Description

Technical Field

[0001] This utility model relates to the technical field of coating proportioning equipment, specifically an environmentally friendly automatic coating proportioning device. Background Technology

[0002] In the production process of bearings with mounting bases, the proportioning of the coating is a crucial step. Bearings with mounting bases typically require a specific coating to provide corrosion and rust prevention, and the precise proportions of the coating components directly affect the coating's performance and quality. Traditional coating proportioning methods largely rely on manual operation. Operators must manually weigh various coating components, such as resins, pigments, solvents, and additives, based on experience and formula requirements, and then pour them into a mixing container for stirring. This manual method has several drawbacks. Firstly, the accuracy of manual weighing is easily affected by the operator's subjective factors, such as reading errors and operational negligence, leading to inaccurate proportions of components. This, in turn, affects the coating's performance, potentially causing uneven coating thickness, poor adhesion, and insufficient corrosion resistance, reducing the bearing's lifespan and reliability. Secondly, manual operation is inefficient, especially in large-scale production, requiring significant manpower and time, making it difficult to meet the demands of modern, high-efficiency, and mass production. Therefore, new types of coating proportioning equipment have emerged in the market.

[0003] For example, utility model patent CN222446129U discloses a proportioning device for preparing environmentally friendly powder coatings, including: a box and a weighing cylinder. A collection box is slidably connected to the bottom of the box, a top plate is provided on the top of the box, and a proportioning box is provided on the top plate. A weighing scale and a cylinder are provided inside the proportioning box. A telescopic connecting rod is rotatably connected inside the proportioning box. The telescopic connecting rod is rotatably connected to the weighing cylinder. A first feed hopper is provided at the top of the proportioning box. A connecting seat is provided on the weighing cylinder, and a connecting rod is provided on the connecting seat. The output end of the cylinder is rotatably connected to the connecting rod.

[0004] The coating preparation proportioning device provided by the aforementioned patent integrates proportioning, weighing, and raw material mixing into a single device, simplifying the workflow and significantly improving work efficiency. However, this coating proportioning device is designed for powder coatings, while bearing production primarily uses liquid coatings, which are mostly mixed manually, requiring the addition of various ingredients. During the manual proportioning of liquid coatings, volatile components such as solvents can easily evaporate into the air, causing environmental pollution and posing health risks to operators. Furthermore, manual operation may result in paint spills and waste, increasing production costs and creating additional waste disposal problems. Utility Model Content

[0061] like Figure 9 and Figure 10 As shown, the liquid level sensor 9 has a hexagonal body 91 at its bottom, which facilitates the flexible assembly and disassembly of the liquid level sensor 9, making it easy to use. A sensing probe 92 is located in the middle of the hexagonal body 91, and the sensing probe 92 is threadedly connected to a threaded hole 82. The liquid level sensor 9 integrates a microprocessor, which is connected to a signal processing module and a wireless communication module. The signal processing module processes the signal detected by the liquid level sensor 9, and the wireless communication module transmits the processed signal wirelessly to the control box 11.

[0062] Working Principle: Operators input coating ratio parameters, mixing time, and mixing speed into the control box 11. Based on this information, the control calculation module inside the control box 11 controls the metering pump 74 at the bottom of the storage tank 7 to operate. The metering pump 74 delivers various materials to the mixing tank 2 according to the set flow rate. During the delivery process, the liquid level sensor 9 monitors the liquid level of the material and ensures accurate metering. After the material enters the mixing tank 2, the stirring component 4 starts working to stir and mix the material. After mixing, the mixed coating is output to the subsequent production process through the discharge pipe 21 at the bottom of the mixing tank 2. Throughout the process, the waste gas treatment component 5 collects and treats the volatile harmful gases, reducing environmental pollution.

[0063] In summary, compared with the prior art, this application, by setting up a mixing tank 2 and a storage tank 7, with a metering pump 74 at the bottom of the storage tank 7, achieves automatic coating proportioning through the control box 11 and the metering pump 74. This ensures accurate delivery of various materials according to the set proportioning parameters, improving proportioning accuracy and guaranteeing the stability of coating performance, thereby enhancing the coating quality with the base bearing. Furthermore, the tank cover 3 is connected to a waste gas treatment component 5, which can adsorb and treat the gas generated in the mixing tank 2, removing harmful organic matter from the waste gas.
