Description

Technical Field

[0001] This utility model belongs to the field of coating equipment technology, specifically relating to a breathable, fireproof, and water-repellent cloth coating mechanism. Background Technology

[0002] Breathable, fireproof, and water-repellent fabric is a high-performance composite material that integrates three core functions: fireproof, waterproof, and breathable. It is mainly used in scenarios where flame retardancy, moisture resistance, and air circulation are required simultaneously.

[0003] Breathable, fireproof, and water-repellent fabric uses alkali-free fiberglass cloth as the base material. Nanoscale polymer materials (such as flame-retardant silicone oil or fluoride coating) are coated on the surface of the fiberglass cloth. Through a special process, a microstructure similar to the surface of a lotus leaf is formed to achieve a water-repellent effect. Some products adopt a double-layer coating design, with silicone oil layers coated on both sides of the substrate to further enhance waterproof and fireproof performance. At the same time, the microporous structure allows for the exchange of air and water vapor.

[0004] Coating equipment is an important piece of machinery for processing breathable, fireproof, and water-repellent fabrics, used to coat the surface of the base fabric with nanoscale polymer materials.

[0005] Currently, commonly used coating equipment, such as the Chinese utility model patent with authorization announcement number CN222970161U, discloses "a coating device with adjustable coating spacing", which includes a worktable. The top surface of the worktable is fixedly connected to two symmetrically distributed U-shaped frames. The inner walls of the two U-shaped frames are slidably connected to slide plates. A coating structure is installed between the end walls of the two slide plates that are close to each other. A forward and reverse motor drives the active bevel gear to rotate, which in turn drives the driven bevel gear to rotate the lifting screw, thereby causing the moving plate to lift or lower the coating structure, thus realizing the adjustment of the coating spacing.

[0006] While existing coating devices, including those described above, can meet general usage requirements, the tension of the base fabric is not adjustable, which can easily lead to uneven coating due to localized tension imbalances during the coating process.

[0007] To solve the above problems, this utility model proposes a breathable, fireproof, and water-repellent fabric coating mechanism. Utility Model Content

[0060] 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.

[0061] Please see Figures 1-5 The present invention provides the following technical solution: a breathable, fireproof and water-repellent cloth coating mechanism, including a coating platform 1, and further including: a feeding component 2, a transition mechanism 3, an adjustment mechanism 4, a support component 5, a coating mechanism 7 and a receiving component 8.

[0062] Furthermore, by Figure 1 and Figure 2 As shown, in this embodiment, the feeding assembly 2 is used to provide the base fabric material to be coated. The transition mechanism 3 is located on one side of the feeding assembly 2. It includes a movable frame 31 with an installation port 311 and movably installed on the coating platform 1, an installation block 32 located in the installation port 311, a transition roller 33 rotatably installed between the two installation blocks 32, and a pressure sensor 34 fixed to the top surface inside the installation port 311. The top surface of the installation block 32 is in contact with the detection surface of the pressure sensor 34. The adjustment mechanism 4 is used to adjust the initial height of the transition roller 33. Two sets of support assemblies 5 are spaced apart on the top of the coating platform 1. The coating mechanism 7 is located between the two sets of support assemblies 5. The take-up assembly 8 is used to take up the coated base fabric material. With the above scheme, when in use, the feeding assembly 2 first places the base fabric material to be coated, and the base fabric is released from the assembly.

[0063] The transition mechanism 3 is located on one side of the feeding assembly 2. The adjustment mechanism 4 can adjust the initial height of the transition roller 33 to adapt to different coating requirements and ensure that the base fabric is under appropriate tension during the conveying process.

[0064] The movable frame 31 is movably mounted on the coating platform 1. When the adjusting mechanism 4 adjusts the height of the transition roller 33, the movable frame 31 will move accordingly on the coating platform 1. The mounting block 32 moves with the movable frame 31, thereby driving the transition roller 33 to move up and down until the appropriate initial height is reached.

[0065] The base fabric passes under the transition roller 33. Due to the tension of the base fabric during the conveying process, pressure is generated on the transition roller 33. This pressure is transmitted to the pressure sensor 34 through the mounting block 32. The pressure sensor 34 detects the pressure value in real time and feeds the pressure signal back to the control system. The control system controls the adjustment mechanism 4 to fine-tune the height of the transition roller 33 according to the preset pressure range and the feedback pressure signal, so as to maintain the stability of the tension of the base fabric during the conveying process and avoid problems such as wrinkles and stretching deformation of the base fabric due to excessive or insufficient tension.

[0066] After being stably conveyed by the transition mechanism 3, the base fabric enters the two sets of support components 5 spaced apart on the top of the coating platform 1 and passes over the two sets of support components 5. The support components 5 support and guide the base fabric, keeping it flat and conveying it forward stably.

[0067] The coating mechanism 7, located between the two sets of support components 5, begins to work, and its internal coating device evenly coats the prepared breathable, fireproof, and water-repellent coating liquid onto the surface of the base fabric.

[0068] After coating, the base fabric continues to be conveyed forward and eventually reaches the receiving component 8. The receiving component 8 winds up the coated base fabric to complete the entire coating process.

[0069] Throughout the entire process, the components work together, and through the feedback control of the adjustment mechanism 4 and the pressure sensor 34, the stability of the base fabric conveying and the uniformity of the coating are ensured, thereby achieving efficient and high-quality coating production of breathable, fireproof and water-repellent fabric.

[0070] Optionally, by Figures 1-3As shown, in this embodiment, the adjustment mechanism 4 includes: a connecting plate 41, a first cylinder 42, and a first guide post 43. The movable frame 31 penetrates the coating platform 1 to form a sliding structure. The connecting plate 41 is fixed to the bottom of the movable frame 31. The first cylinder 42 is fixed to the bottom surface of the coating platform 1, and the piston rod of the first cylinder 42 is fixedly connected to the connecting plate 41. The two first guide posts 43 are symmetrically fixed to the bottom surface of the coating platform 1 and penetrate the connecting plate 41. With the above scheme, when it is necessary to adjust the initial height of the transition roller 33, the first cylinder 42 is activated. The first cylinder 42 is fixed to the bottom surface of the coating platform 1, and its piston rod is fixedly connected to the connecting plate 41. The connecting plate 41 is rigidly connected to the bottom of the movable frame 31. Since the movable frame 31 penetrates the coating platform 1 and forms a sliding structure, when the piston rod of the first cylinder 42 moves in extension and retraction, it will drive the movable frame 31 to slide vertically along the through hole of the coating platform 1 through the connecting plate 41.

[0071] At this time, the two symmetrically arranged first guide columns 43 penetrate the guide holes on the connecting plate 41, providing precise guidance for the lifting and lowering of the movable frame 31, preventing it from shifting laterally or tilting during movement, and ensuring that the height adjustment process of the transition roller 33 is smooth and vertical.

[0072] During the initial height setting stage, the operator can preset the target height of the transition roller 33 through the control system. The first cylinder 42 drives the piston rod to extend or retract according to the control signal until the pressure sensor 34 detects that the initial pressure value transmitted by the mounting block 32 meets the tension requirements of the base fabric conveying.

[0073] Once the base fabric begins to be conveyed, the pressure sensor 34 monitors the changes in base fabric tension in real time and feeds them back to the control system. If the tension is abnormal due to changes in the base fabric roll diameter or coating resistance, the control system will automatically send a fine-tuning signal to the first cylinder 42: when the tension is too high, the piston rod of the first cylinder 42 is shortened, causing the movable frame 31 to drive the transition roller 33 to rise, reducing the tension of the base fabric; when the tension is too low, the piston rod is extended, lowering the height of the transition roller 33 to tighten the base fabric.

[0074] The first guide post 43 not only improves the stability of the movement of the movable frame 31, but also effectively disperses the lateral load borne by the piston rod of the first cylinder 42, extending the service life of the cylinder.

[0075] Throughout the adjustment process, the rigid connection of the mechanical structure and the precise coordination of the guiding system ensure that the height adjustment of the transition roller 33 is responsive and accurately positioned. It forms a closed-loop control with the pressure sensor 34, dynamically balancing the tension of the base fabric in real time, and providing stable substrate conveying conditions for subsequent coating processes.

[0076] Optionally, by Figure 1 and Figure 4As shown, in this embodiment, four support columns 6 are fixed diagonally to the top surface of the coating platform 1. The coating mechanism 7 includes: a top plate 71 fixed to the top of the support columns 6, a first n-shaped frame 72 located below the top plate 71, a coating roller 73 rotatably installed inside the first n-shaped frame 72, a drive motor 74 for driving the coating roller 73 to rotate, a second cylinder 75 fixed to the top surface of the top plate 71, and two second guide columns 76 symmetrically fixed to the top surface of the first n-shaped frame 72. The drive motor 74 is fixed to one end of the first n-shaped frame 72. The piston rod of the second cylinder 75 passes through the top plate 71 and is connected to the first n-shaped frame 72. The second guide columns 76 pass through the top plate 71. With the above scheme, when the base fabric is stably transported to the coating area through the transition mechanism 3 and the support assembly 5, the coating mechanism 7 starts to perform the coating operation.

[0077] Four diagonally distributed support columns 6 provide a stable support foundation for the top plate 71, ensuring the rigid structure of the entire coating mechanism 7. The coating roller 73 is rotatably mounted inside the first n-shaped frame 72 through bearings, and its surface forms a contact area with the base fabric conveying path. The drive motor 74 is connected to the coating roller 73 through a coupling, providing a constant speed for the coating roller 73, so that the coating liquid can be evenly transferred to the surface of the base fabric.

[0078] Before coating, the operator can set the coating thickness process parameters through the control system. The second cylinder 75 drives the piston rod to extend and retract according to the preset parameters, which drives the first n-shaped frame 72 to move vertically. Since the second guide column 76 symmetrically passes through the guide hole on the top plate 71, its linear guiding effect ensures that the first n-shaped frame 72 does not deflect during the lifting process, thereby accurately controlling the contact pressure between the coating roller 73 and the base fabric. The greater the pressure, the more the coating liquid penetrates and adheres to the base fabric, and vice versa.

[0079] During the coating process, the second cylinder 75 and the pressure sensor 34 form a linkage control: if the tension of the base fabric fluctuates due to the coating resistance, the control system adjusts the height of the transition roller 33 while simultaneously fine-tuning the output pressure of the second cylinder 75 to ensure that the contact force between the coating roller 73 and the base fabric remains stable, thus avoiding uneven coating thickness due to tension changes.

[0080] Preferably, by Figure 1 and Figure 4 As shown, in this embodiment, the coating mechanism 7 further includes: a second n-type frame 77 located on one side of the first n-type frame 72, a rubber strip 78 disposed in the second n-type frame 77, and an adjustment component 79 for adjusting the initial height of the second n-type frame 77. With the above scheme, when the base fabric is initially coated by the coating roller 73, the second n-type frame 77 located on one side of the first n-type frame 72 begins to function.

[0081] The rubber strip 78 inside the second n-type frame 77 is made of a highly elastic solvent-resistant material. Its bottom surface forms a flexible contact with the base fabric surface and is mainly used to scrape off excess coating liquid from the base fabric surface and smooth the coating.

[0082] The adjustment component 79 can precisely control the initial height of the second n-type frame 77, thereby adjusting the contact pressure between the rubber strip 78 and the base fabric to meet the requirements of different coating processes for coating thickness and surface flatness.

[0083] Before the coating operation, the operator sets the initial height of the second n-shaped frame 77 by adjusting component 79: when a thick coating is required, adjusting component 79 drives the second n-shaped frame 77 to descend, so that the rubber strip 78 is slightly pressed into the surface of the base fabric, and the excess coating liquid is scraped off by elastic deformation; when a thin coating or glossy effect is required, the height of the second n-shaped frame 77 is raised, so that the rubber strip 78 adheres to the base fabric with less pressure, only playing a role in surface flattening. The flexible contact characteristics of the rubber strip 78 can adapt to the slight undulations of the base fabric, avoiding damage to the base fabric or scratches on the coating due to rigid scraping.

[0084] It is worth noting that, similar to the height adjustment of the coating roller 73 mentioned above, the greater the pressure, the larger the contact area between the coating roller and the substrate, and the better the coating is squeezed onto the substrate, resulting in a thicker coating; conversely, the smaller the pressure, the smaller the contact area between the coating roller and the substrate, the less uniform the coating distribution, and the thinner the coating.

[0085] Optionally, by Figure 1 and Figure 4 As shown, in this embodiment, the adjustment component 79 includes: a fixing plate 791 fixed to the outer wall of the first n-shaped frame 72, a threaded screw 792 threadedly engaged with the fixing plate 791, a handle 793 fixed to the top of the threaded screw 792, and two third guide posts 794 symmetrically fixed to the top surface of the second n-shaped frame 77. The bottom end of the threaded screw 792 is rotatably connected to the second n-shaped frame 77, and the third guide posts 794 penetrate the fixing plate 791. With the above solution, when it is necessary to adjust the initial height of the rubber strip 78, the operator rotates the threaded screw 792 through the handle 793. Because the threaded screw 792 is threadedly engaged with the fixing plate 791, the rotational motion is converted into the vertical linear motion of the threaded screw 792 through the threaded pair, which drives the second n-shaped frame 77 to move vertically. The second n-shaped frame 77 drives the rubber strip 78 to move vertically, changing the height of the rubber strip 78, that is, the distance between the rubber strip 78 and the base fabric.

[0086] Two symmetrically arranged third guide pillars 794 pass through guide holes on the fixed plate 791. Their bottom ends are fixedly connected to the top surface of the second n-shaped frame 77, and their top ends are suspended and maintain a sliding fit with the fixed plate 791. This structure provides rigid guidance for the lifting and lowering of the second n-shaped frame 77, ensuring that it moves only in the vertical direction under the drive of the threaded screw 792, avoiding tilting or jamming caused by off-center loading.

[0087] Preferably, by Figure 1 , Figure 4 and Figure 5 As shown, this embodiment also includes: a T-shaped strip 781 fixed to the top side of the rubber strip 78, and a T-shaped groove 771 that mates with the T-shaped strip 781 is provided in the second n-shaped frame 77. With the above solution, when in use, the rubber strip 78 forms an embedded fit with the T-shaped groove 771 in the second n-shaped frame 77 through the T-shaped strip 781 on the top side. This structural design realizes the quick installation and positioning and convenient replacement of the rubber strip 78.

[0088] Optionally, by Figure 1 As shown, in this embodiment, the feeding assembly 2 includes: two first fixing frames 21 symmetrically fixed to the top surface of the coating platform 1, a feeding roller 22 rotatably installed between the two first fixing frames 21, and a first servo motor 23 for driving the feeding roller 22 to rotate. The first servo motor 23 is fixed to the first fixing frame 21. With the above scheme, in use, the feeding assembly 2 serves as the starting point for base fabric conveying. The feeding roller 22 is driven to rotate by the first servo motor 23 to achieve uniform release of the base fabric to be coated.

[0089] Optionally, by Figure 1 As shown, in this embodiment, the support component 5 includes: two second fixed frames 51 symmetrically fixed to the top surface of the coating platform 1, a support roller 52 rotatably installed between the two second fixed frames 51, and a second servo motor 53 for driving the support roller 52 to rotate. The second servo motor 53 is fixed to the second fixed frame 51. With the above scheme, in use, the support component 5 serves as a key support unit for the base fabric conveying path. The second servo motor 53 drives the support roller 52 to rotate, thereby achieving stable support and guidance of the base fabric.

[0090] Two sets of support components 5 work together to support the base fabric, ensuring that the base fabric remains horizontal in the coating section and guaranteeing the coating quality.

[0091] Optionally, by Figure 1As shown, in this embodiment, the take-up assembly 8 includes: two third fixing frames 81 symmetrically fixed to the top surface of the coating platform 1, a take-up roller 82 rotatably installed between the two third fixing frames 81, and a third servo motor 83 for driving the take-up roller 82 to rotate. The third servo motor 83 is fixed to the third fixing frame 81. With the above scheme, in use, the take-up assembly 8 serves as the terminal winding unit after the base fabric is coated. The take-up roller 82 is driven to rotate by the third servo motor 83 to achieve uniform winding of the coated base fabric.

[0092] It should be noted that the first servo motor 23, pressure sensor 34, first cylinder 42, second servo motor 53, drive motor 74, second cylinder 75 and third servo motor 83 are all commercially available conventional devices with built-in power switches. Those skilled in the art can make conventional selections according to their needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated on further in this article.

[0093] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0094] Components not described in detail in this article are existing technologies.

[0095] The working principle and usage process of this utility model: When the base fabric is stably transported to the coating area through the transition mechanism 3 and the support component 5, the coating mechanism 7 begins to perform the coating operation.

[0096] Four diagonally distributed support columns 6 provide a stable support foundation for the top plate 71, ensuring the rigid structure of the entire coating mechanism 7. The coating roller 73 is rotatably mounted on the inner side of the first n-shaped frame 72 through bearings, and its surface forms a contact area with the base fabric conveying path. The drive motor 74 is connected to the coating roller 73 through a coupling, providing a constant speed for the coating roller 73, so that the coating liquid can be evenly transferred to the surface of the base fabric.

[0097] Before coating, the operator can set the coating thickness process parameters through the control system. The second cylinder 75 drives the piston rod to extend and retract according to the preset parameters, which drives the first n-shaped frame 72 to move vertically. Since the second guide column 76 symmetrically passes through the guide hole on the top plate 71, its linear guiding effect ensures that the first n-shaped frame 72 does not deflect during the lifting process, thereby accurately controlling the contact pressure between the coating roller 73 and the base fabric. The greater the pressure, the more the coating liquid penetrates and adheres to the base fabric, and vice versa.

[0098] During the coating process, the second cylinder 75 and the pressure sensor 34 form a linkage control: if the tension of the base fabric fluctuates due to the coating resistance, the control system adjusts the height of the transition roller 33 while simultaneously fine-tuning the output pressure of the second cylinder 75 to ensure that the contact force between the coating roller 73 and the base fabric remains stable, thus avoiding uneven coating thickness due to tension changes.

[0099] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
