Description

Technical Field

[0001] This utility model relates to the field of coating application equipment technology, and in particular to an automated coating tool for superhydrophobic insulating coatings. Background Technology

[0002] Superhydrophobic insulating coatings are functional coatings that combine superhydrophobic properties with excellent insulation properties. By introducing hydrophobic groups and micro / nano structures, the coating surface possesses extremely low surface energy and a high water contact angle, achieving excellent hydrophobic self-cleaning capabilities and effectively resisting the adhesion of water, oil, and contaminants. Simultaneously, it contains polymeric insulating resins or ceramic fillers, possessing electrical insulation properties such as high resistance and voltage breakdown resistance. This coating is widely used in fields such as flashover protection for power equipment, moisture-proof insulation for electronic devices, and self-cleaning and protection of building exterior walls, enhancing the protective, weather-resistant, and functional properties of the substrate.

[0003] In practical applications, existing superhydrophobic insulating coatings often exhibit agglomeration and uneven dispersion before spraying or brushing due to their high viscosity and internal functional particles, such as hydrophobic nanoparticles and insulating fillers. Traditional pretreatment methods often involve manual stirring or simple settling. These methods are not only labor-intensive and inefficient, but also fail to guarantee the uniformity and stability of the coating mixture. They are highly susceptible to the influence of human operating experience and environmental conditions, potentially leading to poor consistency and low reproducibility of pretreatment results, which cannot meet the stringent quality requirements of modern automated and high-precision coating processes. Utility Model Content

[0004] This utility model discloses an automated coating tool for superhydrophobic insulating coatings, aiming to solve the technical problem that traditional pretreatment methods mostly involve manual stirring or simple standing. These traditional methods are not only labor-intensive and inefficient, but also make it difficult to ensure the uniformity and stability of coating mixing. They are easily affected by factors such as human operating experience and environmental conditions, which may lead to poor consistency and low reproducibility of pretreatment results, and fail to meet the stringent requirements of modern automated and high-precision coating processes for coating quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automated coating tool for superhydrophobic insulating coatings includes a storage cylinder. A motor is fixedly connected to the top of the storage cylinder. A feed pipe and a discharge pipe are fixedly connected to the outer wall and bottom outer wall of the storage cylinder, respectively. The storage cylinder is equipped with a stirring mechanism and a heating mechanism. The heating mechanism includes a dispersing plate. Two support frames are provided on the outer wall of the dispersing plate. The two support frames are symmetrically distributed along the center line of the motor. Several evenly distributed scrapers are hinged to one outer wall of the support frame. Three sets of equally spaced stirring components are provided on the other outer wall of the support frame.

[0006] By adopting the above technical solution, the uniformity of coating mixing can be improved, the manual burden can be reduced, and the production efficiency can be increased during coating pretreatment. Specifically, during operation, the superhydrophobic insulating coating to be treated is injected into the storage cylinder through the feed pipe. The motor drives the stirring mechanism to rotate, which drives the scraper to scrape along the cylinder wall to prevent coating adhesion and local curing. At the same time, the upward-sloping stirring rod forms an upward vortex when rotating, which promotes the uniform suspension of solid particles in the coating. The heating wire inside the stirring rod heats up synchronously during rotation, which locally heats the surrounding coating. Combined with the strong shearing action generated by the serrated outer wall of the stirring rod, the viscosity of the coating is significantly reduced. At this time, the pretreated coating can be transported to the spraying module through the feed pipe for subsequent coating work.

[0007] As a further embodiment of this utility model: the stirring assembly includes a stirring rod, the stirring rod is provided with a heating wire inside, and the outer wall edge of the stirring rod is serrated.

[0008] By adopting the above technical solution, this setting facilitates the generation of stronger shear force and disturbance effect on the coating when the stirring rod rotates. Compared with a smooth-surfaced stirring paddle, the serrated edge forms multiple irregular shear surfaces during the movement, which can effectively disperse any particle agglomerates, local high-viscosity areas, or bubble aggregation that may exist in the coating. In particular, for nano-scale hydrophobic particles or sheet-like insulating fillers, the serrated structure can significantly improve their dispersion uniformity and prevent local accumulation or settling.

[0009] As a further embodiment of this utility model: the stirring mechanism includes a connecting rod, the top end of the connecting rod is fixedly connected to the output shaft of the motor, three equally spaced fixed disks are provided on the outer wall of the connecting rod, a plurality of equally spaced stirring blades are provided on the outer wall of the fixed disks, a guide plate is provided between two adjacent fixed disks, and a material gathering plate is fixedly connected to the bottom end of the connecting rod, the guide plate having a spiral structure.

[0010] By adopting the above technical solution, when the guide plate rotates with the connecting rod, it can generate a spiral upward flow force on the coating, which facilitates the shearing and dispersing of the coating by the edge serrations of the stirring rod. The material-gathering plate can guide and gather the coating deposited at the bottom of the cylinder towards the central area during the stirring process, avoiding the coating from staying at the bottom edge for a long time. The material-gathering plate, the spiral guide plate, and the stirring blade work together to allow the coating at the bottom to participate in the stirring cycle again, improving the overall mixing uniformity. It is particularly suitable for preventing heavy particles or additives in the coating from accumulating at the bottom.

[0011] In summary, this application includes at least one of the following beneficial technical effects: 1. Effectively reduces paint viscosity and improves coating applicability: Through the mechanical shearing of the stirring rod, internal heating, and the anti-settling effect of the scraper, high-viscosity paints achieve good flowability, avoiding problems such as gun clogging and uneven coating.

[0012] 2. The serrated stirring rod and its upward tilting arrangement create an effective vortex and upward thrust, preventing hydrophobic particles or insulating fillers from settling or clumping, and ensuring uniform distribution of coating components.

[0013] Other features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0019] 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.

[0020] Reference Figure 1 , Figure 2 and Figure 3An automated coating tool for superhydrophobic insulating coating includes a storage cylinder 1. A motor 3 is fixedly connected to the top of the storage cylinder 1. A feed pipe 2 and a discharge pipe 4 are fixedly connected to the outer wall and bottom outer wall of the storage cylinder 1, respectively. The storage cylinder 1 is equipped with a stirring mechanism and a heating mechanism. The heating mechanism includes a dispersing plate 5. Two support frames 8 are provided on the outer wall of the dispersing plate 5. The two support frames 8 are symmetrically distributed along the center line of the motor 3. Several evenly distributed scrapers 6 are hinged on one side of the outer wall of the support frame 8. Three sets of equidistant stirring components are provided on the other side of the outer wall of the support frame 8.

[0021] It should be noted that the heating wire 11 can be a nickel-chromium alloy heating wire 11.

[0022] The stirring assembly includes a stirring rod 7, which has a heating wire 11 inside. The outer edge of the stirring rod 7 is serrated. This design allows the stirring rod 7 to generate stronger shear force and disturbance effect on the coating when it rotates. Compared with a smooth-surfaced stirring paddle, the serrated edge forms multiple irregular shear surfaces during the movement, which can effectively disperse any particle agglomerates, local high-viscosity areas, or bubble accumulation that may exist in the coating. In particular, for nano-scale hydrophobic particles or sheet-like insulating fillers, the serrated structure can significantly improve their dispersion uniformity and prevent local accumulation or settling.

[0023] In practical use, the stirring rod 7 is always tilted upwards to push the solid particles deposited at the bottom of the storage cylinder 1 upwards, preventing them from settling or stratifying. This helps the high-density or large-particle components in the coating to remain in a uniform suspension state during stirring, avoiding local accumulation or agglomeration and improving the overall uniformity of the coating. Compared with the traditional horizontal or vertical downward stirring method, the upward tilting stirring is more conducive to overcoming the natural settling tendency of the coating under high viscosity.

[0024] Among them, the scraper 6 has a fan-shaped structure and the dispersing plate 5 has a conical structure. The fan-shaped scraper 6 can effectively scrape off the coating deposited or adhered to the cylinder wall, avoiding the formation of a solidified layer, skin or local accumulation of coating on the cylinder wall. The conical structure of the dispersing plate 5, with its narrow top and wide bottom, helps guide the coating to flow towards the edge during rotation or flow, avoiding the coating from stagnating in the middle or forming a flow dead zone.

[0025] Specifically, during operation, the superhydrophobic insulating coating to be treated is injected into the storage cylinder 1 through the feed pipe 2. The motor 3 drives the stirring mechanism to rotate, causing the scraper 6 to scrape along the cylinder wall to prevent coating adhesion and local curing. At the same time, the upward-sloping stirring rod 7 forms an upward vortex during rotation, which promotes the uniform suspension of solid particles in the coating. The heating wire 11 inside the stirring rod 7 heats up synchronously during rotation, providing local heating to the surrounding coating. Combined with the strong shearing effect generated by the serrated outer wall of the stirring rod 7, the viscosity of the coating decreases significantly. At this time, the pretreated coating can be transported to the spraying module through the discharge pipe 4 for subsequent coating work. This device can improve the uniformity of coating mixing, reduce manual labor, and improve production efficiency during coating pretreatment.

[0026] Reference Figure 2 and Figure 4 In a preferred embodiment, the stirring mechanism includes a connecting rod 14, the top end of which is fixedly connected to the output shaft of the motor 3. Three equally spaced fixed discs are provided on the outer wall of the connecting rod 14, and several equally spaced stirring blades 12 are provided on the outer wall of the fixed discs. A guide plate 13 is provided between two adjacent fixed discs. A material gathering plate 9 is fixedly connected to the bottom end of the connecting rod 14. The guide plate 13 has a spiral structure.

[0027] It should be noted that the stirring rod 7 and the fixed plate are staggered, and the dispersing plate 5 is fixedly installed on the outer wall of the connecting rod 14.

[0028] The stirring rod 7 and the connecting rod 14 are equipped with several temperature sensors 10. The temperature sensor 10 inside the connecting rod 14 can sense the actual temperature of the coating around the stirring rod 7 in real time. Especially when the stirring rod 7 has a built-in heating wire 11, it can accurately obtain the local temperature rise of the coating caused by heating and mechanical action, which can help determine whether the coating has reached the ideal pretreatment temperature or whether local overheating has occurred.

[0029] Specifically, when the guide plate 13 rotates with the connecting rod 14, it can generate a spiral upward flow force on the coating, which facilitates the shearing and dispersing of the coating by the edge serrations of the stirring rod 7. The material gathering plate 9 can guide and gather the coating deposited at the bottom of the cylinder towards the central area during the stirring process, avoiding the coating from staying at the bottom edge for a long time. The material gathering plate 9, together with the spiral guide plate 13 and the stirring blade 12, allows the coating at the bottom to participate in the stirring cycle again, improving the overall mixing uniformity. It is particularly suitable for preventing heavy particles or additives in the coating from accumulating at the bottom.

[0030] Working principle: During operation, the superhydrophobic insulating coating to be treated is injected into the storage cylinder 1 through the feed pipe 2. The motor 3 drives the stirring mechanism to rotate, which drives the scraper 6 to scrape along the cylinder wall to prevent the coating from adhering and locally curing. At the same time, the upward-sloping stirring rod 7 forms an upward vortex when rotating, which promotes the uniform suspension of solid particles in the coating. The heating wire 11 inside the stirring rod 7 heats up synchronously during the rotation, which locally heats the surrounding coating. Combined with the strong shearing action generated by the serrated outer wall of the stirring rod 7, the viscosity of the coating decreases significantly. At this time, the pretreated coating can be transported to the spraying module through the feed pipe 4 for subsequent coating work.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
