise temperature control can optimize the fluidity and adhesion of MOFs solution, making the solution easier to spread on the substrate surface and reducing coating defects. After the substrate coating operation is completed, the conveying structure 1 continues to rotate, and the cleaning component below it cleans the surface of the conveying structure 1. The cleaning roller 14 contacts the lower surface of the conveying structure 1 and removes surface dust during the rolling process. Timely cleaning of the conveying structure 1 can prevent residual MOFs solution or impurities from affecting the coating quality of the next batch of substrates, ensuring the continuity of production and the consistency of products. The cleaning seat 15 on the support 13 facilitates the cleaning of the surface of the cleaning roller 14. Since the arc groove on the cleaning seat 15 is adapted to the cleaning roller 14, the cleaning roller 14 rotates inside the arc groove, which can avoid secondary contamination and improve the self-cleaning ability of the cleaning roller 14.

[0025] Example 3: In this example, the residual heat of the insulation box 18 is used for cleaning, reducing energy waste. Furthermore, hot airflow cleaning improves cleaning efficiency, making it easier to remove residual impurities from the surface of the cleaning roller 14. Specifically, as follows... Figures 3-7As shown, a conveying assembly is provided under the conveying structure 1. The conveying assembly includes a fan 16 installed under the conveying structure 1. The input end of the fan 16 is connected to a second pipe 17. An insulation box 18 is fitted outside the storage box 3. The end of the second pipe 17 is connected through the inside of the insulation box 18. The output end of the fan 16 is connected to the inner cavity of the cleaning seat 15 through a third pipe 19. A through hole 20 is provided on the cleaning seat 15. A drying box 22 is connected to the third pipe 19 through a fourth pipe 21. The drying box 22 is installed under the frame 2. When the fan 16 is turned on, the fan 16 adsorbs the gas inside the insulation box 18 through the second pipe 17, and then enters the inner cavity of the cleaning seat 15 through the third pipe 19 at the output end of the fan 16, and is sprayed out through the through hole 20 on the cleaning seat 15, which facilitates the insertion of the cleaning roller 14. The cleaning process utilizes the residual heat of the insulated box 18, reducing energy waste. Hot airflow cleaning improves cleaning efficiency, making it easier to remove residual impurities from the surface of the cleaning roller 14. Furthermore, some of the preheated air in the third pipe 19 enters the drying box 22 through the fourth pipe 21. The drying box 22 evenly blows hot air onto the surface of the coating layer after it has been smoothed by the scraper 9, accelerating the evaporation of the solvent in the MOFs solution and allowing the coating layer to dry and solidify rapidly, forming a stable MOFs functional film. Rapid drying not only shortens the production cycle and improves production efficiency but also reduces shrinkage and deformation of the film layer during drying, ensuring the structural integrity and performance stability of the MOFs film. Content not described in detail in this specification is prior art known to those skilled in the art.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
