Technical Field
[0001] This utility model relates to the field of automatic coating technology, and in particular to an automatic coating device for water-based paints suitable for continuous production. Background Technology
[0002] In modern industrial production, water-based paints are widely used in surface treatment processes for numerous products due to their environmentally friendly properties and excellent coating effects, such as automobile manufacturing, furniture production, and the coating of various electronic product casings. With the continuous increase in market demand, continuous and automated production has become a trend, leading to the development of automated water-based paint coating devices suitable for continuous production. These devices reduce the uncertainty caused by manual intervention, lower production costs, and drive related industries towards greater efficiency and intelligence.
[0003] Traditional water-based paint processing equipment has focused primarily on basic functional implementation in its structural design. Common filtration devices mainly rely on simple filter screen structures, allowing the water-based paint to slowly flow through the screen via static filtration or low-speed water flow to remove particulate impurities. For mixing, a low-speed agitator is typically used, directly connected to a motor shaft, rotating at a fixed speed within the paint tank to mix the paint components.
[0004] As production continues, impurities accumulate at the nozzle, gradually reducing the nozzle orifice diameter and preventing the nozzle from spraying paint properly. This not only disrupts the uniformity of the coating, resulting in mottled and uneven paint layers on the product surface, but also reduces production efficiency. Frequent shutdowns for cleaning or replacing nozzles due to malfunctions consume significant manpower, resources, and production time, hindering continuous production and failing to meet the urgent need for high-efficiency manufacturing. Therefore, an automatic water-based paint coating device suitable for continuous production is proposed to solve these problems. Summary of the Invention
[0005] To overcome the above shortcomings, this utility model provides an automatic water-based paint coating device suitable for continuous production, aiming to improve the problem of filter clogging in the prior art, which leads to malfunction.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An automatic water-based paint coating device suitable for continuous production includes a machine body. Support legs are fixedly connected to the bottom of the machine body.

[0010] As a further description of the above technical solution:
[0011] An adjusting valve is fixedly connected inside the machine body, and a fixed base is fixedly connected to the top of the storage tank.
[0012] As a further description of the above technical solution:
[0013] A motor three is fixedly connected to the top of the fixed base, a gear two is fixedly connected to the output end of the motor three, and a worm gear one is fixedly connected to the bottom of the gear two.
[0014] As a further description of the above technical solution:
[0015] A worm gear is rotatably connected to the side wall of the storage tank, and the worm meshes with the worm gear.
[0016] As a further description of the above technical solution:

The outer wall of the second worm gear is rotatably connected to the inner wall of the storage tank, and a gear is rotatably connected inside the storage tank.
[0018] As a further description of the above technical solution:
[0019] The gear one is internally slidably connected to a retaining pin, and the outer wall of the retaining pin is rotatably connected to a worm gear two, which meshes with the worm wheel two.
[0020] As a further description of the above technical solution:
[0021] A stirring paddle is fixedly connected to the bottom of the locking post, and gear one meshes with gear two.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, the connecting plate is rotated by starting the second motor, which in turn drives the rotating rod to rotate, thereby causing the sliding block to slide inside the groove, and then causing the bottom of the placement plate to slide on the support plate, thus cleaning the scraper. This solves the problem that during filtration, particulate impurities in water-based paint will accumulate at the nozzle, causing the nozzle to malfunction and affecting the spraying effect and production efficiency.
[0024] In this invention, starting motor three drives worm gear one to rotate, which in turn drives rotating arm to rotate, which in turn drives worm wheel two to rotate. This causes the locking pin to slide on the inner wall of worm gear two, driving worm wheel two to rotate, so that worm gear two and worm wheel two mesh. Finally, the locking pin rises and falls, driving the stirring paddle to stir, preventing local component differences, thereby improving coating quality. Attached Figure Description

A motor 6 is fixedly connected to one side of the coating roller 4. The motor 6 is a high-efficiency, energy-saving three-phase asynchronous motor. The output end of the motor 6 is fixedly connected to... Conveyor roller 3, made of wear-resistant rubber, is used to convey the workpiece to be coated, ensuring a smooth production process. An operation panel 5 is fixedly connected to the top of the machine body 1. The operation panel 5 is equipped with a high-resolution LCD screen, and its outer shell is made of insulating and impact-resistant ABS plastic, facilitating real-time monitoring and precise control of various parameters by the operator. Motor 2 11 is fixedly connected to the top of the machine body 1. Motor 2 11 is a servo motor with high torque output characteristics, and its speed control capability provides strong support for subsequent complex actions. A connecting plate 12 is fixedly connected to the output end of motor 2 11. The connecting plate 12 has a rectangular plate structure and is made of aviation aluminum alloy, which is lightweight and high-strength. The side walls of the connecting plate 12... A rotating rod 13 is rotatably connected, and the rotating rod 13 is a solid rod made of high-strength alloy steel. A sliding block 15 is rotatably connected to one side of the rotating rod 13. A support plate 17 is fixedly connected inside the machine body 1. The support plate 17 is made of thick hot-rolled steel plate, which has been finely processed and polished, resulting in a high degree of surface flatness. The top of the support plate 17 is slidably connected to the placement plate 14 using a low-friction guide rail slider structure, ensuring that the placement plate 14 moves smoothly and stably. A groove 16 is provided inside the placement plate 14. The inner wall of the groove 16 is smooth, and the dimensional tolerance is controlled within a small range, providing guidance for the sliding block 15. The bottom of the sliding block 15 is slidably connected inside the groove 16. Its main body material is high-strength nylon, which has both good wear resistance and can effectively reduce wear. The noise during light operation is minimized. A filter screen 29 is fixedly connected to the bottom of the coating roller 4. The filter screen 29 is made of high-precision stainless steel wire with fine and uniform mesh, which can intercept various tiny particles and impurities in water-based paint, ensuring coating quality. A scraper 18 is fixedly connected to one side of the sliding block 15. The top of the scraper 18 is made of soft and wear-resistant polyurethane rubber, which can not only fit closely to the bottom of the filter screen 29 for efficient cleaning, but also avoid scratching the filter screen 29, ensuring the long-term stable operation of the entire device. The brush closely connected to it is made of nylon filaments. Through strong glue and anchoring technology, it is ensured that it does not move at all during high-speed operation and strong scraping, realizing precise filtration and high-quality coating of water-based paint in continuous production process.
[0033] Specifically, by rotating the regulating valve 10, whose internal valve core is made of high-strength corrosion-resistant alloy, the valve is smooth to the touch and precisely positioned, controlling the flow rate to extract the paint from the storage tank 7. The storage tank 7 is made of food-grade plastic, which is impact-resistant and chemically stable, ensuring the purity of the paint. The paint then travels along the conveying pipe to the coating roller 4, ready to coat the fabric. Next, the motor 6 is started. As the core power source of the entire conveying process, it can effectively prevent dust and moisture, and drives the conveying roller 3 to rotate at a constant speed. At this time, the fabric is smoothly pushed forward under the traction of the conveying roller 3, and the paint is evenly transferred from the coating roller 4 to the surface of the fabric. If the paint shows signs of blockage during the conveying process, the motor 11 is started to drive the connecting plate 12 made of stainless steel to rotate quickly, which in turn links the rotating rod 13, causing the placement plate 14 to slide on the guide rail of the support plate 17. The rubber limit block on the top of the placement plate 14 ensures that the sliding block 15 moves accurately, and finally drives the scraper 18 to efficiently clean the filter screen 29, maintaining the smooth operation of the equipment.
[0034] Reference Figure 3 and Figure 4A hinge 8 is fixedly connected to the side wall of the machine body 1. The hinge 8 is made of high-quality stainless steel and has a compact and reasonable structural design to ensure the smooth operation of the entire device. A storage tank 7 is fixedly connected to the side wall of the hinge 8. The main body of the storage tank 7 is made of high-strength and corrosion-resistant polyethylene plastic. This material is not only chemically stable and can resist the erosion of various chemical components in water-based paint, but also has good flexibility and can adapt to a certain degree of pressure change to prevent the tank from cracking or leaking, thus ensuring the safety of the stored paint. A hose 9 is fixedly connected between the machine body 1 and the storage tank 7. The hose 9 is made of high-performance rubber material that is resistant to acids and alkalis and wear. It is lined with multiple layers of high-strength fiber braiding, which can ensure good sealing under frequent bending and stretching conditions to prevent paint leakage, and can also withstand a certain internal pressure to ensure stable paint transmission.To control the flow rate and velocity of the paint liquid, a regulating valve 10 is fixedly connected inside the machine body 1. The outer shell of the regulating valve 10 is made of cast aluminum, providing good heat dissipation and mechanical strength. A mounting base 20 is fixedly connected to the top of the storage tank 7. The mounting base 20 is made of thick carbon steel through machining and welding, and its surface has been treated with anti-rust treatment, providing a stable installation foundation for the motor 3 19 above. The motor 3 19 is fixedly connected to the top of the mounting base 20. The motor 3 19 is a high-performance DC brushless motor, which has many advantages such as low noise, high torque, and precise speed control. A gear 28 is fixedly connected to the output end of the motor 3 19. The gear 28 is forged from alloy steel. The gears are precision-milled, resulting in high tooth surface hardness and excellent meshing accuracy. A worm gear 21 is fixedly connected to the bottom of gear 28. Worm gear 21 is also made of high-quality alloy steel, featuring a scientifically designed spiral profile and surface hardening treatment, providing excellent wear resistance and transmission efficiency. A worm wheel 22 is rotatably connected to the side wall of storage tank 7. Worm wheel 22 is made of bronze, which, when combined with worm gear 21, provides excellent self-lubrication and friction-reducing properties, effectively reducing energy loss and wear during transmission and ensuring stable operation over long periods. Worm gear 21 meshes with worm wheel 22, and a rotating arm 23 is rotatably connected to the side wall of worm wheel 22. Rotating arm 23 is made of lightweight aluminum. Made of alloy material and mechanically optimized, this design minimizes weight and inertial resistance while ensuring structural strength, ensuring rapid and stable motion response. A second worm gear 24, also made of bronze, is rotatably connected to the other side of the rotating arm 23. Its outer wall is smoothly connected to the inner wall of the storage tank 7 via a custom-designed wear-resistant sliding sleeve. The sleeve is made of special engineering plastic with a low coefficient of friction and excellent wear resistance, ensuring stable rotation of the second worm gear 24. The outer wall of the second worm gear 24 is rotatably connected to the inner wall of the storage tank 7. Inside the storage tank 7, a gear 26 is rotatably connected, and a locking pin 30 is slidably connected inside the gear 26. The locking pin 30 is made of high-strength stainless steel. Made of stainless steel with a smooth surface and high machining precision, it ensures smooth sliding within gear 26 and provides a stable and reliable fulcrum for worm gear 25. Worm gear 25 is rotatably connected to the outer wall of the locking post 30, and worm gear 25 meshes with worm wheel 24. A stirring paddle 27 is fixedly connected to the bottom of the locking post 30, and gear 26 meshes with gear 28. The stirring paddle 27 is made of corrosion-resistant, high-strength stainless steel, and its blade shape is optimized by fluid mechanics, with multiple angles of inclination. Driven by a motor, it can agitate the water-based paint in the storage tank 7, preventing the paint components from settling and separating, ensuring that the paint used each time is uniform and consistent, and meeting the paint quality requirements of continuous production.
[0035] Specifically, by starting the motor 319, the output gear 28 rotates accordingly. Gear 28 is forged from high-strength alloy steel with precise tooth profile and excellent meshing performance. The rotating gear 28 drives the worm gear 21 to rotate synchronously. The worm gear 21 is made of wear-resistant nitrided steel with extremely high surface hardness. It meshes with the bronze worm wheel 22, smoothly transmitting power and driving the worm wheel 22 to rotate. This, in turn, drives the rotating arm 23, made of high-strength aluminum alloy, to swing flexibly. The action of the rotating arm 23 acts on the worm wheel 24. At the same time, gear 28 meshes with gear 26, causing the worm gear 25 to rise and fall, which in turn drives gear 26 to rotate. The meshing of worm gear 25 and worm wheel 24 ultimately achieves stable lifting and lowering of the locking column 30. The stirring paddle 27 welded to its bottom efficiently stirs the paint liquid. The 27-blade agitator has a special streamlined shape that can agitate the paint in all directions, instantly activating all components of the paint and laying a solid foundation for subsequent coating operations, thereby improving the color consistency and adhesion of the finished coating.
[0036] Working principle: When the automatic coating machine needs to be filtered, the coating is drawn from the storage tank 7 by rotating the regulating valve 10, and then the coating is conveyed to the coating roller 4 to coat the fabric. At the same time, the motor 6 is started to drive the conveying roller 3 to rotate. When the substrate moves forward under the drive of the conveying roller 3, the coating is evenly transferred and coated on the surface of the fabric. During the coating process, blockage may occur. At this time, the motor 11 is started, which drives the connecting plate 12 to rotate, which in turn drives the rotating rod 13 to rotate. Then, the bottom of the placement plate 14 slides on the support plate 17, and the sliding block 15 moves inside the chute 16. The top of the placement plate 14 is equipped with a limit block, which limits the sliding block 15 when it slides. Then, the scraper 18 on the top of the sliding block 15 moves, thereby driving the scraper 18 to clean the bottom of the filter screen 29. By cleaning the filter screen 29, these impurities that block the equipment can be removed, ensuring the smooth flow of the nozzle and pipeline and reducing the probability of equipment failure.
[0037] When water-based paint becomes uneven during storage or transportation, motor 19 is activated. Worm gear 21 and worm wheel 22 mesh, driving gear 28 to rotate. This, in turn, rotates worm gear 21, which in turn rotates worm wheel 22. The meshing of worm gear 21 and worm wheel 22 then rotates rotating arm 23, followed by worm wheel 24. Gear 28 then drives gear 26 to rotate, causing the locking pin 30 to rotate within worm gear 25. Worm gear 25 meshes with worm wheel 24, which in turn rotates gear 26 above worm gear 25. Gear 26 meshes with gear 28, causing the locking pin 30 to rise and fall. This, in turn, drives the stirring paddle 27 to stir the paint, ensuring the composition of the paint remains consistent at the microscopic level, thereby improving coating quality.
