Description
Technical Field
[0001] This utility model relates to the field of coating device technology, and in particular to a coating device for antifouling coating on aquaculture netting. Background Technology
[0002] Currently, the application of antifouling coatings to marine ranching nets is crucial, as its quality directly affects the antifouling effect and service life of the nets. At present, antifouling coatings for aquaculture nets are mainly applied using brushing, roller coating, spraying, or dip coating methods. However, these traditional methods all have many shortcomings and are difficult to meet actual production needs.
[0003] During the application of brush and roller coating, it is easy to miss areas when applying mesh with knots, resulting in insufficient coverage of the mesh knots and an inability to form a complete antifouling coating. Furthermore, it is difficult to ensure uniform coating thickness using these two methods, affecting the antifouling effect. In addition, brushing and roller coating typically require single-sided operation, leading to low work efficiency and increased labor and time costs.
[0004] While spraying can increase coating speed to some extent, it suffers from dry spraying at the mesh areas, resulting in significant paint waste and increased production costs. Dip coating also presents significant problems. Because no external force is applied during dip coating, paint adhesion is poor, making it difficult to firmly adhere to the mesh surface. Furthermore, dip coating is prone to sagging, affecting the appearance and quality of the coating. Additionally, dip coating requires large-capacity paint tanks, leading to low paint utilization and difficulties in paint recycling, further increasing costs and environmental pollution risks. Utility Model Content
[0005] The purpose of this invention is to disclose a device for applying antifouling coating to aquaculture nets, which effectively solves problems such as insufficient coverage of net knots, waste of coating, and poor mechanical adaptability.
[0006] To achieve the above objectives, this utility model discloses a coating device for antifouling paint on aquaculture netting, comprising: a transmission and pressing assembly for tensioning the netting and controlling its vertical displacement and reciprocating transmission; a paint brush roller assembly, comprising two parallel first paint brush rollers, a second paint brush roller, and a brush roller control assembly for adjusting the distance between the first and second paint brush rollers; the first paint brush rollers having first bristles arranged radially on their surfaces, and the second paint brush rollers having second bristles arranged radially on their surfaces; the first and second bristles for applying paint to the netting between the first and second paint brush rollers; a paint supply assembly for spraying paint onto the first and second bristles; and a receiving tray assembly, which is wrapped around the paint brush roller assembly and used to receive the paint.
[0007] By adopting the above scheme, the mesh can maintain a stable tension during the coating process, ensuring that all parts of the mesh, including the knots, are in full contact with the paint brush rollers. During the mesh transport, the two paint brush rollers rotate relative to each other, allowing the bristles to coat the mesh from all directions and angles, effectively covering the mesh knots and avoiding the missed coating problems that are common in traditional brush and roller coating, thus ensuring the integrity and uniformity of the coating. The paint supply component can accurately spray paint onto the bristles of the two paint brush rollers, avoiding paint waste caused by dry spraying of the mesh as in spraying methods. This concentrates the paint mainly on the bristles, resulting in a uniform coating on the mesh surface and improving paint utilization. Excess paint or dripping paint is promptly collected by the receiving tray, preventing paint from splashing and wasting, while also facilitating paint recycling and reuse, further reducing production costs. The brush roller control assembly can adjust the distance between the first and second paint brush rollers, which can be flexibly adjusted according to the thickness and material of the mesh, ensuring that the paint brush rollers and the mesh maintain a suitable contact pressure. This ensures uniform coating of the paint and avoids damage to the mesh due to excessive pressure, thus enhancing the mechanical adaptability of the device to different types of mesh.
[0008] Further, the receiving tray assembly includes: a first receiving unit, the first receiving unit including a first protective cylinder, a first cover covering the first protective cylinder, and a first receiving tray located at the bottom of the first protective cylinder, wherein the first paint brush roller and the first brush bristles are rotatably assembled inside the first protective cylinder; a second receiving unit, the second receiving unit including a second protective cylinder, a second cover covering the second protective cylinder, and a second receiving tray located at the bottom of the second protective cylinder, wherein the second paint brush roller and the second brush bristles are rotatably assembled inside the second protective cylinder, wherein a coating opening is provided on the side of the first protective cylinder opposite to the second protective cylinder for extending the first brush bristles and the second brush bristles out of the coating opening to apply paint to the mesh fabric; and a mesh fabric receiving tray, the mesh fabric receiving tray being disposed between the first receiving unit and the second receiving unit, and located directly below the mesh fabric.
[0009] By adopting the above scheme, the first and second protective cylinders enclose the brush roller, preventing paint from scattering in all directions during the brush roller's rotation. The first and second receiving trays are located at the bottom of the protective cylinders, capable of collecting paint dripping from the brush and splashing into the protective cylinders during coating due to centrifugal force, ensuring that most of the paint is effectively collected. The mesh receiving tray can collect paint dripping from the mesh during coating, further expanding the paint recovery range and preventing paint from dripping directly onto other parts of the equipment or the ground, thus improving the paint recovery rate.
[0010] Furthermore, the projected area of the mesh receiving tray on the horizontal plane is larger than the projected area of the mesh on the horizontal plane.
[0011] By adopting the above solution, the larger projected area of the mesh receiving tray can act like a large net, covering the area under the mesh in all directions. This ensures that no matter where the paint falls from the mesh or in what way, it can be caught steadily, greatly improving the paint recycling rate, reducing waste, and lowering production costs.
[0012] Furthermore, the brush roller control assembly includes a first drive member and a second drive member. The first drive member is mounted on the first cover and is used to adjust the position of the first paint brush roller inside the first protective cylinder. The second drive member is mounted on the second cover and is used to adjust the position of the second paint brush roller inside the second protective cylinder.
[0013] By adopting the above solution, the positions of the first and second paint brush rollers within the protective cylinder are adjusted using the first and second driving components, enabling precise control of the contact pressure between the brush rollers and the mesh. Different contact pressures result in varying amounts of paint transferred from the brush rollers to the mesh, thus allowing for precise adjustment of the paint coating thickness on the mesh surface. This ensures that every section of the mesh receives a uniform and compliant coating, improving its anti-fouling effect.
[0014] Further, the paint supply assembly includes: a paint tank; a nozzle assembly, the nozzle assembly including a first nozzle group disposed toward the first paint brush roller and a second nozzle group disposed toward the second paint brush roller; a guide tube bundle, one end of the guide tube bundle being connected to the paint tank and the other end being connected to the nozzle assembly; and a spray control system, the spray control system being used to control the spraying pressure of the nozzle assembly.
[0015] By adopting the above-mentioned method, directional spraying ensures that the paint is sprayed directly and accurately onto the brush roller. This allows all parts of the brush roller to be evenly coated with paint, thus ensuring that the paint is evenly applied to the mesh surface during mesh coating. This avoids uneven coating thickness caused by uneven paint distribution and improves the quality of the mesh anti-fouling coating. As long as there is sufficient paint in the paint tank, the spraying control system can continuously and stably control the spray head assembly to spray, achieving uninterrupted production and further improving production efficiency.
[0016] Furthermore, both the first and second nozzle groups include multiple linearly arranged nozzles, with the first nozzle group arranged along the axial direction of the first paint brush roller and the second nozzle group arranged along the axial direction of the second paint brush roller.
[0017] By adopting the above scheme, multiple nozzles are linearly arranged along the axial direction of the brush roller, enabling the paint to be sprayed evenly over the entire axial length of the brush roller. Each nozzle is responsible for a portion of the brush roller, and the coordinated work of multiple nozzles ensures that the brush roller is evenly coated with paint from one end to the other. In this way, when applying mesh, the brush roller can evenly apply paint to the surface of the mesh, avoiding uneven coating thickness caused by excessive or insufficient paint in certain areas of the brush roller, and improving the quality of the anti-fouling coating of the mesh.
[0018] Furthermore, the distance from the axis of the first paint brush roller to the coating opening of the first protective cylinder is greater than or equal to the radius of the first paint brush roller, and the distance from the axis of the second paint brush roller to the coating opening of the second protective cylinder is greater than or equal to the radius of the second paint brush roller.
[0019] By adopting the above solution, it can be ensured that the effective coating portion of the brush roller, i.e., the part in contact with the mesh, has sufficient space and angle to fully contact the mesh during rotation. If the distance is too small, the brush roller may not be able to fully unfold and contact the mesh, resulting in insufficient coating in some areas. Therefore, reserving enough space for the brush roller allows more coating to adhere to both the mesh and the brush roller, improving coating utilization. Appropriate clearance can also reduce vibration and noise during equipment operation.
[0020] Furthermore, it also includes a support frame, which includes a base and a bracket. The bracket is used to suspend the base above the ground. The bracket and the base enclose an assembly space, and the receiving tray assembly is assembled within the assembly space.
[0021] By adopting the above scheme, the various components of the entire coating equipment can be arranged and combined in an orderly manner, avoiding mutual interference and messy stacking between components, making full use of vertical space, accommodating more equipment and functional modules on a limited floor, and improving space utilization efficiency.
[0022] Furthermore, a support beam is provided at the top of the bracket, and the spray control system of the paint supply assembly is installed on the support beam.
[0023] By adopting the above scheme, the supporting beam, as an important structural component at the top of the support frame, possesses high strength and rigidity. Installing the spray control system on it allows the weight of the control system to be evenly distributed across the entire support structure, preventing deformation or damage to the support frame due to excessive localized stress.
[0024] Furthermore, the first paint brush roller and the second paint brush roller rotate in opposite directions.
[0025] By adopting the above method, the problems of paint accumulation or uneven application that may occur with unidirectional application are avoided, ensuring a consistent coating thickness on the mesh surface. This allows the paint to better penetrate into the fibers of the mesh, forming a tighter bond and thus enhancing the coating's adhesion. The two brush rollers rotating in opposite directions work together to repeatedly smooth and compact the coating surface. This helps eliminate defects such as bubbles and particles on the coating surface, resulting in a smoother and more even surface. A smooth coating surface not only improves the aesthetics of the mesh but also reduces water flow resistance and minimizes the impact on aquaculture organisms.
[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0027] 1. During the coating process, the force exerted by the brush bristles on the netting and the appropriate contact pressure between the brush roller and the netting allow the coating to penetrate the netting fibers more effectively, enhancing the adhesion between the coating and the netting, making the coating more durable, and extending the service life of the aquaculture netting. The relatively rotating brush roller has a repeated smoothing and compacting effect on the coating surface during coating, which helps to eliminate defects such as bubbles and particles, making the coating surface smoother and more even. This not only improves the aesthetics of the netting but also reduces water flow resistance and minimizes the impact on aquaculture organisms.
[0028] 2. Two paint brush roller sets can coat both sides of the mesh at the same time, which greatly shortens the coating time, improves work efficiency, and reduces labor and time costs. The transmission and pressing components can control the reciprocating transmission of the mesh, realize continuous and stable coating operations, reduce the time wasted due to frequent machine stops for adjustment, further improve production efficiency, and meet the needs of large-scale production.
[0029] 3. The paint supply assembly can precisely spray paint onto the bristles of the two paint brush rollers, ensuring the paint is concentrated on the bristles and then evenly coated onto the mesh surface. This avoids paint waste caused by open spraying through the mesh, as is common in spraying methods. Simultaneously, the receiving tray assembly promptly collects excess or dripping paint, facilitating recycling and reuse, thus reducing paint usage costs. The distance between the first and second paint brush rollers can be flexibly adjusted according to the thickness and material of the mesh, ensuring appropriate contact pressure between the brush rollers and the mesh. This prevents damage to the mesh and brush rollers due to excessive pressure, extending the equipment's lifespan and reducing maintenance and replacement costs.
[0030] 4. The receiving tray assembly is wrapped around the paint brush roller and bristles, which can effectively prevent paint from splashing everywhere, reduce pollution to the production environment, and provide operators with a cleaner and safer working environment. By recycling and reusing excess paint, the risk of pollution to soil, water and other environments caused by random paint discharge is reduced, which meets environmental protection requirements and is conducive to the sustainable development of enterprises.

[0040] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.
[0041] Please refer to Embodiment 1 of this utility model. Figures 1 to 2 As shown, a device for applying antifouling coating to aquaculture netting is provided, including a conveying and pressing assembly 1, a coating brush roller assembly 2, a brush roller control assembly 3, a coating supply assembly 5, and a receiving tray assembly 6. In some embodiments, to facilitate overall movement and assembly, a support frame 7 may also be included. The support frame 7 includes a base 71 and a bracket 72. The bracket 72 suspends the base 71 above the ground, and the two enclose an assembly space 73, within which the receiving tray assembly 6 is assembled. A support beam 74 is provided at the top of the bracket 72, and the spray control system 54 of the coating supply assembly 5 is installed on the support beam 74. This layout makes full use of vertical space, improves space utilization efficiency, and ensures the installation stability of the spray control system 54. Specifically, the support frame 7 consists of a metal base 71 and four vertical brackets 72. A horizontal support beam 74 is welded to the top of the brackets 72, and the base 71 is ≥50cm above the ground, forming the bottom assembly space 73.
[0042] In this embodiment 1, the transmission and pressing component 1 is used to tension the mesh 4 and control its vertical displacement and reciprocating transmission. During the coating process, this component ensures that the mesh 4 is always in a stable tension state, providing a basic condition for subsequent uniform coating. By controlling the vertical displacement of the mesh 4, it can be ensured that the edges of the mesh 4 are fully coated; while the reciprocating transmission function realizes continuous and stable coating operations, reducing the time wasted due to frequent downtime adjustments, and meeting the needs of large-scale production. Optionally, the transmission and pressing component 1 is existing technology, and this solution does not have any specific improvements, so it will not be described in detail. It is sufficient to realize the function of controlling the vertical displacement and pressing of the mesh 4.
[0043] The paint brush roller assembly 2 includes two parallel first paint brush rollers 21 and second paint brush rollers 22. The surface of the first paint brush roller 21 is provided with first bristles 211 arranged radially therefrom, and the surface of the second paint brush roller 22 is provided with second bristles 221 arranged radially therefrom. The two paint brush rollers rotate in opposite directions. During the coating process, the relatively rotating brushes can coat the mesh 4 from all directions and multiple angles, effectively covering nodules on the mesh 4 and avoiding the missed coating problems that easily occur in traditional brush and roller coating, ensuring the integrity and uniformity of the coating. Simultaneously, the two brush rollers rotating in opposite directions cooperate to repeatedly smooth and compact the coating surface, helping to eliminate defects such as bubbles and particles on the coating surface, making the coating surface smoother and more even. This not only improves the aesthetics of the mesh 4 but also reduces water flow resistance and minimizes the impact on aquaculture organisms.
[0044] The receiving tray assembly 6 encloses the paint brush roller and bristles, serving to collect paint and prevent it from splashing and being wasted. It also facilitates paint recycling and reuse, further reducing production costs. In this embodiment 1, the receiving tray assembly 6 includes a first receiving unit 61, a second receiving unit 62, and a mesh receiving tray 64. The first receiving unit 61 includes a first protective cylinder 611, a first cover 612 covering the first protective cylinder 611, and a first receiving tray 613 located at the bottom of the first protective cylinder 611. The first paint brush roller 21 and the first brush bristles 211 are rotatably assembled inside the first protective cylinder 611. The second receiving unit 62 includes a second protective cylinder 621, a second cover 622 covering the second protective cylinder 621, and a second receiving tray 623 located at the bottom of the second protective cylinder 621. The second paint brush roller 22 and the second brush bristles 221 are rotatably assembled inside the second protective cylinder 621. A coating opening 63 is provided on the side of the first protective cylinder 611 opposite to the second protective cylinder 621 to allow the first brush bristles 211 and the second brush bristles 221 to extend out of the coating opening 63 to apply paint to the mesh 4. Specifically, the first protective cylinder 611 is a semi-cylindrical stainless steel shell, with a conical first receiving tray 613 connected to the bottom. The first paint brush roller 21 passes through the first protective cylinder 611 via a bearing, and the distance between its axis and the coating opening 63 on the side wall of the first protective cylinder 611 is greater than or equal to the radius of the first paint brush roller 21. The structure of the second receiving unit 62 is symmetrical to that of the first receiving unit (61). The coating opening 63 of the second protective cylinder 621 is opposite to the coating opening 63 of the first protective cylinder 611, and the spacing is adjustable. The first protective cylinder 611 and the second protective cylinder 621 enclose the brush roller to prevent the paint from scattering in all directions during the rotation of the brush roller. The first receiving tray 613 and the second receiving tray 623 are located at the bottom of the protective cylinder and can receive the paint dripping from the brush and splashing into the protective cylinder due to centrifugal force during the coating process, ensuring that most of the paint can be effectively collected. The mesh receiving tray 64 is positioned between the first receiving unit 61 and the second receiving unit 62, directly below the mesh 4. Its function is to collect the paint dripping from the mesh 4 during the coating process. The orthographic projection area of the mesh receiving tray 64 on the horizontal plane is larger than that of the mesh 4 on the horizontal plane. This larger orthographic projection area can fully cover the area below the mesh 4, ensuring that the paint can be reliably caught regardless of where or how it falls from the mesh 4. This greatly improves the paint recovery rate, reduces waste, and lowers production costs.
[0045] The brush roller control assembly 3 includes a first drive component 31 and a second drive component 32. The first drive component 31 is mounted on the first cover 612 and is used to adjust the position of the first paint brush roller 21 within the first protective cylinder 611. The second drive component 32 is mounted on the second cover 622 and is used to adjust the position of the second paint brush roller 22 within the second protective cylinder 621. Through the first drive component 31 and the second drive component 32, the contact pressure between the brush roller and the mesh 4 can be precisely controlled. Different contact pressures result in different amounts of paint transferred from the brush roller to the mesh 4, thereby precisely adjusting the coating thickness on the surface of the mesh 4, ensuring that each area of the mesh 4 receives a uniform and satisfactory coating, and improving the anti-fouling effect. Simultaneously, this assembly can be flexibly adjusted according to the thickness and material of the mesh 4, ensuring that the paint brush roller and the mesh 4 maintain a suitable contact pressure, guaranteeing uniform coating while preventing damage to the mesh 4 due to excessive pressure, thus enhancing the device's mechanical adaptability to different types of mesh 4. In this embodiment 1, the first driving component 31 and the second driving component 32 are hydraulic cylinders. The hydraulic cylinders are respectively fixed on the first cover 612 and the second cover 622. Their respective piston rods are connected to the bearing seats of the first paint brush roller 21 and the second paint brush roller 22. The pressure range of the hydraulic system is 0.2~0.8MPa.
[0046] The paint supply assembly 5 includes a paint tank 51, a nozzle assembly 52, a guide tube bundle 53, and a spray control system 54. The nozzle assembly 52 includes a first nozzle group 521 facing the first paint brush roller 21 and a second nozzle group 522 facing the second paint brush roller 22. Both the first nozzle group 521 and the second nozzle group 522 include multiple linearly arranged nozzles. The nozzles can be fan-shaped nozzles, and the number of nozzles in the first nozzle group 521 and the second nozzle group 522 is 3-10. The number of the first nozzle group 521 and the second nozzle group 522 is at least one set. In this embodiment, the number of the first nozzle group 521 and the second nozzle group 522 are both two sets, installed on both sides of the coating opening 63.
[0047] The first nozzle assembly 521 is arranged along the axial direction of the first paint brush roller 21, and the second nozzle assembly 522 is arranged along the axial direction of the second paint brush roller 22. One end of the guide tube bundle 53 is connected to the paint tank 51, and the other end is connected to the nozzle assembly 52. The spray control system 54 is used to control the spraying pressure of the nozzle assembly 52. This directional spraying method ensures that the paint is sprayed directly and accurately onto the brush roller, so that all parts of the brush roller are evenly coated with paint. Therefore, when coating the mesh 4, the paint can be evenly applied to the surface of the mesh 4, avoiding the difference in coating thickness caused by uneven paint distribution, and improving the quality of the anti-fouling coating of the mesh 4. Moreover, as long as there is enough paint in the paint tank 51, the spray control system 54 can continuously and stably control the nozzle assembly 52 to spray, realizing uninterrupted production and further improving production efficiency.
[0048] During operation, the surface of the aquaculture netting 4 is cleaned to remove dust and adhering substances to ensure coating adhesion. The aquaculture netting 4 includes both knotted and knotless netting, made of synthetic fibers such as polyethylene (PE), nylon (PA), polypropylene (PP), and polyester fiber (PET). The cleaned netting 4 is folded using the transmission and clamping assembly 1 and fixed on both sides along its length, ensuring it is under tension to provide stable conditions for subsequent coating operations. The device is then activated, and the coating supply assembly 5 begins operation. The spray control system 54 controls the nozzle assembly 52 to spray coating onto the bristles of the two coating brush rollers at a set pressure. Under the adjustment of the brush roller control assembly 3, the first and second coating brush rollers 21 and 22 maintain appropriate contact pressure with the netting 4 and rotate in opposite directions. The bristles coat the netting 4 from all angles, ensuring the coating evenly covers the surface, including knots and gaps, enhancing the adhesion between the coating and the netting 4 and ensuring the durability and reliability of the netting 4's anti-fouling effect. During the coating process, the conveying and pressing assembly 1 controls the reciprocating conveyance of the netting 4 to achieve continuous and stable coating operations. If multiple coatings are required, the conveying and pressing assembly 1 is used to repeatedly convey and coat the netting 4, depending on the application scenario and the type of coating. During the coating process, excess or dripping coating is promptly collected by the receiving tray assembly 6. The first receiving tray 613 and the second receiving tray 623 collect coatings dripping from the brush and splashing into the protective cylinder due to centrifugal force during the coating process; the netting receiving tray 64 collects coatings dripping from the netting 4. These collected coatings can be recycled and reused, reducing the cost of coating use and also reducing environmental pollution. After coating, the netting 4 is untied and hung to air dry, blow dry, or bake dry, allowing the antifouling coating to form a stable antifouling coating on the surface of the netting 4, thus completing the antifouling coating work on the aquaculture netting 4.
[0049] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0050] 1. During the coating process, the force exerted by the brush bristles on the net 4 and the appropriate contact pressure between the brush roller and the net 4 allow the coating to penetrate better into the fibers of the net 4, enhancing the adhesion between the coating and the net 4, making the coating more durable, and extending the service life of the aquaculture net 4. The relatively rotating brush roller has a repeated smoothing and compacting effect on the coating surface during coating, which helps to eliminate defects such as bubbles and particles, making the coating surface smoother and more even. This not only improves the aesthetics of the net 4, but also reduces water flow resistance and reduces the impact on aquaculture organisms.
[0051] 2. The two paint brush roller groups 2 can coat both sides of the mesh 4 simultaneously, which greatly shortens the coating time, improves work efficiency, and reduces labor and time costs. The transmission and pressing component 1 can control the reciprocating transmission of the mesh 4 to achieve continuous and stable coating operations, reduce the time wasted due to frequent machine stops for adjustment, further improve production efficiency, and meet the needs of large-scale production.
[0052] 3. The paint supply assembly 5 can precisely spray paint onto the bristles of the two paint brush rollers, ensuring that the paint is mainly concentrated on the bristles and then evenly coated onto the surface of the mesh 4. This avoids paint waste caused by open spraying through the mesh, as is common in spraying methods. Simultaneously, the receiving tray assembly 6 promptly collects excess or dripping paint, facilitating recycling and reuse, thus reducing paint usage costs. The distance between the first paint brush roller 21 and the second paint brush roller 22 can be flexibly adjusted according to the thickness and material of the mesh 4, ensuring appropriate contact pressure between the paint brush rollers and the mesh 4. This prevents damage to the mesh 4 and brush rollers due to excessive pressure, extending the equipment's service life and reducing maintenance and replacement costs.
[0053] 4. The receiving tray assembly 6 is wrapped around the paint brush roller and bristles, which can effectively prevent paint from splashing everywhere, reduce pollution to the production environment, and provide operators with a cleaner and safer working environment. By recycling and reusing excess paint, the risk of pollution to soil, water and other environments caused by random paint discharge is reduced, which meets environmental protection requirements and is conducive to the sustainable development of enterprises.
[0054] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
